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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

A scoping study was performed to explore tritium breeding and energy-temperature splits in various blanket concepts for high-temperature process heat. Temperature limits for the lithium materials necessitate two blanket zones. One delivers heat at moderate temperatures (≾600°C) and breeds tritium. The other is a nonbreeding zone that produces heat at high temperatures. We find that a system where all blanket modules breed tritium delivers more high-temperature heat than one where only some of the blanket modules produce tritium. Of those considered, a design where the high-temperature zone is placed between two breeding zones produces the highest fraction of high-temperature heat. When liquid lithium, Li7Pb2 and Li2O tritium breeding materials are employed with two breeding zones, a tritium breeding ratio of 1.1 can be achieved while delivering 30 to 40% of the blanket heat at high temperature.
