Q

The plant is in MODE 5 at 190°
F with a plant heatup in progress.
Electrical Maintenance informs you that #1 CCW Pump Room Ventilation fan has a bad motor
ground.
They estimate it will take eight hours to repair.
Which ONE of the following describes the MINIMUM actions required for these conditions?
A. Continue with plant heatup, but do NOT exceed 250 degrees fahrenheit until the fan motor is
repaired.
B. Continue with plant heatup, since the fans are 100% capacity and only one is required.
C. Stop the heatup until the outside air dampers are failed open to allow maximum air volume
exchange in the room.
D. Stop the plant heatup, since each fan is required operable for its associated CCW Train to be
operable.

Q

Which ONE of the following statements correctly describes the Component Cooling Water cooling
to the Control Rod Drive System?
A. CCW cooling is isolated when the reactor is tripped.
B. At RCS temperatures greater than 200°F, CCW flow modulates to maintain 180F.
C. To close the CRD trip breaker A and B, CRD booster pump flow must be greater than 146
gpm.
D. At RCS temperatures less than 220°F, CCW should be isolated to CRDMs when the drives
are de-energized to prevent condensation on the CRDM windings.

Q

You have just completed placing the second Spent Fuel Pool Heat Exchanger in service at the
Primary Reactor Operators request.
The Control Room contacts you on your radio and informs you that due to operator error in refilling
#3 CCW pump, the CCW surge tank level has dropped to 43 inches but is now stable.
Which statement is correct concerning plant status.
A. The CCW Surge Tank level drop is due to improper venting of Spent Fuel Cooling Pumps.
B. Since both Spent Fuel Pool Heat Exchangers are in service, adequate cooling exists for the
current conditions.
C. The CCW surge tank must be refilled in order to restore normal cooling to the Spent Fuel Pool
Heat Exchangers.
D. Although #1 CCW pump has AUTOMATICALLY tripped due to surge tank low level, #2 CCW
pump will still be able to supply cooling water to the Spent Fuel Pool Heat Exchangers.
