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.

Total neutron cross section measurements have been made on metallic samples of Ti, Zr, and Hf with the MTR crystal spectrometer. The Ti cross section was measured in the energy region 0.025 to 45 ev and values of 4.19 ± 0.04 b and 6.09 ± 0.13 b were obtained for the bound atom scattering and 2200 meters/sec absorption cross sections. The Zr cross section was measured in the energy region 0.02 to 78 ev and a value of 6.40 ± 0.07 b was obtained for the bound atom scattering cross section. The Hf cross section was measured from 0.04 to 3.5 ev and a value of 102 ± 3 b for the 2200 m/sec absorption cross section is reported. Energy values of 1.095 ± 0.005 ev and 2.378 ± 0.016 ev were determined for the peak cross sections of the first two Hf resonances. Values of σ0 = 6030 ± 80 b, Γ = 0.068 ± 0.001 ev and gΓn = 0.163 ± 0.003 mv were obtained for the 1.095 ev resonance.
