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.

Neutron scattering cross sections have been measured for 233U and 232Th, using rolled metal samples, in a moderated spectrum from a 5-mg 252Cf source. The scattered neutrons were detected by two 3He detectors in an annular geometry. The experimental data were corrected for thermal and epithermal fissions, epi-thermal scattering, air scattering, room background, and self-absorption. The self-absorption corrections for the four 233U targets, covering a wide range in thickness, were obtained from Monte Carlo calculations. Absorption corrections for the two 233Th targets were avoided by using standards having the same absorption thicknesses. The results obtained were 12.30 ± 0.70 b for 233U and 12.78 ± 0.30 b for 232Th relative to vanadium with an assumed scattering cross section of 5.02 ± 0.10 b. The corresponding values for the ENDF/B-III file are 14.06 and 11.92 b, respectively.
