Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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 nuclear energy concept based on the integrated operation of a beam-driven hybrid fusion reactor and a companion fission reactor is investigated. The fuel for the fusion component is taken to be only deuterium, while the fissile fuel consists of the plentiful fertile nuclei 232Th or 238U. The different system features associated with various deuterium cycles are examined, and parametric reactor physics constraint relationships are established. It is concluded that the synergetic fusion-fission energy system described here displays very favorable energetic characteristics and, in addition, possesses the feature of total self-sufficiency with respect to fissile fuel supply.
