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.”

Potential safety advantages are achievable through the use of advanced fuel cycles, which eliminate the need to breed and fuel tritium, and produce fewer neutrons. In this work, the operational radiological hazards associated with the deuterium-tritium (DT), deuterium-deuterium (DD) and deuterium-helium-3 (DHe) fusion fuel cycles have been compared. The advanced fuels have a clear advantage over the DT fuel cycle in terms of tritium hazard. In terms of activation and waste disposal hazards, the operational safety advantages of the advanced fuels are less clear, and appear to be strongly material dependent.a On assignment from the Canadian Fusion Fuels Technology Project (CFFTP).
