Today, the Canadian Nuclear Safety Commission (CNSC) announced the Commission's decision to amend Ontario Power Generation's (OPG's) power reactor operating licence for the Darlington Nuclear Generating Station (NGS) to authorize the production of the cobalt-60 (Co-60) radioisotope. This decision follows a public hearing in writing with interventions, and the amended licence will remain valid until November 30, 2025.
The Darlington NGS is located in the Municipality of Clarington, Ontario, and on the traditional lands and waters of the Michi Saagiig Anishinaabeg. These lands are covered by the Gunshot Treaty (1877-88), the Williams Treaties (1923), and the Williams Treaties Settlement Agreement (2018).
In making its decision, the Commission considered written submissions from OPG, CNSC staff and 12 intervenors. After reviewing all submissions, the Commission concluded that OPG is qualified to carry on the activities that the amended licence will authorize.
