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 collimator system of a neutron beam line that is used for neutron-nucleus reaction measurements has been designed. Collimators in the middle region are optimized using a Monte Carlo simulation so that the neutron dose in the shielded area is as small as possible. A collimator closest to the experimental target is designed based on several origins of neutron backgrounds studied by the simulation. The simulation data finally obtained show a favorable background level and an expected neutron beam at the target position.
