Given the following: - The plant is at 100% power. - AFW Pump B is running for a surveillance test in progress. - Annunciator 47061-M, AFW PUMP B LOW OIL PRESS, alarms. What is the expected operator response for this condition? A. Trip AFW Pump B, and go to N-FW-O5B, Auxiliary Feedwater System.

B. Trip AFW Pump B and go to A-FW-056, Abnormal Auxiliary Feedwater System Operation. Feedwater System.

C. Verify the Auxiliary Lube Oil Pump is running, and go to N-FW-O5B, Auxiliary D. Verify the Auxiliary Lube Oil Pump is running, and go to A-FW-O5B, Abnormal Answer: D Recommendations: Auxiliary Feedwater System Operation.

Accept both "B" and "D as correct operator actions.

The premise states, "Annunciator 47061-M, AFW PUMP B LOW OIL PRESS, alarms," but does not provide additional cuing as to the continuing alarm status. However, without providing indication of what the current oil pressure value and trend is, the operator cannot make a valid decision as to the appropriate action between the two selections mentioned above.

AFW Pump B Aux Lube Oil Pump starts at the same setpoint as when this alarm actuates

(< 10 psig). But if lube oil pressure is continuing to drop, the AFW pump will trip at I4 psig lube oil pressure.

It would be prudent to stop the AW Pump prior to the lube oil pressure reaching this point if the pressure were continuing to decrease. Without the oil pressure value or trend information, the operator relies on conservative decision making skills and operating judgment as to which action is appropriate.

UG-0, User's Guide For Emergency And Abnormal Procedures, section 6.1.2, provides during abnormal conditions, an operator has the authority to take action that is clearly needed based on observed condition.

It is recommended that two answers be accepted, "6 and "D, for the given conditions.

The bank question will be changed appropriately to solicit only one correct answer.

Serial No. 05-81 5 Operator License Examination Enclosure 1 - page 2 of 2 67. Given the following: - Waste Gas Decay Tank A is in service. - The relief valve for that tank, WG-l4A, lifts and fails to reseat. What is the effect on the plant? A. The release will be automatically isolated when the Waste Gas Analyzer senses the pressure drop in the Waste Gas Decay Tank. B. The release will be automatically isolated when the Waste Gas Decay Tank pressure reducing control valve WG-201 closes.

C. The release will NOT be automatically isolated, but will be monitored by the Aux. Building Vent radiation monitors R-13 and R-14. D. The release will

_NOT be automatically isolated, but will be detected by the Charging Pump Room Area Monitor R-4.

Answer: C Recommendations:

A pen and ink correction is required to properly identify the Waste Gas Decay Tank A relief valve. The actual valve nomenclature is WG-13A. The premise identifies the Waste Gas Decay Tank A Relief Valve as WG-14A. The actual valve identifier is WG-13A.

It is believed that this error does not invalidate the question but should be treated as a typographical error. WG-14A is not the relief valve but has the nomenclature, "WG-14NCV-31209 Waste Gas Tank 1A to Holdup Tanks." During the examination no individual questioned the difference between the valve number and the description provided.

If someone thought the valve in question was other than the Waste Gas Decay Tank Relief, this should have been questioned during this time. Since the valve WG-14A is not a relief valve it does not "lift" but may fail open. This valve does align the Waste Gas Decay Tank to vent header and provides cover gas for the HUT. It is normally open when the waste gas decay tank is providing the cover gas. The only limitations on operation per N-GWP-32B are

1) Normally the gas decay tank with the highest pressure (greater than 8 psig and NOT on holdup for decay) should be selected for cover gas; and 2) when the Boric Acid Evaporator is running, the gas decay tank on fill shall not be selected to provide cover gas to the vent header. Also any gas decay tank less than 110 psig may be selected for fill. WG-15 is a regulating valve that maintains the CVCS HUT cover gas pressure. None of the above conditions are affected by the question. Therefore, it is incorrect to assume that the vent header ruptures, releasing the gas.

COLLECTED STUDENT EXAM ITEM FEEDBACK

SUMMARY

AND RESPONSE

32. Given the following: -The plant startup is in progress. - Reactor power is 1.4%. - FW-07A & B, S/G Main Feed valves, AND FW-IOA

& B, S/G Bypass Feed valves, indicate closed. - Feedwater Pump A has just been started. - SG B level begins to slowly rise.

What action is required?

A. Direct the NAO to locally close FW-9B. Feedwater Main Control Valve I9 Bypass Valve Inlet. B. Cycle FW-IOB, S/G B Bypass, fully open and closed.

C. Close FW-12B. S/G B Feedwater Isolation Valve. D. Stop Feedwater Pump A Answer: C Student Comment: Accept 2 answers: (C) Also if level was near the high level trip @ 67%) stopping the FW Pump is a viable answer to preclude damage to secondary system and turbine. Resolution and Comments There is only one correct answer for the given conditions Based on the given conditions, guiding procedures are N-0-02, Plant Startup From Hot Shutdown to 35% power, and N-FW-OSA, Feedwater System Normal Operation.

Per N-0-02, the initial conditions are SG NR level is maintained between 33% and 50%. The question gives no reason for NOT having this level band established.

Furthermore, conditions in the premise state that SG B level begins to slowly rise. Thus there is no basis for assuming SG level is near or approaching the SG Feedwater Isolation setpoint of 67%. The correct answer for closing the affected SG Isolation MOV is the result of operational experience and is procedurally directed in N-FN-OSA.

The NOTE and actions or stcp 4. I .4.j (CAS) are taken immediately after starting a FW Pump. (See attachcd page.)

No action required.

34. Given the following: -The plant is at 100% power. - AFW Pump B is running for a surveillance test in progress Annunciator 47061-M, AFW PUMP B LOW OIL PRESS, alarms What is the expected operator response for this condition?

A. Trip AFW Pump E, and go to N-FW-OSB, Auxiliary Feedwater System. B. Trip AFW Pump B and go to A-FW-OSB, Abnormal Auxiliary Feedwater System Operation.

C. Verify the Auxiliary Lube Oil Pump is running, and go to N-FW-OSB, Auxiliary Feedwater System. D. Verify the Auxiliary Lube Oil Pump is running, and go to A-FW-OSB.

Abnormal Auxiliary Feedwater System Operation.

Answer: D Student Comment: Per the stem of the question, we are in a surveillance test with Annunciator 47061-M, AFW PUMP B LOW OIL PRESS, ON. With that alarm on steady it raises a question with the Aux Lube Oil System that it is not operating properly. (It auto starts at IO# and cycles off at IS.S#.) With both the shaft-driven lube oil pump and the aux lube oil [pumps] because the alarm is not clearing.

The AFW Pump is being run to support the surveillance procedure, not to rcmove decay heat. Per UG-0 (Rev. F), User's Guide For Emergency And Abnormal Procedures, section 6.1.2, during abnormal conditions, an operator has the authority to take action that is clearly needed based on observed condition.

With the annunciator 47061-M not clearing, there is a lube oil problem. Conservative Decision Making, would require we stop the [AFW] pump.

My recommendation is to accept answer "B" as well as "D", per the Key Resolution and Comments The student is incorrect in assuming the alarm is in steady. The premise states, "Annunciator 47061-M, AFW PUMP B LOW OIL PRESS, alarms," but does not provide additional cuing as to the continuing alarm status.

However, without providing indication of what the current oil pressure value and trend is, the operator cannot make a valid decision as to the appropriate action between the two selections mentioned above. B AFW Pump aux lube oil pump starts at the same setpoint as when this alarm actuates

(< 10 psig). But if lube oil pressure is continuing to drop, the AFW pump will trip at E 4 psig lube oil pressure.

It would be prudent to stop the AFW Pump prior to the lube oil pressure reaching this point, if the pressure were continuing to decrease It is recommended that two answers be accepted - "B" and "D'. The Evaluation Instruments required change and the question requires change to identify the lube oil pressure value and trend, if "D' is to be the only correct answer.

44. Which of the following situations requires entry into a Technical Specification LCO Action? A. Pressurizer Pressure Transmitter P-429 fails low while at 3810 power, B. Pressurizer level decreases to less than 17% with a reactor startup in progress.

C. Pressurizer Backup Heaters energize after a 8% load reduction D. Pressurizer Pressure Transmitter P-449 fails high while on RHR Cooling Answer: A Student Comment: Accept 2 answers. Answer "D' is also correct.

The ACTION if conditions cannot be met is to MAINTAIN HOT SHUTDOWN.

The ACTION must still be entered even if it is already satisfied.

Action must be maintained to maintain these conditions.

Resolution and Comments By the definition from Technical Specifications, LIMITING CONDITIONS FOR OPERATION are those restrictions on reactor operation, resulting from equipment performance capability that must he enforced to ensure safe operation of the facility.

PT-449 does serve a safety function in that it provide a reactor trip on low PRZR pi-essure and one OTDT channel when the plant is operating above the P-7 setpoint (3/4 Power Range Nuclear Instruments channels c 10% AND 2 of 2 Turbine Impulse Pressure Channels < 10% power). The Functional Unit No. 7 (TABLETS 3.5-2) has a PREMISSIBLE BYPASS CONDITIONS of P-7. Functional Unit No. 5 (OTDT) does not have PREMISSIBLE BYPASS CONDITIONS.

BOTH have an action that if MINIMUM OPERABLE CHANNELS (3) or MINIMUM DEGREE OF REDUNDANCY (I) are not met then the operator must maintain HOT SHUTDOWN.

With the plant on RHR Cooling, the reactor must be shutdown and RCS WR Hot Leg temperature is < 400°F and RCS pressure is f 425 psig. The plant is in INTERMEDIATE SHUTDOWN, and therefore, the LCO for PT-449 does not apply.

Rather than listing the LCO restraint, the out of service item is controlled through its associated Work Order, and this is controlled to ensure completion and retuin to service before the Technical Specification required time by tying to the Mode Change Checklist. This ensures that LCO conditions are identified and entry prevented by changing plant conditions.

"A" is the only correct answer, for. which entry into the LCO conditions for TABLETS 3.52 Functional Unit No. 5 (OTDT trip), TABLETS 3.5-2 Functional Unit No. 7, TABLETS 3.5-2 Functional Unit No. 8 (High Przr Pressure trip), and TABLE TS 3.5.3 Functional Unit No. I .d (Pressurizer low pressure Safety Injection).

The associated bistables for thc failed channcl must be tripped within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> per A-MI-87. No action required.

62. Given the following:

Plant is at 90%) power - Power Range Instrument N-42 fails and is removed from service per A-MI-87, Bistable Tripping for Failed Reactor Protection or Safeguards Inst. - The surveillance for SP-47-01 IA, Reactor Coolant Temperature and Pressurizer Pressure Instrument Channel I (Red) Calibration, comes due. - The decision is to bypass the failed NIS channel inputs to allow the calibration (Technical Specification 3.5.d). What is the coincidence for the OTDT reactor trip while the surveillance is in progress?

A. 2outof2 B. 2outof3 C. 1 out of4 D. I out of 3 Answer: B Student Comment:

In a normal lineup, the OTDT trip coincidence is 2/4 (4 channels provide input, 2 req'd to actuate).

With N-42 input to Chan I1 OTDT trip bypassed, only 3 channels provide input; 2 are still req'd to actuate, therefore coincidence

= 2/3. During SP-47-01 IA, aftcr initial switch lineups and verifications, the bistables associated with the RED Channel Pressure

/ Temperature trips are placed in TEST. After that step (3 channels still provide input; 1 more -BLUE or YELLOW - is req'd to actuate the trip), therefore the coincidence becomes 1/3. The correct answer depends on which actions of SP-47-01 IA have been completed. This information is not provided, only that ". , . the surveillance is in progrcss."

As written, "B" and "D' are correct. I recornmcnd accepting both. Resolution and Comments The coincidence does depend on the step one is performing in the procedure.

At Step 6.3.17 the associate bistables are placed in TEST (tripped).

The bistables are restored to NORMAL at step 6.10.15 near the end of the surveillance.

During the period between these steps the coincidence is 112 for tripping the reactor. Since the one channel is already tripped, it takes the input from one of the remaining two channels to trip the reactor. The overall coincidence for the trip is still 23 (with the fourth channel bypassed), but the situation is the one channel of trip input is alrcady made up. "1 out of 2" is not a listed selection An individual later requested clarification of the status of performing the surveillance.

It was answered that the surveillance had not yet been entered. This information was provided to all students in the room at that time. The individual providing this feedback was not in the room, as he had completed his examination earlier.

No change required

63. Given the following: -Power level IS 99.9% (1771.5 MWt) - The current UFMD and RTO OPERATING LIMITS are 1772 MWt - SP-87-125, Shift Instrument Channel Checks - Operating, calorimetric was completed 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> ago. - The signal is lost to PPCS from Feedwater Flow channel FT-476 -The RTO I-minute average, PPCS point RSIIOG, drops to 1200 MWt - The Computer Group reports the signal will be restored within 10 minutes What is the affect on the UFMD and RTO Operating Limits, and what action is taken when the flow channel input is restored and RS110G reads normal? A. Both the UFMD and RTO Operating limits will read 1749 MWt. When the signal is restored, the operator will click the APPLY UFMD LIMIT hutton on the PPCS UFMD Correction Factors screen to return both limits to 1772 MWt. B. The UFMD Operating Limit will read 1749 MWt and RTO Opciating Limit will read 1772 MWt. Power will be reduced to less than 1749 MWt, and when the signal is restored, the operator will click the APPLY UFMD LIMIT button on the PPCS UFMD Corrcction Factors screen to return the UFMD limit to 1772 MWt. C. Both the UFMD and RTO Operating limits will read 1769 MWt When the signal is restored, the operator will click the APPLY UFMD LIMIT button on the PPCS UFMD Correction Factors screen to return both limits to 1772 MWt. D. The UFMD Operating Limit will read 1769 MWt and RTO Operating Limit will read 1772 MWt. Power will be reduced to less than 1769 MWt, and when the signal is restored, the operator will click the APPLY UFMD LIMIT button on the PPCS UFMD Correction Factors screen to return the UFMD limit to 1772 MWt.

Answer: A Student Comment:

No Correct Answer. When the flow channel is returned, the UFMD will go to 1772 with only 10 minutes of data lost. When clicking the "APPLY UFMD LIMIT" button, this &changes the RTO Limit, not "both" the RTO and the UFMD Limit.

This is supported by N-0-03 step 4.1.14.c. The action of clicking the button does not affect both limits. Resolution and Comments The information about reset of the RTO and UFMD Limits is true. When the feed flow is restored above 70% reactor power equivalent the UFMD Operating Limit will automatically reset to 1772. To restore the RTO Operating Limit the operator must depress the APPLY UFMD LIMIT button.

Then the RTO Limit will be reset to 1772. Selection "A' describes this condition.

To have both the UFMD Operating Limit AND the RTO Operating Limit read 1772, the operator must click the APPLY UFMD LIMIT button. There was no clarification requested for this question during the examination No change required

67. Given the following: - Waste Gas Decay Tank A is in service - The relief valve for that tank, WG-I4A, lifts and fails to reseat What is the effect on the plant?

A. The release will be automatically isolated when the Waste Gas Analyzer senses the pressure drop in the Waste Gas Decay Tank.

B. The release will be automatically isolated when the Waste Gas Decay Tank pressure reducing control valve WG-201 closes. C. The release will NOT be automatically isolated, but will be monitored by the Aux. Building Vent radiation monitors R-13 and R-14. D. The release will NOT be automatically isolated, but will be detected by the Charging Pump Room Area Monitor R-4.

Answer: C Student Comment: In the stem of the question it lists WG-14A as the relief valve for WGDT A. It is not. The stem of the question is wrong. If WG-14A were to lift at full tank pressure it could rupture the vent header and R-4 could be a possible answer. Recommendations: Accept both answers "C" and "D' and revise question.

Resolution and Comments While the question does use the incorrect valve identifier number, WG-14 A versus WG-I3A, it does identify the valve as the "relief valve for that tank." WG-I4A is not the relief valve but has the nomenclature, "WG-14A/CV-31209 Waste Gas tank 1A to Holdup Tanks." During thc examination no individual questioned the difference between the valve number and the description provided.

If someone thought the valve in question was other than the Waste Gas Decay Tank Relief, this should have been questioned during this timc. The valve number eror is a typographical error and does not affect the quality of the question.

Since the valve WG-14A is not a relief valve it does not "lift" but may fail open. This valve does align thc Waste Gas Decay Tank to vent header and provides cover gas for the HUT. It is normally open when the waste gas decay tank is providing the cover gas.

The only limitations on operation per N-GWP-32B are

1) Normally the gas decay tank with the highest pressure (greater than 8 psig and NOT on holdup for decay) should be selected for cover gas; and 2) when the Boric Acid Evapomtor is running.

the gas decay tank on 'fill shall not be selected to provide cover gas to the vent header. Also any gas decay tank less than 110 psig may be selccted for fill. WG- 15 is a regulating valve that maintains the CVCS HUT cover gas pressure.

No of the conditions above are affected by the question so it unsupported in assuming the vent header ruptures releasing the gas. While the charging Pump room, the location of R-4 monitor, is on the same elevation and in the near vicinity of the Waste Gas Decay Tank cubicles, each is provided with separate ducting to the plant exhaust vent. With flow rates in the ventilation system of 300 CFM for the WGDT vault and 850 CFM for the Charging Pump room.

It is unlikely a leak would bee detected by R-4. However this same leak would be detected by R-13 and R-14. The Evaluation does not require change. A Question Change is required to correct the valve identifier number.

SI. Given the following: -The plant is at 100% power. - Surveillance Test SP-42-312B, Diesel Generator B Availability Test, is in progress with DG B running. - Component Cooling Pump B trips on overcurrent. - BRB-104, ckt 10 supplying DG B tripped open and CANNOT he closed. What is the effect of this condition?

A. DG B is inoperable and must have its fuel supply locally isolated A plant shutdown must commence within one hour using the Standard Shutdown Sequence (Technical Specification 3.0.c). B. DG B is Degraded but Operable and can be controlled locally. A 24-hour LCO is applicable for restoration of the DC Distribution System and a 72-hour LCO is applicable for restoration of Component Cooling Pump B. C. DG B is inoperable and must have its fuel supply locally isolated.

A 72-hour LCO is applicable for restoration of Component Cooling Pump B and a 7-day LCO is applicable for restoration of DG B. D. DG B is Degraded but Operable and can be controlled locally.

Only the 72-hour LCO is applicable for restoration of Component Cooling Pump B Answer: C Student Comment: This question has two answers dependent on the time frame. Answer "C' is correct initially at the failure. The 2"d answer is "A," "A" is correct as well due to the following.

With B DG OOS, A DG must be tested every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to verify operability.

In order to test A DG, all B train ESF equipment is required to be OPERABLE 9as indicated in SP-42-3 12A). Since B CC Pump is OOS, this condition is not satisfied and therefore 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to commence a shutdown applies.

Resolution and Comments The conditions given do not warrant this extrapolation of conditions. Applied to the current conditions, the Technical Specifications that apply are for DG B and CC Pump 6. TS 1.3.d.2 list a 72-hour LCO for the CC Pump and TS 3.7.b.2 & 3.7.c identify a 7-day LCO for restorins the DG. This is the condition that applies at the time given. (It does not indicate when the CC Pump or the DG is actually returned to service.)

If the time period came when DG A was required to be run per SP-42-3 12A, then the TS requirement for Train B equipment would need to be addressed.

If this were the condition, then this information would have been included in the question premise.

No action required.

88. What is the reason for the Feedwater Isolation signal generated from High-High SG level? A. Preclude excessive SG tilts due to cooler feedwater supplied to ONE SG. B. Prevent overfill of the SG that may result in damage to secondary components C. Ensure containment pressure remains within maximum internal pressure limit with the affected SG faulted inside containment.

D. Protect the Feedwater Pumps from operating in runout condition with FW-7A/B, S/G A/B Main Valve, fully open. Answer: B Student Comment:

Accept 2 answers: "C" & "B" Per USAR Section 14, pages 14.2. 21-25, one of the 4 major factors that influence release of mass and energy is SIG water level (fluid inventory).

The analysis was based on 445% NRL

• uncertainties. Having too much inventory is a reason to challenge containment integrity.

Resolution and Comments The concern above is true, and that is why SG level is maintained in the normal band during operations.

However this does not address the specific reason for having the Feedwater Isolation signal on SG high level. The isolation occurs to prevent SG overfill.

SG Overfill may result in damage to secondary components, including erosion of turbine blades due to high moisture steam. No action required

90. Given the following: - The plant has experienced a fire in the Control Room. - The actions of E-0.06, Fire In Alternate Fire Zone, are being performed What are the indications of an air dryer filter failure, and what are the procedural actions performed by the Control Room Supervisor to mitigate the consequences of this failure.

A. Instrument Air DrierRilter IA/IB differential pressure will rise above 5 psid The CRS will verify SA-121, Air DrierRilter Bypass CV, opens. B. Instrument Air DrierFilter IC differential pressure will rise above 10 psid. The CRS will open SA-IOOA, Air Drier 1A Supply, and IA-300, 1 1/2" Alt IA, and then request the Control Operator A to start Air Compressor B. C. Instrument air header pressure will drop below 95 psig The CRS will depress the Air Drier IC RESET pushbutton to confirm problem, and then align flow through Instrument Air Drier 1B. D. Instrument air header pressure will drop below 100 psig. The CRS will open SA-70 and SA-71, I 1/2" Dedicated Instrument Air Header Isolations, that bypass the Instrument Air Driers. Answer: D Student Comment: A failure of IA Dryer is more likely to result in a high DIP across IA-I21 well before IA pressure begins to degrade.

The opening of IA-121 is an Immediate Automatic action that should be verified by the local operator, in this case, the CRS Opening SA-70 and [SA-] 7 I is directed by E-0-06, but not in response to this Failure. 'This is the path that is provided to supply the Dedicated IA header from Air Compressor C. However, since this line does effectively bypass the Instrument Air Dryers, both answers "A" and "D" are correct responses.

I rccornmend accepting both for credit and revising the question. Resolution and Comments Indeed SA-I21 will open in response to a high differential pressure across the Air DryedFilter, and the actions under normal conditions would be to verify this valve is open (as directed by the annunciator alarm condition).

However in this situation the control room is evacuated and E-O- 06 is in progress.

As the question asks, what are the actions that mitigate this condition? The answer is the Air Dryers are bypassed by opening the Dedicated Air Header isolations, which supply the air directly through a separate in-pipe air dryer. "A" is not a correct answer because the CRS does not verify this path, and actually isolates this path when performing step

19. By closing SA-IOOB and SA-2C, the air supply from Compressor C (which is the one to be verified working) is isolated to the Instrument Air Dryers A and B, and thus SA-I21 opening has NO effect. No action required.

1. 2. 3. 4. 5. 6. 7. When the need for a turbine trip, reactor trip. or safety injection is imminent or unavoidable, the operator should initiate these signals manually whenever possible.

a. If a manual turbine trip. reactor trip or safety injection is deemed necessary, the crew member recommending or ordering the action should state the reason for the action. This will allow the remaining crew members to independently evaluate the current plant conditions and validate or refute, as necessary.

the need for the manual action. If plant conditions warrant, the SM or CRS may choose to allow automatic actuation of these protective features.

b. During abnormal and emergency conditions.

an operator has the authority to take action that is clearly needed based on observed plant conditions before being directed by procedures.

provided such action is not contrary to the procedure currently in effect and does not hamper the completion of the procedure steps.

Automatic controls not performing their intended function should be manually controlled.

Components which require manual control shall be reported to the procedure reader when the applicable step is read. All failures of plant components shall be reported to the CRS andlor SM. Annunciators shall be promptly noted, acknowledged.

and verified against plant conditions per FP-OP-COO-01.

CONDUCT OF OPERATIONS.

Concerns or objections to the stated or intended course of action along with the basis for these concerns or objections shall be made known as soon as possible.

a. If time permits. the stated concerns or objections shall be discussed with and resolved by the SM and/or CRS.

Maximum current is 1073 amps, expected when the RXCP is operating at cold loop condition and minimum bus voltage value of 3600 volts. C. Maximum current is 976 amps, expected when the RXCP is operating at hot loop condition and maximum supply voltage of 4400 volts.

D. Maximum current is 745 amps, expected when the RXCP is operating at hot loop condition and minimum supply voltage of 3600 volts. Answer: B N-RC-36A, Rev. AG, APPENDIX A identifies the maximum current as 1073 amps. This condition will occur when the RXCP has to move the more dense fluid (cold RCS loop temperature) and when the supply voltage is at its minimum value (3600 volts, E/I = R) R02-01-LP36A, Rev.

SUMMARY

50. Given the following: - The plant is at 100% power. - Diesel Generator (DG) A is supplying Bus 5 in parallel to the offsite power source. What occurs if the EMERGENCY VOLTAGE SHUTDOWN button for DG A is pressed? A. A Bus 5 Lockout is generated B. Diesel Generator A engine trips.

C. Diesel Generator A engine will begin to motor. D. Breaker 1-509, DG A to Bus 5, trips Answer: D E-2022, Rev. N for DG A shows depressing the Local Panel Pushhutton, VOLTAGE SHUTDOWN, with DG speed greater than 700 rpm and the Voltage Shutdown RESET pushbutton NOT depressed, will provide and output signal to a NOT box and provide a seal in until the RESET button is depressed, This condition removes the input to the NOT box that feeds TRIP BREAKER 1-509. The Alarm Response sheet for 47094-A, DIESEL GEN A EXCITATION VOLT DEENERGIZED, Comment 1, "Alarm is activated when DG A speed is > 700 rpm AND Emergency Voltage Shutdown pushbutton has been depressed." The Recommended Action for the Annunciator is, "1. VERIFY Bkr 1-509 DG A to Bus 5 OPEN." R02-03-LP42A, Rev. B, Diesel Generators, section A.6.d. l).f) describes the Voltage Shutdown pushhutton operation.

It states that the Voltage Shutdown provides for rapid DG voltage shutdown by, 1) puts a short circuit across the DG field windings;

2) prevents filed flash; and 3) trips DG output breaker.

The associated PPT slide #92 covers the DG Control and Excitation Cabinet Controls, including the function of the Emergency Voltage Shutdown pushbutton.

SUMMARY

67. Given the following: -Waste Gas Decay Tank A is in service. -The relief valve for that tank, WG-I4A, lifts and fails to reseat. What is the effect on the plant? A. The release will be automatically isolated when the Waste Gas Analyzer senses the pressure drop in the Waste Gas Decay Tank. B. The release will be automatically isolated when the Waste Gas Decay Tank pressure reducing control valve WG-201 closes.

C. The release will NOT be automatically isolated, but will be monitored by the Aux Building Vent radiation monitors R-13 and R-14. D. The release will NOT be automatically isolated, but will be detected by the Charging Pump Room Area Monitor R-4.

Answer: C Per drawings (OPERXK-100-132, Rev. AF) each WGDT relief goes to a common relief header that is routed into either the ducting for the SV Zone exhaust or the Aux. Bldg Ventilation exhaust headers (OPERM-604 and OPERM-601, respectively).

The ducting is a direct path to the Aux Bldg Vent that is sampled by R-13 and R-14.

R02-01-LP045, Rev. B, Radiation Monitoring, section G.2.c describes the function for R-13 and R-14 of continuously monitoring the Aux Bldg vent flow path. It also states the detectors are high sensitivity bets-gamma used to measure gaseous activity of air discharged out the stack. AOI-81-LP32B, Rev. A, Gaseous Waste Processing

& Discharge, section C.5.f describes the Waste Gas Decay Tank relief valves.

The valves are set at 150 psig and relieve to the AUX Bldg and Zone SV Exhaust.

SUMMARY

76. Given the following: -The plant was stable with reactor power at 100%. -A reactor trip and safety injection occurred due to a Pressurizer PORV failing - All safeguards equipment has responded per design. - The crew implemented E-0 and transitioned to E-I, Loss of Reactor or - The failed PORV has just been isolated. - The crew is currently performing Step 12 of E-I, "Check If SI Should Be open and remaining full open. Secondary Coolant.

Terminated".

Which Combination of SI Termination Criteria is expected to be satisfied at this point? A. Pressurizer level AND secondary heat sink 6. RCS subcooling AND secondary heat sink C. Pressurizer level AND RCS subcooling D. Pressurizer pressure AND RCS subcooling Answer: A lhis is a similar event to the Three Mile Island accident and gives conditions where RCS pressure would be low, RCS CET temperatures would remain relatively high and PRZR level would remain high due to the leak location and voiding in the vessel head. In this instance it should be recognized that PRZR level would be 1 5% as required for the SI Termination Criteria and that since the secondary is unaffected, SG levels ( > 4% [IS%] NR level) OR AFW flow requirements ( > 205 gpm available) would also be acceptable.

However, due to the low RCS pressure and likely RCS temperatures, RCS subcooling

(> 30°F [65'F]) and PUR pressure ( 2200 psig [2000 psig]) are unlikely to be met. Page 6 WRITTEN EXAMINATION ITEM REVIEW DETAILED

SUMMARY

98. Given the following: -A LOCA has occurred -A radioactive spill has occurred in the Auxiliary Building. -An SITE EMERGENCY has been declared. -All ERO positions have been filled. - Entry into the Auxiliary Building is required to repair the leaking flange on the - Estimated dose for the entry and work is 7 REM TEDE. RHR system What are the MINIMUM requirements that must met for this entry into the Auxiliary Building? A. EPIPF-AD-11-04, Emergency Exposure Authorization, and EPIPF-AD-1 1-01 , Emergency Radiation Work Permit, must be completed and approved prior to entry. B. EPIPF-AD-11-04, Emergency Exposure Authorization, must be completed and approved prior to entry, and the individuals must sign onto the existing Maintenance Radiation Work Permit prior to entry.

C. If a Priority Entry is made, EPIPF-AD-11-04, Emergency Exposure Authorization, must be completed and approved prior to entry, and EPIPF-AD-11-01, Emergency Radiation Work Permit, must be completed immediately following the completion of the entry.

D. If a Priority Entry is made, EPIPF-AD-11-04, Emergency Exposure Authorization, and the individuals must log entry on the existing Maintenance Radiation Work Permit immediately following the completion of the entry. Answer: A The requirements for a completing an ERWP and the Emergency Exposure Authorization Form prior to entry into an area where IOCFR20 dose limits are likely to be exceeded is covered in EPIP-AD-11.

The identification that such an entry is NOT a "Priority Entry" is also provided there and in EPIP-RET-02D.

EPI-01 -LPOOl, Rev. B, Emergency Preparedness Overview, section I.4.d.2 states that under certain circumstances lOCFR20 limits may be exceeded during major radiation emergency and the approval of the ED is required.

EPI-01-011, Rev. B, Emergency Actions For The SRO, section F.Z.a.Z).b) provides identification of the responsibility of authorizing exposures in excess of 1 OCFR20. Section Page 7 WRITTEN EXAMINATION ITEM REVIEW DETAILED

SUMMARY

H.5.a. l).b) identifies EPIP-AD-11 "Emergency Radiation Controls" as the means of controlling exposures for the emergency workers.

The associated PPT does not cover this but under PARS identifies the Kegulatory Requirements of 10CFR50.47 for controlling does to on-site workers.

lhis may be an area for improvement in preparation for NRC examination, as emergency exposures do not appear to be specifically covered. Page 8
