CNSC amends Ontario Power Generation’s power reactor operating licence for its Darlington Nuclear Generating Station to authorize the production of Molybdenum-99

The Canadian Nuclear Safety Commission (CNSC) announced today that it has amended the power reactor operating licence held by Ontario Power Generation Inc. (OPG) for its Darlington Nuclear Generating Station (NGS) in the Municipality of Clarington, Ontario. This decision follows a public hearing in writing. The amended licence authorizes OPG to produce Molybdenum-99 (Mo-99) at the Darlington NGS.

In making its decision, the Commission considered written submissions from OPG, CNSC staff, and 10 intervenors. The CNSC also made participant funding available through its Participant Funding Program, and invited interventions from Indigenous groups, members of the public and stakeholders in this matter. Five requesters received participant funding to assist with their interventions.

After reviewing all submissions, the Commission concluded that OPG is qualified to carry out the Mo-99 production activities that the amended licence will authorize. It also concluded that OPG will make adequate provision for the protection of the environment, and the health and safety of persons.

The record of decision is available on request to the Commission Secretariat at interventions@cnsc-ccsn.gc.ca. The decision will also be posted in both official languages at nuclearsafety.gc.ca at a later date. All submissions are available on the CNSC website.

The CNSC regulates the use of nuclear energy and materials to protect health, safety, security and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
