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 numerical investigation has been conducted to analyze the fluid dynamic aspects of the porous wetted wall protection scheme for IFE reactor first walls. A level contour reconstruction method has been used to track the three-dimensional evolution of the liquid film surface on porous downward facing walls with different initial film thickness, liquid injection velocity through the porous wall, surface disturbance amplitude, configuration and mode number, liquid properties, and surface inclination angle. Here, we report on the effects of evaporation and condensation at the liquid film surface on the dynamics of film flow, the free surface topology, the frequency of liquid droplet formation and detachment, the minimum film thickness between explosions, and the equivalent diameter of detached droplets. Generalized charts, which allow designers of conceptual IFE reactors to identify appropriate "windows" for successful operation of the wetted wall protection concept for different coolants are presented.
