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.”

Measurements of 14-MeV neutron leakage multiplication in lead are performed by the total absorption method. A polyethylene sphere is used as the neutron moderator and total absorber. Results from a 235U fission chamber and a 6Li glass detector are analyzed. The measurements are 7% lower than ANISN calculations using ENDF/B-VI.
