• Service Water Pump P-7C is in standby.
• Service water header pressure is 80 psig.
To prevent P-7B from being run at significantly reduced flows, the CRS directs the
NCO to secure P-7B. When Service Water Pump P-7B is secured header pressure
lowers to 45 psig, Service Water P-7C starts, and header pressure returns to 80 psig.

Non-critical Service Water header has been isolated.
• Service Water Pumps P-7A and P-7C are in-service.
• Service Water Pump P-7B is in standby.
• Service water header pressure is above 80 psig.
Due to the low flow conditions the CRS directs the operator to secure P-7C. When
Service Water Pump P-7C is secured critical service water header pressure lowers to
45 psig. Service Water Pump P-7B did not start.

- The plant is in MODE 5.
- PCS is at 623’ with S/G nozzle dams installed.
- The Shutdown Cooling System is controlling PCS temperature at 103°F.
- T-91, Utility Water Storage Tank, batch release is in progress
- The batch release calculation assumed two Service Water Pumps in operation.
- Main Condenser East and West Waterboxes are open for installation of a
modification.
- Service Water Pumps P-7A and P-7B are in service.
- Service Water Pump P-7C is tagged out for bearing replacement.
- Both Cooling Tower Pumps P-39A/B are available, but not in service.
- The Canal Sample Pump is in service.
The Secondary AO reports that the basket strainer on P-7A discharge appears to be
clogging as indicated by differential pressure trending steadily upward. A crew brief is
held to discuss removing P-7A from service to disassemble and clean the basket
strainer.

filled. Establish 15 minute periodic sampling of batch release flow
C. Plant will have Required Actions per LCO 3.7.8 Service Water System. Terminate
the batch release before stopping P-7A
D. Plant will have Required Actions per LCO 3.7.8 Service Water System. Start a
Dilution Water Pump before stopping P-7A

Answer 26

A. Plant will have Required Actions per LCO 3.4.8 PCS Loops - MODE 5, Loops not
filled. Terminate the batch release before stopping P-7A
Correct - The Service Water LCO does not apply below MODE 4. The batch
release requires that the dilution flow requirements be met. Securing a Service
water pump would violate these requirements and require that the batch be
secured while the release calculations are updated. In Mode 5 with the loops not
filled two SDC trains are required to be operable. To be operable each train
needs to have a separate SW pump. With only one pump operable only one train
could be considered operable.

manual handwheel. CCW Hx Service Water Outlet CV-0826 .
A. fails to full open position.
B. opens to a preset “hardstop” to provide maximum cooling for containment spray
and safety injection recirculation flow.
C.fails AS IS because the motor is not copuled when in manual handwheel.
D. closes to prevent a CCW pump runout condition from occurring.

Answer 43

C.fails AS IS because the motor is not copuled when in manual handwheel.

Question 44

The plant is on day 30 of a refueling outage. Due to main generator maintenance the
Non-critical Service Water header has been isolated.
• Service Water Pumps P-7A and P-7C are in-service.
• Service Water Pump P-7B is in standby.
• Service water header pressure is above 80 psig.
Due to the low flow conditions the CRS directs the operator to secure P-7C. When
Service Water Pump P-7C is secured critical service water header pressure lowers to
45 psig. Service Water Pump P-7B did not start.
Is this the correct service water pump response and why?
A. No, P-7B should have started at 40 psig discharge pressure on either of the other
pumps.
B. No, P-7B should have started at 45 psig header pressure.
C. Yes, P-7B should not start since P-7C was manually secured.
D. Yes, P-7B should not start until header pressure reaches 40 psig.

Answer 44

A. No, P-7B should have started at 40 psig discharge pressure on either of the other
pumps.

Question 45

Which one of the following describes the position of the Containment Air Cooler
Service Water inlet and outlet valves for a complete loss of Instrument Air and why?
A. VHX-4 inlet and outlet are closed; VHX-1, 2, 3 inlet and outlet are open. This
provides maximum cooling on a loss of instrument air.
B. VHX-4 inlet and outlet are closed; VHX-1, 2, 3 inlet and outlet are open. VHX-4
isolates because it is not safety-related. VHX-1, 2, 3 valves have nitrogen backup.
C. VHX-4 inlet is closed; VHX-1, 2, 3 inlet and outlet and VHX-4 outlet are open.
VHX-4 inlet closes because it is not safety-related. VHX-1, 2, 3 and VHX-4 outlet
have nitrogen backup.
D. VHX-4 inlet is closed; VHX-1, 2, 3 inlet and outlet and VHX-4 outlet are open. This
provides maximum cooling on a loss of instrument air.

Answer 45

Will have to look this up. will change later.

Question 46

Given the following plant conditions:
During power operations a Large Break Loss of Coolant Accident (LOCA) has
occurred.
A Safety Injection has occurred as designed.
A Containment High Pressure (CHP) also occurred as designed.
30 minutes later the Safety Injection & Refueling Water Tank level is at 1.8%.
What is the expected response of CCW HX E-54A SW Outlet CV-0823 and CCW HX
E-54B SW OutletCV-0826, and what is the reason for that response?
A. Failed AS IS to provide gradual cooling of the containment sump fluid.
B. Modulating to provide a gradual cooling of the containment sump fluid
C. Opened to a preset hardstop to provide maximum cooling for containment spray and safety injection recirculation flow.
D. Closed to preset hardstop to ensure maximum cooling water flow is maintained for Containment Air Coolers.

Answer 46

C. Opened to a preset hardstop to provide maximum cooling for containment spray and safety injection recirculation flow

Question 47

Which one of the following conditions will result in CV-1359, Non-Critical Service Water
Isolation, automatically closing? (Consider each condition separately.)
A. A fuel element failure results in Containment radiation reaching 12R/Hr.
B. A steam line break results in Containment pressure rising to 4.8 psig.
C. Service Water Bay level lowers to 568 feet.
D. Anticipated Transient Without a Scram (ATWS) occurs

Answer 47

B. A steam line break results in Containment pressure rising to 4.8 psig.
