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.”

Phase IIC of the experimental program is to begin in fall of 1988. An extensive pre-analysis has been carried out to select the experimental configurations. The investigations were confined to looking at the effect of (i) multi-layer arrangement of Be multiplier, (ii) the presence of contiguous layers of structure and coolant, (iii) the introduction of protective graphite armor in front of the first wall, on tritium production rate (TPR) in a Li2O assembly. The basic materials and geometrical structure of the assembly, are derived from that of the Phase IIA. The structure is simulated by stainless steel (SS) and the coolant is either polyethylene (PE) or water. Generally, the heterogeneities strongly distort the local T6 and T7 distributions; their effect on global TPR is less marked. One of the two selected configurations has Be, in edge-on layered arrangement with Li2O, as multiplier. In the second configuration, three coolant channels (SS+PE) will be incorporated to simulate structural heterogeneity.
