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.

Some results of a detailed study of neutron diffusion in water containing 1/v and non-1/v absorbers are reported. We have solved the Boltzmann transport equation in the diffusion approximation using the multigroup method and the recent neutron scattering kernel proposed by the authors. The calculated values of diffusion length, L(T), in pure water in the temperature range from 0.5 to 60°C are found to be in good agreement with most of the experimental results. (Results based on the Nelkin kernel are consistently higher.) The variation of L(T) is nonlinear up to 10°C, but in the temperature range from it can be expressed as L(T) = L (10°C) + 0.00446 (T − 10). The computed values of the diffusion length in water poisoned with various concentrations of boron are consistent with the experimental results of Martinho and Costa Paiva. For non-1/v absorbers—cadmium and gadolinium solutions—calculations on space-dependent neutron spectra are reported. The calculated values of for various concentrations of cadmium and gadolinium are in good agreement with the experimental data of Goddard and Johnson. For high concentrations of cadmium, notable differences are observed between the present calculations and those based on the Nelkin kernel.
