Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.”

In the new Replacement Tritium Facility (RTF) at the Savannah River Site, gloveboxes and stripper systems are used to minimize tritium release to the environment. The RTF was built to handle kilogram levels of tritium. It was started up and has been in operation since January 1994. The glovebox-stripper system has performed well in confining tritium leaks from the process. The tritium level in the gloveboxes has been maintained at below 0.1 Ci/m3 under normal conditions. During a large leak of tritium gas from the process to a glovebox, the tritium concentration in the glovebox shot up to about 4000 Ci/m3. However, there was no significant release of tritium to the environment. The tritium reading in the glovebox decreased to a 10 Ci/m3 level after 6 days of stripping. The performance of the glovebox-stripper system during this tritium leak and the possible factors for the long and slow decay of the tritium concentration in the glovebox are discussed in this paper.
