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 transport of heavy charged particles produced by the 10B (n,α) nuclear reaction is predicted using a mean-range straight-flight model. The slowing down of these particles in a gas adjacent to the coating where they are born is described in terms of their flux energy spectrum, scalar flux, average energy, and energy-loss rate. These results are used in a plasma kinetics model which is compared to measurements of metastable excited state densities in helium and neon plasmas created by the heavy charged particles. The space-dependent fast primary electron (δ ray) energy spectrum produced by the heavy charged particles in helium is calculated, as well as the total number of fast primary electrons and their average kinetic energy.
