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.

The 31 and 81 keV x- and gamma-ray emissions, curie level specific activity, 5 day half-life, and reasonable cost make 133Xe an attractive source for use in cancer implantation therapy. The qualifications of 133Xe as an implantation source, and an analysis of shielding and absorption characteristics are discussed. A method for source fabrication using liquid nitrogen cryo-pumping and heat sealing of plastic tubing is described.
