CNSC renews Cameco’s uranium mine licences for Key Lake, McArthur River and Rabbit Lake Operations


October 29, 2013

Following a public hearing, the Canadian Nuclear Safety Commission (CNSC) announced today its decision to renew its uranium mine and mill operating licences for Cameco’s Key Lake, McArthur River and Rabbit Lake operations located in northern Saskatchewan. The 10-year licences will be valid from November 1, 2013 until October 31, 2023. 

In making its decision, the Commission considered information presented at a public hearing held in La Ronge, Saskatchewan from October 1 to 3, 2013. During the public hearing, the Commission received and considered submissions from Cameco and 27 intervenors as well as CNSC staff recommendations.

During the term of the renewed licences, CNSC staff will provide annual reports on the operation of the three facilities at public proceedings of the Commission. Some of those proceedings will be held in northern Saskatchewan with public participation and a special focus on the environmental performance of these facilities, with emphasis on releases to air, water and soil.

The Record of Proceedings and Decisions on Key Lake, McArthur River and Rabbit Lake installations and transcripts of the hearing are available on the CNSC Web site at, or by contacting the CNSC. The webcast of the hearing is also archived on the same site for a period of 90 days.

The CNSC regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; and to implement Canada's international commitments on the peaceful use of nuclear energy.
