Operating crew entered abnormal operating procedure for feedwater malfunction when SG #3 level began rapidly lowering. Operators attempted to take manual control of SG #3 main feedwater regulating valve and were unable to raise SG #3 level. SG #3 level lowered to the Lo-Lo Level setpoint causing an automatic reactor trip. All control rods fully inserted and SG #3 level remained off scale low on narrow range indications. Auxiliary feedwater and feedwater isolation actuated as expected. (Unit 2) is currently stable in Mode 3 at normal operating temperature and pressure. A forced outage response team has been formed to determine the cause of the low SG water level and determine restart criteria and time of restart.</br>All control rods fully inserted on the trip. Decay heat is being removed via auxiliary feedwater to steam generators steaming to the condenser steam dumps.</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector. +
