NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 1 Unit 1 is operating at rated power conditions:
0 Both Reactor Building Chilled Water Loop pumps have tripped.
0 Reactor Building Chilled Water is lost.
0 Drywell Cooling has swapped over to RBCCW.
0 No operator actions are taken.
Which one of the following RBCCW actuations occur as a result of the loss of Reactor Building Chilled Water?
A. Reactor Water Cleanup system isolates on high NRHX temp.
B. Reactor Water Cleanup pump trips on high motor winding temp.
C. Containment lnst Gas Compressors trip on low cooling pressure.
D. Reactor Building Sample Coolers isolate on low cooling water flow.
NRC SUSQUEHANNA RO EXAM 516/2008 K&A # 400000 CCW Importance Rating 2.9 QUESTION 1 K&A Statement: K3.01 - Knowledge of the effect that a loss or malfunction of the CCWS will have on the following: Loads cooled by CCWS Justification:
A. Correct - The loss of RB Chilled Water will result in Drywell Cooling swapover to RBCCW. In order to preserve RBCCW cooling, the swapover logic automatically performs a load shed by isolating the RBCCW supply to the NRHX, HV-11315.
Without operator action, the loss of cooling to the NRHX will eventually result in a RWCU isolation on NRHX high temp.
B. In-Correct - For this malfunction, RBCCW cooling is maintained to the RWCU pumps. This is plausible since the RWCU pumps are cooled by RBCCW and trip on high motor temp (135 F). Further, the RWCU pumps trip as a result of the RWCU isolation on valve interlock only. The candidate may remember that RWCU is affected by the RBCCW swapover to drywell cooling and pick this choice.
C. In-Correct - For this malfunction, RBCCW cooling is maintained to the CIG compressors. This is plausible since the CIG Compressors do trip on RBCCW low pressure or high temperature. Candidate may believe all of RBCCW is affected by the swapover.
D. In-Correct - For this malfunction, RBCCW cooling is maintained to the RB Sample Station Coolers. This is plausible since the coolers are cooled by RBCCW and the Chillers (to the coolers) which do trip on low cooling water flow or high temperature.
Candidate may believe only less important loads are load shed on the swapover.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 2 Unit 1 experienced a transient that caused reactor water level to lower to minus
(-) 40 inches.
0 Level has been recovered, RPV level is now +25 inches.
0 The AUTO initiation signals have been reset on RCIC and HPCI.
0 HPCl Aux Oil Pump Handswitch 1P213 in AUTO.
How will HPCl oil system respond, if the operator places HPCl in Manual and lowers the speed to zero (0) RPM? (Assume this was the only operator action taken)
The Auxiliary Oil Pump (AOP):
A. will automatically start when control oil pressure, as sensed at the discharge of the main lube oil pump, is less than 35 psig. Control oil will be maintained and the Stop valve will close. Oil lubrication to turbine and pump bearings will be provided by the AOP.
B. will NOT automatically start when control oil pressure drops below 35 psig during system shutdown and the Stop valve remains open. Oil lubrication to turbine and pump bearings will be provided by the slinger rings.
C. will automatically start when control oil pressure, as sensed at the discharge of the main lube oil pump, is less than 35 psig. Control oil will be maintained and the Stop valve remains open. Pressure Reducing Valve (PCV-15616) will maintain lubricating oil to turbine and pump bearings at 35 to 40 psig.
D. will NOT automatically start when control oil pressure drops below 35 psig during system shutdown and the Stop valve will close. Pressure Reducing Valve (PCV-15616) will throttle open and lubricating oil to the turbine and pump bearings will be lost as oil pressure lowers to 0 psig.
NRC SUSQUEHANNA RO EXAM 5/16/2008 K&A # 206000 HPCl Importance Rating 3.0 QUESTION 2 K&A Statement: K4.13 - Knowledge of HIGH PRESSURE COOLANT INJECTION SYSTEM design feature(s) and/or interlocks which provide for the following: Turbine and pump lubrication: BWR-2,3,4 Justification:
A. In-Correct -With the HPCl auto initiation signal reset, the AOP will not receive an auto start signal. This is plausible since by procedure, the operator is required to place AOP in START when taking manual control, and candidates are accustomed to seeing the AOP Auto start. If they do not know why the pump is placed it in start, they may choose this answer.
B. In-Correct - HPCI turbine and pump bearing are not lubricated by slinger rings and the stop valve closes. This is plausible since this may be confused with RClC valves, which open without oil pressure and RClC has slinger rings to lubricate bearings on startup and shutdown.
C. Correct - Although the HPCI initiation signal is reset, the AOP start logic is sealed-in and the AOP will automatically start on low pressure. The seal-in is maintained provided the handswitch is maintained in AUTO.
D. In-Correct - Although the HPCl initiation signal is reset, the AOP start logic is sealed-in and the AOP will automatically start on low pressure. This is a plausible choice if the candidate believes the seal-in logic is removed when the initiation signal is reset.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 3 Unit 1 is operating at rated power with the following Instrument Air (IA) and Service Air (SA) system lineup:
A IA Compressor, 1K107A is in Lead.
0 B IA Compressor, 1K107B is in Standby.
0 C Dryer Skid (1F116E/F) is in Service.
0 B Dryer Skid (1F116C/D) is in Standby.
0 A Dryer Skid (1F116NB) is 00s for corrective maintenance.
0 Service Air compressors are in a normal lineup.
Control Room observes Instrument Air header pressure is 90 psig, slowly lowering. FUS reports a high differential pressure across the C Dryer skid and appears to be obstructed. The 6 Dryer Skid cannot be placed in service due to a stuck closed outlet Isolation valve.
With IA Header pressure now 80 psig and lowering, which one of the following Crosstie Valves, when opened, can restore air header pressure to supply Instrument Air loads?
A. Unit 1 IA - Unit 2 IA Crosstie Valve, 025091.
C. Unit 1 SA - Unit 1 IA Crosstie valve, PCV-12560.
D. Unit 1 SA - Unit 1 IA PCV Bypass valve, 125143.
NRC SUSQUEHANNA RO EXAM 5/16/2008 K&A # 300000 Instrument Air Importance Rating 3.0 QUESTION 3 K&A Statement: K4.02 - Knowledge of (INSTRUMENT AIR SYSTEM) design feature(s) and or interlocks which provide for the following: Cross-over to other air systems Justification:
A. Correct - The IA Unit to Unit cross-tie will supply IA header loads in this condition since the cross-connect is downstream of the IA Dryers. This is the only crosstie that will work in the event of a Dryer malfunction, a realistic failure mode. The unit crosstie is the last option directed in the offnormal procedure due to the impact on both units and requires Shift Supervision approval.
B. In-Correct - The SA Unit to Unit cross-tie will not restore pressure and supply IA loads since it is upstream of the IA Dryers. This is plausible since without knowledge of the flowpaths, the candidate may know that this is the preferred cross-tie, directed by the offnormal procedure.
C. In-Correct - The SA to IA cross-tie will not restore pressure and supply IA loads since it is upstream of the IA Dryers. This is the normally aligned backup and the PCV auto opens on low pressure. In this case, with a dryer malfunction, pressure at the receivers is good and the valve will not open. This is plausible since the first (and preferred) action in the offnormal procedure. This is normally the success path for a loss of Instrument Air.
D. In-Correct - The SA to IA cross-tie will not restore pressure and supply IA loads since it is upstream of the IA Dryers. This is plausible since the candidate may recognize that at 80 psig header pressure, and know the PCV-12560 should have opened. The offnormal procedure directs the bypass opened around the PCV at this pressure since it assumes it failed. This is normally a success path for a loss of Instrument Air.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 4 During a Unit 1 reactor startup, the ROD OUT BLOCK (AR-104-H03) alarm is received with the following neutron monitoring conditions:
0 SRMs Aand B are Fully Inserted, reading 5 x I O 4 cps.
0 SRM C is Partially withdrawn, reading 1 x I O 3 cps.
SRM D is Partially withdrawn, reading 60 cps.
0 Reactor Period is reading + 50 seconds.
0 IRMs are Fully inserted, reading 4 on Range 1.
Which condition below will clear the ROD OUT BLOCK, so that rod withdrawal and the startup may continue?
The ROD OUT BLOCK will clear if; A. power is allowed to rise until the IRMs indicate above 5 on Range 1.
- 6. SRM Detectors A and B are driven out until the countrate indicates less than I O 3 cps.
C. a control rod is inserted until period is longer than 300 seconds.
D. SRM Detector D is driven in until the countrate indicates greater than 100 cps.

SYSTEM : Changing detector position Justification:
A. In-Correct - The IRM downscale is bypassed on Range 1. This is a plausible distracter since the IRM reading of 5 is a downscale alarm and a rod out block (bypassed on Range 1 in this case).
B. In-Correct - High countrate is 1 x E5. This is plausible since the candidate may confuse this with an IRM (108/120) Rod Block.
C. In-Correct - Period does not cause the rod out block. This is a plausible distracter since the alarm setpoint is 50 seconds, and by procedure, rod withdrawal is stopped and inserted to establish less that 300 second period.
D. Correct - The detector retract permit is causing the rod block. Retract Permissive interlock is not satisfied if count rate is < 100 cps and the detector is not Full In.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 5 Unit 2 is at rated power with Turbine Control Valve testing in-progress. An EHC malfunction during the test resulted in a reactor pressure transient. No operator action was taken and five seconds into the transient, the following readings were observed on all APRM channels:
0 APRM power (FLUX) peaked at 114%, then lowered to pre-transient levels, 0 APRM power (STP) peaked at 109%, then lowered to pre-transient levels.
0 Reactor Recirculation Drive flow read 90%.
0 APRM UPSCALE (AR-203-B06) alarm and Rod Block were received.
Which one of the following statements is correct about the APRM function A. APRMs are operating correctly. The alarm and rod block were provided by the APRM FLUX function.
B. APRMs are operating correctly. The alarm and rod block were provided by the APRM STP function.
C. APRMs are malfunctioning. The alarm was provided by the APRM STP function but the rod block was not expected at this power level.
D. APRMs are malfunctioning. In addition to the alarm and rod block, a full scram was expected from both APRM STP and FLUX functions.
NRC SUSQUEHANNA RO EXAM 5/16/2008 K&A # 212000 RPS Importance Rating 2.7 QUESTION 5 K&A Statement: K5.01 - Knowledge of the operational implications of the following concepts as they apply to REACTOR PROTECTION SYSTEM :
Fuel thermal time constant Justification:
A. In-Correct - STP function provides the alarm and rod block. This is plausible since this is often confused with the Flux function. For the stated powers levels, only an Upscale Alarm and Rod Block are expected.
B. Correct - STP filter introduces a six-second time constant to account for the fact that, during power increase, transient neutron flux leads thermal power because of fuel heat transfer time constants. STP power would lag Flux, which is instantaneous.
Unit 2 EPU Setpoints (nominal TS) are:
a) APRM Neutron Flux High Trip is 118 percent (fixed) - Alarm, vote and rod block.
b) APRM STP High Trip, Unit 2 , 0.62(W) + 62.2% (flow biased, clamped at 113.5%) - Alarm, vote and rod block.
c) APRM STP High Alarm, Unit 2, 0.62(W) + 57.7% (flow biased, clamped @
108 percent) - Alarm and rod block only.
In this question, STP @ 109% will result in an alarm and rod block. Flux @ I 14%
provides no alarms, rod block or scram. Note that the Tech Spec settings are presented and the actual instrument settings are set below these.
C. In-Correct - APRMs are functioning correctly. Candidate may believe this based on the differences in the power readings provided on the NUMAC Operator Display.
Candidate may either incorrectly calculate the setpoint or not know that the APRM Upscale rod block setting is clamped at 108%.
D. In-Correct - APRMs are functioning correctly. Candidate may believe this based on the differences in the power readings provided on the NUMAC Operator Display.
Candidate may believe that the power level was above the rod block and settings.
This is plausible since the STP scram setting is 113.5% (clamped in this case) and confuse with Flux trip setting.

Nuclear boiler instrumentation failures Justification:
A. In-Correct - The MSlV isolation is at - 129 inches; This is a plausible distracter since with the LITS-621-1N026A switch failed and LITS-621-1NO266 failing downscale, the students may believe that a full MSlV isolation signal is present. The isolations are from the same transmitters, but use different switches. Only a quarter isolation exists on the MSlV logic.
- 6. In-Correct - The MSlV isolation is at - 129 inches; This is a plausible distracter since with the LITS-621-1N026A switch failed and LITS-B21-1NO266 failing downscale, the students may believe that a full MSlV isolation signal is present. The isolations are from the same transmitters, but use different switches. Only a quarter isolation exists on the MSlV logic.
C. In-Correct - The logic de-energizes (open) to activate. With LITS-621-1N026A, -38 inch switch failed OPEN; the INBD logic is only waiting for the 1NO266 to indicate below minus (-) 38 inches and close the INBD Isolation valves. This is a plausible distracter since the candidate may believe that with the LITS-621-1N026A failed, no isolation will occur.
D. Correct - N4S logic requires 2-out-of-2 to close (need A and 6 channels for INBD valves or need C and D channels for OTBD valves) Isolation valves with the exception of MSlV logic (MSIVs are l-out-of-2 twice logic). N4S logic de-energizes (open) to activate. With LITS-621-1N026A, minus (-) 38 inch switch failed OPEN; the INBD logic is only waiting for the 1NO266 to indicate < minus (-) 38 inches to close the INBD Isolation valves.

A. In-Correct - ADS valves do not open at t =I02 seconds. With Drywell pressure 1.72 psig, the ADS Drywell pressure bypass timer starts ( 7 minutes or 420 seconds) when level reaches -129 inches. The ADS Logic Initiation timer (102 seconds) is not running.
B. Correct - ADS valves will open at t =202 seconds. With RPV level below -129 inches, the ADS Logic Initiation timer (102 seconds) starts when drywell pressure reaches 1.72 psig (t= 100 seconds). Candidate must also recognize that ECCS pumps (logic permissive) will be running when level reached -129 inches.
C. In-Correct - ADS valves will open at t =202 seconds. With RPV level below -129 inches, answer is plausible if the candidate believes that the valves will not open until the Drywell pressure bypass timer is satisfied (7 minutes or 420 seconds).
D. In-Correct - ADS valves will open at t = 202 seconds. With RPV level below -129 inches, answer is plausible if the candidate believes that the valves will not open until the Drywell pressure bypass timer is satisfied (7 minutes or 420 seconds) which would then start the ADS Logic Initiation timer (102 seconds). From t=O, the time of 522 seconds is t=420 seconds + 102 second timer. This would be correct if the High Drywell pressure signal did not exist at t=lOO seconds.

A. Correct - One pump flow is 240 gpm and due to recent plant mod for power uprate, only one pump will start. Plant designed such that a failure of one squib valve will not prevent full flow to the RPV.
B. In-correct - Either pump can be started. Plausible Distracter since the candidate may believe that with the Asquib valve INOP that he must use the 6SLC Pump and B squib valve. Plausible since the control circuit of the pump interfaces with the squib valve but a failure or loss of power in the squib valve circuit will not affect pump start circuit.

A. In-Correct - At full power, the failed Recirc flow transmitter low would result in an APRM Upscale High condition, Rod Block as well as APRM Upscale Trip condition, one Vote condition, due to flow-biased setpoints exceeded. This is a possible choice if the candidate does not recognize the impact of the failed drive flow signal on the APRM.
B. In-Correct - At full power, the failed Recirc flow transmitter low would result in an APRM Upscale High condition, Rod Block as well as APRM Upscale Trip condition, one Vote condition, due to flow-biased setpoints exceeded. This is a possible choice if the candidate confuses the RPS scram channels and does not understand how the 2-Out-Of-4 Logic Module functions. Also, before the PRNMS modification, one APRM failure did result in a half-scram, similar to one IRM channel failed in 1/2 twice logic.
C. Correct - The flow transmitter instrument failure (0% flow) results in half of the flow signal originally input to the APRM. At full power, the power signal will exceed the flow-biased setpoint for the power signal resulting in an APRM Upscale High, Rod Block and APRM Upscale Trip, Scram Vote. With the 2-Out-Of-4 Logic module, aka Voter module, no scram channels will be tripped in RPS, since it requires two simultaneous votes. With APRM #3 Bypassed, only one vote exists.
D. In-Correct - Only one Vote exists from APRM #I, APRM #3 although tripped is bypassed at the Voter Module. With only one vote, no RPS scram channels are tripped. If the candidate believes two votes exist, then all four scram channels would be tripped, Full Scram and this choice is plausible.

NRC SUSQUEHANNA RO EXAM 5/16/2008 K&A # 209001 LPCS Importance Rating 3.0 QUESTION 19 K&A Statement: K2.01 - Knowledge of electrical power supplies to the following:
Pump power Justification:
A. In-Correct - With 2A202 deenergized, 2D pump should be running with the injection valve closed (no power). This choice is plausible if the candidate does not recognize that a LOCA signal exists (RPV level is given to be above -129 inches).
B. Correct -With a LOCA signal, both pumps have start signals but the 28 pump does not have bus power. Only the 2D pump is running. RPV pressure is below the low pressure permissive (420 psig) and the valve has an open signal and should be fully open (after one minute). However, the Inboard Injection Valve, F005B is powered from 18227, which is powered from the 26 ESS Bus, 2A202. This valve remains closed.
C. In-Correct - A LOCA signal exists along with the low pressure permissive for the injection valves to open. This choice is plausible if the candidate does not recognize that bus power to the 2B pump motor is lost as well as power supply to the F005B.
Candidate may also believe that F005 is the normally open injection valve.
D. In-Correct - With 2A202 deenergized, 2D pump should be running with the injection valve closed. This choice is plausible if the candidate does not recognize that LOCA conditions exist (RPV level is given to be above -129 inches) or if the candidate does not recognize that valve power is from the deenergized bus. Candidate may also believe that F005 is the normally open injection valve.

Startup Bus 20 is out of service and deenergized for maintenance.
0 All 4KV ESS buses are energized.
IA 4KV Bus normal supply breaker, 1A20101 spuriously trips.
0 The A Emergency Diesel Generator (EDG) started and successfully re-energized the bus.
0 Five minutes later, ENGINE LUBE OIL PRESSURE LOW (LA-0521-A01) alarm received at local Panel OC521A and the NPO reports lube oil pressure is lowering.
Which of the below describes the design response of A EDG and 1A 4KV Bus 1A201 to these conditions?
A. The Diesel will trip and the DG output breaker to Bus 1A201 will open.
The 4KV Bus 1A201 will remain de-energized.
- 6. The Diesel will trip and the DG output breaker to Bus 1A201 will open.

A. Correct - With the DG running in Emergency, this Low Lube Oil pressure condition will trip the diesel which in turn, trips the generator output breaker. Based on the electrical lineup and no power available from SUB 20, 1A201 will deenergize.
- 6. In-Correct - The bus will remain de-energized. Based on the electrical lineup and no power available from SUB 20, 1A201 will remain deenergized. This is plausible since this is the normal design response of the 4KV buses and if the candidate does not evaluate the electrical lineup, they could choose this answer.
C. In-correct - This Low Lube oil pressure will trip DG even when running in EMERGENCY. This is plausible since the candidate may believe the Standby motor driven lube oil pump would restore pressure and prevent the shutdown. This oil pressure, based on the alarm and report does, in-fact, result in an immediate diesel shutdown.
D. In-correct - This Low Lube oil pressure will trip DG even when running in EMERGENCY. This is plausible since the candidate may believe the Standby motor driven lube oil pump would restore pressure and prevent the shutdown. This oil pressure, based on the alarm and report does, in-fact, result in an immediate diesel shutdown. Also, in this electrical lineup the alternate supply breaker cannot close because SUB 20 is out of service.

A. Correct - This is a 7 day LCO in accordance with TS 3.6.4.3. SGTS is a safety system required to mitigate an accident sequence.
B. In-Correct - This is not a Tech Spec LCO. This is a plausible distracter since select Drywell fans are required for Tech Specs and a loss of power to Fan 1V414A/B, 1V416A/B, or IV418NB is a TS entry. The stated DW fan is not a Tech Spec required fan.
C. In-Correct -This is not a Tech Spec LCO. This is a plausible distracter since the Reactor Building ventilation system is required for Secondary Containment. A loss of ventilation would require a plant shutdown and potential entry into emergency procedure EO-100-104 Secondary Containment Control.
D. In-Correct - This is not a Tech Spec LCO. This is a plausible distracter since the DG is an emergency electrical power supply and the candidate may believe that the DG Supply fan is a required Tech Spec component.

Justification:
A. In-Correct - Level is in band and maintained using only RWCU letdown (and CRD makeup). Although feedwater is in long-path recirculation, feedwater is not used for level control at this point in the reactor startup.
B. Correct - Using ON-145-004 Step 3.4 and Attachment A, actual RPV level is approximately 35 inches. Level is in band and will be maintained using RWCU letdown (and CRD makeup) at this point in the startup, prior to rod withdraw IAW GO-100-002 Step 5.10.
C. In-Correct - Actual RPV level is 35 inches. Candidate may believe level is high if the instruments are not correctly interpreted correctly using ON-I45-004 Attachment A.
Actual level of 50 inches is plausible if the candidate believes NR level is accurate and usable.
D. In-Correct - Actual RPV level is 35 inches. Candidate may believe level is high if the instruments are not correctly interpreted using ON-145-004 Attachment A. Actual level of above 60 inches is plausible if the candidate incorrectly plots extended and wide range on the curves. Further, level is maintained using only RWCU letdown (and CRD makeup).

Injection Mode Importance Rating 3.5 QUESTION 23 K&A Statement: K5.02 - Knowledge of the operational implications of the following concepts as they apply to RHWLPCI: INJECTION MODE (PLANT SPECIFIC) : Core cooling methods Justification:
A. In-Correct - The Minimum Zero Injection Water level, aka. steam cooling does not establish ACC in this condition since LPCl is injecting. This is a plausible distracter since steam cooling may be used if the water level is below TAF and no makeup source is available. The candidate may believe ACC exists.
B. In-Correct - In this condition, maintaining the reactor depressurized with more than 2 SRVs open does not ensure ACC. Flooding to the MSL to provide core submergence is a method of ensuring ACC. This is a plausible distractor since depressurization is a required condition stated in the EOPs but again in no way assures ACC.
C. Correct - This condition assures ACC in the given conditions RPV level indeterminate during an ATWS. Adequate Core Cooling is accomplished by maintaining minimum steam cooling pressure during an ATWS. The candidate will evaluate that the stated combination of SRVs and RPV pressure is acceptable for maintaining ACC.
D. In-Correct - The Minimum Zero Injection Water level, aka. steam cooling stated here does not establish ACC. Further, use of this strategy is not permitted in an ATWS condition. This is a plausible distracter since steam cooling with injection is a method of adequate core cooling and the candidate may believe ACC exists.

A. Correct -When running in Test, the E DG will immediately shutdown upon receipt of a LOOP or LOCA signal. This will automatically close the ESW supply and return valves to ensure ESW supplied to the diesels and the E DG will immediately shutdown (on the Emergency Service Water Interlock).
- 6. In-Correct - The ESW supply and return valves will automatically close and in-fact it is this signal which shuts down the diesel automatically. This is plausible since normally, during test operation, the ESW valves are manually opened prior to the DG test and closed when the test is completed, DG shutdown.
C. In-Correct - The ESW supply and return valves will automatically close and in-fact it is this signal which shuts down the diesel automatically. This is plausible since normally, during test operation, the ESW valves are manually opened prior to the DG test and closed when the test is completed, DG shutdown. The E DG ESW supply and return valves are DC powered from an independent battery system in the E Diesel, for this very scenario.
D. In-Correct - The ESW supply and return valves will automatically close and in-fact it is this signal which shuts down the diesel automatically. This is plausible since normally, during test operation, the ESW valves are manually opened prior to the DG test and closed when the test is completed, DG shutdown. Further, though this would not occur in this case, the intercooler ESW temperature control valves do fail open on loss of air or control power.

A. Correct -With the leak on the F008, the FOO9 will close to isolate the leak at + I 3 inches and the Aloop pumps get a trip signal (A RHR running) on interlock. In addition to the F008 and FOO9, both F015A and F015B will isolate at + I 3 inches in the SDC mode and RPV level will stabilize. Since level is above -129 inches, the RHR pumps will not receive a start signal. RHR remains in the Shutdown Cooling Mode until the operator resets both RHR Loop A/B Shutdown Cooling Reset pushbuttons to convert to LPCl mode.
- 6. In-Correct - The leak is isolated at + I 3 inches. Both FOI5A and FOI56 valves are automatically isolated in the Shutdown Cooling Mode. This is plausible since - 38 inches is an isolation and RHRSW pump trip. The candidate may also not believe both the F015A and F015B (normally associated with LPCl injection) get closed signals.
C. In-Correct - The leak is isolated at + I 3 inches. Since level is above -129 inches, the RHR pumps will not receive a start signal. This is plausible if the candidate believes the isolation does not occur until -129 inches when RHR will convert from Shutdown Cooling to LPCI.
D. In-Correct - The leak is isolated at + I 3 inches. Since level is above -129 inches, the RHR pumps will not receive a start signal. This is plausible if the candidate believes the leak is not isolable (confuses the leak location since the F008 is actually the Outboard isolation valve) and then level would lower to -129 inches.

A. In-Correct -The loss of power and N4S isolation will isolate chilled water to both Recirc pumps (inboard valves of one pump and outboard valves of the other).
Plausible choice if the candidate believes the isolation is an Aisolation instead of a Div 1 isolation.
- 6. In-Correct - The loss of power and N4S isolation will isolate chilled water to both Recirc pumps (inboard valves of one pump and outboard valves of the other).
Plausible since the difference between these cooling loop supplies, difference between N4S and DWClS logics and valve isolations is a common misconception.
Also, candidate may believe the isolation is an A isolation instead of a Div 1 isolation, affecting only the A pump. Also plausible since a momentary loss of power to RBCCW containment isolation valves does occur, but is not an isolation and the containment isolation valves immediately reopen when buses reenergize.
C. Correct - Loss of SUB 10 will cause 1A201 to swap to alternate power, 1A RPS EPA Breakers will trip, de-energizing A RPS bus causing DIV 1 N4S Isolation. Loss of Reactor Building Chilled water to both Rx Recirc Pumps will occur (inboard valves of one pump and outboard valves of the other). Valve logics must be manually reset for each pump.
D. In-Correct - The loss of power and N4S isolation will isolate chilled water to both Recirc pumps (inboard valves of one pump and outboard valves of the other). This isolation will not result in a sustained loss of RBCCW since the bus loss is momentary and the containment isolation valves will reopen when buses reenergize.

Recirculation runbacks: Plant-Specific J ustif ication :
A. In-Correct - On Unit 2, a RFPT trip results in an immediate Recirc Runback to Limiter
- 2 (48%). This would be correct for Unit 1, since pre-modification, a RFPX trip requires a concurrent confirmatory 30 inch low RPV level signal to initiate the runback to Limiter #2.
B. In-Correct - On Unit 2, a RFPT trip results in an immediate Recirc Runback to Limiter #2 (48%) not Limiter # I (30%). A low level signal by itself can result in a Limiter #I and is a possible choice if the candidate confuses the initiating runback signals.
C. In-Correct - On Unit 2, a RFPT trip results in an immediate Recirc Runback to Limiter
- 2 (48%). Since the A RRP is locked, the A RRP will not automatically accur and the pump speed must be lowered locally at the Jordan positioner. A runback does not automatically unlock a scoop tube. This would be correct if both RRP scoop tubes were in normal.
D. Correct - On Unit 2, a RFPT trip results in an immediate Recirc Runback to Limiter
- 2 (48%). Since the A RRP is locked, the A RRP will not automatically occur and the pump speed must be lowered locally at the Jordan positioner. NOTE: This is a Unit difference until the completion of U1-15 RIO modification. For power uprate, as presently installed on Unit 2, the Recirc Runback modification removes the 30 inch level confirmatory signal to provide an immediate runback.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 31 Unit 2 is in MODE 1 at 100% rated power.
The following alarms are received:
FW LOOP B PANEL 2C102 TRBL (AR-202-H07) 5B LEVEL HI (LA-202-A02) 0 5B LEVEL DUMP VALVE NOT 100% CLOSED (LA-202-C02)
Upon investigation it is discovered that a level control malfunction has occurred and the PCO observes 5B Feedwater Heater level is 12 inches, rising.
As level rises, predict the effect when the Hi-Hi Level Trip setpoint is reached; AND What procedure action is required to mitigate this event?
A. The 5B Feedwater Extraction Steam Isolation Valve will ISOLATE and rising power will raise the potential for fuel failure due to Pellet Clad Interaction. Perform ON-247-001 Loss of Feedwater Heating Extraction Steam and reduce power to 585% power.
B. The 58 Feedwater Extraction Steam Isolation Valve will ISOLATE and ensure the Reactor Recirculation pumps runback. Perform ON-247-001 Loss of Feedwater Heating Extraction Steam and ON-264-002 Loss of Reactor Recirculation Flow to reduce power to 585% power.
C. The B Feedwater Heater String will ISOLATE and ensure the Reactor Recirculation pumps runback. Perform ON-247-002 Loss of Feedwater Heating String and ON-264-002 Loss of Reactor Recirculation Flow to reduce power to ~ 8 5 % power.
D. The B Feedwater Heater String will ISOLATE and when feedwater temperatures lower, reactor power will rise above 100% power. Perform ON-200-004 Reactor Power Greater Than License Limit and initiate prompt action to reduce power at 4 0 0 % power.

A. Correct - Hi-Hi level in 5B FW Heater will cause the extraction steam isolation valve to close. FW temperature will lower causing reactor power to increase, action must be taken to lower reactor power. ON-147-001 Loss of Extraction Steam directs the operator to immediately lower reactor power to 4 5 % power due to an immediate concern for fuel damage due to PCI.
B. In-Correct - Extraction Steam Isolation does not cause a Reactor Recirc Runback.
Plausible Distracter; FW Heater 1 or 2 will cause a Heater String Isolation on Hi-Hi level and a Recirc runback.
C. In-Correct - Feedwater heater 5B is not a string isolation on Hi-Hi level. Plausible Distracter; Feedwater Heaters 1 or 2 will cause a Heater String Isolation on Hi-Hi level and a Recirc runback.
D. In-Correct - Feedwater heater 5B is not a string isolation on Hi-Hi level. Plausible Distracter; Feedwater Heaters 1 or 2 will cause a Heater String Isolation on Hi-Hi level and because 5B would cause power to rise > 100%.

A. In-Correct - FV-10702NB fail closed on a loss of IA and result in a SJAE Isolation on Low Dilution steam flow. If they failed open, it is plausible that a SJAE isolation could eventually occur on High Recombiner Discharge temperature.
- 6. In-Correct - FV-10702NB fail closed on a loss of IA and result in a SJAE Isolation on Low Dilution Steam Flow. If they failed open, it is plausible that a Recombiner shutdown could eventually occur on High Condenser temperature.
C. Correct - The FV-10702NB control valves automatically maintain dilution steam flow based on two flow controllers at 9350 Ibm/hr. The valves fail closed on a loss of IA (or power), resulting in a low dilution steam flow and SJAE isolation.
The Offgas system is an integrated system that includes the Air Removal system and the Recombiner system. As seen below, the signals that cause an isolation versus a shutdown are often confused. The following conditions result in a SJAE Isolation (automatically closes the SJAE suction valves HV-10716, 10717, 10718, and 10719):
0 Low Dilution Steam Flow Trip at 8000 Ibs/hr.
0 Low Recombiner Inlet Temperature at 225OF, 0 High Recombiner Discharge Temperature at 925OF, 0 Low Motive Steam Jet Condenser Cooling Water Flow at 110 gpm, 0 Low Recombiner Condenser Cooling Water Flow at 275 gpm, 0 Air Removal Emergency Shutdown (ARESD)
A Recombiner shutdown (automatically closes the Recombiner process and steam supply valves) is the direct result of a Recombiner Condenser Outlet Temperature High-High at 250 OF.
D. In-Correct - FV-10702NB fail closed on a loss of IA and result in a SJAE Isolation on Low Dilution Steam Flow. As stated above, SJAE Isolation and Recombiner Shutdowns are often confused.

0 HPCl and RClC are controlling level + I 3 to +54 inches.
0 Reactor pressure is 940 psig, slowly lowering.
0 SPOTMOS temperature is 92OF, slowly rising.
0 Supp Chamber pressure is 5 psig, slowly rising.
0 Drywell pressure is 10 psig and slowly rising.
Five minutes later, the following information is reported:
'A Loop RHR is in Suppression Chamber Sprays.
0 Supp Chamber pressure is 6 psig, slowly rising.
0 Drywell pressure is 11 psig, slowly rising.
0 SPOTMOS temperature is 115" F, slowly rising.

Torus/Pool Spray Mode Importance Rating 4.2 QUESTION 37 K&A Statement: 2.4.31 - Emergency Procedures / Plan: Knowledge of annunciator alarms, indications, or response procedures. (RHWLPCI:
Torus/Pool Spray Mode)
Justification:
A. In-Correct - If the vapor space contained steam following initiation of sprays, a reduction in Drywell pressure should occur. Use of a second loop of Suppression Chamber sprays is not permitted since a single spray header exists by design with either RHR loop supplying that header at a maximum of 500 gpm.
B. Correct - Vapor space pressure is caused by accumulation of non-condensibles (nitrogen in this case), and the use of sprays in the Supp Chamber vapor space will have little or no effect on SC pressure. Drywell spray is not permitted in this condition until Suppression Chamber pressure exceeds 13 psig.
C. In-Correct - Supp Chamber sprays with a 115 O F water temperature is not too high to reduce vapor space pressure. At this point, Supp Chamber pressure is more a function of Supp Pool level than temperature. Supp Chamber airspace temperature will reach an equilibrium with the spray water temperature due to convective heat transfer. Further, using sprays from RHRSW is not warranted in this condition.
D. In-Correct - If vacuum breaker valves were leaking, the differential pressure between the Drywell and Suppression Chamber vapor space would be a value less than 5 psid.

A. In-Correct - The TCV will not throttle close but fast-close (fast acting solenoid valves actuate) on Power Load Unbalance (PLU) signal. This is plausible since this is the CV will throttle to control pressure if the PLU was not armed or load reject was below the threshold (40% power to load unbalance).
B. In-Correct - PLU senses the load reject and will cause an immediate TCV Fast Closure and scram. The IV will not throttle close until an overspeed condition is sensed. Plausible since the purpose of the Intercept Valves is to close on overspeed (105-107%) and fast-close in the event of rapid overspeed (5% trigger step change),
which is possible during a load reject transient. The Unit will not stay online.
C. Correct - The Power Load Unbalance (PLU) circuitry monitors generator output current (load) and compares it to Turbine power as sensed by Cross-around steam pressure (power). If a rate-sensitive load unbalance of >40 percent in 35 msec is detected, the circuit actuates to protect the Turbine from load reject and avoid turbine generator damage as well as a potential overspeed condition. Scram occurs due to TCV fast closure with power > 30%. A turbine trip follows on either reverse power or sync breaker opening and these offnormal procedures are entered.
D. In-Correct - PLU sense the load reject and cause an immediate TCV Fast Closure and scram. The IV will not throttle close until an overspeed condition is sensed. IVs also do not cause an immediate RPS scram. Plausible since the purpose of the Intercept Valves is to close on overspeed (105-107%) and fast-close in the event of rapid overspeed (5% trigger step change), possible during a load reject transient.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 39 The following conditions exist on Unit 1:
0 A large leak has occurred in the Drywell.
0 Suppression Pool level is 19 feet, steady.
0 Suppression Chamber Sprays are in-service.
0 Drywell sprays are being initiated.
When the Drywell Spray Outboard Isolation Valve, HV-151-FO16A was throttled open to establish the required spray flow, the valve continued stroking to the full open position, instead of stopping when the handswitch was released.
In accordance with EO-000-103, "PC Control" bases, which one of the following describes the concern of initiating the maximum Drywell Spray flow due to the valve stroking full open?
A. RHR Pump motor overcurrent trip due to excessive flow and runout.
B. Drywell Spray Header and piping damage due to water hammer.
C. RHR pump damage due to exceeding RHR Vortex and NPSH Limits.
D. Containment damage due to exceeding design differential pressure.

- Drywell integrity: Plant-Specific Justification:
A. In-Correct - This is not a concern since RHR pumps are rated for 12,200gpm @ 204 psig and are provided with an orifice to restrict flow to 13,500 gpm to prevent pump runout.
B. In-Correct -This is not a concern since the piping is normally maintained filled and vented and drywell spray header is the high point inside the containment.
C. In-Correct - This is not a concern since Suppression Pool level is above the level specified in the EOPs for Vortex and NPSH concerns.
D. Correct - In accordance with the EOP bases, the concern is for evaporative cooling that occurs when water is sprayed into a superheated atmosphere. The water at the surface of each droplet is heated and flashed to steam until the surrounding atmosphere saturates, absorbing heat energy from the atmosphere. In the drywell, this cooling process results in an immediate, rapid and large reduction in pressure at a rate much faster than can be handled by the vacuum breakers (even if they were full open at time of spray initiation). Analytical results indicate drywell pressure drops of up to 12 psig can occur in less than 0.5 seconds. Unrestricted operation of drywell sprays could thus cause an excessive negative differential pressure to occur between the drywell and suppression chamber.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 40 ON-149-001, Loss of RHR Shutdown Cooling Mode directs the operator to maintain RPV water level 1+45 inches when RHR Shutdown Cooling is lost.
Which one of the following is the basis for this action?
A. To ensure the water in the annulus is high enough to provide a flowpath from core shroud to the downcomer for circulation.
B. To ensure the feedwater spargers effectively mix the feedwater added to prevent stratification in the vessel downcomer area.
C. To ensure Narrow Range Level instruments remain on-scale for continuous level and temperature monitoring.
D. To ensure the water from the annulus area of the Reactor flows into the core shroud as level decreases for circulation.
NRC SUSQUEHANNA RO EXAM 5/16/2008 K&A # 295021 Loss of Shutdown Cooling / 4 Importance Rating 3.6 QUESTION 40 K&A Statement: AKI .04 - Knowledge of the operational implications of the following concepts as they apply to LOSS OF SHUTDOWN COOLING : Natural circulation Justification:
A. Correct - Level is raised to ensure communication between the shroud and the annulus via the moisture separator skirt. Raising level promotes natural circulation by allowing the level in the heat source (shroud) to rise and flow to the heat sink (annulus or downcomer).
B. In-Correct - This is not the basis. Raising level does not prevent stratification in the downcomer area and has nothing to do with the FW spargers. Plausible since preventing stratification and good mixing is a desirable condition within the reactor core area.
C. In-Correct - This is not the basis. Though it may be on-scale, the NR level instrument is not used for RPV level while in shutdown cooling. Further, temperature monitoring is not assured regardless of RPV level. The idea of level and temperature is plausible since there is correlating discussion of monitoring temperature using RPV flange and metal temperatures.
D. In-Correct - This is not the basis. This is a reverse of B if the candidate does not understand the mechanism by which natural circulation occurs. Coolant does not flow from the annulus into the shroud.

POWER : Loss of breaker protection Justification:
A. Correct - On the loss of control power to the breaker, all automatic protective trips are disabled, therefore pump will continue to operate. The pump can only be tripped locally at the breaker.
B. In-Correct - All automatic protective trips are disabled at the breaker. This is plausible since the pump will continue to run and the candidate may believe protective features are powered separately.
C. In-Correct - The operating CRD pump will not trip. This is plausible since there are pump logics in the plant that will trip on a loss of control power, e.g., Reactor Recirc Pumps that automatically trip on loss of 125 VDC control power. In the case of the Control Rod Drive pumps, the auto trips are disabled with a loss of control power.
This is a plausible choice if the candidate believes this is a fail-safe feature.

A. In-Correct - RPV level cannot be determined since Wide Range level is below MIL.
However, the candidate may interpret the status of wide range recovering as good level. The off-calibration condition makes the trend capability plausible.

Emergency generators Justification:
A. In-Correct - The bus will not remain deenergized. ESS Transformer T-201 (0x203) is the alternate supply for Unit IA ESS Bus, therefore 1A20109 Breaker will not close. The DG will start and energize the bus via the 1A20104 DG output breaker.
This is a plausible choice if the candidate does not recognize the bus condition and breaker alignment.
B. In-Correct - On the loss of T-10, the normal supply breaker 1A20101 will trip open on undervoltage. Since the alternate source is not available, the diesel will start and energize the bus via the 1A20104 DG output breaker.

A. In-Correct - This is not the basis for the step. This is a plausible choice since the turbine trip and generator lockout would result in the fast transfer of Aux Buses. The operators are required to ensure the transfer of house loads following the generator trip.
B. In-Correct - This is not the basis for the step. This is plausible since the candidate may recognize the RRPs would be tripped on either the EOC-RPT trip or the low RPV level at -38 inches. Since restoring core circulation is preferred post-scram, the candidates may believe that this is the reason.
C. In-Correct - This is not the basis for the step. This is plausible since the candidate may confuse the fact that RRPs trip on low RPV level (albeit -38 inches) and maintaining core circulation is preferred post-scram as the reason.
D. Correct - The EOPs direct this step to avoid an unnecessary Plant Auxiliary Load Shed signal. In anticipation of ECCS loads, either a Low RPV Level -129 inches (or Hi DW pressure 1.72 psig) with a main generator lockout will initiate Plant Aux Bus Load Shed.

A. In-Correct - Isolating the 1A TBCCW SW inlet and outlet isolation valves (109086 and 109087) will not isolate the leak, since ESW transfer valves, including HV10943A3, are inside the manual isolation valves. Placing ESW in-service on the 1A TBCCW heat exchanger will simply result in an ESW leak.

- 3. In-Correct - Closing the 1A TBCCW SW inlet isolation valve (109086) will not isolate the SW leak, since transferring to ESW will cause an ESW leak, as discussed above.
C. In-Correct - Swapping to 1B TBCCW HX will restore cooling. However, the leak cannot be isolated by transferring to ESW, as discussed above.

- Instrument air system valves: Plant-Specific At Susquehanna, the Scram Valves are indirectly supplied by the the Instrument Air Header via the Scram Air Header. Since there is no direct monitoring of the Scram Air Header in the Control Room, the Scram Valves are considered IA system supplied valves, like e.g.,MSIVs, in the Loss of Instrument Air procedure.
Justification:
A. In-Correct - Reactor scram is not required until IA pressure reaches 4 5 psig. MSlV closure is not the reason, since this is an analyzed transient and scram. This is plausible since MSlVs will drift closed ( 4 0 psig) and cause a significant transient.
B. In-Correct - Reactor scram is not required until IA pressure reaches 435 psig.
C. In-Correct - MSlV closure is not the reason, since this is an analyzed transient and scram. This is plausible since MSlVs will drift closed ( 6 0 psig) and cause a significant transient.
D. Correct - Manual reactor scram is performed when Instrument Air Header pressure reaches 5 5 psig. From ON-I 18-001 bases: It is of the utmost importance that the reactor be scrammed prior to the scram inlet and outlet valves drifting open (slow loss of instrument air pressure). Scram valves drifting open can result in random Control Rod insertion with the potential for scram discharge volume in-leakage and abnormal Core flux patterns. A manual scram is required since this can create an unanaIyzed core condition.

Suppression pool cooling Justification:
A. Correct - All Unit 2 RHR pumps start on the LOCA. All Unit 1 RHR pumps receive a trip signal. The RHR pumps are interlocked (breaker to breaker) such that a Unit 1 RHR pump can only be restarted when the associated Unit 2 RHR pump is overridden, Le., manually stopped on Unit 2. Then the associated Unit 1 pump can be manually started for Supp Pool Cooling (or any other mode of RHR).
B. In-Correct - All Unit 1 RHR pumps receive a trip signal. Any running RHR pumps will be tripped on the Unit 2 LOCA signal. This is plausible since the LOCNfalse-LOCA logic deals with preferred and non-preferred pumps. Preferred pump logic is A, B on Unit 1 and C,D on Unit 2.
C. In-Correct - All Unit 1 RHR pumps receive a trip signal. Any running RHR pumps will be tripped on the Unit 2 LOCA signal. This is plausible since the LOCNfalse-LOCA logic deals with preferred and non-preferred pumps. Preferred pump logic is A, B on Unit 1 and C,D on Unit 2.
D. In-Correct - All Unit 1 RHR pumps receive a trip signal. The RHR pumps are interlocked (breaker to breaker) such that a Unit 1 RHR pump can only be restarted when the associated Unit 2 RHR pump is overridden, i.e., manually stopped on Unit

A. In-Correct - Initial ATWS power is -25%. This is a plausible distracter since the candidate may assume since no APRM power given, power level must be at 65%,
the power level associated with natural circulation at the 100% rod line.
B. In-Correct - Initial ATWS power is -25%. This is a plausible distracter since the candidate may assume since no APRM power given, power level must be at 55%
assuming steam flow to the bypass valves. MSlVs are closed in this case.
C. Correct - Initial ATWS power is -25% since each SRV approximately 850,000 Ibm.hr steam flow or = 6% power. Emergency operating procedures requires the use of alternate indications of power to determine Initial ATWS Power.
D. In-Correct - Power level can be determined by the number of SRVs open. This is a plausible distracter since the candidate may recognize that APRMs are deenergized and the bases state that if you have no alternate methods, then you can assume
>5% and cannot be determined. Power can be determined in this case.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 52 Unit 1 is in MODE 5. Refueling operations and movement of irradiated fuel assemblies are in progress. Fuel Pool level lowered and stabilized at 20.2 feet.
Plant personnel are investigating and refueling has been stopped.
Regarding the Technical Specification (TS) LCO for the Spent Fuel Storage Pool Level, determine if the current fuel pool level is ABOVE or BELOW the MINIMUM level over irradiated fuel assemblies and the technical basis for this level?
A. Fuel pool is ABOVE the minimum level for the analysis since adequate inventory is available to maintain the spent fuel pool <I 15°F over the next 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> following a loss of fuel pool cooling event.

A. In-Correct - The level is below the Tech Spec Limit (LCO) 222 feet and 21 feet, the actual analysis limit. This is not the technical basis for maintaining level over irradiated fuel assemblies. This is a plausible distractor since the fuel pool analysis do require fuel pool temperature be maintained below 1 15 OF.
- 6. In-Correct - This is not the technical basis for maintaining level over irradiated fuel assemblies. This is a plausible distractor since adequate inventory for fuel pool boiling is analyzed based on the decay heat load and administratively maintained by cross-connecting the fuel pools.
C. In-Correct -This is not the technical basis for maintaining level over irradiated fuel assemblies. This is plausible since the level in the pool does provide shielding and minimum levels are administratively controlled for personnel exposure during operations. SPING operability is affected by refuel floor background radiation levels.
D. Correct - The level is below the Tech Spec Limit (LCO) 222 feet (21 feet is the actual analysis limit stated in the bases). This level is based on a Fuel Handling Accident.

A. Correct - Given the above conditions, EO-100-103 Primary Containment Control, PCIP-7 andlor DW/T-5 requires spraying the drywell to lower containment pressure and/or pressure. Since ACC is assured and RPV pressure is high, this action is required to control primary containment parameters.
B. In-Correct - RPV Flooding IAW EO-100-114 is not required. This is a plausible distractor since the candidate must evaluate the plant parameters and determine if RPV level is usable.
C. In-Correct - Aligning all RHR pumps for LPCl injection is not required. EOP bases address this exact situation where it is appropriate to address the containment based on current RPV pressure and level. Core Cooling is assured by core submergence.
This is plausible since with level at -91 inches, lowering at 2 inchedmin, it will take 35 minutes to reach TAF and the EOP provides guidance for aligning RHR to LPCI.
D. In-Correct - Rapid Depressurization IAW EO-100-112 is not required. This is plausible since rapid depress would be required if HCTL limits of Figure 2 or PSL limits of Figure 4 were threatened. Also plausible since Drywell temperature is 285°F rising and a rapid depress is directed at 340°F. Candidate may also believe that a rapid depress is needed to inject with low pressure ECCS.

Justification:
A. In-Correct - Given the above conditions, the voltage regulator will transfer to the Manual Voltage Regulator.
B. In-Correct - Given the above conditions, the voltage regulator will transfer to the Manual Voltage Regulator. This feature would have already occurred since the automatic regulator has control circuits to allow field forcing to assist in supporting the power system during emergencies (can last for thirty seconds or more depending on the magnitude of the excitation level). The generator field current limit is adjusted to 5876 amps DC if the Exciter Stator Overvoltage protection actuates. However, after 5 seconds, the regulator will automatically transfer to Manual, action is guaranteed once the overcurrent alarm is reached.
C. In-Correct - Given the above conditions, the voltage regulator will transfer to the Manual Voltage Regulator. This is plausible since other generators, e.g., Emergency diesels have a backup voltage regulator, however the Main Generator is not provided with a backup auto regulator.
D. Correct - After 5 seconds with the Overvoltage and Overcurrent conditions, the voltage regulator will swap to the Manual Regulator. Operator action is required to maintain field amps and the Generator output within procedure limits.

Limiting heat additions Justification:
A. In-Correct - This is not the basis. This is plausible since this statement is the basis for the Pressure Suppression Limit.
B. In-Correct - This is not the basis. This is plausible since this is the basis for maintaining Suppression Pool level 38 feet.
C. Correct - The shape of the HCTL is determined by several competing factors related to the suppression chambers ability to absorb all energy from an RPV depressurization without exceeding 65 psig in the suppression chamber (operating limit of the suppression chamber vent).
D. In-Correct - This is not the basis. This is plausible since high pool temperature affects NPSH and is bounded by the Vortex Limit Curve (SPL vs. Pump Flow) aides in maintaining ECCS capability.

- 6. Correct - If an individual scheduled to fill a required position calls off or does not report to fill that position, Shift Supervision will hold over a qualified individual to fill the position until a qualified replacement can take the position.
C. In-Correct - It is not permissible to drop below the minimum manning for this condition.

Justification:
A. Correct - IAW EO-000-105 Table 11 and Step RR-5 Scram the reactor and enter EO-100-102. The purpose of entering EO-100-102 is to commence a cool down to limit the energy that is released.
B. In-Correct - EO-100-104 direct the operator to scram the reactor and enter EO-100-102. This is a plausible distracter since step SC-2 states that if RB or SGTS SPING RAD Release exceeds Hi-Hi and ZONES not isolated perform ES-070-001. Also, with RB SPING out of service, the candidates may believe this is the correct action.
C. In-Correct - A rapid depressurization is not required. This is plausible since EO-100-105 requires a rapid depressurization when unmonitored release rates are unknown or Containment Rad 25OWhr D. In-Correct - EO-100-105 requires entering EO-100-102 to commence cool down to limit release. This is plausible since there are other overriding bases in the other conditions to delay the depressurization to keep fuel isotope in the fuel rods.

C. Correct - Based on the CDI and FW conductivity readings, the problem is in a waterbox and power must be reduced to <75%to limit the concentration in the vessel. A subsequent power reduction to <60% is not required until the affected waterbox is removed from service for ALARA.
D. In-Correct -This action is not correct. This is plausible if the candidate misinterprets the chemistry levels are above the Action 3 or Tech Spec levels, either of which directs a plant shutdown and cooldown.

NRC SUSQUEHANNA RO EXAM 5/16/2008 QUESTION 75 In accordance with NDAP-QA-0320, Special, Infrequent Or Complex Test / Evolutions (SICTE), Which one of the following outage activities meets the definition of a SICTE?
A. Performance of the Div 1 LOCNLOOP and DG test in accordance with SE-124-107.
B. Performance of the Comprehensive ESW Flow Verification Loop A test in accordance with SO-054-A08.
C. Performance of the Primary Containment Integrated Leak Rate test in accordance with SE-100-003.
D. Performance of the post-installation test of temporary Shutdown Decay Heat Removal (SDHR) system in accordance with TP-135-011.
NRC SUSQUEHANNA RO EXAM 5/16/2008 K&A # 2.2.7 Equipment Control Importance Rating 2.9 QUESTION 75 K&A Statement: 2.2.7 Knowledge of the process for conducting special or infrequent tests.
Justification:
A. In-Correct - This SE is not considered a SICTE. This is plausible distractor since the 24 month surveillance for LOCA/LOOP testing is performed every refueling outage in accordance with an established System Engineering procedure.
B. In-Correct - This SO is not considered a SICTE. This is plausible distractor since the ESW flow surveillance is periodically performed during outages using an established Operations SurveiIlance procedure.
C. Correct - This is considered a SICTE. By definition, this test shall be a SICTE since it occurs at a specified frequency greater than one refuel cycle. Further, the containment integrated leak test is an involved complex evolution that requires the coordination of the entire station to complete.
D. In-Correct - This TP is not considered a SICTE. This is plausible distractor since the temporary SDHR system is installed and tested every refueling outage using this established Technical Procedure.
