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 Cryogenic Forevacuum System (CFV) of the JET Active Gas Handling System is designed to collect gas mixtures from the torus and injection systems. The CFV separates hydrogen isotope mixtures from helium and impurities and stores isotope mixtures for separation. All crucial process elements are located in all-metal secondary containments. Prototype tests on accumulation panels have shown the capability of pumping hydrogen/helium/impurity mixtures. A pumping speed of 12500 ℓs-1 has been measured for deuterium with mass flow rates up to 125 mb ℓs-1. Cryotransfer pumps were shown to pump typical batches of 100 ℓ (STP) H2 or D2 in 15 minutes.
