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.”

Loss of alpha particles from compact torsatron reactors with M = 6, 9, and 12, where M is the number of field periods, is studied. The direct loss is a relatively weak function of radius and energy and varies from ≃33% for M = 6 to ≃18% for M = 12. Loss of alpha particles through scattering into the loss region is calculated using the Fokker-Planck equation and is found to contribute an additional alpha-particle energy loss of ≃15%. The consequences of these relatively large losses for torsatron reactor design are discussed. A figure of merit that characterizes the orbit confinement for a magnetic configuration is deduced and used to show how the direct alpha-particle losses might be reduced.
