This document sets out the CNSC’s requirements and guidance for anyone who intends to import or export nuclear and nuclear-related dual-use items, also known as controlled nuclear substances, equipment and information.

Regulatory document REGDOC-1.6.2, Developing and Implementing an Effective Radiation Protection Program for Nuclear Substances and Radiation Devices Licences provides guidance to nuclear substances and radiation devices licensees and applicants on the development, implementation, management and assessment of their radiation protection programs.

Canada’s Packaging and Transport of Nuclear Substances Regulations, 2015 (PTNSR 2015) are based on the regulations established by the International Atomic Energy Agency (IAEA): SSR-6, Regulations for the Safe Transport of Radioactive Material, 2018 edition (IAEA Regulations) [1]. All IAEA Member States follow the IAEA Regulations, which assure consistent, safe practices internationally.The PTNSR 2015 introduce an ambulatory reference to the IAEA Regulations and no longer explicitly identify and list relevant paragraphs from the IAEA Regulations. This change ensures that Canadian regulations will continue to align with international regulations, if international regulations are modified.

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

Part A of regulatory document REGDOC-2.12.3, Security of Nuclear Substances: Sealed Sources and Category I, II and III Nuclear Material, Version 2, sets out the minimum security measures that licensees must implement to prevent the loss, sabotage, illegal use, illegal possession or illegal removal of sealed sources during their entire lifecycle, including while they are in storage or transport, or being stored during transportation. If third-party carriers are used to transport radioactive material, this document also sets out the minimum security measures that a licensee must ensure a carrier of sealed sources complies with while the sealed sources are in transport or being stored during transportation.Part B of this document sets out guidance to help applicants prepare and submit the security information to be included with an application for a licence in respect of Category I or II nuclear material or a nuclear facility. It also provides guidance for applicants to prepare a “written transportation security plan” with respect to a licence to transport Category I, II or III nuclear material.

For nuclear facilities and activities, environmental protection is done in accordance with the Nuclear Safety and Control Act (NSCA) and the regulations made under it. The legislation includes provisions to ensure that licensees are meeting the CNSC’s mandate to protect health, safety and security and the environment. Under the NSCA and its regulations, licensees are required to take all reasonable precautions to control the release of nuclear and hazardous substances to the environment from licensed facilities or activities. As part of an application for a licence to construct, operate or decommission a nuclear facility, applicants and licensees are required to assess the effects on the environment and the health and safety of persons, and identify prevention or mitigation measures. In addition, the application must identify the: • proposed location(s) of releases • proposed maximum quantities and concentrations • anticipated volume and flow rate of releases of nuclear and hazardous substances into the environment • proposed measures to control releases of nuclear substances and hazardous substances into the environment This regulatory document describes the requirements and guidance for controlling releases to the environment, through: • applying the concept of best available technology and techniques economically achievable (BATEA) • implementing licensed release limits and action levels for releases to the environment • commissioning a treatment system and confirming performance • implementing adaptive management where require

This document provides information about making, receiving, reviewing, appealing and redetermining orders pursuant to the Nuclear Safety and Control Act (NSCA) and its regulations.

This regulatory document sets out requirements and guidance for reports and notifications that licensees of waste nuclear substances, Class II nuclear facilities and users of prescribed equipment, nuclear substances and radiation devices must submit to the Canadian Nuclear Safety Commission (CNSC). This document also presents the types of reports and the applicable timeframe for reporting. Licensees and those who transport nuclear substances are required to report to the CNSC regarding situations, events and dangerous occurrences. Regulatory document REGDOC-3.1.3 incorporates and clarifies requirements found in the Nuclear Safety and Control Act (NSCA) and regulations made under the NSCA, including requirements for content and timing of reports. Additionally, it provides guidance on the interpretation and scope of application of these requirements in the context of Class II nuclear facilities, nuclear substances and radiation devicesand waste nuclear substance licensees. Further to the reporting requirements set by the NSCA and the regulations, a licence may contain any term or condition that identifies a reporting requirement and the time frame for submitting the report. This document provides guidance on these licence conditions, including the submission of an annual compliance report (ACR).

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.
