Description:==

When Control rod 30-31 reaches position 10, the white "Rod Out" block light will be extinguished since the rod is past its intended 08 position. IAW 34AB-C11-004-1, Mispositioned Control Rods, at Table after 4.4 when less than the LPSP of 20.6% RTP and one control rod drifting out, entering the scram procedure is required.

The "A" distractor is plausible if the applicant confuses exactly what makes the "Rod Out" block light illuminate, whether it illuminates when a block exists or is extinguished when a block exists. The second part if the applicant thinks power is above the LPSP, which would require the applicant to enter section 4.5 and NOT scram.

The "B" distractor is plausible since the first part is correct and the second if the applicant thinks power is above the LPSP, which would require the applicant to enter section 4.5 and NOT scram.

The "D" distractor is plausible if the applicant confuses exactly what makes the "Rod Out" block light illuminate, whether it illuminates when a block exists or is extinguished when a block exists. The second part is correct.

2011 Hatch 301 DRAFT

==

Description:==

The Position Indicators transmit electrical signals to provide remote indication of control rod position and CRD temperature. The indicator probes consist of a plug, receptacle, thermocouple, and a switch support with 53 switches. The switches are magnetic reed switches and are normally open. They are closed (made-up) by the magnet on the bottom of the drive piston.

Switch 49 provides Red "Full Out" indication on the full core display and is located at position "48. Rod position will indicate "48". Switch 50 is 2 inches below Switch 49. This means that it is 2 inches below the point where the Control Rod should have backseated. The switch can only close if uncoupling of the control rod has occurred and will provide the Control Room operator with an annunciator. When in this condition the rod position will NOT indicate and the "Full Out" indication will NOT be lit.

The "A" distractor is plausible if the applicant thinks that switch 49 will indicate position 49 and the second if the applicant remembers that this switch normally illuminates the Red Full-Out light.

The "B" distractor is plausible if the applicant thinks that switch 49 will indicate position 49 and the second part is correct.

The "C" distractor is plausible since the first part is correct and the second if the applicant remembers that this switch normally illuminates the Red Full-Out light.

A. Incorrect - See description above.

B. Incorrect - See description above.

C. Incorrect - See description above.

Description:==

Under the following conditions, the RWM display will automatically turn itself on or off.

a front panel key is pressed, or a change of power level occurs within LPSP/LPAP, or a change of MODE occurs on RWM, or a change in the SELF-TEST status occurs Reactor Scram (If either K14A or K14C AND K14B or K14D de-energize, THEN RWM display will Auto turn on)

K14A or K14C AND K14B or K14D will NOT be de-energized since ALL "White" RPS Scram Group lights remained ILLUMINATED. The OATC will be required to depress the confirm shutdown screen in order to determine confirmation status.

CONFIRM SHUTDOWN: This function determines if all control rods are fully inserted into the core and if shutdown confirmation criteria has been satisfied.

Shutdown Confirmation Criteria: If all rods are at or inserted past position N then shutdown is confirmed. N is defined in the SET PARAMETERS function as rod position "02". If shutdown is confirmed, then SHUTDOWN: YES will be displayed, otherwise SHUTDOWN: NO will be displayed. Since the Shutdown Confirmation screen indicates "Yes", then all rods are at least to the 02 position or it would indicate "No".

The "B" distractor is plausible since the first part is correct and the second if the applicant does not remember the confirm shutdown criteria of displaying "YES" if all rods are at least to 02 and thinks the OATC must depress "List Rods" to determine the remaining positions.

The "C" distractor is plausible if the applicant does not remember that with the "White" RPS Scram Group lights remaining ILLUMINATED, that the K14 relays will remain energized. The second part is correct.

The "D" distractor is plausible if the applicant does not remember that with the "White" RPS Scram Group lights remaining ILLUMINATED, that the K14 relays will remain energized. The second if the applicant does not remember the confirm shutdown criteria of displaying "YES" if all rods are at least to 02 and thinks the OATC must depress "List Rods" to determine remaining positions.

2011 Hatch 301 DRAFT

4. 203000A2.13 001 A Unit 1 Reactor startup is in progress with reactor pressure 400 psig.

At 10:00 a LOCA signal is received causing Reactor pressure to decrease 50 psig per minute.

IAW 34SO-E11-010-1, Residual Heat Removal, which ONE of the following states when the 1E11-F015A, RHR injection valve, will automatically start opening and how RHR A Loop injection can be prevented?

1E11-F015A will automatically start opening __________ .

At 10:04, WITHOUT overriding ANY interlocks, RHR A Loop injection can be prevented by __________ .

A. ONLY after reactor pressure is less than 370 psig; EITHER tripping RHR pumps OR closing 1E11-F017A, RHR injection valve B. ONLY after reactor pressure is less than 370 psig; tripping RHR pumps ONLY C. IMMEDIATELY; EITHER tripping RHR pumps OR closing 1E11-F017A, RHR injection valve D. IMMEDIATELY; tripping RHR pumps ONLY DRAFT 04/18/2011

2011 Hatch 301 DRAFT

==

Description:==

F015A/B automatically opens (F015 is normally closed) on receipt of a LOCA signal when reactor pressure decreases to < 449 psig. Although the RHR injection flowpath is aligned at 449 psig, flow to the RPV will not occur until RPV pressure drops below the RHR shutoff head of approximately 220 psig.

F017A/B auto opens if closed (F017A/B is normally open) on receipt of a LOCA signal if reactor pressure is < 449 psig. F017A/B is also interlocked open on a LOCA signal for 11 minutes AFTER reactor pressure has decreased to < 449 psig. The valve cannot be closed until the timer times out or the interlock is jumpered out as directed by the EOPs.

When reactor pressure decreases to less than 449 psig, F015A/B and F017A/B open (F017 is normally open). When RPV pressure decreases to 370 psig, Recirc pump discharge valves, B31-F031A/B, close and can not be reopened.

1E11-F048 A/B automatically opens on a LOCA signal and the valves are interlocked open for three minutes (cannot be closed with the control switch). The valve is interlocked open to ensure maximum injection rate immediately following a LOCA signal.

The "A" distractor is plausible if the applicant confuses the F017 & F015 opening pressure with the 1B31-F031A/B pressure permissive of 370 psig. After 5 minutes has elasped, reactor pressure will be below 370 psig. The second part is plausible if the applicant confuses the F048A/B opening timed interlock of 3 minutes with the F017A/B timed interlock.

The "B" distractor is plausible if the applicant confuses the F017 & F015 opening pressure with the 1B31-F031A/B pressure permissive of 370 psig. After 5 minutes has elasped, reactor pressure will be below 370 psig. The second part is correct.

The "C" distractor is plausible since the first part is correct and the second if the applicant confuses the F048A/B opening timed interlock of 3 minutes with the F017A/B timed interlock.

A. Incorrect - See description above.

B. Incorrect - See description above.

C. Incorrect - See description above.

D. Correct - See description above.

Description:==

This question tests whether the applicant understands the RHR system discharge valve arrangement and location. The applicant is being examined on the following valves:

o Air operated check valve (2E11-F050) o Inboard Discharge Valve (2E11-F015) o Outboard Discharge Valve (2E11-F017).

F050 is located INSIDE the DW, downstream of both F015 and F017.

F015 is located OUTSIDE the DW, between F050 and F017.

F017 is located OUTSIDE the DW, upstream of both F015 and F050.

With a flange leak on on F017, the water will be going into the Reactor Building/Secondary Containment due to the valves location.

When F015 is closed, water from the reactor is isolated from F017 due to the valve arrangement (described above).

The "A" distractor is plausible since the first part is correct and the second is plausible if the applicant does not remember the above valve location/arrangement in the RHR injection flowpath.

The "C" distractor is plausible if the applicant does not remember the above valve location/arrangement in the RHR injection flowpath and thinks any water leaking from the valve will be into Primary Containment. The second part is correct.

The "D" distractor is plausible if the applicant does not remember the above valve location/arrangement in the RHR injection flowpath and thinks any water leaking from the valve will be into Primary Containment. The second is plausible if the applicant does not remember the above valve location/arrangement in the RHR injection flowpath.

2011 Hatch 301 DRAFT

==

Description:==

This question tests the applicants knowledge of the correct method for shutting HPCI down while an initiation signal is present (i.e. in this case: high DW pressure).

A NORMAL shutdown (section 7.3.1) directs the applicant to:

o Reduce HPCI to approx. 2000 rpm o Press the HPCI Turbine Trip pushbutton o Verify the HPCI Aux Oil Pump starts (1500 rpm) o Close 2E41-F001 o The trip pushbutton is released after F001 is fully closed o The Aux Oil Pump remains running for 10 to 15 minutes after the F001 valve is closed.

When shutting down the HPCI system with an initiation signal present, attempting to close 2E41-F001 will simply result in F001 coming right back open due to the initiation logic providing an OPEN signal to the valve.

The steps for securing HPCI with an initiation signal present are contained in 34SO-E41-001-2, section 7.4.4, Preventing HPCI Injection To The RPV (Note: The applicant is directed to this section from 7.3.1, Control Room Shutdown when an Initiation signal is present).:

IF HPCI is operating, perform the following:

Depress AND hold the HPCI Turbine Trip pushbutton WHEN the HPCI turbine has stopped, place 2E41-C002-3, HPCI Aux Oil Pump, in PULL-TO-LOCK.

WHEN HPCI TURBINE BRG OIL PRESS LOW alarm is received, release the HPCI Turbine Trip push-button.

The "A" distractor is plausible if the applicant confuses this action with securring the Aux Oil pump which is securred when turbine speed reaches zero rpms.

The "B" distractor is plausible if the applicant confuses this action with securring HPCI normally. If this was a normal shutdown, this distractor would be correct.

The "D" distractor is plausible if the applicant confuses this action with securring the Aux Oil pump when HPCI is not in operation and the operator desires to prevent it from starting.

A. Incorrect - See description above.

B. Incorrect - See description above.

C. Correct - See description above.

D. Incorrect - See description above.

B. The pump trips due to low suction pressure.

C. The motor winding temperatures are steadily increasing.

DRAFT 04/18/2011

2011 Hatch 301 DRAFT

==

Description:==

This question evaluates the applicants knowledge of how CS pump cavitation will affect plant indications.

Erratic flow is one consequence of cavitation. The opening (700 gpm) and closing (950 gpm) setpoints of E21-F031A/B is sufficiently close to the 1000 gpm being pumped through the system that it is possible, with sufficient cavitation occurring, for flow to swing 300+ gpm which will to cause F031 to open and close.

When cavitation occurs, motor amps will fluctuate, but on average, will actually decrease due to less water being pumped.

Motor winding temperature is an equilibrium condition based on heat removal systems (diagonal ventilation system used to cool the motor) and heat producing components (motot bearing friction, windage etc. and, principally, I2R heating of the windings). Assuming the heat removal system remains unchanged, overall heating of the windings due to I2R will actually decrease, over time, due to the reduced volume being pumped caused by cavitation.

Unlike some other ECCS systems, the Core Spray pumps do not have a low suction pressure trip.

The "A" distractor is plausible if the applicant confuses which way motor amps will change when a pump is experiencing cavitation.

The "B" distractor is plausible if the applicant remembers that some ECCS pumps have a low suction pressure trip and confuses this with Core Spray.

The "C" distractor is plausible if the applicant confuses which way motor winding temps will change when a pump is experiencing cavitation.

A. Incorrect - See description above.

B. Incorrect - See description above.

C. Incorrect - See description above.

D. Correct - See description above.

Description:==

The malfunction of the Core Spray (CS) injection valve will de-energize 1R24-S011, Reactor Bldg. Motor Control Center (MCC), which is the power supply to 1E21-F015A, Core Spray Injection Valve. With this MCC de-energized, 1C41-C001A, SBLC pump will be de-energized, leaving only one SBLC pump available for injection. 1C41-C001B, SBLC pump, is powered by 1R24-S012, Reactor Bldg. MCC, which is also the power supply to 1E21-F015B, CS Injection valve.

The "B" distractor is plausible since the first part is correct and the second part if the applicant does not realize that the de-energized MCC is the same power supply of the 1A SBLC pump.

Also if the applicant thinks that the CS injection valves are arranged similar to the RHR inboard

& outboard injection valves which have two different power supplies for the injection valves in the same loop. One comes from S011/S012 the other comes from 1R24-S018A/B, which would lead the applicant to think S011 was not de-energized.

The "C" distractor is plausible if the applicant does not remember the power supply to 1E21-F015A and confuses this with the power supply to 1E21-F015B. The second part is correct.

The "D" distractor is plausible if the applicant does not remember the power supply to 1E21-F015A and confuses this with the power supply to 1E21-F015B.

Also if the applicant thinks that the CS injection valves are arranged similar to the RHR inboard & outboard injection valves which have two different power supplies for the injection valves in the same loop. One comes from S011/S012 the other comes from 1R24-S018A/B, which would lead the applicant to think S011 was not de-energized.

Description:==

The RPS MG sets supply power to their respective buses. The alternate power supply comes from Essential A or B (normal position B). After the "1B" RPS MG Set trips, half of the scram relays (B channel) are de-energized. When the Power Source Select switch is placed to the "Alt A" position, the scram relays in the A channel of RPS will de-energize, resulting in ALL scram relays being de-energized. Five (5) seconds later, the A channel of RPS will be energized from the Alternate power supply coming from either Essential Cabinet A or B.

The "A" distractor is plausible since the first part is correct and the second if the applicant thinks that since the A RPS Channel Scram Relays are de-energized that the RPS A Bus is also de-energized.

The "C" distractor is plausible if the applicant does not remember the relay interlock when transferring a RPS Bus to alternate supply and thinks that only the "B" RPS Scram Relays are de-energized. The second part is correct.

The "D" distractor is plausible if the applicant does not remember the relay interlock when transferring a RPS Bus to alternate supply and thinks that only the "B" RPS Scram Relays are de-energized. The second par if the applicant thinks that since the A RPS Channel Scram Relays are de-energized that the RPS A Bus is also de-energized.

Description:==

A high voltage supply continuously decreasing to 0 VDC will cause IRM "A" indication to decrease. When the high voltage supply reaches the low setpoint, an INOP trip condition will exist for the "A" IRM. This will result in a half scram and rod block.

The "B" distractor is plausible if the applicant remembers that the P603 indication (recorder) will remain as is if the P603 recorder loses its power supply. The second part is plausible if the applicant remembers that a rod block from IRM downscale will not occur if the range switch is positioned to 1 and confuses this with IRM Inop and also thinks that this will bypass the half scram.

The "C" distractor is plausible if the applicant remembers that the P603 indication (recorder) will remain as is if the P603 recorder loses its power supply. The second part is correct.

==

Description:==

Each 2/4 Logic module supplies its safety trip signals to a separate section of the RPS.

Therefore, each 2/4 Logic Module can, by itself, generate a half-scram. Two of the modules can produce a half-scram in RPS trip channel A and are therefore redundant. Similarly, the other two modules are redundant in their ability to produce a half-scram in RPS trip channel B.

The 2/4 Logic Modules are designed to default to a trip condition. Loss of APRM/OPRM channel trip status signal causes the logic to assume a trip condition for those input signals. The 2/4 logic is powered by the same RPS power by which the output circuit is powered, so that loss of RPS power causes the 2/4 Logic Module to generate a trip even though that trip signal is supplied to a deenergized RPS trip circuit. Both effects, individually or together, generate a half-scram.

The "B" distractor is plausible since the first part is correct and the second if the applicant confuses the output of the 2/4 voter going to only one side of RPS, therefore only one RPS Bus will generate a scram signal. This would be the case if the question was for the A & C 2/4 voters instead of B & C 24 voters.

The "C" distractor is plausible if the applicant confuses the output of the 2/4 voter going to only one side of RPS, therefore only one RPS Bus will generate a scram signal. This would be the case if the question was for the B & D 2/4 voters instead of B & C 24 voters. The second part is correct.

The "D" distractor is plausible if the applicant confuses the output of the 2/4 voters with the output of APRMs and remembers that a half-scram cannot be generated from APRMs since the new PRNMs were installed. In this case the applicant will not think that a half scram will be generated in either RPS Bus.

A. Correct - See description above.

B. Incorrect - See description above.

Description:==

This question tests the applicants knowledge of the RCIC suction valve interlock logic.

In order for the CST suction path valve (2E51-F010) to auto CLOSE, the logic requires that BOTH the Torus suction valves (2E51-F029 & F031) be FULL OPEN.

Operators often confuse this with Pressure Control logic controlling 2E51-F022, Return to CST/Test Valve. ONE Torus suction valve fully OPEN will cause F022 to automatically close.

The "A" distractor is plausible if the applicant confuses the first Torus Suction valve red light illuminating as when the signal to open for the 2E51-F010 is first received.

The "B" distractor is plausible if the applicant remembers the Torus Suction valve has to be full open to demand a close signal for 2E51-F010. It would take both Torus Suction valves full open to cause a signal for 2E51-F010. This distractor would be correct if the discussion was for 2E51-F022.

The "D" distractor is plausible if the applicant confuses the red light illuminated for both Torus Suction valves with the requirement to have both valve full open.

This question tests the applicants knowledge of the normal power supply to ADS logic.

The control logic is powered from the station service batteries through 125VDC bus 2A (2R25-S001) and 2B (2R25-S002). The "A" and "B" logic is normally powered from the 125VDC 2A bus.

Description:==

This question tests the applicants knowledge of the Torus level at which the HPCI exhaust pipe becomes uncovered and the resultant impact on the Torus Air Temperature, in addition to where the temperature can be read by the operator.

Indication for individual RTDs can be found on the same multipoint recorder as the air temperature RTDs on panels 2H11-P650 and P657.

On Unit 2 the HPCI exhaust in uncovered when Torus level decreases to below 110 inches.

In the question, the applicant is initially given a Torus level is 140 inches which subsequently decreases to 105 inches. At this point HPCI will be discharging steam directly to the Torus.

This results in temperature and pressure increasing rapidly.

The "A" distractor is plausible if the applicant does not remember the Torus level at which the HPCI exhaust line is uncovered and the Torus air temp rate will be approximately the same. The second part is correct.

The "B" distractor is plausible if the applicant does not remember the Torus level at which the HPCI exhaust line is uncovered and the Torus air temp rate will be approximately the same. The second part is plausible if the applicant remembers this panel contains indication of Torus parameters as well, just not Torus Air temperature.

The "C" distractor is plausible since the first part is correct and the second part is plausible if the applicant remembers this panel contains indication of Torus parameters as well, just not Torus Air temperature.

Description:==

This question tests the applicants knowledge of AB procedure entry requirements due to high Torus temp and whether SPDS displays Torus bulk average temperature (vs single point temp indications).

Torus bulk temperature is displayed on the SPDS Primary Display.

SPDS also has a screen (Torus Water Temperature Diagnostic) that displays single point Torus temp indications.

Torus Water Temp High Annunciator (P604-020) annunciates at 95°F. This annunciator is listed as and entry condition for 34AB-T23-003-2.

The "A" distractor is plausible since the first part is correct. The second is plausible since this is the temperature for entry into the PC EOP flowchart and the applicant confuses this with the Abnormal entry temperature.

The "B" distractor is plausible if the applicant does not remember if the "Primary Display" indicates a bulk average temperature and thinks that the Torus temperature "Diagnostic" screen is the only place where Torus bulk average temperature is indicated. The second is plausible since this is the temperature for entry into the PC EOP flowchart and the applicant confuses this with the Abnormal entry temperature.

The "D" distractor is plausible if the applicant does not remember if the "Primary Display" indicates a bulk average temperature and thinks that the Torus temperature "Diagnostic" screen is the only place where Torus bulk average temperature is indicated. The second part is correct.

A. Incorrect - See description above.

Description:==

This question tests the applicants knowledge of how the Main Turbine trip logic inputs, directly, to the RPS logic (i.e. Turbine Stop Valves (TSVs) and Trubine Control Valves (TCVs).

TSVs input to the RPS logic such that the correct combination of 2 TSVs going closed may cause a 1/2 scram or no RPS response at all (based on direct input to RPS logic).

Any 3 TSVs will result in a full reactor scram. This logic is similar to MSIV logic (Means and Extremes)

Example: TSV #1 and #2 - Half Scram TSV #1 and #3 - Half Scram TSV #1 and #4 - No RPS response TSV # 2 and #3 - No RPS response TSV #1, 2 and #3 - Full Scram TSV #2, 3 and #4 - Full Scram etc.

Each TCV inputs to a separate RPS logic channel (A1 or A2 or B1 or B2) and as such, any one valve sensed going closed (based on EHC oil pressure) will actuate a 1/2 scram.

The "A" distractor is plausible if the applicant confuses the TCV closing logic with the TSV closing logic and thinks any two TCVs will cause a half scram. The second part is correct.

The "B" distractor is plausible if the applicant confuses the TCV closing logic with the TSV closing logic and thinks any two TCVs will cause a half scram. The second part is plausible if the applicant thinks that one TSV closing will input one RPS Division Logic and the second TSV closing inputs into the other RPS D ivision Logic generating a full scram.

The "D" distractor is plausible since the first part is correct. The second part is plausible if the applicant thinks that one TSV closing will input one RPS Division Logic and the second TSV closing inputs into the other RPS D ivision Logic generating a full scram.

A. Incorrect - See description above.

B. Incorrect - See description above.

C. Correct - See description above.

Description:==

IAW 34SO-N21-007-2, Condensate And Feedwater System, Condensate flow through the intercondensers is controlled by the positioning of the intercondensers bypass valve, 2N21-F007. By opening the valve (lowering dp across valve) less flow is directed through the intercondenser. By closing the valve (increasing the dp across the valve) more Condensate water is directed through the intercondenser flowpath direction thus giving more cooling for higher power conditions. With increased flow to the SJAE via increased dP, the system pressure downstream will be reduced due to the increased dP in the system. This will lower the system pressure at the inlets to the demins.

The "A" distractor is plausible since the first part is correct and the second part if the applicant confuses dP increasing with increasing the inlet pressures to the Cond. Demins, which is actually decreasing. Also if the applicant confuses the operation of this valve with the SULCV Bypass which allows more flow to the reactor when opened.

The "C" distractor is plausible if the applicant thinks opening the valve will allow more flow through the SJAE since opening most valves increases the flow through the system. The second part if the applicant confuses dP increasing with increasing the inlet pressures to the Cond.

Demins, which is actually decreasing. Also if the applicant confuses the operation of this valve with the SULCV Bypass which allows more flow to the reactor when opened.

The "D" distractor is plausible if the applicant thinks opening the valve will allow more flow through the SJAE since opening most valves increases the flow through the system. The second part is correct.

Failure of the Master Controller / Loss of Signal from Master Controller, C32-R600

1. If the "RFP A" M/A station is in Automatic, it will maintain RWL in the Single Element utilizing 37 inches as the default setpoint (PF light flashing).

The "RFP A" M/A station setpoint may be adjusted with the set up and down keys.

2. The "B" M/A Station will default to Manual Control (it cannot change speed automatically as RWL changes).

3. RFPT A M/A Controller will control RWL in the Automatic mode.

The "A" distractor is plausible since this would be correct if the question was asking the response to a loss of Instrument Bus A, which will cause RFP A M/A Station to lose power and control to transfer to the Speed Setter.

The "B" distractor is plausible since this would be correct if the question was asking the response to a loss of Vital AC bus, which will cause RFP B M/A Station to lose power and control to transfer to the Speed Setter.

The "D" distractor is plausible since this would be correct if RFP A M/A Staion was in "Manual". RFP B M/A Station would then be automatically controlling reactor water level.

A. DECREASE DECREASE B. DECREASE INCREASE C. INCREASE DECREASE D. INCREASE INCREASE DRAFT 04/18/2011

2011 Hatch 301 DRAFT

==

Description:==

This question tests the applicants understanding of the INITIAL response to a reference leg break associated with R606A (R606C uses this same reference leg), how it affects the RFPT speed and how the instruments that come off a different reference leg will respond.

A leak in the reference leg causes 2C32-R606A & C to drift UP. Since one of these instruments is the Median signal (the level indication that is in the middle as determined by the SCMS module (C32-K648)), the RWLC sistem senses that RWL is high (above the setpoint of the Master RFP controller). This causes an initial response of a RFP speed reduction, which causes actual RWL to decrease.

Since the "R606B" is working normally, it responds to actual level conditions and its indication begins to decrease.

The "B" distractor is plausible since the first part is correct and the second if the applicant confuses which instruments will be affected and which way they will fail. If so the applicant could think RWL is going down and think RFPT speed will be increasing.

The "C" distractor is plausible if the applicant remembers two R606s will be affected and thinks R606B is the second instrument. If so, R606B would then be increasing along with R606A. The second part is correct.

The "D" distractor is plausible if the applicant remembers two R606s will be affected and thinks R606B is the second instrument. If so, R606B would then be increasing along with R606A. The second is plausible if the applicant confuses which instruments will be affected and which way they will fail. If so the applicant could think RWL is going down and think RFPT speed will be increasing.

A. Correct - See description above.

B. Incorrect - See description above.

Description:==

Upon a loss of the Normal Power source to 4160 VAC busses A, B, C and D, the normal supply breakers will automatically open and the alternate supply breakers will automatically close when both generators output PCBs are opened. This is known as a FAST TRANSFER. This operation normally occurs following a manual or auto turbine trip. It ensures that all loads remain energized. There are several conditions in the electrical distribution system which will lockout (prevent) a fast transfer. Those conditions are as follows:

If the fast transfer does not occur within 0.2 seconds, the automatic fast transfer is locked out, requiring a manual transfer to re-energize the 4160 VAC Station Service Busses 2A, B, C, & D.

If any of the 4160 VAC Emergency Busses are tied to the 2C SAT (Alternate), a fast transfer of house loads is prohibited and the SAT supply breakers to 4160 2A and B receive a trip signal.

When the Main Turbine trips, the Fast transfer will not occur, therefore leaving all Station Service buses de-energized. Manual transfer to SAT 2D is allowed for the 4160 VAC Busses 2C and 2D only, and is required if the generator is no longer available.

The "B" distractor is plausible since the first part is correct and the second if the applicant confuses which buses will lose power, their power supplies and which 4160 V Buses can be re-energized.

The "C" distractor is plausible if the applicant thinks that only 2 buses did not Fast transfer and that Station Service Bus 2C & 2D will be manually re-energized from SAT 2D. The second part is correct.

The "D" distractor is plausible if the applicant thinks that only 2 buses did not Fast transfer and that Station Service Bus 2C & 2D will be manually re-energized from SAT 2D. The second if the applicant confuses which buses will lose power, their power supplies and which 4160 V Buses can be re-energized.

Description:==

The RPS MG set trips on loss of power on loss of power and in order to restart the RPS MG set, an operator must manually start it locally after power has been restored to the 600 VAC bus.

Restoration actions are directed from 34AB-R23-001-1 and 34AB-C71-002-1.

In addition, the associated RPS protection circuit breakers trip on loss of power:

Each MG set is provided with a voltage regulator, complete with an under-voltage relay (UVR),

under-frequency relay (UFR), over-voltage relay (OVR), and a spike suppression filter as protective devices. In the event of a low voltage condition for an extended period of time, the scram solenoids can chatter and potentially lose their pneumatic control capability, resulting in a loss of primary scram action. To provide protection against degraded electrical conditions on the RPS busses, the output of each RPS MG set is run through two series equipment protection panels. Each equipment protection panel contains an isolation breaker, which will trip on overvoltage (129 VAC), undervoltage (111.5 VAC), and underfrequency (57.2 Hz).

The "A" distractor is plausible since the first part is correct. The second is plausible because there are some circuit breakers that remain closed when their power supply is lost and the applicant confuses this with RPS Circuit breakers.

The "B" distractor is plausible since there are power supplies that automatically power up when power is restored to the respective 600 V 1C or 1D. The applicant can confuse this with RPS and think it comes back automatically as well. The second is plausible because there are some circuit breakers that remain closed when their power supply is lost and the applicant confuses this with RPS Circuit breakers.

32. 264000K6.08 001 Unit 2 is performing an Emergency Diesel Generator (EDG) surveillance.

The "2A" EDG is running with its mode switch in TEST, but NOT tied to its bus.

At this time, the normal breaker to 4160 VAC bus "2E" trips open.

Which ONE of the following is the status of 4160V bus "2E" and EDG "2A"?

A. EDG "2A" remains in TEST and 4160V bus "2E" swaps to its alternate power supply.

B. EDG "2A" Test Circuit de-energizes and EDG "2A" ties to 4160V bus "2E".

C. EDG "2A" Test Circuit de-energizes and 4160V bus "2E" swaps to its alternate power supply.

D. EDG "2A" remains in TEST and 4160V bus "2E" is de-energized.

Description:

A LOCA or LOSP signal will deenergize the diesel generator Test relays regardless of the position of the diesel generator mode switch. If Startup Transformer 2C (alternate supply) is deenergized, the Test relays will deenergize unless the DIESEL TEST SAT 2C OUT OF SVC INTERLOCK switch is in the TEST position. Since the Test relays remain energized the Alternate supply will NOT close in when the Normal supply breaker trips open, therefore leaving the bus de-energized.

The "A" distractor is plausible if the applicant does not remember that the test relays are still energized and the transfer to alternate will occur normally.

The "B" distractor is plausible if the applicant confuses the test relay logic and thinks it de-energizes allowing the EDG 2A to tie to 4160 V bus 2E.

The "C" distractor is plausible if the applicant confuses the test relay logic and thinks it de-energizes allowing the transfer to alternate to occur normally.

Which ONE of the following is the Off Gas component that receives a signal to close?

A. 2N62-F057, Offgas Stack Inlet Valve B. 2N62-F042, Offgas Inlet to Adsorber Valve C. 2N62-F085, Offgas Holdup Line Drain Valve D. 2N62-F043, Offgas Adsorbers Bypass Valve.

Description:

With the Off Gas mode switch in "Auto", the F042 is closed and F043 is open. This lineup is used during startup when there is high flow of non-radioactive gas. However, it does not allow automatic operation in the event of high radiation in Off-Gas. If a high radiation condition occurs as sensed by the Post treatment Monitors, the F042 opens and the F043 closes. This will direct the Off Gas flow through the Adsorbers to start filtering the process flow.

The "A" distractor is plausible since this valve isolates on a radiation condition generated by the Post treatment monitors. This condition is inop, downscale or a hi-hi-hi, in any combination in both channels. A Hi condition just swaps the inlet & bypass to the adsorbers.

The "B" distractor is plausible since this valve changes position on a Hi radiation signal just not in the closed direction. The applicant must realize the lineup in Auto and which valves change position and the direction of travel.

The "C" distractor is plausible since this valve isolates on a radiation condition generated by the Post treatment monitors. This condition is inop, downscale or a hi-hi-hi, in any combination in both channels. A Hi condition just swaps the inlet & bypass to the adsorbers.

Description:==

During single loop operation, when the speed of the running pump decreases below approximately 35% speed, positive flow through the idle pump loop due to natural circulation overcomes the negative flow due to reverse flow. The total core flow summing circuitry will continue to subtract this positive idle loop flow from the running loop flow and give a misleading LOW core flow indication. Total Core Flow can be calculated by adding the JET PUMP LOOP A AND the JET PUMP LOOP B flows.

The "B" distractor is plausible since the first part is correct and the second if the applicant does not remember to add the idle loop flow to the other loop, not to the recorder.

The "C" distractor is plausible if the applicant does not remember the correct way to determine core flow. The flow recorder value is providing a misleading LOW core flow indication because the 2A jet pump loop flow is positive (ie., not reverse).

The "D" distractor is plausible since below 35% pump speed, this flow is positive due to natural circulation. Plausible if applicant is unaware that an ASD relay causes the subtraction to occur automatically.

Description:==

The DC distribution system is a two-wire ungrounded battery/charger system equipped with ground-detection/alarm circuitry annunciating in the control room. Ground detectors are incorporated in the DC system so that if a single ground does occur, personnel are aware of the ground and can take immediate steps to investigate and clear the ground fault from the system.

If a ground occurs on the DC Distribution System, it must be investigated immediately. Failure to promptly eliminate a single ground could mask subsequent additional grounds and cause a possible personnel/equipment safety hazard if a second ground were to occur. A single ground in a control system will not result in component actuation or substantial heat generation (i.e.

cause a fire) due to not enough difference in potential to cause sufficient current flow through a device.

The "A" distractor is plausible since 22,000 is above the 19,000 procedure limit. This is a common misconception as to which side of 19,000 requires isolation of system loads. The second part is correct.

The "C" distractor is plausible since 22,000 is above the 19,000 procedure limit. This is a common misconception as to which side of 19,000 requires isolation of system loads. The second part is plausible since multiple grounds cause spurious equipment actuation, but single grounds normally do not. Also plausible since a single ground could result in spurious equipment operation with use of a low resistance ground detection system.

The "D" distractor is plausible since the first part is correct and the second part is plausible since multiple grounds cause spurious equipment actuation, but single grounds normally do not. Also plausible since a single ground could result in spurious equipment operation with use of a low resistance ground detection system.

==

Description:==

31RS-OPS-001-2, Shutdown From Outside Control Room, requires tripping the Main Turbine after the reactor has been shutdown. A local turbine trip is accomplished using the Emergency Tripping Device at the main turbine front standard area, which consists of two pushbuttons.

Both main turbine trip pushbuttons must be simultaneously pressed to trip the main turbine.

IAW 34SO-N30-001-2, Main Turbine Operation, Section 7.3.1, Note states "IF the turning gear is on alternate power supply, it will NOT automatically start and engage. It must be started manually at panel 2H21-P203." IF the Control Room is uninhabitable, the TGOP start must be confirmed by local observation of the pump. The TGOP will still auto start as the Turbine coasts down. The TGM and the TGOP (turning gear oil pump) are supplied by the same power supply at all times.

The "A" distractor is plausible if the applicant confuses how to trip the main turbine trip with tripping other turbines such as RFPTs, RCIC & HPCI, which only require one pushbutton or switch to trip them. Also a recent change to the front standard, changed the trip function from one pull handle to two pushbuttons. The second part is correct.

The "B" distractor is plausible if the applicant confuses how to trip the main turbine trip with tripping other turbines such as RFPTs, RCIC & HPCI, which only require one pushbutton or switch to trip them. Also a recent change to the front standard, changed the trip function from one pull handle to two pushbuttons. The second part if the applicant remembers that the TGM will not auto start or engage under certain conditions and confuses this with TGOP operation.

The "C" distractor is plausible since the first pat is correct and the second part if the applicant remembers that the TGM will not auto start or engage under certain conditions and confuses this with TGOP operation.

Description:==

2E11-F048 A/B automatically opens on a LOCA signal and the valves are interlocked open for three minutes (cannot be closed with the control switch).

IAW 31EO-EOP-010-2, RC EOP Flowchart, the RHR LPCI Shutoff head is 220 psig while Core Spray Shutoff head is 383 psig.

The "A" distractor is plausible since the first part is correct and the second if the applicant does not remember the RHR LPCI Shutoff head or confuses it with the Core Spray Shutoff head of 383 psig. In this case the applicant would choose 250 psig which is below 383 psig.

The "B" distractor is plausible if the applicant does not remember the interlock associated with a LOCA signal.

600V Emergency Bus 2C supplies 2 of the 3 RBCCW pumps, ie., 2A & 2C pumps. Normally the 2A & 2B RBCCW pumps will be running. There will be no standby pump (2C) to start resulting in only the 2B pump running therefore, RBCCW flow inside the Drywell will be lower than the flow before 2C 600 VAC Switchgear tripped.

The "A" distractor is plausible since the first part is correct. The second is plausible if the applicant confuses the normal lineup and pump power supplies and thinks two pumps will still be operating. Other systems, such as Station Service Air Compressors (SSACs), have 1 SSAC powered from 600 2C, 1 powered from 600 2D and the other from a Station Service Bus. The applicant can confuse this with RBCCW power supplies and think 2 RBCCW pumps are still in service, since only 600 2C is lost.

The "B" distractor is plausible if the applicant does not remember the auto start requirements for the standby RBCCW pump and thinks system pressure did not drop to the auto start setpoint of 90 psig. The second is plausible if the applicant confuses the normal lineup and pump power supplies and thinks two pumps will still be operating.

This will continue to provide motive force for the Outboard MSIVs to remain opern.

The "B" distractor is plausible since the first part is correct and the second if the applicant does not remember the opening setpoint for the 2P52-F565.

The "C" distractor is plausible since this valve senses upstream pressure and would cycle open and close as the header pressure upstream of this valve changed above and below 50 psig. When this valve closes upstream header pressure would increase causing this valve to re-open and the cycle would continue. The second part is correct.

The "D" distractor is plausible since this valve senses upstream pressure and would cycle open and close as the header pressure upstream of this valve changed above and below 50 psig. When this valve closes upstream header pressure would increase causing this valve to re-open and the cycle would continue.

Attachment 2 of the Scram Procedure requires the Group Isolation Switches to be placed in the Gr. 2/5 position to open the F008/F009, RHR SDC valves.

The "A" distractor is plausible if the applicant does not remember the requirement for being in the EOPs and only remembers the Mode 4 or 5 condition (currrent Mode is 3). Loading considerations for the 1B EDG will be zero since there are no conditions indicating the 1B EDG is running loaded. The second part is plausible if the applicant does not remember the Group 6 isolation signal is reset by using the Gr. 2/5 switches nor remembers that a loss of 600 2D will cause RHR SDC valves to isolate.

The "B" distractor is plausible if the applicant does not remember the requirement for being in the EOPs and only remembers the Mode 4 or 5 condition (currrent Mode is 3). Loading considerations for the 1B EDG will be zero since there are no conditions indicating the 1B EDG is running loaded. The second part is correct.

==

Description:==

On a non LOCA scram, the accumulators discharge, causing CRD flow to be diverted to the charging water header. The flow control, valve F002A/B, senses maximum flow and closes.

When the Scram is reset, the accumulators will recharge, the Flow Control Valve will open, and the system returns to normal conditions. The System response for a Scram with a LOCA signal is similar except the CRD pumps will trip and the flow controller will sense no flow, causing the Flow Control Valve (F002) to open fully.

The "B" distractor is plausible if the applicant thinks that the CRD system will be sensing maximum flow and that a minimum amount of cooling water flow will be provided until the NPO resets the scram. Once reset, system flow & FCV will return to a normal non scram position/value.

The "C" distractor is plausible if the applicant does not recognize the CRD pumps have tripped and remembers how the system responds on a non LOCA scram condition.

The "D" distractor is plausible if the applicant confuses thermal stratification when both Recirc pumps have tripped, with a LOCA scram. Allowing the scram to be remain in a tripped condition, will allow excessive amounts of water to be injected through the CRD system and possibly causing thermal stratification.

A. Correct - See description above.

B. Incorrect - See description above.

Description:==

IAW TS B 3.3.4.2, Excessively high RPV pressure may rupture the RCPB. An increase in the RPV pressure during reactor operation compresses the steam voids and results in a positive reactivity insertion. This increases neutron flux and THERMAL POWER, which could potentially result in fuel failure and APPLICABILITY overpressurization. The Reactor Steam Dome Pressure - High Function initiates an RPT for transients that result in a pressure increase, counteracting the pressure increase by rapidly reducing core power generation.

IAW 34SO-B31-001-1/2, Reactor Recirculation System, Limitation 5.2.2.6, states 1170 psig is the reactor pressure for the ATWS trip. 1150 psig is the value where all SRVs will be open mechanically.

Description:==

The 1E11-F028A & F024A valves are interlocked closed for the duration of the LOCA signal, in this case -101". However, during a LOCA condition, it may be necessary to spray the containment or place Torus cooling in service. Therefore, the valves are interlocked closed for the duration of the LOCA signal UNLESS:

With a LOCA signal present the containment spray valve control switch (pistol grip) is positioned to MANUAL or:

With a LOCA signal present and water level <-193, the Containment Spray Valve Manual Override keylock permissive switch (2/3 core height) is placed to MANUAL OVERRIDE and then the containment spray valve control switch (pistol grip) is placed to MANUAL.

With compensated RWL at 180" the un-compensated RWL will be below the 2/3 Core Height permissive of -193". This will require both switches above to be placed in the Manual & Manual Override positions in order to open both Torus Cooling Valves.

The "B" distractor is plausible since the first part is correct and the second if the applicant does not remember that the 2/3 permissive comes off of uncompensated RWL instruments and therefore will be below the -193" level. The applicant will think RWL is above the 2/3 permissive.

The "C" distractor is plausible if the applicant does not remember that this switch is also applicable for RWL low as well as DW pressure being high. With DW pressure only 1.5 psig the applicant may think it is not required to be manipulated. The second if the applicant does not remember that the 2/3 permissive comes off of uncompensated RWL instruments and therefore will be below the -193" level. The applicant will think RWL is above the 2/3 permissive.

The "D" distractor is plausible if the applicant does not remember that this switch is also applicable for RWL low as well as DW pressure being high. With DW pressure only 1.5 psig the applicant may think it is not required to be manipulated. The second part is correct.

Once this level is reached, the operator must use alternative methods to determine primary containment water level.

The "A" distractor is plausible if the applicant does not remember or confuses this level, since 285 inches is the Torus level where the Torus Spray header is submerged. The second part is correct.

The "B" distractor is plausible if the applicant does not remember or confuses this level, since 285 inches is the Torus level where the Torus Spray header is submerged. The second part is plausible since these instruments measure dP between Drywell and Torus and the applicant thinking they are the ones required to be used.

Description:==

The Control Room Ventilation System will automatically switch to the Pressurization Mode on any of the following signals:

LOCA signal from Unit 1 or Unit 2 RF Area High Radiation (ARM) from Unit 1 or Unit 2 (15 mr/hr)

Main Steam Line High Flow from Unit 1 or Unit 2 Main Control Room Air Intake High Radiation During Pressurization Mode, outside air (via F015 & F016) mixes with recirculation air and is treated by a filter train. The filter train discharges to the air handling units, which discharge into the Control Room. The exhaust fans are off and their suction dampers are closed. The only air flow out of the Control Rooms is through leakage.

The Isolation Mode has no makeup or discharge air flow. Part of the recirculation air flow is directed through the filter trains. When in this mode, the roll filter bypass (F015), outside air intake damper (F016) and both filter train inlet damper (F013A and F013B) must be closed by the operator.

The "A" distractor is plausible if the applicant thinks that since radiation levels are high, that isolating the Control Room, from the outside environment, will provide the necessary protection to personnel. The second part is plausible if the applicant remembers that the lineup for isolation mode requires the F015 valve to be in the closed position.

The "B" distractor is plausible if the applicant thinks that since radiation levels are high, that isolating the Control Room, from the outside environment, will provide the necessary protection to personnel. The second part is correct.

The "D" distractor is plausible since the first part is correct and the second part is plausible if the applicant remembers that the lineup for isolation mode requires the F015 valve to be in the closed position and confuses this with the pressurization mode position.

60. 295037EK1.01 001 During an ATWS, in order to avoid exceeding the Heat Capacity Temperature Limit (HCTL) graph, the SRO has ordered reactor pressure to be lowered to 700 psig using SRVs.

Which ONE of the following describes the reactor power response IMMEDIATELY following the opening of the SRVs and why?

A. Reactor power will rise due to the lowering of the reactor coolant temperature adding positive reactivity.

B. Reactor power will rise due to the water level inside the core rising causing more moderation of neutrons.

C. Reactor power will drop due to the voiding of the water in the core as it flashes to steam.

D. Reactor power will drop due to the moderator temperature rising caused by low flow through the core.

DRAFT 04/18/2011

2011 Hatch 301 DRAFT

==

Description:==

The pressure drop that occurs as SRVs are opened will result in an increase in void fraction in the core as saturated moderator flashes to steam. The increase presence of voids in the core will result in a decrease in power due to a drop in thermal neutrons. Moderator temperature will decrease to saturation temperature for the lower pressure value, but the void coefficient effect is the primary factor.

The "A" distractor is plausible if the applicant remembers lowering pressure will eventually cause coolant temperature to reach a lower saturation temperature and then cause positive reactivity to be added from the lower coolant temperature.

The "B" distractor is plausible if the applicant confuses indicated water level rising when an SRV is opened. Actual watel level in the core is being replaced by voids.

The "D" distractor is plausible if the applicant confuses reactor pressure reducing causing less NPSH delivered to the Recirc pumps, therefore resulting in a slightly less recirc/core flow through the core. With less flow through the core, moderator temperature will increase causing reactor power to decrease.

If the surge tank level again decreases to the demin makeup valve opening setpoint during that 13 hour1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> period, the following occurs:

1) The counter decreases to 0000.

2) The timer stops timing.

3) An annunciator sounds in the Main Control Room indicating excess leakage is occurring in the RBCCW System.

The RBCCW Surge Tank Timer is located on the 203' elevation of the Unit 2 Reactor Building on Panel 2H21-P350..

The "A" disctractor is plausible due to a misconception as to whether the counter counts up or counts down to indicate leakage. If it counts up, the counter will read "2" and if it counts down the counter will read "0". The second part is correct.

The "B" distractor is plausible due to a misconception as to whether the counter counts up or counts down to indicate leakage. If it counts up, the counter will read "2" and if it counts down the counter will read "0". The second part is plausible if the applicant thinks that, since the 2H11-P650 panel is the location of various other RBCCW controls/indications, that the timer will be reset from this panel.

The "C" distractor is plausible since the first part is correct and the second part if the applicant thinks that, since the 2H11-P650 panel is the location of various other RBCCW controls/indications, that the timer will be reset from this panel.

With alarm 651-114 alarming, a Simultaneous trip of the Main Transformer will occur.

Simultaneous type of tripping is used when immediate disconnection of the Generator is required. On a Main Transformer Sudden Pressure (Generator fault conditions), the main turbine will trip (reactor scrams since power > 27.6%), the EX2100 Static Exciter will trip and the Main Generator Output breakers will open simultaneously. When both Main Generator Output breakers open, the Station Service transfer logic will transfer supply to the Startup Transformers.

To ensure proper operation of the Main Generator with the different types of loading, the Generator capabilities curve is used. The curve is based on Hydrogen pressure, kilowatts, and megavars. Using the value for machine gas pressure, the generator pressure operating line should be the next lower pressure line. With Hydrogen pressure, GMWe, & MVARs at their present value, the generator is operating at a point that is outside the limits of the Generator Capability curve (Att. 1).

The "A" distractor is plausible since the first part is correct and the second if the applicant uses the wrong Hydrogen pressure line, 60 psig vs. 52 psig line.

The "C" distractor is plausible if the applicant remembers the "both Units in Cold, Refuel or De-fueled" value of 225 kV and compares to 231 kV. The second if the applicant uses the wrong Hydrogen pressure line, 60 psig vs. 52 psig line.

Description:==

34SV-E11-002-1, RHR Valve Operability, step 4.3.5 states: Full-stroke time is that time interval from initiation of the actuating signal to the end of the actuation cycle. Valves will be timed from WHEN the switch is positioned UNTIL either the green light EXTINGUISHES (open) OR the red light EXTINGUISHES (close). Step 7.7.2.2 states: Valves with OPERATING times that do NOT meet the CALCULATED ALLOWABLE time will be immediately retested OR declared inoperable. They can not be immediately declared OPERABLE.

The "A" distractor is plausible since the first part is correct. The second is plausible if the applicant thinks that since the valve meet the Maximum Time Limit, it can be immediately declared operable. The valve must be immediately re-tested.

The "B" distractor is plausible if the applicant thinks timing occurs when the red light first illuminates and does not know the procedure requirement. The second is plausible if the applicant thinks that since the valve meet the Maximum Time Limit, it can be immediately declared operable. The valve must be immediately re-tested.

==

Description:==

Continued personnel access to the turbine building may be essential for responding to emergencies or transients which may degrade into emergencies. The turbine building is not an air-tight structure. A radioactivity release inside the turbine building would limit personnel access and eventually lead to an unmonitored ground level release. Operation of the turbine building ventilation system: helps preserves turbine building accessibility, AND assures that radioactivity in turbine building areas is discharged through a monitored release point.

(Discharged to the reactor building stack).

The "A" distractor is plausible if the applicant thinks that since there is equipment, that may be operated in the Turbine Building, then equipment availability is the reason. The second part is correct.

The "C" distractor is plausible if the applicant thinks that since there is equipment, that may be operated in the Turbine Building, then equipment availability is the reason. The second part if the applicant remembers that SBGT system discharges to the Main Stack and since the Turbine Building Ventilation will be processing the TB atmosphere, that it will discharge to the Main Stack as well.

Description:==

31GO-OPS-005-0 states that for a normal DW entry, the maximum reactor power is 10% and step 6.4.2 requires a containment entry tagout must be established.

The "A" distractor is plausible if the applicant remembers 15% reactor power is the power level which requires the Drywell to be de-inerted. The second part is correct.

The "C" distractor is plausible if the applicant remembers 15% reactor power is the power level which requires the Drywell to be de-inerted. The second part is plausible if the applicant does not remember the requirement for a Normal entry and thinks the tagout will only be required for an Abnormal entry.

2011 Hatch 301 DRAFT IF any condition exists requiring entry into the EOPs WHICH is NOT a direct result of the SBO OR of actions taken per this procedure, THEN EOP actions must take precedence, AND this procedure is to be used for guidance ONLY.

With Torus pressure 11 psig, more than a station blackout, currently exists which will require actions in the EOPs to take precedent over the station black procedure actions. 34AB-R22-003-2 states, IF power is restored to more than one of the 4160V AC Emergency busses, THEN exit this procedure.

The "A" distractor is plausible if the applicant confuses the note and thinks that since a Station Black does exist that the station black procedure will take precedent over the EOPs. The second part is plausible since it is correct.

The "B" distractor is plausible if the applicant confuses the note and thinks that since a Station Black does exist that the station black procedure will take precedent over the EOPs. The second part is plausible if the applicant confuses the requirement to exit the procedure and thinks it takes all three emergency buses energized to leave the procedure.

The "C" distractor is plausible since the first part is correct and the second part is plausible if the applicant confuses the requirement to exit the procedure and thinks it takes all three emergency buses energized to leave the procedure.
