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.

This paper presents a review of fire protection operating experiences from selected magnetic fusion experiments and other facilities to support design decisions, safety analysis, and risk assessment work for future fusion experiments. Quantitative estimates of fire protection system failure rates and fire accident initiating event frequencies are presented. Safety concerns of spurious actuation and water leakage are discussed for fire suppression systems. This information should be useful to fusion system designers and safety analysts, such as the team working on the design of the International Thermonuclear Experimental Reactor (ITER).
