Description:
At the completion of actions for the failure of RBM Channel No. 8, a trip of the No. 12 Circ Water pump will occur. This will cause condenser vacuum to start decreasing. The crew should enter the abnormal procedures for reduced circ water flow and lowering condenser vacuum. The CRS should direct the OATC to perform a rapid power reduction to aid in holding condenser vacuum. With Recirc reduced to minimum condenser vacuum will start to recover and power reduction can stop.
Time Position Actions or Behavior RO Determines core flow is > 26 Mlbm/hr.
RO Notifies CRS of actions taken.

Description:
After the crew has performed the rapid power reduction and addressed the loss of the circ water pump, then a loss of turbine bearing oil header pressure will occur. Header pressure will slowly begin to lower and eventually cause a low pressure to alarm. The BOP operator will respond to the annunciator procedure and start the AOP and TGOP. This will cause header pressure to begin to rise but should only reach approximately 22-25 psig. The annunciator procedure will direct them to take the main turbine off line if pressure cannot be restored to above 30 psig.
In-plant operators will report that there is a large lube oil rupture in the turbine building.
Time Position Actions or Behavior Simulator TRG #4: When the actions for trip of the No. 12 Circ Water Pump are completed or when Operator directed by the Chief Examiner, insert event trigger #4 to cause a rupture of the turbine bearing oil header.

RO Monitors plant parameters.
RO May manually scram the reactor based on plant conditions or as directed by CRS.
NOTE: If the crew does not manually scram the reactor and decides to shutdown the Turbine Generator per C.3, SHUTDOWN PROCEDURE, then the reactor will automatically scram due a loss of oil pressure to the TCVs and TSVs.
