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 temporal behavior of electron density profiles of edge plasmas in the Compact Helical System (CHS) during high beta discharges was measured with a thermal neutral lithium beam probe. A large outward shift of the plasma edge boundary was observed with an increase in the beta value. The position of the plasma edge boundary measured experimentally was compared with that of the last closed flux surface (LCFS) calculated by the VMEC code, and qualitative agreement was found between experimental and theoretical results. The experiment on the dynamic poloidal field control during the discharge was also performed successfully to fix the position of the edge plasma boundary when the plasma beta was raised.
