Regulatory Oversight Report on the Use of Nuclear Substances in Canada: 2022

Executive summary

The Regulatory Oversight Report on the Use of Nuclear Substances in Canada: 2022 provides information on the use of nuclear substances in the medical, industrial, academic and research, and commercial sectors. Licensees covered by this report are located across Canada, and Canadian Nuclear Safety Commission (CNSC) staff acknowledge all relevant treaties and all traditional territories on which the licensees are situated. Most of these licensees are regulated by the CNSC’s Directorate of Nuclear Substance Regulation (DNSR). The regulatory oversight report (ROR) also includes selected waste nuclear substance licensees that are not reported on in other RORs and that are regulated by the Directorate of Nuclear Cycle and Facilities Regulation.

The report on licensee performance for the 2 high-energy research particle accelerators, which was last incorporated into the 2019 nuclear substances ROR presented in 2020, is on a 3-year reporting cycle and would have been included in this ROR. However, these facilities and their performance reporting are more like that of other major CNSC-regulated facilities in Canada and will therefore be reported on in the Research Reactors and Particle Accelerator Facilities ROR in 2024, which are also on a 3-year reporting cycle. These 2 licensees did have full Commission licensing hearings, with interventions, in 2022.

Based on their assessment of licensee performance results for 2022, CNSC staff continue to conclude that nuclear substances in Canada are used safely. This conclusion is based on an analysis of the indicators covered in this report – inspection compliance ratings, enforcement actions, doses to workers, and event reports. In response to questions from the Commission in 2022 on the compliance ratings indicator, this year’s report provides additional context on how CNSC staff interpret those ratings. Staff have included new sections on the role that licensing activities play in assessing compliance and on how they calculate inspection ratings, to shed light on why there can appear to be downward trends in compliance when there are no actual performance issues within a sector or subsector. Staff have moved away from comparing in-year compliance data to the ratings from the previous year, and instead are comparing in-year compliance data against the 5-year averages of compliance results. This approach takes into account the fact that different licensees are inspected every year and provides a clearer view of performance trending. Lastly, CNSC staff have further explained the “unacceptable” versus “below expectations” ratings in order to distinguish between risks to health and safety requiring immediate action and overall performance trends requiring longer-term regulatory strategies.

In addition to the detailed explanation of performance ratings for the sectors in general, staff have also included an analysis of the radiation protection safety and control area within the nuclear medicine subsector. Licensee performance in this subsector has been of interest to the Commission and intervenors, and the analysis more clearly communicates the sources of non-compliance and the CNSC’s regulatory response.

Responsiveness and transparency are key elements of the CNSC’s commitment to building trust in the nuclear regulator. In addition to the changes to the ROR described above, prompted by Commission and intervenor feedback, CNSC staff contacted all intervenors on the 2021 ROR individually to respond to their comments directly and in more detail than was provided during the Commission proceeding in November 2022.

Based on the CNSC’s regulatory oversight, the evaluations presented in this report confirm the following:

• The use of nuclear substances and prescribed equipment in Canada remains safe and secure. “Unacceptable” ratings were issued in only 0.6% of inspections, and the associated non-compliances were corrected in a timely manner.
• Doses to workers remain low. No nuclear energy workers (NEWs) exceeded the regulatory dose limits, and less than 0.01% of non-NEWs reported doses greater than the regulatory limit of 1 mSv/year.
• Escalated enforcement actions are used when deemed necessary to ensure safety and security. Only 0.6% of inspections resulted in the issuance of an order.
• Events are reported, and corrective actions are implemented when required. More than 98% of reported events were considered to be of no safety significance based on the International Nuclear and Radiological Event Scale; no events were rated at higher than 1 on that scale.
• Engagement and outreach with industry, the public and other stakeholders are key to openness and transparency.

Overall, licensees made adequate provisions to protect health, safety, security and the environment with respect to the use of nuclear substances and prescribed equipment, and took the measures required to implement Canada’s international obligations and commitments.

Use of nuclear substances in Canada: 2022

The Regulatory Oversight Report on the Use of Nuclear Substances in Canada: 2022 summarizes the safety performance of 1,479 licensees holding a total of 2,080 licences. The Canadian Nuclear Safety Commission (CNSC) authorizes licensees to use nuclear substances and prescribed equipment in the medical, industrial, academic and research, and commercial sectors. For a description of the licensed activities covered in this report, refer to appendix A. Additional data on licensees covered by this ROR is available in appendix B.

CNSC staff use many metrics to evaluate licensees’ safety and security performance. This ROR uses a subset of those metrics, which, when taken together, provide a well-rounded picture of the performance of licensees. The metrics used in this report are:

• compliance performance
• enforcement actions
• doses to workers
• reportable events

In addition to the standard review of performance indicators, the 2022 ROR also includes an overview of the licensing process and information related to safeguards and other international commitments. The 2022 ROR also provides an update on the situation at Mississauga Metals & Alloys Inc. Lastly, the report provides the Commission with information about stakeholder engagement, which is a critical element of the CNSC’s regulatory approach.

This ROR includes data in both the body and appendices. The main body of the report provides a high-level overview of the CNSC’s regulatory efforts and the licensees’ performance, while the detailed data to support this overview is found in the appendices.

1.0 Licensing overview

This section provides an overview of the licensing process as it applies to licences covered by this report and is meant to highlight the importance of licensing as a foundational piece of compliance oversight. Licensing oversight plays a key role in supporting licensee performance, and high-quality assessments help ensure that licensees have strong programs in place.

The Nuclear Safety and Control Act (NSCA) authorizes the CNSC to issue licences to applicants who, in the opinion of the CNSC:

• are qualified to undertake the proposed licensed activity
• will make adequate provisions for the health and safety of persons, the protection of the environment and the maintenance of national security
• will take the measures necessary to implement international obligations to which Canada has agreed

The General Nuclear Safety and Control Regulations, the Nuclear Substances and Radiation Devices Regulations and the Class II Nuclear Facilities and Prescribed Equipment Regulations lay out requirements for licence applications. The CNSC’s REGDOC-1.6.1, Licence Application Guide: Nuclear Substances and Radiation Devices, provides guidance to prospective and current licensees on how to complete and submit an application for a CNSC licence for nuclear substances and radiation devices in accordance with the NSCA and the regulations made under it. REGDOC-1.4.1, Licence Application Guide: Class II Nuclear Facilities and Prescribed Equipment, identifies the information to be provided in support of an application for a licence to:

• construct, operate or decommission a Class II nuclear facility
• operate Class II prescribed equipment not installed in a facility
• service Class II prescribed equipment
• possess, use, store, transfer, import or export a nuclear substance used in manual brachytherapy, incorporated in Class II prescribed equipment, or otherwise associated with the licensed activity

While there is no specific licence application guide for waste nuclear substances, applicants must comply with the application requirements as laid out in the regulations.

The CNSC licensing process starts with an applicant’s submission for a new licence or for an amendment, renewal or revocation of a current licence. CNSC staff assess the application for such things as completeness and the adequacy of radiation safety and training manuals.

CNSC staff perform risk-informed technical assessments of applications submitted to the CNSC to ensure that the applicant is capable of and committed to complying with NSCA requirements, as well as the requirement to maintain an effective radiation safety program in accordance with the Radiation Protection Regulations. The licence application guides, created to ensure that expectations for applicants are clear and to facilitate applicants’ interactions with the CNSC, assist applicants in providing the information needed by the CNSC to make this determination. The level of information that must be submitted and the expected complexity of the radiation protection program when applying for a licence are commensurate with the risk of the licensed activity.

For licence renewals, licensees are requested to submit the renewal application a minimum of 2 months prior to the expiry of the existing licence. Renewal applications may refer to information previously submitted to the CNSC if the information has not changed. The level of technical assessment required by staff varies depending on the new information provided by the licensee. The option of referencing previously submitted information reduces the burden on both the licensee and CNSC staff and ensures that licence renewals can be issued in a timely manner. In addition to reviewing the submitted application, CNSC staff review compliance information such as inspection results, reported events and annual compliance reports before making a licensing decision. In the event of poor compliance history, while a licence may still be issued, the authorized activities could be limited or the licence period could be shortened.

During the licence period, there may be circumstances that require a change to the licence. The information required to amend a licence will vary depending on the change. Each amendment request is reviewed with the same risk-informed lens as any application. Amendments may be required for a variety of circumstances, including changes to the regulatory program, the licensed activities, the nuclear substances or prescribed equipment authorized by the licence, or the licensed locations. Administrative changes, such as a change in company name, also require an amendment to the licence.

Designated officers (DOs) are staff members in specific positions who are authorized by the Commission to carry out specific duties under section 37 of the NSCA. Given the large number of licences in this group and the relatively low risk to the public, the Commission has authorized DOs to make decisions related to the licensees covered in this report, including issuing, renewing and amending licences. If an application satisfies all CNSC requirements, a DO authorized by the Commission may issue a licence authorizing the licensee to conduct the activities requested in the application. The licence includes provisions that define and limit the scope of the authorized activities, as well as specific conditions that must be fulfilled by the licensee when conducting those activities. As per the licence conditions, licensees must inform the CNSC of any changes to their approved programs. Additional information about designated officer decisions can be found in appendix B.1.

Rigorous assessments of licensee programs, along with timely desktop reviews of annual reports and changes submitted by the licensee, are critical in ensuring that licensees have appropriate programs and people in place for the safe and secure use of nuclear substances in Canada.

2.0 Inspection overview in 2022

With COVID-19 still impacting inspections in the early part of the year due to the presence of the Omicron variant, the CNSC continued to balance regulatory oversight with the health and safety of CNSC and licensee staff. Inspections in 2022 included a mix of remote, in-person and hybrid inspections.

In 2022, staff performed 656 inspections (561 in-person, 16 hybrid and 79 remote). Figure 1 shows the transition in the types of inspections performed from 2021 to 2022, with the number of in-person inspections increasing and the number of remote inspections decreasing. Staff see this as a positive trend; while remote inspections are a useful tool, CNSC staff believe that, in most cases, onsite inspections are the preferred option.

Figure 1: Text version

A graphical comparison of the number of inspections by type performed in 2021 and 2022. In 2021, there were 233 in-person, 9 hybrid and 341 remote inspections performed. In 2022, there were 561 in-person, 16 hybrid and 79 remote inspections performed.

Most of the inspections (90%) were conducted in the industrial and medical sectors, as shown in figure 2. This is to be expected, as these 2 sectors make up approximately 79% of all licences.

Figure 2: Text version

A graph shows the percentage of inspections by sector: industrial (69%), medical (21%), commercial (5%), and academic and research (5%).

The inspection planning process used by CNSC staff takes a risk-informed approach that prioritizes the most critical inspections by applying a baseline inspection frequency and taking into account other factors, such as declining performance. This process was described in detail in section 2.0 of the 2021 ROR.

In 2022, staff prioritized inspections of medium-risk licensed activities that were overdue for their baseline inspections over higher risk licensed activities that had been inspected more recently, in a deliberate, risk-informed decision that made the most effective and efficient use of resources without compromising safety.

The number of inspections increased in 2022 compared to 2021, and staff were able to complete approximately 86% of the planned inspections (656 of 762). It should be noted, however, that most of the high-priority inspections (90%) were completed as planned. Inspections were not completed or were deferred for a number of reasons, including:

• the impact of performing remote inspections, especially in the early part of the year (e.g., certain types of inspections, such as field inspections, do not lend themselves well to remote inspections)
• staffing level fluctuations and onboarding of new inspectors
• licensees not operating at the time of the planned inspection
• licensees not having nuclear substances or radiation devices in their possession at the time of the planned inspection
• issues in transmitting classified information for planned remote security inspections

CNSC staff continued to address the inspection backlog caused by pandemic restrictions and continued to increase the number of annual inspections to regain the baseline inspection frequency determined by the CNSC’s risk-informed compliance program. Primary responsibility for safety lies with the licensee; therefore, the CNSC expects licensees to comply with regulatory requirements whether they are subject to a CNSC inspection or not. Nonetheless, inspections are an important component of regulatory oversight that allow the CNSC to verify licensee compliance with those requirements. Moreover, they provide an opportunity for inspectors to intervene early with licensees when performance starts to decline. As the number of inspections increases, staff presence at licensee sites will be a reminder to licensees that regulatory oversight and compliance with regulatory requirements continue to be priorities for the CNSC. In the meantime, the risk-informed planning process allows CNSC staff to maintain assurance that the nuclear substances sector continues to be safe despite the lower number of inspections.

While inspections are important, they are not the only regulatory oversight tool available to the CNSC to assess licensee compliance. Throughout 2022, CNSC staff also reviewed over 1,400 annual compliance reports submitted by licensees and followed up on more than 160 reported events. Both activities can provide indicators of licensee performance to supplement inspection findings. In addition, licensee programs are reviewed and evaluated as part of licence assessments, as described in section 1.0 of this report.

Considering the full suite of compliance activities, as well as the ability to prioritize the most risk-significant inspections, CNSC staff have concluded that the impact on licensee performance from the continued reduced number of inspections in 2022 remains acceptable.

3.0 Compliance overview

Overview of the compliance framework

To measure licensee performance, CNSC staff use the well-established Safety and Control Area Framework. The framework includes 14 safety and control areas (SCAs) covering all technical areas of regulatory oversight. During licensing and compliance activities, CNSC staff evaluate the licensee’s performance within each relevant SCA by reviewing licensee documents and conducting inspections. Owing to the broad nature of the different activities conducted by the licensees covered, not all SCAs apply to all activities or all licensees. CNSC staff acknowledge that all SCAs are important; however, the ROR focuses on those that are most effective in providing an overall indication of the safety performance of the licensees, namely, the management system, operating performance, radiation protection, and security SCAs. Performance data in the environmental protection and the conventional health and safety SCAs is also provided for the waste nuclear substance licensees. These licensees, unlike other licensees covered by this report, have a higher potential for environmental releases and, given the nature of the work performed, there is a potentially higher risk in conventional health and safety.

All relevant SCAs are assessed during inspections, and individual SCAs normally include multiple assessment areas. The areas or items to be assessed arise from regulatory requirements, licence conditions, and documents referenced in the licence. Compliance ratings for each SCA are calculated at the end of each inspection or, in the case of waste nuclear substance licences, on an annual basis.

A description of the ratings is provided in appendix J.

Overall analysis of 2022 compliance results

A total of 4 unacceptable ratings, as defined by the CNSC, were issued in 2022. All 4 unacceptable ratings were issued in the radiation protection SCA to 2 industrial sector licensees. Three of the unacceptable ratings were issued to a single portable gauge licensee and the fourth was issued to a fixed gauge licensee. Orders were issued to both licensees in response to these unacceptable ratings. In both cases, the licensees corrected all items of non-compliance and demonstrated that an effective radiation safety program had been implemented to the satisfaction of the CNSC before the order was closed. Additional information on these unacceptable ratings can be found in section 3.3. No unacceptable ratings were issued in the SCAs not covered in this report.

A list of inspections performed in 2022 is available in appendix H. Where items of non-compliance were identified, CNSC staff verified that licensees took appropriate corrective actions. Licensees promptly addressed any items of non-compliance that had immediate risks to health, safety or security.

Overall licensee performance has remained relatively stable over the past 5 years in all SCAs covered by this report. At the subsector level, there is more variation: some areas continue to see lower or declining performance, while others show improving performance. A brief overview of the SCAs is provided starting in section 3.1, with more details provided in appendix C. Appendix D presents the inspection results by subsector, offering another perspective on licensee performance in 2022.

Before discussing compliance performance trends in greater detail, and in response to feedback received from the Commission on the 2021 ROR, the following section has been added to provide more context to assist in interpreting performance data.

Calculating an SCA rating

When considering the performance data summarized in this report, it is important to understand how an SCA rating is reached. Individual SCAs include multiple assessment areas; the areas or items to be assessed arise from regulatory requirements, licence conditions, and documents referenced in the licence. Each area or item being assessed is assigned a risk ranking. Some of the requirements are administrative in nature and are considered relatively low risk, while others are linked to a potentially higher risk to health, safety or security. Note that when an inspection finds that an immediate risk exists, the licensee must address the issue right away.

All areas assessed within a given SCA impact the overall rating of that SCA. Non-compliances identified in relation to a higher risk requirement have more impact on the overall SCA rating than non-compliances identified in relation to a low-risk requirement. In fact, a single high-risk requirement that receives a below expectation rating will drop the overall performance in that SCA to below expectations. Examples of high-risk items from the SCAs covered in this report include thyroid monitoring requirements, calibration of survey meters, ascertainment and recording of doses, worker obligations, and the use of equipment and procedures. This conservative approach to rating licensee performance impacts the overall trends at the sector and subsector level.

Furthermore, this effect can be amplified during inspections of licensees who have larger numbers of workers and/or additional requirements placed on them due to the nature of the licensed activities performed. For example, while 9 out of 10 staff may have performed their thyroid monitoring at appropriate intervals over the period between inspections, if one worker missed one measurement in this period, they are deemed to be non-compliant and, because this is a high-risk line item, the entire SCA is rated as being below expectations. This does not necessarily point to a failure in the licensee’s programs or indicate unsafe work practices.

Additional considerations

When interpreting compliance performance data, it is also important to bear in mind that the data reported in the ROR reflects the licensee’s performance at the time of inspection and does not capture the effect of subsequent compliance activities. In reality, following an inspection that has yielded any below expectations ratings, CNSC staff track and follow up on all required corrective actions to ensure that all items of non-compliance have been addressed to their satisfaction (in other words, to ensure that the licensee has returned to a satisfactory rating). However, the improvements in performance will not be reflected in the ROR until that licensee is next inspected. This is why it is more meaningful to look at performance trends over a 5-year span, rather than the in-year or year-over-year performance results.

Lastly, in the context of safety significance, when reviewing the compliance data, the metric of primary relevance is the number of unacceptable ratings. In contrast to a below expectations rating, staff will issue unacceptable ratings in cases where licensee actions are unsafe. These situations are addressed immediately, typically through the issuance of an order, which is not closed until the CNSC is satisfied with the licensee’s corrective actions. As noted above, in 2022, only 4 unacceptable ratings were issued across all SCAs.

3.1 Management system

The management system SCA covers the framework that establishes the processes and programs required to ensure that an organization achieves its safety objectives, continuously monitors its performance against those objectives, and fosters a healthy safety culture.

In 2022, all sectors performed well in this SCA, with 98% of inspections receiving satisfactory ratings. This is comparable to the 5-year average of 97%. There were no unacceptable ratings in this SCA.

Refer to appendix C.1 and appendix D for additional information.

3.2 Operating performance

The operating performance SCA refers to the licensee’s ability to perform licensed activities in accordance with pertinent operational and safety requirements defined in the NSCA, in its associated regulations, and in the licence conditions. Licensees are expected to demonstrate that they comply with operational and safety requirements by providing workers with appropriate procedures for the safe use of nuclear substances and prescribed equipment, by ensuring that workers follow procedures, and by maintaining records that demonstrate compliance.

In 2022, overall licensee performance in this SCA remained stable, with 85% of inspections yielding satisfactory ratings, which is the same as the 5-year average. While the industrial sector showed stable performance overall compared to the 5-year average for the sector, the fixed gauge subsector demonstrated continued low performance in this area, as seen in table 9. As a reminder to licensees in this subsector, in early 2023, as part of a wider DNSR Digest article that discussed the most common non-compliances by sector, staff re-shared a detailed checklist on vessel entry, since this is one of the areas of continuing non-compliance for licensees in the fixed gauge subsector. In 2022, the DNSR Digest was also used to circulate information on preparing for inspections for all licensees. Staff continue to employ graduated enforcement tools to attempt to improve licensee performance in this area.

There were no unacceptable ratings in this SCA.

Refer to appendix C.2 and appendix D for additional information.

3.3 Radiation protection

Every licensee is required to put in place a radiation protection program to ensure that contamination levels and radiation doses received by workers are monitored, controlled, maintained below regulatory dose limits, and kept at levels that are as low as reasonably achievable (ALARA), with social and economic factors being taken into account. Licensees are expected to monitor worker doses; post radiation warning signs; plan appropriately for radiological emergencies; manage oversight of operational activities; institute effective workplace practices that emphasize the use of time, distance and shielding to minimize exposure to radiation; and use appropriate protective equipment.

Overall, there has been a decrease in the number of licensees receiving satisfactory ratings in the radiation protection SCA. In 2022, 77% of those inspected received satisfactory ratings compared to 81% averaged over the last 5 years. While the academic and research sector and the commercial sector remained stable compared to the 5-year average, both the medical sector and the industrial sector showed declining performance. In the medical sector, 68% of inspected licensees achieved satisfactory ratings in this SCA in 2022 compared to 75% averaged over the last 5 years. In particular, in the nuclear medicine subsector, only 63% of the 91 inspections performed resulted in satisfactory ratings. In the industrial sector, 77% of inspections resulted in satisfactory rating in 2022, which is lower than the 82% averaged over the last 5 years. Specifically, the portable gauge and fixed gauge subsectors showed marked changes in performance in this SCA: 71% of the 210 portable gauge licensees inspected and 74% of the 91 fixed gauge licensees achieved satisfactory ratings.

The poor performance of the nuclear medicine subsector in the radiation protection SCA has been highlighted in the past few RORs. In 2022, CNSC staff conducted a more detailed analysis of the compliance data for this SCA in general, which revealed that the anticipated transition period following the publication of the revised Radiation Protection Regulations, which came into force in late 2020, is continuing to have an impact. Further analysis of the nuclear medicine subsector revealed that approximately 18% of inspected licensees received notices of non-compliance in this SCA that related to the amended regulations, most commonly with respect to new requirements surrounding extremity dosimetry and radiation detection and measurement instrumentation. This led to a rating of below expectations in the radiation protection SCA for those licensees. In other words, non-compliances related to the implementation of the amended regulations by a small number of licensees in the nuclear medicine subsector is reflecting poorly on the entire subsector.

This sort of analysis provides a better understanding of the sources of non-compliances so that appropriate regulatory action can be taken, in this case, by continuing to focus CNSC efforts on ensuring that licensees understand and implement the amendments. For example, CNSC staff issued a DNSR Digest article in 2022 on extremity dosimetry requirements and the provision of information to NEWs. Additional outreach is being planned on the implementation of the new requirements, specifically in the areas where licensees are finding it difficult to demonstrate compliance, such as those related to radiation detection and measurement instrumentation. CNSC staff anticipate that once these issues have been addressed, the satisfactory ratings in the nuclear medicine subsector should increase.

There were 4 unacceptable ratings issued in this SCA. Of that number, 3 were issued to 1 portable gauge licensee as part of multiple inspections of that licensee. Order 1235 was issued in response to the licensee’s poor compliance. The inspector found that the licensee had failed to implement a radiation protection program that included an adequate level of management oversight of work practices and personnel qualification and training. The fourth unacceptable rating was issued to a fixed gauge licensee, and order 0600 was issued in response to the findings. The inspection identified repeated items of non-compliance related to worker training, records of authorized workers, and survey meter availability and calibration. In both cases, the licensees complied with the terms of the orders to the satisfaction of the CNSC and the orders were closed.

Refer to appendix C.3 and appendix D for additional information.

3.4 Security

Licensees are required to have in place physical security measures, practices and programs to prevent the loss, illegal use, illegal possession or illegal removal of nuclear substances during their entire lifecycle, including while they are in storage or during transport, as per the NSCA. The extent of the security measures required depends on the types of nuclear substances used and activities performed by each licensee.

In 2022, nuclear substance licensees maintained strong compliance with the security requirements, including the general requirements contained in the regulations and in REGDOC-2.12.3, Security of Nuclear Substances: Sealed Sources and Category I, II and III Nuclear Material, applicable to sealed sources and radiation devices, with 92% of licensees inspected in this SCA receiving satisfactory ratings. Although there was some fluctuation between sectors, overall, the rate has remained stable and consistent with the 5-year average of 93%.

The drop in compliance in the medical sector in 2021 was rectified in 2022, with licensees in that sector returning to previous levels of compliance. The return to more in-person inspections allowed for more than double the number of inspections to be performed in this SCA in comparison to 2020 and 2021.

The additional data obtained from an increased number of inspections, particularly in the medical sector, confirmed CNSC staff’s findings that all sectors performed well in this SCA in 2022.

There were no unacceptable ratings in this SCA.

Refer to appendix C.4 and appendix D for additional information.

3.5 Conventional health and safety for waste nuclear substance licensees

The CNSC requires waste nuclear substance licensees (WNSLs) to have a program in place to manage workplace safety hazards and to protect workers, given the nature of the work and the introduction of other hazards that need to be mitigated. For example, WNSLs handle, process, store and transport different types of radioactive waste, which may require the use of overhead cranes and large equipment. The licensed activities directly introduce mechanical, ergonomic, chemical, electrical and fire hazards that need to be mitigated.

In 2022, no WNSLs received below expectations or unacceptable ratings in the conventional health and safety SCA.

The licensees continued to implement health and safety programs in accordance with the applicable occupational health and safety legislation to protect the health and safety of their workers.

3.6 Environmental protection for waste nuclear substance licensees

WNSLs are required to have specific programs in place to identify, control and monitor all releases of radioactive and hazardous substances and their effects on the environment.

In 2022, no WNSLs received below expectations or unacceptable ratings in the environmental protection SCA. The WNSLs continued to manage and monitor environmental releases relating to licensed activities.

WNSLs reported 3 events that could potentially have impacted the environment in 2022. Information on these events can be found in table 23 of appendix G (event IDs: WNSL-3, WNSL-7, WNSL-8). All radiological releases were below regulatory limits, and there was no impact on the health and safety of persons or on the environment. With regard to non-radiological parameters, in one event, municipal criteria were not met; however, no adverse effects were likely as a result of that situation.

For additional information on how the environmental protection SCA is considered for other licensees covered by this report, please see section 3.7 of the Regulatory Oversight Report on the Use of Nuclear Substances in Canada:2021.

4.0 Enforcement

The CNSC uses a graduated approach to enforcement in order to encourage compliance. When non-compliance (or continued non-compliance) has been identified, CNSC staff assess the significance of the non-compliance and determine the appropriate enforcement action, including, but not limited to, orders and administrative monetary penalties (AMPs). Most enforcement actions are issued as a result of findings during inspections.

In 2022, CNSC staff issued 5 orders and no AMPs. All orders were issued to licensees in the industrial sector, which is consistent with trends in previous years. Four orders were issued after inspections and 1 was issued when a licensee failed to renew its licence. All 5 orders are closed, and the CNSC is satisfied that the licensees have addressed the conditions of the orders.

Although the number of inspections increased in 2022 and there was an apparent decline in performance in some areas (as discussed in section 3.0), the number of enforcement actions issued actually decreased. While this may not be the expected outcome, it is an indication that there were only a very small number of occasions where non-compliance was serious enough to warrant the issuance of an order, which supports CNSC staff’s assessment that licensee performance remains acceptable. An order is generally only issued when there is an immediate risk to health, safety or security.

The CNSC responds to non-compliance by taking the actions necessary to restore full compliance. Regulatory judgment is applied and multiple factors, such as the severity of the non-compliance and the associated risk, are considered to determine the most appropriate enforcement strategy for a given situation.

Enforcement actions are posted on the CNSC’s regulatory actions web page as they are issued.

5.0 Effective doses to workers

Licensees are required to keep radiation doses to persons below regulatory limits and as low as reasonably achievable (ALARA) in accordance with the radiation protection program referenced in their licence.

Licensees must report the doses to their workers, whether estimated or measured, as part of their annual compliance reports (ACRs). In 2022, doses were reported for 53,822 workers in the 4 sectors. Of those workers, 19,812 were nuclear energy workers (NEWs). The remaining 34,010 were not identified as NEWs and are referred to as non-NEWs in this report. Exposures to radiation continued to be very low for workers covered in this ROR for 2022, consistent with previous reporting years.

In 2022, no NEWs received doses above the regulatory limit of 50 mSv per calendar year. Of the 34,010 non-NEWs for which doses were reported, there were 3 reported doses greater than the regulatory limit of 1 mSv/year, all in the medical sector.

One licensee reported that 2 clerks in the nuclear medicine subsector were reported to have received doses greater than 1 mSv (1.09 mSv and 1.62 mSv), which was deemed unlikely due to the nature of the work performed. The licensee submitted dose change requests for these workers; however, based on the information provided, CNSC staff could not rule out that the doses were real. The dose change requests were not approved.

A second licensee reported a single dose to a non-NEW above the 1 mSv/year limit, specifically a dose of 1.9 mSv, also in the nuclear medicine subsector. The radiation safety officer believes this dose was likely the result of how the dosimeter was stored when the worker in question was on holidays; however, the licensee was not able to reproduce the storage conditions and therefore could not ascertain what part of the dose could be attributed to how the dosimeter was stored. The licensee has opted not to request a dose change for this worker.

There was strong performance in all sectors in 2022, with doses to all workers remaining generally low. Of the 3 reported instances where non-NEWs exceeded the regulatory limit, none of them was believed to be a true dose to the worker.

6.0 Reportable events

Licensees are required to have programs in place to manage unplanned events and accidents. The events that warrant mandatory reporting and the content of those reports are set out in the NSCA, its regulations and the licence conditions. REGDOC-3.1.3, Reporting Requirements for Waste Nuclear Substance Licensees, Class II Nuclear Facilities and Users of Prescribed Equipment, Nuclear Substances and Radiation Devices, sets out requirements and guidance for reports and notifications that licensees must submit to the CNSC. CNSC staff review, assess and track all events reported by licensees.

Since 2014, reported events have been rated using the International Nuclear and Radiological Event Scale (INES), a 7-point scale for communicating the safety significance of nuclear and radiological events to the public. Note that the scale is not a tool for comparing safety performance among facilities or organizations, but rather, for effectively communicating the safety significance of events. CNSC staff assign a ranking to each event based on the INES scale. The events reported to the CNSC by the licensees covered in this ROR typically fall into level 0 (no safety significance) or level 1 (an anomaly that may have an impact on defence in depth).

CNSC staff assessed 167 events related to nuclear substances and prescribed equipment in 2022. Of those events, 164 were rated as INES level 0. The remaining 3 were rated as INES level 1 and were related to the theft of portable gauges. Two of the stolen gauges were recovered and 1 remains missing. The presumption with stolen portable gauges is that they were likely stolen for their potential value as a tool or that they were an incidental theft when a vehicle was stolen as opposed to being stolen for the purpose of obtaining radioactive material.

The 167 reportable events in 2022 represent a stable number when compared to the 171 reported in 2021. There has, however, been a shift in the type of events reported. Of note, there was a decrease in security-related events in 2022 (18 events) compared to 2021 (31 events), which saw an unusual spike in security breaches. Both the commercial and the medical sectors showed a decrease in security-related events in 2022. As reported in the 2021 ROR, one medical sector licensee reported multiple security events in 2021. After the licensee reviewed its program, staff performed a focused security inspection in 2022. The inspection resulted in a satisfactory rating for the security SCA for the licensee. In September 2021, a DNSR Digest on security reminders was sent to all licensees to remind them of their obligations with regard to the security of nuclear substances. The 2022 reporting levels are more consistent with reporting levels in the years prior to 2021. It is important to keep in mind that the actual risk presented by these security-related events was low and that no nuclear substances were lost as a result of any of the events. Licensees employ multi-layered security programs to prevent security-related consequences from occurring.

The other significant change in the type of events reported was an increase in transport-related events in 2022 (59 events) in comparison to 2021 (41 events). Out of the 167 reportable events in 2022, 59 (35%) were related to transport. For the most part (68%), transport events were related to minor motor vehicle accidents (MVAs) where there was no damage to the package being transported and no injury to the driver. Most other events involved minor damage to the packaging during transport or incorrectly packaged nuclear substances (e.g., mislabelled, categorized incorrectly, unexpected dose rate measurements upon receipt). None of these events resulted in any overexposures and none were considered risk-significant; all were rated as INES level 0. Almost a million packages containing nuclear substances are shipped each year in Canada, and only a fraction of a percentage of the total number of shipments are involved in reportable events. The small number of transport events reported in 2022, even though it was an increase from 2021, is not of concern to CNSC staff. In fact, the relatively low number of events – all of which were of low risk significance – provides an indicator of the overall level of safety of the transport of nuclear substances in Canada.

For all events reported to the CNSC, licensees implemented appropriate response measures to mitigate the impacts, limit radiation exposure to workers and the public, and maintain security. CNSC staff reviewed the measures in all cases and found them to be satisfactory.

6.1 Update on Mississauga Metals & Alloys Inc.

Mississauga Metals & Alloys, Inc. (MMA) declared bankruptcy on August 20, 2021, and its waste nuclear substance licence expired on February 28, 2022. In CNSC staff’s update to the Commission in November 2022 during the presentation of the Regulatory Oversight Report on the Use of Nuclear Substances in Canada: 2021, the safety and security of the site, the procurement process for the detailed characterization of the waste, and the ongoing discussions with various parties pertaining to the site were highlighted.

Since that update, a designated officer order was issued to Richter (bankruptcy trustee), MMA and 1420561 Ontario Inc. (landowner) on March 28, 2023. The order requires them to take measures to ensure the safety and security of the nuclear substances onsite, eventually culminating with the removal of the nuclear substances from the property. These entities subsequently had an opportunity to be heard by the Commission regarding the order. The Commission’s decision on the order had not been issued at the time of writing this report.

In addition, as a result of a site visit, an order was issued by an inspector to Mr. David Sharpe and MMA on May 24, 2023. The order requires them not to undertake any activities associated with the trailers containing the nuclear substances. On May 30, 2023, Mr. Sharpe and MMA confirmed that they did not wish to exercise their opportunity to be heard on this matter. On July 25, 2023, the designated officer confirmed the order issued on May 24, 2023.

The CNSC continues to engage with other levels of government about the site while ensuring the safety and security of the nuclear substances on the property.

7.0 Outreach and engagement

The CNSC carries out engagement and outreach activities to facilitate communication on licensed activities and regulatory expectations. Engagement and outreach are critical elements of the CNSC’s regulatory approach. Given the breadth of licensees regulated in the area of nuclear substances, a particular focus is on reaching and engaging with licensee communities, a practice that leads to increased awareness and better understanding of the regulatory process and requirements. CNSC staff leverage a variety of fora to engage with licensees and promote the use of the tools that are developed to support compliance with regulatory expectations.

In 2022, outreach was done through a combination of virtual and in-person sessions and through written communications. Outreach included participation in town hall sessions, regular publication of the DNSR Digest, emails to targeted groups of licensees, meetings with associations or working groups, presentations at industry conferences, and the publishing of articles in industry publications. To ensure the DNSR Digest is used to its best advantage (reaching all nuclear substance licensees except for the 4 WNSLs), CNSC staff reached out through the Digest in January 2023 to solicit feedback on any topics that licensees may be interested in hearing about. At the time of writing this report, no suggestions had been received by staff.

In addition to these outreach and engagement opportunities, after the presentation of the 2021 ROR on the use of nuclear substances in November 2022, CNSC staff reached out to the 3 stakeholders who took the opportunity to comment on the ROR through the intervention process: Canadian Environmental Law Association, Nuclear Transparency Project and Canadian Radiation Protection Association. For each intervention, staff created a table of comments and recommendations related to the ROR and responded to each one individually. Staff then shared the relevant responses with each intervenor and offered to meet with the stakeholders to discuss the responses if needed. Although receipt of the drafted responses was acknowledged by all 3 intervenors, at the time of writing this report, only 1 intervenor had requested a specific meeting with CNSC staff, to be held in mid-September prior to the presentation of this report. Table 26 and table 27 summarize the number of comments responded to and the number of comments by area of interest submitted by the intervenors.

To date, Indigenous Nations and communities have not expressed a specific interest in this ROR and very little interest in the licensed activities that it covers. However, upon request, CNSC staff have participated in general outreach activities with Indigenous Nations and communities to provide information on the packaging and transport of nuclear substances. In addition, staff participated in outreach and engagement activities for the proposed Wheeler River environmental assessment with Indigenous Nations and communities potentially impacted by the project, which included attending culture camps with 2 communities. CNSC staff explained the licensing process for a nuclear substance licence. CNSC staff remain open and committed to ongoing engagement and communication with any interested Indigenous Nations and communities who may express an interest in discussing the topics and licenses covered in this ROR.

Staff are committed to continued openness and transparency with licensees, Indigenous Nations and communities, the public and other stakeholders. For a complete list of outreach activities, refer to table 25 in appendix I.

8.0 Safeguards

The Government of Canada has obligations on the peaceful use of nuclear energy pursuant to the Treaty on the Non-proliferation of Nuclear Weapons. CNSC requirements for nuclear substance licensees relating to Canada’s international obligations are defined in the applicable regulations and licences.

Safeguards involve a system of inspection and other verification activities undertaken by the International Atomic Energy Agency (IAEA) to evaluate Canada’s compliance with its obligations under its safeguards agreements with the IAEA. The objective of the Canada–IAEA safeguards agreements is for the IAEA to provide assurance to Canada and to the international community that all declared nuclear materials are being used for peaceful, non-explosive purposes and that there is no indication of undeclared nuclear materials or activities. The CNSC has published REGDOC-2.13.1, Safeguards and Nuclear Material Accountancy, which sets out the requirements and guidance for the establishment and maintenance of a safeguards program. Safeguarded materials include uranium, thorium and plutonium-239. Generally, among the licensees covered in this report, this material can be present as samples, check sources and shielding, among other forms. Licensees subject to safeguards have a condition included in their licence, and the CNSC continues to engage with licensees to ensure that all nuclear material subject to safeguards is reported to the IAEA.

In 2022, the IAEA performed 4 inspections and 3 complementary accesses at the facilities of nuclear substance licensees to confirm licensees’ declarations on the possession and use of nuclear material. While the IAEA reported that the results of these inspections were satisfactory and that its inspectors were able to carry out all planned activities for the complementary accesses, it identified areas for improvement associated with maintaining proper segregation of exempted material from other sources and making some corrections to nuclear material documents (i.e., list of inventory items). None of these issues are safety-significant. The CNSC has communicated these areas of improvement to the affected licensees, and staff are monitoring the licensees’ corrective actions.

CNSC staff ensure that licensees implement the measures required to meet Canada’s international obligations.

9.0 International regulations and other commitments

The mandate of the CNSC includes adherence to international commitments to which Canada is a party.

Canada has committed to the implementation of various IAEA codes, standards and guidance documents. For example, as part of Canada’s commitment to the IAEA Code of Conduct on the Safety and Security of Radioactive Sources and the associated Guidance on the Import and Export of Radioactive Sources, nuclear substance licensees with Category 1 and/or 2 (high-risk) sealed sources must inform the CNSC of any transfer, receipt, export or import of those sources. Licensees report their high-risk sealed sources inventory through the Sealed Source Tracking System (SSTS). The SSTS is a secure information management system that tracks new and existing high-risk sources within Canada. It populates the National Sealed Source Registry so that the information is as current as licensee reporting allows. Licensees subject to this requirement have the relevant licence condition included in their licence, and compliance with this condition is verified through a regulatory inspection. Canada has also committed to the IAEA’s Guidance on the Management of Disused Radioactive Sources, which is supplementary guidance to the Code of Conduct and is intended to consolidate and provide details on the management of disused sources. Every 3 years, Canada must present a report on the implementation of the Code and its supplementary guidance at a meeting of IAEA member states. The most recent report covered the period from January 2019 to December 2022.

Nuclear substance licensees who import or export nuclear substances are subject to licence conditions that limit the types and amounts of nuclear substances that they can import or export without a separate, valid import/export licence. Licensees must meet the requirements set out in the Nuclear Non-proliferation Import and Export Control Regulations. In addition, REGDOC-2.13.2, Import and Export, sets out guidance for current and prospective licensees who intend to import or export risk-significant radioactive sources (Categories 1 and 2 radioactive sources). Compliance with import and export restrictions is verified during inspections.

In addition, the CNSC considers international regulations and standards when developing domestic regulations. For example, the Packaging and Transport of Nuclear Substances Regulations, 2015, with which all licensees and non-licensees must comply, incorporate by reference the IAEA Regulations for the Safe Transport of Radioactive Material. While this is the only case where the IAEA regulations are referenced directly in the domestic regulations, current CNSC regulations that apply to licensees covered by this report are generally based on international regulations and standards, including relevant safety standards and other IAEA publications.

In 2019, Canada was the subject of an IAEA Integrated Regulatory Review Service (IRRS) mission, the main purpose of which was to perform a peer review of Canada’s regulatory framework for nuclear and radiation safety against IAEA safety standards, which are the international benchmark for safety. Appendix VI of the final report includes a list of IAEA reference material used for the review. Based on this review, Canada was found to have a comprehensive and robust regulatory framework for nuclear and radiation safety covering current facilities and activities, including those covered by this regulatory oversight report. While not explicitly referenced, IAEA safety standards are translated into regulatory requirements or licence conditions for licensees covered in this report.

10.0 Conclusion

In 2022, most inspected licensees were in compliance with regulatory requirements and achieved satisfactory ratings in the SCAs reported on in this report. Licensing and certification activities continued to play a critical role in ensuring that effective licensee programs were in place, and these programs contributed significantly to overall licensee performance. Where compliance did not meet expectations, licensees implemented appropriate corrective actions. All 5 escalated enforcement actions issued in 2022 have been closed. Radiation exposure to workers continued to be very low and was consistent with previous years. When events did occur, licensees took appropriate measures to address the events and took steps to prevent recurrence. Staff continue to address the backlog of inspections and will continue to monitor for possible negative trends in compliance over the coming years.

The evaluations of the SCA findings, resulting from the CNSC’s comprehensive regulatory oversight of the industry, demonstrate that licensees made acceptable provisions to protect health, safety, security and the environment from the use of nuclear substances and prescribed equipment, and implemented the measures required to meet Canada’s international obligations. Based on these evaluations, CNSC staff conclude that the use of nuclear substances and prescribed equipment in Canada remains safe and secure.

Appendix A: Licensed activities covered in this report

Licensed activities covered in this report are extremely varied and, for ease of reporting, have been divided into 4 sectors: medical, industrial, academic and research, and commercial. Each of these sectors is described briefly below.

Medical

Licensees in the medical sector use nuclear substances and operate accelerators and other equipment for diagnostic and therapeutic purposes in hospitals and medical clinics. Medical applications using radiopharmaceuticals are designed to target specific tissues and organs, allowing for the delivery of nuclear substances to specific areas of the body for diagnostic testing or treatment.

Diagnostic nuclear medicine studies assist in the diagnosis of medical conditions based on the physiological functions of organs, tissues or bones. Radiopharmaceuticals containing nuclear substances such as technetium-99m, gallium-67 and fluorine-18 are administered to patients for imaging purposes. Examples of common nuclear medicine diagnostic procedures include cardiac scans (to visualize heart function and blood flow), bone scans (to evaluate bone metabolism, infection or tumours) and renal scans (to evaluate kidney function).

Radioisotopes are also used in many therapeutic procedures. For example, iodine-131 is used to treat diseases of the thyroid gland, while other isotopes, such as yttrium-90, may be used in conjunction with antibodies for site-specific treatment of certain cancers.

Radiation therapy devices are used to treat cancer, either via an external beam of radiation or by placing radioactive sources inside cancerous tissues. Medical linear accelerators are the most common type of equipment used for therapeutic purposes. These devices are used to treat cancer by delivering carefully controlled doses of radiation to cancerous tissue.

Veterinary nuclear medicine uses techniques like those employed in human nuclear medicine. Veterinary clinics across the country offer a wide range of diagnostic and therapeutic nuclear medicine procedures and, in some cases, radiation therapy treatment using medical accelerators or teletherapy.

Industrial

Licensees in the industrial sector use nuclear substances either in industrial facilities or as part of fieldwork or construction. Typical applications include the measurement of physical parameters such as density, moisture content and geological composition in civil engineering. Nuclear substances are also used for material examination in civil engineering, and for level and flow rate measurements in industrial processes (such as oil and gas exploration, mining and manufacturing). They are found in radiation devices such as fixed nuclear gauges, which monitor production processes in many industries, and portable nuclear gauges, which are often used to measure moisture and density in soil and the compaction of asphalt in road construction.

In industrial radiography, nuclear substances are used in exposure devices for the non-destructive examination of materials. Anyone operating an exposure device or supervising a trainee in the operation of such device must be certified by the CNSC. Exposure devices used for industrial radiography are engineered and operated using multiple safety barriers to reduce the potential for accidental occupational exposure. One example is dense material, such as depleted uranium, which shields people against the intense radioactivity of the source contained inside the device.

Industrial applications of nuclear substances are as varied as the processes to which they are applied. Specific radioisotopes are chosen based on the type of radiation they emit, the intensity of their radiation and the intended application. For example, the nuclear substance chosen for industrial radiography depends on the size and density of the material to be imaged. Cobalt-60, with its high-energy gamma radiation, is used for large structures and dense materials such as structural concrete. When the material does not require the penetrating power of cobalt-60, other nuclear substances, such as iridium-192 or selenium-75, are used instead. Cesium-137, another gamma emitter, is most commonly used in portable and fixed gauges to measure density. In other industrial uses, like measuring moisture content for example, portable gauges most commonly use neutron-emitting nuclear substances such as americium-241/beryllium.

Academic and research

Licensed activities in the academic and research sector are conducted in universities, colleges and research laboratories, and focus mainly on biological and biomedical research that primarily uses open (unsealed) nuclear substances. This sector also uses sealed sources, radiation devices and accelerators for teaching and for pure and applied research, as well as irradiators to irradiate cells or samples in laboratories.

Commercial

Licensed activities in the commercial sector involve the production, processing, storage and distribution of nuclear substances, the calibration of radiation detection instruments, and the servicing of radiation devices and Class II prescribed equipment for commercial purposes. Waste nuclear substance licences also fall under the commercial sector.

Additional information about the licensed activities covered by this report can also be found in the technical briefing to the Commission on nuclear substances in Canada (CMD 18-M49) and on the CNSC website, which also includes various resources geared towards licensees.

Appendix B: Regulatory program for the use of nuclear substances

This appendix presents additional regulatory data to complement the information provided in the main part of the document.

B.1 Designated officer decisions

CNSC designated officers made a total of 2,045 licensing and certification decisions related to activities covered in this report in 2022. The majority of these were licensing decisions, as shown in table 1. There was no significant change in the number or type of decisions made compared to 2021.

Table 1: Designated officer licensing and certification decisions in 2022, all sectors combined

Type of decision	Number of decisions
Licensing (issuance of new licences, licence renewals, licence amendments, licence revocations and licence transfers)	1,619
Certification of prescribed equipment (radiation devices, Class II prescribed equipment, and transport packages)	69
Certification of exposure device operators (issuance of new certifications and renewal of certifications)	337
Certification of Class II radiation safety officers	20
Total	2,045

The CNSC’s risk-informed regulatory program applies resources and regulatory oversight commensurate with the risk associated with the regulated activity. Regulatory effort related to licensing, certification and compliance verification is derived from this program.

B.2 Licensing

In 2022, there were 2,080 nuclear substances and prescribed equipment licences (table 2) held by 1,479 licensees across Canada, as shown in figure 3. An additional 52 licences were held by companies headquartered in other countries (primarily the United States). Many of these companies service prescribed equipment located in Canada, while others have operational facilities in Canada.

The disparity between the number of licences and the number of licensees can be explained by the fact that while most licensees perform a single licensed activity and therefore require only one CNSC licence, others perform varied activities that require a licence for each one. For example, a hospital may have multiple licences to cover radiation therapy facilities, diagnostic nuclear medicine, therapeutic nuclear medicine, nuclear substance processing, and research labs, each of which is covered by its own licence given the unique requirements and programs. CNSC staff work with these licensees to ensure that an appropriate level of regulatory control is maintained, while minimizing administrative burden wherever possible.

An overview of the licensing process is available in section 1.0 of this ROR.

Newfoundland and Labrador: 20 industrial licences, 1 academic and research licence, 6 medical licences, 2 commercial licences (total of 29 licences)

In addition, 52 licences have been issued outside of Canada.

B.3 Certification of prescribed equipment

Certification of prescribed equipment confirms that the equipment is safe to use; that adequate measures are in place to protect the environment, the health, safety and security of persons, and national security; and that the design meets international requirements. Prescribed equipment includes radiation devices, Class II prescribed equipment, and transport packages, and the requirements for certification are set out in the regulations. As seen in table 1, designated officers made 69 decisions related to the certification of prescribed equipment in 2022, consistent with the 70 decisions made in 2021. As in the case of licensing, CNSC staff perform risk-informed technical assessments of certification applications submitted to the CNSC. The CNSC has regulatory documents in place to ensure that its expectations for applicants are clear. Service standards for the certification of Class II prescribed equipment, radiation devices, and transport packages are posted on the CNSC website. The lists of certified transport packages and special form radioactive material, Class II prescribed equipment and radiation devices are available on the CNSC website.

B.4 Certification of exposure device operators

Licensees are required under the Nuclear Substances and Radiation Devices Regulations to permit only CNSC-certified personnel and supervised trainees to use exposure devices containing nuclear substances. In 2022, the CNSC certified 69 new exposure device operators (EDOs) and renewed the certifications of 268 others, compared to 2021 when the CNSC certified 61 new EDOs and renewed 318 certifications. CSA Group’s CSA PCP-09: Exposure Device Operator Personnel Certification Guide, was revised and posted in January 2022 and fully implemented in August 2022. Additional information on the EDO program can be found on the CNSC website.

B.5 Certification of Class II radiation safety officers

All licensees that operate Class II nuclear facilities or that service Class II prescribed equipment must have a certified radiation safety officer (RSO) and a qualified temporary replacement. The RSO ensures that licensed activities are conducted safely and that all regulatory requirements are met.

In 2022, the CNSC certified 20 Class II RSOs, compared to 15 in 2021. As in 2021, no Class II RSOs were decertified in 2022.

In 2022, the CNSC published discussion paper DIS-22-01, Proposal to Amend the Class II Nuclear Facilities and Prescribed Equipment Regulations, which included potential revisions to the regulations, such as the introduction of provisions allowing for the amendment and expiry of certificates issued to Class II RSOs and for the recertification of RSOs. Since the comment period on this discussion paper closed in late 2022, the comments are still under review by CNSC staff.

Appendix C: Compliance performance

This appendix provides details regarding compliance in the 4 SCAs determined to be the most relevant in providing an overall indication of the safety performance of licensees in 2022.

It is important to note that a below expectations rating does not necessarily mean that a licensee’s actions were unsafe. It could mean any of the following: licensee performance does not meet CNSC staff expectations, the licensee has risk-significant non-compliance(s) or performance issue(s), and/or non-compliances or performance issues are not being adequately corrected. Staff will issue unacceptable ratings in cases where licensee actions are unsafe – in 2022, only 4 unacceptable ratings were issued across all SCAs.

In all cases, for any below expectations ratings, CNSC staff ensured that licensees took appropriate corrective actions. For all unacceptable ratings, CNSC staff issued orders or took licensing action, with restrictions lifted only once the CNSC was satisfied that all conditions had been addressed by the licensee.

Given the small number of WNSLs, specific data related to the environmental protection and the conventional health and safety SCAs is not included in this section.

C.1 Management system

Of the 597 inspections that looked at the management system SCA, 98% of the licensees inspected demonstrated that adequate processes and programs were in place to achieve their safety objectives and therefore received satisfactory ratings (figures 4 and 5). Figure 5a compares the 2022 ratings to the 5-year average by sector.

There were no unacceptable ratings in this SCA.

4.9% fewer inspections received satisfactory ratings in 2022 compared to the 5-year average in the industrial sector.

1.2% fewer inspections received satisfactory ratings in 2022 compared to the 5-year average in the academic and research sector.

0.5% fewer inspections received satisfactory ratings in 2022 compared to the 5-year average in the commercial sector.

4.7% fewer inspections received satisfactory ratings in 2022 compared to the 5-year average in all sectors combined.

C.4 Security

Of the 502 inspections that looked at the security SCA, 92% of the licensees inspected demonstrated that adequate processes and programs were in place to achieve their safety objectives and therefore received satisfactory ratings (figures 10 and 11). Figure 11a compares the 2022 ratings to the 5-year average by sector. The marked increase in the number of inspections of this SCA is directly related to the return to in-person inspections.

There were no unacceptable ratings in this SCA.

Appendix D:  Inspection ratings by sector

This section provides data at the sector and subsector levels for each of the 4 key SCAs covered in this report. Any significant findings at the SCA level have been further explained in section 3.0 of this report, where additional analysis is included for the management system, operating performance, radiation protection and security SCAs. Given the small number of WNSLs, specific data related to the environmental protection and the conventional health and safety SCAs are not included in this section.

A breakdown by subsector is not provided for the security SCA, given the potentially sensitive information associated with that SCA.

D.1 Medical sector

Tables 4 to 7 show the inspection performance of licensees in the medical sector. Subsector performance for the years 2018 to 2022 is shown as a percentage of the inspections that received satisfactory ratings for the SCA. The total number of inspections conducted to assess performance in the SCA appears in parentheses. The number of inspections shown in the “Entire medical sector” row is the aggregate for the entire sector, including subsectors not highlighted.

Table 4: Management system – Percentage of inspections with satisfactory ratings (and number of inspections conducted) for the medical sector and selected subsectors, 2018 to 2022

SCA	Subsector / sector	2018	2019	2020	2021	2022
Management system	Nuclear medicine	96% (103)	95% (103)	94% (47)	99% (89)	97% (76)
Management system	Radiation therapy	50% (6)	100% (4)	0% (1)	70% (10)	100% (9)
Management system	Veterinary nuclear medicine	100% (4)	75% (4)	(0)	100% (3)	100% (7)
Management system	Entire medical sector	94% (117)	95% (163)	92% (48)	96% (105)	98% (95)

Table 5: Operating performance – Percentage of inspections with satisfactory ratings (and number of inspections conducted) for the medical sector and selected subsectors, 2018 to 2022

SCA	Subsector / sector	2018	2019	2020	2021	2022
Operating performance	Nuclear medicine	77% (104)	87% (155)	77% (48)	83% (89)	84% (76)
Operating performance	Radiation therapy	67% (12)	100% (21)	100% (2)	90% (10)	100% (15)
Operating performance	Veterinary nuclear medicine	100% (4)	100% (3)	100% (1)	100% (3)	75% (8)
Operating performance	Entire medical sector	77% (124)	88% (176)	77% (51)	84% (115)	85% (103)

There was a significant drop in the performance of veterinary nuclear medicine licensees in this SCA; however, with the small number of inspections performed, it is difficult to say whether this is representative of the subsector as a whole given that this decrease was the result of only 2 inspections that received ratings of below expectations. Both of those inspections were priority 1 inspections as the licensees had not been seen in over 5 years.

Table 6: Radiation protection – Percentage of inspections with satisfactory ratings (and number of inspections conducted) for the medical sector and selected subsectors, 2018 to 2022

SCA	Subsector / sector	2018	2019	2020	2021	2022
Radiation protection	Nuclear medicine	74% (104)	70% (155)	73% (48)	75% (119)	63% (91)
Radiation protection	Radiation therapy	100% (12)	100% (13)	100% (2)	100% (20)	93% (15)
Radiation protection	Veterinary nuclear medicine	50% (4)	100% (3)	100% (1)	33% (3)	63% (8)
Radiation protection	Entire medical sector	77% (124)	74% (178)	76% (51)	78% (145)	68% (118)

The nuclear medicine subsector demonstrated lower performance in the radiation protection SCA in 2022 in comparison to previous years, although ratings have been consistently low over the last 5 years. The most frequent items of non-compliance in 2022 include the ascertainment and recording of doses, the failure to demonstrate that sampling and counting methods meet licence criteria for detecting loose contamination, and failure to post radiation warning signs that meet regulations. These items are related to inadequate management oversight in the implementation of the radiation protection program. CNSC staff continue to work with these licensees to correct items of non-compliance and to work on program deficiencies. While staff continue to prioritize inspections for medium-risk licensees, such as those in the nuclear medicine subsector, the focus is currently on those licensees that are overdue for inspections. Staff are satisfied with this prioritization, as most non-compliances are not serious in nature.

; however, with the small number of inspections performed, it is difficult to say whether this is representative of the subsector.

SCA	Sector	2018	2019	2020	2021	2022
Security	Medical sector	91% (119)	94% (168)	97% (33)	79% (34)	99% (81)

D.2 Industrial sector

Tables 8 to 11 show the inspection performance of licensees in the industrial sector. Subsector performance for the years 2018 to 2022 is shown as a percentage of the inspections that received satisfactory ratings for the SCA. The total number of inspections conducted to assess performance in the SCA appears in parentheses. The number of inspections for the “Entire industrial sector” row is the aggregate for the entire sector, including subsectors not highlighted.

A breakdown by subsector is not provided for the security SCA, given the potentially sensitive information associated with that SCA.

Management system	Entire industrial sector	97% (608)	98% (487)	96% (261)	97% (340)	98% (437)

Table 9: Operating performance – Percentage of inspections with satisfactory ratings (and number of inspections conducted) for the industrial sector and selected subsectors, 2018 to 2022

SCA	Subsector / sector	2018	2019	2020	2021	2022
Operating performance	Portable gauge	86% (326)	82% (216)	82% (98)	89% (192)	82% (210)
Operating performance	Fixed gauge	68% (111)	73% (124)	71% (94)	72% (64)	67% (91)
Operating performance	Industrial radiography	88% (138)	93% (114)	98% (66)	95% (82)	95% (107)
Operating performance	Oil-well logging	86% (44)	100% (24)	100% (9)	100% (14)	88% (24)
Operating performance	Entire industrial sector	83% (633)	84% (484)	82% (267)	88% (363)	83% (444)

The fixed gauge subsector continues to demonstrate low performance in the operating performance SCA. This finding has remained consistent over the last 5 years. The most frequent non-compliances in 2022 include failure to maintain appropriate worker records; failure of workers to ensure appropriate use of equipment, clothing and procedures onsite; and failure of workers to follow their obligations. Most of these non-compliances relate to licensees not following their established procedures, specifically in relation to internal audits, vessel entry, shutter checks and mounting/dismounting devices. CNSC staff continue to work with these licensees to correct items of non-compliance and to work on program deficiencies. CNSC staff used the DNSR Digest to circulate information on preparing for an inspection, including information on the use of internal inspections. CNSC staff have also engaged with licensees through specific outreach activities related to vessel entry procedures, as that was one area of declining performance. While staff continue to prioritize inspections for medium-risk licensees, such as those in the fixed gauge subsector, the current focus is on those licensees that are overdue for an inspection. Staff are satisfied with this prioritization, as most non-compliances are not serious in nature.

Table 10: Radiation protection – Percentage of inspections with satisfactory ratings (and number of inspections conducted) for the industrial sector and selected subsectors, 2018 to 2022

SCA	Subsector / sector	2018	2019	2020	2021	2022
Radiation protection	Portable gauge	84% (326)	74% (216)	83% (98)	81% (192)	71% (210)
Radiation protection	Fixed gauge	77% (111)	73% (124)	82% (94)	80% (64)	74% (91)
Radiation protection	Industrial radiography	91% (138)	92% (114)	86% (66)	93% (82)	89% (108)
Radiation protection	Oil-well logging	91% (44)	92% (24)	89% (9)	93% (14)	87% (23)
Radiation protection	Entire industrial sector	85% (633)	79% (483)	84% (267)	85% (364)	77% (444)

There has been an overall decrease in licensee performance in the radiation protection SCA across all subsectors, with a notable drop in performance in the fixed and portable gauge subsectors. The most frequent non-compliances in 2022 include failure to calibrate survey meters at the required frequency, failure of workers to ensure calibrated survey meters are available for use, and failure to post radiation warning signs that meet regulations. As mentioned previously, while staff continue to prioritize inspections for medium-risk licensees, such as those in the fixed and portable gauge subsectors, the current focus is on those licensees that are overdue for an inspection.

D.3 Academic and research sector

Tables 12 to 15 show the inspection performance of licensees in the academic and research sector. Subsector performance for the years 2018 to 2022 is shown as a percentage of the inspections that received satisfactory ratings for the SCA. The total number of inspections conducted to assess performance in the SCA appears in parentheses. The number of inspections for the “Entire academic and research sector” row is the aggregate for the entire sector, including subsectors not highlighted.

D.4 Commercial sector

Table 16 shows the inspection performance of licensees in the commercial sector. The performance of the sector for the years 2018 to 2022 is shown as a percentage of the inspections that received satisfactory ratings for the SCA. The total number of inspections conducted to assess performance in the SCA appears in parentheses. The number of inspections for the commercial sector is the aggregate for the entire sector.

In light of the small number of inspections in each subsector, a breakdown by subsector is not provided. It would be difficult to identify trends in the subsectors given the low number of licensees in many of them.

Appendix E: Enforcement actions issued in 2022

In 2022, CNSC staff issued 5 orders and no administrative monetary penalties (AMPs) to licensees. All enforcement actions were issued to licensees in the industrial sector. This is consistent with previous years, in which most, if not all, enforcement actions were issued in that sector.

A complete list of orders issued is included in table 17. All enforcement actions issued have been closed, and the CNSC is satisfied that the licensees have addressed the conditions of the orders.

Date of issue	Order #	Licensee and location	Subsector / sector	Order summary	Status
August 11, 2022	1235	R.M. Bélanger Limited 100 Radisson Avenue, Chelmsford, ON	Portable gauge / industrial	The order was issued following a CNSC onsite inspection on August 11, 2022, in Chelmsford and Sudbury, Ontario. The inspection identified a number of non-compliances related to training requirements, record keeping, ascertainment of doses, radiation detection instrumentation availability, and compliance with the requirements of the Transportation of Dangerous Goods Regulations when transporting the radiation devices. The findings indicated that the licensee failed to implement a radiation protection program that included an adequate level of management oversight of work practices and personnel qualification and training. The order required the licensee to cease all use and transport of radiation devices and immediately place all gauges into secure storage until such time as the licensee had demonstrated to the satisfaction of the CNSC that an effective radiation protection program had been put in place and that all items of non-compliance identified in addendum 1 of the order had been corrected.	The licensee complied with the terms of the order to the satisfaction of the CNSC. The order was closed on January 13, 2023.
August 18, 2022	1142	JR’s Salvage and Son Ltd. 56 Industrial Drive, Sussex, NB	X-ray fluorescence analysis / industrial	The order was issued because the licensee failed to submit a renewal application for the licence expiring on August 31, 2022. The order required the licensee to transfer all radiation devices in its possession to a licensee authorized by the CNSC to possess such devices and provide proof of the transfer via email by no later than August 31, 2022.	The licensee complied with the terms of the order to the satisfaction of the CNSC. The order was closed on July 25, 2023.
August 30, 2022	0600	KCS Plastics Ltd. 5965 – 206 Street, Langley, BC	Fixed gauge / industrial	The order was issued on August 30, 2022, following a CNSC inspection at the licensee’s facility in Langley, British Columbia. The inspection identified repeated items of non-compliance related to worker training, record of authorized workers, and survey meter availability/calibration. The order required the licensee to immediately cease all operations that involved the use of fixed nuclear gauges until such time as all items of non-compliance cited in the inspection report had been corrected and an effective radiation safety program had been implemented to the satisfaction of the CNSC.	The licensee complied with the terms of the order to the satisfaction of the CNSC. The order was closed on October 20, 2022.
October 25, 2022	1022	Aurora Inspections Limited 745048 Highway 2, Sexsmith, AB	Industrial radiography / industrial	The order was issued following a CNSC inspection on October 25, 2022, at the licensee’s location in Sexsmith, Alberta. A review of dosimetry reports during the inspection identified that the licensee had failed to report to the CNSC that its monthly, quarterly and/or annual action level dose limits had been exceeded by multiple workers. In addition, the inspection revealed that the licensee had failed to implement sufficient management oversight of the radiation safety program and work practices to ensure that doses were kept as low as reasonably achievable. The order required the licensee to prohibit one of its workers from operating an exposure device until such time as the licensee had confirmed in writing to the CNSC that there was sufficient management control over work practices and that workers were sufficiently trained on dose control, demonstrating to the satisfaction of the CNSC that an effective radiation safety program was in place.	The licensee complied with the terms of the order to the satisfaction of the CNSC. The order was closed on November 25, 2022.
November 17, 2022	0545	Labcan (1989) Ltée 175 Dessureault Street, Trois-Rivières, QC	Industrial radiography / industrial	The order was issued following a CNSC security inspection on November 17, 2022. The inspection identified non-compliances related to security requirements for transporting exposure devices in a vehicle. The order required the licensee to put in place adequate security measures for transporting an exposure device in a vehicle.	The licensee complied with the terms of the order to the satisfaction of the CNSC. The order was closed on January 13, 2023.

Appendix F: Doses to workers

Occupational doses were reported by licensees for a total of 53,822 workers in the 4 sectors in 2022. Of those workers, 19,812 were nuclear energy workers (NEWs). The difference in doses to workers among sectors reflects the nature of the various activities within those sectors. Figure 13 shows the doses received by non-NEWs reported in 2022, with 91% reported as having received doses less than or equal to 0.5 mSv. Figure 14 shows the doses received by NEWs reported in 2022. Based on the reported doses for NEWs, only about 20% received a dose greater than 1 mSv, and less than 2% received a dose above 5 mSv. Figure 15 shows the doses to NEWs from 2018 to 2022.

As the figures demonstrate, doses overall have remained low and stable over the years. This is an indication that industry has successfully kept doses as low as reasonably achievable. Given the nature of the work performed in many cases, it is inevitable that some workers will receive a dose. The constancy year over year indicates that doses have likely achieved a state of equilibrium – changes in operational procedures will likely not yield any significant improvement in dose.

To further increase the granularity of dose reporting, CNSC staff have updated the annual compliance report forms to subdivide the 1–5 mSv category into 1–2 mSv and 2–5 mSv categories. Staff will consider how this data will be presented in future RORs.

More information on doses is provided in section 5.0 of this report.

Appendix G: Reportable events

In 2022, CNSC staff received 206 notifications from licensees of potential events related to nuclear substances and prescribed equipment. Staff considered 167 of these to be reportable events. Notifications not considered reportable events may include such things as action level exceedances, successful fishing operations (well-logging), flooding where no nuclear substances or prescribed equipment have been affected, and potential work disruptions. Of the 167 reportable events, 164 were rated as level 0 (no safety significance) on the International Nuclear and Radiological Event Scale (INES) and 3 were rated as INES level 1 (anomaly). For all events reported, licensees implemented appropriate response measures to mitigate the impacts and to limit radiation exposure to workers and the public. CNSC staff reviewed the response measures and found them to be satisfactory. Figure 20 shows the 5-year trend for different types of events, tables 18 to 22 show event data by sector and subsector for each type of reportable event, and table 23 provides a summary of all reportable events. Additional information on reportable events is provided in section 6.0.

Appendix J: Safety performance rating levels

Table 28 explains the transition in the CNSC’s rating terminology. Some inspection reports still use the previous rating levels because of the licensing and compliance system in use, but licensees using nuclear substances and radiation devices can expect to see a gradual transition to the new ratings. For the purposes of reporting in this ROR, the previous rating levels have been converted to the new levels. The rating definitions below were updated in 2021 and endorsed by the CNSC management team. The fully satisfactory rating is no longer used.

Table 28: Transition in compliance rating terminology

Previous rating level	Description	New rating level	Description
A and B	Meets expectations	SA	Satisfactory
C	Improvement is required	BE	Below expectations
D	This area is seriously compromised
E	Breakdown	UA	Unacceptable

Satisfactory (SA)

Licensee meets all of the following criteria:

• Performance meets CNSC staff expectations.
• Licensee non-compliances or performance issues, if any, are not risk-significant.
• Any non-compliances or performance issues have been, or are being, adequately corrected.

Below expectations (BE)

One or more of the following criteria apply:

• Performance does not meet CNSC staff expectations.
• Licensee has risk-significant non-compliance(s) or performance issue(s).
• Non-compliances or performance issues are not being adequately corrected.

Unacceptable (UA)

One or both of the following criteria apply:

• The risk associated with a non-compliance or performance issue is unreasonable.
• At least one significant non-compliance or performance issue exists with no associated corrective action.
