ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Neutron total cross sections of elemental bismuth were measured with broad resolutions from 1.2 to 4.5 MeV to accuracies of ∼1%. Neutron differential elastic scattering cross sections were measured from 1.5 to 4.0 MeV at incident neutron energy intervals of ≲0.2 MeV over the scattered neutron angular range ∼20 to 160 deg. Differential neutron cross sections for the excitation of observed states in bismuth at 895 ± 12, 1606 ± 14, 2590 ± 15, 2762 ± 29, 3022 ± 21, and 3144 ± 15 keV were determined at incident neutron energies up to 4.0 Me V. The measured values were interpreted in terms of an optical-statistical model.
