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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

The development of radiation-resistant materials to sustain the harsh fusion environment represents a challenging task for divertor designers. In recent years, advanced physics simulations of the power leaving the plasma with radiation and charged particles indicate much higher heat fluxes to the divertor than previous estimates. In response, experts in EU, Japan, and US developed several W alloys for advanced He-cooled divertors that can handle heat fluxes in excess of 10 MW/m2. This paper briefly discusses the ongoing effort to develop W alloys suitable for fusion applications, the challenging phenomena impacting the behavior of W under a fusion environment, and the environmental impact of the most promising, state-of-the-art alloys: W-La2O3 and W-1.1TiC.
