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.”

A nucleonic analysis of the Engineering Test Facility vacuum pumping (VP) duct shield has been performed using a coupled Monte Carlo/discrete ordinates method. This method used Monte Carlo to determine internal and external boundary surface sources for subsequent use in discrete ordinates calculations of the neutron and gamma-ray transport through the shield. Confidence in both the coupled method and the results obtained through its use was provided through comparisons with three-dimensional Monte Carlo results. Calculations in the toroidal plasma chamber and the neutral beam injector duct, which were required prior to the VP duct shield calculations, are also described.
