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.”

Two heavy water upgraders have been developed and operated in the Fugen Nuclear Power Station to keep the isotopic purity of the moderator around 99.7 wt% and to recover tritium from the degraded heavy water. One of the upgraders is a combined electrolysis catalyst exchange (CECE) process that consists of 90 stages of catalytic water-hydrogen isotopic separation units. This upgrader treats 10 m3/y of degraded heavy water, produces reactor grade heavy water, and lowers the tritium and heavy water in the waste to <3700 Bq/cm3 and <0.1wt%, respectively. The other one is simple electrolysis system and terminated its operation in 1999. Heavy water recycle is completed with these two upgraders in the Fugen. A filter-separation-type tritium monitor was developed. Daughter species of Rn-Tn are separated from sampled gas with hollow fiber filters made of perfluorosulfuric-acid resin before introducing to an ionization chamber. The detection limit of the monitor is 7.4E-03 Bq/cm3-air. The upgraders and monitor contributed to control airborne and liquid tritium releases from the Fugen lower than 18 TBq/y and 11 TBq/y, respectively.
