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.”

Radiation measurements were made during recent high power, high neutron yield experiments, and used to calibrate the neutronics simulation of the radiation shielding system. The results indicate that the present radiation shielding is more effective than predicted by the initial design estimates. This is attributed to the effects of changes in the experimental configuration since the initial design and to the design margin included to accommodate initial uncertainties in material properties and distributions. With the present radiation shielding, the production of 5 × 1020 D-T neutrons/yr will result in a total annual dose equivalent at the PPPL property line of less than the 10 mrem/yr design objective.
