REGDOC-2.10.1, Nuclear Emergency Preparedness and Response, Version 2

Preface

This regulatory document is part of the CNSC’s Emergency Management and Fire Protection series of regulatory documents. The full list of regulatory document series is included at the end of this document and can also be found on the CNSC’s website.

REGDOC-2.10.1, Nuclear Emergency Preparedness and Response, sets out the emergency preparedness requirements and guidance of the Canadian Nuclear Safety Commission (CNSC) related to the development of emergency measures for licensees and licence applicants of Class I nuclear facilities and uranium mines and mills to satisfy:

• the requirements of subsection 24(4) of the Nuclear Safety and Control Act, by demonstrating that the applicant will, in carrying on the proposed activity, make provision for the protection of the environment, the health and safety of persons, and the maintenance of national security and measures required to implement international obligations to which Canada has agreed
• paragraph 6(k) of the Class I Nuclear Facilities Regulations and subparagraph 3(c)(x) of the Uranium Mines and Mills Regulations

REGDOC-2.10.1 lists and discusses the requirements and guidance that licence applicants and licensees shall implement and consider in the design of their emergency preparedness program (EP program). EP programs are based on four components: planning basis; program management; response plan and procedures; and preparedness. These components are considered in the development of plans to prevent or mitigate the effects of accidental releases from a Class I nuclear facility or a uranium mine or mill.

REGDOC-2.10.1 is based on International Atomic Energy Agency (IAEA) guidance, and the following key IAEA documents were used in its development:

• Preparedness and Response for a Nuclear or Radiological Emergency, IAEA Safety Standards Series GS-R-2, Vienna, 2002
• Arrangements for Preparedness for a Nuclear or Radiological Emergency, IAEA Safety Standards Series GS-G-2.1, Vienna, 2007
• Preparation, Conduct and Evaluation of Exercises to Test Preparedness for a Nuclear or Radiological Emergency, EPR-Exercise, Vienna, 2005

Applicants and licensees may use these IAEA documents for further guidance, as required.

REGDOC-2.10.1 is intended to form part of the licensing basis for a regulated facility or activity within the scope of the document. It is intended for inclusion in licences as either part of the conditions and safety and control measures in a licence, or as part of the safety and control measures to be described in a licence application and the documents needed to support that application.

For proposed new facilities: This document will be used to assess new licence applications for reactor facilities.

Guidance contained in this document exists to inform the applicant, to elaborate further on requirements or to provide direction to licensees and applicants on how to meet requirements. It also provides more information about how CNSC staff evaluate specific problems or data during their review of licence applications. Licensees are expected to review and consider guidance; should they choose not to follow it, they should explain how their chosen alternate approach meets regulatory requirements.

For existing facilities: The requirements contained in this document do not apply unless they have been included, in whole or in part, in the licence or licensing basis.

A graded approach, commensurate with risk, may be defined and used when applying the requirements and guidance contained in this regulatory document. The use of a graded approach is not a relaxation of requirements. With a graded approach, the application of requirements is commensurate with the risks and particular characteristics of the facility or activity.

An applicant or licensee may put forward a case to demonstrate that the intent of a requirement is addressed by other means and demonstrated with supportable evidence.

The requirements and guidance in this document are consistent with modern national and international practices addressing issues and elements that control and enhance nuclear safety. In particular, they establish a modern, risk-informed approach to the categorization of accidents – one that considers a full spectrum of possible events, including events of greatest consequence to the public.

Other health, safety and environmental considerations may dictate adherence to additional requirements. It is the responsibility of licensees to identify any other applicable legislation or standards.

REGDOC-2.10.1 supersedes Regulatory Guide G-225, Emergency Planning at Class I Nuclear Facilities and Uranium Mines and Mills, published in 2001, as well as Regulatory Document RD-353, Testing the Implementation of Emergency Measures, published in 2008. It also fulfills a recommendation made by the CNSC Fukushima Task Force and the External Advisory Committee to strengthen licensees’ emergency preparedness programs.

1. Introduction

1.1 Purpose

REGDOC-2.10.1, Nuclear Emergency Preparedness and Response, sets out the emergency preparedness requirements and guidance of the Canadian Nuclear Safety Commission (CNSC) related to the development of emergency measures for licensees and licence applicants of Class I nuclear facilities and uranium mines and mills.

1.2 Scope

This regulatory document lists and discusses the components and supporting elements that CNSC licensees shall implement and consider when establishing an emergency preparedness program (EP program) to prepare for, to respond to, and to recover from the effects of accidental radiological/nuclear and/or hazardous substance releases from Class I nuclear facilities or uranium mines or mills. REGDOC-2.10.1 refers primarily to nuclear events, but the planning basis must also address releases of hazardous materials. In addition, REGDOC-2.10.1 addresses how licensees shall test the implementation measures of their EP programs through the conduct of exercises.

This regulatory document applies to all Class I nuclear facilities and uranium mines and mills. Some requirements in this document are specifically designated as applying only to nuclear power plants and research reactors with a thermal output capacity greater than 10 MW thermal.

An EP program should be developed in a manner that is commensurate with the complexity of the facility’s associated undertakings, as well as the probability and potential severity of the emergency scenarios associated with the operation of the licensed facility.

REGDOC-2.10.1 focuses on the aspects of emergency preparedness and response, while requirements for accident management are addressed in REGDOC-2.3.2, Accident Management, Version 2.

1.3 Accident management and its links with emergency preparedness and the principle of defence in depth for power reactors

An effective response to an emergency requires strong linkages between accident management and emergency preparedness. The fundamental premise underlying accident management is that the organization operating a nuclear reactor must be able to respond to any accident that cannot be practically eliminated in order to:

• prevent the escalation of the accident
• mitigate the consequences of the accident
• achieve a long-term safe stable state after the accident

Thus, accident management provides capability to respond to an accident within the reactor facility. It is important to recognize that accident management interfaces closely but is distinct from emergency preparedness, which provides emergency responses to mitigate the onsite and offsite impacts of an accident to workers and the public. Both accident management and emergency preparedness form part of the defence-in-depth provisions.

During a nuclear emergency, the practical goals of emergency response are:

• to regain control of the situation
• to prevent or mitigate consequences at the scene
• to prevent the occurrence of deterministic health effects in workers and the public
• to prevent, to the extent practicable, the occurrence of stochastic health effects in the population
• to prevent, to the extent practicable, the occurrence of non-radiological effects in individuals and among the population
• to render first aid and to manage the treatment of radiation injuries
• to protect, to the extent practicable, property and the environment
• to prepare, to the extent practicable, for the resumption of normal social and economic activity

The goals of emergency response are most likely to be achieved in accordance with the principles for intervention by having an effective EP program as part of the infrastructure for protection and safety. An effective EP program ensures that arrangements are in place to ensure a timely, coordinated and effective response to any emergency. It also helps to build confidence that an emergency response would be managed, controlled and coordinated.

Figure 1 illustrates links between the accident management, emergency preparedness and defence in depth. Accident management focuses on preventing an event that has already occurred from escalating and minimizing its radiological releases through use of various physical and procedural provisions. The specific provisions may vary depending on the accident (which may be a design basis accident or beyond design basis accident, including a severe accident). REGDOC-2.3.2, Accident Management, Version 2 provides complete descriptions of defence-in-depth levels and plant states.

An EP program establishes how nuclear facilities and other concerned organizations prepare for and plan to respond to emergencies (including nuclear or radiological emergencies, both onsite and offsite), in order to protect workers, the public and the environment.

1.4 Overview of Canada’s nuclear emergency management framework

Emergency management includes the prevention and mitigation, preparedness, response and recovery of nuclear emergencies.

Prevention of nuclear emergencies at Canadian nuclear facilities is the responsibility of the licensees. Through the authority of the Nuclear Safety and Control Act (NSCA), the CNSC regulates the Canadian nuclear industry in order to prevent unreasonable risk to the environment, the health and safety of persons, and national security. Mitigation of nuclear emergencies aims at ensuring that equipment, such as hydrogen recombiners, or procedures, such as emergency operating procedures, are put in place before a nuclear emergency to reduce the potential magnitude or impact of the hazard. Further information on accident management can be found in REGDOC-2.3.2, Accident Management, Version 2.

Preparedness relates to actions taken before a nuclear emergency in order to be ready to respond and manage its consequences, and includes the development of response procedures and plans, training workers, maintaining emergency facilities, exercises and fostering public awareness.

Response refers to those actions taken during a nuclear emergency, both onsite and offsite, to reduce the magnitude of the hazard and manage its consequences on health, safety and the environment. Response actions include protecting workers, supporting accident management activities, emergency public communication, emergency medical assistance, and shelter-in-place or evacuation.

Recovery includes the short-term and long-term actions taken both onsite and offsite in order to restore to an acceptable level both the organizations involved in and the communities affected by the nuclear emergency. The level of restoration would typically be determined by the responsible authorities, in consultation with the stakeholders affected by the nuclear emergency.

In Canada, the respective roles of the various levels of government in nuclear emergency preparedness and response are derived from legislated responsibilities. Provincial and territorial governments bear the primary responsibility for protecting public health and safety, property and the environment within their borders. The federal government regulates the peaceful use of nuclear energy in Canada, manages nuclear liability, and supports the responses of provinces to nuclear emergencies within their boundaries.

The federal government is also responsible for liaisons with the international community and diplomatic missions in Canada, for assisting Canadians abroad, and for coordinating Canada’s response to nuclear emergencies that occur in foreign countries, but that have an impact on Canada.

Under the administrative framework of the Federal Emergency Response Plan (FERP) and the Federal Nuclear Emergency Plan (FNEP), all levels of government, along with various agencies and organizations, have responsibilities for developing and implementing emergency plans to address nuclear emergencies with impacts outside the boundaries of CNSC-licensed nuclear facilities.

Guidelines for protective actions, such as Health Canada’s Canadian Guidelines for Intervention During a Nuclear Emergency and Canadian Guidelines for the Restriction of Radioactively Contaminated Food and Water Following a Nuclear Emergency, are intended to assist federal and provincial emergency response authorities on choosing appropriate protection actions to protect public health. Reference levels in these guidelines are used to inform decisions on what measures are necessary to protect the public during a nuclear emergency. These guidelines are based, in part, on advice from international organizations such as the IAEA and the ICRP and are found on Health Canada’s website.

1.5 Relevant legislation

The CNSC is the federal agency that regulates the use of nuclear energy and materials to protect health, safety, security and the environment, and to implement Canada's international commitments on the peaceful use of nuclear energy.

The NSCA requires persons and/or organizations to be licensed by the CNSC for carrying out the activities referred to in section 26. The regulations adopted under the NSCA stipulate requirements for CNSC licensing, as well as the obligations of licensees and workers.

One of the CNSC’s objectives is to regulate the development, production and use of nuclear energy and the production, possession and use of nuclear substances, prescribed equipment and prescribed information in order to prevent unreasonable risk to the environment and to the health and safety of persons, as well as unreasonable risk to national security, associated with that development, production, possession or use. To accomplish this, the CNSC has the authority to make regulations pursuant to section 44 of the NSCA.

Paragraph 3(1.1)(b) of the General Nuclear Safety and Control Regulations (GNSCR) states that the Commission may require any other information that is necessary to enable it to determine whether the applicant will make adequate provision for the protection of the environment, the health and safety of persons and the maintenance of national security and measures required to implement international obligations to which Canada has agreed. Sections 12 and 17 of the GNSCR place obligations on both licensees and workers to take all reasonable precautions to protect the environment and the health and safety of persons, and to maintain security of nuclear facilities and nuclear substances.

The Class I Nuclear Facilities Regulations and the Uranium Mines and Mills Regulations require licence applications to include information related to emergency planning. For instance, paragraph 6(k) of the Class I Nuclear Facilities Regulations and subparagraph 3(c)(x) of the Uranium Mines and Mills Regulations stipulate that an application for a licence to operate a Class I nuclear facility, or a general application for a licence in respect of a uranium mine or mill, shall describe the proposed measures to prevent or mitigate the effects of accidental releases of nuclear substances and hazardous substances on the environment, the health and safety of persons, and the maintenance of security, including measures to:

• assist offsite authorities in planning and preparing to limit the effects of an accidental release
• notify offsite authorities of an accidental release or the imminence of an accidental release
• report information to offsite authorities during and after an accidental release
• assist offsite authorities in dealing with the effects of an accidental release
• test the implementation of the measures to prevent or mitigate the effects of an accidental release

2. Emergency Preparedness Program

An effective EP program is based on the following four components:

1. Planning basis: an analysis of the risks and hazards that the EP program will address
2. Emergency response plan and procedures: a comprehensive description of how a response will be executed, with accompanying support material
3. Preparedness: the processes to ensure that people, equipment and infrastructure will be ready to execute a response according to the emergency response plan and procedures
4. Program management: the management system aspects that assure the effectiveness of the EP program

Licensed organizations with an existing EP program that address other corporate needs are encouraged to use this infrastructure to meet the requirements in this document.

Key components and overlapping provisions of emergency preparednes and accident management are illustrated in Appendix A.

2.1 Planning basis

All licensees shall:

1. establish a planning basis for their EP program
2. ensure the planning basis considers the hazards that have, or could have, an adverse impact on the environment and the health and safety of onsite personnel or the public, and also consider:
   1. all accidents and internal or external events that have been analyzed as having an unacceptable impact on their facilities
   2. the inclusion of multi-unit accidents scenarios for multi-unit power reactor facilities
   3. extended loss of power
3. use the results from the planning basis to determine the scope and depth of EP program requirements

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

4. provide regional and provincial offsite authorities with necessary information to allow for effective emergency planning policies and procedures to be established and modified, if needed, periodically

Guidance

Guidance for all licensees

A nuclear emergency may be caused by, or involve, different types of hazards, including natural incidents (e.g., flooding, tornadoes, tsunami, ice or snowstorms, forest fires) and equipment malfunctions (identified within the design basis and beyond design basis). All hazards that cannot be practically eliminated with possible initiating and propagating pathways should be identified within the planning basis. Response to criminal and malicious activity may be dealt with under a separate program.

The planning basis should be based on a full range of postulated scenarios that may challenge the facility’s emergency response capabilities. This should include scenarios that involve a nuclear or radiological emergency combined with a conventional emergency, such as an earthquake or forest fire. A detailed analysis may be used to determine scenarios that can be practically eliminated. Plans should be developed for those scenarios that cannot be practically eliminated. Inputs to be considered in the analysis should include: the licensee’s safety analysis, probabilistic safety analysis, and operating experience.

Additional guidance for licensees of reactor facilities with a thermal capacity greater than 10 MW

The information to be provided to regional and provincial offsite authorities should give all necessary details to make informed decisions on the size of emergency planning zones and the level of preparedness required. The necessary information should include:

• possible accidents that cannot be practically eliminated
• an estimate of the probability of such accidents occurring
• an estimate of the associated radiological consequences, including isotopic release quantities, possible release start time and duration and the geographical area potentially affected

Federal authorities would be provided emergency planning information through the CNSC.

2.2 Emergency response plan and procedures

All licensees shall develop and maintain emergency response (ER) plan(s) with supporting emergency response procedures. The ER plan shall be based on the planning basis as described in section 2.1 of this document. The ER plan shall identify and describe the methods that licensees use to respond to emergencies. This includes, but is not limited to, the following areas:

1. emergency response organization and staffing
2. emergency categorization, activation and notification
3. emergency assessment
4. offsite response organizations interface and support
5. emergency personnel protection
6. emergency response facilities and equipment
7. emergency information and public communications
8. recovery
9. validation of the ER plan and procedures

Guidance

Guidance for all licensees

The ER plan, which may consist of one or several documents, incorporates pertinent information directly or by reference. Plan content can vary to accommodate facility-specific needs and circumstances based on risk.

The ER plan may incorporate emergency preparedness and response procedures directly, or it may reference pertinent documents, such as the facility procedures manual(s). If referenced, the documents should be immediately accessible.

Procedures are used to define the necessary steps and/or requirements for various emergency preparedness and response processes and activities.

Licensees should also consult RD/GD-99.3, Public Information and Disclosure,concerning public disclosure protocols regarding events and developments at their facilities.

2.2.1 Emergency response organization and staffing

All licensees shall:

In accordance with the ER plan and procedures:

1. establish an emergency response organization (ERO) with a command structure that is clearly defined and integrated
2. define and document the minimum number of staff required to maintain the ERO and their qualifications
3. define the expected reporting times for the ERO to report to the emergency response facility or designated area (see section 2.2.6 of this document) after it has been alerted to respond
4. document the requirement to maintain and retain logs of all actions, orders, and track and update actions throughout the emergency

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

5. define and document how the ERO staffing will be maintained and monitored to ensure the minimum shift complement is available at the nuclear facility at all times
6. define and document how licensees will maintain the ERO extended response over multiple shifts

Guidance

Guidance for all licensees

An indication of an effective ERO is the demonstration of clear command and control over the emergency response. It should be clearly understood who is in charge and with whom final decisions and authorities lie. The ERO should be adaptable and flexible, so as to be able to manage an incident as it evolves or as its circumstances change rapidly or abruptly. Procedures should be in place to ensure:

• clear roles and responsibilities and authorities of each ERO position
• timely and adequate onsite and offsite communication
• periodic update and turnover briefings
• decisions documented in event logs
• effective and clear communication

Appropriate arrangements should be identified for shift turnover and provision of food and other amenities for prolonged duty caused by beyond design basis initiating events.

Additional guidance on the number of staff required to maintain the ERO and their qualifications can be found in CNSC regulatory document G-323, Ensuring the Presence of Sufficient Qualified Staff at Class I Nuclear Facilities – Minimum Staff Complement.

Licensees should also consult G-274, Security Programs for Category I or II Nuclear Material or Certain Nuclear Facilities, for further information regarding security aspects of emergency preparedness and response.

Additional guidance for licensees of reactor facilities with a thermal capacity greater than 10 MW

Members of mobile offsite survey teams need not be accounted for as part of the minimum complement for facilities equipped with real-time fixed radiological detection and monitoring capabilities, if the licensee makes provisions for immediate mobilization of offsite survey teams upon activation of the ERO.

Licensees should also consult REGDOC-2.12.1, High-Security Sites: Nuclear Response Force

2.2.2 Emergency categorization, activation and notification

All licensees shall:

Have an ER plan and procedures that:

1. describe the complete set of conditions that would require activation of the ERO
2. describe how unusual events, incidents and emergencies are to be determined and classified to initiate onsite response; the same notification categories and standard definitions used by offsite authorities shall be used and/or cross-referenced
3. describe the immediate notification process and secondary communication methods to alert all onsite personnel, to initiate personnel assembly and accounting, and to activate the ERO and associated emergency response and support facilities
4. define organizational methods, processes, timelines and emergency levels to notify the appropriate personnel and authorities
5. describe all offsite notification requirements and any time requirements that apply, ensuring that:
   1. the description includes identification of the appropriate positions, by title and agency, of the provincial, territorial and local government agencies
   2. offsite authorities are notified within 15 minutes of categorizing the event

Additional requirement for all Class I facilities: ensure the CNSC is notified within 15 minutes of activation of the ERO.

Guidance

Guidance for all licensees

Criteria that define when the ERO should be activated should be clearly documented.

Licensees should follow provincial requirements, or when none exist, use the following categories, listed in order of increasing significance, to categorize various events:

• reportable event: an event affecting the nuclear facility that would be of concern to the offsite authorities responsible for public safety
• abnormal incident: an abnormal occurrence at the nuclear facility that may have a significant cause and/or may lead to more serious consequences
• site area emergency: a serious malfunction that results or may result in an emission at a later time
• general emergency: an ongoing atmospheric emission of radioactive material, or one likely within a short time frame, as a result of a more severe accident

While item 5b above requires licensees to notify the offsite authorities within 15 minutes of event categorization, ideally such notification should be done as soon as possible. It is critical that the CNSC and offsite authorities be advised within the identified timeframes. The only acceptable exception to the requirement would be when immediate action was required to prevent a catastrophic incident from occurring.

2.2.3 Emergency assessment requirements

All licensees shall:

In accordance with ER plans and procedures:

1. describe the methods and procedures to continually assess the emergency and predict both onsite and offsite conditions and parameters
2. continuously take appropriate measures to protect onsite personnel
3. continually characterize the magnitude of the offsite risk to the public and the environment
4. continually provide updates on a regular basis to offsite authorities and the CNSC

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

5. have real-time fixed radiological detection and monitoring capabilities around the nuclear facility perimeter with appropriate backup power, and shall communicate results to offsite authorities and the CNSC
6. have sufficient capacity and capability for offsite radiological monitoring, including mobile offsite survey teams, and report results to the offsite response authorities and the CNSC
7. promptly and continuously assess and determine source term estimate, plume dispersion and dose modeling, and report results to the offsite authorities and the CNSC
8. promptly and continuously estimate dose to the public based on source term estimation, plume dispersion and dose modeling, and provide the dose estimates to offsite response authorities and the CNSC

Guidance

Guidance for all licensees

Emergency assessment, including categorization, is performed to determine:

• the onsite response and staff mobilization required to protect onsite personnel and equipment
• the notification category necessary for the provincial or territorial authorities to determine the required offsite response to protect the public and the environment

Licensees should describe the methods and procedures for continual assessment of the following pertinent conditions and parameters:

• the status, integrity and stability of the affected facilities and their components
• identification, quantities, concentrations, or release rates of radiation, contaminants or other hazardous substances
• onsite and offsite impacts on or threats to health, safety and the environment
• location and direction of radioactive plumes or other emissions
• loss of instrumentation

Additional guidance for licensees of reactor facilities with a thermal capacity greater than 10 MW

Source term sampling and estimation should be determined and reported to the CNSC on an hourly basis, upon determination and compilation of the data in a format approved by the provincial authority.

2.2.4 Interface and support for offsite response organizations

All licensees shall:

In accordance with ER plans and procedures:

1. establish plans and procedures to coordinate response activities with appropriate offsite organizations, in the event of an emergency with offsite implications
2. formally document any arrangements or agreements with other organizations or personnel
3. ensure that agreed-upon resources, and the quantity of these resources required to respond to offsite conditions, are available when needed
4. cooperate with and assist offsite organizations with their response activities to address offsite impacts; provide expertise and resources (personnel, emergency response equipment, and material) in support of offsite authorities during an emergency; and define the quantity of available resources within their ER plan
5. promptly and regularly provide recommendations to offsite authorities when protective action is required and inform the CNSC
6. establish what data is required and at what frequency, and make provisions to have nuclear facility data, and any other pertinent information that is determined as relevant to the emergency response, regularly transmitted to offsite authorities and the CNSC

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

7. incorporate the provincial or territorial emergency planning zone that is being used for plume exposure and ingestion pathways; the provincial or territorial plans shall be directly referenced
8. collaborate with the municipal or regional authorities to develop and maintain public evacuation time estimates based on current census data, and future population growth projections on a per-decade estimation until end of life of the facility
9. have, at all times, a designated onsite person with the authority and responsibility to categorize a nuclear emergency and to perform the following promptly and without consultation, upon categorization of the emergency:
   1. initiate an appropriate onsite response
   2. notify the appropriate offsite authorities
   3. provide sufficient information for an effective offsite response
10. provide the designated person with a suitable means of alerting onsite response personnel and notifying the offsite notification point
11. for NPPs, ensure there is a designated person onsite at all times with the authority for venting
12. for NPPs, ensure that offsite authorities and the CNSC are consulted before undertaking any venting activity, unless venting must be performed in an urgent manner to protect the structural integrity of containment; in such a case, every effort shall be made to inform the offsite authorities and the CNSC as early as possible^{Footnote 1}
13. include, in each report to the CNSC and offsite authorities, estimates of when venting will be required
14. notify the province and the CNSC of all abnormal incidents as described in section 2.2.2

Guidance

Guidance for all licensees

Licensees should identify the jurisdictions, organizations or persons that could be formally involved in emergency preparedness and response activities pertaining to facility emergencies with offsite impacts, and then develop mutual aid and community agreements where appropriate.

During an emergency it is critical to have an onsite person with the required authority to order emergency venting if required. However, this authority can be delegated if it is impractical to have a senior emergency officer onsite at all times.

The ER plan should also define a clear and concise strategy for communications between onsite and offsite organizations. All communications, including event data and the decisions made throughout the emergency response, should be documented and recorded. While the licensee is required to provide recommendations to offsite authorities, it is at the discretion of the authorities to accept, reject or modify recommendations.

The nuclear emergency response plans for offsite response organizations (those of provinces and municipalities as well as firefighters, emergency medical services personnel and police) should be included with licence application documents for licence renewal and new applications.

2.2.5 Emergency personnel protection

All licensees shall:

In accordance with ER plans and procedures:

1. develop and document emergency radiation protection measures that align with their radiation protection program

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

2. have sufficient personal protective equipment (PPE) and provisions to respond to emergencies and protect the emergency responders for the first 72 hours without offsite assistance
3. maintain sufficient PPE and response equipment, calibrated and poised for immediate use in an emergency; the type and amount of PPE and defined emergency response equipment shall be based on criteria for design-basis accidents and beyond-design-basis accidents

Guidance

Additional guidance for licensees of reactor facilities with a thermal capacity greater than 10 MW

Licensees should be able to manage the first 72 hours of an emergency response without offsite support, in case outside assistance is unavailable. Remotely located facilities (such as those on northern sites) may experience significant emergency response delays because of effects such as severe weather. In such cases, licensees should demonstrate how their ER plans have accounted for the possibility that offsite assistance may not be available for extended periods of time.

Electronic dosimeters should be calibrated, poised and immediately available for designated emergency work. Systems used for maintaining, reading and charging these dosimeters should be in working condition at all times. For battery-operated equipment, sufficient numbers of batteries should be available. Backup facilities and emergency response equipment needed to maintain equipment for electronic dosimeters, radiation instrumentation and laboratory services should be referenced within the ER plan.

Emergency protective provisions may include, but are not limited to:

• establishing or designating areas for the emergency assembly of site personnel
• ensuring that assembly areas are located in areas that can be accessed safely during emergencies
• ensuring that there are alternate safe access routes to radiation instrumentation and electronic dosimeters, in addition to assembly areas and PPE during emergencies
• accounting for site personnel and all other persons on site (contractors, visitors, etc.); all onsite staff should be able to be accounted for within 30 minutes; accounting should be commensurate with the scale/categorization of the emergency
• using dose records to assign specific emergency response tasks
• ensuring offsite emergency responders have access to radiation protection assistance from onsite personnel
• implementing special administrative measures, such as action levels to control radiation doses
• conducting radiation surveys and radioactive contamination monitoring
• monitoring and tracking of radiation doses
• implementing back-out dose limits and protective actions when emergency action levels are exceeded through pre-set electronic personnel dosimeter alarms
• providing search and rescue, decontamination and first aid services
• providing dosimetry and any other emergency response equipment, instruments, materials, facilities and services necessary to ensure that onsite and offsite personnel are protected
• ensuring appropriate radiological and hazardous substances protection and information are provided to all emergency responders, including those from external organizations providing onsite support
• ensuring that PPE, electronic dosimeters and radiation survey meters / radiation instrumentation are appropriate for their intended use
• interfacing with offsite responders (e.g., ambulance attendants and hospital staff) to ensure that pertinent hazardous material and radiological information is provided to medical staff
• providing thyroid-blocking agents (potassium iodide pills) when applicable
• briefing, tracking, and debriefing the dispatched teams on safety requirements, communication requirements, etc.; emergency response personnel’s briefing should include personal safety requirements and a three-way communication strategy
• continued verification of the habitability of all emergency response facilities, including monitoring for radiation fields and hazardous materials, where appropriate

This document does not address shift turnover. Additional guidance on shift turnover can be found in CNSC Regulatory Document G-323, Ensuring the Presence of Sufficient Qualified Staff at Class I Nuclear Facilities – Minimum Staff Complement.

2.2.6 Emergency response facilities and equipment

All licensees shall:

In accordance with ER plans and procedures:

1. identify an onsite emergency response facility or designated area to be used as a response location
2. identify essential emergency response equipment, and describe how its operation and effectiveness during emergencies are assured; essential emergency response equipment includes equipment required to detect and assess hazards, and communicate response activities
3. identify and have emergency response equipment and materials that are operational and available in sufficient quantities for an extended multi-shift response; they shall also be readily accessible during emergency conditions

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

4. have an emergency response facility (ERF) located onsite, but outside of the protected area; if this cannot be achieved, describe security arrangements to prevent nuisance actors from interfering with emergency response, and provisions for alternate means of communication in the event of a total communications blackout
5. have an emergency response facility located offsite and outside of the plume exposure planning zone
6. ensure that the emergency response facilities will ensure the health and safety of workers in the ERF and ensure the continuity of operations for all emergency situations that cannot be practically eliminated (if this cannot be achieved, then have backup facility with similar capability for each of the onsite and offsite such that the backup facility is unlikely to be effected by an event that would disable the primary; in addition, activation or transfer of operations to the backup facility must be done without disruption to the response operations)
7. provide a workspace with computer, internet access and telephone for a CNSC representative in each ERF; in addition, the CNSC shall be granted access to install an antenna for a satellite phone at each ERF
8. ensure all emergency response facilities have the capacity and capability of sustaining emergency response for a minimum of 72 hours without offsite support
9. ensure the design and layout of emergency response facilities are able to support the emergency response
10. ensure emergency response facilities have provisions in place to provide nuclear facility data
11. pre-arrange memoranda of understanding and/or other priority services agreements required to keep ERFs functional over prolonged periods, and ensure such agreements are documented and either referenced or attached to the ER plan
12. determine and implement methods for communicating with onsite personnel and offsite authorities, including the implementation of at least two levels of backup communications systems; licensee communication links must be compatible with the licensee, province or territory, and the CNSC

Additional guidance for licensees of reactor facilities with a thermal capacity greater than 10 MW

The CNSC workspace should have appropriate resources (such as computers, information access, internet access and satellite phones) to enable CNSC representatives to perform their functions adequately.

The preferred means of ensuring the protection of workers and the continuation of operation is to have hardened facilities within the primary zone that have:

• radiological protection/shielding
• adequate ventilation,
• contamination control
• the ability to withstand design-basis event hazards, such as wind, tornado, snow or ice

2.2.7 Public emergency information

All licensees shall:

In accordance with ER plans and procedures:

1. provide information about the emergency to offsite authorities during the emergency response and recovery phases
2. coordinate with offsite authorities when communicating emergency information to the public

Guidance

Guidance for all licensees

In the emergency plan, licensees should describe the procedures to communicate information about the emergency to offsite authorities during emergencies. These procedures should ensure that emergency information is sent routinely – and as conditions change (either positively or negatively) – to offsite authorities so the information can be disseminated to the public.

The information communicated to offsite authorities should include possible radiological and non-radiological hazard(s), including their short-term effects as well as their potential long-term effects on the public, for all emergency scenarios.

In the emergency plan, licensees should describe the protocols to ensure coordinated public communications during an emergency. For nuclear power plants, provisions should include consideration of communications strategies and describe the roles and responsibilities of organizations that are responsible for communicating key information to the public.

2.2.8 Recovery

All licensees shall:

In accordance with ER plans and procedures:

1. describe the process to transition from emergency response to recovery after the termination of an emergency, including the requirements to establish a recovery organization and to develop a recovery plan
2. identify, in the recovery plan, the positions/titles, authorities and responsibilities of the individuals who will fill key positions in the recovery organization; this organization shall also include technical personnel with responsibilities to develop, evaluate and direct recovery and reentry operations

Guidance

Guidance for all licensees

A conceptual and strategic recovery plan should be prepared in advance. This can act as the basis for developing the recovery plan after the event has occurred and the emergency phase is complete.

The recovery plan should:

• identify and describe the resources (personnel, facilities and emergency response equipment) that are to be available for recovery purposes
• describe how personnel will be protected when assessing or implementing the recovery program (e.g., personnel protection measures for entry into hazardous areas)
• provide for post-accident assessments of the causes, details, impacts and/or consequences of the events
• ensure all recovery efforts operate in accordance with the licensee’s operating licence requirements

Once the emergency phase of an emergency response has ended, workers undertaking recovery operations (such as repairs to plant and buildings, waste disposal or decontamination of the site and surrounding area) are subject to the occupational dose limits listed in the CNSC’s Radiation Protection Regulations.

2.2.9 Validation of the emergency response plan and procedures

All licensees shall:

1. validate ER plans and procedures to demonstrate that systems as designed (equipment, procedures and personnel elements) meet performance requirements and support safe operation
2. validate any changes to ER plans or procedures before implementing them, to ensure continued effectiveness
3. unless otherwise specified in the licence conditions handbook, notify the CNSC of changes to ER plans and procedures, and submit the results of the validation to the CNSC as per the terms and conditions of the CNSC licence

Guidance

Guidance for all licensees

For the purpose of this section, “change” means an action that results in modification to, addition to, or removal from a licensee’s ER plan. All changes should be validated to demonstrate that performance requirements are met and to determine if there has been a reduction in effectiveness (i.e., decreased capability to respond to an emergency).

A licensee may make changes to its ER plan(s) and procedures without CNSC approval, but only if it performs and retains an analysis that demonstrates that the changes have not reduced the ER plan’s effectiveness. This analysis must also demonstrate that plans continue to meet operating licence requirements as well as regulatory requirements.

A change to a licensee’s ER plan and procedures that reduces the effectiveness of the plan is not to be implemented without prior acceptance by the CNSC. A licensee desiring to make such a change should submit an application for change approval to the CNSC; the request should include the revised ER plan and demonstration of validation. The CNSC will have 30 days to review a change request, after which it will inform the licensee if the change has been accepted. The CNSC is unlikely to permit changes that would decrease an ER plan’s effectiveness; however, under special circumstances (e.g., construction or temporary facility modifications), such changes may be approved with specific conditions. Under no circumstances would the CNSC allow a licensee to implement changes that would compromise safety or lead to unreasonable risk.

Minor or administrative modifications to programs or procedures can be reported to the CNSC through established channels such as the Quarterly Operations Report or through formal correspondence.

2.3 Preparedness

Preparedness consists of activities to ensure that people, equipment and infrastructure will be ready to respond to an emergency, in accordance with the ER plan and procedures.

2.3.1 Training and qualification

All licensees shall:

In accordance with training and qualification:

1. collaborate with responding offsite agencies to educate them on radiation protection

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

2. develop and submit emergency drill and exercise schedules annually to the CNSC
3. train and qualify all emergency response organizations (EROs) in accordance with the positions to which they have been assigned; educational materials are required to be available for any person who would be responding to the emergency on behalf of an offsite authority, not just the first responders
4. establish requirements for frequency of re-qualification training for all ERO positions

Guidance

Guidance for all licensees

Licensees should provide necessary training to individuals and/or organizational units to assure and demonstrate they are qualified and able to completely fulfill their assigned emergency response roles. The training is intended for any person who would be responding to the emergency on behalf of an offsite authority and is not solely limited to first responders.

ERO training may consist of both formal and informal instruction (including workplace and classroom instruction). Licensees can also develop and use online training materials. Emergency drills are an additional option. Typical attributes of an emergency drill include:

• limited scope
• limited number of personnel
• specific equipment
• timely feedback
• realistic environment

An emergency drill typically involves testing a procedural or physical component of the emergency response program. An emergency drill may be conducted as an initial or periodic test, as a supervised training session or as an evaluation of a remedial event. For example, after steps are taken to correct a weakness identified by an emergency exercise, a drill may be held to further evaluate the effectiveness of the remedial measures.

Licensees should describe the following:

• initial and continuing training programs for EROs
• ERO staff qualifications
• ERO positions for which incumbents will be required to undertake periodic or on-going training
• training requirements for contractors and offsite organizations (e.g., firefighters, police personnel, ambulance drivers, hospital staff) that support or participate in onsite activities – insofar as these requirements relate to training that is outside their typical professional duties, but that is required for responding to onsite emergencies; such training could address subjects like access requirements or radiation protection
• schedules, procedures and assessment criteria for the conduct of emergency drills and exercises
• positions responsible for managing, planning, controlling and evaluating drills

Personnel assigned to emergency response roles should demonstrate and maintain their capability to perform assigned tasks at all times. Drills should include the use of all procedures, PPE, response equipment and facilities that could be required during an actual emergency.

Requirements and guidance for training systems can be found in REGDOC-2.2.2, Personnel Training.

2.3.2 Maintenance of emergency response facilities and equipment

All licensees shall:

Identify and implement requirements and provisions to assure that the necessary emergency response facilities, equipment, and materials are maintained and in working condition at all times. However, facilities and equipment may be taken out of service for required maintenance if alternate provisions are put in place during these periods.

Guidance

Guidance for all licensees

Emergency response facilities, equipment and materials must be in a state of readiness at all times. Accordingly, licensees should implement provisions to ensure that such equipment, facilities and materials are always in working condition. These provisions are to include regular inspection, calibration, testing, and maintenance, or replacement as required, within formal systems of quality control and inventory control and accounting. This criterion includes all required PPE.

2.3.3 Testing the implementation of emergency measures

• test the implementation of their emergency measures

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

1. perform exercises to test the effectiveness of their EP program
2. ensure emergency exercises are based on their planning basis; for multi-unit nuclear reactor facilities, licensees must ensure that multiple-unit emergency exercises are part of their exercise repertoire
3. establish specific objectives for each emergency exercise; the type and number of objectives will depend on the size of the facility and the scope of the exercise
4. design exercise objectives to sufficiently challenge their capability and capacity to respond to emergencies
5. include provisions in emergency exercise objectives for:
   1. assessment
   2. protection of facility personnel
   3. protection of the public and the environment
   4. termination of an emergency
   5. adequacy and conduct of exercises
6. test all requirements listed in this document over a five-year period, with a full-scale integrated emergency testing exercise at least once every three years involving, at a minimum, regional and provincial offsite authorities
7. submit emergency exercise objectives, team organization and scenario development framework to the CNSC at least 20 business days before conducting full-scale emergency exercises (in case of operational requirements and factors beyond licensee control, changes can be made up to the day of the exercise)
8. execute exercises that will meet all stated objectives, demonstrate thorough planning, and identify weaknesses and deficiencies so they can be prioritized and corrected; and provide an overall accurate indication of their emergency response capabilities
9. demonstrate sound organizational and professional execution in the conduct of the exercises by:
   1. keeping exercise scenarios unknown to the emergency responders before exercises are conducted
   2. providing timely and realistic data, messages and materials
   3. having exercise participants demonstrate realistic and professional behavior for simulated actions
10. ensure persons perform their required tasks during exercises as though actual emergency conditions were present
11. staff and train exercise controllers and evaluators to control and evaluate exercises, and provide them with exercise materials that include:
    1. instructions about how to conduct exercises
    2. exercise evaluation criteria
12. provide direction pertaining to existing requirements for safety and security measures adhere to applicable regulations and licence conditions during exercises, ensuring all participants are aware of the actions and interventions that are not permitted while exercises are in progress
13. provide feedback after exercises to improve their overall ability to respond effectively to emergencies
14. prepare self-assessment reports regarding the execution of full-scale emergency exercises; such reports must be submitted to the CNSC 40 days after exercises have been conducted (in exigent circumstances, reports could be delayed to no later than 90 days following the conclusion of exercises)

Guidance

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW. These licensees shall:

Emergency exercises test the adequacy of EP programs and the implementation of emergency measures. This includes an evaluation of the adequacy of the procedures and training of the ERO to respond to an emergency.

Emergency exercises simulate emergency events and conditions over a minimum of several hours, in order to test the integrated performance of the EP program. Emergency exercises simultaneously measure and demonstrate: the preparedness and competence of participants in the specific emergency response roles, the quality of the associated procedures, and the effectiveness of the administrative framework. Exercises designed with a high degree of fidelity ensure that the performance observed could be reasonably expected during an actual event. Deficiencies that are identified during emergency exercises should be rectified as soon as possible, to provide assurance that the ER plan and procedures can and will be implemented successfully in the event of an emergency.

Typical attributes of an emergency exercise include:

• mobilization of emergency equipment and resources in a realistic environment over an extended period of time
• demonstration of inter-agency and other government department cooperation
• testing of communication systems and/or public information systems
• testing of emergency response facilities and equipment readiness
• conduct of the exercise with the minimum complement numbers of staff, in order to demonstrate adequacy of the response
• criteria to terminate the exercise that are established ahead of time, in order to ensure that all of the required actions are completed
• success criteria that are established during the planning phase, and a corresponding evaluation of performance during the exercise

A full-scale integrated exercise tests the capacity of onsite and offsite agencies to respond to an emergency that results in a release of nuclear substances from the affected unit(s). Full-scale emergency exercises involve, at minimum, several onsite and provincial and regional offsite stakeholders. Larger full-scale exercises can include federal and – where appropriate – international authorities and agencies. Emergency exercises do not always need to be full-scale. For example, tabletop emergency exercises, such as those for notification and communications, may be sufficient to stimulate discussion of various issues regarding a hypothetical emergency.

Emergency exercises should not be used as part of a participant’s training development. Participation in an exercise is not meant to evaluate an individual’s competency, but rather is intended to assess the adequacy of an EP program and its implementation. Coaching and training should not be provided to participants in exercises by controllers or evaluators. Exercises should be conducted in accordance with the minimum requirements of the ER plan.

Self-assessment reports should contain the following information:

• success and failures of exercise drills
• lessons learned
• areas for improvement
• corrective action plans

2.3.4 Public preparedness requirements

All licensees shall:

Incorporate information on public emergency preparedness into their public information program (established as per RD/GD-99.3, Public Information and Disclosure) to ensure information on emergency preparedness and response is communicated to surrounding communities and stakeholders.

Additional requirements for licensees of reactor facilities with a thermal capacity greater than 10 MW and with designated offsite emergency planning zones.

These licensees shall provide the necessary resources and support to provincial and municipal authorities in implementing the provincial and municipal plans to do the following, or shall do the following:

1. ensure that a sufficient quantity of iodine thyroid-blocking (ITB) agents is pre-distributed, to all residences, businesses and institutions within the designated plume exposure planning zone, together with instructions on their proper administration
2. ensure that a sufficient quantity of ITB agent is pre-stocked and available within the designated ingestion control planning zone; this inventory of ITB agents shall be located so that it can be efficiently obtained by, or provided to, members of the public when required
3. ensure that ITB agents can be obtained by residents of the designated ingestion control planning zone at any time
4. ensure that particular consideration is given to sensitive populations such as children and pregnant women within the designated ingestion control planning zone
5. ensure that the pre-distributed and pre-stocked ITB agents are maintained within expiry date
6. ensure that the pre-distribution plans are supported by a robust, ongoing, and cyclical public education program
7. ensure that all residences, businesses and institutions within the designated plume exposure planning zone are provided with public emergency preparedness information detailing how they should prepare for a nuclear emergency and what they should do or expect during a nuclear emergency; this information will reinforce the public education program designed to support the pre-distribution of ITB agents
8. ensure that this public emergency preparedness information is readily available to the general public, including online

Guidance

Guidance for all licensees

Licensees may, where possible, leverage existing communication channels (such as those used by local municipalities or those identified in their public information program as per RD/GD-99.3, Public Information and Disclosure).

Licensees should periodically assess the adequacy of public emergency preparedness information.

Additional guidance for licensees of reactor facilities with a thermal capacity greater than 10 MW

For reactor facilities with a thermal capacity greater than 10 MW and with designated offsite emergency planning zones:

The term ITB agent is used generically and includes potassium iodide (KI) tablets.

The pre-distribution of ITB agents should be undertaken by representatives of the health and/or emergency management authorities of the province or region/municipality, with support from the licensee. The pre-distribution of ITB agents should be done in a carefully planned and coordinated manner, to ensure that the public receives the appropriate information and education related to the benefits, risks and usage instructions of ITB agents.

Pre-stocked ITB agents for the designated ingestion control planning zone should be located to facilitate prompt and efficient distribution during an emergency. Recognizable locations with credible persons within the community (such as fire stations, police stations and pharmacies) should be considered in the selection of pre-stocking locations.

Following the completion of pre-distribution activities, periodic reviews with the local populations to assess the adequacy of pre-distribution programs should be performed.

The term “designated plume exposure planning zone” is sometimes referred to as “primary zone”, “urgent protective action zone” or “emergency planning zone”. The size of the plume exposure planning zone is determined by the appropriate offsite authorities based on information in the planning basis and is typically sized in the range of 8 to 16 km.

The term “designated ingestion control planning zone” is sometimes referred to as “secondary zone”, “extended planning distance” or “ingestion planning zone”. Appropriate offsite authorities determine the size of the ingestion control planning zone (typically in the range of 50 to 80 km) based on information in the planning basis.

To ensure the public have easy access to the required emergency preparedness information, licensees should collaborate with municipalities to provide residents with useful information on how they should prepare, what they should expect and how they should respond to an emergency at the nuclear facility.

An emergency preparedness information product should be distributed in hard copy annually to every residence, business and institution within the plume exposure planning zone, and posted on a variety of websites, including those of the licensees, municipalities and provincial EMOs.

This should include information on:

• how they will be alerted
• how they will be notified or informed on what to do
• sheltering-in-place instructions
• evacuation orders
• how/when to take ITB agents, and where to get them if not pre-distributed
• contact details for where to obtain additional information, such as websites and social media sites

Licensees may, where possible, leverage existing communication channels (such as those used by local municipalities or those identified in the public information program).

In discussion with local authorities, licensees should consider providing public preparedness information with ITB packages when distributing to local populations.

2.4 Program management

All licensees shall:

Include, at a minimum, the following elements in their management systems:

1. a written policy statement issued by licensee senior management, committing all units of the organization to the system and its effective implementation
2. a program owner identified with the authority to ensure that resources are given to all aspects of the EP program
3. procedures describing the planned and systematic actions necessary to provide adequate confidence that all specified requirements are satisfied
4. procedures that specify who (position or unit) is to review and update the program on an ongoing basis, and how this is to be done
5. review and update EP program and associated documentation (e.g., response plan, training material, procedures, etc.) at defined intervals to take into account relevant factors, such as operating experience, changing needs or circumstances, and lessons learned from real events

Guidance

Guidance for all licensees

The EP program should be managed as part of a facility’s overall management system. A management system is generally defined as a set of interrelated or interacting elements that establish policies and objectives, and that enables those objectives to be achieved safely, efficiently and effectively. The management system brings together the processes needed to satisfy EP program requirements in a planned and integrated manner.

The management system’s requirements primarily aim to ensure that safety is not compromised, by considering the implications of all actions with regard to safety as a whole. Safety should be the paramount consideration, guiding decisions and actions, in the establishment of a management system.

As stated in their licences and licence conditions handbooks, licensees should:

• manage their EP programs in accordance with management system requirements
• detect and report deficiencies, and ensure all corrective actions are tracked and implemented as per management system requirements
