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.”

In 1966, the Stevens Institute of Technology (SIT) plasma focus group demonstrated experimentally that the current sheath of the plasma focus is carried by pairs of plasma vortex filaments, which exhibit a force-free, Beltrami-type morphology. Experiments at SIT in 1980 and at the Air Force Weapons Laboratory (AFWL) show that relativistic electron beams traveling through a background gas of ∼1 Torr, and even in a “vacuum” diode, exhibit the same type of filamentary morphology, but on a spatial dimension scale, which extends down to the 1-µm region. Some of the experimental evidence accumulated in work at AFWL from 1979 to 1981, which supports the statement that there is a close similarity between current-carrying morphologies of the plasma focus and the relativistic beam machines, is presented.
