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.”

Dust-air two-phase flow characteristics in a fusion experimental reactor during a loss-of-vacuum-accident (LOVA) event were analyzed numerically by three dimensional simulations using a newly developed thermal-hydraulic analysis code. Physical models on the motion of dust were considered to resolve the dust mobilization conveying by the fluid. Air ingress behavior through a breach at the LOVA event was calculated by using compressible Navier-Stokes equations. It was predicted quantitatively from the results of the present numerical study that the dust mobilization receives strongly the effect of the breach size and the fraction of the mobilized dust is determined by a circulating flow and buoyancy-driven exchange flow which are generated in a vacuum vessel of the fusion experimental reactor after the LOVA event.
