band. RCIC operation is not required.
B. Start RCIC manually and then secure HPCI. Increase reactor water level to the
normal operating band. All required PCIS Group isolations have occurred.
C. Reset the Group 2 isolation immediately to prevent high drywell pressure and
continue to monitor HPCI while restoring reactor water level to the normal band.
D. Isolate the RWCU System, start RCIC manually, if possible, and continue to

Depressurization if 2 or more areas exceed the Maximum Safe Operating Temperature
and a primary system is discharging reactor coolant into secondary containment.
Which ONE of the following statements explain the reason for this action?
A. The rise in secondary containment parameters indicate a wide-spread problem
which may pose a potential threat to secondary containment integrity or preclude
personnel access required for the safe operation of the plant.
B. The rise in secondary containment parameters indicate substantial degredation of
the primary system and may lead to fuel failure if the leaks are not isolated.
C. The rise in secondary containment parameters indicate a wide-spread problem
which may pose a direct and immediate threat to secondary containment integrity or
equipment located in secondary containment.
D. The rise in secondary containment parameters indicate substantial degredation of
the primary system and emergency depressurization effectively isolates the leak.
