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.”

A real time control system has been developed to maintain an RF impedance match in the ion cyclotron range of frequencies (ICRF). This system is designed to adjust output parameters with a cycle period of approximately 100 useconds using commercially available VME based components and a UNIX workstation host. Advanced Ferrite Technologies (AFT) has developed the hybrid tuning system (HTS) which has the capability of tracking a mismatch on the time scale of milliseconds (2.5 MW, 60 MHz) by varying the magnetic field bias of ferrite loaded transmission lines. The control algorithm uses a combination of neural network and fuzzy logic techniques. Initial results of a test facility using a low power prototype are presented.
