ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring ability to determine the amount of subcooling in the pressurizer using steam tables.

Explanation:

A. Incorrect. First part is incorrect, but plausible since this value would be obtained if 335 psig is converted incorrectly to a value of 320 psia which has a saturation temperature of 423oF. Second part is correct (see C).

B. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible since this is the dynamics that occur on an outsurge and not an insurge.

C. Correct. First part is correct. 335 psig is equivalent to approximately 350 psia and saturation temperature for this pressure is approximately 432oF. With temperature indication of 400oF, it is subcooled by 32oF. Second part is correct. A pressure rise from an insurge into the Pressurizer is limited by steam condensing into liquid.

D. Incorrect. First part is correct (see C). Second part is incorrect, but plausible (see B).

A. Battery BT1ED2 voltage is 125 VDC B. Battery BT1ED3 float current is 0 amps C. Battery Charger BC1ED1-1 EQUALIZE push button is depressed D. Battery Charger BC1ED4-1 is placed under clearance after placing Battery Charger BC1ED4-2 in service Answer: A Page 29 of 63 CPNPP 2021-08 NRC Written Exam Worksheet 11-20 Rev. 3

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of TS entry conditions for DC electrical systems.

Explanation:

A. Correct. Each battery is required to have a minimum float voltage of 2.13 volts per cell or 128 volts total.

B. Incorrect. Plausible since 0 amps may indicate that the battery is not performing its function, but a float current of 0 amps indicates that the battery charger has fully charged the battery and the battery charger is supplying all bus loads.

C. Incorrect. Plausible since battery charger BC1ED1-2 is already out of service, but depressing the equalize push button causes battery charger output voltage to be 138 - 140 VDC which is an operable condition.

D. Incorrect. Plausible since one battery charger is already out of service, but BC1ED4-1 is a different train and BC1ED4-2 would be placed in service prior to placing BC1ED4-1 under clearance.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of radiation monitor trends following actions taken due to high radiation levels.

Explanation:

A. Incorrect. First part is incorrect, but plausible since lowering load causes less steam flow to leave steam line, so it could be thought that leakage is being contained in area of rad monitor causing an increase. Second part is incorrect, but plausible (see C).

B. Correct. First part is correct. As power lowers for the same size leak the trend decreases due to less activity. Second part is correct. When the MSIV is closed no flow goes past the rad monitor so the rad monitor decreases back towards normal.

C. Incorrect. First part is correct (see B). Second part is incorrect, but plausible since it could be thought that containing all the leakage upstream of the MSIV after it is closed will cause rad levels to increase.

D. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible (see C).

Explanation:

A. Correct. In accordance with IPO-010B, Attachment 1, the containment hatches must be closed upon a loss of RHR and before core boiling occurs.

B. Incorrect. Plausible because placing the RCS under vacuum has an increased potential to introduce level instrument errors and possibly lead to RHR pump cavitation. Incorrect as SOP-101B maintains requirements to be capable of closing the equipment hatch during vacuum fill operations.

C. Incorrect. Plausible because RHR Cold Leg Injection Valve throttling only occurs when RCS level is lowered below 56 above core plate. The throttling is performed in response to CPNPP flow data which indicates an increased probability of air introduction via vortexing into the RHR pump suctions. Incorrect as IPO-010B does not require any additional closure requirements prior to throttling injection flow.

D. Incorrect. Plausible because this defines the transition to reduced inventory operation at CPNPP.

Incorrect, as hatch does not to be installed, but preparations must be complete to allow installation.

Explanation:

A. Incorrect. First part is incorrect since the valves close upon the opening of the CS HX outlet valves, but plausible since the valves will not open on an SI or CS actuation signal directly.

Second part is correct (see D).

B. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible since CS signal may be reset prior to going to recirculation, but valve operation is based on position of CS HX outlet or sump recirculation valve position.

C. Incorrect. First part is correct (see D). Second part is incorrect, but plausible (see B).

D. Correct. First part is correct. These recirc valves are normally in automatic and close automatically when the CS HX outlet valve opens on the CS actuation signal. Second part is correct. When the containment spray system is aligned for recirculation the valves will remain closed due to the heat exchanger outlet valves open, as well as the sump suction valves being opened.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the effect of an RCP trip on SG level and the reactor.

Explanation:

A. Incorrect. First part is correct. The RCP trip causes less heat input to the SG, so level drops due to shrink as the SG stops steaming. Second part is incorrect, but plausible if the setpoint for P-8 is incorrectly applied knowledge which might lead to think that an automatic reactor trip should occur.

B. Correct. First part is correct (see A). Second part is correct. Even though the automatic reactor trip on single loop low flow is enabled only above P-8, a manual reactor trip is required per procedure.

C. Incorrect. First part is incorrect, but plausible since shrink and swell is a commonly misunderstood aspect of steam generator level response, and it is reasonable for an applicant to be confused and reverse the response. Second part is incorrect (see A).

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the P-7 interlock associated with pressurizer high water level reactor trip.

Explanation:

A. Correct. Pressurizer high level trip is enabled above P-7 which receives an input from P-10 or P-

13. Either first stage turbine pressure above 10% turbine load provides the at power condition for the turbine, providing P-13, and thus P-7, enabling the high level trip.

B. Incorrect. Plausible since either first stage turbine pressure will give P-13 and P-7, but the failure low will not cause the turbine to be at power, although it may be confused because the associated PCIP window comes on when power is below 10%.

C. Incorrect. Plausible since PR NIS input to P-10 which provides P-7, but the coincidence for P-10 is 2/4 above 10% power.

D. Incorrect. Plausible since PR NIS input to P-10 which provides P-7, but the coincidence for P-10 is 2/4 above 10% power, although it may be confused because the associated PCIP window comes on when power is below 10%.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of how an inaccuracy in the calorimetric calibration affects the indication of power range channels.

Explanation:

A. Incorrect. First part is incorrect, but plausible since green is the color used for many indications, such as breakers open and valves closed. Second part is correct (see C).

B. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible (see D).

C. Correct. First part is correct. A red check mark indicates that the LEFM is not available to be used and the feedwater venturis should be used. Second part is correct. Using a lower feedwater temperature indicates that more heat must be added to the feedwater to raise it to saturation due to having a lower enthalpy, so the indicated power will be greater than actual power.

D. Incorrect. First part is correct (see C). Second part is incorrect, but plausible if thought that lower feedwater temperature used would cause the actual power to be greater than indicated.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of how a failure of a detector effects pressurizer level control system.

Explanation:

A. Correct. 1st part is correct. As level in the reference leg lowers, DP will lower. In the Przr level detector, this will result in indicated Przr level rising. FCV-0121 will throttle close in an attempt to reduce Przr level. 2nd part is correct. LT-461 is the only option as a substitute for LT-459. LT-462 is cold calibrated and used for indication only.

B. Incorrect. 1st part is correct (see A). 2nd part is incorrect because LT-461 is the only option as a substitute for LT-459. It is plausible because there are 4 pressure transmitters for Pressurizer pressure with each channel having its own standby transmitter. Level is different in that there is only one back which can be substituted for either LT-459 or LT-460.

C. Incorrect. 1st part is incorrect because a leak in the reference leg will cause FCV-0121 to close due to indicated Przr level rising. It is plausible because the effects of a reference leg leak are commonly mistaken. 2nd part is correct (see A).

D. Incorrect. 1st part is incorrect but plausible (see C). 2nd part is incorrect but plausible (see B).

D. tripping SFP Cooling Water Pump X-02 on a low level in X-01 Spent Fuel Pool.

Answer: A Page 17 of 47 CPNPP 2021-08 NRC Written Exam Worksheet 31-40 Rev. 2

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the function of the anti-siphon holes on the discharge piping located in the SFPs.

Explanation:

A. Correct. The pump must first lose suction, with no discharge pressure the SFP water will backflow through the discharge piping until the anti-siphon hole is uncovered.

B. Incorrect. Plausible based on the location of the leak once the pump loses suction water will continue to drain out the SFP until the anti-siphon hole is uncovered on the discharge piping.

C. Incorrect. Plausible since a discharge check valve would prevent backflow, but the check valve is upstream of the discharge valve and would have no effect if the leak is downstream.

D. Incorrect. Plausible because the pump will trip on low level in its associated SFP.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the steam dump system controls when operating in the steam pressure mode.

Explanation:

A. Incorrect. Plausible since all valves close below P-12 until bypass is selected and then only the Bank 1 valves can open.

B. Correct. Bypassing the P-12 interlock allows the Bank 1 valves to open. With demand at 50%,

the Bank 1 valves will be fully open (at 25%), all others are prevented from opening.

C. Incorrect. Plausible since Bank 1 and Bank 2 valves have an open signal, but only the Bank 1 valves can be opened below P-12.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the actions taken in the event of the MTG fails to trip when required.

Explanation:

A. Incorrect. First part is incorrect because EOP-0.0 step 2 RNO states that if the turbine will not trip, THEN pull-out all EHC fluid pumps. It is plausible because if this step is unsuccessful, it then directs closing the MSIVs. Second part is incorrect because the reason for tripping the turbine is to stop the cooldown which would add positive reactivity and possibly initiate SI. It is plausible because analysis during an ATWT has shown that a turbine trip is necessary within 30 seconds to conserve SG inventory.

B. Incorrect. First part is incorrect, but plausible (see A). Second part is correct (see D).

C. Incorrect. First part is correct (see D). Second part is incorrect, but plausible (see A).

D. Correct. First part is correct. Turbine is tripped by placing EHC pumps in pullout. Second part is correct. The reason for tripping the turbine on a Reactor Trip is to prevent excessive RCS cooldown.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the actions to be taken in the event of a loss of all circ water pumps.

Explanation:

A. Correct. First part is correct. With reactor power above 10%, the reactor is to be tripped.

Second part is correct. With no circ water pumps available, the condenser is not available for steam dumps so the MSIVs are closed to control steam demand with the ARVs.

B. Incorrect. First part is correct (see A). Second part is incorrect, but plausible (see D).

C. Incorrect. First part is incorrect, but plausible (see D). Second part is correct (see A).

D. Incorrect. First part is incorrect, but plausible since for all other conditions only a turbine trip is required up to P-9, 50% power. Second part is incorrect, but plausible since MSIVs are typically left open following a reactor or turbine trip.

A. Correct. First part is correct. A check is made on RCS pressure to determine if it is decreasing or stable. If decreasing, it is either due to an RCS LOCA or due to a SG fault that has not yet completed blowing down. Second part is correct. If RCS pressure is decreasing or stable, a check is made on SG pressure to determine if the decrease in RCS pressure is due to the SG fault still blowing down. If the SG pressure is stable or increasing, this is an indication that the SG fault has completed blowing down if it existed. If a SG fault was the cause of the entry to EOP-1.0A, RCS pressure would be increasing after the SG blows down.

B. Incorrect. First part is correct (see A). Second part is incorrect, but plausible since SG pressure may continue to lower if the SG is not completed blowing down.

C. Incorrect. First part is incorrect, but plausible since RCS pressure could be stable or increasing if the SG has completed blowing down. Second part is correct (see A).

D. Incorrect. First part is incorrect, but plausible (see C). Second part is incorrect, but plausible (see B).

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of indications of natural circulation flow flowing a loss of all RCPs.

Explanation:

A. Incorrect. First part is incorrect, but plausible since the RCS must be subcooled by more than 25oF, but that is based on RCS pressure, not SG pressure. Second part is correct (see C).

B. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible since changing SG pressure could enhance natural circulation, but by lowering it due to increasing steaming rate.

C. Correct. First part is correct. To support indication of natural circulation, RCS cold leg temperatures should be at saturation temperature for SG pressure, so cold leg temperature being 9oF above saturation is indication that natural circulation does not exist. Saturation temperature for 1047 psig is 552F. Second part is correct. Raising SG level adds cold water to the SG, increasing the difference in temperature between the heat source and heat sink, increasing the likelihood of natural circulation.

D. Incorrect. First part is correct (see C). Second part is incorrect, but plausible (see B)

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the actions to be taken in the event of a loss of SSW.

Explanation:

A. Incorrect. First part is incorrect, but plausible because the BOS will fire to load the EDG and the SSW Pump will have an amber MISMATCH light until the sequencer sends a signal to start the pump, however, the white TRIP light is not expected and this is an indication that the pump has tripped and will not start on the sequencer timing. The immediate action per ABN-501 is to place the EDG in PULLOUT. Second part is correct (see D).

B. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible since the unit would be tripped if both buses were lost.

C. Incorrect. First part is correct (see D). Second part is incorrect, but plausible (see B)..

D. Correct. First part is correct. With the SSW Pump tripped, the EDG must be immediately tripped whether or not it is carrying the bus. Second part is correct. A loss of a single Safeguards Bus does not require the Unit be tripped.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of loss of coolant recirc procedures to obtain desired results.

Explanation:

A. Incorrect. First part is incorrect, but plausible since this would provide maximum makeup to RCS, but conflicts with objective to conserve RWST inventory. Second part is incorrect, but plausible as the Steam Dumps would be used if the condenser was available and it was not recognized that a MSL isolation occurred due to Containment Pressure.

B. Incorrect. First part is incorrect, but plausible (see A). Second part is correct (see D).

C. Incorrect. First part is correct (see D). Second part is incorrect, but plausible (see A).

D. Correct. First part is correct. Minimizing subcooling while cooling down ensures that the RCS is at the minimum pressure allowable while still maintaining the RCS subcooled.

This minimizes RCS break flow and thereby minimizes the amount of makeup flow required to the RCS. Second part is correct. Condenser is not available so the ARVs must be used.

SRO Only: SRO Only due to 10 CFR 55.43(b)(2) Analysis requiring knowledge of TS bases that is required to analyze TS-required actions and terminology.

Explanation:

A. Correct. First part is correct. Pressurizer pressure provides both control and protection functions and actuation logic must be able to withstand both an input failure to control system, and a single failure in the other channels providing the protection function actuation. Thus, four channels are required to satisfy the requirements with a two-out-of-four logic. Second part is correct. This is one of the only functions that requires the bistable output to energize to perform its required action. Four channels are used in a two-out-of-four logic configuration because this function is energize to trip.

B. Incorrect. First part is correct (see A). Second part is incorrect, but plausible if thought that reason for pressurizer pressure logic also applied to high-3 logic.

C. Incorrect. First part is incorrect, but plausible if thought that pressurizer pressure was energized to actuate. Second part is correct (see A).

D. Incorrect. First part is incorrect, but plausible (see C). Second part is incorrect, but plausible (see B).

SRO Only: SRO Only due to 10 CFR 55.43(b)(5) Analysis requiring knowledge of the content of the procedure versus knowledge of the procedures overall mitigative strategy or purpose.

Explanation:

A. Incorrect. Plausible since CS is to be secured and it is desirable to restore some form of containment cooling and a step in the procedure directs restarting the coolers, but only if pressure has remained below 5 psig.

B. Incorrect. Plausible since CS is to be secured and pressure must be below 5 psig to operate the fan coolers and a step in the procedure directs restarting the coolers, but it must have remained below 5 psig for the duration of the event otherwise a Plant Staff evaluation is required prior to starting the coolers.

C. Incorrect. Plausible since CCW flow must be verified to the Chillers or they cannot be started, but there is no reason to think that CCW flow cannot be restored.

D. Correct. With containment pressure above 5 psig, the cooling water for the containment coolers may be saturated and water hammer may occur in the system if chill water is restored.

ES-401 CPNPP 2021-08 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 a Condensate Pump will have on the plant.

SRO Only: SRO Only due to 10 CFR 55.43(b)(2) Analysis requiring application of required actions (TS Section 3) and SRs (TS Section 4) in accordance with rules of application requirements (TS Section 1) and 10 CFR 55.43(b)(5) Analysis requiring assessment of plant conditions (normal, abnormal, or emergency) and then selection of a procedure or section of a procedure to mitigate or recover, or with which to proceed.

Explanation:

A. Incorrect. First part is incorrect, but plausible (see B). Second part is incorrect, but plausible (see C).

B. Incorrect. First part is incorrect, but plausible since it is desirable to have T-ave matched to T-ref, but driving control rods in this far will result in an overshoot low on temperature. Additionally, automatic rod control would insert rods until 1ºF mismatch. Second part is correct (see D).

C. Incorrect. First part is correct (see D). Second part is incorrect, but plausible since many more TS actions are 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> requirements than 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> requirements.

D. Correct . First part is correct. When driving rods manually following a runback or other large load reduction, good technique would be a continuous insertion until temperature is approximately 5 degrees high. This ensures a timely reduction in steam flow (via steam dumps) while preventing an overshoot low on temperature. Second part is correct. Rods are to be restored above RIL within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the content of procedures related to fires in the Control Room or cable spreading room.

SRO Only: SRO Only due to 10 CFR 55.43(b)(5) analysis involves both (1) assessing plant conditions (normal, abnormal, or emergency) and then (2) selecting a procedure or section of a procedure to mitigate or recover, or with which to proceed. One area of SRO-level knowledge (with respect to selecting a procedure) is knowledge of the content of the procedure versus knowledge of the procedures overall mitigative strategy or purpose.

Explanation:

A. Incorrect. First part is incorrect, but plausible since a cooldown via the steam dumps is normally preferred over using the ARVs. Second part is correct. ABN-803A contains a note that once the decision to evacuate the control room is made, ERGs are no longer applicable.

B. Incorrect. First part is incorrect, but plausible (see A). Second part is incorrect, but plausible because if control room evacuation was not performed, the natural circulation cooldown would be performed per the guidance of EOS-0.2A.

C. Correct. First part is correct. Any plant cooldown performed from outside the control room is performed using the SG ARVs. Second part is correct (see A).

D. Incorrect. First part is correct (see C). Second part is incorrect, but plausible (see B).

An Anticipated Transient Without Trip (ATWT) event is in progress on Unit 1.

FRS-0.1A, Response to Nuclear Power Generation/ATWT, is in progress and the Reactor is still NOT tripped.

Boration CANNOT be initiated because of blockage in the Boration flowpaths.

All Power Range Channels indicate 6%.

Startup rate is zero on both Intermediate Range Channels.

Average Core Exit Thermocouple temperature is 580°F and slowly lowering.

Which of the following describes the operator actions under these conditions and the reason for taking these actions?

A. Exit FRS-0.1A because the zero startup rate on the Intermediate Range channels indicate actions taken in FRS-0.1A have been successful B. Remain in FRS-0.1A, and allow the RCS to heat up, adding negative reactivity, while continuing efforts to establish Emergency Boration C. Exit FRS-0.1A because the lowering CET temperatures indicate actions taken in FRS-0.1A have been successful D. Remain in FRS-0.1A, and lower RCS temperature, establishing DNBR margin, while continuing efforts to establish Emergency Boration Answer: B Page 21 of 73 CPNPP 2021-08 NRC Written Exam Worksheet 81-90 Rev. 3

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of the actions taken in response to an ATWT condition.

Explanation:

A. Incorrect. Plausible since a zero startup rate would not meet the entry conditions for FRS-0.1A if power ranges were below 5% so it could be considered that exit conditions are met.

B. Correct. Exit conditions have not been met in FRS-0.1A, as power range is still above 5%. While attempting establish boration, the RCS is allowed to heat up to add negative reactivity.

C. Incorrect. Plausible since a there is a transition from FRS-0.1 based on CET temperatures, though it is to SAMGs on high temperature.

D. Incorrect. First part is incorrect, but plausible as conditions to exit FRS have not been met.

Second part is incorrect, but plausible since it is a true statement but has no bearing on the performance of FRS-0.1A.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of abnormal condition procedures which contain the guidance for restoring power to a Vital AC Instrument Bus and the associated Technical Specification.

SRO Only: SRO Only due to 10 CFR 55.43(b)(2) Analysis requiring application of required actions (TS Section 3) and SRs (TS Section 4) in accordance with rules of application requirements (TS Section 1).

Explanation:

A. Correct. First part is correct. In accordance with ABN-603, the US will direct an operator in the field to energize 2EC1 via its alternate power supply, 2EC3, by sliding the manual transfer switch to the alternate position at the bottom of the instrument panel. Second part is correct. In accordance with TS 3.8.9, Condition 'B', the AC Vital bus subsystem will be restored to OPERABLE status within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. Per TS 3.8.9 Bases re-energizing Instrument Panel 2EC1 via its alternate power supply will restore it to OPERABLE status.

B. Incorrect. First part is correct (see A). Second part is incorrect, but plausible as TS 3.8.9 Condition 'A' requires an AC electrical power distribution subsystem to be restored within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

Condition 'A' applies to 6900V and 480V distribution subsystems and is commonly confused with Condition 'B'.

C. Incorrect. First part is incorrect, but plausible since the next step of ABN 603 is to initiate actions to place the swing inverter, IV2EC1/3, in service. However, this must be performed per SOP-607B and will take some time to perform. Per TS 3.8.9 Bases re-energizing Instrument Panel 2EC1 via the swing inverter will also restore it to OPERABLE status. Second part is correct (see A).

D. Incorrect. First part is incorrect, but plausible (see C). Second part is incorrect, but plausible (see B).

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring the ability to determine the selection of appropriate procedures during a LOCA outside containment.

SRO Only: SRO Only due to 10 CFR 55.43(b)(5) Analysis involving both 1) assessing plant conditions (normal, abnormal, or emergency) and then 2) selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed, including knowledge of the content of the procedure versus knowledge of the procedure's overall mitigative strategy or purpose.

Explanation:

A. Incorrect. First part is correct. These valves are normally open, so you are directed to close them and check RCS pressure to see if the leak has stopped. Second part is incorrect, but plausible since a loss of reactor coolant exists. If the leak has not been stopped, you are directed to GO TO ECA-1.1A.

B. Correct. First part is correct (see A). Second part is correct. If the leak still exists, you are directed to GO TO ECA-1.1A.

C. Incorrect. First part is incorrect, but plausible since these valves are verified closed. They are normally closed so it would not be prudent to open them to check for a leak. Second part is incorrect, but plausible (see A).

D. Incorrect. First part is incorrect, but plausible (see C). Second part is correct (see B).

A. Incorrect. First part is correct (see B). Second part is incorrect, but plausible since actions taken during startup, if the startup is aborted, are to insert control bank rods to CBO and shutdown rods do not have a CBO position.

B. Correct. First part is correct, the lowering SRHV causes less interactions between the core and the BF3 detector, causing counts to lower. Second part is correct. Per TS 3.3.1, if the inoperable SR is not returned to operable status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, all rods, both control bank and shutdown bank rods, must be fully inserted.

C. Incorrect. First part is incorrect, but plausible if thought SRHV supplied compensating voltage, as is done in the IR channels, which would then cause counts to increase upon the loss. Second part is incorrect, but plausible (see A).

D. Incorrect. First part is incorrect, but plausible (see C). Second part is correct (see B).

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of cautions stated in procedure ECA-3.2.

SRO Only: SRO Only due to 10 CFR 55.43(b)(5) Analysis requiring assessment of plant conditions (normal, abnormal, or emergency) and then selection of a procedure or section of a procedure to mitigate or recover, or with which to proceed. Also requires knowledge of diagnostic steps and decision points in the emergency operating procedures (EOPs) that involve transitions to event-specific sub-procedures or emergency contingency procedures.

Explanation:

A. Incorrect. Plausible because normally YELLOW path procedures are addressed at the discretion of the US, but CORE COOLING actions conflict with ECA-3.2 actions and should not be performed.

B. Incorrect. Plausible because CORE COOLING actions conflict with ECA-3.2 actions and should not be performed, but INVENTORY actions could be taken.

C. Incorrect. Plausible since actions from one of these procedures is not to be performed due to conflicts with ECA-3.2 actions, but the conflicting procedure addresses CORE COOLING.

D. Correct. Per the guidance contained in FRC-0.3A, Response to Saturated Core Cooling. FRC-0.3A directs a reestablishment of RCS subcooling via Safety Injection Flow. This is inconsistent with the actions of ECA-3.2A which reduce RCS subcooling via ECCS flow reduction in order to minimize primary to secondary leakage during a SGTR.

Answer: D Page 39 of 60 CPNPP 2021-08 NRC Written Exam Worksheet 91-100 Rev. 2

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of surveillance procedure administrative requirements.

SRO Only: SRO Only due to 10 CFR 55.43(b)(2) Analysis requiring knowledge of generic LCO requirements (LCO 3.0.1 through 3.0.7 and SR 4.0.1 through 4.0.4).

Explanation:

A. Incorrect. Plausible since 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> would be the time frame if the surveillance period were less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, but the greater interval is permitted.

B. Incorrect. Plausible since the surveillance is used to determine operability, but the LCO does not need to be implemented until the extended time as granted by SR 3.0.3 expires.

C. Incorrect. Plausible since the surveillance is used to determine operability, but SR 3.0.3 permits delaying the surveillance.

D. Correct. If it is discovered that a Surveillance was not performed within its specified Frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified Frequency, whichever is GREATER. This delay period is permitted to allow performance of the Surveillance.

Date: Rev. 1 Tier 3 Group K/A 2.3.13 Level of Difficulty: 2 Importance Rating 3.8 Knowledge of radiological safety procedures pertaining to licensed operator duties, such as response to radiation monitor alarms, containment entry requirements, fuel handling responsibilities, access to locked high-radiation areas, aligning filters, etc.

Question # 98 A clearance is to be installed with the following conditions:

Contact radiation on a piece of equipment is 5 R/hr Radiation level is 500 mrem/hr at 1 foot from the piece of equipment General area radiation for the room is 125 mrem/hr An operator must close and place a clearance tag on a valve which is located 8 feet away from the equipment It will take the operator 3 minutes to close the valve and place the clearance tag The proper classification for the room is __(1)__.

A waiver of the independent verification of the tag placement is __(2)__ by the Shift Manager.

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring knowledge of radiological safe practices to minimize total exposure to personnel and authority of Shift Manager regarding waivers due to radiation levels.

SRO Only: SRO Only due to 10 CFR 55.43(b)(4) Analysis requiring analysis and interpretation of radiation and activity readings as they pertain to the selection of administrative, normal, abnormal, and emergency procedures.

Explanation:

A. Incorrect. First part is correct (see D). Second part is incorrect, but plausible (see B).

B. Incorrect. First part is incorrect, but plausible since a radiation area is defined as an area where an individual can receive a dose equivalent in excess of 5 mrem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> at 30 cm (12 inches) from the radiation source, but being in excess of 100 mrem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> upgrades the classification to a High Radiation Area. Second part is incorrect, but plausible since the total dose that the operator will receive is below threshold of 10 mrem to waive (dose received will be approximately 2.6 mrem total), however dose rate is sufficient to allow waiver.

C. Incorrect. First part is incorrect, but plausible (see B). Second part is correct (see D).

D. Correct. First part is correct. A high radiation area is defined as an area where an individual can receive a dose equivalent in excess of 100 mrem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> at 30 cm (12 inches) from the radiation source. Second part is correct. The dose rate of >100 mrem/hr allows this verification be waived. .halving the distance from a point source causes the intensity to increase by a factor of four. , although total exposure for verification is 8 mrem (160 mrem/hr for 3 minutes, 1/20th of hour), the dose rate of >100 mrem/hr allows this verification be waived.

Question # 99 Given the following conditions:

The crew is responding to a large break LOCA A CORE COOLING status tree ORANGE path causes a transition to FRC-0.2A, Response to Degraded Core Cooling.

During performance of FRC-0.2A, the CORE COOLING status tree changes from ORANGE to YELLOW.

An ORANGE path exists on the CONTAINMENT status tree.

FRZ-0.1A, Response to High Containment Pressure, is the procedure referenced by the CONTAINMENT status tree.

Which of the following is the required action?

A. Complete FRC-0.2A and then go to FRZ-0.1A since CONTAINMENT is a lower priority path than CORE COOLING.

B. Go to FRZ-0.1A since an ORANGE path has a higher priority than a YELLOW path.

Completion of FRC-0.2A is NOT needed.

C. Complete FRC-0.2A as entry into FRZ-0.1 is NOT needed since it would have been addressed by the performance of steps in EOP-1.0A.

D. Go to FRZ-0.1A since an ORANGE path has a higher priority than a YELLOW path.

Return to complete FRC-0.2A after FRZ-0.1A is addressed.

Answer: A Page 49 of 60 CPNPP 2021-08 NRC Written Exam Worksheet 91-100 Rev. 2

ES-401 CPNPP 2021-08 NRC Written Exam Worksheet Form ES-401-5 K/A Match: K/A match due to requiring the ability to prioritize safety functions during an event.

SRO Only: SRO Only due to 10 CFR 55.43(b)(5) Analysis requiring knowledge of administrative procedures that specify hierarchy, implementation, and/or coordination of plant normal, abnormal, and emergency procedures.

Explanation:

A. Correct. Upon entry to a RED or ORANGE path FRG, the procedure is performed to completion unless a higher RED or ORANGE path procedure is encountered, even if the path clears or becomes YELLOW before completion. Since CORE COOLING is a higher priority than CONTAINMENT, FRC-0.2 is completed before FRZ-0.1 is addressed.

B. Incorrect. Plausible since if these conditions had been identified prior to entering FRC-0.2, then FRZ-0.1 would be the higher priority, but incorrect since FRC-0.2 is to be completed even though it has turned YELLOW.

C. Incorrect. Plausible since entry into FRZ-0.1 would not be required if the steps were performed in EOP-1.0 and an ORANGE path did not exist. The crew would enter FRZ-0.1 and immediately transition out at Step 1 in this case.

D. Incorrect. Plausible since if these conditions had been identified prior to entering FRC-0.2, then FRZ-0.1 would be the higher priority, but incorrect since FRC-0.2 is to be completed even though it has turned YELLOW.
