Operating Performance of the McArthur River Mine
The CNSC produces an annual report on the performance of uranium fuel cycle and processing facilities, which includes the McArthur River Mine. The report provides information on events, facility modifications, and areas of increased regulatory focus. It also tracks data on:
- public and worker radiation dose
- lost-time incidents for workers
- environmental monitoring results
- environmental reportable spills and corrective actions taken
- current financial guarantees for future decommissioning costs
Read the report to learn about operating performance of the McArthur River Mine.
As part of CNSC's regulatory requirements, major licensees must have robust public information and disclosure programs in place. These programs, for major uranium mines and mills, include a disclosure protocol developed in consultation with community stakeholders.
