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 results of a program are reported whose objective has been to establish the reliability and accuracy of tissue kerma estimates near the ground, out to deep penetration ranges, from a point neutron source in an air-over-ground geometry. The results take the form of expected error in calculated neutron and secondary gamma-ray kerma out to 2-km range for any neutron source height and energy spectrum. In the first of two approaches, experimental data permitting absolute evaluation in one dimension is used in conjunction with an evaluated calculational procedure for two dimensions to obtain overall error estimates. In the second approach, errors obtained from comparisons of measurement and calculation in air-over-ground geometry are evaluated to obtain overall error estimates. When the results of these two approaches are averaged, it can be concluded with confidence that kerma to 2 km will probably be calculated to be 10 to 15% lower than measured values for neutrons and 20 to 25% lower for gamma rays when this cross-section set and recommended calculational procedure or equivalents are used.
