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.

Target rods irradiated in the High Flux Isotope Reactor will be chemically processed for the recovery and decontamination of the various actinide elements produced in the reactor. The processing equipment will be located in four of the nine cubicles and seven tank pits of the Transuranium Processing Plant cell bank. Activity and contamination levels in the process equipment necessitate the use of remote or semiremote maintenance techniques. Maintenance and plant modifications are simplified by a remotely operated piping disconnect developed for this purpose. The choice of materials of construction for the process equipment and piping is limited by the hydrochloric acid environment and intense radioactivity of the process solutions. Hastelloy C appears to be acceptable for low temperature waste service, while only tantalum, Zircaloy-2, or glass is suitable for process equipment.
