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.

Applicability of Li2O pebble type breeder has been investigated. Current experimental and analytical studies reveal that problems of thermal stress cracking and vaporization mass transfer can be resolved. Design feasibility studies of Li2O pebble type blanket have been performed for the FER and a power reactor. Results show that Li2O pebble breeder makes it possible to design blankets with high breeding ratio and high breeder integrity which can satisfy design requirements with some allowance for uncertainties or variations of parameters.
