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.”

Recently developed pulsed/intermittent irradiation calcu-lational models were used to analyze changes in the activity of major first wall constituents (aluminum, iron, manganese) due to changes in reactor pulsing schedules. Both magnetic fusion energy (MFE) and inertial fusion energy (IFE) experimental reactor systems were considered. Comparisons among pulsing schedules with equal neutron fluences demonstrated that the activities of some nuclides can be reduced to 28% of the values computed using a baseline pulsing schedule. This can be significant if the radionuclide affected dominates the total activity of the first wall.
