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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 gamma-ray energy spectra resulting from neutron capture in 238 were calculated using the gamma-ray cascade code DUCAL for incident neutrons in the energy range 0.0 ≤ E ≤ 1.1 MeV. The overall spectral shapes generated for thermal and epithermal neutron capture agree quite favorably with an integral measurement. Absolute comparisons of the generated spectra with differential capture yield measurements exhibit general agreement. Variations in the spectral shape with neutron energy are noticeable above 3.0 MeV.
