Dy The turbine load increase was excessive, operators should stop the power increase.
Feedback DISTRACTORS:
A INCORRECT A reactor trip has NOT occurred. Panel XCP-615, 3-2 only requires 1 out of 3 channels to cause it to actuate. For a reactor trip to have occurred, 2 out of 3 channels would have had to trip which would have also caused Annunciator Point 3-5, OTiT, on Panel XCP-626 to actuate. Additionally, operators would not enter ATWS until after taking manual actions to trip the reactor and those actions had failed as well.
B INCORRECT A reactor trip should NOT have occurred. Panel XCP-615, 3-2 only requires 1 out of 3 channels to cause it to actuate. For a reactor trip to have occurred, 2 out of 3 channels would have had to trip which would have also caused Annunciator Point 3-5, OTAT, on Panel XCP-626 to actuate.
C INCORRECT A Turbine Runback and Rod Withdrawal Stop should not have occurred.
While Panel XCP-61 5, 3-2 only requires 1 out of 3 channels to cause it to actuate, for a Turbine Runback and Rod Withdrawal Stop to have occurred, 2 out of 3 channels would have had to trip which also could not have happened without causing both Annunciator Points 1-4 & 1-5, OPAT AUTO TURB RUNBCK W/DRWL BLCK, on Panel XCP-621 to actuate.
D CORRECT An excessive load increase would have caused this annunciator to actuate.
Although a number of other probable causes could have actuated this annunciator, each would have actuated other annunciators.

The plant is operating in Mode 1 at 100% power when a rod drop occurs.
Which ONE of the following describes the correct effect?
Ai/ Fuel temperature coefficient becomes more negative.
B.
Fuel temperature coefficient becomes less negative.
C.
Control rod worth increases.
D.
Power defect becomes more negative.
Feedback DISTRACTORS:
A CORRECT Negative reactivity is added to the core with the rod drop causing the fission rate to decrease and produce less heat in the fuel. The fuel temperature coefficient is the reactivity change that results from a change in the resonance cross section of the fuel due to a change of fuel temperature. As the temperature of the fuel decreases, the resonance peaks increase and the base of the peaks become more narrow. Although the total area under the curve stays the same, the number of neutrons in this region decreases.
This results in less neutrons being lost to the fission process through resonance absorption.
B INCORRECT Fuel temperature coefficient becomes more negative.
C INCORRECT Control rod worth decreases.
D INCORRECT Power defect becomes less negative.

A.
91 psig B.
100 psig C, 114 psig D.
128 psig Feedback DISTRACTORS:
A INCORRECT With the RB at atmospheric pressure, the rupture discs are set to release within the range of 86
- 100 psig (nominal release pressure is 91 psig).
Plausible since this is the nominal pressure.
B INCORRECT With the RB at atmospheric pressure, the rupture discs are set to release within the range of 86
- 100 psig (nominal release pressure is 91 psig).
Plausible since this is the minimum pressure plus containment pressure and also the max pressure with normal containment parameters.

D.
PT-445 has failed, perform the actions of AOP-401.4, Pressurizer Pressure Protection Channel Failure.
Feedback DISTRACTORS:
A CORRECT PT-444 failing high will cause (1) PCV-444B, PWR Relief, to open if in auto (2) both PCV-444C & D, PZR Spray valves, to open if in auto and (3)
Control and both Backup PZR Heater groups to deenergize. The P-i 1 trip status lights will light when pressure reaches 1985 psig. This failure is an entry condition for AOP-401.5.
B INCORRECT If PT-445 failed (high) it would cause (1) Both PCV-445A & B, PWR Reliefs, to open if in auto.
It would not cause either of the PZR Spray valves to open nor would it cause Control or Backup PZR Heater groups to deenergize.
C INCORRECT Although responding using this procedure would not be correct because none of the other entry conditions are present that would indicate a failure of a protection channel. An operator might select AOP-401.4 since one of the entry conditions for this procedure is an abnormal indication on P1-444.

The unit was operating at 80% power when a spurious low steamline pressure SI signal was received. The cause of the spurious signal was corrected and the SI signal has been reset.
During preparations to return the unit to power operations, the MSIVs fail to open when their control switches are taken to OPEN. The unit is currently in MODE 3 with steam pressure downstream of the MSIVs at 1080 psig and Tavg at 557°F.
Which one of the following is the cause for the MSIVs failure to open?
A.
The differential pressure across the MSIVs is excessive.
B.
The MSIV bypass valves are CLOSED.
C.
The Instrument Air header pressure is 75 psig.
D The MSIV isolation signal has not been reset.
Feedback DISTRACTORS:
A INCORRECT With pressure downstream of the MSIVs at 1080 psig and Tavg at 557°F (a SG saturation pressure of about 1104 psia), pressure across the MSIVs is essentially equal.
B INCORRECT MSIVs will not open unless the differential pressure across their seats is equalized. Although the bypass valves are normally opened in order to equalize pressure across the seats of the MSIVs, there is not an interlock between the two. The distractor is plausable in that an operator might confuse the operational aspect with an assumed interlock.
C INCORRECT The valves fail close when instrument air header pressure (or pressure felt on the MSIV actuator diaphram) drops to a certain level. While the actual value at which the valves will shut is probably < 60 psig, a value of 75 psig was chosen since it is lower than normal and will have caused both the standby Station Instrument Air Compressor to start as well as the Supplemental Instrument Air Compressor but is above 70 psig which may confuse operators as it places the plant in AOP-220.1, Loss of Instrument Air.
D CORRECT To open a MSIV after it has received an isolation signal, the signal must be reset by operating the trains A and B RESET pushbuttons.

The following plant conditions exist on Unit 1:
- The plant is at 90% rated thermal power
- All controls are in their normal configuration
- VCT level is at 50%
Which ONE of the following correctly describes how the plant would respond if VCT Level Transmitter LT-1 15 were to fail high with no operator intervention?
A. VCT level would lower until the VCT was approximately empty.
B.
VCT level would lower to approximately 5% and stabilize.
C.
VCT rate of level decrease would remain unchanged from the preevent rate of decrease.
D.
VCT level would lower to approximately 20% and then begin to rise.
Feedback KIA MATCH ANALYSIS:
The K/A requires testing knowledge of VCT level monitoring skills in conjunction with a loss of VCT makeup. LT-1 15 failing high would create a situation where LID would be diverted and auto makeup would not occur. The question is testing knowledge of how VCT level would respond in this situation; therefore, the K/A is met.
ANSWER CHOICE ANALYSIS:
A. Correct. Due to the failure, L/D would be diverted and auto makeup to the VCT would not occur. The VCT level would continue to drop (CCPs would eventually lose suction).
B. Incorrect. At 5% on LT-1 12 AND 115 the CCP suctions would auto swap to the RWST, thus making this answer choice incorrect. This swapover would close the VCT outlets, which would cause the VCT level to stabilize at approximately 5%. Plausible because the applicant must know that it takes a 2/2 coincidence to initiate the auto swapover.
C. Incorrect. Same reasons as B above. Plausible because at 10% the auto swapover signal clears. The applicant may associate the level at which the signal clears with the level at which auto swapover occurs.
D. Incorrect. Same reasons as B above. Plausible because this would be the correct answer if LT-1 12 were to fail high.

The reactor has failed to automatically trip when required and cannot be manually tripped. The turbine is tripped, the EFW pumps are running, and emergency boration is in progress. PZR pressure is 2385 psig. A malfunction in the control circuitry has caused PZR PORVs, PCV-445A and PCV-444B to fail to open. PZR PORV, PCV-445B, BLOCK valve is closed with its breaker open (pre-event condtion due to the PORV leaking). The crew has just closed the PORV BLOCK valve breaker and plan to open the PORV BLOCK valve.
Under the above conditions, which ONE of the following describes when the crew should open the PORV BLOCK valve and the reason?
A.
Immediately open the valve to prevent a rapid RCS overpressurization transient expected with most ATWS events.
B.
Open the valve just prior to the code safety lifting in order to prevent the code safety from lifting and thus preventing the possibility of the code safety valve sticking open.
C,P Immediately open the valve to allow enough borated water to flow into the RCS to ensure the addition of negative reactivity to the core.
D.
Immediately open the valve to begin a slow, controlled cooldown and depressurization, thereby minimizing positive reactivity feedback via a negative MTC.
Feedback DISTRACTORS:
A INCORRECT Overpressure limited by safeties. Opening PORVs wont prevent overpressure; they are assumed to operate for best estimate ATWS analysis.
B INCORRECT SGTR is not limiting (loss of FW is).
C CORRECT Requires trainee to analyze all conditions given and determine the limiting parameter.
D INCORRECT Depressurization doesnt affect + reactivity from negative MTC (procedure discusses allowing heat-up).

Ten minutes ago the crew completed a 6% per hour power ascention from 75% to 90% rated thermal power. A Pressurizer Safety Valve has just been identified as leaking to the PRT.
Which ONE of the following describes the affect on RCS temperature and Pressurizer water temperature, associated with the above events?
A.
RCS temperature will initially rise. Pressurizer water temperature will initially rise.
B. RCS temperature will initially rise. Pressurizer water temperature will initially lower.
C.
RCS temperature will initially lower. Pressurizer water temperature will initially rise.
D.
RCS temperature will initially lower. Pressurizer water temperature will initially lower.
Feedback K/A MATCH ANALYSIS The K/A requires the testing of knowledge of operational implications of a PCS malfunction, which is accomplished with the safety valve leaking. The safety valve has a pressure control function to keep the RCS from encroaching on the RCS pressure safety limit. The K/A also requires testing the implications of expansion of liquids as temperature increases. Therefore, the K/A is met because the RCS temperaure goes up, causing the liquid volume to expand.
The safety valve leaks, reducing the pressure in the pressurizer. Both of these items cause an insurge into the pressurizer, which lowers the pressurizer temperature (operational implication).
ANSWER CHOICE ANALYSIS:
A. Incorrect. Xenon is burning out due to the power ascention, which will cause RCS temperature to increase. The rise in RCS temperature will cause the RCS volume to expand coupled with the Safety Valve leaking causes an above average insurge into the Pzr, which will drop the average water temperature in the Pzr initially beyond the heaters capacity to compensate.
B. Correct. See analysis for A above.
C. Incorrect. See analysis for A above.

A INCORRECT Bus volts on DCB-1-XIT-5901 would have had to have dropped below 110VDC.
B CORRECT Per ARP-001, XCP-636, Annunciator Point 1-5, page 7. Since no other annunciators have actuated this one annunciator alone serves as indication that substitute power sources have come on line.
C INCORRECT This would be correct if annunciator INV 3/4 had actuated.
D INCORRECT This would be correct if annunciator INV 3/4 had actuated AND volttage had dropped to 110 VDC.

A plant trip and loss of all AC has occurred.
The B DIG failed to start automatically and CANNOT be started from the Control Room.
An operator has attempted to start the B D/G locally by manually depressing only one of the manual air start valves for B D/G, but the D/G does NOT start.
Which ONE of the following is a possible cause of the B D/G NOT starting?
A.
Only one main air start valve was overridden.
B.
The Local-Remote switch is in MAINTENANCE.
C, Pressure in the B DIG air receivers is less than 175 psig.
D.
The barring device interlock is failed in the ENGAGED position.
Feedback DISTRACTORS:
A INCORRECT Overiding only one main air start valve is all that is necessary to start the D/G since the two air start valves are in parallel.
B INCORRECT The MAINTENANCE position allows a test start but blocks generator actuation by blocking closure of the D/G breaker. The diesel will start, but will not load electrically.
C CORRECT Factory testing with air receiver pressure less than 225 psig resulted in prolonged diesel start times. 175 psig was selected as it is sufficiently low to be a possible cause of the D/G not starting and the 75 is similar to the 75 in the DG START AIR PRESS LO annunciator setpoint of 275 psig.
D INCORRECT If the diesel must be emergency started manually by using the provided tool to open the main air start valves, the barring device interlock is bypassed and the diesel would have started.

Given the following conditions:
- A loss of offsite power has occurred.
- Both DGs are running at full load.
- Due to problems with the B fuel oil transfer pumps, the B DG day tank is unable to be replenished.
- The DG B OIL DAY TK LVL LO-LO annunciator is received on the MCB.
If the conditions given above remain unchanged, which ONE of the following is true regarding the operation of the EDG?
A.
The crew should unlock and open the fuel oil transfer cross-connect valve to allow the A fuel oil transfer pumps to refill the B DG Day Tank while monitoring the B DG Day Tank level to prevent overfilling the tank.
B.
The crew should make up the ALT FILL connection, then unlock and open the B DG fuel oil transfer pump bypass valve to allow the engine driven fuel oil pump to take a suction directly from the discharge of the DG Fuel Oil Un-loading Pump.
C The crew should allow the B DG to continue to run until it runs out of fuel.
D.
The crew should immediately secure the B DG, the loss of fuel oil is imminent.
Feedback DISTRACTORS:
A INCORRECT The only fuel oil transfer system cross-connect valve is located on the suction side of the transfer pumps.
B INCORRECT The ALT FILL connection does not align to the suction of the engine driven fuel oil pump and the Fuel Oil Un-loading Pump can only discharge directly to either of the Fuel Oil Storage Tanks or back to the Truck Un-load connection.
C CORRECT Per IB-5, the low-low alarm indicates that approximately 30 minutes of full-load running time remains. Since this alarm actuates at a Day Tank level of 235 gallons and the diesel uses 5 pgm at full load (235/5=47), a band of 30 to 45 minutes was used.
D INCORRECT The EDG should not be immediately securred. The EDG should be allowed to run until the fuel is gone.

The crew is performing actions per EOP-1 7.0, Response to High Reactor Building Pressure, following a plant event. While verifying Service Water flow to the RBCUs the crew observes the following:
- Annunciator RBCU 2A DISCH TEMP HI/SMOKE is lit and has been determined that it is NOT due to smoke.
- Flow oscillations are observed on FI-4466, SWBP A DISCH FLOW GPM.
Given the above conditions, which ONE of the following describes the actions the crew should take to correct this situation and why?
A.
The crew should open MVB-3109B, RBCU 2A Outlet Isolation Valve, to increase cooling water flow through RBCU 2A.
B.

D. The crew should shut MVB-3109A, RBCU 1A Outlet Isolation Valve, to increase cooling water flow through RBCU 2A.
Feedback D ISTRACTORS:
A INCORRECT This is the on-service cooler and MVB-3109B is already open.
B INCORRECT This action will take RBCU 2A off service effectively removing SWBP Train B from service.
C CORRECT Per SOP-i 17, page 34, Another special consideration for post accidnet operation is the high temperatures (214°F) of the SW leaving the RBCUs.
This temperature could result in flashing across the orifices in the RBCU discharge line. Flow should be checked to ensure that flow oscillations from flashing do not limit RBCU heat removal. One way to reduce flashing would be to initiate flow through the parallel (idle) RBCU to reduce the bulk temperature at the orifice.
D INCORRECT MVB-3109A should already be shut. Per lB-i Post accident operation only requires the operation of one RBCU per train. The cooler, which will operate, is selected using the RBCU TRAIN A/B/EMERG switches on the MCB. The normally open outlet valves from the non-selected RBCU closes on an SI signal to maximize SW flow through the coils of the running RBCU.
In the event of a Safety Injection, all eight valves receive an 5 signal to opoen: but, the non-selected RBCUs 3109 valves open signal will be overridden and these 3109 valves will remain closed or will close, if open.

A manual-handwheel operated, rising stem gate valve through which fluid is NOT flowing is to be verified OPEN as a part of a Routine System Lineup Verification.
- The valve is located in a cubicle designated as a high radiation area, with the highest exposure reading being 225 mRem/hr, occurring on contact with the bonnet of the valve.
- The cycling of the valve (full open
- full shut
- full open) is known to take 3 minutes in the area.
- The boundary for the high radiation area is located approximately 3 feet from the valve, which is in plain view from the boundary.
Given the above conditions and in accordance with SAP-i 53, Independent Verification, which ONE of the following describes how an Independent Verification should be performed this valve?
A.
The amount of radiation exposure expected to be recieved is sufficient to allow the Shift Supervisor to waive the requirement for independent verification. The valve position may be verified by initiating flow through the valve and observing system process parameters indicating flow through the valve.
B.
The amount of radiation exposure expected to be recieved is sufficient to allow the Shift Supervisor to waive the requirement for independent verification. The valve position may be verified by observing the valves stem position from the boundary of the high radiation area.
C The valve handwheel should be turned in the clockwise direction until movement of the stem is detected and then returned to its full open position.
D.
Since the valve is located in a high radiation area and this is a Routine System Lineup Verification, the Independent Verification need not be performed.

Given the above conditions and in accordance with SAP-153, "Independent Verification," which ONE of the following describes how an Independent Verification should be performed this valve?
A. The amount of radiation exposure expected to be recieved is sufficient to allow the Shift Supervisor to waive the requirement for independent verification. The valve position may be verified by initiating flow through the valve and observing system process parameters indicating flow through the valve.

C!o" The valve handwheel should be turned in the clockwise direction until movement of the stem is detected and then returned to its full open position.
D. Since the valve is located in a high radiation area and this is a Routine System Lineup Verification, the Independent Verification need not be performed.
Feedback DISTRACTORS:
A INCORRECT Greater than 10 mrem would have to be received in order for the Shift Supervisor to waive the requirement for independent verification. Under the conditions given, 11.25 mrem would be received if the valve were to be cycled through its full range of travel. lAW section 6.4.1 of SAP-i 53, Valves to be verified open will be manipulated in the closed direction only as necessary to remove any slack from the operating mechanism and verify valve stem movement. The valve will then be fully opened, subject to normal precautions on backseating valves.
If the operator followed the requirements of SAP-i 53, the time needed to properly verify the valves position would require far less than the time stated to perform a complete cycle of the valve.
B INCORRECT The Shift Supervisor may not waive the requirements (see distractor analysis for A above). The remainder of this distractor is plausible in that it is possible to determine the position of a rising stem valve by visually observing stem position.
C CORRECT The operator would not expect to receive an exposure exceeding 10 mrem, Valves to be verified open will be manipulated in the closed direction only as necessary to remove any slack from the operating mechanism and verify valve stem movement. The valve will then be fully opened, subject to normal precautions on backseating valves.
This operatiorn should take less than 2 minutes to complete resulting in radiation exposure of only 7.5 mRem or less.
D INCORRECT During the performance of routine system lineup verifications, the first individual performing the check is considered to be the independent verifier, and an additional SECOND check need not be performed. (SAP-i 53 Step 6.2.1.)

An onshift Reactor Operator (RO) has the following recent dose history (TEDE):
- Year 2004 = 4020 mrem
- Year to date 2005 = 459 mrem The RO is directed to perform a job on a component (considered a point source) that has a dose rate of 4400 mrem / hour at one foot. The RO will perform all of the work at 18 inches from the component and the work will take 45 minutes to complete.
Which ONE of the following correctly states the highest level of required approval/notification needed prior to beginning work?
A.
The ROs Supervisor and the Manager of Health Physics Services B. The ROs Department Manager and the HP Manager C.
The General Manager, Nuclear Plant Operations D.
The NRC Feedback K/A MATCH ANALYSIS The question tests knowldge of the facility requirements that are related to the IOCFR2O requirements.
ANSWER CHOICE ANALYSIS:
A. Incorrect. The Dept. Manager must sign. This is a higher level than his Supervisor.
Plausible because this would be correct if the applicant does not add the 459 mrem.
B. (1/1 5)2 x (4400 mrem/hr) x (45 minutes) x (1 hr / 60 minutes) = 1467 mrem 1500 mrem + 459 mrem = 1926 mrem. HPP-153, Step 4.1, gives the admin limit as 1000 mrem. HPP-153, Step 3.3.1 and 3.3.2 state that the Manager of HPS must either sign or be notified by phone and approve per telecon. HPP-1 53, Attachment 1, states that the individuals manager (likely the Operations Manager) and the MP Manager must approve for> 1500 mrem, but < 2000 mrem.
C. Incorrect. Plausible because if the applicant does not account for only working 3/4 of an hour (rather than a full hour), then this answer would be correct due to calculating > 2000 mrem.
D. Incorrect. Plausible because NRC notification (vice approval) would be necessary if the 2004 accumulated dose were added to the current year dose.

An onshift Reactor Operator (RO) has the following recent dose history (TEDE):
- Year 2004 = 4020 mrem
- Year to date 2005 = 459 mrem The RO is directed to perform a job on a component (considered a point source) that has a dose rate of 4400 mrem / hour at one foot. The RO will perform all of the work at 18 inches from the component and the work will take 45 minutes to complete.
Which ONE of the following correctly states the highest level of required approval/notification needed prior to beginning work?
A. The RO's Supervisor and the Manager of Health Physics Services B..... The RO's Department Manager and the HP Manager C. The General Manager, Nuclear Plant Operations D. The NRC Feedback KIA MATCH ANALYSIS The question tests knowldge of the facility requirements that are related to the 10CFR20 requirements.
ANSWER CHOICE ANALYSIS:
A. Incorrect. The Dept. Manager must sign. This is a higher level than his Supervisor.
Plausible because this would be correct if the applicant does not add the 459 mrem.
B. (1/1.5)2 x (4400 mrem/hr) x (45 minutes) x (1 hr / 60 minutes) = 1467 mrem 1500 mrem + 459 mrem = 1926 mrem. HPP-153, Step 4.1, gives the admin limit as 1000 mrem. HPP-153, Step 3.3.1 and 3.3.2 state that the Manager of HPS must either sign or be notified by phone and approve per telecon. HPP-153, Attachment 1, states that the individual's manager (likely the Operations Manager) and the MP Manager must approve for> 1500 mrem, but < 2000 mrem.
C. Incorrect. Plausible because if the applicant does not account for only working 3/4 of an hour (rather than a full hour), then this answer would be correct due to calculating> 2000 mrem.
D. Incorrect. Plausible because NRC notification (vice approval) would be necessary if the 2004 accumulated dose were added to the current year dose.

While responding to a plant event with RCS pressure at 300 psig, the crew received a YELLOW condition on the Status Tree for Core Cooling and transitioned to EOP-14.2, Response to Saturated Core Cooling.
Which ONE of the following correctly describes the basis for making this transition?
A.
It will enable the crew to maintain minimum RCS subcooling by verifying RHR is in the cooldown mode.
B. It will enable the crew to maintain minimum RCS subcooling by verifying/establishing SI flow.
C.
It will enable the crew to prevent further degradation of core cooling by starting a RCP.
D.
It will enable the crew to prevent further degradation of core cooling by establishing a vent path.
Feedback DISTRACTORS:
A INCORRECT The first step in EOP-14.2 is to verify that the RHR system has NOT been placed in service in the cooldown mode. The stem includes a mention of RCS pressure being> 250 psig to preclude this as a possible answer since Step 2 of EOP-14.2 states that if RCS pressure is < 250 psig, verify RHR flow..
B CORRECT This is the purpose as stated in the bases and Lesson Plan. Verifying SI flow is the second step in EOP-14.2.
C INCORRECT While this is the bases, EOP-14.2 does not direct starting RCPs even though having no running RCPs is one of the plant conditions that would result in receiving the Yellow path as mentioned in the stem.
D INCORRECT While this is the bases, all potential vent paths are checked closed to terminate loss of RCS inventory.
