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.”

All nuclear plant instrumentation connected at installation points to low-voltage power circuits will be exposed to electric fast transients induced by power switching and lightning. Unwarranted interruption of instrumentation due to transients may result in serious loss through bothersome activation of a plant's engineering safeguards. In this study, in situ responses of a digital wide-range neutron monitor is studied in terms of real-time disturbances during electric transients. Using correlation analysis, a systematic methodology between transient responses and steady-state electromagnetic emission spectra has been developed and justified to be useful for transient isolation. Moreover, results of various on-site approaches to improve the electromagnetic compatibility of safety-related instrumentation are discussed.
