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.”

Gibbsian segregation has been observed in trinary alloy Al-Li-Mg. The experiment was carried out by means of secondary ion mass spectroscope (SIMS). The experimental results indicated that the lithium concentration on specimen surface reached approximately 100% in the specimen temperature region of 150 to 300 C. The depth profile of Li showed that there was some broadening resulting from recoil implantation by high energy Ar+ ion bombardment. When the specimen temperature exceeded the temperature range in which the lithium enrichment reached the maximum value, beryllium, impurity element in the alloy, segregated to the surface and competed with lithium. Irradiation-induced segregation for Be was also observed in the experiment.
