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 validity of the approximations of neglecting proton attenuation due to nuclear collisions and all reaction products from nuclear collisions in space vehicle shielding studies is tested. Comparisons of absorbed-dose and dose-equivalent results obtained with the production and transport of nuclear-reaction products included with similar results obtained using the approximations are presented. The use of the approximations is found to lead to an overestimation ( a factor of two) of the absorbed dose and dose equivalent for a wide range of incident Van Allen belt and solar-flare proton spectra and for a variety of shield thicknesses and shield materials.
