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.”

Articles are hosted by Taylor and Francis Online.
The machine design, power supply, and machine protection, as well as the different heating systems installed at ASDEX Upgrade are discussed. The available auxiliary heating power of 30 MW, supplied by three different heating systems, allows the power deposition to be varied and species heated over a large range. These three heating systems - neutral beam, ion cyclotron, and electron cyclotron heating - are presented in detail. A description of the pellet refueling system is included, which is successfully used for density control.
