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 conversion reaction of tritium gas to tritiated water in dry air has been studied using low–concentration tritium gases which have three different hydrogen isotope compositions. The conversion was directly proportional to a ratio of radioactivity of T2 to that of total tritium. This demonstrates that the T2 decay process is predominant for the conversion reaction at low initial tritium concentrations. First-order rate constants for the reaction in dry air are found to be independent of initial tritium concentration. A model to predict the rate constant of the production of tritiated water from T2 in dry air has been developed. The modeling results show that the T2 decay process is predominant at low concentrations, while O+ and N2+ ions formed through tritium beta-ray induced reactions play important roles at high concentrations.
