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.

Statistical analysis of test results obtained by crushing SiC and ZrO2 yielded the optimum design characteristics for a miniature jaw crusher. The device was needed to reduce subcritical amounts of plutonium ceramics to sizes suitable for reactor use. Tests were conducted with a prototype jaw crusher in which crushing speed, jaw clearance, jaw angle, ratio of feed size to jaw clearance, and feed rate could be varied. A crusher built with the optimum design characteristics crushed (U, Pu)O2 to the particle-size distribution that was predicted and desired.
