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 methodology that combines the Eulerian/Lagrangian droplet flow model and the droplet impingement erosion model is proposed in this paper to qualitatively predict the distributions of wall thinning locations on the shell wall of feedwater heaters (FWHs). This hybrid computational fluid dynamics model can simulate the three-dimensional distribution of steam flow and the rebound characteristics of droplets within the FWH shell. Coupled with the droplet flow characteristics, an appropriate indicator derived from the droplet impingement model is used to calculate the possible locations of severe wall thinning. The predicted wear sites on the shell wall correspond well with the plant-measured ones. Based on this good agreement, the methodology proposed herein might be used to help construct the monitoring project of wall thickness measurement for FWHs in the power plant, especially in the measuring areas on the shell wall.
