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.

Diffusion coefficients of sodium vapors in argon and helium gases were measured from 380 to 560°C by the Stefan method under atmospheric pressure. Careful considerations were made in the design of the apparatus to obtain data within a ±10% error, which arises from several sources inherent in the Stefan method. The experimental errors inherent in such sources were theoretically evaluated. The experimental diffusion coefficients were compared with those predicted by the majority of previous theoretical expressions. The comparisons revealed that the expressions proposed by Moulaert for the sodium-argon mixture and by Aref'yev et al. for the sodium-helium mixture predicted values that were in excellent agreement with the measurements.
