Argentina's state-owned uranium dioxide producer, Dioxitek, achieved a record production of 190 tonnes in 2025, enabling the country to meet the uranium needs of its nuclear power plants without imports. Dioxitek, a subsidiary of the National Atomic Energy Commission (CNEA), was established to ensure a sustainable supply of uranium dioxide and strategic radioisotopes, such as cobalt-60.
The company processes uranium concentrate, uranium dioxide scrap, and ammonium diuranate into nuclear-grade UO2 powder, which is used for fuel pellets in three nuclear plants: Atucha I, Atucha II, and Embalse. The production increase is attributed to a comprehensive restructuring and process improvements at the Córdoba plant, highlighting the commitment of Dioxitek's personnel. The Atucha plants and Embalse together contribute about 5% of Argentina's electricity.
