The Canadian Nuclear Safety Commission (CNSC) has published REGDOC-2.4.1, Deterministic Safety Analysis, and REGDOC-2.4.2, Probabilistic Safety Assessment (PSA) for Nuclear Power Plants.
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 CNSC's regulatory framework. Deterministic Safety Analysis and Probabilistic Safety Assessment (PSA) for Nuclear Power Plants include targeted amendments to existing requirements, to address the lessons learned from the Fukushima event.
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. For more information, see the REGDOC-2.4.1 Web page.
REGDOC-2.4.2, Probabilistic Safety Assessment (PSA) for Nuclear Power Plants, sets out requirements for conducting a PSA that provides a comprehensive and integrated assessment of the safety of a reactor facility. As a result of additional feedback from stakeholders, guidance has been included to clarify the intent of certain requirements. For more information, see the REGDOC-2.4.2 Web page.
The CNSC regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; to implement Canada's international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
