This regulatory document clarifies requirements and provides guidance for applicants and licensees on how to demonstrate the safety of a Class IB nuclear facility, including information relating to: • the safety analysis program (the managed process that governs the conduct of a safety analysis) • the conduct of a safety analysis (the systematic evaluation of the potential hazards) • safety analysis documents, records and reporting

This regulatory document sets out the requirements of the Canadian Nuclear Safety Commission (CNSC) with regard to maintenance programs for nuclear power plants (NPPs). This document also provides information and guidance on how the requirements may be met. When incorporated into a licence or other legally enforceable instrument, this regulatory document becomes a legal requirement.

This regulatory document sets out the requirements of the Canadian Nuclear Safety Commission (CNSC) for the design of new water-cooled nuclear power plants. It establishes a set of comprehensive design requirements and guidance that are risk-informed and align with accepted national and international codes and practices.

This regulatory document sets out the requirements of the Canadian Nuclear Safety Commission (CNSC) for deterministic safety analysis for nuclear power plants (NPPs) and small reactor facilities.

This regulatory document sets out requirements for nuclear criticality safety and provides guidance on how those requirements may be met. It provides information for the prevention of criticality accidents in the handling, storage, processing, and transportation of fissionable materials and the long-term management of nuclear waste.

REGDOC-2.13.1, Safeguards and Nuclear Material Accountancy, sets out CNSC requirements and guidance for the establishment and maintenance of a safeguards program.

Regulatory document REGDOC-2.3.4, Operations Programs for Reactor Facilities, clarifies the requirements for, and provides guidance on, developing and implementing operations programs for reactor facilities (nuclear power plants, advanced reactor designs and small modular reactors). This regulatory document is based on operational experience (OPEX) and best practices developed from water-cooled nuclear power plants. This information will be updated as additional information is gathered from advanced reactor designs and small modular reactors. Proponents, applicants and licensees of advanced reactor designs and small modular reactors should apply the information and concepts from this regulatory document to the extent practicable and as best applicable to that design.

Environmental protection for nuclear facilities and activities is done in accordance with the Nuclear Safety and Control Act (NSCA) and the regulations made under the NSCA. This legislation includes provisions to ensure that licensees are meeting the CNSC’s mandate to protect the environment and the health, safety and security of persons. The CNSC requires the environmental effects of all nuclear facilities or activities to be considered and evaluated when licensing decisions are made. This regulatory document provides information to applicants and licensees on protecting the environment and the health of persons, including: - identification of facility or activity interactions with the environment and the public - identification and mitigation of potential environmental effects associated with these interactions - design and implementation of effluent and emission release measures and of the environmental monitoring measures to confirm or test the predictions and the actual effects - periodic assessments of the environmental protection measures and the licensee’s performance In particular, this regulatory document describes: - the CNSC’s principles for environmental protection - for all nuclear facilities or activities that interact with the environment, the scope of an environmental assessment (EA) and the roles and responsibilities associated with an EA - the CNSC’s requirements and guidance to applicants and licensees for developing environmental protection measures, including an environmental risk assessment (ERA) where required, for both new and existing facilities or activities

This regulatory document consolidates the requirements and guidance of the Canadian Nuclear Safety Commission (CNSC) for reports and, notifications to and the filing of specific records with the CNSC by licensees of nuclear power plants (NPPs), as well as the applicable time frames for reporting. Licensees are required to report to or notify the CNSC of situations, events, or dangerous occurrences that may require short-term action by the CNSC. They are also required to submit or file other reports, notifications or specific records, including routine scheduled reports on various topics such as certain normal business activities that are required for action by the CNSC, or that are required for longer-term compliance monitoring.

This regulatory document provides guidance and clarity on requirements for the application of the RPR. This regulatory document will help ensure that licensees implement adequate measures for radiation protection in accordance with the Nuclear Safety and Control Act (NSCA, the Act) and the RPR. This regulatory document is intended for use by CNSC licensees and applicants
