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.”

An overview is given of the research carried out by the French Atomic Energy Commission on the geological disposal of nuclear waste. Recalling the new legal framework of these studies, the specific methodology of this field, which relies on the association of laboratory and in situ experiments, natural analogues, and modeling is emphasized. Next are underlined the basic questions, which have to be reliably answered when one wants to predict the behavior of the repository and the fate of the most radiotoxic nuclides, in particular over very long time spans: What parameters govern the hydrodynamics and the geochemistry of the system? What are the processes controlling the degradation of the different technological and natural barriers, as well as the release, migration, and retardation of radionuclides through the geosphere? For each of these issues, the current programs of research are described and indications are given about significant achievements.
