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.

Plane-strain linear elastic models with constant shrinkage coefficients were analyzed to determine the relationship of cross-sectional shapes to irradiationinduced stresses in graphite moderator components. If a relaxation factor is known, results of this study can be applied to a system in viscoelastic creep. The geometries considered are cylinders and prisms containing one or more cylindrical holes and sectors of these configurations. Although particular mechanical properties and fast-flux distributions are assumed, the results imply predictions for other conditions. In the study of multihole prisms, little difference in maximum stresses exists; however, some simply connected sectors have almost negligible in-plane stresses. Concentric cylinders and cylindrical sectors exhibit a very significant reduction of stresses when compared with those of the related thick-walled cylinder.
