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 use of the large-area tokamak inner wall to reduce peak heat fluxes has been proposed as a potential alternative to the use of divertors. This paper uses detailed modeling of inner wall processes on several existing tokamaks to understand the differences among them and the cause for deviations from ideal performance. The present analysis shows that the typical deficiency in overall performance for inner-wall limited plasmas to date is largely sui generis: that is, each of the cases has unique performance-limiting features, rather than representing an intractable general problem
