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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Implementation of changes in the U.S. nuclear fuel cycle for emerging needs such as high-assay low-enriched uranium, advanced fuel types, advanced medical isotopes, and plutonium processing will require new facilities and their associated processes and equipment. Integration of nuclear criticality safety (NCS) principles, limits, and controls should be incorporated early in the design process. This session will include papers which address the new strategies which may be employed to integrate NCS into the design process, operating experience and lessons learned from past design projects, and the associated risks and challenges faced by NCS practitioners during the design processes
