1/2008 Sequoyah SRO NRC Exam 0210812008

1. Given the following plant conditions:

- Unit 1 tripped from 10% power due to trip of both MFPTs.

- The AFW pumps start signal was generated from the trip of both MFPTs.

- Steam generator levels dropped to 12% (Lowest Level) post trip, and are slowly rising.

Which. ONE (1) of the following describes the operator response to enable the operator to MANUALLY control AFW flow?

A':I MO AFW LCVs must be taken to Accident Reset before the valves can be controlled manually.

NO reset is required to control TO AFW LCVs manually.

B. TO AFW Pump must be taken to Accident Reset before the associated AFW flow can be controlled manually.

NO reset is required to control MO AFW LCVs manually.

C. Both the TO AFW Pump and the MO AFW LCVs must be taken to Accident Reset before AFW flow can be controlled.

O. Neither the TO AFW Pump nor the MO AFW LCVs must be taken to Accident Reset before AFW flow can be controlled.

Page 1

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Correct; The MO pump LCVs must be reset and while the TO AFW pump must be reset in order to control the speed of the turbine, the LCVs require no reset action.

B. Incorrect; The TO LCVs do not require the accident reset and the MO AFW LCVs do require the reset. Plausible because the candidate could confuse the TO AFW pump reset action required with the MO AFW LCVs.

C. Incorrect; The TO LCVs do not require the accident reset and the MO AFW LCVs do require the reset. Plausible because the candidate could correctly determine that the start from the trip of both MFP is an accident signal that requires the reset, but confuse the reset of the TO AFW speed control with the reset of the valves and conclude that both had to be reset.

O. Incorrect; The TO LCVs do not require the accident reset and the MO AFW LCVs do require the reset. Plausible because the candidate could think that since the low level start signal was not reached no accident signal was generated and conclude that neither would not have to be reset.

2. Given the following:

Unit 1 Reactor Trip ISafety Injection initiated due to a pressurizer relief valve being stuck partially open.

Reactor Coolant Pumps have been stopped.

Pressurizer level is 60% and slowly rising.

RCS pressure is 1310 psig and stable.

Core Exit Thermocouple temperature is 580°F.

What would be the effect on Reactor Vessel Level and Pressurizer Level if the RCS pressure is lowered due to increased pressurizer relief valve leakage?

Reactor Vessel Pressurizer Level Level A. Rising Continue to rise at the same rate B. Rising Rising faster C. Dropping Continue to rise at the same rate D~ Dropping Rising faster Page 4

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, with the RCS pressure and temperature given at saturation, a steam bubble would be formed in the reactor head if RCS pressure were lowered. This would cause the water level in the vessel to drop instead of rise as stated in the distractor and the pressurizer level to rise at a faster rate due to the expansion of the steam void forcing water into the pressurizer. Plausible if student does not recognize saturated conditions in RCS and effect of bubble growth on Pressurizer level.

B. Incorrect, with the RCS pressure and temperature given at saturation, a steam bubble would be formed in the reactor head if RCS pressure were lowered. This would cause the water level in the vessel to drop instead of rise as stated in the distractor. Plausible if student does not recognize saturated conditions in ReS and effect of bubble growth on Pressurizer level.

C. Incorrect, with the RCS pressure and temperature given at saturation, a steam bubble would be formed in the reactor head if RCS pressure were lowered. This would cause the water level in the vessel to drop as stated in the distractor. However the response of the pressurizer would be to rise at a faster rate due to the expansion of the steam void forcing water into the pressurizer. Plausible if student does recognize void formation in head and does not know effect of bubble growth on Pressurizer level.

D. Correct, with the RCS pressure and temperature given at saturation, a steam bubble would be formed in the reactor head if RCS pressure were lowered. This would cause the water level in the vessel to drop as stated in the answer and the pressurizer level to rise at eiester rate due to the expansion of the steam void forcing water into the pressurizer.

3. Unit 1 Reactor has been tripped with plant status as follows:

RCS pressure is 1325 psig and slowly dropping.

RCS temperature is 530°F and stable.

Pressurizer level is 17% and slowly dropping.

Containment pressure is 2.1 psig and slowly rising.

SG pressures are - 1005 psig and stable.

SG levels are - 40% and stable.

- Annunciator TS-62-43 REAC COOL PMPS SEAL WATER TEMP HIGH is LIT and indicator for RCP #3 reads 227°F and steady.

- Annunciator TS-62-42 REAC COOL PMPS LOWER BEARING TEMP HIGH is lit and indicator for RCP #1 reads 201°F and steady.

Which ONE (1) of the following is the correct action for the RCP(s) in these conditions?

A. All RCPs are required to be tripped.

B. ONLY RCP #1 is required to be tripped.

C~ ONLY RCP #3 is required to be tripped.

D. ONLY RCPs #1 and #3 are required to be tripped.

A. Incorrect. RCPs trip criteria is 1250 psig and the pressure is above the setpoint.

Plausible because there is a low pressure trip criteria that has not been reached.

B. Incorrect. Reps trip criteria is when Phase B actuates at 2.81 psig and the pressure is below the Phase B setpoint. Plausible because there is a high-high containment pressure trip that if the setpoint is reached would require tripping the RCPs.

C. Correct. RCP seal condition requiring trip is 225 0F, and the stated seal temperature is above this value.

D. Incorrect. The RCP Lower Bearing temperature is below the temperature(2250F) requiring the RCP to be tripped. Plausible because there is a setpoint for the Lower Bearing temperature requiring the affect RCP be tripped. Additionally, the Lower Motor bearing temperature trip setpoint is 200 0F and the lower pump bearing temperature could be confused with the lower motor bearing.

4. E-1, Loss of Reactor or Secondary Coolant, directs the operator to perform a transfer to Hot Leg Recirculation.

Which ONE (1) of the following statements correctly describes the basis for this realignment?

A. Realigns the ECCS flow to reduce Core Exit Thermocouple temperature to acceptable values.

B. Realigns the ECCS flow to cool the reactor vessel upper internals package.

C. Realigns the ECCS flow to pass through the RHR heat exchangers to remove decay heat.

D~ Realigns the ECCS flow to prevent boron precipitation.

A. Incorrect; Plausible due to Hot leg cooling will put cool water to the region of the GETs thus cooling the GETs however this is not the basis for doing so.

B. Incorrect; The transfer to hot leg recirc does put flow on top of the core but not to cool the upper internals. Plausible due to aligning the flow to the core outlet and reversing flow the knowledge of known flowpaths in core specific to cooling upper internals.

G. Incorrect; While the GGP and SIP EGGS flow when supplied from the RWST does not go through any heat exchanger, the RHR flow is always aligned through the RHR heat exchangers and when the transfer to the containment sump is initiated the cooling flow is placed on the RHR heat exchangers to cool the water coming from the containment sump. Plausible if confused in the alignment of the cooling flow, with the alignment of flow through the RHR heat exchangers.

D. Gorrect; EPM-3-E-1 states EGGS flow is realigned to reverse flow through the core to address the consequences of boron stratification/plate out.

5. Unit ,1 is operating at full power. Given the following events and conditions on the RCPs:

Alarms indicate a loss of ALL CCS flow to the RCPs.

Seal injection flow rate to each RCP is 8 gpm.

Which ONE (1) of the following identifies how the operation of the RCP's will be affected if the operators do not respond to this alarm?

A. The RCPs should operate without CCS indefinitely.

B. The RCPs will experience seal failure, C. The RCP stator windings will overheat.

D~ The RCP motor bearings will overheat.

A. Incorrect, the RCPs cannot operate without component cooling water because the motor bearings will overheat. Plausible to conclude that due to the seal injection flow, the loss of thermal barrier cooling would not be an issue.

B. Incorrect, The RCPs will NOT experience seal failure as long as seal injection flow is present, but plausible because seal damage would occur if the CCS were lost and seal flow was not present.

C. Incorrect, The RCP stator windings are not cooling by CCS. The motor coolers use ERCW to cool the air leaving the RCP motors. Plausible if the RCP motor cooling is confused with the RCP motor bearing cooling.

D. Correct, Loss of cooling to the motor bearings will ceuse overheating of the motor bearings and damage to the RCP motor.

6. Given the following plant conditions:

Reactor power is steady-state at 75%.

Pressurizer Level Control Selector Switch (XS-68-339E) is in the 339/335 position, and level control is in automatic.

Temperature input to the pressurizer level control system fails to 530°F.

Which ONE (1) of the following describes the effect this condition would have on the pressurizer level control system? (Assume NO operator action)

A. Charging initially increases to 120 gpm then returns to normal and pressurizer level stabilizes at a higher value.

B~ Charging initially decreases to minimum flow and indicated pressurizer level lowers to 25°~ where it stabilizes.

C. Charging decreases to minimum and indicated pressurizer level lowers to 17%,

then level rises to the high level reactor trip setpoint.

D. Charging increases to 120 gpm and the pressurizer level rises to the high level reactor trip setpoint.

Page 13

1/2008 Sequoyah SRO NRC Exam 02/08/2008 The controller uses Tavg as the input for for level setpoint. The programed level ramps from 24. 7 to 60 % as Tavg changes from 547-578 degrees F . If the controller setpoint input (Tavg) failed to a value of 530 degrees F, then the controller would sense the level as high and start reducing the charging flow to lower level. The controller has a minimum cap at 24. 7% which is where level would be at 547 degrees F.

A. Incorrect, Charging would not increase (as explained above) Plausible if candidate confuses which way the charging flow would be affected by the failure and/or because other failures would cause charging flow to increase.

Level setpoint failing high would result in this scenario.

B. Correct, the temperature input failure results in the pressurizer level setpoint to drop to 24.7%. The initial level would be 60%, therefore the control system would decrease charging to lower the level from 60% to the 24.7%

setpoint.

C. Incorrect, Level would stabilize at 24. 7% as explained in above. Plausible because other failures would cause level to drop until letdown isolates at 17%, then pressurizer refills and trip on High level occurs. Controlling channel failing high would result in this scenario.

D. Incorrect, charging does not increase as explained in 'B' above. Plausible because other failures would cause level to increase until pressurizer fills and trip on High level occurs. Controlling channel failing low would result in this scenario.

7. Unit 1 at 100 % power. All conditions are normal with the following exceptions:

07:00, 1A RHR Pump is tagged due to motor repair and will be returned to service in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

08:00, Unit 1 has a reactor trip and SI due to a LOCA.

08:01, E-O, Reactor Trip or Safety Injection, is entered followed by a transition to E-1, Loss of Reactor or Secondary Coolant.

08:08, The 1B RHR Pump trips on overcurrent due to a locked rotor.

08:14, Step 15 of E-1, transitions crew to ECA-1.1, Loss of RHR Sump Recirculation. The conditions at the transition are:

• RCS pressure is 160 psig

• Containment pressure is 9.7 psid and stable

• RWST level is 580/0 and dropping

• Containment sump level is 25% and rising Assuming the plant condition remain unchanged, and ALL ECA-1.1 steps to address Containment Spray Pump operation are completed, how many containment spray pumps will be running and what will be the suction source to the pumps?

Number of Pumps Running Suction Source A. 1 RWST B. 1 Containment sump C. 2 RWST D~ 2 Containment sump Page 16

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, Due to the requirements of ECA-1.1, with containment pressure greater than 9.5 psid but less than 12.0 psid, one of the two containment spray pump should be shutdown but with stated containment sump level, the suction would be transferred to the containment sump and both pumps placed in service. Suction would not be from the RWST. Plausible because the suction path would not be swapped to the sumps in ECA-1.1 and only 1 pump would be running with conditions other than stated in the stem.

B. Incorrect. Due to the requirements of ECA-1.1, with containment pressure greater than 9.5 psid but less than 12.0 psid, one of the two containment spray pump-should be shutdown but with stated containment sump level, the suction would be transferred to the containment sump and both pumps placed inservice. Plausible because only one pump would be running with conditions other than stated in the stem and candidate may not relate placing the stopped pump back in service when the the suctionpetri is swapped to the sumps in ECA-1.1 .

C. Incorrect. Due to the requirements of ECA-1.1, containment pressure would have to be greater than 12.0 psid to require 2 containment spray pumps to be running and aligned to the RWST. The conditions stated in the stem would result in one of the pumps being stopped, then with the level stated in the conieinment sump, the suction swapped to the containment sump and and both pumps placed back in service. Plausible if candidate is not aware relationship between containment pressure and the number of pumps that should be in service or is not aware of the sump level required to swap the suction to the sump.

D. Correct, 2 containment spray pumps would be running and the suction path would be swapped to the sump in ECA-1.1 with the conditions stated in the stem.

8. Following a total loss of all AC power, the operator is directed to isolate CCS to the RCP thermal barriers per ECA-O.O, "Loss of Shutdown Power". When offsite power is restored, the operator is directed in ECA-0.1, "Recovery from Loss of Shutdown Power without SI Required", to ensure that the RCP thermal barrier isolation is complete prior to restarting a CCS pump.

Which ONE (1) of the following describes the basis, for isolating the CCS thermal barrier return prior to restarting the CCS pump?

A. To prevent thermal shock to the RCP pump impeller upon restart of the CCS system during recovery.

B. To prevent thermal shock to the RCP seal packages upon restart of the CCS system during recovery.

C. To ensure elevated heat loads as a result of the loss of all AC power are within the design cooling capacity of CCS prior to starting a CCS pump.

D~ To prevent steam from forming and circulating in the CCS system and ensures the CCS system is available to cool equipment necessary for recovery.

A. Incorrect, Plausible due to the seal package does allow for cooling the pump shaft, however it is not the reason.

B. Incorrect, Plausible due to Isolating the thermal barrier does secure cooling flow to the seal packages, however it is not the reason.

c. Incorrect, Plausible due to Isolating the thermal barrier would reduce the heat load on the CCS but the isolation is not to ensure the loads are within the capacity of the CCS system.

D. Correct, To prevent steam from forming and circulating in the CCS system and ensures the CCS system is available to cool equipment necessary for recovery.

9. Given the following:

Reactor at 85% RTP stable conditions for 10 days.

- Both Pressurizer Spray Valve Controllers in MANUAL and output set to "0".

- All other systems and controllers in normal alignment.

Which ONE (1) of the following would be the immediate effect if the Pressurizer Master Pressure Controller was placed in MANUAL and the output is raised to 100 0/0?

A. Pressurizer Pressure HI alarm, and Actual pressurizer pressure starts to rise.

B~ Pressurizer Pressure HI alarm, and Actual pressurizer pressure starts to drop.

C. Pressurizer Pressure La alarm, and Actual pressurizer pressure starts to rise.

D. Pressurizer Pressure La alarm, and Actual pressurizer pressure starts to drop.

A. Incorrect, The Hi pressure alarm is actuated. Heaters do not energize but plausible if they did the pressure would start to rise and high pressure alarm could come in because the spray valves are in manual and will not open.

B. Correct, The Hi pressure alarm is actuated by the output of the controller as the output is increased, variable heaters all deenergize, with NO heaters the pressurizer pressure will start to drop due to ambient losses and pressurizer spray bypass flow.

C. Incorrect, low pressure alarm comes from the output of the controller dropping and the controller output is being raised to 100%, Heaters do not energize (but if they did the pressure would rise). Plausible to conclude that raising controller output could result in raising pressure.

D. Incorrect, low pressure alarm comes from the output of the controller dropping and the controller output is being raised to 100%, Heaters do deenergize and the pressure does drop. Plausible to conclude that the heater would deenergize causing pressure to lower and the low pressure alarm to come in.

Page 23

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Correct, Per OPDP-1, Operations personnel performing shift turnover will not be involved in plant evolutions/activities during performance on shift turnover activities. The Cooldown should be complete prior to conducting turnover. The OPDP also requires a log review and a control board walkdown as a part of turnover.

B. Incorrect, The cooldown should be completed prior to turnover, there is no provision for not completing the board walkdown. Plausible due to candidate could think that due to being in an emergency the walkdown would not be required.

c. Incorrect, Plausible due to candidate not knowing requirement that personnel will not be involved in activities during turnover, and candidate could think that since the cooldown should not be delayed that turnover could be conducted in parallel.

D. Incorrect, Plausible due to candidate not knowing requirement that personnel will not be involved in activities during turnover, and candidate could think that since the cooldown should not be delayed that turnover could be conducted in parallel and that due to being in an emergency the walkdown' would not be required Page 24

12. Given the following Unit 1 plant conditions:

ECA-O.O, Loss of All AC Power is in effect.

Depressurization of all intact SGs is in progress.

- The SG are to be depressurized at the "maximum rate".

Which ONE of the following identifies the parameter used to determine the maximum rate and the basis for the parameter being the limiting parameter?

A. Ability to maintain pressurizer level above 100/0 to prevent loss of pressure control resulting in reactor vessel head voiding.

B~ Ability to maintain at least one SG narrow range level above 100/0 to prevent loss of sufficient heat transfer capability from the RCS.

C. Ability to maintain RCS Tcold cooldown equal to or less than 100°F/hour to prevent transition to FR-P.1, Pressurized Thermal Shock.

D. Ability to maintain RCS pressure equal to or greater than 200 psig to prevent nitrogen from entering the the RCS from CLAs.

Page 29

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect. The ability to maintain 1 SG level above 10% narrow range is the parameter. Loss of pressurizer level and reactor vessel head voiding may occur and are acceptable during the depressurization may stated in a note preceeding step to depressurize the SGs.Maintaining pressurizer level 10% or greater is a parameter monotored in the EOPs that results in actions being taken.

B. Correct. The ability to maintain 1 SG level above 10% narrow range is the parameter and the basis is to prevent the loss of sufficient heat transfer capability from the RCS.

c. Incorrect. The ability to maintain 1 SG level above 10% narrow range is the parameter, NOT the Tcold cooldown rate. PTS is avoided by stopping the cooldown before reaching PTS temperatures and the FRGs are suspended during ECA-O.O implementation.

D. Incorrect. The ability to maintain 1 SG level above 10% narrow range is the parameter. The depressurization would be stopped and the RCS pressure controlled between 100 and 200 psig. If the pressure were to drop to below 100 psig prior to isolating CLAs, nitrogen could be injected into the RCS as described in a Caution prior to the step for depressurizingthe SGs.

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect; Plausible if student remembers that the initial strategy of ECA-1.2 is to Ensure RHR suction isolation from the RCS but does not remember that the indication is RCS pressure increasing. Pressurizer level rising is plausible since the student could reason that it may be rising if the leak was isolated. The procedure directs the use of RCS pressure increasing as the method used to indicate the leak has been isolated.

B. Correct; The procedure directs the initial strategy of ensuring RHR suction isoietion from the RCS and the use of RCS pressure increasing as the method to indicate the leak has been isolated.

C. Incorrect; Plausible because isolation of RHR Cold Leg injection is a strategy contained in the procedure but it is not the initial mitigating strategy. Pressurizer level rising is a plausible indication since the student could reason that it may be rising if the leak was isolated. The procedure directs the use of RCS pressure increasing as the method used to indicate the leak has been isolated.

D. Incorrect; Plausible because isolation of RHR Cold Leg injection is a strategy contained in the procedure but it is not the initial mitigating strategy. The procedure directs the use of ReS pressure increasing as the method used to indicate the leak has been isolated.

18. Given the following conditions:

At 0900 the Reactor Trips due to 2 dropped rods.

At 0920 a small break LOGA occurs.

At 0950 the crew transitioned to EGA-1.1, "Loss of RHR Sump Recirculation", due to the failure of both RHR pumps.

Grew has reduced EGGS flow to 1 SIP and 1 GGP per EGA-1.1.

SI flow cannot be terminated due to lack of subcooling.

At 1030 the crew is performing EGA-1.1 Step 20 RNO to establish the minimum required EGGS flow to remove decay heat.

Which one of the following correctly describes the flow rate that meets the intent of EGA-1.1, Step 20 RNO, AND requirements of using EGGS pumps in meeting this flow rate?

REFERENCE PROVIDED A':I Establish 325 gpm EGGS flow. EGGS pumps may be started and stopped as necessary to accomplish the desired flow rate.

B. Establish 325 gpm EGGS flow. EGGS pumps are NOT permitted to be started and stopped as necessary to accomplish the desired flow rate.

G. Establish 400 gpm EGGS flow. EGGS pumps may be started and stopped as necessary to accomplish the desired flow rate.

D. Establish 400 gpm EGGS flow. EGGS pumps are NOT permitted to be started and stopped as necessary to accomplish the desired flow rate.

Page 44

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Gorrect. 0900 - 1030 (90 Min) Using EGA-1.1, curve 9, the value is approximately 325 gpm. The Basis states "the operator is then instructed to establish the minimum EGGS flow needed to match decay heat in order to further decrease EGGS pump Flow and delay RWST depletion. This value, of 325 gpm is in the acceptable region using the graph from time of trip AND meets the requirement of Minimum Flow to delay RWST depletion. The procedure states EGGS pumps may be started and stopped as necessary to accomplish the 'desired flow rate.

B. Incorrect. Gorrect flow rate wrong action. Plausible if student does not know procedure requirement to start or stop pumps as neccessary due to a LOGA. The student may think that due to a LOGA pumps must not be stopped.

G. Incorrect. Plausible due to 400 gpm meets the curve requirment however it does not meet the intent of the step which is to meet the minimum flow requirements while still meeting the curve requirments. Second part correct in EGGS pumps may be started and stopped as necessary to accomplish the desired flow rate.

D. Incorrect. Plausible due to 400 gpm meets the curve requirment however it does not meet the intent of the step which is to meet the minimum flow requirements while still meeting the curve requirments. Plausible if student does not know procedure requirement to start or stop pumps as neccessary due to a LOGA. The student may think that due to a LOGA pumps must not be stopped.

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, If the Tavg Auctioneering Unit failed low, the rod control system would see large error between Tref-Tavg causing the rods start withdrawing not inserting. However, if conditions existed that did result in the rods inserting the 'RODS IN' green light indication would be illuminated, but the light is green not red. Plausible if the candidate confuses the direction of rod movement and the color of the 'RODS IN' light with the color of the 'RODS OUT' light which is red.

B. Incorrect, If the Tavg Auctioneering Unit failed low, the rod control system would see large error between Tref-Tavg causing the rods start withdrawing not inserting. However, if conditions existed that did result in the rods inserting the 'RODS IN ' green light indication would be illuminated. Plausible because the candidate could confuse the direction of rod movement but correctly identify the color of the 'RODS IN' light being green.

C. Correct, If the Tavg Auctioneering Unit failed low, the rod control system would see a large error between Tref - Tavg causing the rods to start withdrawing. Rod withdrawal causes the 'RODS OUT' red light to be illuminated.

D. Incorrect, If the Tavg Auctioneering Unit failed low, the rod control system would see large error between Tref- Tavg causing the rods start withdrawing. The 'RODS OUT' would be illuminated but the light is red not green.

Intermediate Range N36 failed high.

Operators placed the level trip bypass switch for N36 to the bypass position.

Subsequently the Reactor trips due to Large Break LOCA.

Which ONE (1) of the following describes the operation of source range instruments to be used to monitor the Subcriticality Status Tree?

A. Source Range channel N31 and N32 are automatically reinstated when power decreases below P-10.

B. Source Range channel N31 and N32 are automatically reinstated when power decreases below P-6.

C~ Both Source Range channels, N31 and N32, must be manually reinstated when the operable Intermediate Range channel (N35) decreases below the P-6 setpoint.

D. Both Source Range channels, N31 and N32, must be manually reinstated when the operable Intermediate Range channel (N35) decreases below the P-10 setpoint.

A. Incorrect, Source range channels are not reinstated until the IRMs drop below the P-6 setpoint. With one IRM failed high the SRMs cannot automatically reinstate.

Plausible because there in a P-10 backup to ground the output of the SRMs as power increases causing the SRMs output to read zero. This backup signal is automatically removed as the P-10 clears B. Incorrect, Source range channels are normally reinstated automatically when both of the IRMs drop below the P-6 setpoint. With one IRM failed high the SRMscannot automatically reinstate. Plausible because the SRM trip can be blocked as power increases when one IRM increases above the P-6 setpoint and the candidate could confuse the 1 out of 2 requirement going up with the 2 out of 2 requirement coming down.

C. Correct, with one of the IRMs failed high, manual reinstatement of the SRM is required.

D. Incorrect, SRM are automatically reinstated when the IRM drop below the P-6 setpoint, not below the P-10 setpoint. Plausible because the candidate could mistake the 2 setpoints.

27. While performing actions of FR-Z.1, "Response to High Containment Pressure", what steps are taken to limit the peak pressure rise in containment in the event of a Main Steam Line Break in containment?

A. Start Ice Condenser Air Handling Units.

B. Dispatch personnel to open Air Return Fan breakers.

C. Throttle all AFW Flow to less than 25 gpm per Steam Generator.

D~ Isolate AFW Flow to any Steam Generator depressurizing in an uncontrolled manner.

A. Incorrect. Plausible due to concept of starting Ice Condenser Air Handling Units may help cool containment thus reducing containment pressure. Step 12 directs opening of Ice Condenser AHU Breakers so option to start Ice Condenser Air Handling Units is wrong.

B. Incorrect. Plausible due to requirement to check one containment air return fan running. Since there is a step to open the Ice Condenser AHU Breakers the student may mistake the opening on the Ice Condenser Air Handling Unit Breakers with Containment Air Return Fan breakers.

C. Incorrect. Plausible due to throttling feedwater would reduce inventory going into containment thus minimizing steam release pressure rise in containment. Step 10 (If all S/Gs faulted then control feed flow to greater than or equal to 25 gpm to each S/G to prevent dryout).

D. Correct. Step 11 Isolates feed flow to affected S/G. This step may eliminate mass and energy releases to the containment.

RCS Temp Less Than 250°F Minimize Dose in Steam Generator provided RHR is in service area C. RCS Temp Less Than 180°F Lower the corrosion rate of the ReS D~ RCS Temp Less Than 180°F Minimize Dose in Steam Generator area A. Incorrect. Plausible due to the Dissolved Oxygen Technical requirement limit not being applicable below 250 degrees and the addition of Hydrogen Peroxide occurs after RHR is in service. Since adding Hydrogen Peroxide will change ph, student may may Interpret this as affecting the corrosion rate. Corrosion rate is affected for a short time by actually raising the rate due to higher oxygen levels in RCS and ph change.

B. Incorrect. Plausible due to the Dissolved Oxygen Technical requirement limit not being applicable below 250 degrees and the addition of Hydrogen Peroxide occurs after RHR is in service. Minimizing Dose in Steam Generator area is correct per note in procedure.

C. Incorrect. Plausible due to correct temp listed but reason incorrect. Since adding Hydrogen Peroxide will change ph, student may may interpret this as affecting the corrosion rate. Corrosion rate is affected for a short time by actually raising the rate due to higher oxygen levels in RCS and ph change.

30. Given the following:

Unit 1 at 100 % power Letdown in service at 75 gpm Which ONE (1) of the following lists two conditions where BOTH would result in a decrease in the available NPSH to the CCPs?

(Evaluate each condition separately)

Condition 1 Condition 2 A. VCT Level transmitter, Loss of air to 1-FCV-62-77, 1-LT-62-130A fails Low Letdown Flow Isolation B~ VCT Level transmitter Loss of air to 1-FCV-62-93, 1-LT-62-130A fails High Charging Flow Control C. Raising setpoint on Loss of air to 1-FCV-62-118, 1-TCV-70-192, Letdown Letdown Divert to HUT LCV Heat Exchanger TCV D. Lowering setpoint on Loss of air to 1-FCV-62-79, 1-TCV-70-192, Letdown Mixed Bed High Temp Bypass Heat Exchanger TCV Page 72

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, the level transmitter failing low would result in automatic makeup to the VCT and cause the VCT pressure to rise causing an increase in NPSH to the CCP. Plausible because the candidate may not realize that the failure cause the auto make-up and how that would affect VCT pressure. Condition 2 is correct in that letdown would isolate lowering level in the VCT.

B. Correct, the level transmitter failing high would result in the divert valve opening cause the VCT pressure to drop causing an decrease in NPSH to the CCP. Loss of air to the Charging Flow Control valve will cause the valve to fail open thus raising charging flow and increasing the head loss through the piping due to higher velocity, thus lowering NPSH.

C. Incorrect, raising the setpoint on the letdown heat exchanger TCV would cause the temperature in the VCT to rise while the VCT pressure remained unchanged, thus decreasing the NPSH to the CCPs. Loss of air to the Letdown Divert to HUT LCV causes the valve to fail in the VCT position therefore not affecting VCT level or NPSH to the CCPs. Plausible because the candidate could get confused on which way the changes effect letdown or not know which way the valve fails on loss of air.

D. Incorrect, lowering the setpoint on the letdown heat exchanger TCV would cause the VCT temperature to drop, thus raising the NPSH to the ch,arging pumps. However, Loss of air to the Mixed Bed High Temp Bypass will cause the valve to fail in the bypass position and ha\(e no effect on VCT level or NPSH to the charging pump. Plausible because the candidate could get confused on which way the change of the setpoint effects letdown or the effect of the failure of the Mixed Bed High Temp Bypass valve.

- The pressurizer level control system is in Automatic Which ONE (1) of the following identifies the pressurizer level control setpoint?

D. 600/0 Page 75

1/2008 Sequoyah SRO NRC Exam 02/08/2008 Justification:

Candidate should realize that at 66% power and Tavg on program, the pressurizer level should be 66% of the pressuirzer level span added back to the Zero power level setpoint.

66%(60 - 24.7) + 24.7= 47.998 = 48%

Because Tavg determines pressurizer level, another method the candidate might choose is determine the Tavg change and then determine pressurizer level change.

Per TI-28 page 10 with reactor power 66%, Tavg should be between 567 and 568 degrees F.

Per Table in AOP-C.01 Appendix A with Rx power at 66%. Tavg should be 567.6 degrees F and pressurizer level should be 48%

If Tavg calculated using data in TI-28, Attachment 9,

% Rx power ( Full power Tavg - Zero power Tavg)+ Zero power Tavg 66% (578.2 - 547) + 547= 20.592 + 547 = 567.592 If Pressurizer level setpoint calculated using data in TI-28, Attachment 9, with Tavg change of 20.592 divided by total Tavg change from 0 to 100% power then multiplied by change in pressurizer level from 0 to 100% power and added back to the minimum pressurizer level (20.592/31.2)( 60%-24.7%) +24.7= 47.998 = 48%

A. Incorrect, Plausible if the level setpoint at zero power is multiplied by the % power instead of the change in pressurizer level (35.3) 66%(24.7) + 24.7 = 41.002 = 41%

B. Incorrect, Plausible if the change in Tavg (31.2) is used instead of the change in pressurizer level (35.3) 66%(31.2) + 24.7= 42.292% = 45%

C. Correct, 66%(60 - 24.7) + 24.7 = 47.998 = 48%

D. Incorrect, Plausible if the change in pressurizer level from 0 to 100% power is divided by the % change in power instead of multiplied.

35.3 / .66 = 53.485 = 53%

41. Which ONE (1) of the following identifies a provision of the containment ice condenser design that increases the ice condenser's ability to remove heat during a small break LOCA?

A. Melted ice is directed away from the inlet doors and toward drain lines by turning vanes.

B. One out of every two ice bays has a drain which directs melted ice away from the inlet doors. (Only half of the total have drains)

C¥' Inlet doors have proportioning springs to modulate door opening which equalizes air/steam flow through each ice bay.

D. Intermediate deck doors have proportioning springs to modulate door opening which equalizes air/steam flow through each ice bay.

A. Incorrect, Turning vanes direct air/steam flow not water drainage. Plausible if candidate confused the purpose of the turning vanes. From FSAR test results show that containment final peak pressure is not affected by drain performance.

B. Incorrect, All of the bays do not have drains but more than half does.

Plausible if the candidate believes only half of the bays have drains. From FSAR test results show that containment final peak pressure is not affected by drain performance.

c. Correct, The door panels are provided with tension spring mechanisms that produce a small closing torque on the door panels as they open. The zero load position of the spring mechanisms is set such that, with zero differential pressure across the door panels, the gasket holds the door slightly open.

This setting provides assurance that all doors will be open slightly, upon removal of cold air head, therefore eliminating significant inlet maldistribution for very small incidents.

D. Incorrect, the springs are on the inlet doors, not the intermediate doors.

Plausible because the intermediate doors do open when pressure builds up in the ice condenser bay.

43. Given the following plant conditions:

Unit 1 in service at 100 % power.

Due to the Normal feeder breaker to 6.9kV Shutdown Board 1B-B inadvertently opening, 1B-B Diesel Generator started and energized the board.

One hour later, the following occurs:

- At 1405 a steamline break occurs inside containment.

Containment pressure is 3 psig and rising.

- At 1407 the CRO observes that 1B-B Containment Spray Pump ammeter reads

'0' amps and the only light LIT above the handswitch is the GREEN light.

Which ONE (1) of the following describes the current status of the 1B-B Containment Spray Pump AND the correct operator response or reason for current status?

A. Pump should be running but has failed to auto start.

Immediately start 1B-B Containment Spray Pump after verifying sequencer has timed out.

B. Pump should be running but has failed to auto start.

Verify 1B-B DIG loading available, then start 1B-B Containment Spray Pump.

C. Pump status is currently correct.

UVX and UVY relays are preventing start of the 1B-B Containment Spray Pump.

D~ Pump status is currently correct.

Blackout timer has NOT timed out to start the 1B-B Containment Spray Pump.

Page 109

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, The Containment Spray Pump has not failed to start. It should not be running with the stated conditions. The timer to start the pump is active but has not timed out. Plausible because the 1B-B Shutdown Board experienced the blackout over an hour earlier, the student may think timer should already be timed out, which would result in the pump starting immediately when the containment pressure reached the setpoint. Starting the pump could cause a overload on the diesel generator if another pump auto started at the same time as the manual start.

B. Incorrect, the Containment Spray Pump has not failed to start. It should not be running with the stated conditions. The timer to start the pump is active but has not timed out. Plausible because the 1B-B Shutdown Board experienced the blackout over an hour earlier, the student may think timer should already be timed out, which would result in the pump starting immediately when the containment pressure reached the setpoint. Verifying DIG loading prior to starting the pump is an action taken later when adding loads to a board supplied by a diesel generator but with the conditions given the time sequencer is still loading the board. Starting the pump could cause a overload on the diesel generator if another pump auto started at the same time as the manual start.

C. Incorrect, While the Containment Spray Pump should not be running with the stated conditions, the reason is not because the UVX and UVY relays are preventing the start of the pump. These relays cause the load shedding of the pump when the board voltage is lost. After the board is reenergized these relays will allow the pump to restart when the blackout timer has timed out. The BOX and BOY relays are blocking the automatic start until the 180 second time delay elapses. The timer to start the pump is active but has not timed out. Plausible the student may know the UVX and UVY relays function during a blackout but confuse the function and purpose of the UVX and UVY relay functions during the blackout condition sequence.

D. Correct, The Containment Spray Pump should not be running with the stated conditions. The loading sequence time to start the pump is 180 seconds and while some equipment timers start when the board voltage is restored, the spray pump timer does not start until both the voltage is restored and the containment pressure reaches 2.81 psig. Since only 2 minutes have elapsed, the timer to start the pump is active but has not timed out. The pump should start when the timer sequence when reached.

If the Main Feed Pump Turbine(MFPT) 2B trips, which ONE (1) of the following identifies the correct status of MFPT 2B Condenser Inlet and Outlet Valves(FCVs) following the trip both before any Operator action is taken and after the AOP-S.01, Loss of Normal Feedwater, has been completed?

Before any After AOP Operator Action Completion A. Closed Open B. Closed Closed C~ Open Open D. Open Closed Page 114

1/2008 Sequoyah SRO NRC Exam 02/08/2008 If one of the MFPTs trip, the Condenser inlet and outlet FCVs will automatically close if the unit is above 60%.

The AFW pumps will automatically start when one MFPT trips if the plant is above 80% as stated in TI-28.

A. Incorrect, With the trip occurring at less than 60%, the AFW pumps would not be running and the condenser valves would not automatically close due to the trip of the MFPT. Plausible if the candidate does not correctly recall the conditions that will cause the automatic closure of the condenser FCVs or the AFW start conditions associated with a MFPT trip or the actions contained in the AOP for loss of a MFPT at less than 77% power.

B. Incorrect, With the trip occurring at less than 60%, the AFW pumps would not be running and the condenser valves would not automatically close due to the trip of the MFPT. Plausible if the candidate does not correctly recall the conditions that will cause the automatic closure of the condenser FCVs or the AFW start conditions associated with a MFPT trip or the actions contained in the AOP for loss of a MFPT at less than 77% power.

C. Correct, with the trip occurring at less than 60%, the valves would remain open and the AFW pumps would remain off. After completing the AOP the valves would remain open as the AOP only directs ensuring the valves are closed if the power level is not less than 60%.

D. Incorrect, with the trip occurring at less than 60%, the valves would remain open and the AFW pumps would remain off. After completing the AOP the valves would remain open as the AOP only directs ensuring the valves are closed if the power level is not less than 60%.

- A main feedwater transient occurs resulting in several alarms.

The Operator notes the following:

- Turbine VPL is approximately 68%.

- Control Rods inserting at 72 step/min.

MFPT 1B SPEED CONTROLLER at 100 % and pump discharge flow increased.

MFPT 1A indicates 0 flow.

MFW reg valves demand at 100 % and S/G levels are below setpoint.

- Steam Dump valves open.

Which ONE (1) of the following identifies the status of MFP 1A and the position of the low pressure (LP) control valves in the steam supply to the MFP 1A turbine?

A. MFP 1A has tripped; LP Control valves OPEN.

B~ MFP 1A has tripped; LP Control valves CLOSED.

C. MFP 1A is NOT tripped but has unloaded; LP Control valves OPEN.

D. MFP 1A is NOT tripped but has unloaded; LP Control valves CLOSED.

Page 117

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, the MFPT has tripped and all stop and control valves would be closed. Plausible because the candidate could confuse the LP control valve response of the MFPT with the control valve response of the AFWP turbine.

On the AFW PT, if the turbine trips, the stop valve trips closed but the control valve goes full open due to loss of oil pressure. However on the MFPT both sets of valves close.

B. Correct, the MFPT has tripped and all control valves would be closed.

C. Incorrect, The valve position limiter would be at near 100% unless a runback occurred and the runback is initiated by a MFPT tripping. If the turbine unloaded, both sets of valves would be closed. Plausible because all other conditions are correct for the unloading of the 1A MFP and the candidate could think that only the HP control valves would be closed if the turbine unloaded but did not trip.

D. Incorrect, The valve position limiter would be at near 100% unless a runback occurred and the runback is initiated by a MFPT tripping. Plausible because all other conditions are correct for the unloading of the 1A MFP and the control valves would be closed and the stop valves open if the turbine unloaded but did not trip. An event similar to this occurred in the plant.

52. Given the following plant conditions and information:

Both Units operating at 100 % power All systems aligned normally If a large ERCW leak developed at the inlet to the 1A1 CCS Heat Exchanger, which ONE (1) of the ERCW Headers would have increased

, flow, and when the leak was isolated, how would the 1A and 2A ERCW header pressures be effected?

Header with Effect on Flow Increase Header Pressure A. 1A Both 1A and 2A header pressures would increase B. 1A Only the 1A header pressure would increase C¥' 2A Both 1A and 2A header pressures would increase D. 2A Only the 2A header pressure would increase Page 130

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, The 1A ERCW supply header is not the header supplying the flow for the 1A1&1A2 CCS Heat Exchangers, the 2A header ERCWis the supply. However, because the headers are common at the pumping station, isolating the leak would cause both 1A and 2A header pressures to increase. Plausible because the component with the leak is a Unit 1 heat exchanger and standard configuration would be for a Unit 1 water header to supply the cooling and if so the flow would increase in the 1A header' and the candidate could correctly relate the reduction in flow when the leak is isolated to only effecting pressures in both the 1A and 2A headers.

B. Incorrect, The 1A ERCW supply header is not the header supplying the flow for the 1A 1&1A2 CCS Heat Exchangers, the 2A header ERCW is the supply. Additionally, because the headers are common at the pumping station, isolating the leak would cause both 1A and 2A header pressures to increase. Plausible because the component with the leak is a Unit 1 heat exchanger and standard configuration would be for a Unit 1 water header to supply the cooling and if so the flow would increase in the 1A header and thecendtdete could relate the reduction in flow when the leak is isolated to only effecting pressure in the 1A header and not consider the connection at the pumping station.

C. Correct. 2A ERCW supply header is the normal supply for the 1A 1& 1A2 CCS Heat Exchangers and the 2A 1&2A2 CCS Heat Exchangers. Isolating the leak would cause both 1A and 2A header pressures to increase because the headers are common at the ERCW Pumping Station.

D. Incorrect. 2A ERCW supply header is the normal supply for the 1A1&1A2 CCS Heat Exchangers and the 2A 1&2A2 CCS Heat Exchangers. However because the headers are common at the pumping station, isolating the leak would cause both 1A and 2A header pressures to increase. Plausible because the flow would increase in only the 2A header and the candidate could relate the reduction in flow when the leak is isolated to only effecting pressure in the 2A header and not consider the connection at the pumping station.

62. With the pump control handswitches in AUTO, which ONE (1) of the following correctly describes operation of the Reactor Coolant Drain Tank (RCDT) pumps when 2-FCV-68-310, PRT Drain to RCDT, is opened to reduce the level in the Pressurizer Relief Tank (PRT)?

A. RCDT Pump A will auto start ONLY if the level in the RCDT is above the low level pump cutoff level switch.

B. RCDT Pump A will auto start EVEN if the level in the RCDT is below the low level pump cutoff level switch.

C. RCDT Pump B will auto start ONLY if the level in the RCDT is above the low level pump cutoff level switch.

D~ RCDT Pump B will auto start EVEN if the level in the RCDT is below the low level pump cutoff level switch.

A. Incorrect, The A pump does not receive a start signal when 2-FCV-68-310 is opened, only the B pump has this start function. Plausible because the candidate could confuse which pump starts when the valve opens and due to the pump having an auto start / trip based on RCDT tank level.

B. Incorrect, The A pump does not receive a start signal when 2-FCV-68-310 is opened, only the B pump has this start function. Plausible because the candidate could confuse which pump starts when the valve opens and due to the pump having an auto start / trip based on RCDT tank level with the trip being bypassed if the valve were open.

C. Incorrect, The B pump will start when 2-FCV-68-310 is opened. The valve open limit switch in the start circuit is in parrallel to the contact that would be open if RCDT level were low. Plausible because there is a level switch that would trip the pump if the RCDT level decreased to the setpoint while pumping down the RCDT, however, this switch is bypassed when 2-FCV-68-310 is opened.

D. Correct, The B pump will start when 2-FCV-68-310 is opened. The valve open limit switch in the start circuit is in parrallel to the contact that would be open if RCDT level were low.

D. Tref would indicate approximately equal to 562°F.

Control rods would move at 48 steps/minute.

Page 174

1/2008 Sequoyah SRO NRC Exam 02/08/2008 Normal Tavg and Tref @ 40% power = 559 0F. Turbine is operated on IMP OUT so when dumps open there is little/no change in Tref which is based on turbine load l.e.

turbine impulse pressure. Therefore, plant will stabilize at approximatel same Tref.

Normal Manual Rod speed in 48 steps per minute. In Bank select, Manual rod speed is 48 Steps/minute for control banks and 64 steps/minute for shutdown banks.

A. Incorrect, The Tref would stabilize at approximately 559°F which is the Tref for 40%

power, however the rod speed in manual is 48 steps per minute. Plausible if the candidate mistakes rod speed in normal manual control with manual rod speed for shutdown banks in banks select which is 64 steps/minute.

B. Incorrect, Tref will not increase to 56?O F since turbine load ts not increasing.

Additional steam load is diverted to steam dump system. Also, normal manual rod speed is not 64 steps/minute. Plausible if the candidate does not realize that Tref does not increase for the steam dump leak and confuses manual shutdown bank rod speed with normal manual rod speed.

C.Correct, Tref will remain at approximately the 40% value of 559°F since turbine load is not increasing when additional steam load is diverted to steam dump system.

Normal manual rod speed is 48 steps/minute.

D. Incorrect, Tref will not increase to 562°F since turbine load is not increasing.

Additional steam load is diverted to steam dump system. Plausible if the candidate does not realize that Tref does not increase for the steam dump leak but correctly remembers that normal manual control rod speed is 48 Steps/min.

At;! HEAT SINK safety function is prioritized HIGHER than the PRESSURIZED THERMAL SHOCK safety function because HEAT SINK has a larger impact on the barriers to a fission product release.

B. HEAT SINK safety function is prioritized HIGHER than the PRESSURIZED THERMAL SHOCK safety function because Heat Sink must exist before a PRESSURIZED THERMAL SHOCK could occur.

C. HEAT SINK safety function is prioritized LOWER than the PRESSURIZED THERMAL SHOCK safety function because a Heat Sink must exist before a PRESSURIZED THERMAL SHOCK could occur.

D. HEAT SINK safety function is prioritized LOWER than the PRESSURIZED THERMAL. SHOCK safety function because PRESSURIZED THERMAL SHOCK has a larger impact on the barriers to a fission product release.

A. Correct. Per EPM-4 HEA T SINK safety function is prioritized HIGHER than the PRESSURIZED THERMAL SHOCK and HEA T SINK has a Larger impact on the barriers to a fission product release.

76. Given the following:

Unit 1 experienced a reactor trip I safety injection due to the inadvertent opening of a pressurizer safety valve.

Reactor Coolant Pumps were stopped due to Phase B after verifying Containment Spray in service.

Plant conditions when the first Emergency Plan classification was made:

Pressurizer pressure 1635 psig and stable Pressurizer level 1000/0 High Quad. Avg. Incore Thermocouple 572°F and stable Lowest Tcold 544°F and stable RVLIS 87% and dropping Steam Generator levels 33% NR and stable Highest Containment Radiation 1.1E+01 Remlhr and stable Containment Hydrogen 0.00/0 Containment Pressure 4.8 psid and dropping Containment Sump Level 14% and rising RCS Activity < Tech Spec limit Which ONE (1) of the following identifies the required initial Emergency Plan classification and the classification required fifty (50) minutes later if the High Quad. Avg. Incore Thermocouple is 743°F and rising with RVLIS at 48 %?

(SED Judgement is NOT to be used as criteria for the declaration)

Reference Provided Initial 50 minutes Classification Later A~ Alert Site Area Emergency B. Alert General Emergency C.. Site Area Emergency Site Area Emergency D. Site Area Emergency General Emergency Page 188

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Correct. Initial conditions result is a loss of 1.2 RCS Barrier EAL 1.2.2 RCS Leakage

/ LOCA due to subcooling being less than 400F and also a potential loss of the same 1.2.2 EAL. NO other EAL criteria are applicable. The 50 minute conditions result the additional Potential Loss of 1.1 Fuel Clad Barrier via 1.1.2, Incore Thermocouple HI Quad Average which can be determined from the information provided. Additionally, EAL 1.1.1, Critical Safety Function Status (Core Cooling Orange) is a Potential Loss of the 1.1.1 Fuel Clad Barrier, but the candidate would have to recall this information (the orange path criteria is not provided). Loss or Potential Loss of any two barriers results in the declaration being a Site Area Emergency.

B. Incorrect. Initial conditions result is a loss of 1.2 RCS Barrier EAL 1.2.2 RCS Leakage / LOCA due to subcooling being less than 400F and also a potential loss of the same 1.2.2 EAL. NO other EAL criteria are applicable. The General Emergency classification is plausible because the candidate could mistakenly determine from the information that criteria for Inadequate Core Cooling exist (FR-C. 1 RED Path) which would result in the loss of 1.1 Fuel Clad barrier and the potential loss of 1.3 Containment Barrier (1.3.1 - Actions of FR-C.1 ineffective due to CETs tending up) which would be a General Emergency. While the upward trend exist, the Core Cooling is NOT a RED Path with the stated conditions. Core Cooling Red Path criteria would have to be recalled correctly to prevent this error.

C. Incorrect. Initial Site Area Emergency is plausible if the candidate misapplies the information provided. The 50 minute classification is correct.

D. Incorrect. Initial Site Area Emergency and the General Emergency classifications are plausible if the candidate misapplies the information provided.

77. Given the following:

Unit 1 operating at 100% power when an ATWS occurred following the trip of both MFPTs.

- All S/G water levels are approximately 4% narrow range and dropping with ONLY the MDAFW pump 1A-A in service supplying 260 gpm to S/G #1 and 190 gpm to S/G #2.

- At the time of entry into FR-S.1 the RCS temperature and pressure are increasing rapidly.

Subsequently, while perfoming FR-S.1, the reactor is successfully tripped and a safety injection occurs on low pressurizer pressure.

Which ONE (1) of the following identifies BOTH the status of the turbine at the time FR-S.1 was entered and the correct procedure implementation as a result of the safety injection?

A':I The turbine is tripped.

Perform steps 1 through 4 of E-O, Reactor Trip or Safety Injection, and ES-0.5, Equipment Verifications, while continuing in FR-S.1.

B. The turbine is tripped.

Performance of steps 1 through 4 of E-O, Reactor Trip or Safety Injection, and ES-0.5, Equipment Verifications, is NOT permitted until FR-S.1 is completed.

Page 191

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Correct, The trip of both MFPs is a turbine trip signal and the turbine is tripped as indicated by the heatup and pressurization of the RCS (if the turbine was not tripped, the RCS would be cooling down and depressurizing). Perform steps 1 through 4 of E-O, Reactor Trip or Safety Injection, and ES-O.5, Equipment Verifications, while continuing in FR:"S.1 would be correct procedure implementation.

B. Incorrect, The trip of both MFPs is a turbine trip signal and the turbine is tripped as indicated by the heatup and pressurization of the RCS (if the turbine was not tripped, the RCS would be cooling down and depressurizing). Procedure implementaion is incorrect. Plausible if student believes no other procdures can be implemented while FR-'S. 1 is in progress.

C. Incorrect, The trip of both MFPs is a turbine trip signal and the turbine is tripped as indicated by the heatup and pressurization of the RCS (if the turbine was not tripped, the RCS would be cooling down and depressurizing). Perform steps 1 through 4 of E-O, Reactor Trip or Safety Injection, and ES-O.5, Equipment Verifications, while continuing in FR-S.1 would be correct procedure implementation.

D. Incorrect, The trip of both MFPs is a turbine trip signal and the turbine is tripped as indicated by the heatup and pressurization of the RCS (if the turbine was not tripped, the RCS would be cooling down and depressurizing).

78. Given the following:

Unit 1 at 4% power, startup in progress in accordance with GO-3, Power Ascension from Reactor Critical to Less than 5 Percent Reactor Power.

- The MFW Bypass Reg valves are controlling steam generator levels in AUTO.

Main Feed Pump (MFP) 1A in service.

Motor Driven Auxiliary Feedwater Pumps have been stopped and placed in A-P AUTO.

Following an inadvertent Feedwater Isolation, the crew enters AOP-S.01, Loss of Normal Feedwater If all 4 SG levels were at 28% and dropping, which ONE (1) of the following identifies the status of the MFW Bypass Reg Valves and the procedure to be in effect when the plant is stabilized?

A. MFW Bypass Reg Valves would be closed; AOP-S.01, Loss of Normal Feedwater.

B~ MFW Bypass Reg Valves would be closed; ES-0.1, Reactor Trip Response.

C. MFW Bypass Reg Valves would be opening; AOP-S.01, Loss of Normal Feedwater.

D. MFW Bypass Reg Valves would be opening; ES-O.1, Reactor Trip Response.

Page 194

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, The valves would be closed due to the FWI, even with the SG levels dropping and Bypass reg valve controllers sending signal to open the valves. The AFW pumps would start due MFP 1B having control power on its trip bus and being in the tripped state resulting in both MFPTs tripped and the AFW would attempt to control SG levels, however with power level above the capability of AFW, the levels would continue to drop. A reactor trip would be required, following by a transition to ES-O.1 where the plant would be stabilized. Plausible because the plant would be stabilized in AOP-S.01 if the power level had been lower in Mode 2 and the candidate may not correctly identify the valves closed by the FWI signal because there is a FWI valve downstream.

B. Correct, The valves would be closed due to the FWI, even with the SG levels dropping and Bypass reg valve controllers sending signal to open the valves. The AFW pumps would start due MFP 1B having control power on its trip bus and being in the tripped state resulting in both MFPTs tripped and the AFW would attempt to control SG levels, however with power level above the capability of AFW, the levels would continue to drop. A reactor trip would be required, following by a transition to ES-O.1 where the plant would be stabilized.

C. Incorrect, Due to SG levels dropping, Bypass reg valve controllers would be a sending signal to open the valves but the FWI would have the valves closed. The AFW pumps would start due MFP 1B having control power on its trip bus and be in the tripped state resulting in both MFPTs tripped which starts AFW pumps. Plausible because the bypass reg valve would normally be responding to the low S/G levels by modulating opening.

Because there is a FWI valve downstream, the candidate may not realize the bypass reg valve is also isolated and because the plant would be stabilized in AOP-S.01 if the power level had been lower in Mode 2.

D. Incorrect, Due to SG levels dropping, Bypass reg valve controllers would be sending a signal to open the valves but the FWI would have the valves closed. The AFW pumps would start due MFP 1B having control power on its trip bus and be in the tripped state resulting in both MFPTs tripped which starts AFW pumps. Plausible because the bypass reg valve would normally be responding to the low S/G levels by modulating opening.

Because there is a FWI valve downstream, the candidate may not realize the bypass reg valve is also isolated. The plant stabilization in ES-O.2 is correct.

B. ABGTS Train A remains OPERABLE until the Train A Containment Air Isolation valve automatically closes, at which time LCO 3.0.3 entry would be required.

C. Both ABGTS Trains would be INOPERABLE with the current conditions.

LCO 3.0.3 entry would NOT be required.

D~ Both ABGTS Trains would be INOPERABLE with the current conditions.

LCO 3.0-.3 entry would be required.

Question requires the knowledge of when the air system can not support the systems that require air and the application of 2 Technical Specifications for ABGTS. Plant Systems LCO 3.7.8 Auxiliary Building Gas Treatment System and Refueling Operations LCO 3.9.12 Auxiliary Building Gas Treatment System.

A. Incorrect, per the ARI 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 TIS 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 occuring at a pressure setting air on decreasing air pressure. The suspension of tuel 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 ARI for the alarm identified in the stem (and AOP-M.2, Page 200

1/2008 Sequoyah SRO NRC Exam 02/08/2008 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 TIS 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 3.30.3 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 ARI 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 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 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.

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Gorrect, If LOGA has not been isolated as per indications given in stem then the procedure forces a Transition to EGA-1.1, Loss of RHR Sump Recirculation and the SI termination would be completed in EGA-1.1.

B. Incorrect, If LOGA has not been isolated as per indications given in stem then the procedure forces a Transition to EGA-1.1, Loss of RHR Sump Recirculation however, the the SI termination would be completed in EGA-1. 1 not in ES-1. 1. Plausible if the candidate knows the transition would be made to EGA-1. 1 but does not know that the EGA will terminate the safety injection.

G. Incorrect, E-1 would be the correct transition if the leak had been isolated.

Isolation is determined by the RGS pressure rising and the stem states that the pressure is dropping. Plausible if the candidate does not know the criteria required to make the transition to E-1 is RGS pressure increasing.

D. Incorrect, E-1 would be the correct transition if the leak had been isolated as determined by the RGS pressure rising and the stem states that the pressure is dropping. Plausible if the candidate does not know the criteria required to make the transition to E-1 is RGS pressure increasing but does know that if E-1 is entered the SI termination would be terminated in ES-1.1.

82. Given the following:

The crew is performing actions of ECA-2.1, "Uncontrolled Depressurization of All Steam Generators."

The RCS subcooling is 48 degrees F.

RCS pressure is 1540 psig and rising.

Pressurizer level is 24% and rising.

- While performing Step 14, MONITOR SI Termination Criteria, the S/G #4 pressure suddenly begins to rise in an uncontrolled manner.

What action is required for this condition?

A. Terminate SI in ECA-2.1, then transition to E.-2, Faulted Steam Generator Isolation.

BY' Transition to E-2, Faulted Steam Generator Isolation, then terminate SI.

C. Remain in ECA-2.1, SI termination criteria are not currently met.

D. Transition to E-2, Faulted Steam Generator Isolation, SI termination criteria are not currently met.

Page 206

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect. The fold out page Event Diagnostics and a caution direct the operator not to transition until SI termination is complete after the SI is reset in Step 15. With termination criteria met at step 14, the caution and fold out page directions do' not apply. The purpose of this caution is to prevent an unnecessary delay in terminating SI; thus, prevent/minimize the potential for repressurizing the ReS (PTS concern). With the termination criteria met prior to this step, the procedure directs the transition to E-2 where SI termination will be directed. Plausible if candidate does not understand the process to start the SI termination process.

B. Correct. The fold out page Event Diagnostics directs the transition to E-2 if SI termination criteria is met unless Step 15 through Step 25 are in progress.

The parameters listed result in meeting SI termination criteria. Meeting the criteria prior to Step 15 which resets the SI and begins the SI termination process, results in the correct action being a transition to E-2 where SI termination will be directed.

c. Incorrect. The Sltermination criteria is met and a transition is required to be made to E-2. Plausible if the candidate misapplies the data given to required SI termination criteria and determines that continuing in ECA-2. 1 is the correct action which would be correct is SI termination criteria was not met.

D. Incorrect. The transition to E-2 is correct however the SI termination is met as provided in the data supplied in the question. Plausible because the candidate could recognize the pressure increasing in the #4 SG as being an criteria for the transition to E-2 but misapply the data given as not meeting SI termination criteria..

AY' Ensures Fuel Rod Integrity is maintained during continued operation.

B. Minimize AFD swings due to xenon redistribution.

C. Removes requirement to determine QPTR using incore probes.

D. Eliminates the requirement to re-evaluate specific accident analysis.

A. Correct, Basis states restriction of thermal power provides assurance of fuel rod integrity during continued operation.

B. Incorrect, Not part of basis and lowering RX power can cause AFD swings.

Plausible due to AFD being affected during a dropped rod event but power reduction is not to minimize AFD swings.

c. Incorrect, Not part of actions/basis for dropped rod. This action is from TS 3.2.4 QPTR. Plausible due to QPTR being affected by a dropped rod, and this is a restriction placed on determining QPTR with power above 75% power with an NI out of service.

D. Incorrect, Accident analysis must be performed to ensure analysis remains valid per Tech Spec action. Plausible due to Accident analysis being a TS action which must be pertormea.

Which ONE (1) of the following identifies the procedural flow path to implement ES-1.1, SI Termination and, the required action in ES-1.1 if the RCS pressure starts to drop and continues to drop following the action to stop the first centrifuqal charging pump (CCP)?

A. Transition to ES-1.1 would be made DIRECTLY from E-2.

Restart the CCP and transition to E-1, Loss of Reactor or Secondary Coolant.

B~ Transition to ES-1.1 would be made DIRECTLY from E-2.

Transition to ES-1.2, Post LOCA Cooldown.

C. No direct transition from E-2 to ES-1.1 can be made, a transition must first be made to E-1, Loss of Reactor or Secondary Coolant.

Restart the CCP and transition to E-1, Loss of Reactor or Secondary Coolant.

D. No direct transition from E-2 to ES-1.1 can be made, a transition must first be made to E-1, Loss of Reactor or Secondary Coolant.

Transition to ES-1.2, Post LOCA Cooldown.

Page 215

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Incorrect, Transition to ES-1.1 would be made directly from E-2 and if the RCS pressure continued to drop following the stopping of the CCP the procedure will direct the transition to ES-1.2. Plausible because the restarting of the CCP and a transition to E-1 would be made from the ES-1.1 Fold Out Page on the procedure under different conditions.

B. Correct, ES-1. 1 would be entered from E-2, and if the RCS pressure continued to drop following the stopping of the CCP, a transition to ES-1.2 is directed.

C. Incorrect, ES-1.1 would be entered directly from E-2, No transition to E-1 would be required, however the candidate might mistakenly conclude that an E-1 transition would have to be made before ES-1.1 could be entered.

Plausible if the candidate was not aware that the direct transition was correct or because the restarting of the CCP and a transition to E-1 would be made from the ES-1.1 Fold Out Page on the procedure under different conditions.

D. Incorrect, ES-1.1 would be entered directly from E-2, No transition to E-1 would be required, however plausible because the candidate might mistakenly conclude that an E-1 transition would have to be made before ES-1.1 could be entered and the transition to ES-1.2 is correct for the pressure response after the CCP is stopped.

alignment, 2 Independent release rate calculations are verified per aDCM 1.1.1. High activity level requires SM approval for release. Plausible if student knows high activity limit but does not know that the SM can authorize the release.

B. Incorrect, 2 Independent samples of tank contents are analyzed, 2 Independent discharge valve alignment, 2 Independent release rate calculations are verified per aDCM 1.1.1. High activity level requires SM approval for release. Plausible if student believes that to release a tank with high activity it would require active monitoring during the release.

c. Correct, 2 Independent samples of tank contents are analyzed, 2 Independent discharge valve alignment, 2 Independent release rate calculations are verified per aDCM 1.1.1. The high activity level requires SM approval for release.

D. Incorrect, 2 Independent samples of tank contents are analyzed, 2 Independent discharge valve alignment, 2 Independent release rate calculations are verified per aDCM 1.1.1. The high activity level requires SM approval for release. Plausible is student does not know requirement to have SM approval for releasing tank with high activity levels. Raising dilution flow adds to the plausibility of being able to release with a higher activity versus getting additional approvals.

99. Given the following:

- Mode 5.

- RCS Boron Concentration = 2210 ppm.

- Required Shutdown Margin Boron Concentration = 2100 ppm.

- RWST Boron Concentration = 2600 ppm.

- Chemistry reports Volume Control Tank Boron Concentration = 2000 ppm due to Primary Water inleakage into the VCT which has now been stopped.

- RCS is being drained to 696' for maintenance, per 0-GO-13, "Reactor Coolant System Drain and Fill Operations."

- RCS level is inadvertently lowered to 695'.

- RHR pump amps, discharge pressure, and flow begin to fluctuate excessively.

Which ONE (1) of the following describes the required action(s) and mitigating response in accordance with AOP-R.03, RHR System Malfunction, and Technical Specifications?

Action Mitigating Response A':" Stop RHR Pump Raise RCS level using RWST gravity fill.

B. Stop RHR Pump Raise RCS level using charging pump taking suction from VCT C. Lower RHR Pump Flow Raise RCS level using RWST rate to 1000 - 1500 gpm gravity fill D. Lower RHR Pump Flow Raise RCS level using charging rate to 1000 - 1500 gpm pump taking suction from VCT Page 250

1/2008 Sequoyah SRO NRC Exam 02/08/2008 A. Correct - The required procedural action to trip the RHR pump is correct. The mitigating 'action is correct due to Tech Spec 3.4.1.4 action requirement to not dilute RCS with concentration less than required by shutdown margin. The RWST Concentration is greater than required SDM concentration.

B. Incorrect - The required procedural action to trip the RHR pump is correct. The mitigating action is incorrect due to Tech Spec 3.4.1.4 action requirement to not dilute RCS with concentration less than required by shutdown margin. The VCT Concentration is less than required SDM concentration. Plausible is student does not remember this requirement.

C. Incorrect - The required procedural action is to trip the RHR pump. Lowering the flow rate is plausible due to procedure containing actions to lower flow rate to the values listed if RCS level is greater than 695' 4". Since RCS level is less than that as stated in the stem then this action would not be performed and is incorrect. The mitigating action is correct due to Tech Spec 3.4.1.4 action requirement to not dilute RCS with concentration less than required by shutdown margin. The RWST Concentration is greater than required SDM concentration.

D. Incorrect - The required procedural action is to trip the RHR pump. Lowering the flow rate is plausible due to procedure containing actions to lower flow rate to the values .

listed if RCS level is greater than 695' 4". Since RCS level is less than that as stated in the stem then this action would not be performed and is incorrect. The mitigating action is incorrect due to Tech Spec 3.4.1.4 action requirement to not dilute RCS with concentration less than required by shutdown margin. The VCT Concentration is less than required SDM concentration.
