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 probability table method (PTM), used in unresolved resonance region calculations, assumes that cross sections are not energy correlated. Strong cross-section energy auto-correlations are noted for some heavy nuclides that could affect the use of the PTM in the unresolved resonance region or its extension to the resolved resonance region. Uranium-238 has strong cross-section auto-correlations and is considered a severe test material for the PTM. Monte Carlo calculations of capture rates in 238U at 500, 1000, and 2000 eV do not show differences between the PTM and exact methods within an ∼1% calculational uncertainty. These results show that strong auto-correlations do not interfere with the use of the PTM in the resolved and unresolved resonance regions.
