Consultation on DIS-21-02, Proposals to Amend the Nuclear Security Regulations, is now closed. Thank you to everyone who submitted comments.

The CNSC is proposing amendments to the Nuclear Security Regulations (NSR). The proposed changes to the NSR take a performance objectives-based approach to regulating nuclear security by affording licensees greater flexibility in the measures and approaches they can use to meet nuclear security regulatory requirements. Accordingly, the CNSC is also taking this opportunity to revise and align its nuclear security regulatory documents (REGDOC-2.12 series) to clarify guidance on how nuclear security regulatory requirements can be met.

The purpose of this discussion paper is to gather feedback from licensees, proponents, the Canadian public, Indigenous peoples, and other stakeholders on the proposed amendments. All feedback received during this consultation will inform the CNSC’s approach. Stakeholders will have additional opportunities to comment during the Canada Gazette, Part I, pre-publication process and when the regulatory documents are posted for public consultation.


The consultation period for DIS-21-02 has ended.
