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 densities of liquid lead and of liquid nickel-lead solutions containing up to about 3.5 atomic per cent nickel were measured as a function of temperature using a modified Archimedean method. It was found that the densities of the nickel-lead solutions were greater than that of pure liquid lead and increased with increase in nickel content. Partial molal volumes for nickel and lead were then determined by the method of intercepts. The results indicate that for the composition region investigated the partial molal volume of lead does not differ significantly from the molal volume of lead and the partial molal volume of nickel approaches a value of zero at high dilution.
