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.”

Effects of beam convergence on fusion reaction rate in the cylindrical IECF device are investigated using 2-D simulation code by changing electrode shape. Simple simulation well reproduces experimentally obtained dependences of neutron production rate vs. discharge voltage and current, and it is found that almost all reactions occur by beam-background gases collisions, not beam-beam collisions. Results show that fusion reaction rate increases significantly with increase of beam convergence, therefore, increase of ion densities in the center, even in the devices where beam-background gas collision is dominate.
