On January 9, 2024, the Canadian Nuclear Safety Commission (CNSC) announced the Commission’s decision amend the licence for Chalk River Laboratories, authorizing Canadian Nuclear Laboratories (CNL) to construct a near surface disposal facility (NSDF) on the site. The Commission made the decision under the Nuclear Safety and Control Act following their conclusion that CNL’s NSDF Project is not likely to cause significant adverse effects, given that CNL implements all proposed mitigation and follow-up monitoring, which include ongoing engagement with Indigenous Nations and communities. As well, the Commission assessed that the safety case for the facility as robust and indicative that the NSDF will meet its required design life of more than 500 years. Currently, CNL is taking time to review and analyze the Record of Decision before determining our next steps. CNL is aware that applications have been filed for a judicial review of the CNSC’s decision to approve construction of the NSDF.
