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.”

CO2 pumped FIR (Far Infrared) lasers have a number of valuable uses in the diagnostics arena of fusion research. To maintain lasing, the tuning of the two lasers must be tightly coupled. This coupling presents interesting control problems. A number of analog approaches have been employed to implement tightly coupled tuning control. Such implementations, however, suffer from a lack of flexibility. A new digital controller has been developed that greatly increases the range of control strategies that may be implemented. Of further interest is the controller's capability to provide 96dB of dynamic range when driving −200V piezoelectric transducers. This paper will discuss the algorithms and hardware used in this controller. Lessons learned from the development effort will presented.
