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 possibility of constructing an intense hard-spectrum neutrino source based on the β‾ decay of 8Li (T1/2 = 0.8 s) is studied. Applications of such a source are considered in neutrino investigations. The source can be developed on the basis of a neutron-to-antineutrino lithium converter through (n, γ) activation of 7Li isotopes irradiated by neutrons from the active zone of a reactor. The physical parameters of the lithium converter are compared with those of other neutrino sources. Different geometries for a converter using heavy water are considered. The converter efficiency is calculated as a function of the purity of the 7Li isotope and the expected tritium activity values. The cross section of the neutrino-deuteron reaction increases rapidly in both the neutral ( + d → n + p + ) and the charged ( + d→ n + n + e+) channels as the converter efficiency is improved. The real efficiency is 9%, and the cross sections are enhanced by factors of 2.5 and 5 in the respective channels.
