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.”

The use of fiber composite technology and finite element analyses on both micro- and macro-scale, can bring innovative solutions to the design of the divertor plate for future experimental fusion reactors. Overall divertor problems are discussed. An original and versatile solution is proposed and some promising results from a thermo-mechanical analysis are presented, using two- and three-dimensional modelling and a realistic heat flux profile, without separatrix sweeping. The effect of the third dimension is focused in this paper. Emphasis is also put on the integration of the micro- and macro-scale results. Finally inherent design improvements and weaknesses are discussed; the preliminary balance is highly positive.
