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 fast neutron emission spectrum of 252Cf has been investigated by means of proton-recoil spectrometers. With a large (900-mm-long) counter tube, the neutron distribution between 0.9 and 10 MeV could be determined. Monte Carlo calculated response functions were applied to unfold the measured proton-recoil distributions. With a smaller (466-mm-long) counter tube, the energy interval between 1 and 3 MeV was examined in a search for neutron fine-structure groups. No such groups could be established.
