Description

REGDOC-2.12.2, Nuclear Security for High-Security Sites, was created to provide guidance for Canadians on how to meet the requirements of the new Nuclear Security Regulations and other federal legislation and regulations as necessary.

REGDOC-2.12.2 is based on International Atomic Energy Agency standards and guidance, operational experience, and the Government of Canada’s and like-minded international entities’ best practices for establishing and maintaining a nuclear security program.

REGDOC-2.12.2 is a new regulatory document. The 2.12 series of regulatory documents was created when the Nuclear Security Regulations were repealed and replaced on October 30, 2025. This series includes REGDOC-2.12.1, REGDOC-2.12.2 and REGDOC-2.12.3, which replace previous regulatory documents under the old Nuclear Security Regulations and that had the same number. Important note: The new REGDOC-2.12.1, REGDOC-2.12.2 and REGDOC-2.12.3 cover different topics than the documents they are replacing
