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 laser driver system we describe is coupled to the SOMBRERO reactor concept. This is the Inertial Fusion for Energy (IFE) design concept generated by the W.J. Schafer Team for a recent DOE study1. The nominal plant design has 1 GW electrical output and requires a KrF laser driver system that supplies 3.4 MJ per pulse onto a spherically symmetric, direct drive target, at a repetition rate of 6.7 pps. We describe an architecture which results from the constraints of what must be supplied at the target, coupled with a final amplifier design which makes use of e-beam pumped, angularly multiplexed, 60 kJ final amplifier cavities, recent technology advancements in e-beams and pulsed power, and which has been optimized for system efficiency. Driver system efficiency of more than 7% (“wall plug”), and an effective efficiency of more than 9%, obtained through utilization of laser waste heat, are projected.
