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.”

The feasibility of spatial and temporal power density flattening in fusion-fission hybrid reactors was investigated by varying the concentration of 239Pu within a set of zones in the fission region and by examining two different fuel management schemes. Blanket designs with no 239Pu typically had a spatial maximum-to-average power density ratio of ∼2.5, but this value was reduced to between 1.26 and 1.67, depending on the design and fuel management scheme selected. Unfortunately, however, significant impact occurs only with relatively high fissile concentrations, with the outer zones approaching equilibrium values. Thus, either an impractically large fissile inventory for startup or long operating histories would be required.
