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.

Tritium processing operations have been performed at the Savannah River Site since 1955. It was determined in the early 1980's that new tritium facilities were required in order to meet increasingly stringent safety and environmental requirements while maintaining productivity. Construction of a new tritium handling facility, the Replacement Tritium Facility (RTF), began in 1987. The RTF incorporates the latest technology and design philosophy to mitigate accident consequences, enhance operational safety, minimize tritium losses to the environment, and ensure material safeguards and security. The RTF is currently completing startup testing.
Tritium handling and processing operations are common to both national defense and fusion technology programs. Disseminating the lessons learned during the startup of a new tritium handling facility is important to the success of future tritium handling missions.
