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.”

This paper describes a concept for a high performance, inherently safe fusion reactor blanket using helium coolant, beryllium multiplier, lithium breeder and a vanadium alloy structure. The goals of the design were to explore the possibility of inherent tolerance to loss of coolant and flow accidents while minimizing the cost of electricity. Results indicate high net thermal-to-electric conversion efficiency (45.5%), good energy multiplication (1.64) and excellent afterheat tolerance, with a maximum blanket temperature of 760°C after one year with no cooling. However, the calculated COE (0.0405$/kWe.h) is slightly higher than other blankets costed on a similar basis by the MINIMARS1 program because of the projected high cost of vanadium.
