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.”

The main goal of this assessment is to classify the radwaste stream of the recyclable transmission lines (RTL) at the end of the Z-Pinch plant operation. With the emergence of the new clearance standards, we included both the national and international standards in our analysis and assessed the implications for the RTL waste stream. The 3-D spectral flux was coupled to the ALARA pulsed activation code to estimate the activation responses. Our results indicate that for the first time an internal component close to the target, such as the RTL, can be cleared from regulatory control following a storage period of 50 y after plant decommissioning. As a design requirement, the recycling process must be economically feasible, accomplished within 1.1 day with no hands-on manufacturing and in the absence of personnel access to the fabrication facility. Advanced remote handling equipment must be developed to handle a dose rate of 3000 Sv/h.
