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.”

The Tokamak Fusion Test Reactor (TFTR) Preliminary Decontamination and Decommissioning (D&D) Plan1 was developed to provide a framework for estimating the costs and schedule for implementing a final D&D Plan. This work will be used in evaluating the future use of the TFTR Test Cell. D&D planning and estimates were generated for two cases of plasma operations for TFTR. The first scenario is for continued operation in deuterium-deuterium (D-D) plasmas and subsequent decommissioning. This scenario would require D&D to a TFTR which is slightly activated and contaminated but still with a capability for “hands-on” D&D work. The second scenario calls for deuterium-tritium (D-T) plasma operations. In this scenario TFTR becomes highly activated and contaminated with tritium. This operational scenario will result in a TFTR which will require D&D involving remote handling. The end result in either scenario would provide a Test Cell which is available for future use. This paper will discuss the D&D objectives, management, safety and technical plans, and critical assumptions made in order to develop cost and schedule estimates.
