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.”

Single and double sapphire spheres have been precisely suspended in 300 mg/cm3 RF aerogels without a supporting stalk by modifying parameters such as gelation time and stability of the aerogel precursor solution and use of a vacuum holder for the sphere placement. A process for fabricating a single-sphere target was also developed using a spider silk support (approximately) 100 times thinner than the earlier work on similar targets. Characterization of the ball placement and the aerogel was done by radiography. Data from the characterization of these targets showed that the ball was accurately placed and the aerogel matrix was not significantly altered.
