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.

Developing the necessary structure and capabilities of a regulatory body for a comprehensive, independent safety assessment of NPP designs needs substantial time and resources. In many cases, neither sufficient time nor sufficient resources will be available for countries embarking in nuclear power now with the aim to supply carbon free energy in the near future. The panel members will present and discuss various options for the use of Third-Party oversight of design, construction and operation with a particular focus on how the deployment of nuclear power reactors can be enabled for newcomer countries. Examples of options to be discussed are: the model already established by Lloyd's Register in the shipping industry as pseudo-regulators for design, construction, and operation, with some experience in the assurance of nuclear-powered submarines; a concept for an Independent Technical Support Organization funded by major national regulatory bodies; a concept for a Third-Party review funded by the reactor vendor; a concept for the informed adoption of safety assessments or design approvals by well-established regulatory bodies. The role international organizations could play in these approaches will also be addressed.
