QUESTIONS REPORT for SRO Exam (2-28) 076 - 008AG2.4.6 001/SRO/T1/G1/3.7/4.7/NEW//

Unit-1 was operating at 100% power when a SGTR occurred on "B" S/G.

  • The crew manually tripped the Reactor and completed 1-E-0 "Reactor Trip or Safety Injection"
  • Both PRZR PORV's are available.
  • Crew is currently depressurizing the RCS to minimize break flow and refill PRZR using 1-RC-PCV-1456 "PRZR PORV".
  • Ruptured S/G pressure is 1035 psig
  • TSC has been activated and has directed using 1-ES-3.1 "Post-SGTR cooldown using backfill" for recovery Current conditions:
  • "B" S/G level = 86% NR
  • PRZR level is 29% and increasing.
  • RCS Pressure is 1034 psig.
  • Crew is stopping the RCS Depressurization when 1-RC-PCV-1456 will not close.
  • While attempting to close 1-RC-MOV-1535, the breaker trips.

Based on Current Conditions the proper procedure transition will be:

A. 1-ECA-3.1 "SGTR with Loss of Reactor Coolant Subcooled Recovery Desired" B. 1-ECA-3.2 "SGTR with Loss of Reactor Coolant Saturated Recovery Desired" C. 1-E-1 "Loss of Reactor or Secondary Coolant" D. 1-ES-3.1 "Post-SGTR Cooldown using backfill" Page 1 of 96

Distractor Analysis:

This requires the examinee to have the knowledge of EOP mitigation strategies as the apply to Pressurizer Vapor Space Accident CORRECT A. 1-ECA-3.1 "SGTR with Loss of Reactor Coolant Subcooled Recovery Desired" Transition to 1-ECA-3.1 from 1-E-3 is made due to the following:

Ruptured S/G not isolated from one intact S/G Ruptured S/G < 350 psig No Intact S/G

< 250 psid between faulted S/G and highest intact S/G RCS subcooling < 45 DEFG PRZR level < 21% with uncontrolled decrease RCS Press Decreasing Nonisolable PZR PORV stuck open INCORRECT B. 1-ECA-3.2 "SGTR with Loss of Reactor Coolant Saturated Recovery Desired" Incorrect but plausible if the SRO candidate is unaware that the only transition to 1-ECA-3.2 "SGTR with Loss of Reactor Coolant Saturated Recovery Desired is from 1-ECA-3.1. There are no direct transitions from 1-E-3. The transition entry conditions from ECA-3.1 is RWST level < 58% or Containment sump level is lower than expected.

or Ruptured S/G level > 90% [85%]

INCORRECT C. 1-E-1 "Loss of Reactor or Secondary Coolant" Incorrect but plausible because the SRO candidate knows that E-1 provides guidance for operating personnel to recover from a loss of reactor or secondary coolant. The question states that the crew went directly from E-0 to E-3 and then the PORV and block valve fails open. The candidate may think the proper transition would be to E-1 to combat the loss of reactor coolant prior to transitioning to an ECA procedure.

INCORRECT D. 1-ES-3.1 "Post-SGTR Cooldown using backfill" Incorrect but plausible if the SRO candidate focus in on the TSC directive to recover using 1-ES-3.1. 1-ES-3.1, 1-ES-3.2, and 1-ES-3.3 are recovery procedures and only transitioned to after 1-E-3 is completed.

Unit 1 was at 100% power when a Loss of all Main Feed Water occurred The crew has just transitioned to 1-ES-0.1, Reactor Trip Response The following indications are noted on PCS:

RCS Tave = 548° F and stable Based on the indications of the attached PCS trend which ONE of the following will the SRO direct the crew to perform?

(Reference provided)

A. Transition to 1-FR-H.1, Response to Loss of Secondary Heat Sink B. Remain in 1-ES-0.1 and perform 1-AP-22.4, Loss of Both Motor-Driven AFW Pumps C. Transition to 1-FR-H.5, Response to Steam Generator Low Level D. Return to 1-ES-0.0, Re-Diagnosis Page 5 of 96

Page 6 of 96 Distractor Analysis:

This requires the examinee to have the ability to use plant computer to evaluate system or component status associated with a Loss of Main Feedwater A. CORRECT Transition to 1-FR-H.1, Response to Loss of Secondary Heat Sink Given the indications showing on the PCS graph, ( AFW Flow to "A" SG At 500 GPM &

"A" SG WR Level Decreasing) AFW is not reaching the A SG and therefore a loss of heat sink is indicated.

B. INCORRECT Remain in 1-ES-0.1 and perform 1-AP-22.4, Loss of Both Motor-Driven AFW Pumps Plausible because if the candidate thinks that the indicated AFW flow is reaching the SG (Based on AFW Flow to "A" SG At 500 GPM) then this would be the required action.

C. INCORRECT Transition to 1-FR-H.5, Response to Steam Generator Low Level Plausible because FR-H.5 conditions are met since all narrow range levels are below 11%.

D. INCORRECT Return to 1-ES-0.0, Re-Diagnosis Plausible because re-diagnosis can be used in many situations after E-0 has been exited but the candidate must know that SI should be in service or required to enter ES-0.0.

1. 078 - 055EA2.03 001/SRO/T1/G1/3.9/4.7/MODIFIED//

Unit 1 was operating at 75% power when a loss of AC power occurred. The following plant conditions exist:

The crew is performing the actions of 1-ECA-0.0 "Loss of All AC Power"

  • The operators completed Step 10 placing various control switches in the Pull-To-Lock position, including the charging pump switches.
  • E Transfer bus is being supplied by the SBO
  • 1J 4160 bus has been restored
  • The Shift Technical Advisor reports a red path still exist on heat sink.

Based on the above information, the crew should ____________ .

A. Proceed to step 31 of 1-ECA-0.0, to facilitate recovery actions.

B. Continue on sequentially with 1-ECA-0.0 from step 11 until transition, to appropriate recovery guildelines.

C. Transition to 1-E-0 "Reactor Trip or Safety Injection", then when directed, transition to 1-FR-H.1 "Response to Loss of Secondary Heat Sink".

D. Complete 1-ECA-0.0, then immediately transition to 1-FR-H.1 "Response to Loss of Secondary Heat Sink".

Distractor Analysis:

This requires the examinee to have the ability to determine or interpret actions necessary to restore power as they apply to a Station Blackout.

A. CORRECT Proceed to step 31 of 1-ECA-0.0, to facilitate recovery actions.

Correct as per the Westinghouse background documents for this caution in ECA-0.0, which is prior to step 10, "To minimize the deterioration of plant conditions, recovery actions should be started as soon as AC power is restored". ECA-0.0 is written such that step 31 can be entered from any step that follows this caution.

B. INCORRECT Continue on sequentially with 1-ECA-0.0 from step 11 until transition to appropriate recovery guildelines.

Incorrect but plausible if the candidate is not familiar with the Caution in 1-ECA-0.0 "When power is restored to any AC emergency bus, then, to facilitate recovery actions, recovery should continue with Step 31. Also, at the beginning of ECA-0.0, there is a Wednesday, January 27, 2016 1:57:56 PM 1 Page 9 of 96

QUESTIONS REPORT for SRO Exam Jan Submittal note "CSF Status Trees should be monitored for information only. FRs should not be implemented".

C. INCORRECT Transition to 1-E-0 "Reactor Trip or Safety Injection", then when directed, transition to 1-FR-H.1 "Response to Loss of Secondary Heat Sink".

Incorrect but plausible if the candidate feels the need to verify equipment and ESF actuation per 1-E-0 after the AC bus is returned to service.

D. INCORRECT Complete 1-ECA-0.0, then immediatly transition to 1-FR-H.1 "Response to Loss of Secondary Heat Sink".

Incorrect but plausible Note in ECA-0.0 "CSF Status Trees should be monitored for information only. FRs should not be implemented". This priority is necessary since all FRGs are written on the premise that at least one ac emergency bus is energized. But in this case the recovery procedure from 1-ECA-0.0 will be either 1-ECA-0.1 "Loss of all AC power Recovery without SI required" which contains a note at the beginning of the procedure "CSF status trees should be monitored for information only. FRs should not be initiated before completion of Step 9" or ECA-0.2 "Loss of all AC power Recovery with SI required" which contains an note at the beginning of the procedure "CSF status trees should be monitored for information only. FRs should not be initiated before completion of Step 11". Actions in guideline ECA-0.0 defeat automatic loading of major plant equipment on the energized AC emergency bus. Steps 1 through 9 of ECA-0.1 starts normal operational equipment as necessary based on plant conditions, and Steps 1 through 11 of ECA-0.2 start safeguards equipment as necessary based on plant conditions. Both of these procedures have priority over the FRGs.

QUESTIONS REPORT for SRO Exam Jan Submittal Comments:

This question matches the K/A statement by requiring the SRO applicant to correctly interpret a set of given plant conditions during a Station Blackout (Loss of All AC Power) casualty, and then determine the appropriate procedure to take actions necessary to mitigate the accident. To arrive at the correct answer, the SRO applicant must recognize that in ECA-0.0 scenario FR procedures are not implemented due to inadequate electrical power situation, and also to recognize the need to jump ahead in the procedure to steps that facilitate recovery actions after power is restored to any AC emergency bus. Also, have knowledge that FRs will be monitored until equipment is started based on plant conditions before FRs become applicable in the recovery procedures that are transitioned to from ECA-0.0 Wednesday, January 27, 2016 1:57:56 PM 4 Page 12 of 96

  • The operating crew can not re-energize 125-volt DC bus
  • VCT level = 20%
  • Pressurizer level > 28%

The SRO will initiate ______(1)_______, and direct the crew to _____(2)_______.

A. (1) 2-AP-49.1 "Loss of Normal and Excess Letdown" (2) Swap Charging suction to RWST B. (1) 2-AP-49 "Loss of Normal Charging" (2) Isolate letdown due to 2-CH-FCV-2122 being closed C. (1) 2-AP-49 "Loss of Normal Charging" (2) Place 2-CH-FCV-2122 in local control at Aux Shutdown Panel and control flow D. (1) 2-AP-49.1 "Loss of Normal and Excess Letdown" (2) Reduce Makeup flow and Maximize RCS sample flow Distractor Analysis:

This requires the examinee to have the ability to interpret and execute procedure steps for Loss of DC power A. INCORRECT (1) 2-AP-49.1 "Loss of Normal and Excess Letdown" (2) Swap Charging suction to RWST Incorrect but plausible, first part is correct, 0-AP-10 "Loss of Power", attachment 19 will direct the crew to initiate 2-AP-49.1 "Loss of Normal and Excess Letdown" If the operating crew can not re-energize 125-volt DC bus 2-III and pressurizer level is greater than 28%, 2-AP-49.1 will then direct the crew to minimize Reactor Coolant System (RCS) makeup flow and to maximize RCS sample flow, to reduce the rate of Pressurizer level increase, because of the Loss of Normal and Excess Letdown.

Second part is incorrect but plausible if the candidate associates the loss of normal and excess letdown to a reduction is VCT level, then swapping to the RWST could be plausible, also the step prior to checking Pressurizer level in 0-AP-10, attachment 9, checks VCT level and if < 15% requires transferring charging pump suction to the RWST.

B. INCORRECT (1) 2-AP-49 "Loss of Normal Charging" (2) Isolate letdown due to 2-CH-FCV-2122 being closed Incorrect but plausible, first part is incorrect; there is not any transitions to 2-AP-49 Wednesday, January 27, 2016 1:57:56 PM 5 Page 13 of 96

QUESTIONS REPORT for SRO Exam Jan Submittal "Loss of Normal Charging" from 0-AP-10. But the candidate may think normal charging is lost due to the DC bus loss and assume that it is the correct procedure for this event.

Second part is incorrect but could be plausible if the candidate does not understand that the signal generated to the E/P for 2-CH-FCV-2122 comes from the process plant cabinet 6, which has two separate power supplies.

C. INCORRECT (1) 2-AP-49 "Loss of Normal Charging" (2) Place 2-CH-FCV-2122 in local control at Aux Shutdown Panel and control flow Incorrect but plausible, first part is incorrect; there are no transitions to 2-AP-49 "Loss of Normal Charging" from 0-AP-10. But the candidate may think normal charging is lost due to the DC bus loss and assumes that it is the correct procedure for this event.

Second part is incorrect but could be plausible if the candidate knows that 2-CH-FCV-2122 can be controlled from the Aux Shutdown Panel and 2-AP-49 does have a step for the operators to use 2-AP-20, Operation from the Auxiliary Shutdown Panel to shift 2-CH-FCV-2122 to local control in the ASP and control charging flow if 2-CH-FCV-2122 demand in not indicated in the control room.

D. CORRECT (1) 2-AP-49.1 "Loss of Normal and Excess Letdown" (2) Reduce Makeup flow and Maximize RCS sample flow Both the first part and second part are correct. 0-AP-10 "Loss of Power", attachment 19 will direct the crew to initiate 2-AP-49.1 "Loss of Normal and Excess Letdown" If the operating crew can not re-energize 125-volt DC bus 2-III and pressurizer level is greater than 28%, 2-AP-49.1 will then direct the crew to minimize Reactor Coolant System (RCS) makeup flow and to maximize RCS sample flow, to Reduce the rate of Pressurizer level increase because of the Loss of Normal and Excess Letdown.

Unit-1 and Unit-2 are both operating at 100% power.

Shortly after midnight, both units are experiencing mega-watt swings along with 500kv bus, voltage and frequency fluctuations.

As per 0-AP-8, Response to Grid Instability, describe the operation of the voltage regulator and when offsite power should be declared inoperable.

A. Place voltage regulators in MANUAL; grid voltage increases to 550 KV B. Maintain voltage regulators in AUTO; grid voltage decreases to 504 KV C. Maintain voltage regulators in AUTO; grid voltage increases to 550 KV D. Place voltage regulators in MANUAL; grid voltage decreases to 504 KV Wednesday, January 27, 2016 1:57:56 PM 9 Page 17 of 96

QUESTIONS REPORT for SRO Exam Jan Submittal Distractor Analysis:

This requires the examinee to have the ability to determine and interpret operational status of offsite circuit as they apply to Generator Voltage and Electric Grid Disturbances.

A) INCORRECT Place voltage regulators in MANUAL; grid voltage increases to 550 KV First part is incorrect but plausible if operator associates mega watt, voltage and frequency swing as a requirement for placing Voltage Regulator in Manual. Note in 0-AP-8 = Fluctuations in Mega-watts indicate grid disturbance, Voltage Regulator failures have little to no affect on mega-watt output. The Voltage Regulators should be kept in AUTO during grid disturbances and has the operator verify Voltage Regulator is in AUTO or place in AUTO if available. Second part is incorrect because high switchyard voltage is NOT an immediate operability concern. The concern is more of a long-term degradation issue for energized equipment, which is covered by a note in 0-AP-8. This is plausible because grid voltage of 550 KV is used as a trigger point in 0-AP-8 to contact System engineer as soon as possible to evaluate GDC-17 requirements and Offsite power source operability.

B) CORRECT Maintain voltage regulators in AUTO; grid voltage decreases to 504 KV First part is correct: Note in 0-AP-8, Fluctuations in Mega-watts indicate grid disturbance, Voltage Regulator failures have little to no affect on mega-watt output.

The Voltage Regulators should be kept in AUTO during grid disturbances and has the operator verify Voltage Regulator is in AUTO or place in AUTO if available. Should the candidate apply 1-AP-26 Failure of Main Generator Voltage Regulator base on voltage swings, then Mega-watts are verified to be stable before the voltage regulator can be placed in Manual. Second part is correct: < 505 KV is the trigger point in 0-AP-8 and 1-LOG-4 to declare offsite power inoperable and enter the applicable actions of T.S.

3.8.1 C) INCORRECT Maintain voltage regulators in AUTO; grid voltage increases to 550 KV Plausible because first part is correct, second part is plausible (see above)

D) INCORRECT Place voltage regulators in MANUAL; grid voltage decreases to 504 KV First part incorrect but plausible (see above), Second part is correct K/A:

Comments:

This question matches the K/A statement by requiring the SRO applicant to analysis and interpretation of operational status of offsite circuit as they apply to Generator Voltage and Electric Grid Disturbances. To arrive at the correct answer the SRO applicant must recognize if the voltage regulator is functioning properly and the condition is due to a perturbation on the grid (MW swing), then the best course of action is to leave the voltage regulator in automatic and allow it to control voltage. Also to possess knowledge of the setpoint that requires declaring the offsite power inoperable.

Distractor Analysis:

This requires the examinee to have the knowledge for adherence to appropriate procedures and operation within the limitations in the facility license and amendments as they apply to the Loss of Secondary Heat Sink.

A) INCORRECT

1) AFW, 2) MFW, 3) RCS bleed and feed, 4) Condensate, 5) Fire Protection or Service Water This could be plausible if the candidate is not familiar with the step that checks if RCS bleed and feed is required, the candidate may think it's appropriate to try and recover flow to S/G using less intrusive sources AFW then MFW before the bleed and feed is started, Condensate and Fire Protection/Service water requires lowering S/G pressure so they would be last.

B) INCORRECT

1) RCS bleed and feed, 2) MFW, 3) Condensate, 4) AFW, 5) Fire Protection or Service Water This could be plausible if the candidate knows that the RCS bleed and feed is required:

(Any 2 S/G wide range level < 14% [24%]). but is not familiar with the correct sequence that the procedure, has AFW, falling into the recovery plan.

C) INCORRECT

1) AFW, 2) MFW, 3) Condensate, 4) Fire Protection or Service Water, 5) RCS bleed and feed.

This could be plausible if the candidate is not familiar with the urgency to start a RCS bleed and feed based on loss of heat sink but is familiar with the order in which the operator attempts to establish flow. (AFW flow, MFW flow, Condensate flow then low pressure water source (FP or SW) in that order)

D) CORRECT

1) RCS bleed and feed, 2) AFW, 3) MFW, 4) Condensate, 5) Fire Protection or Service Water Based on the units stated conditions the following can be established.
1) RCS bleed and feed is required: (Any 2 S/G wide range level < 14%). FR-H.1 is to restore and/or maintain adequate secondary heat removal capability and to establish RCS bleed and feed heat removal if secondary heat removal capability cannot be maintained. This is a continous action step within the procedure and the operators will transition when the proper criteria is met. Then the operator attempts to restore or establish AFW flow, MFW flow, Condensate flow then low-pressure water source (FP or SW) in that order, K/A:

Unit 1 is being returned to 100% power following a scheduled refueling outage.

Reactor power has been stabilized at 50% for shift turnover.

  • RCS Pressure 2235 psia
  • Tavg and Tref are matched
  • Control Rods are in Auto After assuming the duties as the Unit-1 Unit Supervisor, the selected First Stage Pressure channel fails High.

Which one of the following answers list the proper procedure that addresses all the failures of this event and power response to complete the statement?

A. (1) 1-AP-1.1 "Uncontrolled Rod Motion" (2) Decrease B. (1) 1-AP-1.1 "Uncontrolled Rod Motion" (2) Increase C. (1) 1-AP-3 "Loss of Vital Instrumentation" (2) Increase D. (1) 1-AP-3 "Loss of Vital Instrumentation" (2) Decrease Distractor Analysis:

This requires the examinee to have the ability to determine and interpret reactor power and its trend as they apply to continuous rod withdraw.

A) INCORRECT (1) 1-AP-1.1 "Uncontrolled Rod Motion" (2) Decrease First part is incorrect but plausible because when impulse (1st stage pressure) fails high rate of change is sensed by the power mismatch unit and a large Delta is seen between Tavg and Tref. This large temperature error signal and power mismatch error signal are summed and rods will begin to withdraw at maximum speed. At this point candidate may select 1-AP-1.1 because it will address rod motion from a failure within the rod control circuitry. But will not address other parameters controlled by first stage pressure instrumentation. The operators should use 1-AP-3 as the controlling procedure for the loss of vital instrumentation, This will provide the correct response to place rods in manual, control Steam Generator level, and address steam dumps. It also stabilizes, defeats, and corrects the failed indication along with directing the proper T.S requirements. Second part is incorrect but plausible if the candidate thinks rods will insert, attempting to drive first stage pressure down to match Tavg.

The candidate requires the ability to determine and interpret setpoints for alert and high alarms as they apply to the Area Radiation Monitoring (ARM) system alarms.

CORRECT A. Place the fuel building radiation automatic interlock switch in Disable AND Enter (CR) Condition Report; No other action required.

On a HI-HI alarm on 1-RM-RMS-152 or 153 and the key switch in ENABLE position the following will occur: After a 2 minute time delay will automatically dump the MCR bottled air, close the MCR dampers and start the MCR emergency ventilation fans.

D. Transition to 1-FR-Z.1 "Response to High Containment Pressure" Start available recirculation spray pumps.

Distractor Analysis:

Based on Loss of Containment Integrity it requires the candidate to have knowledge of the parameters and logic used to assess the status of safety functions, such as reactivity control, core cooling and heat removal, reactor coolant system integrity, containment conditions, radioactivity release control, etc..

A. INCORRECT Remain in 1-ECA-1.1 "Loss of Emergency Coolant Recirculation" FRs not applicable during 1-ECA-1.1.

Incorrect but plausible because of the beginning note in 1-ECA-1.1 IF Containment Sump Blockage has occurred, THEN FRs should not be implemented until directed in this procedure. If the candidate is not sure of the details, mitigative strategy or has knowledge of this step then this answer may be chosen.

B. CORRECT Transition to 1-FR-Z.1 "Response to High Containment Pressure" Do not start any recirculation spray pumps.

Correct, under the questions given conditions Containment pressure is in the required red path transition path for 1-FR-Z.1 (Containment Pressure > 60 psia and Wednesday, January 27, 2016 1:57:57 PM 21 Page 37 of 96

QUESTIONS REPORT for SRO Exam Jan Submittal Containment sump blockage does not exists). However there is a Caution in 1-FR-Z.1 "If 1-ECA-1.1 Loss of Emergency coolant recirculation, is in effect then to preserve RWST inventory, Step 2 through Step 5 of this procedure should not be performed.

This caution warns the operator that the operation of the containment spray pumps indicated in guideline 1-ECA-1.1 takes precedence. Step 2 through Step 5 of 1-FR-Z.1 Checks if CDA is required, verifies proper operation of Containment quench spray systems, verifies proper operation of the SW system and verifies proper operation of the Containment Recirc spray system. These steps will not be performed based on the Caution.

C. INCORRECT Remain in 1-ECA-1.1 "Loss of Emergency Coolant Recirculation" FRs should not be initiated before completion of step 9 Incorrect but plausible because of the beginning note in 1-ECA-1.1 IF Containment Sump Blockage has occurred, THEN FRs should not be implemented until directed in this procedure. If the candidate is not sure of the details or has knowledge of this step then this answer may be chosen. The statement FRs should not be initiated before completion of step 9 is a requirement listed by a note in 1-ECA-0.1 and is also repeated closely in 1-ECA-0.2 D. INCORRECT Transition to 1-FR-Z.1 "Response to High Containment Pressure" Start available recirculation spray pumps.

Incorrect but plausible because, under the questions given conditions, Containment pressure is in the required red path transition path for 1-FR-Z.1 (Containment Pressure

> 60 psia and Containment Containment sump blockage does not exists). If the candidate does not possess the knowledge of the procedure content in the Caution at the beginning of the procedure "If 1-ECA-1.1 Loss of Emergency coolant recirculation, is in effect then to preserve RWST inventory, Step 2 through Step 5 of this procedure should not be performed", and the candidate is only familiar with the overall mitigative strategy, then this answer could be chosen.

This requires the examinee to have the ability to (a) predict the impacts of faulty or erratic operation of detectors and function generators on the RPS, and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations:

A) INCORRECT Function Protection Overpower Delta-T Reactor Trip Ensures the design limit DNBR is met Function is incorrect but plausible because, TS 3.3.1 Overpower Delta-T is applicable in Modes 1,2 but it does not use Pressurizer Pressure in its calculation like Overtemperature Delta-T does, so it does not require LCO entry Protection is also incorrect but plausible because it would be correct for Overtemperature Delta-T reactor trip B) INCORRECT Function Protection Overtemperature Delta-T Reactor Trip Ensures the integrity of the fuel Function is correct TS 3.3.1 Overtemperature Delta-T setpoints are impacted by RCS pressure and is applicable in Mode 1,2 to place the channel in trip within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

The actions of 0-AP-41 "Severe Weather Conditions" are being performed due to a thunderstorm warning, when lightning strikes the SWYD and a loss of offsite power occurs.

  • 1-ECA-0.0 "Loss of all AC power" was entered.
  • Operations have completed all actions up to determining the correct recovery method and procedure.
  • One AC emergency bus has been energized.
  • RCS subcooling is 35 DEGF.
  • Pressurizer level is 5%.
  • Adverse Containment Conditions do not exist.
  • Safeguards equipment is not operating.

Which answer will complete the following statement?

SRO will direct procedure transition to __________ .

A. 1-ES-0.0 "Re-Diagnosis", to determine or confirm the most appropriate post-accident recovery procedure.

B. 1-ECA-0.1 "Loss of all AC power without SI required", recover the plant based on stable RCS conditions following a lose of all AC power.

C. 1-E-0 "Reactor trip or safety injection", verify proper response of Reactor Protection and safety injection following restoration of at least one emergency bus.

D. 1-ECA-0.2 "Loss of all AC power recovery with SI required" to manually load safeguards equipment as appropriate.

Distractor Analysis:

This requires the examinee to have the ability to (a) predict the impacts of the loss of Instrument bus on the Engineered Safety Features Actuation System (ESFAS); and (b) based on those predictions. use procedures to correct, control, or mitigate the consequences of those malfunction or operations.

A. INCORRECT 1-ES-0.0 "Re-Diagnosis", to determine or confirm the most appropriate post-accident recovery procedure.

Incorrect but plausible because the candidate may decide, since one emergency bus has been recovered, the crew no longer needs to be in the 1-ECA-0 series procedures, and with a low pressurizer level, 1-E-1 should be your recovery procedure and the quickest way is through 1-ES-0.0 "Re-Diagnosis" or 1-ES-0.0 could be used to determine/confirm the most appropriate post-accident recovery procedure the crew should be in. 1-ES-0.0 should only be used when SI is in service or is required and 1-E-0 Reactor Trip or Safety injection has been exited. Based on the given condition entry into the EOP was directly through 1-ECA-0.0 so 1-ES-0.0 can not be used.

Wednesday, January 27, 2016 1:57:57 PM 25 Page 45 of 96

QUESTIONS REPORT for SRO Exam Jan Submittal B. INCORRECT 1-ECA-0.1 "Loss of all AC power without SI required", recover the plant based on stable RCS conditions following a lose of all AC power.

Incorrect but plausible if the candidate reflects only on Subcooling and the fact that one emergency bus has been recovered and safeguards equipment is not operating, but following the restoration of AC power, selection depends on the existence of RCS subcooling 25DEGF [75], existence of pressurizer level > 21% [26], and verification that SI equipment has not automatically actuated upon power restoration. If RCS conditions have not deteriorated significantly (i.e. all criteria satisfied), the operator is directed to guidline ECA-0.1 to recover the plant using normal operational systems.

C. INCORRECT 1-E-0 "Reactor trip or safety injection", verify proper response of Reactor Protection and emergency core cooling systems following restoration of at least one emergency bus.

Incorrect but plausible because the candidate may think that since one emergency bus has been recovered, the crew no longer needs to be in the 1-ECA-0 series procedures and there is a need to verify that the Rx is tripped and initiate SI if required.

D. CORRECT 1-ECA-0.2 "Loss of all AC power recovery with SI required" to manually load safeguards equipment as appropriate.

Correct, 1-ECA-0.0 provides recovery guidelines based on existing RCS conditions.

The criteria for recovery selection includes (1) existence of RCS subcooling (>25 DEGF), (2) existence of Pressurizer level (>21%) and (3) verification that SI equipment has not automatically actuated upon ac power restoration, which would occur if power was restored after SI signal actuation but before SI signal was reset. If any of the criteria is not satisfied the operator is directed to 1-ECA-0.2. This procedure will start safeguards equipment as appropriate and then direct the operator to guideline 1-E-1 "Loss of Reactor or Secondary Coolant, for subsequent recovery actions.

Distractor Analysis:

Ability to (a) predict the impacts of indications and alarms for main steam and area radiation monitors (during SGTR) on the MRSS and (b) based on predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations.

A INCORRECT Isolate AFW to "B" S/G; Contact chemistry and HP for confirmation of the affected S/G prior to initiating 1-E-0, Attachment 8 "Ruptured S/G isolation.

First part is plausible because reducing AFW flow could confirm to the crew that indeed "B" S/G has a tube rupture. The Westinghouse background document mentions "Since primary-to-secondary leakage adds additional inventory which accumulates in the ruptured steam generator, level should return to the narrow range in that steam generator(s) significantly earlier and will continue to increase more rapidly. This Page 49 of 96

response provides confirmation of a steam generator tube rupture event and also identifies the affected steam generator(s)". Second part is also plausible because 1-RM-SV-121 should be showing something and it is not (malfunction); the candidate who does not feel N-16 indication is enough to go on may delay action that are important to limiting offsite dose (attachment 8 isolates steam supply to AFW terry turbine, which is a local action). Also the continuous action page for 1-E-0 (step 7) states Attachement 8 MAY be used, it does not directly instruct the operator to use it.

B INCORRECT Isolate AFW to "B" S/G; Initiate 1-E-0, attachment 8, Ruptured S/G isolation.

First part is plausible because reducing AFW flow could provide the crew with more time before over filling the S/G, but knowledge of Westinghouse background guidelines provides the importance of maintaining the water level above the top of the U-tubes. 1)

Provides Insulation between the ruptured steam generators steam space and the U-tubes. 2) Ensures a heat sink is available if no other intact steam generator is available. 3) Prevents misdiagnosis of the ruptured steam generator due to imbalances in feedwater flow. Second part is correct, attachment 8 should be implemented for identification (which is confirmed by both "B" S/G and Main Steam header N-16 Radiation monitor indication along with a slight decrease of demand on 1-FW-FCV-1488) and isolation which is important to limiting offsite dose.

C INCORRECT Do not isolate AFW to "B" S/G; Contact chemistry and HP for confirmation of the affected S/G prior to initiating 1-E-0, Attachment 8 "Ruptured S/G isolation.

First part is correct need U-tubes covered before isolation. Second part is incorrect but plausible because 1-RM-SV-121should be showing something and it is not (malfunction); the candidate who does not feel N-16 indication is enough to go on may delay action that are important to limiting offsite dose (attachment 8 isolates steam supply to AFW terry turbine, which is a local action.

D CORRECT Do not isolate AFW to "B" S/G; Initiate 1-E-0, Attachment 8, "Ruptured S/G isolation".

First part is correct the Westinghouse background documents Basis describes the requirement to maintain the S/G U-tubes covered before isolation 1) Provides Insulation between the ruptured steam generators steam space and the U-tubes. 2)

Ensures a heat sink is available if no other intact steam generator is available. 3)

Prevents misdiagnosis of the ruptured steam generator due to imbalances in feedwater flow. and second part is correct because attachment 8 should be implemented for identification (which is confirmed by both "B" S/G and Main Steam header N-16 Radiation monitor indication along with a slight decrease of demand on 1-FW-FCV-1488) and isolation which is important to limiting offsite dose.

This question matches the K/A statement by requiring the SRO applicant to have the ability to interpret reference materials, such as graphs, curves, tables, etc. associated with the SW system. On a loss of all service water, component cooling temperatures are expected to increase, with one unit having just been shutdown, RHR in service and the large Decay Heat factor, this will have a large effect on the Spent Fuel Pit temperatures. To arrive at the correct answer the SRO applicant must posses the ability to determine the proper heat up rate of the Spent Fuel Pool based on the ability to use the correct table for the questions given conditions, and then determine the correct heat up rate based on the status of the core. Second the SRO candidate must be able to demonstrate the correct use of the EAL tables to determine the highest EAL classification for the stated conditions.

Unit-1 is at 100%, when Annuciator 1J-G1 "Containment Partial Pressure +0.25 PSI CH I-II", locks in with the following conditions:

  • Partial Pressure Setpoint is set at 10.85 psia on Ch I and II
  • Containment Temperature = 96.0 DEGF Which of the following completes the statement?

Based on these conditions, containment air partial pressure is ____________ for operations AND the limits on pressure and temp ensures that the ___________.

A. Acceptable, Peak containment pressure will be limited to the upper containment pressure of 45 psig B. Unacceptable, Containment pressure will not reach the lower design pressure of 8.6 psia for an inadvertent containment spray actuation.

C. Unacceptable, Peak containment pressure will be limited to the upper containment pressure of 45 psig D. Acceptable, Containment pressure will not reach the lower design pressure of 8.6 psia for an inadvertent containment spray actuation.

Distractor Analysis:

The candidate is required to have the knowledge of conditions and limitations in the facility license as they relate to containment.

A. INCORRECT Acceptable, Peak containment pressure will be limited to the upper containment pressure of 45 psig.

First part is incorrect but is plausible because the partial pressure is given to the candidate as the alarm which is +0.25 PSI greater than the setpoint which is given as 10.85 psia, so the sum of the two (11.1 psia) is the point used on the graph. if the candidate does not add the two then the point will fall in the acceptable region. Second part is the correct limit as per the bases of TS 3.6.4 "Containment Pressure". If the candidate is not familiar with the bases value, it can also be found in section 5.5.15(b)

091 - 015G2.2.25 001/SRO/T2/G2/3.2/4.2/MODIFIED//

Unit-1 status is as follows:

  • A reactor startup is in progress.
  • Both Intermediate Range channels indicate approximately 5 E -11 amps.
  • Source Range Channel N-31 fails low.
  • The Crew initiates 1-AP-4.1 "Malfunction of Source Range Nuclear Instrumentation".

Which One of the following describes (1) the 1-AP-4.1 required response and (2) the Technical Specification Bases for the response?

A. (1) Continue the reactor startup; (2) With only one source range channel operable 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is allowed to restore two channels to service, Protection is provided by the logic of 1/2 SR channels > 10 E 5 cps.

B. (1) Suspend the reactor startup; (2) One decade of overlap between both SR and IR channels cannot be verified.

C. (1) Suspend the reactor startup; (2) With only one source range channel operable, a single random failure will disable the SR Trip function.

D. (1) Continue the reactor startup; (2) Intermediate Range and Power Range low setpoint trip functions provide the necessary redundant protection.

Distractor Analysis:

This requires the examinee to have the knowledge of the bases in Technical Specifications for limiting conditions for operations and safety limits.

A. INCORRECT (1) Continue the reactor startup; (2) With only one source range channel operable 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is allowed to restore two channels to service. Protection is provided by the logic of 1/2 SR channels

> 10 E 5 cps.

The first part is incorrect but plausible if the operator is unfamiliar with the abnormal procdedure guidance associated with the SR failing Low. The Trip Logic is 1/2 SR channels > 10 E 5 cps, so a Rx trip will not occur. The fact that this occurs at < P-6 value (1 X 10 E -10 amps) then the AP checks Reactor power constant, and then restores affected channel to service before exceeding P-6 permissive. Because the procedure does not required inserting rods or opening the Rx trip breakers, it could make this a plausible choice for the candidate. The second part is also incorrect but a plausible choice matched with the first answer because T.S. 3.3.1, Table 3.3.1-1 also list action J as a condition associated with one source range channel inoperable. If the candidate associates this completion time of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> with a Mode 2 requirement then this answer could be matched together with the first part and be chosen. Also combining in the idea that protection is still being provided with the Rx trip logic also makes this a plausble Tech Spec bases choice.

Page 60 of 96

B. INCORRECT (1) Suspend the reactor startup; (2) One decade of overlap between both SR and IR channels cannot be verified.

The first part is correct. The source range trip logic is 1/2 SR channels > 10 E 5 cps, so a Rx trip will not occur. The fact that this occurs at < P-6 value (1 X 10 E -10 amps) then the AP checks Reactor power constant and then restores affected channel to service before exceeding P-6. The second part is incorret but plausible because the start up procedures (OP-1.5 / 1.7) has the operators verify that proper overlap is occuring between the SR and IR instrumentation before maually blocking the Source Range Neutron Flux trip at the P-6 permissive. The candidate may assume this is listed in the bases for the SR intrumentation.

C. CORRECT (1) Suspend the reactor startup; (2) With only one source range channel operable, a single random failure will disable the SR Trip function.

The first part is correct. The source range trip logic is 1/2 SR channels > 10 E 5 cps, so a Rx trip will not occur. The fact that this occurs at < P-6 value (1 X 10 E -10 amps) then the AP checks Reactor power constant and then restores affected channel to service before exceeding P-6. The second part is also correct, The Tech Spec 3.3.1 bases for SR specifies " Two Operable channels are sufficient to ensure no single random failure will disable this Trip function.

D. INCORRECT (1) Continue the reactor startup; (2) Intermediate Range and Power Range low setpoint trip functions provide the necessary redundant protection.

The first part is incorrect but plausible if the operator is unfamiliar with the abnormal procdedure guidance associated with the SR failing Low. The Trip Logic is 1/2 SR channels > 10 E 5 cps, so a Rx trip will not occur. The fact that this occurs at < P-6 value (1 X 10 E -10 amps) then the AP checks Reactor power constant, and then restores affected channel to service before exceeding P-6 permissive. Because the procedure does not required inserting rods or opening the Rx trip breakers, it could make this a plausible choice for the candidate. Second part is incorrect but plausible and could be matched with the first part because the basis associated with SR neutron flux mentions "Above P-6 setpoint, the IR and PR low setpoint trip will provide core protection for reactivity accidents.

This requires the examinee to have the knowledge of radiation monitoring systems, such as fixed radiation monitors and alarms, portable survey instruments, personnel monitoring equipment, etc.

A. INCORRECT (1) 30 (2) 12 First part is incorrect but plausible, If the candidate would consider both N-16 and Page 85 of 96

condenser air ejector radiation monitors non functional at 30% power. As the unit is ramping down, at 30% power 1-SV-RM-121 "Condenser Air Ejector RM" is declared Non-functional, this is described in TRM 3.4.5 bases, "RCS Ar-41 activity is expected to be sufficient to support functionality of the condenser air ejector exhaust system shortly after 30% power is reached. At this point N-16 is still functional and meeting the requirement for the continuous readout radiation monitoring systems.

At NAPs the shutdown procedures then declare N-16 non-functional at 25% power. At that point we do not have a continuous readout radiation monitoring system functional and Condition A will be entered. The second part is incorrect as stated above (SEE plausibility explanation for answer B)

D. CORRECT (1) 25 (2) 4 First part is correct, As the unit is ramping down, at 30% power 1-SV-RM-121 "Condenser Air Ejector RM" is declared Non-functional, this is described in TRM 3.4.5 bases, "RCS Ar-41 activity is expected to be sufficient to support functionality of the condenser air ejector exhaust system shortly after 30% power is reached.

Distractor Analysis:

This requires the examinee to have knowledge of "fire in the plant" procedures.

A. CORRECT (a) Licensed Operator (b) < 15 DEGF/HR (a) Is correct because 1-FCA-2 procedure require the assignment of a Licensed Operator for performing Remote Monitoring operations. (b) is correct, the RCS cooldown limits are posted frequently through out the cooldown sequence and also as a CAUTION of attachment 15 in 1-FCA-2 "Emergency Switchgear Room". 1) With three CRDM fans running cooldown rate is limited to < 25 DEGF/HR 2) With less than three CRDM fans running cooldown rate is limited to < 15 DEGF/HR.

B. INCORRECT (a) Non-Licensed operator who has completed step 7 (b) < 15 DEGF/HR (a) Is incorrect but plausible if the candidate is not sure of the procedure qualification requirements, it would be very likely the candidate would consider a Non-Licensed operator who has completed step 7 as having the qualifications since the operator is not operating equipment and only providing indicated readouts to the control room and also the Fuel Building is a watchstation of a Non-Licensed operators who has completed step 7. Also, a watchstation qualified operator is assigned to perform actions within other FCA series procedures/attachments, example is controlling S/G levels locally in 0-FCA-1 and if remote control of PORV's is not available they can be locally operator by a operator qualified for the watchstation but with constant communication and direction from the MCR such as in attachment 6 in 1-FCA-2. Attachment 15 is the only attachment in 1-FCA-2 out of 17 attachments that requires actions to be performed by a Licensed operator (b) is correct for the questions stated condition that only two CRDM fans are available and running so the cooldown graph that would be chosen for use would be limited to <15 DEGF/HR which is explained by a CAUTION in attachment 15 and posted frequently through out the cooldown sequence of 1-FCA-2.

C. INCORRECT (a) Licensed Operator (b) < 25 DEGF/HR (a) Is correct, 1-FCA-2 procedure requires the assignment of a Licensed Operator for performing remote monitoring operations. (b) is incorrect but plausible if candidate is not sure of FCA requirements vs EOP procedure requirements to determine which cooldown graph to use based on CRDM fans in service, of either < 25 or < 15 DEGF/HR.

D. INCORRECT Page 90 of 96

(a) Non-Licensed operator who has completed step 7 (b) < 25 DEGF/HR (a) Is incorrect but plausible if the candidate is not sure of the procedure qualification requirements, it would be very likely the candidate would consider a Non-Licensed operator who has completed step 7 as having the qualifications since the operator is not operating equipment and only providing indicated readouts to the control room and also the Fuel Building is a watchstation of a Non-Licensed operators who has completed step 7. Also, a watchstation qualified operator is assigned to perform actions within other FCA series procedures/attachments, example is controlling S/G levels locally in 0-FCA-1 and if remote control of PORV's is not available they can be locally operator by a operator qualified for the watchstation but with constant communication and direction from the MCR such as in 1-FCA-3 attachment 10 (b) is incorrect but plausible if candidate is not sure of FCA requirements vs EOP procedure requirements, to determine which cooldown graph to use based on CRDM fans in service, of either <

25 or < 15 DEGF/HR.

Comments:

This question matches the K/A statement by requiring the SRO applicant to possess a working knowledge of NAPs Fire contingency actions (FCA). To arrive at the correct answer the SRO must be aware of the procedure administrative requirement to send a License operator to the fuel building, who in turn will provide remote monitoring to the operators in the MCR or Auxiliary shutdown panel. The SRO must also show knowledge of diagnostic steps and decision point to obtain the proper sub-procedure in terms of selecting the proper cooldown graph.

Unit-2 is defueled with maintenance activities in progress in the Containment Building.

A call comes into the control room that a worker has fallen from a scaffold platform in containment and is unconscious.

  • The crew enters 0-AP-51 "Personnel Injury - Operations Response"
  • The injured worker has various lacerations and abrasions.
  • The First Aid Team determines the worker must be transported to a hospital for treatment.
  • HP survey of the fall area and the workers DAD, indicates no radiological overexposure exist.
  • Some of the workers wounds are contaminated and initial decon efforts have been unsuccessful.

Due to the nature of the injuries a decision is made to immediately transport the worker to the appropriate hospital.

Assuming no news releases or notification to other government agencies are planned, a ___________ notification to the NRC is required in accordance with VPAP-2802, Notifications and Reports, and 10 CFR-50.72.

REFERENCE PROVIDED A. Immediate B. One hour C. Four hour D. Eight hour Page 93 of 96

Distractor Analysis:

The candidate is required to have the knowledge of events related to system operation/status that must be reported to internal organizations or external agencies, such as the State, the NRC, or the transmission system operator.

INCORRECT A. Immediate Incorrect but plausible if the candidate is unfamiliar with using VPAP-2802, and is directed to section 6.3.2 which is plausible if the candidate uses the topic of Personnel overexposures under Radiation or Exposure Events or goes to section 6.28.2 (see above) also the candidate could be directed to section 6.3.2 using Miscellaneous Events or conditions under injuries.

INCORRECT B. One hour Incorrect but plausible if the candidate is unfamiliar with using VPAP-2802, and is directed to section 6.3.3, or goes to section 6.28.2 for internal (Dominion) notification.

This has a step requiring the Manager of Nuclear Operations or Operations Manager on Call to notify the Site Vice President or a director of a potentially media significant event. This step is referenced in section 6.3.5.a.6 and in section 6.2.1(i) bullet for Injuries or accidental deaths or Ambulance transport of personnel to an off-site medical facility.

INCORRECT C. Four hour Incorrect but plausible if the candidate is unfamiliar with using VPAP-2802, and is directed to section 6.3.4 which could be required if a news release is planned CORRECT D. Eight hour The candidate can use section 6.2 of VPAP-2802 "Non-Scheduled Notification and Reports" and search for the matching criteria. In this case section 6.2.1(i)

"Miscellaneous Events or Conditions" (*) Transport of contaminated injured person, and will be directed to step 6.3.5.a.6. Section 6.3.5 is for eight hour notifications; a - As soon as practical, but within eight hours, the Shift Manager shall notify the NRC Operations Center via the ENS of; 6 - Any event requiring the transport of a radioactively contaminated person to an off-site medical facility for treatment.

Question Source: NAPS Vision Bank Question History:

Unit-2 is defueled with maintenance activities in progress in the Containment Building.

During one of these activities, a worker falls form a scaffold ladder. The worker is rendered unconscious and sustains various lacerations and abrasions. The first aid team is dispatched and determines that the worker must be transported to a hospital for treatment. Based on HP survey of the fall area and the workers DAD, no radiological overexposure is suspected, however, it is found that some of the workers wounds are contaminated. Initial efforts to decontaminate the worker on site are not successful further attempts are suspended. Due to the nature of the injuries, a decision is made to immediately transport the worker to the appropriate hospital. The worker arrives at the hospital by ambulance within the next hour to receive further medical treatment.
