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.”

Laboratory experiments show that when tri-n-butyl phosphate is heated with nitric acid or metal nitrates, chemical reaction generates gas mixtures that can spontaneously ignite. In closed vessels, ignition of these gases was observed at gas phase temperatures of 184 to 264°C, corresponding to liquid-phase temperatures of 158 to 225°C. Pressures of tens of megapascals were measured. Several accidents associated with Purex processing in the nuclear industry appear to have been caused by ignition of the products of this reaction, either inside or outside process vessels. Safety measures involve controlling the temperature and providing adequate vents.
