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 presence of strong magnetic fields and of volumetric heat generation in the fusion reactor environment result in an unusual heat transfer situation for liquid metals, as compared to nonconducting coolants. The effects of velocity profiles and volumetric heat generation on heat transfer in liquid-metal blankets are examined both analytically and numerically. Analysis shows that unlike the fully developed Nusselt number, the spatial dependence within the entry region is relatively insensitive to the shape of the velocity profile and the amount of bulk heating. Hence, closed form solutions f or fully developed heat transfer can be used together with a normalized entrance region curve to estimate heat transfer throughout the blanket.
