Nuclear facility – McArthur River Operation

Cameco owns and is licensed to operate the McArthur River Operation, located in northern Saskatchewan. The CNSC has full-time staff in Saskatoon and Ottawa who periodically perform inspections to evaluate operations and to verify compliance with regulatory requirements and licence conditions.

A rectangular green building is in the middle of a paved lot surrounded by grass and trees. There is a tall, slim portion of the building that extends into the sky. Attached to its side is a metal ladder-like structure that angles out to the ground. Surrounding the building are various metal structures and crates.
