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.

Water breeder reactors based on thermal water reactors have the advantages of a well-proven technology, a wide operational experience, and an acceptable safety status, the latter from using water as a coolant and having a negative void coefficient. Water breeder reactors are now in operation for the 232Th-233U cycle and are being designed for the 238U-Pu cycle. This paper proposes a water breeder system in which two reactors operate in symbiosis, one using 238U-233U as fuel and producing plutonium, and the other using 232Th-Pu as fuel and producing 233U. Thus, each reactor feeds the other. From the breeding point of view, the combined system has an advantage over the separate 238U-Pu and 233Th-233U cycles.
