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.”

Recycle of nitric acid in the UREX+ process requires removal of acetic acid. An analysis of the effects of acetic acid in each process step indicates no step will be significantly affected by the concentrations expected. Thus, acetic acid removal can be placed after the last salts are removed, just before the nitric acid is recycled. Two promising removal options have been considered, solvent extraction and distillation. Distillation requires removal of most of the water before large fractions of acetic acid are removed. The process would be energy intensive and would involve the handling of extremely concentrated nitric acid; therefore, solvent extraction appears to be more attractive.
