DOE extends Centrus’s HALEU production contract by one year
Centrus Energy has announced that it has secured a contract extension from the Department of Energy to continue—for one year—its ongoing high-assay low-enriched uranium (HALEU) production at the American Centrifuge Plant in Piketon, Ohio, at an annual rate of 900 kilograms of HALEU UF6. According to Centrus, the extension is valued at about $110 million through June 30, 2026.

PURNIMA, a PuO2-fueled copper-reflected zero-energy fast reactor at Trombay, was built as a mockup of the proposed air-cooled 30-kW Kalpakkam Pulsed Fast Reactor. This paper describes the salient features of PURNIMA and discusses the calculational methods used and the control philosophy and operational procedures adopted. Important aspects relating to the overall safety are examined in detail. Some of the experiments carried out with this facility are also briefly reported.
