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.

Formation of fission-fragment etch pits in glass was investigated with emphasis on the application of the method to the measurement of uranium distributions in solids and low-flux neutron dosimetry. The application of the method to the determination of uranium distributions, in both small and large specimens, was illustrated with specimens ∼450 µ m in diameter and with large, uranium-doped cesium iodide crystals. Upper and lower detection limits for uranium and neutron fluence were established for the glass slides employed. The purpose of the research was to illustrate the applicability of etch-pit techniques to a range of problems in nuclear technology.
