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.”

The main objective of the 1992–93 shutdown has been the installation of a pumped divertor inside of the JET vacuum vessel. Apart from the divertor components, comprising four poloidal field coils, a cryopump, and a new target structure. The belt limiters and continuous inner wall have been replaced by poloidal limiters, there is a completely new design of RF antenna, and a system of internal actively controlled saddle coils for disruption feedback stabilisation has been installed. External to the vessel there have also been some major updates to the hardware and plasma control systems, with a new fast radial field amplifier for vertical stabilisation, and a decoupling control scheme for the poloidal circuits. The as-built status of the plant and some results of the initial operation are described.
