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.

Geologic repositories for the long-term storage of spent nuclear fuel (SNF) are limited in their capacity by the amount of decay heat emitted by the SNF. The largest long-term contribution to this decay heat comes from the transuranics (TRUs), the destruction of which could increase storage capacity by a factor of at least 10. A design concept for a subcritical gas-cooled fast transmutation reactor (GCFTR) fueled with TRUs from SNF is being developed. This paper presents the results of analyses of several GCFTR fuel cycle scenarios that have a deep-burn (>90% burnup of the TRU fuel) primary objective and a secondary objective of avoiding reprocessing of the TRU fuel if possible.
