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.”

Developing robust and reproducible start-up scenarios is essential for all tokamaks and especially for burning plasma devices. A tokamak start-up sequence is complex and calls on control of different types of plasmas, from nearly collisionless low-temperature electrons in a large neutral background to a more conventional diverted high-temperature fully ionized plasma during the ramp-up phase.
