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 benefits and limitations arising from the use of polarized deuterium-tritium fuels were assessed for commercial tokamak fusion reactors. The difference in capital costs for a reactor with and without polarized fueling was quantified for two reactors, one with a beta of 0.067 and a major radius of 7 m and the second with a beta of 0.25 and a major radius of 5.25 m. The change in reactor performance was also quantified. The conclusion was that the sum of all benefits associated with the use of polarized fuels does not result in a significant improvement in the tokamak reactor economics.
