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.”

A fusion neutronics benchmark experiment on vanadium-alloy was conducted. Various nuclear quantities related to both neutrons and gamma-rays were measured. It was found through benchmark analyses that all the cross section data of mainly vanadium in recent nuclear data files still involved serious problems. Improvement of these data is strongly required. According to discussion on neutron KERMA factors, the major finding was that neutron KERMA factors based on ENDF/B-VI above 10 MeV were too large due to the larger 51V(n,n'p)50Ti cross section.
