| event text = At 0010 [CDT], 04/04/2017, the reactor was manually scrammed from approximately 75 [percent] core thermal power due Condensate Storage tank level lowering to 24 feet. All control rods fully inserted and all systems actuated and operated as designed. No safety relief valves actuated. Reactor level and pressure are currently being controlled within normal bands. RCIC [reactor core isolation cooling] was manually initiated for level control. | | event text = At 0010 [CDT], 04/04/2017, the reactor was manually scrammed from approximately 75 [percent] core thermal power due Condensate Storage tank level lowering to 24 feet.
