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 steam generator tube rupture (SGTR) incident occurred in Mihama Unit 2 on February 9, 1991. This is the first SGTR incident where the emergency core cooling system was actuated in Japan. With some measures being taken to improve the model, the precise simulation of the SGTR using RETRAN-02/MOD4 was conducted. A nonequilibrium model was applied to the secondary side of the damaged SG to obtain a reasonable response of the secondary pressure. The model of the reactor upper head was improved to simulate void generation during reactor coolant system depressurization, and there was good agreement with the actual plant data.
