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 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. 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.”

Distribution of carbon dust in the plasma discharges was measured, and sublimation of dust was dominant in the scrape-off layer (SOL). Dust collection in the vacuum vessel was performed after the experiment campaign, and the analysis showed that both weight and number of dust were large at the exhaust route of the deuterium gas under the divertor structure. Microscope analysis showed that small dust group (less than 20 m) had a statistical population, and that large dusts (larger than 20 m) contributed significantly to the total weight. Understanding of the properties of both small and large dusts is important to evaluate surface area for determination of fuel retention.
