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.

An intelligent alarm-processing system for boiling water reactor (BWR) power plants is developed, to mitigate information overload for operators. To optimize the amount of information for disturbance detection, efforts are focused on alarm handling. The functions of the system are (a) to extract relevant alarms from the large number of alarms in the control room and (b) to provide the operators with a clear overview of the process status. The constituent methodologies for alarm handlings are realized by using logical expression and are implemented with a process computer. The test results of the system using a full-scope BWR plant simulator are quite satisfactory.
