ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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 activation cross sections for the 99Tc(n,p)99Mo, 99Tc(n,α)96Nb, 99Tc(n,n′α)95Nb, and“Tc(n,n′)99mTc reactions at 13.5 and 14.8 MeV have been measured by using the deuterium-tritium neutron generator (the Fusion Neutronics Source) at the Japan Atomic Energy Research Institute. The results were compared with experimental values from the literature, evaluated activation cross-section files, and predictions by current cross-section computer codes. Special emphasis was placed on the feasibility of producing high-specific-activity“Mo, to be used in medical applications, via the 99Tc(n,p)99Mo reaction in the Fusion Material Irradiation Facility. A factor of 3 overestimate of 99Mo production resulted when the REAC *2 code was used. It is suggested that this discrepancy is due primarily to the factor of 5 difference in cross sections at the 14-MeV region between the REAC*2 data and the current measurement.
