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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Measurements of differential cross sections for fast neutrons scattered by carbon are presented for 14 incident neutron energies between 8.0 and 14.5 MeV. The measurements were performed with the four-detector neutron time-of-flight facility of the Centre d'Etudes de Bruyères-le-Châtel tandem Van de Graaff accelerator. The angular distributions for elastic and inelastic scattering to the first excited level of 12C were obtained over the angular range from 10 to 160 deg. The experimental uncertainties vary from 7 to 15% for the differential elastic scattering cross sections and from 8 to 22% for the differential inelastic scattering cross sections. These measurements partially fill in an energy range that was previously characterized by a lack of data. The angle-integrated cross sections are compared to the evaluated values of ENDF/B, and significant discrepancies are shown. The present data were included in an evaluation work on carbon carried out in this laboratory. The consistency of total cross-section measurements with our data and other partial cross sections is discussed.
