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.

An activation method is proposed for in-core neutron flux distribution measurement. A neutron flux distribution being considered is transformed into integral activities by using an activation fluid circulating through a core. Then a set of measured integral activities is transformed inversely to a neutron flux distribution which is approximated by a series of shape functions, such as the Fourier series. Numerical simulation of the results reveal that typical axial neutron flux distributions in a boiling water reactor can be measured within an accuracy of ±15%.
