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.

Neutron transmissions through 0.076-, 0.254-, 1.080-, and 3.620-cm-thick samples of isotopically enriched 238U have been measured from 0.88 to 100.0 keV using a time-of-flight technique over a path length of 150 m, the ORELA pulsed neutron source, and a 13-mm-thick lithium-glass detector. To obtain resonance parameters, these transmissions from 0.88 to 4.00 keV have been simultaneously least-squares shape-fitted with a multilevel Breit-Wigner cross-section formalism. In general, large neutron widths are obtained, resulting in an s-wave strength function of (1.208 ± 0.045) × 10−4 over the interval from 0.0 to 4.0 keV. An absolute energy scale accurate to 2 parts in 10 000 was established.
