A. CORRECT. According to Technical Specification 3.9.1, Boron Concentration "Boron concentrations of the RCS, refueling canal, and the refueling cavity shall be maintained within the limits specified in the COLA (COLA, 2.11 states ~ 2750 ppm)." LCO Action Statement A "Boron concentration not within limit" has a Required Action of "Suspend CORE ALTERATIONS" with a Completion Time of "Immediately".
B. INCORRECT. Plausible since both RHR loops are required to be OPERABLE if cavity level is< 23 feet according to Technical Specification 3.9.5. Incorrect since cavity level is> 23 feet and slowly lowering, Technical Specification 3.9.4requires one RHR loop to be OPERABLE and in operation.
C. INCORRECT. Plausible Technical Specification 3.9.6 requires cavity water level to be maintained ~ 23 feet above the top of the reactor vessel flange and requires an immediate suspension of core alterations if water level is< 23 feet. Incorrect since refueling water cavity level is > 23 feet and slowly lowering, the operating crew has the ability to maintain

RO Question #5 Given the following plant conditions:
- The source of RCS leakage is back-leakage from either V-853A or V-8538, RHR INLET CHECK VALVES TO THE REACTOR VESSEL CORE DELUGE LINE
- The leak location is on the common RHR HX discharge line to the reactor vessel and Loop '8' cold leg
- The crew has transitioned from E-0, REACTOR TRIP OR SAFETY INJECTION, to the appropriate procedure Which of the following identifies:
(1) The component that, when closed, would result in leak isolation, AND (2) The SI flow change as a result of the successful leak isolation.

ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Answer: C Explanation (Optional):
A. INCORRECT. Plausible because MOV-720 is checked in ECA-1.2, but it is a verification of a normally shut valve for a normal alignment. For the given conditions there would be NO change in parameters even if the valve had started from the OPEN position as back-flow leakage would not be isolated. Second part is plausible, if candidate does not know that leak isolation would cause RCS pressure to rise and SI flow to lower, due to SI pumps approaching dead head conditions.
B. INCORRECT. Plausible because MOV-720 is checked in ECA-1.2, but it is a verification of a normally shut valve for a normal alignment. For the given conditions there would be NO change in parameters even if the valve had started from the OPEN position as back-flow leakage would not be isolated. The second part is correct.
C. CORRECT. In accordance with ECA-1.2, MOV-852A and MOV-852B are closed one at a time to attempt leak isolation. Since the given leak location is upstream of failed check valve 853A or 853B, isolation is accomplished once MOV-852A or MOV-852B is closed.
ECA-1.2 uses indication of RCS pressure rising for leak isolation which corresponds to SI flow lowering as repressurization occurs.
D. INCORRECT. Plausible as the first part is correct and the candidate may confuse the RCS pressure response with the applicable SI flow response.

PCV-135 eosition RV-203 eosition A. OPEN CLOSED B. OPEN OPEN C. CLOSED CLOSED D. CLOSED OPEN Answer: D Explanation (Optional):
A. INCORRECT. Plausible if the candidate does not recognize that PT-135 senses pressure upstream of PCV-135 which results in the valve closing to attempt to raise pressure. Also, plausible if the candidate does not recognize that Relief Valve 209 is located downstream of PCV-135 and therefore will not lift.
B. INCORRECT. Plausible if the candidate does not recognize that PT-135 senses pressure upstream of PCV-135 which results in the valve closing to attempt to raise pressure. Also, the second part is correct.
C. INCORRECT. Plausible since the first part is correct and if the candidate does not
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet recognize that Relief Valve 209 is located downstream of PCV-135 and therefore will not lift.
D. CORRECT. PCV-135 controller would get a low input for letdown system pressure and compare that to the setpoint (normally 250 psig). The controller would then send a control signal to CLOSE PCV-135 in an attempt to raise pressure, but would not see a change due to the failed pressure transmitter. Eventually PCV-135 would CLOSE causing Relief Valve 203 to lift at 600 psig to the PRT.

D. No transition required, continue performing ES-1.3 to ensure a source of water is aligned to provide core cooling.
Answer: D
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Explanation (Optional):
A. INCORRECT. Plausible because the basis for transitioning to FR-C.2 is correct. Incorrect because ES-1.3 contains a NOTE prior to step 3 that precludes transitioning to FR Procedures until after step 12 is complete. Also, FR-C.2 contains a CAUTION prior to step 13 "The following step will cause SI Accumulator injection which may result in a RED path condition in F-0.4, Integrity Status Tree." This procedure should be completed before transition to FR-P.1, Response to Imminent Pressurized Thermal Shock."
B. INCORRECT. Plausible because a RED condition on the Integrity CSFST would require a transition to FR-P.1; however, ES-1.3 contains a NOTE prior to step 3 that precludes transitioning to FR Procedures until after step 12 is complete.
C. INCORRECT. Plausible because FR-H.1 is the most urgent FR Procedure with the given conditions and would be transitioned to in most cases during the EOPs. Incorrect because ES-1.3 contains a NOTE prior to step 3 that precludes transitioning to FR Procedures until after step 12 is complete.
D. CORRECT. In accordance with ES-1.3, NOTE prior to step 3 "Steps 3 through 12 should be performed without delay. FR procedures should not be implemented prior to completion of these steps." ES-1.3 Background Document states "A suction source of water for the SI pumps must be maintained to provide core cooling.

SI initiation will ...
A. cause Service Water isolation to allow maximum Service Water cooling.
B. ensure all Service Water Pumps are running to maximize Containment cooling.
C. provide feedline isolation to isolate Feedwater leakage and stop Containment pressure rise.
D. ensures maximum Service Water flow to Containment Recirc Fan Coolers.
Answer: D Explanation (Optional):
A. INCORRECT. Incorrect because for Service Water Isolation to occur there must be an undervoltage condition on either Bus 14 or 16 concurrent with an SI signal. Plausible since the purpose of Service Water isolation is to ensure that adequate cooling is provided for safeguards equipment.
B. INCORRECT. Incorrect since the Safety Injection sequencer does not ensure that all four SW Pumps are running, only the two that are selected to automatically start. Plausible since under normal conditions the non-running Service Water Pumps are selected to automatically start on a Safety Injection signal, so following a LOCA all four SW Pumps could be running.
C. INCORRECT. Plausible since the Safety Injection signal will result in a Feedwater Isolation signal. However, it will not prevent the contents of a SIG with a ruptured feed line inside Containment from being emptied into CNMT causing CNMT pressure rise.

D. 1) Condensate Pump and Condensate Booster Pump motor bearing temperatures will slowly rise.
- 2) Perform a reactor trip.
Answer: A
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Explanation (Optional):
A. CORRECT. In accordance with 33013-1251, Sheet 1, Service Water provides cooling for the Condensate Pump motor bearings. Therefore, with only one Service Water Pump running, reduced cooling will be supplied to the Condensate Pump motor bearings resulting in rising temperatures. The Condensate Booster Pump motor bearings are not supplied with Service Water cooling so the temperatures should remain relatively steady. AP-SW.2, step 5 RNO requires a load reduction with only one Service Water Pump running and plant equipment temperatures rising (given that plant conditions continue to degrade).
B. INCORRECT. Plausible since the first part is correct and AP-SW.2, step 2 RNO directs the operators to trip the reactor if no Service Water Pumps are running.
C. INCORRECT. Plausible since Service Water provides cooling for the Condensate Pump motor bearings and the candidate may believe that Service Water cooling is also provided to the Condensate Booster Pump motor bearings. Also, the second part is correct.
D. INCORRECT. Plausible since Service Water provides cooling for the Condensate Pump motor bearings and the candidate may believe that Service Water cooling is also provided to the Condensate Booster Pump motor bearings.

Which ONE of the following correctly states the trend during the SHUTDOWN AND the reason?
Actual leak rate will ____ during the shutdown. (Assume that the geometric size of the flaw remains constant).
A. Rise; RCS temperature is lowered, causing greater density of primary fluid.
B. Rise; because the secondary plant's saturation pressure is reduced as power is lowered.
C. Lower; RCS temperature is lowered, causing greater density of primary fluid.
D. Lower; because the primary to secondary pressure difference is reduced as power is lowered.
Answer: D Explanation (Optional):
A. INCORRECT. Plausible since the RCS density will rise as power is reduced and temperature lowers in the RCS. However, this does not have much of an effect on leak rate.
B. INCORRECT. Plausible since this is the effect that would occur if turbine power were maintained constant with RCS temperature lowering.
C. INCORRECT. Plausible since the first part is correct and RCS density will rise as power is reduced and temperature lowers in the RCS. However, this does not have much of an effect on leak rate.
D. CORRECT. As reactor power is reduced, S/G pressure rises resulting in a lower differential pressure across the tube leak causing S/G leak rate to lower. In accordance with AP-SG.1 Background Document for step 7 "There is information that suggests that merely reducing

- 2) manually reduce turbine load
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Answer: D Explanation (Optional):
A. INCORRECT. Plausible since a dropped rod with the plant operating at power will result in a lower total reactor power since the turbine EHC controls are in OPER PAN - IMP OUT.
Also, AP-RCC.3, step 6 allows for dilution of the RCS to raise T AVG after the initial load reduction to match temperatures is completed in step 3.
B. INCORRECT. Plausible since a dropped rod with the plant operating at power will result in a lower total reactor power since the turbine EHC controls are in OPER PAN - IMP OUT.
The second part is correct.
C. INCORRECT. Plausible since the first part is correct and AP-RCC.3, step 6 allows for dilution of the RCS to raise T AVG after the initial load reduction to match temperatures is completed in step 3.
D. CORRECT. Reactor power initially drops due to the negative reactivity insertion from the control rod. Since the turbine EHC controls are in OPER PAN - IMP IN, the Turbine Control Valves will OPEN to maintain turbine first stage pressure constant. This results in total reactor power returning to approximately the initial value. In accordance with AP-RCC.3 RNO, step 3 with TAvG less than T REF, the operator is instructed to lower turbine load manually to match temperatures.

B. INCORRECT. Plausible since ER-ELEC.1 places Bus 14 back on its normal power supply; however, the normal feed breaker control switch must be held in the CLOSE position and the DIG BUS 14 Supply Breaker OPEN for the normal feed breaker to CLOSE. Also, AP-ELEC.14/16 is plausible since this is the procedure the operator would use for a loss of Bus 14.
C. CORRECT. According to 10905-0101, Sheet 1, once the DIG Bus 14 Supply Breaker control switch is taken to After-Trip position, since the breaker is open, the DIG is up to speed and voltage, the X Relay would energize causing the Closing Coil to energize closing the DIG Bus 14 Supply Breaker. According to 10905-0065, Sheet 1, the control switch for the Bus 14 Normal Feed Breaker must be taken to the CLOSE position to energize the X Relay and subsequently the Closing Coil to close the breaker. ER-ELEC.1, Section 6.5 directs the operator actions necessary to transfer Bus 14 from the DIG to Offsite Power.
D. INCORRECT. Plausible since the first part is correct and AP-ELEC.14/16 is plausible since this is the procedure the operator would use for a loss of Bus 14.

ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Answer: C Explanation (Optional):
A. INCORRECT. Plausible as the first part is correct and Charging flow is established in the EOP network to establish normal RCP seal cooling. Since there is no Safety Injection signal present, 'B' CCW Pump will be running providing labyrinth seal cooling for the RCS which is cooling the RCP seals.
B. INCORRECT. Plausible as the candidate may not recognize that 'C' Charging Pump has tripped on undervoltage and Charging flow is established in the EOP network to establish normal RCP seal cooling. Since there is no Safety Injection signal present, 'B' CCW Pump will be running providing labyrinth seal cooling for the RCS which is cooling the RCP seals.
C. CORRECT. With the loss of Circuit 767, all Offsite Power is lost and 'B' EOG starts and re-energizes Buses 16 and 17. 'A' Charging Pump is stopped due to 'A' EOG failing to start and Bus 14 being de-energized; 'C' Charging Pump is lost (UV trip) due to Bus 16 being de-energized momentarily until 'B' EOG re-energizes Bus 16. Therefore, no Charging Pumps are running when the operating crew reaches Step 14 of AP-ELEC.1. In accordance with AP-ELEC.1 Background Document, "In this step charging is restored in preparation for restoring letdown."
D. INCORRECT. Plausible as the candidate may not recognize that 'C' Charging Pump has tripped on undervoltage and the second part is correct.

A. INCORRECT. Plausible because ECA-1.1 does provide the overriding guidance for Containment Spray Pump operation and the parameters given are 2 of 3 used to determine the required number of CNMT Spray Pumps. Incorrect because the number of running Containment Spray Pumps is dependent upon a combination of RWST level, Recirc Fans available, and Containment pressure.

- 2) Both MDAFW Pump flows will remain stable D. 1) No
- 2) Both MDAFW Pump flows will lower and stabilize at a lower value Answer: B
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Explanation (Optional):
A. INCORRECT. Plausible because first part is correct. Second part is incorrect as SIG pressure will rise with T AVG which will go to ARV setpoint in this plant condition, 1050 psig.
This will cause lower Auxiliary Feedwater flow. The second part is plausible since AFW flows are relatively stable post-trip with no extenuating events.
B. CORRECT. Following the reactor trip and safety injection, both MDAFW Pumps started and their respective discharge valve fully opened and then throttled back to approximately 215 gpm. Since 'B' MSIV was not closed for 2 minutes, 'B' SIG pressure was much lower than
'A' SIG pressure when the MDAFW Pumps started and the discharge valves automatically throttled. Once 'B' MSIV was closed, the pressure in 'B' SIG started to rise resulting in 'B' MDAFW Pump flow to lower (with no operator actions). As RCS TAvG continues to rise back to no-load value, the pressure in the S/Gs will rise and stabilize at the ARV setpoints (1050 psig). With no operator actions, MDAFW Pump flow will lower and stabilize at a new lower value due to pumping to a higher pressure S/G.
C. INCORRECT. Plausible if candidate does not know that MDAFW Pump throttle back is a one-time event following pump start and will throttle back to current Steam Generator pressure. Second part is incorrect as S/G pressure will rise with TAVG which will go to ARV setpoint in this plant condition, 1050 psig. This will cause lower Auxiliary Feedwater flow.
The second part is plausible since AFW flows are relatively stable post-trip with no extenuating events.
D. INCORRECT. Plausible if candidate does not know that MDAFW Pump throttle back is a one-time event following pump start and will throttle back to current Steam Generator pressure. Second part is correct.

A. CORRECT. In accordance with ECA-1.1 Background Document for step 28 "Since the RWST is now empty at this time, all pumps still taking suction from the RWST are stopped, with the exception that one SI pump is left running to provide some injection flow." The purpose of this step is to minimize RWST outflow.
B. INCORRECT. Plausible since the first part is correct and one of the major objectives of ECA-1.1 is "to minimize thermal stresses in the reactor vessel and remain within the ORANGE and RED priority limits of the Integrity Status Tree" by limiting the cooldown rate to 100°F/hr. Incorrect since this is the basis for maintaining the cooldown rate to less than 100°F/hr.
C. INCORRECT. Plausible since the candidate may recognize that all but one ECCS Pump are stopped, and since the given RCS pressure is< 300 psig and RHR Pumps are injecting, may believe that an RHR Pump remains running. The second part is correct.
D. INCORRECT. Plausible since the candidate may recognize that all but one ECCS Pump are stopped, and since the given RCS pressure is< 300 psig and RHR Pumps are injecting, may believe that an RHR Pump remains running. The second part is plausible since one of the major objectives of ECA-1.1 is "to minimize thermal stresses in the reactor vessel and remain within the ORANGE and RED priority limits of the Integrity Status Tree" by limiting the cooldown rate to 100°F/hr.

E-1 will transition to ES-1.1 on indications of RCS repressurization.
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Answer: D Explanation (Optional):
A. INCORRECT. Plausible since E-0 has a transition step to E-1 and the candidate may not have the procedural knowledge to recognize that the E-2 transition step occurs prior to the E-1 transition step in E-0. Also plausible because E-1 contains a transition step to E-2 if the faulted SIG has not already been isolated.
B. INCORRECT. Plausible since the transition from E-0 is correct and the final transition will be to ES-1.1. Incorrect because E-2 will transition to E-1 prior to the final transition to ES-1.1.
C. INCORRECT. Plausible since E-0 step 1 has a transition to FR-S.1 if the reactor cannot be tripped. Incorrect because E-0, step 1 RNO contains actions for the operator to open Bus 13 and Bus 15 Normal Feeder Breakers to trip the Rod Drive MG Sets and E-2 will transition to E-1 prior to the final transition to ES-1.1. Also plausible if the candidate believes that this action occurs in FR-S.1 vice E-0.
D. CORRECT. In accordance with E-0, step 15, the operator is directed to go to E-2 if any SIG pressure is lowering in an uncontrolled manner. The operator then performs E-2 and transitions to E-1 at step 9. The operator will then perform E-1 through step 15, returning to step 1 until 'B' SIG is dry and the RCS repressurizes.

- Electric plant is in a normal 50/50 lineup
- Power Range Nuclear Instrument N-44 has been defeated for maintenance
- Source Range Nuclear Instrument N-32 is selected to audible indication

A. 1. CANNOT
- 2. Both Source Ranges are INOPERABLE B. 1.CANNOT
- 2. N-31 is OPERABLE and only one Source Range is required Answer: A
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Explanation (Optional):
A. CORRECT. In accordance with P-12 a loss of Offsite Power Circuit 7T, with 'A' EOG failure, will result in Bus 14 being de-energized which causes Instrument Bus 'B' losing power. This will cause a loss of Power Range Nuclear Instrument N-42. Loss of the second PRNI will cause Permissive P-10 to de-energize resulting in a block of Source Range High Voltage, de-energizing both SRNls.
B. INCORRECT. Plausible since the first part is correct and the candidate may believe that only one Source Range Instrument is required since a majority of safety systems utilize a redundant instrument/component scheme where only half the instruments/components are required. Also, the audible count instrument is powered from Instrument Bus 'D' which remains energized in this event.
- C. INCORRECT. Plausible since Source Range Nuclear Instruments receive power from Instrument Buses A and C, which will not lose power. Instrument Bus 'A' receives normal power from Bus 14 (which is de-energized); however, the 'A' Station Main Battery will automatically assume the Instrument Bus load upon loss of power to the associated Battery Charger. Instrument Bus 'C' receives normal power from Bus 16.
D. INCORRECT. Plausible since Source Range Instrument N-32 used to receive power from Instrument Bus 'B', which would be de-energized with the given plant conditions. Also, the candidate may believe that only one Source Range Instrument is required since a majority of safety systems utilize a redundant instrument/component scheme where only half the instruments/components are required.

NOTE: If either ECA-3.2, SGTR WITH LOSS OF REACTOR COOLANT-SATURATED RECOVERY DESIRED or ES-1.3, TRANSFER TO COLD LEG RECIRCULATION is in effect, this procedure should not be performed.
Which ONE of the following describes the basis for the ECA-3.2 exception in this NOTE?
FR-C.3 directs the operator to ...
A. restore Letdown, while ECA-3.2 maintains Letdown isolated.
B. re-establish ECCS to raise subcooling, while ECA-3.2 attempts to terminate SI flow.
C. close any open PRZR PORVs, while ECA-3.2 opens PORVs to depressurize the RCS.
D. allow a RCS cooldown rate in excess of 100°F/hr, while ECA-3.2 limits the cooldown rate.
Answer: B Explanation (Optional):
A. INCORRECT. Plausible since ECA-3.2 does address getting letdown restored, but FR-C.3 does not. If the candidate does not fully understand the overall big picture of ECA-3.2 and FR-C.3 this may seem plausible.
B. CORRECT. In accordance with FR-C.3 Background Document "FR-C.3 directs a reestablishment of RCS subcooling via safety injection flow. This is inconsistent with actions specified in ECA-3.2 which reduce RCS subcooling via SI flow reduction in order to

ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Answer: C Explanation (Optional):
A. INCORRECT. Plausible since according to P-1, loss of both Gire Water Pumps and the P-7 Permissive (8% reactor power) would result a reactor trip due to Turbine trip. This would be an uncomplicated trip so the transition to ES-0.1 would be normal.
B. INCORRECT. Plausible since according to P-1, loss of both Gire Water Pumps and the P-7 Permissive (8% reactor power) would result a reactor trip due to Turbine trip. Also, ES-0.2 is procedure used when natural circulation cooldown is required.
C. CORRECT. In accordance with AP-CW.1 "This procedure provides the actions necessary to respond to a loss of a Gire Water Pump while the plant is at power." According to AP-CW .1, step 1 RNO "IF power less than 8%, THEN verify Turbine trip and go to AP-TURB.1".
D. INCORRECT. Plausible since the initial procedure entered is correct and AP-TURB.4 would be the procedure used for lowering condenser vacuum which is plausible since condenser vacuum would start to degrade with the given plant conditions; however, the transition to AP-TURB.1 occurs first.

- Plant was at 100% power
- A LOCA and loss of Offsite Power Circuit 767 occurred
- An automatic Reactor trip and Safety Injection occurred
- The operating crew entered E-0, REACTOR TRIP OR SAFETY INJECTION, and have transitioned to E-1, LOSS OF REACTOR OR SECONDARY COOLANT, and are evaluating restoration of Instrument Air The following plant conditions are present:
- Instrument Air pressure is 55 psig and slowly lowering
- No Air Compressors are running
- Bus 14 is powered from Offsite Power Circuit 7T and is carrying 275 amps
- Bus 16 is powered by 'B' Diesel Generator which is carrying 2240 kW
- Bus 14 is cross tied to Bus 13
- Bus 16 is cross tied to Bus 15
- Air compressor start will raise load 6 amps or 75 kW What actions will the Unit Supervisor take in accordance with E-1 to restore adequate Instrument Air pressure, if necessary?
A. Start Service Air Compressor B. Start 'C' Instrument Air Compressor C. Start Diesel Air Compressor D. Instrument Air pressure meets E-1 step criteria, refer to AP-IA.1, LOSS OF INSTRUMENT AIR
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Answer: C Explanation (Optional):
A. INCORRECT. Plausible since E-1, step 9.c RNO directs the operator to start electric air compressor(s) as power supply permits. The Service Air Compressor is normally started because it does not rely upon the SW System for cooling and can carry the air systems by itself. Incorrect because starting the Service Air Compressor (power supply is Bus 13) would result in exceeding 278 amps on Bus 14.
B. INCORRECT. Plausible since E-1, step 9.c RNO directs the operator to start electric air compressor(s) as power supply permits. The 'C' Instrument Air Compressor is normally started, if Service Air Compressor is not available, because it can carry the air systems by itself. Incorrect because starting the 'C' Instrument Air Compressor (power supply is Bus
- 15) would result in exceeding 2300 kW on 'B' Diesel Generator (EOP CAUTION).
C. CORRECT. In accordance with E-1, step 9.c RNO directs the operator to start electric air compressor(s) as power supply permits. The NOTE prior to this step "IF starting non-safeguards equipment will result in exceeding 278 amps (yellow line) on Buses 14 or 16, THEN DO NOT start non-safeguards equipment." Since starting any electric air compressor would result in exceeding the limits on Bus 14 or 'B' EOG, then the RNO states "IF electric air compressors CAN NOT be started THEN start the diesel air compressor and tie in to Instrument Air.
D. INCORRECT. Plausible if the candidate does not know the pressure requirement for adequate Instrument Air pressure and since E-1, step 9.d RNO directs the operator to refer to AP-IA.1 if Instrument Air pressure is not greater than 60 psig or lowering.

Question Cognitive Level: Memory or Fundamental Knowledge Comprehension or Analysis x 10 CFR Part 55 Content: 55.41 55.43 .5 Comments: KIA is matched because the question requires the candidate to recognize that the electrical buses which supply power to the electric air compressors are cross-ties to the safeguards buses. Starting any of the electric air compressors will result in the associated safeguards bus to exceed the current (Bus 14) or DIG load (Bus 16) limit. Therefore, the candidate must apply the NOTEs in the EOPs and determine that an electric air compressor cannot be started.
