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.”

Solutions for the RF heating problems in HANBIT mirror machine have been obtained by analytically under the assumptions of uniform plasma and magnetic field [1]. For the case of non-uniform plasma and magnetic field, a numerical calculation for entire region requires considerable computing times and delicate considerations of the antenna current. In this work, we developed a hybrid method in solving the RF heating problem in which the outer region of the plasma limiter including the antenna is treated by an analytic technique and the plasma region is solved by a numerical method. Solutions for two regions are matched on the plasma-vacuum interface self-consistently without loss of generality. Using this method, we can reduce the calculation time and required computer memories and present some results for HANBIT case.
