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 system has been designed to evaluate MPC level concentrations of 131I in reactor environments. The system provides reliable determinations of total 131I concentrations even under such unfavorable sampling conditions as high relative humidity or very low concentrations. Furthermore, the fraction of methyl iodide present can also be determined from the activity distribution on the several parts of the system. Field experiments were conducted at Consolidated Edison's Indian Point No. 1 reactor. The results of these tests are presented and discussed.
