,QUESTION 73 The plant has been scrammed following a complete loss of Turbine Building Closed Cooling.

Why does ONI-P44, Loss of Turbine Building Closed Cooling require starting the Reactor Core Isolation Cooling (RCIC) System?

_____ A. Main Steam Isolation Valves may close due to the loss of Instrument Air requiring RCIC for RPV Pressure control.

_____ B. Main Steam Isolation Valves will close due to high Main Steam Tunnel Temperature requiring RCIC for RPV Pressure control.

_____ C. Motor Feedwater Pump may become unavailable due to high bearing temperatures requiring RCIC as a makeup source of water to the RPV.

_____ D. Reactor Feedwater Pump Turbines will become unavailable due to high seal water temperatures requiring RCIC as a makeup source of water to the RPV.

QUESTION 74 The Control Room HVAC System (M25/26) is operating in the Normal mode when a radiological release from an unisolable Main Steam leak in the Turbine Building occurs.

The operator reports the following:

  • CR AIRBORNE IODINE D17-K777 has a HIGH alarm.
  • CR AIRBORNE GAS D17-K776 has an ALERT alarm.

Under these conditions, the Control Room HVAC System is operating in the:

_____ A. Normal mode with one train operating and the other train in standby.

_____ B. Normal mode with both trains operating.

_____ C. Emergency Recirculation mode with one train operating and the other train in standby.

_____ D. Emergency Recirculation mode with both trains operating.

QUESTION 75 The plant is operating at 50% reactor power when the following indications occur:
