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 steam explosion is the result of the intense heat transfer that can occur when a cold and volatile fluid is brought into contact with a hot fluid. This heat transfer is linked to the fine fragmentation of the hot fluid, so on the explosion timescale, only part of the cold fluid is involved in this heat transfer. In this paper, two different ways of describing this heat transfer are presented. In the first one, i.e., the microinteraction concept, the amount of coolant involved is controlled by the fragmentation kinetics, while in the second one, it is controlled by phase change resulting from interfacial heat balance.
