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.”

Erosion and redeposition of sputtered material from a limiter and divertor were analyzed using the REDEP computer code. Both low- and high-Z materials were examined for a wide range of plasma edge temperatures. Redeposition rates are high in most cases, and net erosion rates are predicted to be much smaller than the gross rates. The limiter front face and the entire divertor plate have similar erosion properties. The lifetime of both surfaces depends critically on the redeposition process; under certain conditions relatively long lifetimes may be obtainable.
