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 Impurity Processing Loop (IPL) of the JET Active Gas Handling System is designed to recover tritium from impurities such as tritiated water and hydrocarbons present in the JET plasma exhaust. All impurities are fully oxidised in a catalytic recombiner, the tritiated water frozen in a cold trap and subsequently decomposed on hot uranium powder. Hydrogen isotopes set free in this reaction are scavenged from the helium carrier gas in a cold uranium bed. The modular design of the IPL permits implementation of advanced processing schemes (eg avoiding solid UO2 waste) in the future without major hardware modifications.
