Summary
Regulatory document REGDOC-2.4.1, Deterministic Safety Analysis, sets out requirements and guidance for the preparation and presentation of a safety analysis, including the selection of events to be analyzed, acceptance criteria, safety analysis methods, and safety analysis documentation, to demonstrate the safety of a nuclear facility.
The CNSC's Fukushima Task Force Report and the CNSC Integrated Action Plan on the lessons learned from the Fukushima Daiichi nuclear accident identified improvements to existing regulatory documents to strengthen the regulatory framework. REGDOC-2.4.1includes targeted amendments to existing requirements that are specified in regulatory documents RD-310, Safety Analysis for Nuclear Power Plants, and RD-308, Deterministic Safety Analysis for Small Reactor Facilities, to address the lessons learned from the Fukushima event.
This document includes content from GD-310, Guidance on Safety Analysis for Nuclear Power Plants, published in March 2012, which already included changes driven by the lessons from the Fukushima accident. As a result, the existing content has been integrated into REGDOC-2.4.1.
This document is part of the Safety Analysis series of the CNSC's regulatory framework. Other documents in this series are REGDOC-2.4.2, Probabilistic Safety Assessment (PSA) for Nuclear Power Plants (published in May 2014) and RD-327, Nuclear Criticality Safety (December 2010).
REGDOC-2.4.1 supersedes:
- RD-310, Safety Analysis for Nuclear Power Plants (February 2008)
- RD-308, Deterministic Safety Analysis for Small Reactor Facilities (June 2011)
- GD-310, Guidance on Safety Analysis for Nuclear Power Plants (March 2012)
Status: published May 2014
