QUESTIONS REPORT for SQN JAN 2012 NRC SRD Exam DISTRACTOR ANAL YSIS:
A. Correct, In accordance with EPM-3, at step 10 of E-0, contingency actions, the crew is directed to perform ES-0. 5, Appendix D for the conditions as stated in the stem. This is done prior to checking the Hydrogen concentration in containment.
This is acceptable since the igniters will be turned on early in the event to preclude hydrogen buildup in containment due to the ongoing steam space LOCA. (stuck open PORV). This action is to preclude a Hydrogen burn in containment that may challenge containment integrity, due to Hydrogen being released from the RCS.
Also for conditions of a LOCA with no subcooling present, the RCPs are tripped to conserve inventory in the RCS.
B. Incorrect, Plausible since the first part is correct. Also plausible since candidate could confuse the reason for tripping the RCPs with the action done for LOCAs during conditions when the RCS is in a highly voided condition, such as FR-C. 2, however as indicated in EPM-3-E-0, for small break LOCAs the RCPs are tripped to conserve inventory.
C. Incorrect, Plausible since this action was previously performed in E-1 after a LOCA had been confirmed and a transition to E-1 had been made, however it has been determined that an ice condenser plant could be susceptable to CNMT integrity challenges due to the hydrogen from the RCS being released into CNMT, thus the hydrogen igniters are to be turned on immediately upon recognizing a stuck open PZR PORV or Safety. Also the second portion is correct.
D. Incorrect, Plausible since this action was previously performed in E-1 after a LOCA had been confirmed and a transition to E-1 had been made. Also plausible since candidate could confuse the reason for tripping the RCPs with the action done for LOCAs during conditions when the RCS is in a highly voided condition, such as FR-C2, however as indicated in EPM-3-E-0, for small break LOCAs the RCPs are tripped to conserve inventory.

          -    A Reactor Trip and Safety Injection have occurred on Unit 1.
          -    All RCPs have been secured.
          -    While performing actions of E-1, Loss of Reactor or Secondary Coolant, a transition to FR-C.1, Inadequate Core Cooling, has been made.
          -    The crew has just completed depressurizing the SGs to 100 psig and have isolated the Cold Leg Accumulators.
          -    Current conditions are:
                -  RVLIS Lower Range 38% and slowly lowering.
                -  Core Exit T/Cs are 820°F and slowly rising.
                -  All SG5 levels are between 25% and 39%.
Which ONE of the following describes the NEXT evolution to be performed to mitigate the cooling challenge?
A Depressurize all SGs to atmospheric pressure to allow the RHR pumps to refill the RCS.
B. Open all available PZR PORVs to depressurize the RCS to allow RHR pumps to refill the RCS.
C. Immediately start one RCP in an available loop to force two-phase flow through the SG without first establishing support conditions.
D. Establish support conditions and then start one RCP in an available loop to force two-phase flow through the SG to support RCS depressurization.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:
A. Correct, In accordance with FR-C. 1, after the SGs are depressurized to 100 psi to allow the CLAs to inject and with the CETCs still above 700°F the direction is to ensure the RCPs are off and then depressurize the SGs to atmospheric pressure to further reduce RCS pressure to allow the ECCS flow into the RCS and reflood the core.
B. Incorrect, Plausible since this is the action given to depressurize the RCS when you are performing the actions of FR-P. 1 to minimize the effect of PTS. The candidate could get this direction confused with the continued use of the SGs to depressurize the RCS and re-establish core cooling.
C. Incorrect, Plausible if candidate determines that since the action of injecting the CLAs were not successful then immediate action to start RCPs would be needed and followed the direction given if the CETCs are at 1200°F following the action of depressurization of the intact SGs to atmospheric pressure.
D. Incorrect, Plausible if candidate determines that since that they would need to verify the normal support conditions are needed to be established prior to starting the RCP and that RCP start would be appropriate action following isolating the CLAs.

QUESTIONS REPORT forSQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:
A. Correct, For the conditions listed, RHR would be in service and rising indications on RM-90-IOIB would indicate that a flange leak has developed which is outside of containment. This leak is also considered unidentified since it is not being contained and collected in a tank. Also, the RCS leakrate that first meets the criteria of EPIP-1 criteria 2.5 for an NOUE is 10 gpm of unidentified leakage.
B. Incorrect, Plausible if the candidate thinks that a leaking charging pump suction relief will show up as increasing counts on Aux Bldg Vent Rad monitor, however the suction reliefs discharge to the PRT which is inside CNMT. This leakage would be considered identified leakage. Also the second part is correct.
C. Incorrect, Plausible since the first part is correct. Also the second part is plausible since 25 gpm for identified leakage is the minimum EPIP-1 criteria for an NOUE; however this is the threshold value Identified leakage not unidentified.
D. Incorrect, Plausible if the candidate thinks that a leaking charging pump suction relief will show up as increasing counts on Aux Bldg Vent Rad monitor, however the suction reliefs discharge to the PRT which is inside CNMT. This leakage is considered identified leakage. Also the second part is plausible since 25 gpm indentified leakage is the minImum EPIP-1 criteria for an NOUE.

            -  Unit I is at 99% power.
            -  Diesel Generator 1 B-B is out of service for a scheduled component outage.
            -  The reactor trips, and subsequently, a loss of offsite power occurs.

            -  A fault on Shutdown Board lA-A results in the emergency supply breaker from Diesel Generator lA-A tripping.
Which of the following identifies (I) the required action(s) and (2) the basis for the action(s)?
A. (1) Transition to ECA-0 .0, Loss of All AC Power, (2) because the ECA will direct actions to establish a heat sink with the TDAFW pump.
B. (1)  Remain in FR-H.1, to recover and establish a heat sink with the TDAFW pump, (2) because restoring heat sink is the highest priority evolution in progress.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRA CTOR ANAL YSIS:
A. Incorrect, The transition to ECA-O.O is the correct action and the ECA will direct actions ensuring the TD AFW pump is in service but the reason is not because the ECA establishes the heat sink. Plausible because the transition is correct and ECA will direct actions to place the TD AFW pump in service and establish a heat sink.
B. Incorrect, Remaining is FR-H. I is not correct; a transition to ECA-O.O is required.
Plausible because other ECAs do not take precedence over the FRGs and with a RED path there is a severe challenge to the Heat Sink function that would be addressed if the required heat sink could be established with the TD AFW pump.
C. Correct, The transition to ECA-O. 0 is the correct action and the reason is because all other procedures, including FR-H. I, assume a minimum of at least one train of shutdown power is available.
D. Incorrect, Remaining is FR-H. I is not correct; a transition to ECA-0.0 is required.
Plausible because power could be restored to the lB-B board using the maintenance breaker as directed by EA-202-4 and restoring Heat Sink is critical safety function being challenged.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:
A. Incorrect, per the AR! for the alarm identified in the stem (and AOP-M.2, Loss of Control Air) if the air pressure is less than 70 psig then control air is inoperable (and it is not covered by a T/S of its own.) The ABGTS is one the systems affected by the loss of air. Thus, the Train A ABG TS must be declared Inoperable. The Train A Containment Air Isolation valve automatically closing is plausible due to it occurring at a pressure setting air on decreasing air pressure. The suspension of fuel movement is a required action in LCO -3.9.12 if no ABGTS train is operable making the distractor more plausible.
B. Incorrect, per the AR! for the alarm identified in the stem (and AOP-M.2, Loss of Control Air) if the air pressure is less than 70 psig then control air is inoperable (and it is not covered by a T/S of its own.) The ABGTS is one the systems affected by the loss of air. Thus, the Train A ABGTS must be declared Inoperable. The Train A Containment Air Isolation valve automatically closing is plausible due to it occurring at a pressure setting air on decreasing air pressure. The suspension of fuel movement is a required action in LCO -3.9.12 if no ABGTS train is operable making the distractor more plausible and the distractor also has the correct application of LCO 3.0.3 as required by LCO -3.7.8 due to being in Mode 4.
C. Incorrect, Both trains of ABGTS are Inoperable (B- tagged and A-due to low air pressure as identified in the AR! and in AOP-M.2, Loss of Control Air). Plausible if the candidate remembers that LCO-3.0.3 is identified as not being applicable in LCO 3.9.12 which is applicable due to the movement of irradiated fuel in the storage pool, but does not remember LCO 3.7.8 is also applicable due to the plant being in Mode 4. LCO 3.0.3 is applicable for not meeting 3.7.8 and not having an identified action statement that can be applied.
D. Correct, Both trains of ABGTS are Inoperable (B- tagged and A-due to low air pressure, <7Opsig, as identified in the ARI and in AOP-M.2, Loss of Control Air)
LCO 3.9.12 is applicable due to having irradiated fuel in the pit and requires the movement of irradiated fuel in the storage pool to be stopped. While not applicable for LCO 3.9.12, LCO 3.0.3 is applicable for not meeting 3.7.8 due to not having an identified action statement that can be applied.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:
A. Incorrect, Plausible because ensuring RHR is isolated first is correct and if the RCS pressure had been rising instead of lowering, the correct transition would be to E1.
Also the second part is correct.
B. Incorrect, Plausible since EPM-3-ECA-1.2 identifies a rupture or break outside containment is most probable to occur in the Low pressure RHR System piping.
With the RCS pressure dropping, the break has not been isolated and the procedure will direct a transition to ECA-1. 1. Also plausible if the candidate misses the Loss of Containment 1.3.2 due to missing the criteria of no changing CNMT parameters then they would choose an Alert based on Loss of RCS barrier.
C. Incorrect, Plausible because sequentially isolating the RHR cold leg injection paths is performed in the procedure but after the RHR suction is isolated and if the RCS pressure had been rising, the correct transition would be to E-1. Also plausible if the candidate misses the Loss of Containment 1.3.2 due to missing the criteria of no changing CNMT parameters then they would choose an Alert based on Loss of RCS barrier.
D. Correct, EPM-3-ECA-1.2 identifies a rupture or break outside containment is most probable to occur in the Low pressure RHR System piping. With the RCS pressure dropping, the break has not been isolated and the correct procedure transition would be to ECA-1. 1. Also with a LOCA is progress and no change in CNMT pressure or sump level it is a Loss of Containment Barrier 1.3.2 and with a RCS leak which results < 40&deg;F subcooling, that would be a Loss of RCS Barrier 1.2.2.
With the Loss of 2 Barriers a Site Area Emergency would be declared.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRACTOR ANAL YSIS:
A. Correct, The reactor coolant pumps are shutdown leaving the RCS cooldown to be trended by the SG pressure instruments. The data indicates the 100&deg;F! hour cooldown rate was violated at 0830 as Tcold dropped from 55 1&deg;F to 444&deg;F and since the plant is afready in Mode 3, the plant must be in Mode 5 within the next 30 hours.
B. Incorrect, Plausible because a violation of the cooldown rate did occur at 0830 and 1815 would have been the correct time if the plant had been in Mode I when 3.0.3 was entered because there would be 6 additional hours to get to Mode 3.
C. Incorrect, Plausible because the cooldown rate not being violated could be concluded if an error was made in determining the temperatures and!or time periods and also because 1215 is the correct time the plant is required to be in Mode 5 due to 3.0.3 being entered.
D. Incorrect, Plausible because the cooldown rate not being violated could be concluded if an error was made in determining the temperatures and!or time periods and also 1815 would have been the correct time required for Mode 5 if the plant had been in Mode I when 3.0.3 was entered because there would be 6 additional hours to get to Mode 3.

          -  Unit 1 is in Mode 3 with the RCS at normal operating pressure and temperature.
          -  48 hours ago, RCS Activity was determined to be 0.38 microcuries/gram DOSE EQUIVALENT 1-131.
          -  Chemistry now reports that the RCS Activity has been on a continuous slow increase and is now 0.43 microcuries/gram DOSE EQUIVALENT 1-131.
          -  The crew begins reducing RCS Tavg in accordance with a 6 hour Tech Spec Action statement.

The basis for the RCS Tavg reduction is to limit doses at the site boundary in the event of a      (2)

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:
A. Incorrect, reducing Tavg below 500&deg;F is correct but the basis is not due to a LOCA with assumed containment leakage. Plausible because the action stated js correct and a LOCA with leakage from containment could cause elevated doses at the site boundary.
B. Correct, with the activity above the 0.35 microcuries/gram limit in the Tech Spec 3.4.8 for 48 continuous hours, Tavg is required to be reduced to less than 500&deg;F within 6 hours in accordance with the Tech Spec. The T/S bases states that reducing Tavg below 500&deg;F prevents the release of activity should a steam generator tube rupture since the saturation pressure of the primary coolant is below the lift pressure of the atmospheric steam relief valves. The limit on activity is based on the resulting 2-hour doses at the site boundary not exceeding a small fraction of the 10 CFR 100 limits following a SGTR in conjunction with an assumed steady state SG tube leak of I gpm.
C. Incorrect, reducing Tavg below 350&deg;F is not correct and the basis is not due to a LOCA with assumed containment leakage. Plausible because lowering Tavg to 350&deg;F would mean changing to Mode 4 within the next 6 hours (which is a directed action in many T/S) and a LOCA with leakage from containment could cause elevated doses at the site boundary.
D. Incorrect, reducing Tavg below 350&deg;F is not correct but the basis is being to limit doses in the event of a SG TR is correct. Plausible because lowering Tavg to 350&deg;F would mean changing to Mode 4 within the next 6 hours (which is a directed action in many T/S) and the bases is to limit doses at the site boundary during SGTR accident.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRA CTOR ANAL YSIS:
A. Incorrect, Plausible if the applicant does not remember a transition point to ES-0.3 due to need for cooldown due to low CST inventory and cooldown rate limits for the procedures. Cooldown limit of 50&deg;F/hr is the maximum cooldown limit on natural circulation however, ES-0.3 allows up to 100&deg;F/hr B. Incorrect, Plausible if the applicant does not remember a transition point to ES-0.3 due to need for coo/down due to low CST inventory and coo/down rate limits for the procedures. Coo/down limit of 50 &deg;F/hr is the maximum coo/down limit on natural circulation while implementing ES-0.2, however ES-0.3 allows up to 100 &deg;F/hr.
C. Correct. The SM decision to proceed as quickly as possible due to a condition such as CST inventory requires a decisison to made about which procedure to transition to, ES-0. 3 or ES-0. 4. Given the conditions in the stem there is no reason to believe that RVLIS is not available thus a transition to ES-0.3 would be the correct transition. Also ES-0.3 limits coo/down to 100&deg;F/hr while monitoring the for a possible steam bubble in the Reactor Vessel head that may develop while cooling down.
D. Incorrect, Plausible if the applicant does remember a transition point to ES-0. 3 due to SM decision to proceed as quickly as possible due to a condition such as CST inventory. Also the candidate may get the maximum coo/down rate of the RCS confused with the maximum coo/down rate of the PZR (200&deg;F/hr) thus may think that the maximum allowed coo/down rate of the RCS during ES-0. 3 is limited to 200&deg;F/hr instead of 100&deg;F/hr.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:
A. Incorrect, Plausible because only I RHR ioop being required to be operable is correct. Also plausible if the candidate confuses the basis for RHR loops OPERABLE and in operation during Modes 5 & 6 with the requirement for Mode 4 which for the purpose of the loops is to provide decay heat removal.
B. Incorrect, Plausible because a total of two loops are required to be OPERABLE and the condition could be misinterpreted as no RCS loops operable due to RCP and SG status (Mode 3 requires minimum level in the SG to be 25%). Also the candidate could confuse the basis for RHR loops OPERABLE and in operation during Modes 5 & 6 with the requirement for Mode 4 which for the purpose of the loops is to provide decay heat removal.
C. Correct, for current conditions LCO 3.4.1.3 requires at least two of the reactor coolant and/or residual heat removal (RHR) loops to be OPERABLE. An RCS loop consists of the loop, its associated steam generator (with WR level greater than or equal to 10%), and its reactor coolant pump. Only RCS loop 4 meets the requirement. So a minimum of one RHR loop is required to be operable. With the plant In MODE 4, a single reactor coolant loop or residual heat removal (RHR) loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops be OPERABLE.
D. Incorrect, Plausible because a total of two loop are required to be operable and the condition could be misinterpreted as no RCS loop operable due to RCP and SG status (Mode 3 requires minimum level in the SG to be 25%). Also, because requiring an RHR Train to be operable because only one RCS operable loop exists is to meet single failure criteria.
43/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 REACTOR COOLANT LOOPS AND COOLANT CIRCULATION In MODE 3, two reactor coolant loops provide sufficient heat removal capability for removing core decay heat even in the event of a bank withdrawal accident; however, a single reactor coolant loop provides sufficient heat removal capacity if a bank withdrawal accident can be prevented, i.e., by opening the Reactor Trip System breakers. Single failure considerations require that two loops be OPERABLE at all times.
In MODE 4, a single reactor coolant loop or residual heat removal (RHR) loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops be OPERABLE. Thus, if the reactor coolant loops are not OPERABLE, this specification requires two RHR loops to be OPERABLE.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:
A. Incorrect. Plausible since in accordance with AOP-R.01, if the corrolated cpm/gpd is between 50 and 75 gpd then the unit is to be shutdown wihtin 24 hrs using the normal shutdown procedures. Also plausible if the candidate gets confused about which rad monitor would be used. However due to the detector sensitivity 1-RM-90-1 191s the monitor to use for leak rate monitoring during steam generator tube leak rate determinations. 1-RM-90-255A!B is a post-accident radiation monitor, and is specified in EPIP-1, Emergency Plan Classification Flowchart as the radiation monitor used for determining potential radiation releases during an event.
B. Incorrect. Plausible if the candidate gets the guidance for Ieakrates> 75 gpd confused with guidance for leaks between 50 gpd and 75 gpd. If leakrate is >75 gpd then the unit is to be less than 50% power in 1 hr. and shutdown in 2 more hours (total of 3), and also plausible since the second part is correct.
C. Correct. Per AOP-R. 01, If the corrolated cpm/gpd is between 50 and 75 gpd then the unit is to be shutdown wthtin 24 hrs using the normal shutdown procedures.
Due to the detector sensitivity 1-RM-90-1 19 is the monitor to use for leak rate monitoring during steam generator tube leak rate determinations. 1-RM-90-255A/B is a post-accident radiation monitor, and is specified in EPIP-1, Emergency Plan Classification Flowchart as the radiation monitor used for determining potential radiation releases during an event.
Plausible since the first part is correct. Also it is plausible to believe that the data provided by the trended radiation monitor, would also be qualified to use for classifying the event.
D. Incorrect. Plausible if the candidate gets the guidance for leakrates> 75 gpd confused with guidance for leaks between 50 gpd and 75 gpd. If leakrate is >75 gpd then the unit is to be less than 50% power in 1 hr. and shutdown in 2 more hours (total of 3). Also plausible if the candidate gets confused with the rad monitor used for Ieakrate determination since 1-RM-90-255A/B is a post-accident radiation monitor, and is specified in EPIP-1, Emergency Plan Classification Flowchart as the radiation monitor used for determining potential radiation releases during an event.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:
A. Correct, The isolation valves should automatically close at 69 psig. With the control header pressure and Aux Bldg control header A at the same pressure with Aux Bldg B header rising it would indicate that at least one of the isolation valves did not go closed. AOP-M02 would have the operators ensure that the 0-FCV-32-82 & 85 are closed to isolate the leak. The Aux Bldg A header pressure is less than 70 psig according to the notes in alarm response procedure the A header would be considered Inoperable. In accordance with the TIS Bases, the loss of a train of essential air is no more severe than the loss of one of the motor driven trains because the TD Pump can still supply to steam generators.
B. Incorrect, Plausible if the candidate thinks that 1-FCV-32-102 is also isolated by the AOP-M.02 for leak isolation. This valve would automatically isolate at 50 psig. Also Only the Train A is inoperable due to loss of air to the A MD driven LCVs. The T-D AFW pump can still supply 2 steam generators due to B train of air available.
C. Incorrect, Plausible since the first part of is correct. Also the candidate may get confused on whether the TD AFW train is also inoperable, however in accordance with the T/S Bases, the loss of a sincle train of essential air is no more severe than the loss of one of the motor driven trains because the TD Pump can still supply to steam generators.
D. Incorrect, Plausible if the candidate thinks that 1-FCV-32-102 is also isolated by the AOP-M.02 for leak isolation. This valve would automatically isolate at 50 psig. Also the second part is correct.

A. Incorrect, Plausible because a 50.59 review would be required if the disablement were to exceed 90 days. See OPDP-4 excerpt below.
B. Incorrect, Plausible because a Technical Evaluation would be required if the disablement caused the Inputs to the alarm to also be disabled. See OPDP-4 excerpt below.
C. Incorrect, Plausible because a 50.59 review and a Technical Evaluation would be required if the annunciator input were to be disabled with the equipment remaining in service. See OPDP-4 excerpt below.
D. Correct, In accordance with OPDP-4, Annunciator Disablement, the annunciator input can be disabled without either 50.59 or a Technical Evaluation being performed. See OPDP-4 excerpt below.
OPDP-4 Appendix A B. If an annunciator window/input is disabled in support of maintenance or surveillance activities, a 50.59 review is not required UNLESS the annunciator will remain disabled for more than 90 days. If 90 days will be exceeded, a 50.59 review shall be completed prior to exceeding 90 days. A Technical Evaluation is required prior to disablement if alarm functions will be disabled for equipment remaining in service (not removed from service/inoperable for the maintenance activity).
: 1. The following example would be considered necessary to support maintenance activities and requires a Technical Evaluation:
A pump is tagged with a clearance for maintenance. Its suction pressure switch will be depressurized and disabling the associated low pressure alarm will disable the alarm function for other equipment that must remain in service.
: 2. The following examples would be considered necessary to support maintenance activities and do not require a Technical Evaluation provided the parameter is the only input to the alarm:
A pump is tagged with a clearance for maintenance. Its suction pressure switch will be depressurized and the associated low pressure alarm disabled.
An instrument is declared inoperable, and any required LCO action(s) are entered for calibration in accordance with an approved maintenance instruction. The alarm from this instrument is disabled.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRA CTOR ANALYSIS:
A. Incorrect, 0-GO-7 states that 0-GO-15, Containment Closure Control, is to be implemented to track containment configuration changes when the unit enters Mode 5. 0-GO-15 identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration.
Denying approval is plausible because the denial is required if the ACT/ECT is negative unless the opening is approved by the Operation Manager.
B. Correct, 0-GO-7 states that 0-GO-15, Containment Closure Control, is to be implemented to track containment configuration changes when the unit enters Mode 5. 0-GO-iS identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration.
C. Incorrect, 0-GO-15 purpose statement says the GO provides the requirements for Containment Closure Control in the event of a loss of RHR shutdown cooling, making the implementation of the GO when RHR is placed in service plausible because the purpose of the procedure is to provide the requirements for Containment Closure Control in the event of loss of RHR shutdown cooling, however, the correct implementation is when the Unit enters Mode 5. 0-GO-iS identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration. Denying approval is plausible because the denial is required if the ACT/ECT is negative unless the opening is approved by the Operation Manager.
D. Incorrect, 0-GO-15 purpose statement says the GO provides the requirements for Containment Closure Control in the event of a loss of RHR shutdown cooling, making the implementation of the GO when RHR is placed in service plausible, because the purpose of the procedure is to provide the requirements for Containment Closure Control in the event of loss of RHR shutdown cooling.
However, the correct implementation is when the Unit enters Mode 5. 0-GO-IS identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration.

QUESTIONS REPORT forSQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:
A. Incorrect, Plausible, if the candidate thinks that the tech spec for minimum temperature is allowed and therefore no restrictions would apply to enter Mode 4.
Also plausible since the second part is correct.
B. Incorrect, Plausible, Plausible, if the candidate thinks that the tech spec for minimum temperature is allowed and therefore no restrictions would apply to enter Mode 4. Also plausible if the candidate thought that the design base accident for this condtion of containment temperature was steam line break.
C. Correct, Per LCO 3.6. 1.5 the minimum required lower containment air temperature for operability is 60&deg;F. LCO 3.6.1.5 is not one of the Tech Specs which are restricted from applying LCO 3.0.4.b, and therefore if these provisions are met, the mode change can be made. Also the basis for minimum lower containment air temperature is to limit the total air mass in lower containment such that if a LOCA were to occur during modes 1, 2, 3 or 4, the internal pressure of Containment would not exceed design maximum for the accident.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRA CTOR ANAL YSIS:
A. Incorrect, Plausible if applicant believes that B train Cs is necessary to prevent a release or to maintain FR-Z yellow or restore to green. However B train CS is not necessary to maintaining critical safety functions or to protect the public since A train is reducing CNMT pressure without it. Per EPM-4 Yellow paths are OPTIONAL to the operator therefore not required to maintain critical safety functions. The REP does not recognize yellow paths for REP criteria to protect public health.
B. Correct, B train CS is not necessary to maintaining critical safety functions or to protect the public. Per EPM-4 Yellow paths are OPTIONAL to the operator therefore not required to maintain critical safety functions. The REP does not recognize yellow paths for REP criteria to protect public health, thus does not meet requirement for emergency exposures to maintain critical safety functions per EPIP- 15.
C. Incorrect, Plausible if applicant believes that B train CS is necessary to prevent a release and emergency exposure limits always apply during REP to correct any situation. However per EPM-4 Yellow paths are OPTIONAL to the operator therefore not required to maintain critical safety functions. The REP does not recognize yellow paths for REP criteria to protect publlc health.
D. Incorrect. Plausible since the action is correct, however the reason is incorrect.
Also plausible because there are different restrictions depending on REP classifications and in this case there is no direct threat to public heath.

76. 008 G2.4.18 076 Given the following plant conditions:

- Unit I has just experienced a Rx Trip and SI due to a failed open PORV.

- The crew has entered E-0, Reactor Trip or Safety Injection.

- The operating crew is unable to close the PORV block valve.

- Pressurizer level indicates off-scale high.

- CCPIT Flow indicates 100 gpm.

- Containment pressure is 0.3 psig

- RCS pressure is 1150 psig and lowering.

- The SRO directs a transition to E-1, Loss of Reactor or Secondary Coolant.

Which ONE of the following completes the statement below?

The initiation of an Appendix to establish Hydrogen Mitigation Actions will first be implemented (1) and the RCPs will be tripped to (2) w Av by a step in E-0 prevent excessive depletion of RCS inventory through the break B. by a step in E-0 prevent damage to RCPs operating in a highly voided system C. by a step in E-1 prevent excessive depletion of RCS inventory through the break D. by a step in E-1 prevent damage to RCPs operating in a highly voided system Wednesday, November 23, 201111:40:48 AM 76

QUESTIONS REPORT for SQN JAN 2012 NRC SRD Exam DISTRACTOR ANAL YSIS:

A. Correct, In accordance with EPM-3, at step 10 of E-0, contingency actions, the crew is directed to perform ES-0. 5, Appendix D for the conditions as stated in the stem. This is done prior to checking the Hydrogen concentration in containment.

This is acceptable since the igniters will be turned on early in the event to preclude hydrogen buildup in containment due to the ongoing steam space LOCA. (stuck open PORV). This action is to preclude a Hydrogen burn in containment that may challenge containment integrity, due to Hydrogen being released from the RCS.

Also for conditions of a LOCA with no subcooling present, the RCPs are tripped to conserve inventory in the RCS.

B. Incorrect, Plausible since the first part is correct. Also plausible since candidate could confuse the reason for tripping the RCPs with the action done for LOCAs during conditions when the RCS is in a highly voided condition, such as FR-C. 2, however as indicated in EPM-3-E-0, for small break LOCAs the RCPs are tripped to conserve inventory.

C. Incorrect, Plausible since this action was previously performed in E-1 after a LOCA had been confirmed and a transition to E-1 had been made, however it has been determined that an ice condenser plant could be susceptable to CNMT integrity challenges due to the hydrogen from the RCS being released into CNMT, thus the hydrogen igniters are to be turned on immediately upon recognizing a stuck open PZR PORV or Safety. Also the second portion is correct.

D. Incorrect, Plausible since this action was previously performed in E-1 after a LOCA had been confirmed and a transition to E-1 had been made. Also plausible since candidate could confuse the reason for tripping the RCPs with the action done for LOCAs during conditions when the RCS is in a highly voided condition, such as FR-C2, however as indicated in EPM-3-E-0, for small break LOCAs the RCPs are tripped to conserve inventory.

77. 011 EA2.01 377 Given the following plant conditions:

- A Reactor Trip and Safety Injection have occurred on Unit 1.

- All RCPs have been secured.

- While performing actions of E-1, Loss of Reactor or Secondary Coolant, a transition to FR-C.1, Inadequate Core Cooling, has been made.

- The crew has just completed depressurizing the SGs to 100 psig and have isolated the Cold Leg Accumulators.

- Current conditions are:

- RVLIS Lower Range 38% and slowly lowering.

- Core Exit T/Cs are 820°F and slowly rising.

- All SG5 levels are between 25% and 39%.

Which ONE of the following describes the NEXT evolution to be performed to mitigate the cooling challenge?

A Depressurize all SGs to atmospheric pressure to allow the RHR pumps to refill the RCS.

B. Open all available PZR PORVs to depressurize the RCS to allow RHR pumps to refill the RCS.

C. Immediately start one RCP in an available loop to force two-phase flow through the SG without first establishing support conditions.

D. Establish support conditions and then start one RCP in an available loop to force two-phase flow through the SG to support RCS depressurization.

Wednesday, November 23, 201111:47:36 AM 77

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:

A. Correct, In accordance with FR-C. 1, after the SGs are depressurized to 100 psi to allow the CLAs to inject and with the CETCs still above 700°F the direction is to ensure the RCPs are off and then depressurize the SGs to atmospheric pressure to further reduce RCS pressure to allow the ECCS flow into the RCS and reflood the core.

B. Incorrect, Plausible since this is the action given to depressurize the RCS when you are performing the actions of FR-P. 1 to minimize the effect of PTS. The candidate could get this direction confused with the continued use of the SGs to depressurize the RCS and re-establish core cooling.

C. Incorrect, Plausible if candidate determines that since the action of injecting the CLAs were not successful then immediate action to start RCPs would be needed and followed the direction given if the CETCs are at 1200°F following the action of depressurization of the intact SGs to atmospheric pressure.

D. Incorrect, Plausible if candidate determines that since that they would need to verify the normal support conditions are needed to be established prior to starting the RCP and that RCP start would be appropriate action following isolating the CLAs.

QUESTIONS REPORT forSQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:

A. Correct, For the conditions listed, RHR would be in service and rising indications on RM-90-IOIB would indicate that a flange leak has developed which is outside of containment. This leak is also considered unidentified since it is not being contained and collected in a tank. Also, the RCS leakrate that first meets the criteria of EPIP-1 criteria 2.5 for an NOUE is 10 gpm of unidentified leakage.

B. Incorrect, Plausible if the candidate thinks that a leaking charging pump suction relief will show up as increasing counts on Aux Bldg Vent Rad monitor, however the suction reliefs discharge to the PRT which is inside CNMT. This leakage would be considered identified leakage. Also the second part is correct.

C. Incorrect, Plausible since the first part is correct. Also the second part is plausible since 25 gpm for identified leakage is the minimum EPIP-1 criteria for an NOUE; however this is the threshold value Identified leakage not unidentified.

D. Incorrect, Plausible if the candidate thinks that a leaking charging pump suction relief will show up as increasing counts on Aux Bldg Vent Rad monitor, however the suction reliefs discharge to the PRT which is inside CNMT. This leakage is considered identified leakage. Also the second part is plausible since 25 gpm indentified leakage is the minImum EPIP-1 criteria for an NOUE.

79. 056 AG2.4.18 079 Given the following plant conditions:

- Unit I is at 99% power.

- Diesel Generator 1 B-B is out of service for a scheduled component outage.

- The reactor trips, and subsequently, a loss of offsite power occurs.

- The crew transitions to FR-H.1, Loss of Secondary Heat Sink, due to a RED path, and is performing the first step.

- A fault on Shutdown Board lA-A results in the emergency supply breaker from Diesel Generator lA-A tripping.

Which of the following identifies (I) the required action(s) and (2) the basis for the action(s)?

A. (1) Transition to ECA-0 .0, Loss of All AC Power, (2) because the ECA will direct actions to establish a heat sink with the TDAFW pump.

B. (1) Remain in FR-H.1, to recover and establish a heat sink with the TDAFW pump, (2) because restoring heat sink is the highest priority evolution in progress.

C (1) Transition to ECA-0 .0, Loss of All AC Power.

(2) because all other procedures in the EOP network assume a minimum of at least one 6.9kv Shutdown Board is available.

D. (1) Remain in FR-H.1 and initiate EA-202-4, Emergency Use of 6900 v Shutdown Utility Bus, to energize Shutdown Board I B-B (2) because restoring heat sink is the highest priority evolution in progress.

Wednesday, November 23, 2011 12:20:21 PM 79

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRA CTOR ANAL YSIS:

A. Incorrect, The transition to ECA-O.O is the correct action and the ECA will direct actions ensuring the TD AFW pump is in service but the reason is not because the ECA establishes the heat sink. Plausible because the transition is correct and ECA will direct actions to place the TD AFW pump in service and establish a heat sink.

B. Incorrect, Remaining is FR-H. I is not correct; a transition to ECA-O.O is required.

Plausible because other ECAs do not take precedence over the FRGs and with a RED path there is a severe challenge to the Heat Sink function that would be addressed if the required heat sink could be established with the TD AFW pump.

C. Correct, The transition to ECA-O. 0 is the correct action and the reason is because all other procedures, including FR-H. I, assume a minimum of at least one train of shutdown power is available.

D. Incorrect, Remaining is FR-H. I is not correct; a transition to ECA-0.0 is required.

Plausible because power could be restored to the lB-B board using the maintenance breaker as directed by EA-202-4 and restoring Heat Sink is critical safety function being challenged.

Wednesday, November23, 2011 12:59:03 PM 80

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:

A. Incorrect, per the AR! for the alarm identified in the stem (and AOP-M.2, Loss of Control Air) if the air pressure is less than 70 psig then control air is inoperable (and it is not covered by a T/S of its own.) The ABGTS is one the systems affected by the loss of air. Thus, the Train A ABG TS must be declared Inoperable. The Train A Containment Air Isolation valve automatically closing is plausible due to it occurring at a pressure setting air on decreasing air pressure. The suspension of fuel movement is a required action in LCO -3.9.12 if no ABGTS train is operable making the distractor more plausible.

B. Incorrect, per the AR! for the alarm identified in the stem (and AOP-M.2, Loss of Control Air) if the air pressure is less than 70 psig then control air is inoperable (and it is not covered by a T/S of its own.) The ABGTS is one the systems affected by the loss of air. Thus, the Train A ABGTS must be declared Inoperable. The Train A Containment Air Isolation valve automatically closing is plausible due to it occurring at a pressure setting air on decreasing air pressure. The suspension of fuel movement is a required action in LCO -3.9.12 if no ABGTS train is operable making the distractor more plausible and the distractor also has the correct application of LCO 3.0.3 as required by LCO -3.7.8 due to being in Mode 4.

C. Incorrect, Both trains of ABGTS are Inoperable (B- tagged and A-due to low air pressure as identified in the AR! and in AOP-M.2, Loss of Control Air). Plausible if the candidate remembers that LCO-3.0.3 is identified as not being applicable in LCO 3.9.12 which is applicable due to the movement of irradiated fuel in the storage pool, but does not remember LCO 3.7.8 is also applicable due to the plant being in Mode 4. LCO 3.0.3 is applicable for not meeting 3.7.8 and not having an identified action statement that can be applied.

D. Correct, Both trains of ABGTS are Inoperable (B- tagged and A-due to low air pressure, <7Opsig, as identified in the ARI and in AOP-M.2, Loss of Control Air)

LCO 3.9.12 is applicable due to having irradiated fuel in the pit and requires the movement of irradiated fuel in the storage pool to be stopped. While not applicable for LCO 3.9.12, LCO 3.0.3 is applicable for not meeting 3.7.8 due to not having an identified action statement that can be applied.

81. W/E04 G2.4.6 081 Given the following plant conditions:

- The Unit 1 crew enters ECA-1 .2, LOCA Outside Containment.

- When ECA-1 .2 is complete the following conditions exist:

- CNMT pressure is 0.1 psig and stable.

- RWST level is 70% and dropping.

- RCS subcooling is 0°F.

- RCS pressure is 800 psig and dropping.

- RVLIS is 42% and slowly rising.

Which ONE of the following completes the statements below?

Upon completion of ECA-1 .2, the crew will transition to (1)

The Emergency Plan Classification for this event is a(n) (2)

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:

A. Incorrect, Plausible because ensuring RHR is isolated first is correct and if the RCS pressure had been rising instead of lowering, the correct transition would be to E1.

Also the second part is correct.

B. Incorrect, Plausible since EPM-3-ECA-1.2 identifies a rupture or break outside containment is most probable to occur in the Low pressure RHR System piping.

With the RCS pressure dropping, the break has not been isolated and the procedure will direct a transition to ECA-1. 1. Also plausible if the candidate misses the Loss of Containment 1.3.2 due to missing the criteria of no changing CNMT parameters then they would choose an Alert based on Loss of RCS barrier.

C. Incorrect, Plausible because sequentially isolating the RHR cold leg injection paths is performed in the procedure but after the RHR suction is isolated and if the RCS pressure had been rising, the correct transition would be to E-1. Also plausible if the candidate misses the Loss of Containment 1.3.2 due to missing the criteria of no changing CNMT parameters then they would choose an Alert based on Loss of RCS barrier.

D. Correct, EPM-3-ECA-1.2 identifies a rupture or break outside containment is most probable to occur in the Low pressure RHR System piping. With the RCS pressure dropping, the break has not been isolated and the correct procedure transition would be to ECA-1. 1. Also with a LOCA is progress and no change in CNMT pressure or sump level it is a Loss of Containment Barrier 1.3.2 and with a RCS leak which results < 40°F subcooling, that would be a Loss of RCS Barrier 1.2.2.

With the Loss of 2 Barriers a Site Area Emergency would be declared.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRACTOR ANAL YSIS:

A. Correct, The reactor coolant pumps are shutdown leaving the RCS cooldown to be trended by the SG pressure instruments. The data indicates the 100°F! hour cooldown rate was violated at 0830 as Tcold dropped from 55 1°F to 444°F and since the plant is afready in Mode 3, the plant must be in Mode 5 within the next 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

B. Incorrect, Plausible because a violation of the cooldown rate did occur at 0830 and 1815 would have been the correct time if the plant had been in Mode I when 3.0.3 was entered because there would be 6 additional hours to get to Mode 3.

C. Incorrect, Plausible because the cooldown rate not being violated could be concluded if an error was made in determining the temperatures and!or time periods and also because 1215 is the correct time the plant is required to be in Mode 5 due to 3.0.3 being entered.

D. Incorrect, Plausible because the cooldown rate not being violated could be concluded if an error was made in determining the temperatures and!or time periods and also 1815 would have been the correct time required for Mode 5 if the plant had been in Mode I when 3.0.3 was entered because there would be 6 additional hours to get to Mode 3.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:

A. Incorrect, reducing Tavg below 500°F is correct but the basis is not due to a LOCA with assumed containment leakage. Plausible because the action stated js correct and a LOCA with leakage from containment could cause elevated doses at the site boundary.

B. Correct, with the activity above the 0.35 microcuries/gram limit in the Tech Spec 3.4.8 for 48 continuous hours, Tavg is required to be reduced to less than 500°F within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> in accordance with the Tech Spec. The T/S bases states that reducing Tavg below 500°F prevents the release of activity should a steam generator tube rupture since the saturation pressure of the primary coolant is below the lift pressure of the atmospheric steam relief valves. The limit on activity is based on the resulting 2-hour doses at the site boundary not exceeding a small fraction of the 10 CFR 100 limits following a SGTR in conjunction with an assumed steady state SG tube leak of I gpm.

C. Incorrect, reducing Tavg below 350°F is not correct and the basis is not due to a LOCA with assumed containment leakage. Plausible because lowering Tavg to 350°F would mean changing to Mode 4 within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (which is a directed action in many T/S) and a LOCA with leakage from containment could cause elevated doses at the site boundary.

D. Incorrect, reducing Tavg below 350°F is not correct but the basis is being to limit doses in the event of a SG TR is correct. Plausible because lowering Tavg to 350°F would mean changing to Mode 4 within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (which is a directed action in many T/S) and the bases is to limit doses at the site boundary during SGTR accident.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRA CTOR ANAL YSIS:

A. Incorrect, Plausible if the applicant does not remember a transition point to ES-0.3 due to need for cooldown due to low CST inventory and cooldown rate limits for the procedures. Cooldown limit of 50°F/hr is the maximum cooldown limit on natural circulation however, ES-0.3 allows up to 100°F/hr B. Incorrect, Plausible if the applicant does not remember a transition point to ES-0.3 due to need for coo/down due to low CST inventory and coo/down rate limits for the procedures. Coo/down limit of 50 °F/hr is the maximum coo/down limit on natural circulation while implementing ES-0.2, however ES-0.3 allows up to 100 °F/hr.

C. Correct. The SM decision to proceed as quickly as possible due to a condition such as CST inventory requires a decisison to made about which procedure to transition to, ES-0. 3 or ES-0. 4. Given the conditions in the stem there is no reason to believe that RVLIS is not available thus a transition to ES-0.3 would be the correct transition. Also ES-0.3 limits coo/down to 100°F/hr while monitoring the for a possible steam bubble in the Reactor Vessel head that may develop while cooling down.

D. Incorrect, Plausible if the applicant does remember a transition point to ES-0. 3 due to SM decision to proceed as quickly as possible due to a condition such as CST inventory. Also the candidate may get the maximum coo/down rate of the RCS confused with the maximum coo/down rate of the PZR (200°F/hr) thus may think that the maximum allowed coo/down rate of the RCS during ES-0. 3 is limited to 200°F/hr instead of 100°F/hr.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:

A. Incorrect, Plausible because only I RHR ioop being required to be operable is correct. Also plausible if the candidate confuses the basis for RHR loops OPERABLE and in operation during Modes 5 & 6 with the requirement for Mode 4 which for the purpose of the loops is to provide decay heat removal.

B. Incorrect, Plausible because a total of two loops are required to be OPERABLE and the condition could be misinterpreted as no RCS loops operable due to RCP and SG status (Mode 3 requires minimum level in the SG to be 25%). Also the candidate could confuse the basis for RHR loops OPERABLE and in operation during Modes 5 & 6 with the requirement for Mode 4 which for the purpose of the loops is to provide decay heat removal.

C. Correct, for current conditions LCO 3.4.1.3 requires at least two of the reactor coolant and/or residual heat removal (RHR) loops to be OPERABLE. An RCS loop consists of the loop, its associated steam generator (with WR level greater than or equal to 10%), and its reactor coolant pump. Only RCS loop 4 meets the requirement. So a minimum of one RHR loop is required to be operable. With the plant In MODE 4, a single reactor coolant loop or residual heat removal (RHR) loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops be OPERABLE.

D. Incorrect, Plausible because a total of two loop are required to be operable and the condition could be misinterpreted as no RCS loop operable due to RCP and SG status (Mode 3 requires minimum level in the SG to be 25%). Also, because requiring an RHR Train to be operable because only one RCS operable loop exists is to meet single failure criteria.

43/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 REACTOR COOLANT LOOPS AND COOLANT CIRCULATION In MODE 3, two reactor coolant loops provide sufficient heat removal capability for removing core decay heat even in the event of a bank withdrawal accident; however, a single reactor coolant loop provides sufficient heat removal capacity if a bank withdrawal accident can be prevented, i.e., by opening the Reactor Trip System breakers. Single failure considerations require that two loops be OPERABLE at all times.

In MODE 4, a single reactor coolant loop or residual heat removal (RHR) loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops be OPERABLE. Thus, if the reactor coolant loops are not OPERABLE, this specification requires two RHR loops to be OPERABLE.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:

A. Incorrect. Plausible since in accordance with AOP-R.01, if the corrolated cpm/gpd is between 50 and 75 gpd then the unit is to be shutdown wihtin 24 hrs using the normal shutdown procedures. Also plausible if the candidate gets confused about which rad monitor would be used. However due to the detector sensitivity 1-RM-90-1 191s the monitor to use for leak rate monitoring during steam generator tube leak rate determinations. 1-RM-90-255A!B is a post-accident radiation monitor, and is specified in EPIP-1, Emergency Plan Classification Flowchart as the radiation monitor used for determining potential radiation releases during an event.

B. Incorrect. Plausible if the candidate gets the guidance for Ieakrates> 75 gpd confused with guidance for leaks between 50 gpd and 75 gpd. If leakrate is >75 gpd then the unit is to be less than 50% power in 1 hr. and shutdown in 2 more hours (total of 3), and also plausible since the second part is correct.

C. Correct. Per AOP-R. 01, If the corrolated cpm/gpd is between 50 and 75 gpd then the unit is to be shutdown wthtin 24 hrs using the normal shutdown procedures.

Due to the detector sensitivity 1-RM-90-1 19 is the monitor to use for leak rate monitoring during steam generator tube leak rate determinations. 1-RM-90-255A/B is a post-accident radiation monitor, and is specified in EPIP-1, Emergency Plan Classification Flowchart as the radiation monitor used for determining potential radiation releases during an event.

Plausible since the first part is correct. Also it is plausible to believe that the data provided by the trended radiation monitor, would also be qualified to use for classifying the event.

D. Incorrect. Plausible if the candidate gets the guidance for leakrates> 75 gpd confused with guidance for leaks between 50 gpd and 75 gpd. If leakrate is >75 gpd then the unit is to be less than 50% power in 1 hr. and shutdown in 2 more hours (total of 3). Also plausible if the candidate gets confused with the rad monitor used for Ieakrate determination since 1-RM-90-255A/B is a post-accident radiation monitor, and is specified in EPIP-1, Emergency Plan Classification Flowchart as the radiation monitor used for determining potential radiation releases during an event.

Sunday, November 27, 2011 10:38:47 AM 93

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRACTOR ANALYSIS:

A. Correct, The isolation valves should automatically close at 69 psig. With the control header pressure and Aux Bldg control header A at the same pressure with Aux Bldg B header rising it would indicate that at least one of the isolation valves did not go closed. AOP-M02 would have the operators ensure that the 0-FCV-32-82 & 85 are closed to isolate the leak. The Aux Bldg A header pressure is less than 70 psig according to the notes in alarm response procedure the A header would be considered Inoperable. In accordance with the TIS Bases, the loss of a train of essential air is no more severe than the loss of one of the motor driven trains because the TD Pump can still supply to steam generators.

B. Incorrect, Plausible if the candidate thinks that 1-FCV-32-102 is also isolated by the AOP-M.02 for leak isolation. This valve would automatically isolate at 50 psig. Also Only the Train A is inoperable due to loss of air to the A MD driven LCVs. The T-D AFW pump can still supply 2 steam generators due to B train of air available.

C. Incorrect, Plausible since the first part of is correct. Also the candidate may get confused on whether the TD AFW train is also inoperable, however in accordance with the T/S Bases, the loss of a sincle train of essential air is no more severe than the loss of one of the motor driven trains because the TD Pump can still supply to steam generators.

D. Incorrect, Plausible if the candidate thinks that 1-FCV-32-102 is also isolated by the AOP-M.02 for leak isolation. This valve would automatically isolate at 50 psig. Also the second part is correct.

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRA CTOR ANAL YSIS:

A. Incorrect, Plausible because a 50.59 review would be required if the disablement were to exceed 90 days. See OPDP-4 excerpt below.

B. Incorrect, Plausible because a Technical Evaluation would be required if the disablement caused the Inputs to the alarm to also be disabled. See OPDP-4 excerpt below.

C. Incorrect, Plausible because a 50.59 review and a Technical Evaluation would be required if the annunciator input were to be disabled with the equipment remaining in service. See OPDP-4 excerpt below.

D. Correct, In accordance with OPDP-4, Annunciator Disablement, the annunciator input can be disabled without either 50.59 or a Technical Evaluation being performed. See OPDP-4 excerpt below.

OPDP-4 Appendix A B. If an annunciator window/input is disabled in support of maintenance or surveillance activities, a 50.59 review is not required UNLESS the annunciator will remain disabled for more than 90 days. If 90 days will be exceeded, a 50.59 review shall be completed prior to exceeding 90 days. A Technical Evaluation is required prior to disablement if alarm functions will be disabled for equipment remaining in service (not removed from service/inoperable for the maintenance activity).

1. The following example would be considered necessary to support maintenance activities and requires a Technical Evaluation:

A pump is tagged with a clearance for maintenance. Its suction pressure switch will be depressurized and disabling the associated low pressure alarm will disable the alarm function for other equipment that must remain in service.

2. The following examples would be considered necessary to support maintenance activities and do not require a Technical Evaluation provided the parameter is the only input to the alarm:

A pump is tagged with a clearance for maintenance. Its suction pressure switch will be depressurized and the associated low pressure alarm disabled.

An instrument is declared inoperable, and any required LCO action(s) are entered for calibration in accordance with an approved maintenance instruction. The alarm from this instrument is disabled.

A. When Unit enters Approval granted to open the Mode 5 penetration without restrictions B When Unit enters Require person to close penetration Mode 5 to be stationed at the penetration C. When RHR is placed Approval granted to open the in service penetration without restrictions D. When RHR is placed Require person to close penetration in service to be stationed at the penetration Sunday, November 27, 201111:08:59 AM 95

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRA CTOR ANALYSIS:

A. Incorrect, 0-GO-7 states that 0-GO-15, Containment Closure Control, is to be implemented to track containment configuration changes when the unit enters Mode 5. 0-GO-15 identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration.

Denying approval is plausible because the denial is required if the ACT/ECT is negative unless the opening is approved by the Operation Manager.

B. Correct, 0-GO-7 states that 0-GO-15, Containment Closure Control, is to be implemented to track containment configuration changes when the unit enters Mode 5. 0-GO-iS identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration.

C. Incorrect, 0-GO-15 purpose statement says the GO provides the requirements for Containment Closure Control in the event of a loss of RHR shutdown cooling, making the implementation of the GO when RHR is placed in service plausible because the purpose of the procedure is to provide the requirements for Containment Closure Control in the event of loss of RHR shutdown cooling, however, the correct implementation is when the Unit enters Mode 5. 0-GO-iS identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration. Denying approval is plausible because the denial is required if the ACT/ECT is negative unless the opening is approved by the Operation Manager.

D. Incorrect, 0-GO-15 purpose statement says the GO provides the requirements for Containment Closure Control in the event of a loss of RHR shutdown cooling, making the implementation of the GO when RHR is placed in service plausible, because the purpose of the procedure is to provide the requirements for Containment Closure Control in the event of loss of RHR shutdown cooling.

However, the correct implementation is when the Unit enters Mode 5. 0-GO-IS identifies that if the margin is less than 15 minutes, the persons having responsibility for closure are required to be stationed at the penetration.

Sunday, November 27, 201111:37:03 AM 96

QUESTIONS REPORT forSQN JAN 2012 NRC SRO Exam DISTRACTOR ANAL YSIS:

A. Incorrect, Plausible, if the candidate thinks that the tech spec for minimum temperature is allowed and therefore no restrictions would apply to enter Mode 4.

Also plausible since the second part is correct.

B. Incorrect, Plausible, Plausible, if the candidate thinks that the tech spec for minimum temperature is allowed and therefore no restrictions would apply to enter Mode 4. Also plausible if the candidate thought that the design base accident for this condtion of containment temperature was steam line break.

C. Correct, Per LCO 3.6. 1.5 the minimum required lower containment air temperature for operability is 60°F. LCO 3.6.1.5 is not one of the Tech Specs which are restricted from applying LCO 3.0.4.b, and therefore if these provisions are met, the mode change can be made. Also the basis for minimum lower containment air temperature is to limit the total air mass in lower containment such that if a LOCA were to occur during modes 1, 2, 3 or 4, the internal pressure of Containment would not exceed design maximum for the accident.

D. Incorrect, Plausible, since the first part is correct, and also plausible if the candidate thought that the design base accident for this condtion of containment temperature was steam line break Sunday, November 27, 201111:37:03 AM 97

- A LOCA occurred on Unit 1.

- A Site Area Emergency has been declared.

- The Containment Barrier is intact (i.e. no loss or potential loss of containment).

- The Containment Critical Safety Function Status Tree (FR-Z) is Yellow due to high radiation in containment.

- Containment pressure is 2.1 psig and decreasing.

- There is no release to the environment in progress.

- The A train of containment spray is operating normally for plant conditions.

- The B containment spray pump tripped, 25 minutes ago, after pump amps were observed to be oscillating.

- Authorization has been given for an emergency responder to receive an emergency exposure of 11 Rem TEDE in order to restore B train containment spray.

Which one of the following completes the statement below?

The decision (1) the requirements of EPIP-1 5, Emergency Exposure Guidelines, because (2)

A. met emergency exposure is necessary to maintain critical safety functions B violated emergency exposure is NOT necessary to maintain critical safety functions C. met emergency exposure limits apply during any REP classification D. violated emergency exposure limits only apply during a General Emergency Sunday, November27, 2011 12:04:17 PM 97

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DISTRA CTOR ANAL YSIS:

A. Incorrect, Plausible if applicant believes that B train Cs is necessary to prevent a release or to maintain FR-Z yellow or restore to green. However B train CS is not necessary to maintaining critical safety functions or to protect the public since A train is reducing CNMT pressure without it. Per EPM-4 Yellow paths are OPTIONAL to the operator therefore not required to maintain critical safety functions. The REP does not recognize yellow paths for REP criteria to protect public health.

B. Correct, B train CS is not necessary to maintaining critical safety functions or to protect the public. Per EPM-4 Yellow paths are OPTIONAL to the operator therefore not required to maintain critical safety functions. The REP does not recognize yellow paths for REP criteria to protect public health, thus does not meet requirement for emergency exposures to maintain critical safety functions per EPIP- 15.

C. Incorrect, Plausible if applicant believes that B train CS is necessary to prevent a release and emergency exposure limits always apply during REP to correct any situation. However per EPM-4 Yellow paths are OPTIONAL to the operator therefore not required to maintain critical safety functions. The REP does not recognize yellow paths for REP criteria to protect publlc health.

D. Incorrect. Plausible since the action is correct, however the reason is incorrect.

Also plausible because there are different restrictions depending on REP classifications and in this case there is no direct threat to public heath.

Which ONE of the following completes the statements below?

The dive (1) the requirements of NPG-SPP-07.3, Work Activity Risk Management Process, to be classified as a HIGH risk activity If the rad level in the area of the dive is estimated at 62 Rad/hr, in accordance with RCI-14, Radiation Work Permit (RWP) Program, the RWP would be required to be approved by (2)

A. meets Radiation Protection Manager only meets Radiation Protection Manager and Plant Manager C. does NOT meet Radiation Protection Manager only D. does NOT meet Radiation Protection Manager and Plant Manager Sunday, November27, 2011 12:24:25 PM 98

QUESTIONS REPORT for SQN JAN 2012 NRC SRO Exam DIS TRACTOR ANAL YSIS:

A. Incorrect, Plausible, because the diving operation being a HIGH risk activity is correct and for values of < 50 rad/hr the Radiation Protection manager would be the only approval that is required.

B. Correct, NPG -SPP-07.3, Work Activity Risk Management Process, Attachment 2 Initial Risk Characterization identifies that All activities associated with Diving Operations, due to industry operating experience are to be characterized as HIGH and RCI-14, RADIATION WORK PERMIT (RWP) PROGRAM identifies The Plant Manager and Radiation Protection Manager must approve in writing entries into areas where whole body dose rates are = 50 Rad/hour.

C. Incorrect, Plausible, because the applicant may recall the criteria on the Site High Focus Risk and Attachment 5 PWR Operational Risk Review sheet (RED SHEET) and identify that diving is not on the sheet and for values of < 50 rad/hr the Radiation Protection manager would be the only approval that is required.

0. Incorrect, Plausible, because the applicant may recall the criteria on the Site High Focus Risk and Attachment 5 PWR Operational Risk Review sheet (RED SHEET) and identify that diving is not on the sheet. Also plausible because the Plant Manager and Radiation Protection manager being required to approve in writing entries into areas where whole body dose rates are = 50 Rad/hour is correct.

QUESTIONS REPORT forSQN JAN 2012 NRC SRO Exam DISTRA CTOR ANAL YSIS:

A. Incorrect, Plausible because the declaration of an ALERT is correct. Also plausible since most automatic functions are disabled when the components transfer switch is in the AUX position however the PZR B/U heaters can be operated either manually or in automatic.

B. Correct, Because control was established within the 15 minutes, the required declaration is an ALERT and after 6.9kV Shutdown Board equipment has been configured per Attach 4, the Pressurizer Backup Heaters IA-A can be operated in either automatic or manual from the control on the breaker door.

C. Incorrect, Plausible because the declaration of an SAE would be correct if candidate thought that control had not been established within the 15 minute allowance and needed to wait for the report from the AUO that Attach 4 had been completed. Also plausibe since most automatic functions are disabled when the components transfer switch is in the AUX position.

D. Plausible because the declaration of an SAE would be correct if candidate thought that control had not been established within the 15 minute allowance and needed to wait for the report from the AUO that Attach 4 had been completed. Also the heaters having both manual and automatic control after the transfer switch is in the AUX position is correct.
