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.

The near-equilibrium energy spectrum of the delayed neutrons from the fast neutron-induced fission of 240Pu has been measured over the energy range from 40 to 1500 keV. The spectrum is somewhat similar in shape to near-equilibrium spectra previously reported for other isotopes, and the peak structure is consistent with results from both fissionable isotopes and from various individual delayed neutron precursors.
