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.

Energy and angular distributions of alpha particles from the bombardment of carbon foils with 14.1-MeV neutrons were measured with a magnetic spectrometer. The observations included alpha particles with energies above 1 MeV emitted at angles between 19 and 135 deg. The cross section for alpha-particle emission obtained by integrating over emission angle was 402 ± 46 mb. From these data and from evaluations of the elastic and inelastic scattering cross sections, a kerma factor (energy deposition) of 1.84 ± 0.16 × 10−9 cGy·cm2 was deduced. The present cross section for the 12C(n,n′3α) reaction is much lower than previous measurements.
