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.”

MFTF-B is the largest fusion mirror device currently under construction. When completed in 1988 the mirror will be fueled and heated by 11 neutral beamlines whose combined power output will be over 40 MW. These beamlines are being designed and built by TRW Systems. Associated with each beamline is a vacuum system whose performance plays a crucial role in the operation of neutral beams. Good vacuum is needed in the injectors and dump tanks to limit the beam loss due to reionization and to avoid excessive gas flow into the plasma chamber. This paper will describe the design of these vacuum systems and explain the considerations and tradeoffs made in the process.
