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.

Uranium carbide containing about 5.2 w/o carbon has been irradiated to nominal burnups of 1000 and 5000 Mwd/ton of carbide. The results are generally encouraging, although some cracking has been observed. The observed density decreases were about the same at 1000 and 5000 Mwd/ton irradiations, being 0.7 to 2.5 and 0.6 to 2.5% respectively. The problems and questions raised by these irradiations are discussed. Additional irradiations are planned to study the effects of composition and of burnups to 15,000 Mwd/ton of carbide.
