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.

ANS standard updated for determining meteorological information at nuclear facilities
Following approval in October from the American National Standards Institute, ANSI/ANS-3.11-2024, Determining Meteorological Information at Nuclear Facilities, was published in late November. This standard provides criteria for gathering, assembling, processing, storing, and disseminating meteorological information at commercial nuclear power plants, U.S. Department of Energy/National Nuclear Security Administration nuclear facilities, and other national or international nuclear facilities.

In this study, activation cross sections were measured for the 71Ga(n,)72m+gGa reaction at three different neutron energies from 13.5 to 14.8 MeV. The fast neutrons were produced via the 3H(d,n)4He reaction on the Pd-300 Neutron Generator. Natural high-purity Ga2O3 powder was used as target material. Induced gamma activities were measured by a high-resolution gamma-ray spectrometer with a high-purity germanium detector. The data for the 71Ga(n,)72m+gGa reaction cross sections are reported to be 1.93 ± 0.12, 1.50 ± 0.09, and 0.91 ± 0.05 mb at 13.5 ± 0.2, 14.1 ± 0.2, and 14.8 ± 0.2 MeV incident neutron energies, respectively. Results are discussed and compared with some corresponding values found in the literature.
