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 Polywell™ spherically convergent ion focus concept for controlled thermonuclear fusion is described. The device magnetically confines electrons by a quasi-spherical-cusp magnetic field, forming a potential well. Ions are electrostatically confined by this well, converging to a dense focus in the center of the spherical potential, where the fusion rate is large because of the high local density of transient energetic ions. Power balance and critical physics issues are outlined, along with current experimental and theoretical work. The potential of the device for D-3He operation is described by the derivation of scaling laws for energy gain.
