Inc. Harris Nuclear Plant POBox 165 New Hill. NC 27562 Harris Nuclear Plant 2009a NRC Written Exam Question Contention On March 23, 2009 the HNP Written Exam was reviewed with all participating candidates.

During the review the SRO candidates identified two questions

(#83 and #87) that were inconsistent with the answer key. Based on the review of Harris Plant approved procedures the Harris Training Department supports post exam changes. Contention:

HNP SRO Written Exam (March, 2009) Question #83 has two possible correct answers Given the following plant conditions:

-The plant is operating at 100% power -The crew has noted indications that an RCS leak is in progress and has entered AOP-016, Excessive Primary Plant Leakage The following alarms and indications are observed:

-Plant Vent Stack #1 WRGM Effluent is alarming at 4.8E4 uCiisec and rising -Charging Pump IB Room Area Radiation monitor alarming at 1200 times normal and rising -GFFD is in alarm and has increased by 80,000 CPM over the last 20 minutes -lRM-ICR-3589-SA, CNMT HI Range Accident Monitor, is alarming at 14.7 Rlhr and rising -lRM-ICR-3590-SB, CNMT HI Range Accident Monitor, is alarming at 18.4 Rlhr and rising Which ONE of the following is the EAL classification to be declared for this event? (Reference provided)

A. EAL 2-1-1 B. EAL2-1-2 C. EAL 2-1-3 D. EAL 2-1-4 Plausibility and Answer Analysis A. Incorrect.

Plausible since the conditions for this classification have been met by the increase in GFFD, but this is not the most limiting EAL. B. Incorrect.

Plausible since the conditions for this classification have been met due to the Table 2 area rad monitor reading> 1200 times normal, but this is not the most limiting EAL. C. Correct. Multiple radiation alarms require evaluating Cnmt Hi Range Accident Monitors.

With one above the set point the correct classification is to identify two fission product barriers breached D. Incorrect.

Plausible since it is possible to reach a General Emergency based solely on Plant Vent Stack WRGM, but the thresholdfor this classification has not yet been reached KIA statement

-ARM System Alarms -Knowledge of the emergency action level thresholds and classifications.

Side 1 and Side 2 ofEAL Flow Path Rev. 06-1 References to be provided:

Side 1 and Side 2 ofEAL Flow Path Rev. 06-1 1 Harris Nuclear Plant 2009a NRC Written Exam Question Contention Question #83 Basis/or Contention:

Both Answers 'C' and 'D' are correct because insufficient information is provided in the stem of the question to adequately differentiate between the two answers. The first decision block of importance on the PEP-II 0 Emergency Action Level Flow Path Side 1 (Revision 06-1) is "EITHER CNMT HI RANGE ACCIDENT MON > 17.5 R/HR". Using information from the stem (IRM-ICR-3590-SB, CNMT HI Range Accident Monitor, is alarming at 18.4 RIhr and rising) this is given a YES response.

This YES response leads to "INDICATE FUEL AND RCS BREACHED ON FPB STATUS BOARD". With the determination that both the Fuel and RCS FPB are breached, at a minimum a Site Area Emergency exists (EAL 2-1-3) and therefore, answers 'A' and 'B' are incorrect.

The second decision block of importance on the PEP-II 0 Emergency Action Level Flow Path Side 1 (Revision 06-1) is "BOTH FUEL AND RCS INTACT ON FPB STATUS BOARD". This decision block is given a NO response as result of the previous discussion.

This NO response then requires evaluation of the "PATHWAY FOR FISSION PRODUCTS TO ESCAPE CNMT EXISTS OTHER THAN SECONDARY SYSTEMS (STEAMlFEED)" decision block. Given the detail provided in the stem, a YES or NO determination for this decision block becomes subject to interpretation.

The conditions given in the stem are a snapshot in time with no allowance for how long the trend existed or what the trend will be a time progresses.

It is this short fall that results in both Answers 'C' and 'D' being correct. Justification for a NO Response (Answer C, 2FPBs BREACHED/JEOPARDIZED):

With Containment radiation at the levels indicated in the stem, it is inferred that a Containment Ventilation Isolation Signal has occurred.

Because no indication of component failure is provided in the stem, it can be presumed that the valves are properly positioned and that a pathway does NOT exist for Fission Products to escape Containment.

This would result in indicating Containment INTACT on the FPB Status Board and arriving at EAL 2-1-3, 2FPBs BREACHED/JEOPARDIZED (Keyed Answer 'C'). Justification for a YES Response (Answer D, 3FPBs BREACHED/JEOPARDIZED):

With Containment radiation at the levels indicated in the stem it is inferred that a Containment Ventilation Isolation Signal has occurred.

Given that the Plant Vent Stack # 1 WRGM Effluent is alarming at 4.8E4 uCiisec and is rising a reasonable interpretation can be made that a pathway does exist for Fission Products to escape Containment.

This pathway could be through a mispositioned component or an RCS leak outside of Containment.

Containment Normal Purge discharges to the Plant Vent Stack and with these levels still increasing, some sort of discharge is being direct to the Plant Vent Stack. The information provided in the question stem only gave one fuel breach area radiation monitor vice multiple monitors that would have been in alarm. This led at least one candidate to assume the other radiation monitors were normal and therefore a leak was likely in the Charging pump room. This would result in indicating Containment Breached on the FPB Status Board and arriving at EAL 2-1-4, 3FPBs BREACHED/JEOPARDIZED (Answer 'D'). The recommendation from Harris Nuclear Plant is to accept two answers ('C' and 'D') for this question based upon NUREG 1021 ES-403 D.1.b page 3 guidance.

This question was written with an unclear stem that did not provide all the necessary information to distinguish between answers 'c' and 'D'. 2 Harris Nuclear Plant 2009a NRC Written Exam Question Contention Contention:

HNP SRO Written Exam (March, 2009) Question #87 has NO correct answer Given the following plant conditions:

-The plant is operating at lOO% power -Reactor Engineering is performing a flux map -OWP-RP-02 is in place for PT-456, Pressurizer Pressure Channel II, due to a failed bistable Repair of PT -456 will not be completed for another 17 hours1.967593e-4 days <br />0.00472 hours <br />2.810847e-5 weeks <br />6.4685e-6 months <br /> I&C reports the following:

-Due to errors in the MST during the last performance, the bistables for N-43 are set higher than the allowable values of Technical Specifications

-N-43 repairs will take 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> Which ONE of the following describes the action that must be completed for these conditions in accordance with OWP-RP and Technical Specifications?

A. Bypass N-43 until repairs are completed on PT-456 B. Stabilize power at less than 75% within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> C. Trip the bistables for N-43 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> D. Place the plant in Mode 3 within 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> Plausibility and Answer Analysis A. Incorrect.

This is plausible because Action 2.b. says the inoperable channel may be bypassed but this is only for surveillance testing and is only allowedfor up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. B. Incorrect.

This is plausible because Action 2.c requires power to be reduced to 75% within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or perform QPTR (flux map) every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Flux map is in progress and can continue.

C. Incorrect.

This is plausible because Action 2.a requires tripping bistables but precautions of OWP require checking bistables when taking instruments out of service to preclude a plant trip. D. Correct. Because taking the instrument out of service will produce a plant trip, Action 2.a cannot be performed 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> of Action 2. a and 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> of r.s. 3. 0.3 is a total of 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />.

None 3 Harris Nuclear Plant 2009a NRC Written Exam Question Contention Question 87 Basis/or Contention:

The question stem states that "the bistables" for NI-43 are set too high. This would require the improperly set bistables to be declared inoperable.

All Power Range NIS bistables are listed in Tech Spec Table 3.3-1 (page 3/4 3-2) Reactor Trip System Instrumentation, under functional units 2, 3, and 4. All of these bistables are covered by Action statement

1. 2 (applicable in Modes 1 and 2). ACTION 2 -With the number of OPERABLE channels one less than the Total Number of Channels, STARTUP and/or POWER OPERATION may proceed provided the following conditions are satisfied:

a. The inoperable channel is placed in the tripped condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> In order to comply with this Tech Spec either the inoperable bistables must be tripped within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> or the plant must be placed in a Mode that the spec is not applicable within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (Mode 3). Since action must be taken within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, answer D is incorrect because it would allow the plant to remain in Mode 1 for up to 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />. Answer C is still incorrect.

Although it complies with the correct Tech Spec time for bistables to be tripped since the stem referred to "the bistables" and did not specify any specific bistable, it also requires the channel III OTLlT bistables to be tripped. This would result in a plant trip since the channel II OTLlT bistables were previously tripped. Precautions in the OWP require ensuring previously tripped bistables will not make up a Reactor trip coincidence prior to tripping the bistables for the current inoperable instrument channel. If the actions on Answer D were taken then Tech Specs would be violated.

If Answer C actions were taken then the OWP-RP would be violated and a resultant plant trip. Therefore, neither action could be done to comply with both Tech Specs and OWP-RP. The recommendation from Harris Nuclear Plant is to remove the question from the exam due to no correct answer based upon NUREG 1021 ES-403 D.1.b page 3 guidance.
