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.”

A 4667-second long discharge has been obtained in the ATF torsatron. The total amount of the energy input was 330MJ. The set-up procedures, the control of plasma parameters, and the effect on the wall conditioning for the long pulse discharge are reported in this paper. Fast density feedback control is not useful for a long-pulse operation; control of the neutral pressure on a slower time scale is necessary. Long-pulse discharges are quite effective for wall conditioning. Valuable experiences have been accumulated in the future experiments planned for LHD.
