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.”

In this paper, a pressurized lobular blanket configuration is neutronically optimized. The blanket configuration features the use of beryllium and LiAlO2 solid breeder pins in a helium-cooled cross-flow pattern. One-dimensional neutronic optimization calculations are performed to maximize the tritium breeding ratio (TBR). The procedure involves spatial allocations of Be, LiAlO2, 9-C (low-activation ferritic steel), and He, in such a way as to maximize the TBR subject to several material, engineering and geometrical constraints. Consistent with all imposed engineering constraints, a TBR of 1.17 is achieved for a relatively thin blanket (≃43 cm depth).
