ES-401 Sample Written Examination Form ES-401-5 Question Worksheet 34K/A Number: 002G2.2.25, Reactor Coolant / 2, Knowledge of the bases in Technical Specifications for limiting conditions for operations and safety limits.
Level: SRO Tier #: 2 Group #: 2 IR - RO: 3.2 IR-SRO: 4.2 Proposed Question: !76 Given the following:
- Unit 1 is cooling down for refueling outage.
- RCS Tave is 349 oF.
- RCS Pressure is 360 psig.
Which ONE of the following correctly states:
- 1) The maximum number of charging pumps that are allowed per Tech Specs 3.1.G, RCS Overpressure Mitigation for sustained operation.
- 2) The basis for that requirement?
A. 1. one charging pump capable of injecting into the RCS.
- 2. To ensure that the mass addition transient, can be relieved by the operation of a single PORV or equivalent.
B. 1. one charging pump capable of injecting into the RCS.
- 2. To ensure that the mass addition transient, can be relieved by the operation of both PORVs, or equivalent.
C. 1. two charging pumps capable of injecting into the RCS.
- 2. To ensure that the mass addition transient, can be relieved by the operation of both PORVs, or equivalent.
D. 1. two charging pumps capable of injecting into the RCS.
- 2. To ensure that the mass addition transient can be relieved by the operation of a single PORV, or equivalent.
Proposed Answer: A Explanation: Part 1) Technical Specifications 3.1.G.c.(1) states: Whenever the RCS average temperature is less than or equal to 350 oF and the reactor vessel head is bolted: A maximum of one charging pump shall be OPERABLE and capable of injecting into the RCS. Two charging pumps may be in operation momentarily during transfer of operation from one charging pump to another. The question asks for the requirement for sustained operation therefore a maximum of one charging pump is the only correct answer.
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Part 2) The basis for a maximum of one charging pump allowed OPERABLE below 350 oF provide assurance that a mass addition pressure transient can be relieved by the operation of a single PORV, or equivalent.

Comments:
K/A Match Analysis: The K/A requires knowledge of the bases in Technical specifications for limiting conditions for operations, and the question (part 2) clearly tests for that knowledge.
Distractor Analysis:
A. Correct Answer.
B. 1) Part 1 is correct. 2) Part 2 is incorrect because the basis clearly states that the mass addition transient can be relieved by the operation of a single PORV or equivalent. Plausible if candidate confuses the fact that while two PORVs will provide sufficient protection from pressure transients below 350 oF, the basis for a single charging pump is one PORV providing adequate protection, not two.
C. 1) Part 1 is incorrect. Plausible because above 350 oF two charging pumps may be OPERABLE, but at or below 350 oF a maximum of one charging pump is allowed.
Because question asks for sustained operation momentary operation of two charging pumps is incorrect as a reason for 2 charging pumps. 2) Part 2 is incorrect because the basis clearly states that the mass addition transient can be relieved by the operation of a single PORV or equivalent. Plausible if candidate confuses the fact that while two PORVs will provide sufficient protection from pressure transients below 350 oF, the basis for a single charging pump is one PORV providing adequate protection, not two.
D. 1) Part 1 is incorrect. Plausible because above 350 oF two charging pumps may be OPERABLE, but at or below 350 oF a maximum of one charging pump is allowed.
Because question asks for sustained operation momentary operation of two charging pumps is incorrect as a reason for 2 charging pumps. 2) Part 2 is correct for one charging pump, but is not correct for two charging pumps.

Level: SRO Tier #: 2 Group #: 2 IR - RO: 4.2 IR-SRO: 4.2 Proposed Question: !80 Initial Conditions for Unit 1:
- Unit 1 at 100% power.
- Delta Flux is at -2.7% with a target of -1%.
- Spurious Instrument failure causes rods to insert.
Current Conditions:
- Reactor Power is 89% and stable.
- Delta Flux is at -15%.
- Tave is 571.5 oF, Tref is 571.0 oF.
- Annunciator 1E-E3, Delta Flux Deviation is lit.
- Annunciator 1G-G8, Rod Bank D Lo Limit Based on the current conditions, which ONE of the following states:
- 1) The next action required to be taken to comply with Technical Specifications.
- 2) The most restrictive Tech. Spec basis for this CONDITION.
(REFERENCE PROVIDED)
A. 1) Restore Delta flux to target band within 1-hour or reduce power to < 50% in 1-hour.
- 2) Minimize the effects of Xenon redistribution during load-follow maneuvers.
B. 1) Restore Delta flux to target band within 1-hour or reduce power to < 50% in 1-hour.
- 2) Provide a limit on rod worth in the event of a rod ejection accident.
C. 1) Reduce reactor power to < 50% within 30 minutes.
- 2) Minimize the effects of Xenon redistribution during load-follow maneuvers.
D. 1) Reduce reactor power to < 50% within 30 minutes.
- 2) Provide a limit on rod worth in the event of a rod ejection accident.
Proposed Answer: C Explanation: 1) A Delta flux of -15% not only deviates from target but also deviates from maximum allowable deviation of TS Figure 3.12-3. At power levels < 90% the indicated delta flux deviation may deviate from its target band for a maximum of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (cumulative) in any 24-hour period provided the flux difference is within the limits of TS Figure 3.12-3. One minute penalty is accumulated for each minute of operation outside the target band. Because TS Figure 3.12-3 is violated (-10.8 is max) Tech
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Specs require power reduction to < 50% in 30 minutes. 2) The Delta Flux LCO is not met with Delta flux at -12.0. The basis for the Delta Flux LCO is to minimize the effects of xenon redistribution on the axial power distribution during load-follow maneuvers.

Comments:
K/A Match Analysis:
This question matches the K/A because the SRO must use the Delta flux information provided by Nuclear instrumentation to determine that an adverse trend in Delta flux is occurring. The Delta flux figure provide (Axial Flux Difference Limits which is also TS Figure 3.12-3) is a control room reference from 1E-E3, Delta Flux Deviation that would be provided to the Control Room Operator. This is an SRO level question because it requires detailed knowledge of Tech Spec actions, and power levels for which penalty minutes will accrue.
Distractor Analysis:
A. 1) Part 1 is incorrect because Delta flux is outside TS Figure 3.12-3 band which requires power reduction to < 50% in 30 minutes. Also time to reduce power to < 50% is 30 minutes, and not 1-hour. Plausible if candidate confuses max time for penalty minutes (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />) with max allowable delta flux deviation.

D. 1) Review Technical Specifications and monitor activity using the redundant monitor.
- 2) Provide a sensitive indication of primary system leakage.
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Proposed Answer: B Explanation: The situation posed by the question is indicative of an electronic check source failure.
The actions taken are from ARP 1-RMA-A1 and indicate a failure of 1-RM-127. Rad monitor readings are normal for both Containment Hi Range Rad monitors therefore per ARP 1-RMA-A1 the actions are to review technical specifications and monitor activity using the redundant monitor. There is no need to evacuate containment as there are no indications of a breach of radioactivity. The Tech Spec basis is to provide information to the operators that will enable them to determine the likelihood of a gross breach of barriers to radioactive release. It is the containment particulate and gas detectors that provide a sensitive indication of primary system leakage.

K/A Match Analysis: Question requires an understanding of the setpoint for the Alert/Trbl alarm FOR 1-RM-127 which is a containment area radiation monitor, therefore the question matches the K/A.
Distractor Analysis:
A. Incorrect. Part 1 are actions to be taken if there is an indication of high radiation in containment.
Plausible because these are actions taken from the ARP, and if candidate doesnt understand causes for the Alert/Trbl alarm, then this choice is likely. Part 2 is correct.
B. Correct.
C. Incorrect. Part 1 are actions to be taken if there is an indication of high radiation in containment.
Plausible because these are actions taken from the ARP, and if candidate doesnt understand causes for the Alert/Trbl alarm, then this choice is likely. Part 2 is incorrect. The CHHRMS do not have the same degree of sensitivity to leakage as the Containment particulate/gaseous detectors therefore this is false. Plausible because the Containment High Range Rad monitors can also deflect on primary system leakage, but the leakage would have to be fairly large or have fission products to cause significant deflection.

- A General Emergency has been declared.
- An individual has been injured in the Auxiliary Building penetration area.
- Dose rates in the area are 140 Rem/hr.
- It will take a maximum of 10 minutes to remove the individual from the area.
Which ONE of the following correctly describes the EPIP 4.04 requirements for:
- 1) Solicitation of a volunteer to rescue the individual.
- 2) Use of an RWP.
A. 1) Anticipated dose rates do NOT require the SEM to solicit volunteers to remove the injured worker;
- 2) An RWP is NOT required provided the SEM authorizes the activity.
B. 1) Due to anticipated dose for rescue workers, the SEM can assign ONLY volunteers to remove the injured worker;
- 2) An RWP is NOT required provided the SEM authorizes the activity.
C. 1) Anticipated dose rates do NOT require the SEM to solicit volunteers to remove the injured worker;
- 2) The SEM may NOT waive the requirement for an RWP.
D. 1) Due to anticipated dose for rescue workers, the SEM can assign ONLY volunteers to remove the injured worker;
- 2) The SEM may NOT waive the requirement for an RWP.
Proposed Answer: A Explanation: The individual used for rescue will receive a minimum dose of approximately 23.3 Rem based on current dose rates (140 R/HR 10/60 = 23.34 Rem). Per EPIP 4.04 only volunteers can be used if individual will receive > 25 Rem, therefore the SEM does not have to solicit a volunteer. The RWP may be waived if authorized by the SEM.

Level: SRO Tier #: 2 Group #: 2 IR - RO: 3.2 IR-SRO: 4.2 Proposed Question: !76 Given the following:
- Unit 1 is cooling down for refueling outage.
- RCS Tave is 349 oF.
- RCS Pressure is 360 psig.
Which ONE of the following correctly states:
- 1) The maximum number of charging pumps that are allowed per Tech Specs 3.1.G, RCS Overpressure Mitigation for sustained operation.
- 2) The basis for that requirement?
A. 1. one charging pump capable of injecting into the RCS.
- 2. To ensure that the mass addition transient, can be relieved by the operation of a single PORV or equivalent.
B. 1. one charging pump capable of injecting into the RCS.
- 2. To ensure that the mass addition transient, can be relieved by the operation of both PORVs, or equivalent.
C. 1. two charging pumps capable of injecting into the RCS.
- 2. To ensure that the mass addition transient, can be relieved by the operation of both PORVs, or equivalent.
D. 1. two charging pumps capable of injecting into the RCS.
- 2. To ensure that the mass addition transient can be relieved by the operation of a single PORV, or equivalent.
Proposed Answer: A Explanation: Part 1) Technical Specifications 3.1.G.c.(1) states: Whenever the RCS average temperature is less than or equal to 350 oF and the reactor vessel head is bolted: A maximum of one charging pump shall be OPERABLE and capable of injecting into the RCS. Two charging pumps may be in operation momentarily during transfer of operation from one charging pump to another. The question asks for the requirement for sustained operation therefore a maximum of one charging pump is the only correct answer.

K/A Match Analysis: The K/A requires knowledge of the bases in Technical specifications for limiting conditions for operations, and the question (part 2) clearly tests for that knowledge.
Distractor Analysis:
A. Correct Answer.
B. 1) Part 1 is correct. 2) Part 2 is incorrect because the basis clearly states that the mass addition transient can be relieved by the operation of a single PORV or equivalent. Plausible if candidate confuses the fact that while two PORVs will provide sufficient protection from pressure transients below 350 oF, the basis for a single charging pump is one PORV providing adequate protection, not two.
C. 1) Part 1 is incorrect. Plausible because above 350 oF two charging pumps may be OPERABLE, but at or below 350 oF a maximum of one charging pump is allowed.
Because question asks for sustained operation momentary operation of two charging pumps is incorrect as a reason for 2 charging pumps. 2) Part 2 is incorrect because the basis clearly states that the mass addition transient can be relieved by the operation of a single PORV or equivalent. Plausible if candidate confuses the fact that while two PORVs will provide sufficient protection from pressure transients below 350 oF, the basis for a single charging pump is one PORV providing adequate protection, not two.
D. 1) Part 1 is incorrect. Plausible because above 350 oF two charging pumps may be OPERABLE, but at or below 350 oF a maximum of one charging pump is allowed.
Because question asks for sustained operation momentary operation of two charging pumps is incorrect as a reason for 2 charging pumps. 2) Part 2 is correct for one charging pump, but is not correct for two charging pumps.

Comments:
K/A Match Analysis:
This question matches the K/A because the SRO must use the Delta flux information provided by Nuclear instrumentation to determine that an adverse trend in Delta flux is occurring. The Delta flux figure provide (Axial Flux Difference Limits which is also TS Figure 3.12-3) is a control room reference from 1E-E3, Delta Flux Deviation that would be provided to the Control Room Operator. This is an SRO level question because it requires detailed knowledge of Tech Spec actions, and power levels for which penalty minutes will accrue.
Distractor Analysis:
A. 1) Part 1 is incorrect because Delta flux is outside TS Figure 3.12-3 band which requires power reduction to < 50% in 30 minutes. Also time to reduce power to < 50% is 30 minutes, and not 1-hour. Plausible if candidate confuses max time for penalty minutes (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />) with max allowable delta flux deviation.

D. 1) Review Technical Specifications and monitor activity using the redundant monitor.
- 2) Provide a sensitive indication of primary system leakage.
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Proposed Answer: B Explanation: The situation posed by the question is indicative of an electronic check source failure.
The actions taken are from ARP 1-RMA-A1 and indicate a failure of 1-RM-127. Rad monitor readings are normal for both Containment Hi Range Rad monitors therefore per ARP 1-RMA-A1 the actions are to review technical specifications and monitor activity using the redundant monitor. There is no need to evacuate containment as there are no indications of a breach of radioactivity. The Tech Spec basis is to provide information to the operators that will enable them to determine the likelihood of a gross breach of barriers to radioactive release. It is the containment particulate and gas detectors that provide a sensitive indication of primary system leakage.

K/A Match Analysis: Question requires an understanding of the setpoint for the Alert/Trbl alarm FOR 1-RM-127 which is a containment area radiation monitor, therefore the question matches the K/A.
Distractor Analysis:
A. Incorrect. Part 1 are actions to be taken if there is an indication of high radiation in containment.
Plausible because these are actions taken from the ARP, and if candidate doesnt understand causes for the Alert/Trbl alarm, then this choice is likely. Part 2 is correct.
B. Correct.
C. Incorrect. Part 1 are actions to be taken if there is an indication of high radiation in containment.
Plausible because these are actions taken from the ARP, and if candidate doesnt understand causes for the Alert/Trbl alarm, then this choice is likely. Part 2 is incorrect. The CHHRMS do not have the same degree of sensitivity to leakage as the Containment particulate/gaseous detectors therefore this is false. Plausible because the Containment High Range Rad monitors can also deflect on primary system leakage, but the leakage would have to be fairly large or have fission products to cause significant deflection.
D. Incorrect. Part 1 is correct. Part 2 is incorrect. The CHHRMS do not have the same degree of sensitivity to leakage as the Containment particulate/gaseous detectors therefore this is false.
