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.

The main results of several years of research on neutron and gamma-ray physics in the Purdue Fast Breeder Blanket Facility (FBBF) are summarized. Presented are neutron capture rates in 238U, 232Th, gold, tungsten, and manganese, and fission rates in 235U and 239Pu. Neutron spectra are determined from proton recoil energies over the range from 2 keV to 2 MeV. The energy deposition of the gamma-ray field is measured with thermoluminescent detectors. Since the FBBF is a source-driven facility, all results are obtained on an absolute basis and are compared with corresponding calculations. Most of the results are presented as calculated/experimental trajectories except for the neutron spectra. The absolute and complete experimental results will be presented in separate papers. The comprehensive and coherent interpretation of deviations between calculated and experimental results is explored. Three major deviations are identified; they concern the “bulk” of the neutron population, the low-energy wing of the spectrum, and the space dependency of resonance absorption.
