Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

Anisotropy in the scattering of thermal neutrons from beryllium oxide has been investigated. Elastic differential scattering cross sections have been calculated by replacing the δ function occurring in the expression by a Gaussian. The effect of changing the width of the Gaussian on the differential cross section has also been studied. Anisotropy in inelastic scattering has been calculated for coherent one-phonon and incoherent one- and two-phonon processes. Using these differential cross sections, we have calculated the energy distribution of neutrons scattered along different directions by a beryllium oxide slab and these results are compared with corresponding measured results. The agreement between the two sets of results is found to be good.
