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.”

JET progressively established elements of an environmental monitoring programme well in advance of tritium operation in order to determine baseline levels. Prior to the first JET tritium experiment (PTE) in 1991, an extensive programme was in place and agreed with the regulatory authority. This consisted of tritium in air, rain, ground and river water, and crops on and off the JET site. Air is sampled continuously and averaged monthly. Other samples are taken quarterly or, at an appropriate point in the growing season. The discharges of tritium from the JET stacks are monitored by on-line instrumentation and silica gel-based samplers. The performance of these is described and improvements arising from the PTE experience are discussed. In particular the implications of tritiated methane on sampling and analysis are considered. The results of environmental monitoring are presented and comparisons made with predictions from discharges made during the PTE and subsequent operations. The implications of washout on the site liquid discharge authorisation is considered. From a comparison of observed and predicted concentrations, routine releases of tritium from JET will have insignificant environmental impact.
