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.”

Slow wave electron cyclotron maser composed of a periodically corrugated waveguide and an axially streaming electron beam is considered. This slow wave electron cyclotron maser can be driven by the electron beam with predominant axial velocity and is distinct from the conventional fast wave electron cyclotron maser, in which an electron beam having an initial perpendicular velocity to magnetic field is required. Normal modes in the cylindrical slow wave system with magnetized electron beam are analyzed by a linear fluid model, taking into account of three dimensional beam perturbations and boundary conditions self-consistently. The axially streaming electron beam is able to interact with periodic electromagnetic normal modes at an anomalous Doppler cyclotron resonance, resulting in slow wave electron cyclotron maser instability. When the frequency of the slow wave electron cyclotron maser instability coincides with that of conventional Cherenkov instability, two instabilities can be combined favorably to generate microwave radiation.
