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 dependence of neutron generation on the discharge current as well as the voltage in an IEC device is studied experimentally. We consider that the fusion events mainly occur between the accelerated ions and the background neutral gas from the linear dependence of neutron yield on the discharge current. The result of neutron generation proportional to the 3/2 power of the applied voltage indicates that the current within the hollow cathode may be limited by space charge. The particle simulation shows that the perveance in the experiments satisfies the conditions for space charge limited current.
