Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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 neutron total cross section of 10B has been determined between 90 and 420 keV neutron energy by means of a transmission measurement on a boron sample enriched in 10B. Deviations in shape from other measurements are within the statistical accuracy of the present measurement and are smaller than 1.5%. In the measured energy region, no indication of narrow resonance structure was found, and the deviation of the total cross section from an E−1/2 energy dependence above 100 keV was confirmed. An analysis using the R-matrix formalism showed that this deviation can be associated with the 7/2+ s-wave resonance at 370 keV.
