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.”

In a D-3He fusion reactor, direct energy conversion is expected, and discrimination of charged particles from each other is needed to produce electric power. The authors have performed simulation experiments for discrimination and direct energy conversion in a CUSPDEC device with a slanted cusp magnetic field. This paper presents a scaling of particle discrimination with proposition of an appropriate scaling factor based on the consideration of the Störmer potential. Experimental results with the factor up to 0.7 for ions and 80 for electrons are presented. The paper also presents results of direct energy conversion of ions in higher energy region up to 5 keV. It is confirmed that the conversion efficiency does not depend on averaged energy, but depends on the broadness of energy distribution function.
