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 neutron capture width of the 27.7-keV s-wave resonance in 56Fe has been determined using a setup completely different from most of the previous experiments. A pulsed 3-MV Van de Graaff accelerator and the 7Li(p,n) reaction served as a neutron source. Capture gamma rays were observed by a Moxon-Rae detector and gold was used as a standard. The samples were positioned at a flight path of only 7.6 to 8.0 cm. This allowed the use of very thin samples avoiding large multiple scattering corrections. Three metallic disks enriched in 56Fe were used with a thickness between 0.6 and 0.15 mm. Events due to capture of resonance scattered neutrons in the detector or surrounding material were completely eliminated by time-of-flight. The result for the capture width is Γγ = 1.01 eV with a statistical uncertainty of 1.3% and a systematic uncertainty of ∼5%.
