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.

EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

The traditional role of nuclear power has been the production of base-load electricity. However, the needs of the electricity grid are changing because of (a) the introduction of significant electricity generation by nondispatchable wind and solar and (b) increasing restrictions on using fossil fuels because of concerns about climate change. To meet these changing requirements, a fluoride-salt–cooled high-temperature reactor (FHR) with a nuclear air-Brayton combined-cycle power system is proposed. This technology (a) can be the enabling technology for a low-carbon nuclear-renewables electrical grid and (b) can substantially improve nuclear power plant economics by increasing plant revenue by 50% or more relative to a base-load nuclear power plant. This is because the plant can be operated at full power to produce base-load electricity, stabilize the grid, produce process heat to reduce sales of low-priced electricity, and produce peak electricity with auxiliary natural gas or hydrogen. The market basis for this reactor is described with implications on the design requirements for an FHR.
