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 work reported here attempts to: 1) define limits for the design windows for liquid metal breeders and coolants with various structural materials in various tokamak fusion reactors, and 2) quantify the impact of uncertainties in these limits on the design window. MHD pressure drop and heat transfer models are developed and used to quantify the effects of varying several tokamak reactor and blanket design parameters and materials properties. Uncertainties in the present pressure drop equations and calculational methods are also considered. Calculations are used to evaluate the impact of the coolant inlet temperature on the thermal cycle efficiency. An evaluation of the limits of uncertainty gives results ranging from a promising blanket candidate to a severely restricted design window, that would probably exclude self-cooled liquid metal blankets for large tokamaks from consideration. The major uncertainties in the design window result from the current lack of understanding of pressure drop and heat transfer in strong magnetic fields.
