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.

Modular Heliotron concepts with well-defined and efficient closed helical divertor are studied. The physics optimization of this system has been carried out based on the LHD (Large Helical Device) concept by means of vacuum magnetic surface analyses and finite-beta calculations. The effectiveness of this new modular coil system and its magnetic configuration are clarified. Engineering design of this Modular Heliotron Reactor (MHR) is also carried out based on this physics concept and engineering scalings, and the required machine parameters for DT ignition reactors are clarified.
