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.

A correlation technique has been developed to make the accuracy of complex and long-running resonance treatments available in fast, routine calculations. The technique is based on the subgroup method and is used to generate group-averaged resonance reaction rates. By fitting the correlation to several detailed auxiliary resonance calculations, a set of weights (the Lebesgue measure) is obtained. The weights can then be applied to a wider range of new cases. Use of the correlation technique results in one-tenth the computational burden of the detailed resonance treatment, yet the results duplicate the detailed calculations to within 0.01% in keff.
