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 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. 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 context of fusion reactor development, it is important to predict waste stream, efficiency of waste treatment and interaction between waste management and environment.This paper intends to summarize the experience of CEA in this field, gives some global ratios in technical environmental and economical terms, so that it can help for dimensioning or selecting treatment installations for other industrial plant. CEA has a complete management of tritiated waste, including cutting, melting in furnace, vapor decontamination treatment of organic waste and detritiation of glove boxes. Measurements of drums out-gassing are systematically performed. Relations between out-gassing and content are discussed. Ratios HT/HTO are presented. This experience shows that pure tritiated waste can be neutralized and managed with relatively few releases.
