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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 neutron total cross section and the shape of the neutron capture cross section of 232Th have been measured in the energy range from 0.006 to 18 eV at the Rensselaer Polytechnic Institute Gaerttner Linac Laboratory. The neutron total cross section was obtained from transmission measurements using metallic 232Th samples and a 6Li glass neutron detector. The total cross section above 0.1 eV is in good agreement with the ENDF/B-V evaluation. Below 0.1 eV, where Bragg scattering is important, the measured total cross section is significantly lower than the evaluated total cross section. The shape of the neutron capture cross section was obtained from 0.009 to 18 eV using a ThO2 sample and a 1.25-m-diam liquid scintillator detector. The shape of the measured capture cross section above 0.1 eV is in good agreement with a recent shape measurement at Brookhaven National Laboratory. The neutron capture cross section below 0.1 eV is found to increase less rapidly than 1/v with decreasing neutron energy.
