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.”

Some open traps, like GOL-3, may be heated by axial electron beams. Since the heating is turbulent, it is associated with anomalous resistivity, so that the reverse induction current is pushed out to flow in the shell plasma along the beam edge. It is shown that such complicated distribution of axial current in equilibrium causes exponential amplification along the trap of any initial (at entrance) azimuthal modulation of the beam current density. As a result, the shape of the beam cross-section develops features like spiral arms, etc. at the end-plate, even if its shape was nearly circular at the entrance. Amplification occurs whenever there is an off-axis extremum on the radial distribution of the axial current density.
