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.”

This presentation describes some experiments to investigate the reemission of tritium from stainless steel planchets that had been submitted to a reference cleaning procedure, exposed to elemental tritium under well defined conditions and stored under air in closed vessels for a long period of time (months). The nature of the evolved species was studied in short desorption experiments consisting of flowing an air stream at ambient temperature past one of the tritium-bearing planchets. It was shown that a substantial part of the reemitted activity was in the form of volatile tritiated organic acids. It seems that these products, accumulated on the planchet during the storage phase, are subsequently available for desorption and emission to the atmosphere when the planchet is swept by air. The possible origin of these tritiated organic acids is further discussed.
