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 new technique, Abel inversion for toroidal coordinates, is presented for calculating spatial distributions of an axisymmetric toroidal plasma density from observation beam incidents in the toroidal y direction. In this numerical method, inversion matrix elements are calculated analytically, and their usefulness is examined by using a hypothetical data set of beam intensity with asymmetry for the normal direction to the direction of observation, which results in a valid local plasma density. The asymmetrical character associates with fundamental fixed length dfor the toroidal coordinates.
