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.

A track-etch method of neutron radiography using a new 10B4C converter was studied. Various characteristics of the track-etch films were measured and compared with a conventional emulsion method. The etch pit production rates, resolution powers, and graininess relating to the etching conditions were precisely investigated. Various fine radiographs were obtained, including simulated fast breeder reactor fuel and irradiated fuel pins. The resolution power and the image quality of the track-etch radiography were comparable to those using a combination of gadolinium foil and fine grain films with shorter exposure times.
