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 physics knowledge relevant to the design of a reactor-scale tokamak—the ITER Physics Basis—has recently been assessed by the ITER JCT, the ITER Home Teams, and the ITER Physics Expert Groups. Physics design guidelines and methodologies for projecting plasma performance in ITER and reactor tokamaks are developed from extrapolations of various characterizations of the database for tokamak operation and of the understanding that its interpretation provides. Both “conventional” and “advanced tokamak” operating modes are considered. The overall device parameters for ITER are found to be consistent with these guidelines. The plasma performance attainable in ITER is affected by many physics issues, including energy confinement, L-to H and H-to-L-mode power transition thresholds, MHD stability/beta limit, density limit, disruptions, helium removal, impurity content, etc. Design basis and guidelines are provided in each of these areas, along with sensitivities and/or uncertainties involved.
