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.”

Catalyzed D-D is the ultimate fusion cycle, because deuterium is essentially unlimited on earth. In this approach, the 3He and tritium fusion products are recycled to increase the charged particle fusion power. A difficulty with this fusion cycle is that the tritium from fusion, if left in the plasma, produces 14-MeV neutrons, leading to radiation damage comparable to that of the D-T cycle. This paper shows that the damage problems may be alleviated by removing tritium before it can burn. Fortunately, the charged particle fusion power from burning the tritium is small compared to that from the 3He and removing it from the plasma makes little difference to the plasma power balance. Ion cyclotron power might be used to pump out tritium. In this paper, we review the benefits of tritium removal, identify the issues associated with this approach, and determine illustrative parameters required for an advanced tokamak and an advanced stellarator.
