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.

Design and procurement of the ICRF heating plant for JET began in 1982 on the basis that ten 3 MW generator-antennae units would ultimately provide the 15 MW of effective ICRF heating required in the JET programme. Three of these generator-antennae systems are already operational on JET; 6 MW of RF power has been coupled to the plasma with coupling efficiencies of between 50% and 90% depending on the antennae configuration. Taking advantage of experience gained and recent developments in RF tetrodes, JET is currently revising the antennae design, upgrading the generator RF outputs and now intends to install eight 4 MW generator-antennae units with consequential savings in cost and space in the JET vessel.
