Conditions are as follows:
- 2SLS*P1A and P1 B Standby Liquid Poison (SLC) pumps are not available due to motor electric faults
- 2SLS*MOV1A, STORAGE TANK OUTLET VLV is stuck shut and cannot be opened.
Per N2-EOP-6, which one of the following lineups will allow boron to be injected into the RPV to shutdown the reactor?
Hydro Pump Born Injection via 2SLS*P1 B Piping l 3 Boron Injection Via WCS System Lineup number. ..
A. 3 only B. 1 or 3 only C. 2 or 3 only D. 1,2, or 3 Proposed Answer: C Explanation (Optional):
A. Incorrect. Although injection via WCS is a method for injecting boron into the core, the SLS failure given in the question stem does not preclude using SLS B piping to also inject the boron. Plausible in that if the candidate does not know the lineup used to
inject boron via the hydro pump, they may think that the failure given in the question stem precludes the use of using the B SLS pump piping to inject boron.
B. Incorrect. The SLS failure given in the question stem does precludes using SLS A piping to inject the boron. Plausible if the candidate does not know that there are two methods allowed per Attachment 16 to inject boron using the hydro pump and that the suction valve is required to be open in order to use it.
C. Correct. The SLS failure given in the question stem precludes the use of SLS A to inject boron using the hydro pump. Since SLS B is still available, boron injection can be lined up via this train. Additionally, boron injection via WCS is still available.
D. Incorrect. The storage tank outlet valve for SLS A needs to be open in order to use the SLS A train to inject born via the hydro pump. Plausible in that if the candidate does not know the hydro pump suction connection comes off downstream of the storage tank outlet valve this would be the correct answer.

- Drywell pressure trip unit C72-N650A fails upscale
- 603101, RPS A DRYWELL PRESSURE HIGH TRIP annunciator alarms Which one ofthe following lists (1) the GTS Train A response and (2) the GTS Train B response?
A. (1 ) GTS Train A will continue to run in containment vent mode via the drywell (2) GTS Train B will remain in standby B. (1 ) GTS Train A will continue to run in containment vent mode via the drywell (2) GTS Train B will automatically initiate C. (1 ) GTS Train A will continue to run, however CPS*AOV110, DRYWELL PURGE OUTLET OUTBOARD ISOL VLV closes (2) GTS Train B will remain in standby D. (1 ) GTS Train A will continue to run, however CPS*AOV110, DRYWELL PURGE OUTLET OUTBOARD ISOL VLV closes (2) GTS Train B will automatically initiate Proposed Answer: A Explanation (Optional):
A. Correct - Because only one drywell trip unit failed, the primary containment vent valves only received a half isolation signal, (the vent valves are part of Group 9). The Group 9
isolation requires 2 out of 2 logic, (Le. two drywell trip units must actuate) in order for either the inboard or outboard containment vent valves to close. Since no isolation occurred, GTS Train A will remain running in containment vent mode. Also GTS train B only receives a half initiate signal per ARP 603101. With only a half isolation in, GTS train B will not start.
B. Incorrect - Although GTS train A will continue to run, GTS train B only received a half initiation signal so it will not start.
- c. Incorrect - AOV11 0 only received a half isolation signal, so it will not close. Two drywell pressure trip units would need to actuate in order to cause the valve shut.
D. Incorrect - AOV110 only received a half isolation signal, so it will not close. Two drywell pressure trip units would need to actuate in order to cause the valve shut and GTS Train B only received a half initiation signal so it will not auto start.

A. (1) lower faster (2) less negative B. (1) lower slower (2) more negative C. (1) lower slower (2) less negative D. (1) lower faster (2) more negative Proposed Answer: D Explanation (Optional):
A. Incorrect. Plausible if the question stem asked about throttling closed 4B, (decay heat removal valve) instead of 5B.
- 8. Incorrect. Plausible if the question stem asked about 48 being throttled open instead of 58 being throttled closed.
C. Incorrect. Plausible if 58 were throttled open instead of closed.
D. Correct. If 58 were throttled in the closed direction, less air would be recirculated back to the suction of the GTS train. This would result in more flow from both the R8 and the Drywell. With more flow coming from the drywell, drywell pressure would lower faster.
With more flow coming from the RB, then the R8 would get more negative.

Conditions are as follows:
- Suppression Pool Water Level is 233 feet
- Suppression chamber pressure is 5 psig and stable Which one of the following correctly completes the following statement?
If RHS A were placed in suppression chamber spray, _ _ __
A. suppression chamber pressure would not be affected because the suppression chamber spray ring is submerged.
B. suppression chamber and drywell pressure would lower at the same rate because the pressure suppression function of the primary containment has been lost.
C. the primary containment could potentially reach its design negative pressure capability of -4.7 psig because the drywell to suppression chamber vacuum breaker openings are submerged.
D. the drywell floor could potentially reach its design upward floor differential pressure of 10 psid because the drywell to suppression chamber vacuum breaker openings are submerged.
Proposed Answer: A Explanation (Optional):
A. Correct. The suppression chamber spray rings are at elevation 231 feet. Per NER-2M 039 (page 5-17), with the spray nozzles submerged, there will be no spraying action and suppression chamber pressure would be unaffected.
B. Incorrect. Although the pressure suppression function could be considered lost with the openings of the vacuum breakers submerged, it will not cause drywell and suppression chamber pressure to lower at the same rate. Additionally the suppression chamber
spray rings are submerged, so no spraying action will occur.
C. Incorrect. Plausible if the question asked about drywell sprays and conditions were given such that you were outside the drywell spray initiation limit.
D. Incorrect. Plausible if the question asked what would happen if you initiated drywell sprays as this is the reason you do not spray the drywell if the vacuum breaker openings are submerged.

Conditions are as follows:
- RPV pressure is stable at 900 psig
- The CRS has given the order to cooldown to cold shutdown conditions.
While cooling down the following is observed when pressure reaches 500 psig:
- Period indication is 100 seconds Which one of the following is required by N2-EOP-C5, Failure to Scram?
A. Stop the cooldown and STABILIZE pressure at 500 psig B. Stop the cooldown, RAISE pressure back to 900 psig and STABILIZE C. CONTINUE the cooldown at the CURRENT rate. If power goes above IRM range 6, then stop the cooldown D. CONTINUE the cooldown but at a LOWER rate. If power goes above IRM range 6, then stop the cooldown Proposed Answer: A Explanation (Optional):
A. Correct. Per N2-EOP-C5, if the reactor goes critical during cooldown, then pressure must be stabilized below 1052 psig. The EOP bases state that stabilizing pressure would be to pick a value close to the initial value but below the SCRAM setpoint. Since initial RPV pressure at the time of criticality is 500 psig, then stabilizing at 500 psig would be appropriate.
B. Incorrect. Pressure must be stabilized at 500 psig, not 900 psig.
C. Incorrect. The cooldown must be stopped. Plausible in that when IRMs are on range 6
the reactor can be considered shutdown per EOP-C5. With the reactor subcritical on range 6 or below, the CRS can give the order to cooldown.
D. Incorrect. The cooldown must be stopped. Plausible in that when IRMs are on range 6 the reactor can be considered shutdown per EOP-C5. With the reactor subcritical on range 6 or below, the CRS can give the order to cooldown.

Conditions are as follows:
- Power is at 15%
- Core flow is at 19.5 Mlbs/hr Per N2-S0P-29, Sudden Reduction in Core Flow, which one of the following actions is REQUIRED to be done first?
A. INSERT the first four CRAM rods B. PLACE the mode switch in shutdown C. MONITOR for core oscillations and SHIFT APRM recorders to fast speed D. TAKE manual control of FWLC and RAISE RPV water level to reset the runback Proposed Answer: B Explanation (Optional):
A. Incorrect. Plausible if a candidate mis-plots on the power to flow map, and finds himself in the OPRM dependent Stability region, then the immediate action is to insert the first four CRAM rods B. Correct. Plotting the power and core flow on the two loop power to flow map shows they are to the left of the Natural Circ Line, (Scram Region). N2-S0P-29 requires the reactor to be scrammed if the plant is operating in the Scram Region.
C. Incorrect. The required action is to insert a manual scram. Plausible in that the crew will monitor for core oscillations however shifting the APRM recorders to fast speed is only required in Attachment 1 and only if in the heightened awareness region and <3 OPRMS are operable.
D. Incorrect. The required action is to insert a manual scram. Plausible in that taking manual control of FWLC and raising RPV water level to reset the runback would normally be required.

Examination Outline Cross-reference: Level RO SRO Tier# 1 Group # 1 KIA # 295026 EK2.02 Importance Rating 3.6 KnowlE~dge of the interrelations between SUPPRESSION POOL HIGH WATER TEMPERATURE and the following: Suppression pool spray: Plant Specific Proposed Question: RO#44 The plant is shutdown following a LOCA. Conditions are as follows:
- RHS A and B are in suppression pool cooling
- Flow in RHS A and B systems are both at 7450 gpm with all flow going through the RHS heat exchangers
- The Service Water system is aligned for maximum flow through the RHS heat exchangers
- The CRS has determined suppression chamber sprays are needed and suppression pool cooling is still needed from both RHS systems.
Regarding the above:
(1) Per the Unit 2 Technical Specification Bases, how many RHS loops are required to be in Suppression Chamber Spray mode in order to compensate for potential steam bypass leakage into the Suppression Chamber AND (2) How will this impact the amount of heat removed from the Suppression Pool if Suppression Chamber Spray is initiated lAW EOP-6 Attachment 22, Containment Sprays?
A. (1) One loop (2) Amount of heat removed lowers B. (1) Two Loops (2) Amount of heat removed lowers C. (1) One loop (2) Amount of heat removed is approximately the same D. (1) Two Loops (2) Amount of heat removed is approximately the same
Proposed Answer: C Explanation (Optional):
A. Incorrect: Heat removal remains the same. Plausible if the candidate does not understand the RHS system configuration and the location of the now elements.
B. Incorrect: Only one loop is required. Additionally heat removal remains the same.
C. Correct: Per Tech Spec Bases B 3.6.2.4, in the event of a DBA, a minimum of one RHR suppression pool spray subsystem is required to mitigate potential bypass leakage paths and maintain the primary containment peak pressure below the design limits. If suppression chamber spray is initiated while in suppression pool cooling, then the flow rate through the heat exchanger remains the same. That is, after spray is initiated, flow through the heat exchanger is adjusted to 7450 gpm which is the flow rate while in suppression pool cooling.
D. Incorrect: Only one loop is required as described above.

Examination Outline Cross-reference: Level RO SRO Tier # 1 Group # 1 KIA # 295025 EK3.08 Importance Rating 3.5 Knowledge of the reasons for the following responses as they apply to HIGH REACTOR PRESSURE: Reactor/turbine pressure regulating system operation Proposed Question: RO#46 Given the following:
- A plant startup is in progress
- Reactor power is 26%
- Power ascension is on hold while engineering investigates a main generator winding issue
- The Load Limit has been lowered to limit generator load to 250 MWE
- The LOAD LIMIT LIMITING light is illuminated
- The MAXIMUM COMBINED FLOW LIMIT is set to control at 115%
Then ...
- A failure associated with Recirc Flow Control causes reactor power to rise by 10%.
Which one of the following is correct regarding the response of the Electrohydraulic Control System?
A. The control valves will not open any further. The bypass valves will open as required to control pressure.
B. The control valves will not open any further and the bypass valves will not open. The reactor will scram on high pressure.
C. Pressure will rise until the backup pressure regulator takes control and stabilizes pressure by opening the bypass valves.
D. The control valves will open an additional amount until the 250 MWE Load Limit is reached. The bypass valves will then open as required to control pressure.
Proposed Answer: A Explanation (Optional):
A. Correct: The control valves are already at their opening limit as evidenced by the Load Limit Limiting light being illuminated and will not open any further. Since the control valves cannot open the system will open the bypass valves to control the pressure rise.
A 10% power rise is within the capability of the bypass valves.
B. Incorrect: Although the load limit limits the control valves from opening it will not impact the bypass valves. Since the Max Combined Flow Limit is set to control at 115%, the bypass valves will open.
C. Incorrect: Both regulators will respond the same to the pressure rise. However the backup rise has a negative bias associated with its output that lowers its output to less than the in-service regulator. Since the output of the two regulators is sent to a high value gate the in-service regulator will remain in control.
D. Incorrect: The control valves are already at their opening limit as evidenced by the Load Limit Setting light being illuminated.

Conditions are as follows
- Drywell sprays were initiated when drywell temperature exceeded 250 degrees
- Drywell temperature and pressure are now lowering lAW N2-EOP-PC, drywell sprays are REQUIRED to be secured ...
A. before drywell pressure lowers to zero psig.
B. before the suppression chamber to drywell vacuum breakers lift.
C. when primary containment pressure goes negative relative to the secondary containment.
D. when drywell temperature and pressure lower to the BAD region of the Drywell Spray Initiation Limit curve.
Proposed Answer: A Explanation (Optional):
A. Correct: Per the NMP2 EOP Bases document: The operation of drywell sprays must be terminated by the time pressure decreases to 0 psig in the drywell to ensure that primary containment pressure is not reduced below atmospheric. Maintaining a positive pressure provides a positive margin to the negative design pressure of the primary containment (-4.7 psig). This action is directed by step N2-EOP-PC, DWT-4.
B. Incorrect: The vacuum breakers lifting is an expected occurrence when spraying the drywell. Plausible in that the vacuum breakers lifting is what keeps it from going necgative.
C. Incorrect: Orywell sprays must be secured before pressure drops to zero psig - i.e.,
before it goes negative.
O. Incorrect: This action is not specified. Plausible in that this is a requirement for initiating sprays. This limit is only applicable prior to spray initiation.

C. RPV Flooding entry is NOT required because water level readings are above Minimum Indicated Level values even though reference leg flashing IS occurring.
D. RPV Flooding entry is NOT required because water level readings are above Minimum Indicated Level values and reference leg flashing IS NOT occurring.
Proposed Answer: 0 Explanation (Optional):
A. Incorrect - RPV Flooding is NOT required based solely on being in the BAD region of Fig B Detail A. As long as NO evidence that instrument leg boiling is taking place exists.
B. Incorrect - RPV Flooding is NOT required based solely on being in the BAD region of Fig B Detail A. As long as NO evidence that instrument leg boiling is taking place exists.
C. Incorrect - There is NO evidence that instrument leg boiling is taking place and the instrument reads above Minimum Indicated Level (Table C) for the Wide Range.
D. Correct - Conditions are above DETAIL A's Saturation Temperature Curve of EOP-PC and RPV. Although elevated DWT and low RPV pressure can result in flashing there is no evidence of flashing on the Wide Range instruments. The Caution states that Level instruments can only be used if "there is NO evidence of instrument leg flashing AND the instrument reads above the Minimum Indicated Level (Table C). Since there is NO evidence that instrument leg boiling is taking place on the Wide Range and Wide Range level is above the minimum indicated value of 25 inches, level can be determined.

/ Draindown.
Which one of the following will occur if the drain down is terminated 2 feet below the reactor flange?
A. Exposure of the moisture separator which results in high radiation levels on the refuel floor.
B. Exposure of the steam dryer which results in higher radiation levels and potential high airborne activity.
C. Loss of minimum reactor level above the fuel which results in high radiation levels on the refuel floor.
D. Loss of reference leg for the shutdown level indication which results in a loss of Control Room level indication.
Proposed Answer: B Explanation (Optional):
A. Incorrect: The concern with lowering cavity level below the flange is exposing the steam dryer; the moisture separator is located below the steam dryer and is not exposed.
B. Correct: Inadequate monitoring of RPV level while performing drain down may result in exposing the steam dryer resulting in higher radiation levels and high airborne activity.
During a 2002 event at the Fitzpatrick plant, cavity level was lowered approximately 20 inches below the target level (top of RPV Flange). This exposed about 12 inches of the highly contaminated RPV Steam Dryer to the atmosphere for about 17 minutes and resulted in high radiation levels and contamination in parts of the reactor building.
C. Incorrect: The shutdown level indicator would not be appreciably affected by the draindown and is considered inoperable before and during the draindown.
D. Incorrect: There is no appreciable change in refueling floor radiation levels based on terminating the draindown 1 foot below the reactor flange.

Indications for ZONE 505 SW FPW-MOV172A, 172B on the sloping section of 2CEC*PNL849 show that the header is pressurized.
The Fire Brigade Leader reports that ZONE 505SW XFMR 2STX-XNS1 is in alarm at the Local Fire Panel.
Per EPIP-EPP-28, FIRE FIGHTING, the control room staff_....... (1:..L.)_ call this a CONFIRMED FIRE because (2)
A. (1) SHOULD NOT (2) suppression system actuation and flow CANNOT be confirmed.
B. (1) SHOULD NOT (2) the Fire Brigade Leader has not reported back to the control room that an actual fire exists.
C. ('1) SHOULD (2) the alarm at the Local Fire Panel indicates that there is an actual fire.
D. ('I) SHOULD (2) a fire has been detected and there is indication of suppression system activation with flow.
Proposed Answer: 0 Explanation (Optional):
A. Incorrect. Per EPIP-EPP-28, a fire can be called CONFIRMED provided the following exists; Fire Alarm/Annunciator and suppression system activation accompanied by actual flow or discharge. Having the electric fire pump start and ZONE 505 indicating the header is pressurized is sufficient to show suppression system activation with actual flow.
B. Incorrect. Although the FBL can call a fire confirmed, the control room staff can also call the fire confirmed if there are indications in the control room consistent with a Fire Alarm/Annunciator and suppression system activation accompanied by actual flow or discharge.
C. Incorrect. A local fire panel alarm is not sufficient to call a fire confirmed.
D. Correct. Per EPIP-EPP-28, a fire can be called CONFIRMED provided the following exists; Fire Alarm/Annunciator and suppression system activation which is indicated by annunciator 849227, FIRE DETECTED PNL 121 CB W CORRIDOR ELEVl261, accompanied by actual flow or discharge.

Conditions are as follows:
- Reactor pressure is 600 psig
- The following then occurs:
Time Event 07:05 2RDS-P1A ROD DRIVE PUMP trips on low suction pressure.
Operators are dispatched to swap RDS suction strainers 07: 10 Accumulator trouble alarms are received for withdrawn control rods 42-19,02-23, and 10-15.
07:15 A Plant Operator reports the following accumulator pressures to the control room:
42-19: 970 psig 02-23: 910 psig 10-15: 920 psig Per N2-S0P-30 Control Rod Failures, when must the mode switch be placed in SHUTDOWN?
A. 07:10 B. 07:15 C. 07:25 D. 07:30 Propos'ed Answer: B Explanation (Optional):
A. Incorrect: A scram is required at 07: 15. Accumulator trouble alarms annunciate at 1000
psig accumulator pressure. In order to call an accumulator inoperable, pressure must be <940 psig, which requires a report from the field. Plausible in that because RPV pressure is <900 psig, a scram is required immediately after determining at least one accumulator for a withdrawn control rod is inoperable. If the candidate incorrectly correlates an accumulator trouble alarm to an inoperable accumulator, then they could choose this distracter.
B. Correct. A loss of a running RDS pump will cause charging water header pressure to go immediately <940 psig. At 07: 15, a report from the PO gave two accumulator pressures <940 psig which makes them inoperable. Per the N2-S0P-30 override, a scram is required immediately if these conditions exist.
C. Incorrect. A scram is required at 07: 15. Plausible in that if the candidate does not remember to take into account that RPV pressure is <900 psig, they may choose to apply the charging header pressure <940 psig for 20 minutes which would require placing the mode switch in shutdown at 07:25.
D. Incorrect. A scram is required at 07: 15. Plausible in that if the candidate does not remember to take into account RPV pressure is <900 psig and they do not understand that accumulator trouble alarms do not immediately require declaring an accumulator inoperable then they may choose this distracter Technical Reference(s): SOP-30, Control Rod Failures (Attach if not previously provided)

Proposed Question: RO#61 The plant is at 100% power. Conditions are as follows:
- A spurious turbine trip occurs
- Annunciator 851539, REAC FEED PMP 1A11B/1C SUCTION PRESS LOW/LO-LO alarms
- Feed pump suction pressure is 200 psig and stable Which one of the following (1) describes the response of the feedwater control system and (2) per N2**0P-3 Condensate and Feedwater System, what is the reason for this response?
A (1) The high pressure high flow control valves (LV 10A, B & C) close and the controllers shift to MANUAL.
(2) To minimize the possibility of Feed Pump cavitation.
B. (1 ) The high pressure high flow control valves (LV 10A, B & C) close and the controllers shift to MANUAL.
(2) To prevent feedwater pump runout.
C. (1) The high pressure high flow control valves (LV 10A, B & C) are limited to a maximum of 70% open.
(2) To minimize the possibility of Feed Pump cavitation.
D. (1 ) The high pressure high flow control valves (LV 10A, B & C) are limited to a maximum of 70% open.
(2) To prevent feedwater pump runout.
Proposed Answer: C Explanation (Optional):
A Incorrect: The logic output clamps the high pressure high flow control valves (LV 10A, B
& C) to a maximum of 70% open (48% flow).
B. Incorrect: lAW N2-0P-03, The Feed Pump Flow Limiter Logic minimizes the possibility of Feed Pump cavitation. The logic output clamps the high pressure high flow control valves (LV 10A, B & C) to a maximum of 70% open (48% flow).
C. Correct: lAW N2-0P-03, The Feed Pump Flow Limiter Logic minimizes the possibility of Feed Pump cavitation anytime a low Feed Pump suction pressure is present concurrently with a Main Turbine trip. With this logic engaged, flow is limited through the Feed Pump thus restoring NPSH at the pump suction. The logic is automatically bypassed when either initiating condition is clear. When actuated, the logic output clamps the high pressure high flow control valves (LV 10A, B & C) to a maximum of 70% open (48% flow).
D. Incorrect: The Feed Pump Flow Limiter Logic minimizes the possibility of Feed Pump cavitation.

- Reactor Building differential pressure changes from -0.6" to -0.25" WG Which one of the following identifies the automatic response of the Reactor Building Ventilation system and the Standby Gas System (GTS) to the change in Reactor Building differential pressure?
HVR MOD17A1B, VENT SUPPLY AIR RECIRC DAMPER RESPONSE GTS RESPONSE A. Modulates Open Starts B. Modulates Close Starts C. Modulates Open Remains in Standby D. Modulates Close Remains in Standby Proposed Answer: C Explanation (Optional):
A. Incorrect - GTS will not auto start on high (less negative) building dp. Plausible in that if a GTS initiation signal is present the standby GTS will start on low dp.
B. Incorrect: GTS will not auto start on high (less negative) building dp. Plausible in that if a GTS initiation signal is present the standby GTS will start. Additionally, HVR MOD17AlB bypasses the supply fans discharge back to the fan intake. The damper closing would bypass less flow, increasing the supply to the building and causing pressure to rise even further in the building.
C. Correct: HVR MOD17AlB will modulate open to reduce intake air flow to the reactor building. This will result in driving the differential pressure back in the negative direction via the exhaust fans. GTS will not start on high (less negative) building dp.
D. Incorrect: HVR MOD17AlB bypasses the supply fans discharge back to the fan intake.

C. Only one area is affected by elevated radiation levels. A manual scram IS required but an RPV Blowdown is NOT required.
D. Two areas are affected by elevated radiation levels. A manual scram IS required AND an RPV Blowdown IS required.
Proposed Answer: D Explanation (Optional):
A. Incorrect: Two areas are affected. Plausible in that both areas are on the same elevation.
B. Incorrect: A scram is required via EOP-RPV because a primary system is discharging.
Plausible in that this would be the correct answer if the candidate does not consider WCS as a primary system.
C. Incorrect: Two areas are affected. Additionally, a blow down is required. Plausible in that if the candidate considers that only one area is impacted and correctly determines that a primary system is discharging, this would be the correct answer.
D. Correct: Per the TMG page 39, each area radiation monitor is treated as a separate area. Since RMS2A and 2B are reading above Max Safe Values, then 2 areas are affected. Because WCS (Reactor Water Cleanup) is a primary system entry into N2 EOP-RPV is required via EOP-SC, step 8, which will require a scram. Because 2 areas are above Max Safe a Blowdown is required by EOP-SC Step SC-10.

- Reactor power is 18%
- A Main Condenser leak develops
- Condenser vacuum rapidly lowers to 8.0 inches Hg.
With no operator action, which one of the following describes the conditions that would exist following this event?
The reactor has ...
A. scrammed and decay heat is being removed using the SRV's.
B. scrammed and decay heat is being removed by Turbine Bypass Valves.
C. NOT scrammed and reactor pressure is being controlled by Turbine Bypass Valves, D. NOT scrammed and reactor pressure is being controlled by the Turbine Control Valves.
Proposed Answer: A Explanation (Optional):
A. Correct: When condenser vacuum reaches is 22.1 inches Hg the Main turbine will trip, At 8.5 inches Hg the MSIV's will shut. At 18% power the Mode Switch will be in run which will cause a Rx scram when the MSIV's shut. The Bypass valves will not fail shut on low vacuum but with the MSIV's shut they will not provide for pressure control.
Therefore pressure will be controlled using the SRVs.

Ability to determine and/or interpret the following as they apply to HIGH DRYWELL TEMPERATURE: Drywell pressure Proposed Question: SRO # 76 The plant is shutdown following a LOCA. Conditions are as follows:
- Orywell temperature is 330°F and slowly rising
- Orywell pressure is 8 psig and slowly rising
- Suppression Pool Water Level is 220 feet and stable
- All drywell unit coolers tripped when drywell pressure exceeded 1.68 psig
- A and B Recirc pumps have been tripped due to high motor temperatures Which one of the following actions should be taken to control DRYWELL TEMPERATURE?
IK IDrywell Spray Initiation Limit 350 tL I~
1 250 1 200 160 Drywen Pressure (psig)
A. Enter N2-EOP-C2, RPV Blowdown and blowdown the reactor.
B. Spray the drywell using RHS A or B per N2-EOP-6, Attachment 22, Containment Sprays.
C. Re-start all available drywell cooling per N2-EOP-6 Attachment 24, Operation of Orywell Cooler Units with LOCA Signal.
D. Vent and purge the containment per N2-EOP-06 Attachment 21, Containment Venting, and Attachment 25, Containment Purging.
Proposed Answer: A Explanation (Optional):
A. Correct. Per N2-EOP-PC, because suppression pool water level is above 217 feet, the drywell cannot be sprayed. Additionally. since drywell temperature is above 250°F, the drywell unit coolers cannot be operated. Since both mitigation strategies in EOP-PC for lowering drywell temperature cannot be used and drywell temperature continues to rise, then Drywell temperature cannot be restored and MAINTAINED <340°F so a blowdown is required. Additionally, per the EOP BASES, "A determination that drywell temperature cannot be restored and maintained below 340°F may be made when, before, or after temperature actually reaches the value" B. Incorrect. Since suppression pool water level is >217 feet, drywell sprays cannot be used. Plausible in that this would be an allowable if level were <217 feet.
C. Incorrect. Since Drywell temperature is >250°F, the drywell unit coolers cannot be operated. Plausible in that if drywell temperature were <250°F, then the drywell unit coolers could be operated.
D. Incorrect - These attachments are used for venting the primary containment to maintain pressure below the PCPL and for hydrogen gas control. They are not authorized for use in attempts to maintain containment temperature as their use would result in a release and the structural integrity of the containment is not immediately threatened.

D. Enter N2-EOP-RPV, RPV Control and insert a manual scram signal. If rods to not insert, enter N2-EOP-C5, Failure to Scram.
Proposed Answer: B Explanation (Optional):
A. Incorrect. Plausible in that entry into N2-S0P-21 is required due to the turbine trip and placing the mode switch to shutdown is required only if the turbine did not trip and power is >25%.
B. Correct: Entry into N2-S0P-21 is required based on the turbine tripping. Entry into
SOP-97 is required because RPS A has tripped. SOP-97 directs checking control rod positions for drifting control rods. No EOP entry conditions have been exceeded based on the information provided. RPS "An should not have tripped because the reactor scram on turbine trip signal is bypassed less than 30% based on turbine 1sl stage pressure.
C. Incorrect. Entry into SOP-21 is required. Plausible in that if RPS B failed to deenergize, it would be considered an RPS failure. Entry into SOP-97 is required, but not to trip RPS B. Entry into the EOP-RPV would be required if after the scram level lowered to
<159 inches.
D. Incorrect: An EOP entry condition has not been exceeded. Plausible if the candidate believes that RPS should have tripped at this power level following the turbine trip. In that case a manual scram would be required.

Examination Outline Cross-reference: Level RO SRO Tier# 1 Group # 1 KJA# 700000 AA2.09 Importance Rating Ability to determine and/or interpret the following as they apply to GENERATOR VOLTAGE AND ELECTRIC GRID DISTURBANCES: Operational status of emergency diesel generators.
Proposed Question: SRO # 78 The plant is operating at rated power. Conditions are as follows:
- The determination is made that the primary Emergency Starting Circuit for the Division I EDG has failed.
- The diesel's secondary Emergency Starting Circuit is confirmed to be functioning Regarding the status of the Division 1 Diesel and its ability to respond to a loss of offsite power, which one of the following is correct?
The dieseL ..
A. remains operable because the secondary circuit is functioning.
B. is inoperable because the primary circuit has failed but is available because the secondary circuit is functioning.
C. is inoperable and not available because the primary circuit has failed and the secondary circuit is not capable of starting the diesel.
D. is inoperable because the primary circuit has failed but can be made operable via a compensatory measure of stationing an operator to manually start the diesel if required.
PropoSE!d Answer: B Explanation (Optional):
A. Incorrect - The Diesel is inoperable. Per N2-0P-100A, the diesel should be declared inoperable if the primary starting circuit fails. Plausible in that the secondary circuit will start the engine should an emergency start signal be received.
B. Correct - The Diesel is inoperable. Per N2-0P-100A, the diesel should be declared inoperable if the primary starting circuit fails. Both circuits are independently capable of starting the Diesel in the Emergency Mode and both circuits have this capability tested every 18 months {24 months}. The main difference between the two circuits is that the
Primary Circuit has additional circuitry to control the Governor in droop mode (Parallel Mode) as well as Isochronous Mode and to switch the Governor out of Parallel Mode into Isochronous Mode on a Loss of Offsite Power. The Redundant Circuit can control the Governor only in Isochronous Mode. Thus if the Primary Circuit is lost, the Governor will not operate in Parallel Mode. Although the secondary start circuit is capable of starting the Diesel independent of the primary start circuit, the Diesel should be declared inoperable if the primary start circuit is inoperable. This is because not all required portions of the secondary start circuit are surveiled. Since the Diesel is capable of auto starting, it can be declared available per CNG-OP-1.01-2002, Operations Shift Turnover and Relief C. Incorrect - The Diesel is inoperable. Per N2-0P-100A, the diesel should be declared inoperable if the primary starting circuit fails. Plausible in that the secondary circuit will start the engine should an emergency start signal be received and there is an operable but degraded classification in CNG-OP-1.01-1002. However this condition would not meet the definition of this classification is because not all required portions of the secondary start circuit are surveiled as discussed below.
D. The Diesel is inoperable. Plausible in that CNG-OP-1.01-1002 addresses the use of comp measures. However a comp measure can only be used to return an inoperable component to an operable but degraded status.

C. An Alert EAL was first exceeded at 00: 15.
A Site Area Emergency EAL was not exceeded until 00:45.
D. An Alert EAL was first exceeded at 00:15.
A Site Area Emergency EAL was not exceeded until 00:30.
Proposed Answer: C Explanation (Optional):
A. Incorrect - Although UE EAL 6.2.1 was exceeded at time 00:15 due to the initial loss of offsite, Alert EAL, 6.1.3 was also exceeded at 00: 15 when the only source of power was the Div 1 diesel and this condition had existed for 15 minutes. Plausible if the candidate focuses on the fire in the diesel room which is also an Alert based on EAL 8.2.2 B. Incorrect - Alert EAL, 6.1.3 was exceeded at 00:15 when the only source of power was the Div 1 diesel and this condition had existed for 15 minutes. A Site Area EAL was not exceeded until 00:45. Plausible if the candidate does not realize that the loss of all AC must exist for 15 minutes before the EAL is exceeded.
C. Correct - Alert EAL, 6.1.3 was exceeded at 00:15 when the only source of power was the Div 1 diesel and this condition had existed for 15 minutes. When the Div 1 diesel was lost at time 00:30, the 15 minute clock started for Site Area Emergency EAL 6.1.4 due to a loss of all AC power. 15 minutes later, at time 00:45, the EAL was exceeded.
D. Incorrect - The Site Area Emergency was not exceeded until 00:45.

Emergency Procedures I Plan: Knowledge of the specific bases for EOPs. (SCRAM Conditions Present and Reactor Power Above APRM Downscale or Unknown)
Proposed Question: SRO # 80 The plant was manually scrammed due to an un-isolable RCIC steam leak in the Reactor Building. Conditions are as follows:
- Reactor power is 6%
- Reactor level is 180 inches and stable
- RRCS failed to automatically and manually initiate
- MSIVs are open and reactor pressure is stable on the turbine bypass valves
- One Reactor Building area temperature is above its Max Safe Value
- A second Reactor Building area temperature is rising but below its Max Safe Value.
Which one of the following is (1) the REQUIRED action and (2) per NER-2M-039, EOP BASES, what is the bases for this action?
A. (1) lAW N2-EOP-C2 RPV Blowdown, open 7 ADS valves and depressurize the RPV (2) This step is designed to reduce the driving head of the leak and minimize heat addition to the primary containment B. (1) lAW N2-EOP-C5, anticipate the RPV Blowdown and rapidly depressurize the RPV using the main turbine bypass valves (2) This step is designed to reduce the driving head of the leak and minimize heat addition to the primary containment C. (1) lAW N2-EOP-C5, terminate and prevent all injection except from Boron, CRD and RCIC and lower RPV Level. Let level drop to below 100 inches (2) This step is designed to uncover the feedwater sparger to minimize core oscillations D. (1) lAW N2-EOP-C5, terminate and prevent all injection except from Boron, CRD and RCIC and lower RPV Level. Let level drop to below 100 inches (2) This step is designed to lower reactor power by reducing natural circulation Proposed Answer: C Explanation (Optional):
A. Incorrect - EOP-SC directs that RPV Slowdown be entered WHEN two areas are above their Max Safe Operating Values. Only one area is above the max safe value.
S. Incorrect - Anticipating the RPV blow down is not authorized by the EOPs during failure to scram conditions. Plausible in that this action is authorized in N2-EOP-RPV.
C. Correct - With power above 4%, the Level Leg of N2-EOP-C5 directs lowering level to below 100 inches. Per the EOP bases document, steps L-5 and L-9 are designed to prevent or mitigate the consequences of any large irregular neutron flux oscillations induced by neutronic I thermal-hydraulic instabilities by lowering RPV water level sufficiently below the elevation of the feedwater sparger nozzles (100 inches). This places the feedwater spargers in the steam space providing effective heating of the relatively cold feedwater and eliminating the potential for high core inlet subcooling. For conditions that are susceptible to oscillations, the initiation and growth of oscillations is principally dependent upon the subcooling at the core inlet; the greater the subcooling, the more likely oscillations will commence and increase in magnitude.
D. Incorrect - The reason described in the distracter is for the EOP action to lower and I:;ontrol level to lower power by reducing natural circulation. This step is taken when heat addition to the primary containment is occurring, (Le. 110°F suppression pool temperature). Plausible in that this is a common misconception with operators.

A. HCTL is being exceeded. Enter N2-EOP-C2, RPV Slowdown and blowdown the RPV.
S. HCTL is NOT being exceeded. Lower RPV pressure as necessary to prevent exceeding HCTL.
C. HCTL is being exceeded. Lower RPV pressure to restore and maintain RPV pressure to within HCTL. RPV blowdown is not required.
D. HCTl is NOT being exceeded. Place RHR "B" in suppression pool cooling and maximize cooling to both Heat Exchangers to lower suppression pool temperature to prevent exceeding HCTL.
Proposed Answer: A Explanation (Optional):
A Correct. Since HCTl is being exceeded, the action per N2-EOP-PC is to enter EOP-C2 and blowdown the reactor. Step SPT-6 of EOP-PC does not allow you restore and maintain, so if the limit is exceed, a blowdown is required.
B. Incorrect. HCTl is being exceeded. Plausible in that if HCTl were not being exceeded, lowering RPV pressure would be the right action.
C. Incorrect. Plausible if the candidate thinks that the parameters associated with HCTL can be restored and maintained vice just maintained.
D. Incorrect. HCTl is being exceeded. Plausible in that this is a required action per N2 EOP-PC per step SPT-3.

Ability to determine and/or interpret the following as they apply to HIGH REACTOR WATER LEVEL: Steam flowlfeedflow mismatch Proposed Question: SRO # 83 The plant is operating at 80% power. Conditions are as follows:
- Feed Pumps A and B are in service
- All Narrow Range Level Indicators indicate 188 inches and slowly rising
- INDICATIONS for FWLC are as follows:
- ALL four Main Steam Line Flows are 3 X 106 Ibm/hr and stable
- The outputs of the Master Controller and the Individual MIA Controllers are ALL observed to be 43% and slowly rising Based on the above indications and in addition to taking manual control of FWLC per N2-S0P 06; (1) What additional action is required?
AND (2) Why is that action necessary?
A. (1) lAW N2-0P-3, Condensate and Feedwater System, shift to Single Element Control AND return FWLC to auto.
(2) "A" Feedwater Header Flow instrument is failing upscale.
B. (1) lAW N2-0P-3, Condensate and Feedwater System, shift to Single Element Control AND return FWLC to auto.
(2) "B" Feedwater Header Flow instrument is failing downscale.
C. (1) lAW N2-S0P-06, Feedwater System Failures, Attachment 2, change MOV 47A to a throttle valve and reduce flow through LV10A.
(2) LV1 OA is locked up and drifting open.
D. (1) lAW N2-S0P-06, Feedwater System Failures, throttle "A" Feedwater Header flow with 2FWS*MOV21A, FD WTR TO REACTOR OUTBD ISOL VLV.
(2) LV10A is locked up and drifting open.
Proposed Answer: 8 Explan.ation (Optional):
A. Incorrect - The "A" feedwater instrument is responding normally. If this instrument was failing upscale, FWLC would think that feed flow was greater than steam flow and close down on LV108 and C, causing actual level to lower. Plausible in that "A" line flow is reading higher than "8" line flow.
- 8. Correct - The "8" Feedwater Flow sensor is failing downscale. This is causing a sensed
'feed flow steam flow mismatch. FWLC is responding to the false mismatch by opening LV1 OA and 8 as evidenced by the increasing output signals. Since actual feed flow was already equal to steam flow, actual level begins to rise. N2-S0P-06, Feedwater System Failures, 4th override of the subsequent actions directs that if a feed flow or steam flow instrument is malfunctioning, then FWLC is to be shifted to single element control.
C. Incorrect - LV10A is not locked up. Plausible in that these valves when locked up do have a tendency to drift and "A" feed flow is higher than "8" feed flow. However this cannot be the cause as both feed flows would be increasing if the valve was locked up since the feed pumps discharge into a common header before splitting into the two headers downstream of the heaters. Additionally FWLC would respond by attempting to Glose down on LV1 OA and 8, which is not the case since the output Signals from the controllers are increasing.
D. Incorrect - LV10A is not locked up. Plausible in that these valves when locked up do have a tendency to drift and "A" feed flow is higher than "8" feed flow. However this cannot be the cause as both feed flows would be increasing if the valve was locked up since the feed pumps discharge into a common header before splitting into the two headers downstream of the heaters. Additionally FWLC would respond by attempting to close down on LV10A and 8, which is not the case since the output signals from the controllers are increasing.

Proposed Question: SRO # 84 The plant is at rated power. Conditions are as follows:
- An inadvertent isolation signal has caused the Outboard CCP Containment Isolation valves to the drywell cooling system to isolate
- The isolation signal CANNOT be reset
- Based on the nature of the malfunction, the CRS has declared the Outboard CCP Containment Isolation valves INOPERABLE per TS 3.6.1.3 lAW with N2-S0P-60, Loss of Drywell Cooling ....

Explanation (Optional):
A. Correct - Only the DRYWELL UNIT COOLER WTR DIV I LOCA OVERRIDE is required.
TS 3.6.1.3 Action A states that for "One or more penetration flow paths with one PC IV inoperable except due to leakage not within limit" then the required action is to isolate the path within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. With the Div 1 switch in the override position, the outboard isolation valves will not close.

B. Incorrect - The plant shutdown must commence no later then16 hours from the time switches are placed in override. Plausible in that this would be true if the penetration was associated with a "Closed system". CCP is not a Closed system.
C. Incorrect - Use of the UNIT COOLER FANS GR1 LOCA OVERRIDE switch is not required. This switch overrides the trip signal to the cooler fans if the CCP isolation valves are not open.
D. Incorrect - Use of the UNIT COOLER FANS GR1 LOCA OVERRIDE switch is not required. This switch overrides the trip signal to the cooler fans if the CCP isolation valves are not open.

A. (1) CSL pump breaker trips.
(2) In accordance with N2-EOP-RPV, RPV Control; inhibit ADS and lineup alternate injection systems as needed to maintain RPV water level greater than -14".
B. (1) CSL pump breaker trips.
(2) Direct an operator to manually close the CSL pump breaker using N2-ELU-01, Walkdown Order Electrical Lineups and Breaker Operations and re-establish CSL injection.
C. (1) CSL continues to operate.
(2) In accordance with N2-EOP-RPV, RPV Control; maintain injection by operating the CSL system as needed to maintain RPV water level between 159.3" and 202.3".
D. (1) CSL continues to operate.
(2) In accordance with N2-S0P-04, Loss Of DC Power, immediately de-energize 2ENS SWG-101. In accordance with N2-EOP-RPV, RPV Control; inhibit ADS and lineup alternate injection systems as needed to maintain RPV water level greater than -14".
Proposed Answer: C Explanation (Optional):
A. Incorrect - The CSL pump breaker will remain closed. CSL injection may continue and RPV water level can be maintained and controlled above -14" therefore there is no requirement to inhibit ADS and lineup alternate injection systems.
B. Incorrect - The CSL pump breaker will remain closed.
C. Correct - The loss of DC power to the CSL system will remove power from 4 KV breaker, this will remove protective tripping and remote breaker operation. The breaker will remain closed and CSL will continue to inject. lAW N2-EOP-RPV and N2-0P-32 RPV water level can be controlled by opening and closing CSL*MOV1 04 locally.
D. Incorrect - Plausible in that the switchgear is in service without any bus protection.
However, per SOP-04 discussion item 5.2, it is recommended to NOT shed AC loads on a loss of divisional DC power. A probability assessment has been performed and the results support this recommendation. The recovery of DC power should be the highest priority for the operators. IF the loss of divisional DC power is for an extended period of time (>12 hrs), THEN, it may be desirable to shed the AC loads AND de-energize the associated emergency switchgear. Additionally Although OP-32 directs stopping the pump when injection is not required, the pump may only be manually started at the breaker once because with a loss of DC power the charging motor cannot recharge the closing springs.

Proposed Answer: D Explanation (Optional):
A Incorrect. Since TK1A is reading <330 psig, per N2-0P-61 B, GTS train A is considered inoperable. Since GTS 8 Fan tripped, then GTS Train B is also considered inoperable.
With both trains inoperable, TS Bases 3.6.4.3, Condition 0.1 states that the GTS system is not capable of supporting its designed Tech Spec function and TS 3.0.3 must be entered. Plausible in that if the candidate does not know that <330 psig will inop the GTS train, then this answer could be considered correct.
B. Incorrect. Plausible in that the candidate may know both trains are inoperable, but may think that since GTS A is still running that it is capable of performing its Tech Spec Function.

C. normal AC power to the Division I UPS. No Technical SpeCification actions required.
D. maintenance AC power to the Division I UPS. No Technical Specification actions required.
Proposed Answer: C Explanation (Optional):
A. Incorrect. Although a loss of normal AC could cause these indications, per the TS bases, the loss of the normal AC power supply does not require the UPS to be declared inoperable.
B. Incorrect. A loss of maintenance AC would not cause the UPS to be on battery power, (Le. 852124 in alarm).
C. Correct. The loss of normal AC (2EJS*PNL 1OOA) , would cause a loss of AC power to the Battery charger resulting in annunciator 852108, (DC bus voltage <131 VDC).
Additiona"y, with the loss of normal AC to UPS 2A12C, 852116 alarms and the UPS goes to the battery supply which causes 852124 to alarm. Since the UPS is still operating on battery power, and no indications are given that there is anything else wrong with the battery (other than not being on the charger), the UPS is still operable per the TS bases and so no Technical Specification actions are required.
D. Incorrect. A loss of maintenance AC would not cause the UPS to be on battery power, (I.e. 852124 in alarm)

Proposed Answer: 0 Explanation (Optional):
A. Incorrect: Insert and withdraw blocks will be applied when withdraw of the next step is commenced, as the RWM will not allow an operator to make an error. Plausible in that the RWM will allow operation with two insert errors.
B. Incorrect: Insert and withdraw blocks will be applied when withdraw of the next step is commenced, as the RWM will not allow an operator to make an error. Plausible in that the RWM will allow operation with two insert errors. In addition the rod must be disarmed within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
C. Incorrect: It is not necessary to station a second operator if the RWM is bypassed because more than 12 rods are withdrawn (TS 3.3.2.1 Condition C). At 4% power, many more than 12 rods have been withdrawn.
O. C,orrect: Insert and withdraw blocks will be applied when withdraw of the next step is commenced because the rod will be identified as in insert error.

Proposed Question: SRO Question # 92 N2-EOP-C5, Failure to Scram is being executed. Plant conditions are as follows:
- Reactor Power is 26%
- Reactor Level is 180 inches
- Recirc Pumps are running in Fast Speed Per GAI-OPS-20 Transient Mitigation Guidelines, which one of the following is correct regarding the sequencing of actions involving operation of the Recirculation System and the reason for it?
The SRO should prioritize ....
A. reducing Recirc to minimum over lowering RPV level below 100 inches to prevent Level 8 trips.
B. lowering RPV level below 100 inches over reducing Recirc to minimum to prevent Level 8 trips.
C. reducing Recirc to minimum over lowering RPV level below 100 inches to increase margin to HCTL.
D. lowering RPV level below 100 inches over reducing Recirc to minimum to increase margin to HCTL.
Proposed Answer: B Explanation (Optional):
A. Incorrect. Plausible, because if power were <4%, the Recirc system would be reduced to minimum and level would not be lowered.
B. Correct. Per GAI-OPS-20, when the SRO is faced with either lowering RPV level or reducing Recirc to minimum, they should choose to lower RPV level because of the potential for level transients tripping the turbine or feed pumps (L8).
C. Incorrect. Increasing the margin to HCTL is not the reason for prioritizing lowering level over Recirc. Plausible in that if heat were being added to the suppression pool, lowering level is a quicker method of lowering power than reducing recirc to minimum.
This would reduce heat input into the suppression pool and increase your margin to HCTL.
D. Incorrect. Increasing the margin to HCTL is not the reason for prioritizing lowering level over Recirc. Plausible in that if heat were being added to the suppression pool, lowering level is a quicker method of lowering power than reducing recirc to minimum.
This would reduce heat input into the suppression pool and increase your margin to HCTL.

A. lincorrect. Entry into N2-EOP-CS is required first before entry into N2-EOP-C4.
Plausible if the candidate does not know that the override for entry into CS is before the
override for C4 and the action once in C4 is to terminate and prevent, not open 7 ADS valves.
B. Incorrect. Entry into N2-EOP-C5 is required first before entry into N2-EOP-C4.
Plausible if the candidate does not know that the override for entry into C5 is before the override for C4.
C. Incorrect. The requirement to place HPCS in PTL and inhibit ADS comes before the override to exit C5 and enter C4. Additionally, once in C4, the operators must terminate and prevent before opening 7 ADS valves.
D. Correct. The override to exit N2-EOP-RPV and enter C4 is found in the level leg of EOP-RPV. Because reactor power is unknown, the SRO must exit EOP-RPV and enter C5 before the level leg of EOP-RPV is executed. Once in C5, the actions to place HPCS in PTL and inhibit ADS come before the override to exit C5 and enter C4. Once C4 is entered, the SRO must terminate and prevent all injection except CRD, RCIC, and Boron before opening 7 ADS valves.

Examination Outline Cross-reference: Level RO SRO Tier# 3 Group # 4 KIA # G4 2.4.9 Importance Rating 4.2 Emergency Procedures I Plan: Knowledge of low power I shutdown implications in accident (e.g., loss of coolant accident or loss of residual heat removal) mitigation strategies.
Proposed Question: SRO Question # 98 The plant is in Mode 4. Conditions are as follows:
- Reserve Station Transformer A is being powered by Line 5
- Reserve Station Transformer B is being powered by Line 6
- RPV Level is 184 inches
- Recirc Pump B is in slow speed
- Recirc Pump A is tagged out for maintenance.
- RHS B is operating in shutdown cooling mode Then a loss of Line 6 occurs. Division" EDG immediately trips on overspeed.
Which one of the following actions are required?
A. Do not attempt to restart the Division II EDG. Lineup for Alternate shutdown cooling, Preferred Lineup per N2-S0P-31, Loss of Shutdown Cooling B. Do not attempt to restart the Division" EDG. Within one hour of the loss of Line 6, raise RPV level to 227 to 243 inches per N2-S0P-31, Loss of Shutdown Cooling.
C. Reset the overs peed device and attempt to restart the Division" EDG per N2-S0P-03, Loss of AC Power. If the Division " EDG starts and powers its bus, then restart RHS B in shutdown cooling mode per N2-S0P-31, Loss of Shutdown Cooling.
D. Reset the overs peed device and attempt to restart the Division II EDG per N2-S0P-03, Loss of AC Power. If the Division II EDG fails to start, then within one hour of the loss of Line 6, raise RPV level to 227 to 243 inches per N2-S0P-31, Loss of Shutdown Cooling.
Proposed Answer: B
Explanation (Optional):
A. Incorrect. Since Line 6 is deenergized and Div II EDG is not powering its bus, RHS B is not available. The question stem gives RHS A out of service. Per N2-S0P-31, Attachment 1, RHS A or B are needed in order to establish alternate shutdown cooling.
B. Correct. Since the EDG tripped on overspeed, it cannot be started per N2-S0P-03. On the loss of line 6, Recirc Pump B trips. With a loss of shutdown cooling and RPV level
<227 inches, then within one hour, the operators must raise level to between 227 and 243 inches per N2-S0P-31.
C. Incorrect. N2-S0P-03 does not allow restarting an EDG with an overs peed condition in.
D. Incorrect. N2-S0P-03 does not allow restarting an EDG with an overspeed condition in.
