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 60-MW(electric) fast reactor concept, RAPID-A, without any control rods has been shown to achieve inherent safety and highly automated reactor operation and to provide reactivity control systems with maintenance-free and reliable performance over the plant design lifetime. RAPID-A is one of the variants of the refueling by all pins integrated design (RAPID), fast reactor concept, which enables quick and simplified refueling 2 months after reactor shutdown. In addition to the aforementioned advantages, unique challenges in reactivity control system design have been attempted in the RAPID-A concept. The design involves the following innovative reactivity control systems: lithium expansion modules for inherent reactivity feedback, lithium injection modules for inherent ultimate shutdown, and lithium release modules for automated reactor startup.
