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.

The volatility of a proposed fusion reactor structural alloy, Path-A Prime Candidate Alloy, a modified 316 stainless steel, was investigated. Tests were conducted in nonstatic air at temperatures from 723 to 1473 K (450 to 1200°C) for durations of 1 to 100 h. Results indicate that no significant volatility occurred for any major alloying constituent with the notable exception of molybdenum. The volatility of molybdenum is temperature dependent. An apparent activation energy was determined for the volatility of molybdenum from 1073 to 1473 K.
