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 overall control architecture serving the European Tritium Handling Experimental Laboratory (ETHEL) consists of two types of apparatus:1) Programmable Logic Controllers (PLCs), Personal Computers (PCs), networks which constitute the so-called Distributed Digital Control System (DDCS); 2) Fail-safe hard-wiring which operates independently of the DDCS. This paper deals with the first type of apparatus; its hardware and software are described. The computerized system, defined by a four-level hierarchical and modular architecture, is a large distributed Real-time Control System. The operation is mainly centralised in the Control Room through a fully programmable man-machine interface (graphic displays, trends, etc.).
