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 tritiated water vapour monitor that utilizes modulation of the input tritium concentration to allow phase sensitive detection is described. This measurement technique is useful in those measurement situations where there are slowly varying interferences from other radiations or species; or where it is necessary to measure quite low concentrations. The increased immunity to interferences is because, in general, the frequency spectrum of the interferences is peaked at zero frequency and will not have major components at the modulation frequency. The increased sensitivity of the monitor is because it is not limited by input leakage currents nor slow drifts in zero.
