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.

The double-differential cross sections of outgoing neutrons and alpha particles of the 12C(n,xn) and 12C(n,x) reactions are measured. A new nuclear reaction model for light nuclei is proposed to analyze the measured data. Because of a strong recoil effect in light nucleus reactions, the energy balance is strictly taken into account. Based on this new method, the LUNF code is developed to calculate all kinds of reaction cross sections and energy-angular distributions for the n + 12C reaction in the 4.8- to 20-MeV energy region. The reaction channel of (n,n'3) may proceed via a number of different reaction channels, as sequential particle emissions and two-body separation. The comparisons of the calculated results with the measured experimental data indicate that the model calculations are successful for outgoing neutrons. Also, kerma factors derived from the calculated results are compared with the measurements.
