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.”

In the rare occurrence of a fuel failure during normal operation, the primary coolant can enter the element. Visual techniques are normally used for the postirradiation inspection of discharged CANadian Deuterium Uranium (CANDU) fuel bundles to help identify such failures. In this work, a more sensitive method, based on underwater angled-beam ultrasonic inspection, is investigated under laboratory conditions. Only nonirradiated fuel elements were tested. Identification is possible with the introduction of water into the fuel element, which acts as a couplant for sound waves, thereby providing for a clear demarcation of the fuel pellets within the element in observed scans. This study therefore demonstrates that the inspection of the outer-ring (i.e., higher-powered) elements in the complex fuel bundle structure is possible.
