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.

Comparative measurements of neutron flux for low-level irradiations in the MOL-∑∑ reactor have been carried out using gold and indium foils and various solid-state nuclear track detectors (SSNTDs) in conjunction with fissile (n,f) and fertile (6Li and 10B) (n,α) converter foils as well as intrinsic detectors. Experimental and computed values of thermal and epithemal neutrons, using 6Li and 10B, are also presented for other arrangements. The results show good agreement and internal consistency for both thermal- and fast-neutron fluences, thus confirming the use of SSNTDs as absolute dosimetric devices.
