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.”

Organically bound tritium (OBT) transfers into human body via food chain. ICRP report recommends that the dose due to OBT ingestion is 2.3 times higher than that due to HTO. Thymidine is a specific precursor of DNA. There were several reports on ingestion experiments of OBT including 3H-thymidine. However, the concentrations of tritiated compounds used in those experiments were extremely high compared with environmental tritium concentration. Therefore, in this study, we used tritiated compounds with 100 times of concentration based on the highest concentration in rain after nuclear tests during the 1960's, i.e. 700 Bq tritium/l rainwater. Mice were chronically fed with each one of tritiated organic compounds, 3H-thymidine, 3H-leucine, 3H-glucose or HTO for comparison, and the excretion and distribution of tritium in mouse body and tritium uptake into DNA in each tissue were determined at 180th, 240th, and 300th day of ingestion. Almost no significant differences were found between the dose rates from DNA-bound tritium throughout long-term exposure by ingestion of tritiated organic compounds and that of HTO.
