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 Joint European Torus (JET) was initially built with metallic walls (Nicrofer 7612LC) and four graphite limiters. Gradually more and more graphite protection was added, and it now covers 50% of the wall. The inboard wall was covered with graphite tiles early in JET's operation to protect the wall from damage, and two toroidal belt limiters have been added to increase JET's power-handling capacity. Carbonization has been used as an additional tool to achieve certain benefits and has been developed at the Tokamak Experiment for Technically Oriented Research (TEXTOR) as a method to simulate, for a short time, an all-carbon machine and as a means to control density and impurity production. The benefits of the extensive use of graphite for protection and limiters and of the deliberate application of thin carbon layers are reviewed. Attention is given to the changes in the material under plasma exposure and the damage due to the plasma contact and the machine operation under those conditions. The role of the parameters of the scrape-off layer in the explanation and prediction of the plasma/wall interaction is emphasized.
