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.
Technical Session|Panel|Sponsored by FCWMD
Monday, November 13, 2023|1:00–2:45PM EST|Fairchild East/West
Session Chair:

Alternate Chairs:

Jean-Francois Lucchini
Session Organizer:
The FCWMD has approximately 12 standards maintained by the FWDCC. Many of these standards are endorsed by the NRC and written to support the existing LWR fleet of reactors (e.g., ANS‐57.1‐1992 Design Requirements for LWR Fuel Handling Systems). However, with the significant effort under way to develop and deploy advanced reactor (AR) concepts, many of these standards may either not apply to these AR concepts or require exemptions to be utilized to allow for their application. This panel will discuss the FWDCC maintained standards and identify potential issues and needs to update them to allow for their application to ARs.
