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 intensities of the weak 2158- and 2505-keV gamma rays following the β‾ decay of 60Co were measured by applying the photonuclear reactions 9Be(γ,n) and 2D(γ,n). The results obtained were I(2158) = (2.0 ±1.3) ×10-5 I(2505) = (0.9 ± 0.7) × 10-7 photons per decay of 60Co. The present result for I(2158) agrees with other data found in the literature within stated errors, whereas that for I(2505) is significantly smaller than previous estimates. From the present value of I(2158), the rate B2 and logarithmic comparative half-life log f2t2 of the second-forbidden unique β‾ decay, which is intimately related to this intensity, was estimated as B2 ≤ (15.0 ± 9.8) × 10-3% and log f2t2 ≥ , respectively.
