The Uranium segment focuses on the exploration, mining, milling, and sale of uranium concentrates, anchored by major assets like the McArthur River and Cigar Lake mines in Saskatchewan, as well as operations in the United States and Kazakhstan. The Fuel Services segment provides refining, conversion, and fabrication of uranium concentrate into fuel for nuclear reactors. Through its 49% ownership interest in Westinghouse Electric Company, Cameco also participates in nuclear reactor technology manufacturing, engineering support, and plant maintenance services. The company primarily serves commercial nuclear utilities and government agencies across the Americas, Europe, and Asia.
