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 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. 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.”

On the Large Helical Device (LHD), improved confinement of fast ions by moving the magnetic axis location inward is theoretically predicted. This improvement is observed significantly in the fast-ion tail formation during the experiments of ion cyclotron range of frequency heating. The fast-ion loss effect on the tail formation is 10 times more significant in the standard configuration than in the inwardly shifted configurations. The superiority is also confirmed by the comparison of steady-state fast-ion spectra for the neutral beam (NB)-heated plasmas and by the flux decay of fast neutrals after the short-pulse injection of radial NB.
