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 fusion safety experiment was conducted to determine the consequences of water injection into high-temperature lithium-lead alloy under postulated reactor accident conditions. The temperature and pressure response, fraction of water reacted, quantity of hydrogen produced, and behavior of radioactive species associated with the use of this alloy as a breeder material were determined. The reaction products were identified and the aerosol was characterized for particle size, chemical composition, and deposition rate. The water injection was shown to be self limiting for a blanket module designed to withstand the pressure of the water coolant. Radioactive doses associated with the aerosol release from a high-temperature alloy breeder module were determined to be several orders of magnitude below the dose limit for acute health effects. The results were compared to previous experiments and recommendations were made.
