A. immediately Steam Dumps B'!' immediately Atmospheric Reliefs C. only after verifying adequate shutdown margin Steam Dumps D. only after verifying adequate shutdown margin Atmospheric Reliefs Wednesday, January 14, 20151:11:42 PM 2
QUESTIONS REPORT for 1503 RO Exam DIS TRACTOR ANALYSIS:
A. Incorrect, Plausible since the first part is correct the coo/down is commenced when the step in the procedure is reached. Also plausible since the guidance in the procedure is to use Steam Dumps to coo/down, however if the candidate does not recognize that the MS/Vs would be closed due to Phase B, the Steam Dumps are not available, thus Atmospheric Reliefs must be used.
B. Correct, With CNMT pressure> 2.8 psig (phase BJ the MS/Vs are closed, thus the Atmospheric Reliefs would have to be used. Also for ES-1.2 the coo/down to Cold Shutdown is commenced when the step in the procedure is reached. Adequate shutdown margin will be obtained with borated water from SJ flow.
C. Incorrect, Plausible since other emergency procedures require that adequate shutdown margin for cold shutdown be established before cool down can be commenced when plant conditions have stabilized (such as ES-0.2). Also plausible since the guidance in the procedure is to use Steam Dumps to coo/down, however if the candidate does not recognize that the MS/Vs would be closed due to Phase B, the Steam Dumps are not available, thus Atmospheric Reliefs must be used.

- 3. 011 EK3.15003 Given the following plant conditions:
Unit 2 has experienced a large break LOCA Conditions are met for entry into ES-1.3, "Transfer to RHR Containment Sump."
Which ONE of the following completes the statements below?
Containment sump level must be (1) to initiate auto sump swap over to ensure (2)
A'! (1) > 11 %
(2) containment sump level is high enough to provide adequate suction head for the RHR pumps.
B. (1) >11%
(2) sufficient RWST water has been sprayed into the containment atmosphere to limit post accident Iodine concentration.
C. (1) > 18%
(2) containment sump level is high enough to provide adequate suction head for the RHR pumps.
D. (1) > 18%
(2) sufficient RWST water has been sprayed into the containment atmosphere to limit post accident Iodine concentration.
Wednesday, January 14, 20151:17:18 PM 3
QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. Correct, In accordance with FSAR chapt 6, when the RWST low level (27%) is received enough water has been injected into the RCS and thus into Containment to ensure that sufficient water level (> 11 %) exists. This will allow for sump swapover and ensure RHR pump suction head requirements are met after swapover is completed.
B. Incorrect, Plausible since the first part is correct. Also plausible since limiting Iodine in the containment atmosphere is a function of containment spray, however containment spray is for limiting Peak CNMT pressure during the first stages of a LOCA. CNMT spray after the sump swapover when sufficient ice has melted and added sodium tetra-borate will then provide for Iodine retention.
C. Incorrect, Plausible if the candidate gets the minimum level in CNMT for CNMT spray pump suction confused with the auto swapover value. In accordane with ES-1.3, after verifying that CNMT sump level is> 18% then the operators manually align CNMT spray pumps to take a suction on the CNMT SUMP. Also plausible since the second part is correct.
- 0. Incorrect, Plausible if the candidate gets the minimum level in CNMT for CNMT spray pump suction confused with the auto swapover value. In accordane with ES-1. 3, after verifying that CNMT sump level is > 18% then the operators manually align CNMT spray pumps to take a suction on the CNMT SUMP. Also plausible since limiting Iodine in the containment atmosphere is a function of containment spray, however containment spray is for limiting Peak CNMT pressure during the first stages of a LOCA. CNMT spray after the sump swapover when sufficient ice has melted and added sodium tetra-borate will then provide for Iodine retention.

- 4. 022 AA2.04 004 Given the following plant conditions:
- Unit 1 was operating at 100% power when FCV-62-93, Charging Flow Control, malfunctioned to limit total charging flow to 65 gpm.
- The plant is at normal operating temperature, pressure and level
- Normal letdown is in service on a 75 gpm orifice
- Identified leakage is 10 gpm
- Unidentified leakage is .01 gpm
- RCP seal leak-off is 3 gpm per pump If NO operator actions are taken, approximately how much time will elapse before the following alarm is received:
"LS-68-335E/D PRZR LVL LOW HEATER OFF & LETDOWN SECURED" (Assume PZR is 62 gal/%)
A. 63 minutes B~ 83 minutes C. 116 minutes D. 133 minutes DIS TRACTOR ANALYSIS:
A. Incorrect, Plausible if candidate misreads the charging flow and uses 55 gpm based on the minimum value of charging if flow controller fails to minimum.
Thus 63 minutes Total flow out of RCS= 20 + 10 + 12 + 0 = 42 gpm : 63 minutes B. Correct, PZR level @ 100% power = 60% : Letdown isolates @ 17% : 60 - 17 =43% x 62 gal/% = 2666 gallons.
Delta charging & letdown= 10 gpm: Identified leakage= 10 gpm : Unidentified leakage =.01 gpm (negligible) : RCP seal leakoff =4x3= 12 gpm into VCT.
Total flow out of RCS= 10 + 10 + 12 + 0 =32 gpm : 83 gpm C. Incorrect, if the candidate uses 3 gpm as RCP seal leak off vs 12 gpm total Total flow out of RCS= 10 + 10 + 3 + 0 =23 gpm = 115.9 D. Incorrect, Plausible if candidate does not use seal leakoff flow as leakage Total flow out of RCS= 10 + 10 + 0 + 0 = 20 gpm + 133 minutes Wednesday, January 14, 20151:25:07 PM 4

- 5. 025 AG2.1.28 005 Given the following plant conditions:
- Unit 1 RCS is in Midloop condition
- B Train RHR is in service
- Eight S/G Nozzle Dams are installed
- Subsequently, Nonessential Control Air Header depressurizes to 0 psig Which ONE of the following identifies the impact on the plant?
A. RHR flow will lower resulting a loss of RHR shutdown cooling.
B. eves charging will rise resulting in RCS overfill and overflow out the SIG manways.
C. CVCS charging flow will lower and will result in reduced RCS level and possible RHR pump cavitation.
IY. RHR flow will rise but will be limited by valve restraints preventing RHR suction vortexing and loss of shutdown cooling.
D/STRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate thinks that the affected RHR Hx flow control valve would fail closed on a loss of control air - since they fail open, loss of flow is not possible based on this error mode.
B. Incorrect, Plausible however charging flow will increase due to the failure of 62-89 and 62-93 open, the nozzle dams should prevent overflow out the manways since RCS is required to have a vent path when nozzle dams are installed. The pressure head with the PZR PORV vent path is insufficient to blow-out the nozzle dams.
C. Incorrect, Plausible if the candidate gets confused about the direction of failure of FCV-62-93 and thinks it will fail closed vs open.
D. Correct, O-G0-13 Appx S directs the installation of a blocking device on FCV-74-16 and 74-28. The device is intended to prevent the RHR Hx flow control valves from failing full open upon a loss of control air. The full open position (without the blocking device) of these valves may increase RHR flowrate and cause cavitation during midloop level operation. (Reinforced by AOPs M.02 & R.03).

QUESTIONS REPORT for 1503 RO Exam DIS TRACTOR ANALYSIS:
A. Incorrect, Plausible since the the first part is correct, at 2205 psig all PZR heaters will be energized. However with the Master controller in Manual, the spray valves will not automatically open. Candidate may select this answer if they do not recognize that the spray valves are being controlled in manual and will not respond to high pressure signal.
B. Incorrect, Plausible if the candidate does not recognize that all heaters will remain on since the master pressure controller was placed in manual after all heaters were energized. Also the spray valves are being controlled in manual and will not respond to high pressure signal.
C. Correct, With Pressurizer pressure dropping to 2205 psig, all PZR heater banks will be energized in an attempt to return RCS pressure to its normal value. Also with the master pressure controller in Manual, the spray valves will not function to control pressure, however PORV 68-334 is not controlled by master controller output. PORV will open at setpoint to control pressure.
PORV 68-340 is controlled by master controller in manual and will not open to control pressure. Student may confuse PORVs.
D. Incorrect, Plausible since the second part is correct, the PZR pressure will be controlled by PORV 68-334 when the master pressure controller is in Manual.
However if the candidate does not recognize that all heaters will remain on since the master pressure controller was placed in manual after all heaters were energized, then the candidate may select this answer.

- 7. 029 EK2.06 007 Given the following plant conditions:
Unit 1 at 100% power
- A transient occurs that requires a manual reactor trip.
The OATC attempts to trip the reactor but the reactor fails to trip.
Which ONE of the following completes the statement below relative to the failure of the reactor trip breakers that would have caused the reactor NOT to trip and the local action(s) required to trip the reactor?
The Reactor Trip Breaker's 125V de shunt trip coils failed to (1) and to trip the reactor locally (2) Reactor Trip Breaker(s) must be open.
ill m A'! energize only one B. energize both C. de-energize only one D. de-energize both Wednesday, January 14, 2015 2:22:17 PM 7
QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Correct, the shunt trip coils should be energized from the reactor trip hand switches (and from the SSPS for the reactor trip breaker) and if this did not occur then one of the two breaker trip devices would not function, thus contributing to the A TWS along with whatever caused the UV coil on the breakers to also fail to trip the breakers. Opening either one of the breakers would cause the reactor to trip.
B. Incorrect, The failure to energize the reactor trip breaker shunt coils contributing to the reactor failing to trip is correct but both breakers do not have to be open to cause a reactor trip, only one has to be opened. Plausible because the failure to energize the shunt coils is correct and the breakers scheme could be mistaken to be in parallel instead of series because there is a bypass breaker in parallel with each reactor trip breaker C. Incorrect, The the reactor trip switch actuation (and SSPS signal for RTB) energizes the shunt trip coils to cause a trip, so the failure would be to energize not failure to de-energize and the reactor would trip when either breaker was opened.
Plausible because the failure to deenergize the coils would be correct concerning the undervoltage coils and the reactor tripping after either of the breakers opening is correct.
D. Incorrect, The the reactor trip switch actuation (and SSPS signal for RTB) energizes the shunt trip coils to cause a trip, so the failure would be to energize not failure to de-energize and the reactor trip would not required both breakers to be open. It would trip when either breaker was opened. Plausible because the failure to deenergize the coils would be correct concerning the undervoltage coils and the breakers scheme could be mistaken to be in parallel instead of series because there is a bypass breaker in parallel with each reactor trip breaker Wednesday, January 14, 2015 2:22:17 PM 8

QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Correct, With the "B" MFPT tripped and its trip bus energized, when the "A" MFPT trips it causes the TDAFW pump to immediately start. Also the cooling water supply to the lube oil system for the TDAFW pump comes from one of the stages on the discharge and is sent back to the suction of the pump. This flow is only provided when the TDAFW pump is running.
B. Incorrect, Plausible since the TDAFW pump would get a start signal from SG level following a plant trip and would be the only start signal present if the "B" MFPT was not already in a tripped condition with its trip bus energized. Also plausible since ERCW is the normal source of cooling water to safeguards equipment.

Given the following plant conditions:
Unit 2 is at 100% power.
- A Loss of Off-Site power occurs.
- A blown fuse has caused the normal Loop 2 MSIV valve position light indication on the handswitch to be lost.
Assuming NO operator action, which ONE of the following completes the statement below?
The Loop 2 MSIV will (1) and the position of the Loop 2 MSIV (2) be determined from the MONITOR LIGHTS 2-XX-55-6L panel.
A. (1) remain open indefinitely (2) can B. (1) remain open indefinitely (2) can NOT C'!" (1) eventually fail closed (2) can D. (1) eventually fail closed (2) can NOT Wednesday, January 14, 2015 2:57:06 PM 11
QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Incorrect, Plausible since the MS/Vs are held open by air pressure and they are provided with accumulators, however they will stay open only for a short period of time following a loss of offsite power due to a loss of control air pressure. Also plausible since the second part is correct.
B. Incorrect, Plausible since the MS/Vs are held open by air pressure and they are provided with accumulators, however they will stay open for a only short period of time following a loss of offsite power due to a loss of control air pressure. Also plausible if the candidate does not recall that the MSIV postions are displayed on the status monitoring panel in the control room.
C. Correct, The MS/Vs are provided air from normal station control air and will go closed after some period of time without control air which is lost during a Loss of Offsite power. SG 2 Main Steam Line Isolation valve position is displayed not only on the handswitch in the main control room but also on 2-XX-55-6L monitoring panel. Power supply to the PAM indications is different than the power supplied to the handswitch indications.
D. Incorrect, Plausible since the first part is correct. Also plausible if the candidate does not recall that the MSIV positions are displayed on the status monitoring panel in the control room.

QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. Incorrect, Plausible, since a loss of VIPB 2-111 does effect the Loop 1 spray valve, however it results in isolation of A train essential air, not but does not cause the Loop 1 spray valve to open. This would make Loop 1 spray valve unavailable for pressure control. Also plausible since a loss of VIPB-111 does result in a loss of valve indication for Loop 2 spray valve, however loop 2 spray valve is available for pressure control. Loop 2 spray valve is supplied by Train B essential air.
B. Incorrect, Plausible, since a loss of VIPB 2-111 does effect the Loop 1 spray valve, however it results in isolation of A train essential air, not but does not cause the Loop 1 spray valve to open. This would make Loop 1 spray valve unavailable for pressure control. Also plausible if the candidate thinks that the valve goes open and given a loss of RCS pressure control, a reactor trip would be logical.
C. Incorrect, Plausible since the first part is correct. Also plausible to think that if the suction valve went open to close the valve. However the direction in AOP-P.04 is for the operators to trip the reactor since the suction valve could not be closed from the MGR.
D. Correct, In accordance with AOP-P.04, if VIPB 2-111 loses power the interposing relays associated with the RWST suction valves for the CCP for train A causes the RWST valve to open. This will cause a rapid boration of the RCS, thus the operators are directed to trip the reactor.

125V DC VITAL BAT BD II ABNORMAL (1-M-1C, B-5)
FS-3-48B STM GEN LOOP 2 STEAMIFEEDWATER FLOW MISMATCH (1-M6-B, B7)
Loop 2 SIG level is 40% and lowering Loop 1, 3 and 4 SIG levels are stable and on program.
Loop 2 SIG FW inlet flow indicators are reading down scale LOW.
All other 125V DC Vital Board II indications and alarms are NORMAL.
Which ONE of the following identifies the required immediate action(s), to be taken in accordance with AOP-S.01, "Loss of Normal Feedwater?"
Take manual control of - - -
A~ Loop #2 Main Feed Reg valve, attempt to control SG level. Manual Rx Trip will be required B.

MFPT 1A & 1B Master Speed controller, raise its output and restore Loop #2 SIG level Wednesday, January 14, 2015 3:15:08 PM 13
QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANAL YS/S:
A. Correct, If fuse KED25 blows, the VBB abnormal alarm will be in alarm. Also if this fuse blows, the Loop #2 MFRV will fail closed. Per AOP-S.01, the RO will be directed to attempt to control the Main or Bypass FRV to return level to program.
Manual control of the MFRV will not work due to the FRV being failed closed. Thus a reactor trip will be required per the immediate actions due to SGWL trip being imminent.
B. Incorrect, Plausible since direction to control SG loop #2 using the bypass is part of AOP-S.01, however at 39% power SIG level will continue to rapidly lower which would require a reactor trip due to an imminent reactor trip on low SIG water level.
C. Incorrect, Plausible since there is guidance in AOP-S.01 to take manual control of a MFP speed control if the candidate thinks that the alarms are caused by a loss of MFP speed control. Also a loss of automatic speed control would cause feedflow to lower and generate a Low Feedflow alarm. However the alarms are indicative of a failed feed reg valve not a failure of MFPT speed control.
D. Incorrect, Plausible because a loss of MFPT speed control would require taking manual control of the MFP (Master or Individual controller). A loss of MFP speed control could result in low FW inlet flow and lowering SG water levels. However the FRV is failed closed and this action would not restore level.

Unit-1 is operating at 80% power.
Due to grid disturbances the crew had entered AOP-P.07, "Degraded Grid Conditions or Generator Voltage Regulator Malfunction."
Grid frequency has held steady at 59 Hz for twenty minutes.
The Unit Supervisor directs the OATC to trip the reactor.
In accordance with AOP-P.07, "Degraded Grid Conditions or Generator Voltage Regulator Malfunction," which ONE of the following identifies the reason for this required action?
A. The Tech Spec limit for frequency on a DIG has been exceeded.
B~ To prevent exceeding 25% of lifetime limit of off-frequency operation of LP turbine.
C. The auto reactor trip setpoint has been exceeded.
D. To prevent exceeding improper bearing loading and turbine misalignment.
D/S TRACTOR ANAL YS/S:
A. Incorrect, Plausible since there is a Tech Spec low frequency limit, and the candidate could choose this reason, however the setpoint is < 58. 8 Hz not 59 Hz which is given in the stem.
B. Correct, In accordance with AOP-P.07, Appendix B, if freguency is< 59.5 Hz for more than 15 minutes a manual Rx trip is directed as an Administrative limit to prevent exceeding more than 25% of lifetime limit for off-frequency operation of the LP turbine.
C. Incorrect, Plausible there are low grid frequency trip values and the candidate could get the values confused. The low frequency trip is 57 Hz not 59 Hz.
- 0. Incorrect, Plausible since there is direction in O-G0-4, to limit the bearing loading and misalignment which would raise turbine vibration, however this limit is for temperature difference between condensers not low grid frequency.

QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Correct, The mitigating strategy used in ECA-1.2 is to attempt to isolate the leak by isolating RHR cold leg injection one at time. Also in accordance with ECA-1.2, the operators are directed to monitor RCS pressure as an indicator that the LOCA has been isolated.
B. Incorrect, Plausible since the first part is correct. Also plausible since the normal method determining if an RCS leak has been isolated is to monitor PZR (such as AOP-R.05)
C. Incorrect, Plausible if the candidate thinks that since SI pumps are located in the Aux Bldg that the strategy of isolating the SI pumps would be used to identify and isolate the leak, however RHR is more likely since it is a lowpressure system which could be subject to high pressure and possible failure. Also plausible since the second part is correct.
D. Incorrect, Plausible if the candidate thinks that since SI pumps are located in the Aux Bldg that the strategy of isolating the SI pumps would be used to identify and isolate the leak, however RHR is more likely since it is a lowpressure system which could be subject to high pressure and possible failure.

FR-H.1, "Loss Of Secondary Heat Sink", is in progress.
RCS feed and bleed had been initiated.
Auxiliary Feedwater (AFW) capability was restored.
All Steam generators (SGs) indicate 8% Wide Range level and 90 psig.
Core exit TCs are stable at 552°F.
Which ONE of the following identifies an acceptable method of re-establishing feed flow under these conditions and the reason why?
A. Feed ONLY one SG at a rate of 50 to 100 gpm to prevent MSIV closure due to negative rate signal.
B~ Feed ONLY one SG at a rate of 50 to 100 gpm to minimize thermal stresses to the SG components.
C. Feed ALL SGs at maximum rate to ensure the minimum AFW flow required for heat sink is established to allow termination of bleed and feed.
D. Feed ALL SGs at maximum rate to establish minimum steam generator level requirements to allow termination of RCS bleed and feed.
D/STRACTOR ANALYSIS:
A. Incorrect, Plausible because only one steam generator should be fed and the feed rate is within the 50-100 gpm range and the MS/V's do have a negative rate isolation signal.
- 8. Correct, One SG is fed at a rate of 50-100 gpm to minimize thermal shock and potential damage to the SG tubesheet when SGs are hot and dry. After feeding a minimal rate, flow may be raised when wide range level exceeds 10%.
C. Incorrect, Plausible because the level is below the requirement for heat sink and establishing maximum flow to all steam generators would provide a flow rate above the minimum for heat sink. However, having heat sink flow established does not allow the termination of bleed and feed. The steam generator level requirement must be met to terminate.
D. Incorrect, Plausible with bleed and feed established, it is desirable to establish the required steam generator level that permits termination of bleed and feed as quickly as possible and because if the core exit temperatures had been rising a maximum flow rate would have been established to a steam generator.

QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. Correct, Between times 0900 - 1030 (90 Min) Using ECA-1.1, curve 9, the value is approximately 325 gpm. The Basis states "the operator is then instructed to establish the minimum EGGS flow needed to match decay heat in order to further decrease EGGS pump Flow and delay RWST depletion. This value of 325 gpm is in the acceptable region using the graph from time of trip AND meets the requirement of Minimum Flow to delay RWST depletion. The procedure states EGGS pumps may be started and stopped as necessary to accomplish the desired flow rate.
B. Incorrect, Plausible since the first part is correct, however the action is not correct.
Also plausible if student does not know procedure requirement to start or stop pumps as neccessary due to a LOCA. The student may think that due to a LOCA pumps must not be stopped.
C. Incorrect, Plausible due to 400 gpm meets the curve requirement however it does not meet the intent of the step which is to meet the minimum flow requirements while still meeting the curve requirements. Second part is correct in EGGS pumps may be started and stopped as necessary to accomplish the desired flow rate.
D. Incorrect, Plausible due to 400 gpm meeting the curve requirement however it does not meet the intent of the step which is to meet the minimum flow requirements while still meeting the curve requirements. Plausible if student does not know procedure requirement to start or stop pumps as neccessary due to a LOCA. The student may think that due to a LOCA pumps must not be stopped.

B. Allow the RCS to heat up to prevent a PTS condition.
C~ Raise MDAFW flow to maintain RCS T-hots stable.
D. Initiate TDAFW pump flow to maintain RCS T-hots stable.
D/S TRACTOR ANALYSIS:
A. Incorrect, Plausible since normally a tranisition to FR-H. 1 would be made, however a Note prior to step 2 directs that if the feed flow capability of 440 gpm or greater is available then a transition to FR-H. 1 is not required.
B. Incorrect, Plausible since FR-P.2 will check for RCS temp stable or rising as a condition to exit the procedure, however step 2 of ECA-2. 1 requires the operators to stabilize RCS That not let the temperature rise.
C. Correct, In accordance with Step 2 of ECA-2. 1 the operators are to stabilize RCS That by raising feed flow or dumping steam. Both MDAFW pumps are available to provide feed flow. With That rising the direction of Step 2. d requires controlling T-hot by raising feed flow or dumping steam.
D. . Incorrect, Plausible since if the candidate did not recognize that MDAFW was available then TDAFW would be used to control feed flow. However in a prior step of ECA-2. 1 the steam supply valves for the TDAFW pump are closed thus the MDAFW pumps would remain available if needed for feed flow.

B. Verify that the reactor protection system and rod control blocks function as designed.
C. Place rod control in MANUAL and immediately insert control bank D to 216 steps.
D. Manually trip the reactor and go to E-0, "Reactor Trip or Safety Injection".
D/STRACTOR ANALYSIS:
A. Correct, In accordance with AOP-C.01, the operators are to attempt to stop uncontrolled rod motion by placing the rod control selector switch in the Manual position and then verify that rod motion stops.
B. Incorrect, Plausible since the controls are supposed to stop moving out based on the interlock to block bank 0 withdrawal, it would be logical to just observe that the interlock did stop rod motion. However that is not the direction given in the procedure and is not in keeping with conservative decision making associated with reactivity control.
C. Incorrect, Plausible since this guidance is provided in AOP-C.01 to return the plant to its original stable condition, however its not the first thing that the operators would do to stabilize the plant.
- 0. Incorrect, Plausible if the candidate thinks that there is an uncontrolled reactivity event in progress and need to terminate power production to maintain the plant in a safe condition. Also this is the guidance given in AOP-C.01 if after taking manual control of the rods the rod motion does not stop. However this in not the first action required to be taken.

A. (1) is (2) automatic Safety Injection actuation B. (1) is (2) drawing a bubble in the reactor vessel head C. (1) is NOT (2) automatic Safety Injection actuation
[Y. (1) is NOT (2) drawing a bubble in the reactor vessel head Wednesday, January 14, 2015 3:54:34 PM 20
QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate does not recognize that the RCS is at or near saturated conditions for the reactor vessel upper head and voiding is occurring.
Also plausible since the RCS is below the automatic actuation setpoint for Safety Injection and if they did not recognize that Auto SI has been procedurally blocked prior to the depressurization step in ES-0. 2.
B. Incorrect, Plausible if the candidate does not recognize that the RCS is at or near saturated conditions for the reactor vessel upper head and voiding is occurring.
Also plausible since, the second part is correct.
C. Incorrect, Plausible since the first part is correct. Also plausible since the RCS is below the automatic actuation setpoint for Safety Injection and if they did not recognize that Auto SI has been procedurally blocked prior to the depressurization step in ES-0. 2.
D. Correct, With RCS pressure rapidly dropping to near saturation and an associated rapid increase in PZR level would indicate that RCS voiding is occurring which would rapidly force water into the PZR, thus PZR level would not be an accurate indication of total RCS inventory.

QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. Incorrect, Plausible because a manual turbine trip is required if load is < 30% and vacuum > 1. 72 psia, however the Main Turbine will not automatically trip until condenser pressure is between 3. 9 and 5.4 psia. Also plausible since, in most other procedures, the operators are directed to control Tave= Tref However, in accordance with AOP-S.06, the operators are to allow the controls to lower in automatic until reactor power is < 20%, then take manual control and maintain power at 15%.
B. Correct, In accordance with AOP-S.02, if Turbine load is< 30% and condenser vacuum is > 1. 72 psia, *a manual turbine trip is required but the Main Turbine will not automatically trip until condenser pressure reaches between 3.9 to 5.4 psia.
Also in accordance with AOP- S.06, the operators are to take manual control of the rods once power is less than 20% and stablize reactor power 15%.
C. Incorrect, Plausible if the candidate thinks that an automatic turbine trip would occur on low condenser vacuum. Also plausible since, in most other procedures, the operators are directed to control Tave= Tref However, in accordance with AOP-S.06, the operators are to allow the controls to lower in automatic until reactor power is < 20%, then take manual control and maintain power at 15%.
D. Incorrect, Plausible if the candidate thinks that an automatic turbine trip would occur on low condenser vacuum. Also plausible since, in accordance with AOP-S.06, the second part is correct. The operators are to maintain reactor power 15%.

- 25. W/E08 EKl.2 025 Given the following plant conditions:
Unit 1 reactor tripped from 100% power due to a LOCA.
The crew is performing the actions of FR-P.1, "Pressurized Thermal Shock."
Conditions can NOT be established to terminate SI flow.
RCS subcooling is 50°F and stable.
Which ONE of the following identifies the basis for starting a RCP at this time?
Starting a RCP will .....
A~ reduce the thermal stress on the Rx vessel.
B. eliminate the need to perform a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> soak of the RCS.
C. reduce the minimum required subcooling to terminate SI.
D. prevent Rx vessel head voiding as RCS pressure is reduced.
DISTRACTOR ANALYSIS:
A. Correct, Starting an RCP results in mixing the warmer water flow from the RCP with the colder EGGS flow, creating a warmer combined flow entering the beltline region of the reactor vessel downcomer which can reduce the stress on the vessel.
B. Incorrect, Plausible if the candidate thinks that by starting an RCP that the mixing will cause the need to soak the RCS temperature for an hour to be not required since flow mixing is occurring, however when in FR-P.1, if a Tcold temperature has decreased greater than 100 °F in less than 60 minutes then a soak is required.
(regardless of whether a RCP is running or not)
C. Incorrect, Plausible since subcooling is considered when performing FR-P.1, but the higher subcooling number is to determine if SI should be terminated (>90°F subcooling) vs 40°F required to start a RCP. Also plausible since minimizing subcooling when starting a RCP is correct for other procedures.
D. Incorrect, Plausible since having an RCP running it would be less likely to potentially draw a bubble in the Rx vessel head, but it is not assured.

B. Incorrect, Plausible if candidate thinks that failure will cause charging flow control valve to go to minimum. If that occurred then PZR level would decrease to 17%.
C. Correct, VCT level will continue to drop, since a failure of LT-62-130 will prevent Auto makeup and auto swapover to RWST. Operators must take manual control of Divert valve and select to VCT position.
D. Incorrect, Plausible if candidate thinks that Auto makeup will occur and maintain VCT level above swap-over value. Auto makeup is not available for this condition.

- 31. Given the following plant conditions:
- Unit 1 is in Mode 4 on RHR with a cooldown to Mode 5 in progress.
- Both trains of RHR are in service.
- The flow is 2500 gpm per train.
- RCS cooldown rate is 25°F/hr.
- The OAC turns the dial for 1-HIC-74-32A, RHR Hx Bypass Flow Controller, from 20% to 40%.
Assuming NO other operator action is taken, which ONE of the following identifies the effect on RCS cooldown rate and on total indicated RHR system flow?
RCS Cooldown Rate Indicated RHR Flow A. Rises Remains Constant BY' Rises Lowers C. Lowers Remains Constant D. Lowers Lowers Wednesday, January 14, 2015 4:58:28 PM 31
QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Incorrect, Plausible since the first part is correct, less bypass flow will cause coo/down rate to increase. Also plausible if the candidate thinks that total system flow will remain constant when the bypass is closed down, since other systems are controlled with that scheme (total system flow remains constant as Hx are bypassed or placed in service). However the outlet valves are manually adjusted and unless manually repositioned, system flow would go down.
B. Correct, The Hx bypass valve is an air operated valve which requires air pressure to close the valve, thus increasing the demand on the controller will cause more air to the valve which causes the bypass valve to close down. This will cause less flow to bypass the Hx, thus coo/down rate will increase. Also since the Hx valves are manually positioned and the sensing line is downstream of where the bypass and Hx outlet come together, by closing the bypass valve less system flow will be seen so indicated flow will decrease.
C. Incorrect, Plausible if the candidate thinks that by changing the controller position from 20% to 40% causes the Hx bypass valve to go open, this would cause more bypass flow and less coo/down. Also if they think the bypass opens then more system flow would be indicated.
D. Incorrect, Plausible if the candidate thinks that by changing the controller position from 20% to 40% causes the Hx bypass valve to go open, this would cause more bypass flow and less coo/down. Also plausible if the candidate thinks that total system flow will remain constant when the bypass is openned, since other systems are controlled with that scheme (total system flow remains constant as Hx are bypassed or placed in service). However the outlet valves are manually adjusted and unless manually repositioned, system flow would go down.

ill A. 2A-A 5 secs B~ 2A-A 10 secs C. 2B-B 5 secs
- 0. 2B-B 10 secs DISTRACTOR ANALYSIS:
A. Incorrect, Plausible since the first part is correct. Also plausible since 5 secs is a start time for an EGGS pump, however SI pumps start at 5 secs and RHR pumps start at 10 secs.
B. Correct, The 2B 6. 9Kv Unit board is the normal power supply to the 2A-A Shutdown Board, thus 2A-A RHR would Jose power. Also the RHR pump wm restart after a 1O sec time delay when power is restored to the SDBD.
C. Incorrect, Plausible if the candidate thinks that the 2B 6.9Kv Unit board is the normal power supply to the 2B-B Shutdown Board, thus they would think that 2B-B RHR would lose power. Also plausible since 5 secs is a start time for an EGGS pump, however SJ pumps start at 5 secs and RHR pumps start at 10 secs.
D. Incorrect, Plausible if the candidate thinks that the 2B 6. 9Kv Unit board is the normal power supply to the 2B-B Shutdown Board, thus they would think that 2B-B RHR would Jose power. Also plausible since the second part is correct.

Pressure Tank A. 550 psig RCDT B. 550 psig PRT C. 600 psig RCDT
[Y. 600 psig PRT D/STRACTOR ANALYSIS:
A. Incorrect, Plausible because 550 psig is the maximum RHR pump discharge pressure allowed to be maintained in accordance with the System Operating Instruction when RHR system is in service and the RCDT is an RCS tank inside containment (like the PRT) which does receive flow and leakoffs from RCS related components.
B. Incorrect, Plausible because 550 psig is the maximum RHR pump discharge pressure allowed to be maintained in accordance with the System Operating Instruction when RHR system is in service and the PRT being the tank that receives flow passing through the valve is correct.
C. Incorrect, Plausible because 600 psig is the pressure that the valve starts relieving and the RCDT is an RCS tank inside containment (like the PRT) which does receive flow and leakoffs from RCS related components.
D. Correct, the RHR discharge relief valve,63-637, starts relieving at 600 psig and is routed to the PRT.

Both Units are at 100% power.
SFP temperature has risen 4°F over the last 2 shifts.
2600 gpm SFPC flow, and 2300 gpm CCS flow Which ONE of the following completes the statement below?
To stabilize SFP temperatures, the crew will raise (1) flow to SFP HX A, and the flow will be limited to NO more than (2)
_{j_L ___@_
A~ ccs 3300 gpm B. ccs 3500 gpm C. SFPC 3300 gpm D. SFPC 3500 gpm DISTRACTOR ANALYSIS:
A. Correct, In accordance with O-S0-78-1 SFPC system, the upper limit of flow for the SFPC system is 2600 gpm, thus to increase the cooling of the SFP the CCS system flow will need to be adjusted. Also Limitation B, indicates that the CCS flow is limited to no more than 3300 gpm to avoid potential HX tube vibration.
B. Incorrect, Plausible since the first part is correct. Also plausible if the candidate gets the CCS system flow confused with the CCS pump flow which should be maintained_::: 3500 gpm, vs the SFP HX flow rate.
C. Incorrect, Plausible since there are steps in the procedure for throttling SFPC flow and the candidate may think that SFPC system flow could be adjusted to increase the cooling of the SF Pit, however the SFPC system flow rate is already at the maximum allowed by procedure. Also plausible since the flow rate value in the second part is correct.
- 0. Incorrect, Plausible that the candidate may think that SFPC system flow could be adjusted to increase the cooling of the SFP, however the SFPC system flow rate is already at the maximum allowed by procedure. Also plausible if the candidate gets the maximum flow confused with the CCS system flow rate.

MIG is performing the Monthly Functional Test of Train 'A' SSPS.
BYA (Train A bypass breaker) is racked in and closed.
RTA (Train A reactor trip breaker) is racked in and closed.
RTB (Train B reactor trip breaker) is racked in and closed.
Subsequently, One 48 Vdc power supply to Unit 1 'B' train SSPS fails.
Which ONE of the following identifies the effect this failure will have on the breakers?
A'!' RTA, RTB, and BYA Open B. RTA, RTB and BYA all remain Closed C. RTA and BYA Open; RTB remains Closed D. RTA and BYA remain Closed; RTB Opens DIS TRACTOR ANALYSIS:
A. Correct, Racking in and closing BYA generates a Train A general warning. The Joss of 48Vdc power supply will result in a Train B general warning. A general warning occurring on both trains of SSPS simutaneous/y will cause an automatic reactor trip signal to be generated in both trains of SSPS. RTB and BYA will receive a trip signal from Train B SSPS. RTA will receive a trip signal from Train A SSPS. Train B SSPS will still function with the loss of one of the two redundant 48Vdc power supplies in the logic cabinet.
B. Incorrect, Plausible if the candidate not realize that the loss of 48Vdc power supply will cause a B train General Warning, thus a reactor trip signal will be sent to both trains of SSPS. With an A train General Warning already present due to racking in and closing BYA, this failure will generate a reactor trip on both trains of SSPS.
C. Incorrect, Plausible since a General Warning exists in A train of SSPS the candidate may think that the General Warning for the Joss of 48Vdc power supply will only effect Train A since 2 general warnings now exist and the logic will be made to cause a trip. However the General Warning caused by the failure of the 48Vdc power supply is for Train B but the logic for a trip is a General Warning for trains simutaneous/y will cause a trip of both trains of SSPS.
- 0. Incorrect, Plausible since RTB will receive a trip signal. However the candidate may not realize that the Joss of 48Vdc caused a B train General Warning. Also, the UV coil on RTB is supplied by 48Vdc. The candidate may think that the loss of one redundant 48Vdc power supply will drop out the RTB UV coil.

Wednesday, January 14, 2015 5:50:52 PM 37
QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. Correct, With the RWST level at <27% on 214 channels an automatic CNTMT sump swap over will occur. However with a failed SI signal on the B train the 1-FCV-63-73 will not have an open signal and thus will remain closed, while the A train valve will open.
B. Incorrect, Plausible if the candidate gets the valves confused for A train vs B train since the A train valve is 63-72 (an even number, but A train) and 63-73 (an odd number, but B train) are not normal configuration for odd vs even for train identifiers.
C. Incorrect, Plausible that the candidate could confuse the logic for CNTMT sump swapover with other permissives that require 314 signals to cause actuation or reset. With one channel failed high and one level above the setpoint the candidate could determine that sump swapover may not occur thus neither valve would open.
D. Incorrect, Plausible that the candidate could determine that CNTMT sump swapover would occur and that just like many other ESF pieces of equipment either train actuation will cause the function to occur (such as TDAFW, EOG)

A. Incorrect, Plausible if the candidate gets the Unit 1 and Unit 2 power supplies confused. Unit 1 uses I & II, while Unit 2 uses Ill & IV thus if they think Unit 1 is like Unit 2 then, and do not recall that the power to the Master Relays are auctioneered then only the "B" train SSPS would have power (bus IV). Also plausible since the second part is correct.
B. Incorrect, Plausible if the candidate gets the Unit 1 and Unit 2 power supplies confused. Unit 1 uses I & II, while Unit 2 uses Ill & IV thus if they think Unit 1 is like Unit 2 then, and do not recall that the power to the Master Relays are auctioneered then only the "B" train SSPS would have power (bus IV). Also plausible if the candidate gets the power supply to the Slave relays confused with U-2, since channel Ill power would be lost to Train A equipment and only Train B equipment would start on Unit 2 for this power configuration.
C. Correct, The SSPS SI Master Relays on both trains will have power since they are supplied with an auctionneering. Train A uses bus I (normal) and bus Ill (alternate) and Train Buses bus II (normal) and bus IV (alternate). lndependantly both trains of Slave relays are will have power, channel I powers Train A and channel II powers train B. Thus both trains of SI equipment will start.

A. Reset the Train B Phase B signal and then the Train B Containment Spray signal B~ Reset the Train B Containment Spray signal ONLY C. Simultaneously Reset BOTH Trains of Phase B D. Reset the Train B Phase B ONLY D/STRACTOR ANALYSIS:
A. Incorrect, Plausible since the setpoint for Phase B and CNMT spray is at the same value that the candidate would think that a Phase B signal would cause a CNMT spray actuation. However Phase B is independant of CNMT spray.
B. Correct, In accordance with ES-1.3 when removing Containment Spray pumps from service the operators are directed to Reset just the CNMT spray actuation signal for the train that will be secured, Thus the minimum action would be to reset just CNMT actuation Phase B to secure the B CNMT spray pump.
C. Incorrect, Plausible if the candidate thinks that the reset logic is the same as the initiation logic which requries the operator to use 2 hands for CNMT spray actuation.
D. Incorrect, Plausible that the candidate would think that by resetting the Phase B signal that it would allow the Train B CNMT spray pump to be shutdown and remain off since the setpoint for Phase B is the same as CNMT Spray.

B. Safety Injection has occurred; Main Steam Line Isolation has NOT occurred.
C'\" Main Steam Line Isolation has occurred; Safety Injection has NOT occurred.
D. NEITHER Main Steam Isolation NOR Safety Injection have occurred.
DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate does not recall that SI and MSLI have been both been blocked by actions within O-G0-7 for a normal plant coo/down.
B. Incorrect, Plausible if the candidate does not recall that the Low pressure SI is blocked by actions in O-G0-7 before RCS pressure is reduced to approx 1920 psig, thus SI and MSLI would be blocked in the stem.
C. Correct, Since SI was blocked as part of the normal plant coo/down in O-G0-7 when RCS pressure is approx 1920 psig, and the SI would not actuate due to low Steam Line pressure of 600 psig. However even though the Main Steam Line Isolation is blocked, the Steam Line Pressure Negative rate of change (100 psi change in 50 secs) setpoint is not blocked and would be active. Thus MSLI would occur and SI would be blocked.
D. Incorrect, Plausible if the candidate recalls that both Low RCS pressure SI and Low Steamline Pressure SI and MSLI are blocked due a normal coo/down and forgets that the Main Steam!ine Neg Rate signal is still active.

A. Incorrect, Plausible if the candidate thinks that the ERCW valves are DC powered valves vs. AC powered valves and could be opened from the MGR, however since there is no power to operate the valves then Local action would be the only way to open the ERCW valves. Also plausible since the second part is correct, at 1. 5 hrs after the trip then -240 gpm would be the minimum flow required.
B. Incorrect, Plausible if the candidate thinks that the ERCW valves are DC powered valves vs. AC powered valves and could be opened from the MGR, however since there is no power to operate the valves then Local action would be the only way to open the ERCW valves.

Unit 2 is in Mode 1.
The TDAFW Pump is tagged out of service.
A Loss of Feedwater causes a reactor trip.
Concurrent with the trip, 28-B 6.9kV SDBD de-energizes on Differential fault.
Assuming NO operator actions have been taken, which ONE of the following describes the Auxiliary Feedwater alignment and approximate flowrate?
A'! 1 and 2 SGs being fed at 220 GPM each B. 1 and 2 SGs being fed at 440 GPM each C. ALL SGs being fed at 110 GPM each D. ALL SGs being fed at 220 GPM each DISTRACTOR ANALYSIS:
A. Correct, With a loss of 28-B SO Board, Only A MDAFW Pump is available. It has a capacity of 440 GPM, and it is aligned to automatically feed 1 and 2 SGs. Thus approximately 220 gpm to each SG.
B. Incorrect, Plausible, since the alignment is correct, however the capacity (440 gpm) is the capacity of the Turbine driven pump, not the motor driven.
C. Incorrect, Plausible if the candidate does not realize that only the A MDAFW is available and it only provides flow to SGs 1 & 2. The capacity would be correct if only one MD AFW pump was running and supplying all 4 SGs.
D. Incorrect, Plausible if the candidate does not realize that 28-B SDBO will not be re-energized by the EOG, thus only the "A" MDAFW is available and it only provides flow to SGs 1 & 2. The capacity would be correct if the candidate gets the flow of the TD AFW pump confused with the MD AFW pump and supplying all 4 SGs.

QUESTIONS REPORT for 1503 RO Exam D/STRACTOR ANALYSIS:
A. Incorrect, Plausible since the candidate could miss the requirement to enter T. S 3.8.1.1 actions. Additionally T.S.3.8.1.1 requires that O-Sl-OPS-082-007. W be performed within 1 hr when only one source of offsite is inoperable.
B. Incorrect, Plausible since the first part is correct. Also plausible that since the pervious crew had performed O-Sl-OPS-082-007. W within the last 8 hrs that the candidate may conclude that the surveillance does not need to be performed again at this time.
C. Correct, Voltage less than 80% (5520v) on any 6.9kV Shutdown Board will cause all 4 EDGs to start via the common emergency start relay and additionally the A train EDGs would tie onto their associated shutdown boards. Thus 1 offsite power supply is inoperable and TIS 3.8.1.1 actions are required. Additionally T.S.3.8.1.1 requires that O-Sl-OPS-082-007. W be performed within 1 hr.
- 0. Incorrect, Plausible since the candidate could miss the requirement to perform the 1hr LCO action. Also plausible since the previous crew had performed O-Sl-OPS-082-007. W within the last 8 hrs the candidate may conclude that the surveillance does not need to be performed again at this time. Also the candidate could determine that both trains of offsite power are inoperable. This condition would not require the O-Sl-OPS-082-007. W to be performed.

A. Incorrect, Plausible since the first part is correct. Also plausible if the candidate does not recognize that an emergency start (whether manually initiated or in an emergency) will bypass the high jacket water temperature trip, thus the EOG will not trip on high temperature.
B. Correct, The Jacket cooling water pump is a shaft driven pump and thus will start when the EOG starts. Also when the EOG is started in Emergency the jacket water high temp will not cause an automatic trip of the EOG.
C. Incorrect, Plausible if the candidate does not recognize that the jacket cooling water pump is a shaft driven pump and thinks that the pump will start at 200 rpm since there are other actions that occur at 200 rpm increasing, (such as setpoint for air start motors, muffler room exhaust fan starts). Also plausible if the candidate does not recognize that an emergency start (whether manually initiated or in an emergency) will bypass the high jacket water temperature trip, thus the EOG will not trip on high temperature.

Unit 1 is operating at 100% power.
Annunciator 1-RA-120A/121A STM GEN BLDN LIQ SAMP MON HI RAD (O-M12-A, B-5) is in alarm.
The indicator for 1-RM-90-120 is reading pegged high and the red light is LIT.
NO other radiation monitor reads abnormally.
1-RM-90-121 responds properly to a source check.
Which ONE of the following identifies the actions to take under these conditions?
A't Ensure 1-FCV-15-44 closed to stop blowdown flow. Notify Chemistry. If monitor has failed, place pink off-normal tags.
B. Ensure 1-FCV-15-44 closed to stop blowdown flow. Entry into AOP-R.01, "Steam Generator Tube Leak", is required.
C. Since 1-RM-90-121 is reading normally blowdown should not have isolated. Notify Chemistry. If monitor has failed, place pink off-normal tags.
D. Since 1-RM-90-121 is reading normally blowdown should not have isolated. Entry into AOP-R.01, "Steam Generator Tube Leak", is required.
DISTRACTOR ANALYSIS:
A. Correct, Either 120or121 will isolate SGBD via 1-FCV-44. Per ARP, the crew ensures SGBD is isolated, validate alarm. Alarm is not valid since the parrallel RM is not in alarm and source checks. If alarm is not valid, then place an equipment inop or off normal tag.
B. Incorrect, Plausible since the first action is required, however entry in to the AOP-R.01 is only required if fora valid RM alarm notjust fora single alarm with no other indications.
C. Incorrect, Plausible since either of the two monitors can cause blowdown to isolate and if the candidate thinks that both 120 and 121 monitors are in service in parallel operation, however normally only monitor is aligned at any one time and with 120 aligned as per the question stem it does not take both in alarm to cause an isolation.
- 0. Incorrect, Plausible since either of the two monitors can cause blowdown to isolate and if the candidate thinks that both 120 and 121 monitors are in service in parallel operation, however normally only monitor is aligned at any one time.

B'."' ERCW supply valves to DGs receive an OPEN signal.
C. ERCW to incore instrument room coolers receive a CLOSE signal.
D. ERCW to CNTMT Spray Heat Exchangers receive an OPEN signal.
DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidates get the isolation signal confused since the ERCW valves for the lower coolers do receive a close signal but only when phase B signal is present not a phase A which could be initiated by the inadvertent SI.
B. Correct, The ERCW to the EDGs all receive an OPEN signal when either unit has an SI actuation. These valves then stroke open to supply cooling water to the EDGs.
C. Incorrect, Plausible if the candidate gets the isolation signals confused since the chill water and the lncore coolers trip on a phase A which is initialed by an SI signal, however the ERCW valves are not affected by these trip signals.
D. Incorrect, Plausible since this a requird ERCW alignment for safe guards equipment using EA-67-1, however this is a manual alignment not an automatic alignment for heat removal.

Unit 1 was at 100% power when a manual SI is initiated.
Which ONE of the following identifies the automatic response of the ERCW system?
1-FCV-67-146, "CCS Hx 1A1and1A2 ERCW Return to Header 8" (1) and O-FCV-67-152, "CCS HXs 081 and 082 Discharge to 8 Discharge Header" (2)

- 8. (1) remains AS IS (2) remains CLOSED C':" (1) remains AS IS (2) REPOSITIONS to 35% position D. (1) OPENS fully (2) remains CLOSED DISTRACTOR ANALYSIS:
A. Incorrect, Plausible based on the misconception that 1-FCV-67-146, CLOSES and O-FCV-67-152 OPENS to 35% position would provide for opening the outlet which allows more cooling for additional SI component heat loads.
B. Incorrect, Plausible if candidate thinks that maintaining status quo, 1-FCV-67-146 and O-FCV-67-152 remaining in their normal conditons, unchanged, considering that SI loads contribute to Component Cooling additional heat load only.
C. Correct, Per 1,2-47W611-67-5; 1-FCV-67-146, remains THROTTLED and O-FCV-67-152 OPENS to 35% position. This arrangement assures adequate cooling water under both normal and emenrgency conditions.
D. Incorrect, Plausible based on potential confusion with the cross-tie valve FCV-67-151 which does remain closed to prevent unbalance and maintain header supply independence, thus leading to the confusion that 1-FCV-67-146, OPENS fully; and O-FCV-67-152, remains CLOSED, to provide enough ERCWflow to the emergency heat loads.

QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate does not recognize which systems get isolated by O-PCV-33-4 and thinks that since Control Air header pressure is rising that the isolation valve is open. However it would be closed. Also plausible if the candidate got confused as to where the sensing pressure to start the Aux Air compressors is from. If they think its Service Air then its header pressure is below the value to start the Aux Air compressors (77 psig) thus they would think that both Aux Air compressors would be running.
B. Incorrect, Plausible if the candidate does not recognize which systems get isolated by O-PCV-33-4 and thinks that since Control Air header pressure is rising that the isolation valve is open. However it would be closed. Also plausible since the second part is correct.
C. Incorrect, Pluasible since the first part is correct, O-PCV-33-4 would be closed at this point. Also plausible if the candidate got confused as to where the sensing pressure to start the Aux Air compressors is from. If they think its Service Air then its header pressure is below the value to start the Aux Air compressors (77 psig) thus they would think that both Aux Air compressors would be running.
- 0. Correct, In accordance with AOP-M.02,at 88 psig in the service air header O-PCV-33-4 closes to attempt to isolate a service air header leak from the instrument air system. As indicated in the stem, with Control air header pressure rising the leak must be isolated. Also with the leak isolating at 88 psig, the Aux Air compressors would not have reached their starting pressure (77 psig and lowering) thus they would not be running.

Which ONE of the following identifies the required action(s), if any, for this failure?
A. Power must remain above 5 x 1o-5% until N-35 is returned to OPERABLE.
B. Enter E-0, "Reactor Trip or Safety Injection," and manually place SRM TRIP RESET : BLOCK switches to RESET.
C. Place the level trip switch for N-35 to BYPASS and continue with plant startup.
CY. Restore N-35 to OPERABLE prior to increasing power above the P-6 setpoint.
DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate thinks that the Rx is above the P-6 setpoint (1 o-4% power) and applies the direction for a failed intermediate range NI above P-6 which would allow the startup to continue.
B. Incorrect, Plausible if the candidate gets the failure Low confused with a High failure of N-35 since a high failure of one channel would cause a Rx Trip and would prevent the SRMs from energizing when below P-6.
C. Incorrect, Plausible since this action is performed for a failed N-35 detector to remove it from service, and since it has been removed from service the action to continue would apply to either a Source Range or Power Range detector for this power level.
D. Correct, In accordance with Tech Spec 3.3.1.1 Action 3 specifies that with Rx power below P-6 if an intermediate range NI fails then the intermediate range channel must be returned to service prior to exceeding P-6.

Unit 1 is at 60% power.
Rod control is in MANUAL.
Charging flow control valve 1-FCV-62-93A is in MANUAL.
A temperature instrument failure results in a greater than 5% difference between Actual and Program pressurizer level.
Assuming NO operator action, which ONE of the following identifies the RTD failure?
A. Thot RTD #1 failed High B. Thot RTD #1 failed Low C~ Tcold RTD #1 failed High D. Tcold RTD #1 failed Low DISTRACTOR ANAL YS/S:
A. Incorrect, Plausible because the That failure would cause a change in the loop Tavg, however the automatic circuit will reject a single failed That signal and will not be passed through to the control system.
B. Incorrect, Plausible because the That failure would cause a change in the loop Tavg, however the automatic circuit will reject a single failed That signal and will not be passed through to the control system.
C. Correct, A single Tcold failure high will not be rejected by the Eagle 21 logic and will cause the Auctioneered High RCS Tavg signal to rise. This signal adjusts the pressurizer level control program setpoint resulting in an increase in the setpoint, compared to the actual level.
D. Incorrect, Plausible since a single Tcold failure is not rejected by the Eagle 21 logic and will cause a change in loop Tave and will cause the loop Tave to decrease.
The Auctioneered signal is High Auctioneered not Low Auctioneered thus the signal would not cause a deviation.

Hydrogen igniters will be (1) and Hydrogen recombiners will (2)
A. (1) off (2) remain in standby B. (1) off (2) be placed in service c~ (1) on (2) remain in standby D. (1) on (2) be placed in service DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate gets the minimum setpoint for energizing the igniters confused with the minimum setpoint for the recombiners and thinks that both will not be needed until Hydrogen concentration is greater than 0. 5%
B. Incorrect, Plausible if the candidate gets the use of the Hydrogen igniters confused with the recombiners and thinks that the recombiners will be placed in service first and the igniters are still in standby during the given plant conditions.
C. Correct, Per E-0 all Hydrogen lgniters are energized and the hydrogen analyzers are turned on (ES-05). If Hydrogen concentration is greater than 0.5% but less than 6% while monitoring during E-1 actions then the Hydrogen Recombiners are also turned on. Thus with Hydrogen concentration less than 0. 5% the recombiners would remain in standby.
- 0. Incorrect, Plausible since the first part is correct, the Hydrogen lgniters are placed in service during LOCA events. Also plausible if the candidate does not recognize that the Hydrogen Recombiners are not placed in service untril hydrogen concentration is greater than 0. 5%.

- 61. 041 K3.02061 Given the following plant conditions:
Unit 1 is at 100% power when turbine impulse pressure PT-1-73 fails high. ""
Thirty (30) seconds after the failure, a reactor trip is initiated by operator action.
Which ONE of the following identifies the expected response of the steam dump system?
The steam dumps will ....
A'! attempt to maintain the RCS Tavg at 552 °F with the reactor trip controller.
B. attempt to maintain the RCS Tavg at 552 °F with the load rejection controller. CP*
C. attempt to maintain the RCS Tavg at 547 °F with the load rejection controller.
D. fully open and remain open until RCS Tavg decreased below 540 °F.
DISTRACTOR ANALYSIS:
A. Correct, The initial effect of PT-1-73 failing high would be that the steam dumps would not open due to not being armed. However if they were armed then the steam dumps would open and lower RCS temperature. When a Rx trip occurs the Rx Trip contoller takes over and attempts to modulate the steam dumps such that RCS tave is maintained at 552°F.
B. Incorrect, Plausible if the candidate thinks that the steam dumps would be controlled by the load reject controller, and confuses the temperature which would maintained RCS temp at 552°F, however the temperature would be controlled by the reactor trip controller. The load rejection controller maintains 547°F C. Incorrect, Plausible if the candidate thinks that the RCS temperature would be controlled by the load reject controller and atttempted to maintain 547°F following the Rx Trip.
- 0. Incorrect, Plausible if the candidate does not recognize that PT-1-73, which is a normal input to steam dump control is not part of the controlling signal when a reactor trip occurs. If the failed signal were still controlling the steam dumps this would be the correct answer, the steam dumps would stay open until closed by low temperature interlock.

Which ONE of the following identifies how readings on the listed radiation monitors would respond to an increase in the radiation level of the gas being released?
O-RM-90-118 Waste Gas Effluent Monitor Shield Building Vent Monitors A. Remain Constant 1-RM-90-400 would increase B. Remain Constant 2-RM-90-400 would increase C. Increase 1-RM-90-400 would increase D."" Increase 2-RM-90-400 would increase DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate does not recognize that the waste gas radiation monitor, O-RM-90-118, would remain in the flow path for the given alignment, and since it is in the flow path, it would see the release. Also, 1-RM-90-400 would NOT show an increase because the release would be out the Unit 2 Shield Building vent.
B. Incorrect, Plausible if the candidate does not recognize that the waste gas radiation monitor, O-RM-90-118, would remain in the flow path for the given alignment, and since it is in the flow path, it would see the release, also the release would be out the Unit 2 vent and 2-RM 400 monitor would show an increase .
C. Incorrect, Plausible since the O-RM-90-118 would show an increase but 1-RM-90-400 would NOT show an increase because the release would be out the Unit 2 Shield Building vent.
D. Correct, with ABGTS a being tagged the release would be out the Unit 2 stack. the gas would pass both the O-RM-90-118 and the 2-RM-90-400 monitors, thus both would show an increase.

- 63. 072 Kl.03 063 Given the following plant conditions:
Both Units are at 100% power.
O-RM-90-103A, Spent Fuel Pit Radiation Monitor, fails HIGH.
Which ONE of the following indentifies the expected plant response?
A. ONLY Train B Aux. Building Isolation dampers close; ONLY Train B Aux. Building General Supply, Exhaust and Fuel Handling exhaust fans trip.
B':" ONLY Train B Aux. Building Isolation dampers close; ALL Aux. Building General Supply, Exhaust and Fuel Handling exhaust fans trip.
C. BOTH Train A and Train B Aux. Building Isolation dampers close; ONLY Train B Aux. Building General Supply, Exhaust and Fuel handling exhaust fans trip.
D. BOTH Train A and Train B Aux. Building Isolation dampers close; ALL Aux. Building General Supply, Exhaust, and Fuel handling exhaust fans trip.
DISTRACTOR ANALYSIS:
A. Incorrect, Plausible since the first part of answer is correct and if the candidate thinks that the entire Aux Bldg vent system is train specific then only the train B components will actuate. However due to relaying both Aux Building General Supply, Exhaust and Fuel Handling Exhaust fans will trip.
B. Correct, The Fuel Pool Area Rad monitors are train specific. O-RM-90-103A will cause a Train B Aux Building Isolation dampers to close. And due to non-train specific relays, both Aux Building General Supply, Exhaust and Fuel Handling exhaust fans trip. It would take both monitors (RM-90-102 and 103) to have both trains of isolation dampers to close.
C. Incorrect, Plausible if the candidate does not know that RM-90-102 would actuate Train A and RM-90-103 will actuate Train B of the Aux Bldg Isolation Dampers to close. This is unlike other automatic isolations. Also plausible however due to relaying both Aux Building General Supply, Exhaust and Fuel Handling Exhaust fans will trip.
D. Incorrect, Plausible if the candidate doesn't know that RM-90-102 and 103 are train specific which is unlike other automatic isolations. Also the second part is correct.

A. At least one CCW pit level above setpoint.
B~ At least one CCW pump breaker must be closed.
C. At least one CCW pump discharge valve must be fully open.
D. At least one waterbox must have both the inlet and outlet MOVs open.
DISTRACTOR ANALYSIS:
A. Incorrect, Plausible if the candidate thinks that CCW pit level above alarm setpoint would be required to assure a heat sink condition exists for dumping steam to the condenser, however this is not the interlock signal for C-9.
B. Correct, For the C-9 Condenser Interlock to be met, at one of the CCW pump breakers must be closed. (it is assumed that if the breaker is closed the pump is running). Only one CCWP is needed to provide a heat sink for steam dump operation.
C. Incorrect, Plausible if the candidate gets confused on the interlock for starting a CCWP instead of making the condenser available since the discharge valves being open if pumps are running or mostly closed is an interlock that needs to be met in order to start a CCWP.
D. Incorrect, Plausible if the candidate gets confused on the interlock for starting a CCWP instead of making the condenser available since water box inlet and outlet MOVs being open is an interlock to starting a CCWP.

- 69. G 2.2.13 069 Given the following plant conditions:
Unit 1 in Mode 5.
1-FCV-62-93, "Charging Flow Control Valve", is selected as a boundary isolation valve for a clearance on the eves charging header.
In accordance with NPG-SPP-10.2, "Clearance Procedure to Safely Control Energy",
which ONE of the following is an acceptable method for tagging 1-FCV-62-93?
A. Ensure the air isolation valve in the open position, place handswitch in closed position and tag both the air isolation valve and the handswitch.
B. v Close the valve, install a jacking device, isolate the air supply and tag both the jacking device and the air isolation valve.
C. Dog the valve closed with its handwheel, isolate the air supply and tag both the handwheel and the air isolation valve.
D. Isolate the air supply to the valve, place handswitch in closed position and tag both the air isolation valve and the handswitch.
DISTRACTOR ANALYSIS:
A. Incorrect, Plausible since this action would close the valve, but it does not provide a safe work boundry. NPG-SPP-10.02 does not allow tagging an air supply valve open and tagging the control switch in the closed position to keep a fail open valve closed. A jacking device is required.
B. Correct, Since FCV-62-93 is a fail open valve a jacking device must be installed to keep the valve in the closed position and the jacking device must be tagged with a hold order card. This would meet the requirements of NPG-SPP-10.02.
C. Incorrect, Plausible however FCV-62-93 does not have a handwheel to dog the valve closed. Examinee may select since some valves do have dogs associated with them and that would be an acceptable method for tagging the valve.
- 0. Incorrect, Plausible however FCV-62-93 fails open and this method would not close the valve, but examinee may confuse the failure mode of the valve and select this option.

- VALVE POSITION LIMIT light is DARK
- OPER AUTO light is DARK
- TURB MANUAL light is LIT In accor:dance with AOP-C.03, "Rapid Shutdown or Load Reduction," which ONE of the following identifies how Turbine load will be reduced?
A'! Intermittently depressing the GV LOWER pushbutton.
B. Intermittently depressing the Valve Position Limiter (VPL) lower pushbutton.
C. Set the load rate to 1%, adjust the setter to 20, and depress the GO pushbutton.
D. Turbine load cannot be reduced, a Turbine trip will be required.
DISTRACTOR ANAL YS/S:
A. Correct, In accordance with AOP-C.03, the operators will use Appendix M to lower Turbine load if turbine controls are in manual. The turbine load is reduced by intermittently depressing the G V Lower pushbutton until desired load is achieved.
B. Incorrect, Plausible because other AOPs!EOPs direct the use of VPL to rapidly reduce turbine load. AOP-S.01, and FR-S.1 both use the VPL to reduce load.
C. Incorrect, Plausible since this the method normally used to reduce turbine load.
However this method cannot be used if the OPER AUTO light is Dark on the EHC panel. This method would not function with EHC controls in Manual.
D. Incorrect, Plausible if the examinee thinks that manual control would not be available and in accordance with AOP-C.03, if turbine load cannot be reduced then a turbine trip would be required.

Thursday, January 15, 2015 9:49:23 AM 74
QUESTIONS REPORT for 1503 RO Exam DISTRACTOR ANALYSIS:
A. CORRECT, the CRO 's designated assembly area is the Main Control Room and EPIP-8 directs the operator to report to the designated assembly area and to swipe badge in the card reader. The cafeteria is the designated assembly area for an AUO assigned to the OSC and the cafeteria card reader would be where their badge is to be swiped.
B. Incorrect, Plausible since the CRO actions are correct, but the AUO would not report to the main Control Room to swipe their badge. The AUO would report to the OSC and swipe in at the cafeteria card reader. Also plausible since during emergencies AUOs are called to MGR to perform actions during EOPs, and EPIP-8 provides guidance on how personnel can be transferred from one station to another as the need arises with the SEO concurrence.
C. Incorrect, Plausible since there is an accountability card reader in the cafeteria and the candidate may think that they are to card into the nearest card reader so as not to delay the accounting of all site personnel. Also the AUO actions are correct, but the CRO would not swipe the card reader in the cafeteria. The CRO would report to the main control room and card in at the card reader in the MGR.
- 0. Incorrect, Plausible since there is an accountability card reader in the cafeteria and the candidate may think that they are to card into the nearest card reader so as not to delay the accounting of all site personnel. However the CRO actions are incorrect. The CRO would report to the MGR and swipe in and the AUO would report to the OSC and swipe in the cafeteria card reader.

A. Correct, In accordance with ECA-0.0 if all shutdown boards are de-energized and the unit is in Modes 1-4, then ECA-0. 0 would be the controlling procedure and has a direct entry for loss of all power during Mode 4 conditions. ECA-0. 0 contains the immediate operator actions for the loss of all AC power while in Modes 1-4.
B. Incorrect, Plausible since parts of AOP-P.01 would be used as directed by ECA-0.0, however AOP-P.01 does not have direct entry for this conditions. If entered the AOP would immediately direct the operators to ECA-0.0.
C. Incorrect, Plausible since AOP-P.05 does deal with loss of power to the SD boards, however the first step of the AOP transitions the operators to ECA-0.0.
D. Incorrect, Plausible since AOP-P.07 does deal with Offsite power conditions that are off-normal or offsite power that is Inoperable, however the first step of the AOP transitions the operators to ECA-0. 0.
