Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

A set of high-temperature thermodynamic properties for sodium in the two-phase and subcooled-liquid regions has been predicted for the region between the low-temperature properties recommended by Golden and Tokar and the critical temperature. This set of high-temperature properties is recommended for consistent thermodynamic calculations in reactor safety analyses involving sodium. The saturation properties determined are: vapor pressure, liquid and vapor density, liquid and vapor enthalpy, liquid and vapor entropy, liquid compressibility (adiabatic and isothermal), liquid thermal-expansion coefficient, and liquid specific heat (constant pressure and constant volume). The subcooled-liquid properties determined are: pressure, enthalpy, entropy, compressibility (adiabatic and isothermal), thermal-expansion coefficient, and specific heat (constant pressure and constant volume).
