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.

Implantation-driven permeation (IDP) behavior of deuterium implanted with low energy (100–1800 eV) into 304 stainless steel has been studied. The experimental results showed that steady state permeation fluxes of deuterium through 304 SS decreased significantly with increasing the D+ ion from 100 through 1000 eV, while those above 1000 eV little depended on the energy. The energy dependence of the permeation flux observed would be attributed to change of the rate-determining regime of the permeation process depending on the incident ion energy.
