On August 24, 2020 at 2305 CT at Grand Gul … On August 24, 2020 at 2305 CT at Grand Gulf Nuclear Station (GGNS) an Automatic Reactor Scram occurred after a trip of the Reactor Feed Pump B and subsequent lowering of reactor water level to 11.4 inches Narrow Range. The scram occurred with Reactor Power at 14% and the main generator offline.</br>All control rods fully inserted and there were no complications. All systems responded as designed.</br>Main Steam Isolation Valves were manually closed to control reactor cooldown, Currently GGNS reactor pressure is being maintained at 450-600psig. Reactor water level is being maintained with condensate through startup level control.</br>No radiological releases have occurred due to this event from the unit.</br>The NRC Resident has been notified.</br>Decay heat is being removed via the main condenser.</br>Notified R4DO.ved via the main condenser.
