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.”

For estimations of the ingestion dose of tritium the dynamic behaviour of organically bound tritium (OBT) is studied in the framework of safety considerations for the nuclear fusion technology. In diet relevant plants, uch as wheat, the formation of OBT and the subsequent translocation into the seeds, till the time of harvest have been investigated in chamber experiments. Sets of field data on photosynthesis, transpiration and stomatal resistances at individual plants during several vegetation periods have been collected by gas exchange measurements. These data were used to test the recently developed model ‘Plant-OBT’. The paper analyses the results of comparisons between calculated and observed tritium concentrations in wheat plants after short-term exposures to atmospheric tritiated water (HTO). While the final OBT concentrations in the grains can be Simulated sufficiently, the modelling of the OBT formation and turnover processes in the leaves seems unsatisfactory so far. The unsolved problems in the recent OBT modelling approach are discussed.
