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.

Accuracy of earlier reported models for predicting liquid mixture viscosity for dry and water-saturated tri-n-butyl phosphate (TBP)/n-dodecane solutions is stated to be ±20%. Interaction parameters for the popular Grunberg-Nissan model have been computed, and liquid mixture viscosity has been modeled for a binary system of dry TBP/n-dodecane as well as the ternary system of water-saturated TBP/n-dodecane solutions at 298.15 K. In addition, dynamic viscosity of TBP has been modeled on the basis of an extension of the Andrade equation for an extended temperature range of 208.15 to 338.15 K.
