Cameco is a prominent supplier of uranium processing services required to produce fuel for the generation of clean electricity. We operate the world's largest commercial refinery in Blind River, have about 21% of the world UF6 primary conversion capacity in Port Hope, and are a leading manufacturer of fuel assemblies and reactor components for CANDU reactors at our facilities in Port Hope and Cobourg.

Our focus is on cost-competitiveness and operational efficiency. Our fuel services segment is strategically important because it helps support the growth of the uranium segment. Offering a range of products and services to customers helps us broaden our business relationships and expand our uranium market share.

    2023 Q3 Update


    Fuel services produced 2.0 million kgU in the third quarter of 2023, 33% higher than the third quarter last year, and 9.6 million kgU in the first nine months, which was 3% higher than the same period last year.

    In our fuel services segment, which includes the production of UO2, UF6 and heavy water reactor fuel bundles, we expect to produce between 13 million and 14 million kgU of combined fuel services products in 2023 (outlook and production results are not disclosed by individual product line).

    In addition, at our Port Hope UF6 conversion facility we are working on increasing annual production to 12,000 tonnes in 2024 to satisfy our book of long-term commitments and demand for conversion services.
