Effects of RCP coastdown on RCS parameters Question # 1 The RCP ___(1)___ reactor trip is designed to ensure an adequate RCP coastdown time by tripping all RCP breakers.
Adequate coastdown time is designed to provide protection against violating ___(2)___
limits.
A. (1) undervoltage (2) Departure from Nucleate Boiling B. (1) underfrequency (2) Departure from Nucleate Boiling C. (1) undervoltage (2) Peak Fuel Centerline Temperature D. (1) underfrequency (2) Peak Fuel Centerline Temperature Answer: B Page 1 of 58 CPNPP 2020-05 retake NRC Written Exam Worksheet 1-10 Rev. 2
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
This question matches the KA by requiring knowledge of RCP underfrequency tripping requirements and the effect of coastdown on core cooling, which without coastdown would lead to violating DNBR limits.
Explanation:
A. Incorrect. Second part is correct. First part is plausible since breakers commonly are designed to trip on undervoltage, but the underfrequency trip is the only one of the two that opens the RCP breakers.
B. Correct. This reactor trip anticipates a loss of coolant flow and helps prevent exceeding DNBR limits by establishing natural circulation. Besides tripping the reactor, it also trips all RCP breakers to extend pump coastdown time.
C. Incorrect. First part plausibility described in "A" above. PCT is plausible since it is a limit of concern in TS, but is based on overpower and not loss of flow.
D. Incorrect. First part is correct. Second part plausibility described in "C" above.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
Match to K/A because question requires knowledge of setpoint for diversion to the VCT and the reason for bypassing CVCS demins.
Explanation:
A. Correct. TCV-129 automatically diverts when TI-130 reaches 135oF. This diversion prevents damage to the CVCS demin resin.
B. Incorrect. Plausible since 1st part is correct (see A). 2nd part is plausible since boron retention in the resin is affected by temperature, but high temperature releases boron, resulting in a boration.
C. Incorrect. Plausible since TCV-129 will divert on high temperature of 155oF, but this is measured at the inlet to BTRS, not at TI-130. 2nd part is correct (see A).
D. Incorrect. 1st part is plausible (see C). 2nd part is plausible (see B).

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of EOP caution related to Emergency Core Cooling System.
Explanation:
A. Incorrect. 1st part is correct (see B). 2nd part is incorrect, but plausible because SIPs have higher flow capacity which might imply they could cavitate first, but the CCP has a higher suction line.
B. Correct. 1st part is correct. Caution states that the ECCS pumps should be secured at RWST empty (if still taking a suction from RWST). 2nd part is correct. The CCP should be stopped first due to the suction line to the CCPs being physically higher than the SIP suction.
C. Incorrect. 1st part is incorrect, but plausible because this is the level that the CSPs are stopped, but CCPs and SIPs are stopped at empty level. 2nd part is incorrect, but plausible (see A).
D. Incorrect. 1st part is incorrect, but plausible (see C). 2nd part is correct (see B).

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
This question matches the KA by requiring knowledge of the interface between possible leakage paths from the RCS and the inputs to the PRT.
Explanation:
A. Incorrect. Plausible because vessel head leak off flow is directed to within Containment, however, but it goes to atmosphere.
B. Incorrect. Plausible because excess letdown divert valve is directed to a tank within Containment, however, it is the Reactor Coolant Drain Tank (RCDT).
C. Correct. The Chemical and Volume Control System Letdown Relief Line Valve goes to the Pressurizer Relief Tank.
D. Incorrect. Plausible because one might assume that the RHR Pump CL Injection Relief went to the PRT, however, it goes to the HUT. The RHR suction relief goes to the PRT.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
Question matches K/A by requiring knowledge of how to determine the temperature indication downstream of leaking valve.
Explanation:
A. Incorrect. Plausible since this is saturation temperature for 1.1 psig (16 psia), but saturation for PRT conditions is 284oF which is correct.
B. Incorrect. Plausible since this is saturation temperature for 23 psia, but saturation for PRT conditions is 284oF which is correct. 23 psia could be used if incorrectly coverts 38 psig to psia.
C. Incorrect. Plausible since this is saturation temperature for 38 psia, but saturation for PRT conditions is 284oF which is correct. 38 psia could be used if incorrectly fails to convert 38 psig to psia.
D. Correct. Constant enthalpy through valve results in a temperature at saturation for the pressure downstream, 38 psig (53 psia) and 284oF Technical Reference(s) Steam Tables Attached w/ Revision # See Comments / Reference Proposed references to be provided during examination: Steam Tables Learning Objective: EXPLAIN the normal, abnormal and emergency operation of the Pressurizer Pressure and Level Control System in accordance with ABN-705, Pressurizer Pressure Malfunction, and ABN-706, Pressurizer Level Instrumentation Malfunction.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
Matches the KA by requiring knowledge of the effect on SSW system as a result of operations performed on the CCW heat exchanger.
Explanation:
A. Correct. Isolating the SSW side and opening the drains on the CCW side of the heat exchanger will prevent chloride infusion into the CCW side of the CCW heat exchanger in the event of a tube leak in the HX. At operating conditions this is prevented due to CCW pressure being greater than SSW.
B. Incorrect. Plausible a CCW leak to SSW in the HX could cause hydrazine to enter the SSI, but with CCW depressurized any leakage would be into CCW.
C. Incorrect. Plausible since a maximum differential pressure would exist across the HX tubes with CCW depressurized, but HX pressure will not be higher than during normal operations.
D. Incorrect. Plausible since SSW cools the CCW HX and without CCW it might be considered that no heat source exists in the HX, but this will not cause thermal stresses to exist.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match since knowledge of failure of redundant channels is required.
Explanation:
A. Incorrect. First part is correct (See B below). Second part is incorrect but plausible because may believe that the CS signal is energize to actuate which would cause CS auto actuation.
B. Correct. First part is correct because the containment high pressure SI signal is a 2/3 coincidence which is de-energize to actuate. With channel III de-energized due to the loss of power to 2PC3 which de-energizes 2-PT-935, plus the failure of 2-PT-936 (channel II) the 2/3 coincidence is met causing an auto SI. Second part is correct because the CS signal is 2/4 coincidence and energize to actuate. With channel III de-energized due to the loss of 2PC3 and the failure of 2-PT-936 (channel II) which is energize to actuate for the CS signal there is only 1/4 coincidence met and Containment Spray will not actuate.
C. Incorrect. First part is incorrect but plausible since one of the two signals is energized to actuate and the other is de-energized to actuate, but SI is de-energize to actuate and CS is energized to actuate and must recall which is which. Second part is incorrect but plausible (See A above).
D. Incorrect. First part is incorrect but plausible (See C above). Second part is correct (See B above).

K/A match due to requiring understanding of when automatic Main Steam Line Isolation signals are enabled and blocked.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible as the pressure is only slightly above the pressure where P-11 occurs, permitting the manual block. 2nd part is correct (see B).
B. Correct. 1st part is correct. SI cannot be blocked until pressurizer pressure drops below P-11, which is 1960 psig. 2nd part is correct. Since SI is not blocked, the low steamline pressure MSLI signal is still active. The high steamline pressure rate signal is enabled only when SI is blocked below P-11.
C. Incorrect. 1st part is incorrect, but plausible (see A). 2nd part is incorrect, but plausible since the high pressure negative rate is the only signal which will cause a MSLI after SI has been blocked.
D. Incorrect. 1st part is correct (see B). 2nd part is incorrect, but plausible (see C).

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring ability to determine how operator should control FW following a failure needing intervention.
Explanation:
A. Correct. Unit 1 program P is 80 to 181 psid from 20% power to 100% power. At 60% power, the P should be established at 131 psid. Since steam pressure failed low, the FWP speed will have decreased and must be raised.
B. Incorrect. Plausible since speed should be raised, but 141 psid is the value that would be calculated if program P were ramped from 80 to 181 psid from 0% power to 100% power, instead of 20% to 100%.
C. Incorrect. Plausible since the program P should be established at 131 psid, but the speed must be raised and not lowered. Lowering speed is plausible if incorrectly believes the failed channel causes speed to increase.
D. Incorrect. Plausible since 141 psid is the value that would be calculated if program P were ramped from 80 to 181 psid from 0% power to 100% power, instead of 20% to 100%. Lowering speed is plausible if incorrectly believes the failed channel causes speed to increase.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of AFW recirc valve response to low flow condition indicated by failed flow detector.
Explanation:
A. Incorrect. Plausible if thought that this would cause the discharge valve to close, but it has no effect on the discharge.
B. Incorrect. Plausible since the pump will be running at runout conditions and suction pressure will lower, but there is no low suction pressure trip.
C. Incorrect. Plausible since the pump will be running at runout conditions and discharge pressure will lower, but there is no low discharge pressure trip.
D. Correct. Flow is limited to 800 gpm per MDAFW pump, and is currently at 700 gpm. With the loss of discharge flow, the recirc valve will open, causing an additional 200 gpm of flow and flow limits will be exceeded.

A. EDG 1-02 B. CCP 1-02 C. EDG 2-02 D. CCP 2-02 Answer: B Page 45 of 73 CPNPP 2020-05 retake NRC Written Exam Worksheet 11-20 Rev. 1
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of power supplies to major AC system loads.
Explanation:
A. Incorrect. Plausible because the fault on XST2 will cause a loss of the preferred offsite power supply to 1EA2 but the slow transfer to the alternate offsite power supply will occur prior to the EDG getting a start signal. EDG 1-02 does not start and is thus not running without cooling.
B. Correct. The fault on XST2 will cause a loss of the preferred offsite power supply to 1EA2 which will result in the Blackout Sequencer operating. The Blackout Sequencer will start CCP 1-02 and should also start SSWP 1-02. Since the malfunction is a failure of the SSWP 1-02 to start, CCP 1-02 which is cooled by SSW is running without cooling water.
C. Incorrect. Plausible because the loss of XST2 will affect both units. However, the effect on Unit 2 is the loss of the alternate power supply to 2EA2 and thus the Blackout Sequencer does not operate for Unit 2 and there is no affected train of equipment.
D. Incorrect. Plausible because the loss of XST2 will affect both units. However, the effect on Unit 2 is the loss of the alternate power supply to 2EA2 and thus the Blackout Sequencer does not operate for Unit 2 and there is no affected train of equipment.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring understanding of the cautions associated with recovering from a loss of AC power and the TS implications.
Explanation:
A. Correct. The Blackout Sequencer starts the associated train MDAFW Pump. The BOS OL starts the TDAFWP. Placing a pump in PULLOUT or throttling AFW flow above 10%
power renders the train inoperable. The TDAFW Pump should be allowed to run until the BOS OL clears and the MDAFW Pumps should be allowed to run until the Blackout Sequencer is reset.
B. Incorrect. Plausible since the pumps must be allowed to continue to operate until the respective start signal is removed, but this means for the TDAFWP when the OL clears and for the MDAFWPs when the BOS is reset.
C. Incorrect. Plausible since the MDAFWPs are stopped after the BOS is reset, but placing the TDAFWP in PULLOUT or throttling AFW flow above 10% power renders the train inoperable.
D. Incorrect. Plausible since the TDAFWP is stopped after the BOS OL clears, but placing the MDAFWPs in PULLOUT or throttling AFW flow above 10% power renders the trains inoperable.

Date: Rev. 0 Tier 2 Group 2 K/A 011.K5.15 Level of Difficulty: 2 Importance Rating 3.6 Pressurizer Level Control: Knowledge of the operational implications of the following concepts as they apply to the PZR LCS: PZR level indication when RCS is saturated.
Question # 30 Given the following conditions:
A Unit 1 Reactor Trip has occurred concurrent with a Loss of Offsite Power.
EOS-0.4A, Natural Circulation Cooldown with Steam Void in Vessel (without RVLIS),
is in progress.
The crew is depressurizing the RCS using Auxiliary Spray.
During the depressurization to the target pressure of 800 psig, Pressurizer level rapidly increases to 92% when RCS pressure is 950 psig.
What has caused the rapid increase in Pressurizer Level?
A. CVCS Letdown has isolated B. A Pressurizer PORV has failed open C. The Auxiliary Spray Valve has failed closed D. The bubble in the Reactor Vessel Head has expanded Answer: D Page 48 of 52 CPNPP 2020-05 retake NRC Written Exam Worksheet 21-30 Rev. 2
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to needing to understand the relationship between the RCS reaching saturation conditions in the Reactor Vessel Head and the response of pressurizer level.
Explanation:
A. Incorrect. Plausible since isolating letdown will cause inventory to increase in the RCS, but it would be a controlled level increase and not a rapid level rise.
B. Incorrect. Plausible since opening a PORV would cause pressurizer level to rise, but the cause of the rapid rise is reaching saturation conditions in the vessel head, shifting water from the head to the pressurizer.
C. Incorrect. Plausible since use of the Auxiliary Spray Valve is directed in the procedure and the rapidly rising pressurizer level is an undesirable outcome from the actions being taken, so it may be considered that the directed action has failed.
D. Correct. Upper head voiding during the depressurization results in rapidly increasing pressurizer level.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of how system responds to a failed radiation monitor.
Explanation:
A. Incorrect. Plausible since CLOSED is the normal position of this valve during a release and only select automatic actions occur as a result of a radiation monitor operate failure. This is one of the monitors where automatic actions occur, so the valve will reposition to its open position.
Examples of other rad monitors which do not provide automatic actions on an operate failure include containment air gas/particulate, CR radiation, and secondary sample.
B. Incorrect. Plausible if thought normal release flowpath is to Co-Current Waste, however 1-RV-5100A will close isolating the Low Volume Waste flowpath and 1-RV-5100B will open aligning the Co-Current Waste flowpath.
C. Correct. On a rad monitor operate failure, the automatic action for these valves will occur. The normal release path is to Low Volume Waste, so 1-RV-5100A will close isolating the Low Volume Waste flowpath and 1-RV-5100B will open, aligning the Co-Current Waste flowpath.
D. Incorrect. Plausible if thought that 1-RV-5100A and 1-RV-5100B remain in their current position on a rad monitior operate failure since only select automatic actions occur as a result of a radiation monitor operate failure, and the normal position for 1-RV-5100B is open. Examples of other rad monitors which do not provide automatic actions on an operate failure include containment air gas/particulate, CR radiation, and secondary sample.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of how the SG water level control system responds in automatic to changing inputs.
Explanation:
A. Incorrect. Incorrect, but plausible since steam flow fails high, causing the controlling valve to fail open, but at this power level the FCV is in AUTO control with the FCBV closed in MAN.
B. Incorrect. Incorrect, but plausible if thought that the high failure of the pressure compensation would result is a lower steam flow due to the density difference and that the FCBV is controlling in AUTO at this power level.
C. Correct. A high failure of steam pressure causes the associated steam flow channel to fail high, causing FK-510 to open to match feed flow to steam flow. At this power level the FCV is in service in AUTO and the FCBV is closed in MAN.
D. Incorrect. Incorrect, but plausible if thought that the high failure of the pressure compensation would result is a lower steam flow due to the density difference and the FCV is controlling in AUTO at this power level.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of the time associated with the long lived delayed neutrons and the resultant startup rate.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible (see C). 2nd part is incorrect, but plausible (see B).
B. Incorrect. 1st part is correct (see D). 2nd part is incorrect, but plausible since overcompensation would effect the time response of the IR channel, but overcompensation would cause the SR to energize earlier.
C. Incorrect. 1st part is incorrect, but plausible if thought that a startup rate of -1 dpm would be achieved following a trip, resulting in a time of 5-8 minutes before the SR energizes. 2nd part is correct (see D).
D. Correct. 1st part is correct. Based on a prompt drop and subsequent response due to long lived delayed neutrons, a startup rate of -1/3 dpm will cause power to be below P-6 within 15-18 minutes (5-6 decades). 2nd part is correct. Failure of the SR to energize after this time frame is due to an IR channel being undercompensated and stabilizing above P-6.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring understanding of the response of pressurizer level to a vapor space leak.
Explanation:
A. Correct. A Pressurizer steam space leak will cause pressure to decrease and level to rise due to the expansion of Reactor Coolant System fluid. The break will cause pressure to lower in the steam space of the Pressurizer. As the RCS pressure lowers, saturation conditions will be reached which will cause voids to form and a two-phase mixture to flow into the Pressurizer, resulting in an increase in Pressurizer level indication.
B. Incorrect. Plausible because for all LOCAs except the Pressurizer vapor space break, Pressurizer level indication decreases. Pressure increasing is plausible if thought that ECCS flow exceeds break flow, causing the RCS pressure to rise.
C. Incorrect. Plausible because pressure will decrease, however, level will rise due to the expansion of Reactor Coolant System fluid.
D. Incorrect. Plausible because level will increase, however, Pressurizer pressure will decrease.
Pressure increasing is plausible if thought that ECCS flow exceeds break flow, causing the RCS pressure to rise as the RCS goes solid.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to being required to know the plant parameters that are used to determine the size of a LOCA.
Explanation:
A. Incorrect. Plausible since this parameter is used to determine if EOP-1.0 can be exited, but the transition path for ECCS flow reduction is to EOS-1.1, Safety Injection Termination.
B. Incorrect. Plausible since RV level is used in procedures where pressurizer level is not considered reliable, but the parameter used is RCS pressure.
C. Incorrect. Plausible since this parameter is used to determine if EOP-1.0 can be exited, but the transition path for ECCS flow reduction is to EOS-1.1, Safety Injection Termination.
D. Correct. A check of RCS pressure is made to determine if pressure is above the shutoff head of the RHR pumps and, if not, whether or not the RHR pumps are injecting. If the RHR pumps are not injecting, a transition is made to EOS-1.2, and if they are injecting EOP-1.0 implementation continues.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to being required to know the tripping criteria for the RCPs.
Explanation:
A. Incorrect. Plausible since in inadequate core cooling conditions, RCPs are not tripped even if conditions to operate the RCPs are not met, but inadequate core cooling does not exist even with CETs rising and RCPs are tripped due to a loss of CCW to the motors and bearing coolers.
B. Incorrect. Plausible since RCPs are not tripped due to a loss of subcooling if ECCS pumps are not available and a CCP trip may be confused with this condition, but they are tripped due to a loss of cooling to the pump coolers.
C. Incorrect. Plausible since RCPs should be stopped, but the reason in this case is due to the loss of CCW. Spray water on the motors is plausible since old versions of ALMs required the RCPs be tripped when sprayed upon.
D. Correct. With containment pressure above the Hi-3 setpoint, Phase B actuation would have occurred resulting in a loss of CCW flow to the RCP motor and bearing coolers. The RCPs are required to be tripped under these conditions.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to being required to know methods of restoring pressure control following a loss of pressure control during a SGTR event.
Explanation:
A. Incorrect. Plausible since PORVs would result in a loss of inventory when opened, but PORVs are used before aux spray due to letdown being isolated.
B. Incorrect. Plausible since PORVs would result in rupturing the PRT after being opened, but PORVs are used before aux spray due to letdown being isolated.
C. Correct. PORVs are used before aux spray due to letdown being isolated, preventing thermal fracture of the pressurizer spray nozzle.
D. Incorrect. Plausible since PORVs are used before Aux Spray and it could be thought charging flow is unavailable with SI in service, but it is because of letdown being isolated.

A tube rupture has occurred on SG 1-03 The SG has been isolated The RCS has been cooled down and depressurized SI has been terminated Normal charging has been established Normal letdown has been established SG 1-03 level is 74% and slowly rising Pressurizer level is 55% and slowly rising Which of the following actions should be taken to establish stable Pressurizer level and SG 1-03 level?
A. Use Pressurizer spray to lower RCS pressure while raising charging flow B. Use Pressurizer heaters to raise RCS pressure while raising charging flow C. Use Pressurizer heaters to raise RCS pressure while lowering charging flow D. Use Pressurizer spray to lower RCS pressure while lowering charging flow Answer: D Page 33 of 45 CPNPP 2020-05 retake NRC Written Exam Worksheet 41-50 Rev. 3
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring understanding of the relationship between the RCS and ruptured SG and how Przr spray is used to control equilibrium conditions.
Explanation:
A. Incorrect. Plausible since spray flow should be used to lower RCS pressure and since pressurizer level is to be maintained between 50-70%, plausible that being at lower end of level band requires more charging, but lowering RCS pressure will result in SG draining back into RCS, so charging flow is to be lowered. If pressurizer level were below 30% (or 50% if Adverse Containment conditions existed) then charging flow would be required to be raised as well.
B. Incorrect. Plausible since using heaters to raise pressure would be the proper action if SG level were lowering, and since pressurizer level is to be maintained between 50-70%, plausible that being at lower end of level band requires more charging, but lowering RCS pressure will result in SG draining back into RCS, so charging flow is to be lowered. If pressurizer level were below 30% (or 50% if Adverse Containment conditions existed) then charging flow would be required to be raised as well.
C. Incorrect. Plausible since charging flow is to be lowered, but with rising SG level, RCS pressure is to be lowered, not raised.
D. Correct. With Pressurizer level between 50% and 75% and SG level rising, the RCS pressure is to be lowered using spray and charging flow is to be lowered.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of how flow rate changes with changes in differential pressure.
Explanation:
A. Incorrect. Plausible if the square root were neglected and the ratio in pressures were used was incorrectly determined to be 0.25 instead of 0.5.
B. Incorrect. Plausible if the square root were accounted for but the ratio in pressures were used was incorrectly determined to be 0.25 instead of 0.5.
C. Incorrect. Plausible if thought the ratio were the new differential pressure to the original differential pressure, without accounting for the square root.
D. Correct. The relationship between differential pressure and flow rate is based on the square root of the ratio of the new pressure to the old pressure. With a new pressure of 400 psig and an original pressure of 800 psig, the ratio is 0.5. The square root of 0.5 is approximately 0.707. 0.707 x 600,000 lbm/hr = 424,000 lbm/hr.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
This question matches the KA by requiring knowledge of the effect on components that respond to a loss of DC power.
Explanation:
A. Correct. Plausible because Reactor Trip Breaker A CANNOT trip due to a shunt trip as the shunt trip coil is powered from 1ED1 and is energized to actuate, so it can only trip on an undervoltage trip which are deenergized to actuate. The TDAFWP steam supply fails open on the loss of 1ED1.
B. Incorrect. Reactor Trip Breaker A CANNOT trip due to a shunt trip as the shunt trip coil is powered from 1ED1 and is energized to actuate, so it can only trip on an undervoltage trip which are deenergized to actuate. The TDAFWP steam supply fails open on the loss of 1ED1, but is plausible as air operated valves can fail either open or closed.
C. Incorrect. Plausible because Reactor Trip Breaker A CANNOT trip due to a shunt trip as the shunt trip coil is powered from 1ED1 and is energized to actuate, so it can only trip on an undervoltage trip which are deenergized to actuate, which is a common misconception as to which is energized to actuate. The TDAFWP steam supply fails open on the loss of 1ED1.
D. Incorrect. Plausible because Reactor Trip Breaker A CANNOT trip due to a shunt trip as the shunt trip coil is powered from 1ED1 and is energized to actuate, so it can only trip on an undervoltage trip which are deenergized to actuate, which is a common misconception as to which is energized to actuate.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of when the reactor will trip on a loss of IA.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible because per ABN-301 the MSIVs fail closed, but the valves are operated by compressed nitrogen and do not immediately close on loss of IA. 2nd part is correct. A manual reactor trip is to be initiated if IA pressure drops below 35 psig.
B. Incorrect. 1st part is incorrect, but plausible (see A). 2nd part is incorrect, but plausible because ABN-301 uses this value of pressure as a minimum value to maintain in the system while recovering from a loss of IA and the low pressure alarm value is 85 psig.
C. Correct. 1st part is correct. Per ABN-301 the FCVs failed closed which will lead to a reactor trip on SG lo-lo levels. 2nd part is correct. ABN-301 directs a manual trip of the reactor if IA falls below 35 psig.
D. Incorrect. 1st part is correct (see C). 2nd part is incorrect, but plausible (see B).

A LOCA outside containment has resulted in unsafe radiological conditions in the Auxiliary Building The crew has taken all the actions of ECA-1.2A, LOCA Outside Containment, to isolate the break RCS subcooling is 0ºF Which of the following is the primary indication used in ECA-1.2A that the actions taken have been successful?
A. RCS pressure increasing B. Auxiliary Building sump level alarms clearing C. PRZR level increasing D. Auxiliary Building temperatures decreasing Answer: A Page 21 of 63 CPNPP 2020-05 retake NRC Written Exam Worksheet 51-60 Rev. 3
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
Matches the KA due to requiring knowledge of the interrelations between a LOCA outside containment and heat removal systems (RCS).
Explanation:
A. Correct. Without being able to perform a visual inspection of the AB due to rad levels being at an unsafe level, the only means used to determine if the LOCA outside containment is isolated is RCS pressure increasing per ECA-1.2.
B. Incorrect. Plausible since this may be indicative of leak being isolated, but is not the primary means used in ECA-1.2.
C. Incorrect. Plausible since this could potentially be indicative of the leak being isolated, but with the RCS being at saturation conditions an increase in PRZR level may be indicative of voiding in the RCS as well as indication of the leak being isolated.
D. Incorrect. Plausible since this may be indicative of leak being isolated, but is not the primary means used in ECA-1.2.

Question # 55 Given the following conditions:
Unit 2 has experienced a LOCA.
During performance of EOP-1.0B, Loss of Reactor or Secondary Coolant, the crew determined that RHR Pump 2-01 was NOT available and that Bus 2EA2 was de-energized.
RWST level is currently 43% and lowering.
Containment pressure is 12 psig and rising slowly.
The Unit Supervisor transitions to ECA-1.1B, Loss of Emergency Coolant Recirculation, and reads the following CAUTION:
If offsite power is lost after SI reset, manual action may be required to restore safeguards equipment to desired status.
The SI and SI sequencers are subsequently reset.
In accordance with ECA-1.1B, the primary operational concern regarding the above CAUTION is that the Train A ____ must be manually re-started.
A. SIP B. CCP C. CSPs D. CCWP Answer: A Page 25 of 63 CPNPP 2020-05 retake NRC Written Exam Worksheet 51-60 Rev. 3
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of the effect on equipment necessary for plant recovery in ECA-1.1 when also responding to a malfunction (loss of power) which affects the equipment.
Explanation:
A. Correct. The only ECCS Pumps available are Centrifugal Charging Pump 2-01 which would auto restart on the BOS and Safety Injection Pump 2-01 which would need to be manually started.
B. Incorrect. Plausible because a concern is always that cooling to the RCP seals is occurring. If the Centrifugal Charging Pump did not restart, manually restarting would be required. However, the CCP receives an auto start from the BOS.
C. Incorrect. Plausible because the CSPs do not receive an autostart signal from the BOS, and if needed, would be required to be manually started, but these pumps are not currently required to be operating although they would have been previously operating before the loss of offsite power would occur.
D. Incorrect. Plausible because a concern is always that cooling to the safeguards loads is occurring. If the Component Cooling Pump did not restart, manually restarting would be required.
However, the CCWP receives an auto start from the BOS.

Question # 56 Given the following conditions:
A LBLOCA has occurred on Unit 1.
The STA reports that a RED path condition exists on HEAT SINK following implementation of the CSFSTs.
A transition is made to FRH-0.1A, Response to Loss of Secondary Heat Sink.
Upon entering FRH-0.1A the following conditions exist:
o All SG levels are between 10% NR and 20% NR.
o All MFW Pumps and AFW Pumps have tripped.
o All SG pressures are 300 psig and slowly decreasing.
o RCS pressure is 120 psig and stable.
Why would the crew be directed to return to the procedure and step in effect as soon as the above conditions are verified?
A. SG levels are sufficient as a heat sink.
B. Feed and bleed is ineffective in removing heat at this RCS pressure.
C. SG thermal shock could result in tube failures and feedwater should NOT be established.
D. Establishing a secondary heat sink would NOT provide any additional heat removal from the RCS.
Answer: D Page 33 of 63 CPNPP 2020-05 retake NRC Written Exam Worksheet 51-60 Rev. 3
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of relationship between RCS and secondary heat sink following a loss of feedwater.
Explanation:
A. Incorrect. Plausible since this level would direct the crew to exit the FRH if this were Unit 2, but the required level is higher on Unit 1 and the reason for exiting is that a secondary heat sink does not provide additional heat removal on a LBLOCA.
B. Incorrect. Plausible since bleed and feed criteria are met, but a secondary heat sink is not required.
C. Incorrect. Plausible since feeding a SG can result in thermal or mechanical shock in accordance with the caution prior to Step 1 and the applicant may consider that FW flow should not be established based on this, but this caution warns the operator to stop feeding the SG if it does fault.
D. Correct. A heat sink is not required if RCS pressure is below non-faulted SG pressure. Adequate heat/energy is being removed via the break under these conditions. A near immediate transition is made out of FRH-0.1 to the procedure and step in effect under these conditions. SG pressures dropping under these conditions is expected as the RCS is removing heat from the SGs.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of what signals from the rod control are used to recover a dropped rod and the required switches to enable the inputs to the rod control system under these conditions. The only inputs used to recover a dropped/slipped rod are the rod bank selector switch, the rod disconnect switches, and the shim switch.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible (see C). 2nd part is correct (see B).
B. Correct. 1st part is correct. Due to an urgent failure in the associated power cabinet, control rods are prevented from moving in all but the individual (CBD) position. 2nd part is correct. The urgent failure occurs as a result of opening the lift disconnect switches for the remaining rods in the other groups power cabinet, 1BD, to prevent them from moving.
C. Incorrect. 1st part is incorrect, but plausible since control bank D rods are normally moved with the bank selector switch in the MAN position. 2nd part is incorrect, but plausible (see D).
D. Incorrect. 1st part is correct (see B). 2nd part is incorrect, but plausible since rods in power cabinet 2BD are also disconnected, but one rod in the group, the dropped rod, remaining connected results in no urgent failure in that power cabinet.

Explanation:
A. Incorrect. First part is incorrect but plausible (See C below). Second part is incorrect but plausible (See B below).
B. Incorrect. First part is correct (See D below). Second part is incorrect but plausible because the applicant could think that stopping steam flow into the main condenser will stop the heat input and protect the condenser from overheat not overpressure. Saturation temperature for 12.3 Hg is approximately 170oF. Overheating is addressed by opening the exhaust hood spray valve when temperature exceeds 194oF.
C. Incorrect. First part is incorrect but plausible in that the Unit 2 set point for MFP trip is 17.5"Hg.
Second part is correct (See D below).
D. Correct. First part is correct in that C-9 is lost when condenser vacuum drops below 12.3"Hg.
Second part is correct in that C-9 will be lost and the steam dump valves close to protect the condenser from rupture due to overpressure.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of control room requirements regarding High Flux at SD alarm during refueling operations.
Explanation:
A. Incorrect. First part is incorrect but plausible (See C below). Second part is correct (See B below).
B. Correct. First part is correct as RFO-102 states alarm may be set at 300 cps or 5 times measured count rate however it also states that 300 cps is the normal setpoint. Second part is correct as RFO-102 states alarm may be blocked if SR is continuously monitored by the operator and an ICRR is performed by nuclear engineering.
C. Incorrect. First part is incorrect but plausible as RFO-102 allows setting alarm at 300 cps or 5 times measured count rate however the alarm is normally set at 300 cps. 75 cps could be thought correct as this is 3 times measured rate. Second part is incorrect (See D below).
D. Incorrect. First part is correct (See B above). Second part is incorrect but plausible because applicant may believe that alarm must be in service during core alterations (i.e.
fuel movement).

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match:
K/A match due to requiring knowledge of administrative requirements during refueling operations.
Explanation:
A. Incorrect. Plausible since the COLR limit is the minimum required by TS, but the administrative limit for boron concentration during refueling is 2400 ppm. It could be thought that if the higher limit were not met that both RHR pumps would be required to be operable and capable of adding RWST water with a concentration of greater than 2400 ppm.
B. Correct. With refueling cavity level less than 23 feet above the flange in MODE 6, two RHR loops are required to be operable, with one in operation.
C. Incorrect. Plausible since SIPs are required to be maintained available during MODE 6 reduced inventory operations in the event of a loss of RHR capability, but during actual fuel movement the SIPs are not required due to the high water level.
D. Incorrect. Plausible since movement of spent fuel inside containment must be suspended if cavity level is less than 23 feet, but even with both trains of RHR operable, movement cannot be restarted.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the impact of improper RWST boron concentration and the requirements to adjust boron concentration.
SRO Only: SRO Only due to requiring knowledge of TS bases associated with potential reactivity affects on the RCS per 10 CFR 55.43(b)(2).
Explanation:
A. Incorrect. Plausible because concern is that the time to HL recirc may not be valid, but the time to correct the boron concentration is 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, though reasons for the RWST being inoperable, such as level, permit only 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to correct.
B. Correct. The required boron concentration of the RWST is 2400-2600 ppm. The upper limits is used to determine the maximum allowable time to switch to HL recirc following a LOCA to avoid boron precipitation in the core following the accident. If outside this limit, 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> are permitted to correct.
C. Incorrect. Plausible because the lower limit of RWST concentration is associated with both sump concentration, but the upper limit is based on sump pH and transfer times to HL recirc. The time to correct the boron concentration is 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, though reasons for the RWST being inoperable, such as level, permit only 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to correct.

This temperature ensures ___(2)___.
A. (1) 350ºF (2) SI accumulator water is injected, while minimizing the nitrogen injected.
B. (1) 350ºF (2) adequate RCS subcooling without further SI accumulator injection.
C. (1) 405ºF (2) SI accumulator water is injected, while minimizing the nitrogen injected.
D. (1) 405ºF (2) adequate RCS subcooling without further SI accumulator injection.
Answer: C Page 14 of 29 CPNPP 2020-05 retake NRC Written Exam Worksheet 76-80 Rev. 2
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the bases of ECCS equipment while operating in the ERGs.
SRO Only: SRO Only due to requiring knowledge beyond that expected for a Reactor Operator.
The hot leg temperatures for isolating the SI accumulators is well beyond the overall mitigation strategy of EOP-1.0A. An RO only needs to know that the accumulators are to be isolated to prevent nitrogen injection into the RCS if not needed.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible since this temperature is a common value used in the ERG network, but it is the temperature at which ECCS must be locked out and LTOP made available. 2nd part is correct (see C).
B. Incorrect. 1st part is incorrect, but plausible (see A). 2nd part is incorrect, but plausible since the accumulators are designed to cover the core upon injection, which may be considered as providing subcooling. This temperature is based upon minimizing nitrogen injection.
C. Correct. 1st part is correct. This is the temperature identified in EOP-1.0 for isolating accumulators after injection. 2nd part is correct. This ensures that RCS saturation pressure exceeds SI accumulator pressure after the water is injected, but before the nitrogen is injected.
D. Incorrect. 1st part is correct (see C). 2nd part is incorrect, but plausible (see B).

Question # 79 Given the following conditions:
Following a Main Steam Line Break, the actions of EOP-2.0A, Faulted SG Isolation, are being performed.
MSIVs have been manually closed.
SG 1-02 has been identified as the faulted SG and has been isolated.
The following Containment conditions and alarms are noted:
o 1-ALB-3A, 4.6, CNTMT NR PRESS HI/LO, is LIT.
o NR Containment Pressures are indicating 1.3 psig and rising slowly.
The following SG 1-02 conditions and alarms are noted:
o 1-ALB-8A, MSL 2 1 OF 3 PRESS LO, is LIT.
o 1-ALB-8A, SG 2 1 OF 4 LVL LO-LO, is LIT.
o SG 1-02 is completely depressurized.
Based on the above alarms and indications, the steam break is located ___(1)___
containment.
To ensure the SG 1-02 MSIV remains closed, direct the FSS to ___(2)___.
A. (1) outside (2) align Battery Charger BC1D24 to Battery BT1D2 B. (1) inside (2) align Battery Charger BC1D24 to Battery BT1D2 C. (1) outside (2) isolate and vent IA off the valve regulator D. (1) inside (2) isolate and vent IA off the valve regulator Answer: A Page 18 of 29 CPNPP 2020-05 retake NRC Written Exam Worksheet 76-80 Rev. 2
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the alarms that will require specific ERG actions to be implemented.
SRO Only: SRO Only due to requiring analysis of the plant conditions, assessment of the plant response to the conditions, and identification of the proper procedure and actions to address the failure per 10 CFR 55.43(b)(5).
Explanation:
A. Correct. 1st part is correct. During the performance of EOP-2.0A, a determination is made as to whether the steam break is inside or outside containment based primarily on containment pressure. At this pressure, with the SG completely depressurized, the abnormal pressure inside containment is likely due to loss of containment cooling. 2nd part is correct. If outside containment, Attachment 2 of EOP-2.0A is performed to align BC1D2 or BC1D24 to BT1D2 since the power supply to BC1D2 is load shed on SI and the degradation of BT1D2 in an adverse environment may cause the MSIVs to open. This action is taken to ensure the MSIVs remain closed.
B. Incorrect. 1st part is incorrect, but plausible since containment pressure is abnormally high, but this is likely due to a loss of containment cooling on the SI. 2nd part is correct (see A).
C. Incorrect. 1st part is correct (see A). 2nd part is incorrect, but plausible since isolating IA and venting it from the MSIV operator is how the MSIV is locally closed in the event it fails to closed from the control room.
D. Incorrect. 1st part is incorrect, but plausible (see B). 2nd part is incorrect, but plausible (see C).

SRO Only: SRO Only due to requiring an assessment of plant conditions and then the selection of a section of a procedure to mitigate or recover, or with which to proceed.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible because there is a TRM limit for temperature and the exhaust fan draws air through the battery room, however, the reason for placing the battery on float is for hydrogen concentration. 2nd part is correct. The procedure that directs placing the battery on float is correct, ALM-0112A, 2.4.
B. Incorrect. 1st part is incorrect, but plausible (see A). 2nd part is plausible since room temperature would direct starting a second fan, but the correct procedure is ALM-0112A, 2.4.

SRO Only: SRO Only due to requiring demonstration of the knowledge of diagnostic steps including the action required to be performed based on not obtaining the Action/Expected Response and thus implementing a Response Not Obtained action.
Explanation:
A. Correct. Part 1 is correct as a response to the negative reactivity insertion from the dropped control rod, the RCS average temperature will lower resulting in a demand for rod withdrawal.
Control Rod Bank D will withdraw until the C-11 rod stop is reached at 223 steps withdrawn. Part 2 is correct in accordance with ABN-712, when the operator identifies that power is not less than or equal to 100% on the highest reading NI the RNO must be implemented. The RNO requires a load reduction to 1100 MW. Following the load reduction, 1/1-RBSS is placed in MANUAL.
B. Incorrect. Part 1 is incorrect but plausible if the applicant did not account for the C-11 rod stop and in such case the Control Rod Bank D rods would withdraw to the full out position of 231 steps withdrawn as RCS temperature remains well below TREF. Part 2 is correct as described in A above.
C. Incorrect. Part 1 is correct as described in A above. Part 2 is incorrect but plausible if the required load reduction is thought to be 50 MWe.
D. Incorrect. Part 1 is incorrect but plausible as described in B above. Part 2 is incorrect but plausible as described in C above.

B. OT N-16 Rod Stop C. OT N-16 Reactor Trip D. PR Overpower Rod Stop Answer: C Page 9 of 72 CPNPP 2020-05 retake NRC Written Exam Worksheet 81-90 Rev. 3
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the effect of a loss of power has on non-nuclear instrumentation.
SRO Only: SRO Only due to requiring application of generic LCO requirements (TS 3.0.3) since the LCO (TS 3.3.1) cannot be met as tripping the required OTN-16 bistables from the second instrument failure will result in a Reactor Trip. The Unit must be placed in MODE 3 within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.
Explanation:
A. Incorrect. Plausible since this is a valid Reactor Protection bistable associated with a failure of a PR NI channel, but there will only be a single pressurizer high power reactor trip bistable tripped if this channel is placed in trip.
B. Incorrect. Plausible since this is a valid Reactor Protection bistable associated with a failure of PR NI channel, but this is a rod stop which can be bypassed at the NI cabinets.
C. Correct. Inputs to OT N-16 are power, pressure, and temperature. One pressure bistable (Channel I) is already tripped. The second OT N-16 (Channel III) cannot be tripped without causing a reactor trip. Therefore, because the ACTION cannot be completed, a shutdown is required by TS 3.0.3.
D. Incorrect. Plausible since this is a valid Reactor Protection bistable associated with a failure of PR NI channel but this is a rod stop which can be bypassed at the NI cabinets.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the limitations associated with operating the steam dump system during low power operations.
SRO Only: SRO Only due to requiring assessment of plant conditions and then selecting a procedure to mitigate or recover from the condition, or with which to proceed.
Explanation:
A. Correct. 1st part is correct as this is directed by IPO-003A. 2nd part is correct. LP Turbine casing T is to be addressed by reducing steam dump flow while maintaining power constant and lowering the heat input into the LP condensers.
B. Incorrect. 1st part is correct (see A). 2nd part is incorrect, but plausible since procedure states to adjust, not necessarily raise, blowdown flow in some places and this may be incorrectly thought to meet that requirement.
C. Incorrect. 1st part is plausible, but incorrect, since ABN-401 has a section regarding turbine casing T, but it addresses the HP turbine casing. 2nd part is correct (see A).
A. Incorrect. 1st part is plausible, but incorrect (see C). 2nd part is plausible, but incorrect (see B).

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge and priority of alarms associated with the RCPs.
SRO Only: SRO Only due to requiring assessment of abnormal plant conditions and then selecting a procedure section to mitigate or recover from the condition, or with which to proceed.
Explanation:
A. Correct. 1st part is correct. With total #1 seal flow greater than 8 gpm at 8.20 gpm (total =
- 1 seal leakoff + assumed 1 gpm for #2 seal leakoff with alarm dark, thus 7.20 + 1 = 8.20 gpm), a Reactor Trip is directed to enable securing the RCP. 2nd part is correct, the failure requiring a trip is a #1 seal failure.
B. Incorrect. 1st part is correct (see A). 2nd part is incorrect, but plausible, since entry condtions are met for entry into Section 6 to address the RCP vibration, but no trip or power reduction is required unless conditions worsen.
C. Incorrect. 1st part is incorrect, but plausible. An orderly shutdown would be required per Section 4 if the leak rate were below 8 gpm and indication is only greater than 7.2 gpm.
The SRO must recognize that 1 gpm must be added for #2 seal, causing the value to exceed the RCP trip criteria. 2nd part is correct (see A).
D. Incorrect. 1st part is incorrect, but plausible (see C). 2nd part is plausible, but incorrect (see B).

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the maximum allowed deviation between pressure channels to determine the operability of a channel.
SRO Only: SRO Only due to requiring the ability to apply the required actions of TS in accordance with the rules of application requirements, as well as the bases for the TS, and values contained within the COLR.
Explanation:
A. Incorrect. Plausible since with 4 operable channels the value used for DNB limits would be 2220 psig, but the channel is outside the maximum allowed deviation and is considered inoperable.
B. Incorrect. Plausible since average of the operable channels is used for DNB limits, and with 4 operable channels, the value would be 2220 psig, but the channel is outside the maximum allowed deviation and is considered inoperable.
C. Incorrect. Plausible since the maximum allowed deviation between pressurizer pressure channels is 60 psig and PI-457 is 75 psig less than any other operable channel. With only 3 pressurizer channels operable, the average of the 3 must be > 2222 psig to meet TS limits, not the highest channel.
D. Correct. Maximum allowed deviation between pressurizer pressure channels is 60 psig and PI-457 is 75 psig less than any other operable channel. With only 3 pressurizer channels operable, the average of the 3 must be > 2222 psig to meet TS limits.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the bases in TS for AFW and AMSAC actuation.
SRO Only: SRO Only due to requiring knowledge of the bases in technical specifications.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible since either first stage pressure channel failing below 40% load will result in AMSAC blocking after 260 seconds. At this time, manual action would be required. 2nd part is incorrect, but plausible since AMSAC is an autostart signal to the AFW pumps. However, IAW the bases in 3.7.5, the autostart from AMSAC is not required for AFW operability.
B. Incorrect. 1st part is correct (see D). 2nd part is incorrect, but plausible (see A).
C. Incorrect. 1st part is incorrect, but plausible (see A). 2nd part is correct (see D).
D. Correct. 1st part is correct. AMSAC will function even with one first stage pressure channel failing below 40% load for 260 seconds before it will no longer function. 2nd part is correct. IAW the bases in 3.7.5, the autostart from AMSAC is not required for AFW operability.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the conditions starting an AFW pump automatically, as well as the reasons for the pump start.
SRO Only: SRO Only due to requiring knowledge of the TS bases associated with the start of the AFW pumps.
Explanation:
A. Incorrect. Plausible since a single SG lowering to 37% on Unit 1 would start both Motor Driven AFW Pumps, however, on Unit 2 the level would need to lower to 35.4%. According to Technical Specification (TS) LCO 3.3.2 Bases, the reason for the AFW Pump start is to ensure at least one SG is available to act as a heat sink.
B. Correct. At 18% power only one Main Feedwater Pump would be in operation, however, the other Main Feedwater Pump would either be in a tripped condition or the trip oil pressure switches isolated to indicate a trip to the RPS. Thus, a trip of the operating Main Feedwater Pump would start both motor driven AFW Pumps. According to TS LCO 3.3.2 Bases, the reason for the AFW pump start is to ensure at least one SG is available to act as a heat sink.
C. Incorrect. Plausible since a single SG lowering to 37% on Unit 1 would start both Motor Driven AFW Pumps, however on Unit 2 the level would need to lower to 35.4%. According to TS LCO 3.3.2 Bases, the reason as stated is incorrect in that the start signal only ensures at least ONE SG is available and not TWO. The distractor is plausible as Unit 1 requires two SG for SGTR recovery in accordance with the FSAR.
D. Incorrect. Plausible since the signal for starting the Motor Driven AFW Pumps is correct, however, the reason as stated is incorrect in that the start signal only ensures at least ONE SG is available and not TWO. The distractor is plausible as Unit 1 requires two SG for SGTR recovery in accordance with the FSAR.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the SSWP when recovering from a loss of all AC power using the APG.
SRO Only: SRO Only due to requiring assessment of plant conditions and selecting a procedure to mitigate or recover from the condition.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible (see C). 2nd part is incorrect, but plausible (see B).
B. Incorrect. 1st part is correct (see D). 2nd part is incorrect, but plausible because there are no indications of any RCS pressure boundary failure. Pressurizer level is low because of the cooldown and it is plausible to think that charging flow can be used to refill the pressurizer, thus requiring entry in ECA-0.1A instead of ECA-0.2A.
C. Incorrect. 1st part is incorrect, but plausible because if the electrical bus was repowered from an emergency diesel generator the SSWP would have been left in AUTO and auto started on the Blackout Sequencer prior to starting the CCWP which would have been placed in PULL-OUT.
However, when the bus is powered from the APG, the CCWP is manually started before the SSWP for bus loading considerations IAW SOP-614A. 2nd part is correct (see D).
D. Correct. 1st part is correct. When the electrical bus is powered from the APG, the correct starting order for the pumps is the CCWP before the SSWP for bus loading considerations. 2nd part is correct. As a result of the cooldown in ECA-0.0A, pressurizer level requires recovery per ECA-0.2A.

Question # 89 Given the following conditions:
0800 Automatic ERCOT grid load shedding removed 25% of grid load and both ERCOT grid and CPNPP main generator frequencies are stable at 58.8 Hz.
At 0802, ABN-601, Response to a 138/345 KV System Malfunction, requires ___(1)___.
Subsequently, per TS 3.8.1, AC Sources - Operating, and OPT-215, Class 1E Electrical Systems Operability, two off-site power sources ___(2)___ remain OPERABLE.
A. (1) tripping both reactors and entering EOP-0.0A/B, Reactor Trip or Safety Injection.
(2) do B. (1) powering both safeguards busses on both Units from the EDGs, with the preferred and alternate feeder breakers placed in PULLOUT.
(2) do C. (1) tripping both reactors and entering EOP-0.0A/B, Reactor Trip or Safety Injection.

(2) do NOT Answer: D Page 57 of 72 CPNPP 2020-05 retake NRC Written Exam Worksheet 81-90 Rev. 3
ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of limitations associated with grid frequency lowering.
SRO Only: SRO Only due to requiring assessment of plant conditions and selecting a procedure to mitigate or recover from the condition, as well as determining the operability of TS equipment.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible (See C). 2nd part is incorrect but plausible as applicant may believe off-site sources remain operable since the breakers were manually disabled due to frequency and could be restored if taken from the PULL-OUT position.
B. Incorrect. 1st part is incorrect but plausible because if still within the 9 minute window plant conditions are maintained to allow for frequency recovery. 2nd part is incorrect, but plausible (See A).
C. Incorrect. 1st part is incorrect, but plausible because per ABN-601 a trip will be required after 9 minutes at <59.4 Hz or if frequency were to drop below 58.4 Hz. 2nd part is correct (see D).
D. Correct. 1st part is correct because ABN-601 requires divorcing the safeguards buses from the grid under these conditions. 2nd part is correct because OPT-215 requires the preferred and alternate supply breakers to the 6.9 KV safeguards buses be either closed or in standby in order for the off-site power sources to be operable.

ES-401 CPNPP 2020-05 retake NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the response needed during a loss of inventory incident during fuel handling preparations.
SRO Only: SRO Only due to requiring assessment of plant conditions and selecting a procedure to mitigate or recover from the condition. Both procedures can be used to raise level, and within each procedure can be used as the method of restoring level, but an assessment must be made based on plant conditions which procedure, and action taken, is the proper selection to be used.
Explanation:
A. Incorrect. 1st part is incorrect, but plausible since this procedure section addresses RCS leakage when the RCS is full if the SRO incorrectly assesses plant conditions and selects this procedure for actions to restore level, but under mid-loop conditions ABN-104 would be the proper selection.
2nd part is correct (see B).
B. Correct. 1st part is correct. With the RCS not filled, the proper procedure used to respond to this event would be ABN-104. 2nd part is correct. Raising charging flow during mid-loop operations is the correct method of raising level with RHR in service.
C. Incorrect. 1st part is correct (see B). 2nd part is incorrect, but plausible since an SI pump would be used in either ABN-104 if the leakage were severe enough that both RHR pumps were required to be secured, or if the SRO incorrectly assesses plant conditions and selects ABN-108 as the proper procedure to respond to this event.
D. Incorrect. 1st part is incorrect, but plausible (see A). 2nd part is correct (see C).
