QUESTIONS REPORT for ILT 37 RO BANK VER 4
- 1. 001A3.06 001 Unit 1 is at 100% power with the following conditions:
- Rods are in manual.
- Control Bank D is at 225 steps.
- Median Tavg is 568.5°F.
- Tref is 571.0°F.
Subsequently, the operator places the ROD CONTROL BANK SELECTOR SWITCH in AUTO.
Which one of the following completes the statement below?
Rod Speed will indicate (1) and Control Bank D will (2) .
(1) (2)
A. 40 steps per minute remain at 225 steps B. 40 steps per minute begin to move out C. 8 steps per minute remain at 225 steps D. 8 steps per minute begin to move out Monday, July 14, 2014 10:36:33 AM 1
QUESTIONS REPORT for ILT 37 RO BANK VER 4 Distracter Analysis:
A. Incorrect 1. Incorrect. See C.1. Plausible because, rod motion begins at 1.5 degree mismatch between Median Tave and Tref with a constant rod speed of 8 step per minute until it surpasses a 1.5 degree dead band and begins to increase linearly between a 3 degree (8spm) and 5 degree (72spm) mismatch. Novice students often omit this dead band when predicting rod speed. 571 - 568.5 = 2.5 (incorrectly applying the 1.5 degree deadband results in) 2.5 - 1.5 = 1 degree. 1 degree = 40 steps per minutes
- 2. Correct. see C.2 B. Incorrect. 1. Incorrect. See A.1.
- 2. Incorrect. See C.2. Plausible because temperature difference is 2.5 degrees. Auto rod control normally would pull rods until temp difference is 1 degree. Only because rods are above 220 steps on bank D do they not move.
C. Correct. 1. Correct. Auto rod speed is 8 steps per minute from 1.5 - 3 degrees off of Tref, then from 3 - 5 degrees it increases linearly to 72 steps per min.
- 2. Correct. Rod stop at >220 steps prevents automatic rod withdraw.
D. Incorrect. 1. Correct. See C.1.
- 2. Incorrect. See B.2.

QUESTIONS REPORT for ILT 37 RO BANK VER 4
- 2. 001AG2.4.6 002 The following conditions exist on Unit 1:
At 1000:
- Rod control is in AUTO.
- TI-408A, Tavg - Tref deviation, indicates 0°F and stable.
- Pressurizer level is stable.
- Reactor Power is approximately 75% and stable.
- Control Bank D step counters are at 144 steps.
At 1002:
- TI-408A, Tavg - Tref deviation, indicates +2°F and rising.
- Pressurizer level is slowly rising.
- Pressurizer spray valves have throttled open.
- Reactor Power is approximately 76% and slowly rising.
- Control Bank D step counters are at 150 steps and stepping out.
- There is no load change in progress.
Which one of the following completes the statement below?
The event in progress is an (1) and the action required is to (2) .
A. 1) uncontrolled continuous Control Rod withdrawal
- 2) trip the reactor and enter EEP-0, Reactor Trip or Safety Injection B. 1) uncontrolled continuous Control Rod withdrawal
- 2) place the rod control mode selector switch to MANUAL and verify that rod motion stops C. 1) inadvertent RCS boration
- 2) trip the reactor and enter EEP-0, Reactor Trip or Safety Injection D. 1) inadvertent RCS boration
- 2) place the rod control mode selector switch to MANUAL and match Tavg with Tref by inserting rods Monday, July 14, 2014 10:36:33 AM 4
QUESTIONS REPORT for ILT 37 RO BANK VER 4 Distracter Analysis:
A. Incorrect. 1. Correct. See B.1.
- 2. Incorrect. See B.1. Plausible since the stated action if rods do not cease moving once they have been placed in manual IAW AOP-19. Also, a conservative action may be chosen to trip the reactor, but this would not be in accordance with AOP-19.0 for this situation, nor would it be necessary.
B. Correct. 1. A CRW is taking place as indicated by the Tavg/Tref meter value going up above +1.5 and continuing to increase. This shows rods should actually be moving to lower the high temperature.
- 2. Per AOP-19, and the action is to place rods in Manual if they are stepping while in AUTO.
C. Incorrect. 1. Incorrect. See B.1. Since for an inadvertent boration, Tavg/Tref mismatch would be less than -1.5 (with rods to be moving outward) and power would be less than 75% instead of 76%. Plausible, since rods would be moving out and Tavg/Tref mismatch could be increasing (which would cause Przr level to rise and spray valves to throttle open) with an inadvertent boration.
- 2. Incorrect. See A.2.
D. Incorrect. 1. Incorrect. See C.1.
- 2. Incorrect. See B.2. Per AOP-19, and the action is to place rods in Manual if they are stepping while in AUTO and for this type of failure the action would be to match Tavg with Tref by inserting rods. Since this is not the failure mechanism, this is not a correct answer. Plausible since if an inadvertent RCS boration was in progress, then this action would be correct.

- 3. 003K6.02 003 Unit 1 is at 45% power with the following conditions:
- DC2, RCP #1 SEAL LKOF FLOW HI, is in alarm.
- 1C RCP #1 seal leakoff flow is 6.5 gpm.
- DC5, 1C RCP #2 SEAL LKOF FLOW HI, is NOT in alarm.
Which one of the following describes actions required in accordance with AOP-4.1, Abnormal Reactor Coolant Pump Seal Leakage?
A. Trip the reactor, secure 1C RCP and close the seal leakoff valve.
B. Perform a controlled shutdown while monitoring seal flows and temperatures for degradation, then secure 1C RCP and close the seal leakoff valve.
C. Continued power operation is allowed, maintain 6-13 gpm seal injection flow, monitor 1C RCP seal flows and temperatures for degradation.
D. Continue power operation for a maximum of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, maintain >9 gpm seal injection flow, inform OPS Director to obtain vendor and engineering support.
Per AOP-4.1 Step 9, based on the indications in the stem, a controlled shutdown is required.
Distracter Analysis:
A. Incorrect. See B. Plausible since this is the action if #1 seal leakoff exceeds 8 gpm.
B. Correct. Correct per AOP-4.1. This is correct for #1 seal leakage of between 6 - 8 gpm and #2 seal leakage not in alarm.
C. Incorrect. See B. Plausible since this is the action if #1 seal leakoff was less than 6 gpm and DC5 not in alarm. Contacting the Ops Mgr would need to be performed also.
D. Incorrect. See B. Plausible since this is the action if #1 seal leakoff was less than 6 gpm and DC5 not in alarm. The 9 gpm seal injection is if a shutdown was necessary and is not correct if seal injection is < 6 gpm. The 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is to allow the #2 seal to seat but the applicant could think it allows time for vendor action on #1 seal.

CHEMICAL AND VOLUME CONTROL Excess Letdown Flow Divert Valve (8143)
A two-position switch (VCT/RCDT) controls the valve. Valve position indication lights are located above the switch. In the RCDT position, the actuation air solenoid valve is energized to position the divert valve to the RCDT. In the VCT position, the solenoid is de-energized and the valve is positioned to direct flow to the VCT.
Excess Letdown Flow Control Valve (HCV-137)
This valve is controlled by REMOTE/MANUAL setpoint station HIK-137. Fully open corresponds to a station setpoint setting of 0%.
Seal Injection Flow Control Valve (HCV-186)
This valve is controlled by REMOTE/MANUAL setpoint station HIK-186. Fully open corresponds to a station setpoint setting of 100%.
Letdown Heat Exchanger Discharge Temperature Control Valve TV-3083 ( also called TCV-144 and TCV-3083 )
The control valve is controlled from a MANUAL/AUTO (MA) station TK-144. In AUTO control, the MA station potentiometer should be set at 3.30, which corresponds to 100°F. The setpoint is variable from 50°F to 200°F (which corresponds to 0.0 to 10.0 on the potentiometer). In MANUAL control, an output of 100% corresponds to the valve being fully closed. Both Units have procedural guidance for controlling Letdown Temperature on TV-3083 manual bypass valve OR by placing TV-3083 operator on the manual jacking device.
Pressure Control Valve (PCV-145)
This valve is controlled by MA station PK-145. In AUTO control, the MA station should be set to maintain between 260 and 450 psig. The setpoint is variable from 0 to 600 psig (which corresponds to 0.0 to 10.0 on the potentiometer). In MANUAL control, a controller output of 100%
corresponds to the valve being fully closed.

- 6. 005K5.02 006 Unit 1 has just entered Mode 4 with the following conditions:
- RCS cooldown is in progress for a refueling outage.
Which one of the following completes the statement below?
Per SOP-7.0, Residual Heat Removal System, use only one train of RHR for cooldown when RCS temperature is >225°F to prevent ________ .
A. excessive heatup of the CCW system B. exceeding maximum RCS cooldown rate C. loss of both RHR pumps due to steam voiding on a Safety Injection D. violating low temperature overpressure protection (LTOP) requirements SOP-7.0 3.24 Operation of a train of RHR aligned in cooldown operation when RCS temperature is greater than 225°F will result in the associated train of ECCS being declared inoperable. One train of ECCS must be operable in Mode 4 (TS 3.5.3).
(RER C101206101).
n Distracter Analysis:
A. Incorrect. See C. Plausible because this is part of P&L 3.4 and the applicant could reason that since the "Off Service" train of RHR is normally used for cooldown, excessive heatup could be an issue because the off service train would have a lower heat load..
B. Incorrect - See C. Plausible since two trains would significantly increase cooldown capability.
C. Correct - Per P&L 3.24 D. Incorrect - See C. Plausible. LTOP is not used for cooldown but the requirement for LTOP (2 relief valves aligned) coupled with single train cooldown requirement above 225°F makes this is a common misconception about LTOP (Low temperature Over Pressure) as to when it is required to be aligned and how many trains must be aligned. (Note prior to step 4.5.1)

Question History: NEW K/A match: Candidate must recall a caution from RHR procedure that warns of making both RHR trains inoperable due to temperature of water in the suction lines causing vapor lock of the pumps.(loss of Subcooling)
SRO justification: N/A Monday, July 14, 2014 10:36:33 AM 14
Procedure Number Ver UNIT 1 Farley Nuclear Plant FNP-1-SOP-7.0 103.0 11/30/2013 RESIDUAL HEAT REMOVAL SYSTEM Page Number 13:38:40 7 of 205 3.14 At Refueling Cavity levels greater than or equal to 153'8", water can enter the Refueling Cavity Ventilation ductwork resulting in a spill in containment.
3.15 RCS Level Monitoring System level transmitter, N1B13LT2965A, has an auto ranging switching circuit associated with its output. The indication on LI 2965A is invalid when cavity level is greater than 136'.
3.16 When RCS pressure is less than 50 psig, the time operating at greater than 3300 gpm through the cold leg injection lines should be minimized to reduce the potential for pipe thinning from possible cavitation downstream of the orifices.
(Ref. ABN 95-0-0722).
3.17 In order to prevent exceeding 110% of RHR design discharge pressure during an RCS over pressurization event; the minimum allowable flowrate, for Unit 1, is 1750 gpm when the RHR loop is aligned to the RCS. This limitation would not be applicable when RCS over pressurization is not feasible (i.e., with the reactor vessel head removed, midloop, Reactor Vessel Cover installed, etc.
Reference:
Westinghouse letter ALA-95-580).
3.18 When operating an RHR pump at a reduced flowrate, the time operating less than 2750 gpm should be minimized, when practical, to reduce thrust loading of the RHR pump thrust bearing. (IN 93-08; NMS-93-0181) 3.19 Indicated RHR flow is less than actual as temperature increases above 120°F.
FE605A & B is calibrated for 100°F. For example at 300°F and 3000 gpm indicated there is a negative bias of 2.42% of full scale (5000 gpm) or an actual flow of 3121 gpm. (REA 95-0886, Rev. 1) 3.20 The Technical Specification maximum lift pressure for the RHR pump suction relief valves (Q1E11V015A&B [8708A&B]) is 450 psig. Due to setpoint tolerances, lift could occur as low as 427 psig.
3.21 If in Mode 6, then maintain greater than or equal to 3000 gpm flow in the RHR loop required to be in operation.
3.22 The RHR HX DISCH VLV (603) AND RHR HX BYP VLV (605) should NOT be closed at the same time while the RHR pump is running since this will isolate the RHR pump miniflow path FCV-602. This will cause the RHR pump to be running against shutoff head.
3.23 If possible when securing an RHR pump for the last time prior to Mode 4 entry, the pump shaft should be observed locally for smooth coast down of the pump. If the shaft exhibits jerky motion, stops abruptly, or unusual scraping or grinding noises are heard, it could be an indication of casing ring cap screws in contact with the pump impeller. SS should be notified immediately (IN 2003-03, Vogtle LER 2-2002-01).
3.24 Operation of a train of RHR aligned in cooldown operation when RCS temperature is greater than 225°F will result in the associated train of ECCS being declared inoperable. One train of ECCS must be operable in Mode 4 (TS 3.5.3).

Procedure Number Ver UNIT 1 Farley Nuclear Plant FNP-1-SOP-7.0 103.0 11/30/2013 RESIDUAL HEAT REMOVAL SYSTEM Page Number 13:38:40 18 of 205 CAUTION Ensure RCS temperature is less than 350°F and RCS pressure less than 375 psig before aligning the RHR system to the RCS.
4.5 Placing A Train RHR System in Cooldown Operation from ECCS Standby Alignment:
NOTES To satisfy ITS 3.4.12 (LTOP), steps 4.5.1 through 4.5.10 are the steps required to align RHR reliefs (overpressure mitigation) to the RCS. Align both trains for cooldown alignment prior to exceeding step 4.5.10 to ensure LTOP conditions are established prior to starting a RHR pump. Cooldown in one loop can occur during the start of an RHR pump resulting in the cold leg temperature dropping to less than 275°F momentarily.
Using OFF SERVICE train for cooldown is preferred. , Controlling RHR Temperature During Cooldown Operation, may be used without referring to this procedure section under the following conditions:
(a) RHR has been previously aligned for cooldown per section 4.5.
(b) Temperature change of one or both RHR loops is desired.
4.5.1 Verify the following have been completed for the RHR Train being aligned:
- RHR system preparation for cooldown (Section 4.1)
NOTE The intent of defeating the SI auto start from an RHR pump is to ensure at least one RHR Train remains OPERABLE for ITS 3.5.3.
4.5.2 IF required, THEN defeat the 1A RHR Pump SI auto start per Appendix 11.
4.5.3 Verify stopped 1A RHR PUMP.
4.5.4 Verify closed 1A RHR HX DISCH VLV HIK 603A.
4.5.5 Verify closed 1A RHR HX BYP FLOW FK 605A.
4.5.6 Close RWST TO 1A RHR PUMP Q1E11MOV8809A.
4.5.7 Verify closed the following valves:
Procedure Number Ver UNIT 1 Farley Nuclear Plant FNP-1-SOP-7.0 103.0 11/30/2013 RESIDUAL HEAT REMOVAL SYSTEM Page Number 13:38:40 6 of 205 3.3 To avoid thermal shock, flow through the RHR system must be initiated slowly.
Initial flow should always be established by slowly cracking open the RHR heat exchanger bypass valves. IF RCS temperature is greater than or equal to 235°F and the RHR system is to be operated in the cooldown lineup, THEN the RHR pump should be heated up slowly. (Westinghouse ESBU-TB-96-03) 3.4 Prior to starting cooldown, ensure sufficient service water is available to CCW Heat Exchangers to prevent excessive heatup of CCW system.
3.5 During cooldown, limit the cooldown rate as follows:
3.5.1 Do not exceed cooldown limits specified in the Technical Specifications.
3.5.2 Do not exceed CCW heat exchanger outlet temperature of 120°F.
3.6 When the temperature of any RCS Cold leg is at or below 275°F, then Two RHR relief valves with lift settings of less than or equal to 450 psig shall be operable and their isolation valves, Q1E11MOV8701A & Q1E11MOV8701B and Q1E11MOV8702A & Q1E11MOV8702B shall be open; (LCO 3.4.12) or open a vent path greater than or equal to 2.85 square inches.
3.7 Prior to starting or stopping a RHR pump with the RCS under solid plant pressure control LP LTDN PRESS PK 145 must be placed in MANUAL control to prevent RCS pressure fluctuations.
3.8 Monitor RCS boron concentration to ensure adequate shutdown margin is maintained.
3.9 During solid plant pressure control with letdown from RHR, maintain RHR TO LTDN HX Q1E21HCV142 open as far as possible using HIK-142.
3.10 The only time both 1A and 1B RHR Hx to CVCS letdown isolation valves 1-RHR-V-8720A (Q1E11V013A) and 1-RHR-V-8720B (Q1E11V013B) may be open at the same time is during the shifting of LP letdown from one train of RHR to the other.
3.11 Frequent starting may damage RHR pump motors. Limit pump starts as follows:
3.11.1 Two successive starts from ambient.

3.11.3 Subsequent starts: allow 15 minutes running time or 45 minutes idle time between starts.
3.12 Leakage of RCS loop check valves may result in pressurization of the RHR system piping. Venting of this pressure to the RWST is not an acceptable means of relieving such pressure since this would result in a direct flow path from the RCS to outside of containment.

QUESTIONS REPORT for ILT 37 RO BANK VER 4
- 7. 006A4.01 007 Unit 1 was operating at 100% with the following conditions:
- 1B Charging pump is aligned to 'B' Train.
- 1B Charging pump is running.
Subsequently, an LOSP with a concurrent Safety Injection occurs and the following conditions exist:
- 22 seconds after the actuation, EB1, CHG PUMP OVERLOAD TRIP, comes into alarm.
- The AMBER light on the handswitch for the 1C Charging pump is illuminated.
Which one of the following completes the statement below?
1B Charging pump .
A. must be manually started B. will start from the LOSP sequencer C. will remain running throughout the event per design D. will start due to 1C Charging Pump tripping on overload Monday, July 14, 2014 10:36:33 AM 15
QUESTIONS REPORT for ILT 37 RO BANK VER 4 SOP-2.1:
3.32 If the on-service charging pump trips on overload, the off-service charging pump for the particular train which has two operable charging pumps will automatically start.
3.33 If 1A (1C) Charging Pump trips on overload or is racked out, 1B Charging Pump will automatically start upon safety injection or loss of offsite power.
Distracter Analysis:
A. incorrect. See D. Plausible if the applicant is unfamiliar with the sequencer timing / auto-starts and believes that the timing sequence given causes the 1B charging pump not to start automatically. The logic diagram shows that the B chg pump will auto start if, at the time of the SI/LOSP the aligned train Chg pump is either racked out or is tripped. There is also another path on the same logic diagram that shows with a 1 sec TDDO that goes to an OR box, that if the aligned train Chg pump trips, the 1B Chg pump will Auto start due to the tripped Chg pump. If a candidate does not understand the logic in detail, it is plausible that the 1B Chg pump would not auto start and would have to be manually started in this situation. This is also plausible if the Chg pump that tripped were the 1A Chg vs the 1C Chg pump since the 1B Chg pump is aligned to B Train. At FNP, several components such as CCW pumps and SFP components are labeled differently for the train they are aligned to (1A CCW pump is B Train,1A SFP pump is B Train...)
B. Incorrect. See D. Plausible because the sequencer will only start the 1B charging pump if the 1C charging pump breaker is racked out or has tripped on overload. After 22 seconds have passed the sequencer will be at about step 2 of returning equipment to service.
Once a step is complete, the sequencer signal is no longer available to start any other component on a previous step.
Charging pumps come off step 1 and this will occur about 17 seconds into the event.
C. Incorrect. See D. Plausible if the applicant fails to evaluate the LOSP then this would be a correct answer if only a SI signal is received.
D. Correct. The sequencer sequences on the 1C chg pump (unless it is racked out, then it would sequence on the 1B) after about 17 seconds (approx.12 secs for DG to start and tie on, no more than 5 secs for sequencer to start load.). Then, an overload trip of 1C will cause 1B chg pump (when aligned to same train) to auto start. In this case B Train is on service so 1B chg pump is aligned to the B train with 1C Chg pump.

3.34 In order to maintain a train operable with the dedicated pump/breaker inoperable AND racked in, the cell switch should be jumpered for the swing breaker to ensure the swing breaker will close on an auto start signal with the dedicated pump breaker racked in. Additionally, a link should be opened in the auto start circuitry of the dedicated pump to prevent an auto start of the dedicated train breaker. This arrangement should remain in place until such time the dedicated breaker is declared operable or surveillance testing is started. (AI 2008205335) 3.35 It is desired to operate a complete cycle through one charging flowpath. The Control Room Log [v1]or the UOP-2.2 or UOP-2.4 that was used for the last refueling shutdown may be consulted for previous lineup. Charging flowpath should be alternated between cycles (e.g., normal for one cycle, alternate charging for the next cycle).
3.36 ZAS injection will result in a continuous RCS dilution by as much as 1.7 gallons per hour which could result in a rise of TAVG if not compensated for by boration, rod insertion, or increasing fission product poison inventory.
3.37 Any throttle valve adjustments should be verified acceptable per SR 3.5.5.1 by performing FNP-1-STP-8.0, RCP Seal Injection Leakage Test, OR FNP-1-STP-8.1 if HCV-186 is bypassed, twice within four hours. One FNP-1-STP-8.0, OR FNP-1-STP-8.1 if HCV-186 is bypassed, should be performed with the strongest charging pump supplying flow and one FNP-1-STP-8.0, OR FNP-1-STP-8.1 if HCV-186 is bypassed, with the weakest charging pump supplying flow. The strongest and weakest charging pump can be determined by comparing data in the Surveillance Test Data Book. (Engineering Support should be contacted if assistance is required in making this determination.) If not feasible to run FNP-1-STP-8.0, OR FNP-1-STP-8.1 if HCV-186 is bypassed, using either the strongest or weakest pump (i.e. pump not capable of running or breaker racked out),
the surveillance should be run with the two available charging pumps and an admin LCO used for the inoperable pump to ensure FNP-1-STP-8.0, OR FNP-1-STP-8.1 if HCV-186 is bypassed, is run when the pump is returned to service.
3.38 Any time the letdown flow path is changed (diverting TCV-143, changing mixed bed or cation bed or BTRS line up); RCS filter radiation level may drastically change.
(OR 2-99-325) 3.39 Normally only one or two letdown orifices are in service. During periods of reduced RCS pressure, it is permissible to place a third letdown orifice in service provided letdown flow does not exceed 135 gpm or 260 - 450 psig.

The PRZR Safeties relieve to the PRT.
SOP-1.2: Step 3.5 Do not exceed PRT rupture disc pressure of l00 psig.
Distracter Analysis:
A. Incorrect. 1. Incorrect. See D.1. Plausible if the applicant thinks that there is a relief upstream of LCV-460 that will lift if the valve goes shut. They could confuse this with the conditions associated with PCV-145 failing shut. There is a relief valve downstream of the Letdown orifice isolation valves but upstream of several other letdown isolations valves such as HV 8152 and HV 8175A&B. See D-17039 SH1 and 2 and ARP-1.4. If Letdown were stopped, Pressurizer level would rise. When FCV-122 is demanded close in AUTO it will still have a flow of 18 gpm. This, along with seal injection, would cause Pressurizer level to rise.
- 2. Incorrect. See D.2. Plausible since a number of relief setpoints are 150 psig and the applicant could confuse the rupture disc setpoint with other relief setpoints. The seal return line relief is set at 150 psig.

REACTOR COOLANT PUMPS Lower Motor Guide Bearing The lower guide bearing consists of a babbit-on-steel, pivoted pad guide bearing and provides radial support for the motor. The bearing operates against a .5 percent carbon alloy steel journal.
The entire lower guide bearing assembly has been located in the 25-gallon lower oil pot, which also contains an integral heat exchanger. The oil cooler receives cooling from CCW.
Thrust Bearing, Upper Motor Guide Bearing, and Oil Lift System Refer to Figure 8. The upper bearing consists of a combination double, Kingsbury type thrust bearing (suitable for up or down thrust) and a radial guide bearing. The babbit-on-steel thrust bearing shoes are mounted on equalizing pads. The pads distribute the thrust load equally to all shoes. The radial bearing, providing radial support for the motor, consists of a babbit-on-steel, pivoted-pad type bearing. Both the radial bearing and thrust bearing operate against an alloy steel journal and thrust runner combination that is shrunk on the shaft.
The entire upper bearing assembly has been located in the upper 240-gallon oil pot. A heat exchanger cooled by CCW mounts on the side of the motor and cools the oil.
Oil circulates through the upper bearings and oil cooler by means of a series of passages drilled in the thrust runner. The series of drilled passages cause the thrust runner to act like a centrifugal pump.
In order to reduce starting torque, the thrust bearing shoes receive oil from the oil lift system before starting the motor. The oil "lifts" the thrust shoes away from the thrust runner.
The thrust bearing oil lift system includes: a 10-hp, drip-proof, three-phase, 60-cycle, 600-volt, 1800-rpm motor and oil pump; a 0 to 5000-psi pressure gauge; a pressure switch; check valves; filter; relief valve; and orifice blocks. The oil lift motor and pump mount externally on the upper part of the motor casing and normally are controlled remotely from the MCB.
A permissive interlock in the RCP motor starting circuit does not allow the motor to be started until the oil lift pressure has reached a preset value (600 psi). Oil lift pressure can be read locally at the oil lift pump by manually depressing the block valve release push button and then reading the pressure on the local gauge. The lift pump should be run for at least 2 minutes prior to starting the RCP. After the RCP has been in operation for at least 1 minute, the oil lift pump 12 OPS-62101D-52101D/40301D/ESP-52101D- Version 1

18.2 Reduce RCS pressure by opening one pressurizer PORV until one of the following three conditions occurs, then stop RCS pressure reduction.
Distracter Analysis:
A. Incorrect. 1. Incorrect. See D.1. Plausible since Aux spray will lower RCS pressure, and is normally preferred since there is no loss of RCS inventory during use, but is not available due to the fact that a SI has actuated and letdown is not available to support aux spray operation. In step 31 after the SI is reset and to control RCS pressure reduction, if there is no Spray valve available, then Aux Spray is used for the pressure reduction. Since this method is used in EEP-3.0 for different circumstances then the question asks, this makes Aux spray plausible.

- 15. 012A2.03 015 Unit 1 is at 8% power with the following conditions:
- NI-42, POWER RANGE, has failed HIGH.
- AOP-100, Instrumentation Malfunction, is in progress.
- At the step to remove the control power fuses for NI-42, the UO inadvertently removes the control power fuses for NI-36, INTERMEDIATE RANGE.
Which one of the following describes the next action(s) required?
A. Enter EEP-0, Reactor Trip or Safety Injection.
B. Re-install the instrument power fuses in NI-36 and continue in AOP-100.
C. Perform the actions required by annunciator FB1, IR LOSS OF DET VOLTAGE, for NI-36.
D. Restore NI-36 to operation in accordance with SOP-39.0, Nuclear Instrumentation System.
EEP-0.0 Symptoms Intermediate NI-35,36 Reference 1/2 Range High Flux (TSLB3 2-1,2-2) Surveillance (If not blocked) Test Data Book or current S.P.
Distracter Analysis:
A. Correct. Removing the fuses for N-36 causes it to de-energize resulting in a Reactor trip due to being below P-7 (1 of 2 causes a trip)
B. Incorrect. See A. Plausible if the applicant fails to recognize that pulling the fuses for N36 will cause a trip. A Rx trip would not occur if this was done at >10% power. The SS has the authority to have the fuses re-inserted and continue with the procedure. Other corrective actions would occur afterwards if the SS chose to do this.
C. Incorrect. See A. Plausible since this alarm would come in. This would be a correct answer if power was above 10% and AOP-100 was not in progress.
D. Incorrect. See A. Plausible since this procedure is used to align the drawer for operation but it doesn't give guidance for reinstalling the fuses.

QUESTIONS REPORT for ILT 37 RO BANK VER 4 A. Incorrect 1. Correct. See B.1.
- 2. Incorrect. See B.2. Plausible if the applicant incorrectly assumed that the ATS for 1-2 A DG also powered the output breaker closure ckt and the B1F sequencer. This is a common misconception.
B. Correct. 1. Correct. The automatic transfer device ensures the DG can be supplied control power from either unit if a loss of DC occurs on either unit. This allows the DG to be started and the field flashed to provide proper output.
- 2. Correct. The output breaker closing and the sequencer operation is powered only by the associated Unit DC system. This prevents the output breaker from closing and the Sequencer will not run.
C. Incorrect. 1. Incorrect. See B.1. Plausible if the applicant fails to recognize the DG start comes from the U2 LOSP. If it were only U1 LOSP then the DG would not start. Also if this were the B Train DGs, this equipment does not have an Auto transfer switch and therefore would not start.

This causes a 1 of 2 coincidence resulting in a Reactor trip.
When the1-2A DG ties back on, N32 will be restored.
The 1B inverter is normally powered from the 125 VDC bus A. The alternate power is from 208/120vAC regulated Dist panel G which is powered from 600VAC MCC 1A which receives power from the 600 VAC Load Center 1D which receives power from 4160 VAC bus 1F which is powered by either the A Train Emergency DGs or the Startup Xformers.
Distractor analysis:
A. Incorrect. 1. Incorrect. See C.1. Plausible if the applicant thinks that 2 of 2 SR is required to trip the RX.
- 2. Incorrect. See C.2. Plausible since it aligned to the alternate source and is now powered from the AC MCC directly. when the LOSP occurs, the inverter will be de-energized in the first part of this event until the DG ties back on to the emergency bus, then power will be restored to the NI.
B. Incorrect. 1. Incorrect. See A.1.

- The crew is performing ESP-0.1, Reactor Trip Response.
- Natural circulation verification is in progress.
- Two non-upperhead Core Exit Thermocouples have failed due to open circuits.

The failed Core Exit Thermocouples' output will be failed (1) and the Subcooled Margin Monitor calculation (2) be accurate.
(1) (2)
A. high will NOT B. high WILL C. low WILL D. low will NOT Monday, July 14, 2014 10:36:34 AM 50
QUESTIONS REPORT for ILT 37 RO BANK VER 4 OPS-31701G The thermocouple operates on the principle that a voltage is developed when two dissimilar metals are joined and there is a temperature difference between the sensing junction and the reference junction. The voltage created causes current to flow. If an open develops, a path for current flow is no longer available, and therefore the output fails to a low temperature indication. A short circuit causes no voltage to be developed, and the thermocouple indicator fails low.
SOP-68 The normal display mode for the SMM is the CETC mode. This displays the margin to saturation (°F) using the highest core exit thermocouple (excluding upperhead) and the lowest pressure.
Distracter Analysis:
A. Incorrect. 1. Incorrect. Plausible because an RTD fails high.
- 2. Correct. See D.2. Logical connection to first part if the applicant thinks that upper-head CETC's are used to calculate Subcooling.
Also, some systems use a median signal selector such as Pzr level uses Median Tavg input so the applicant could assume the high failed CETC was "selected out".
B. Incorrect. 1. Incorrect. See A.1.
- 2. Incorrect. Plausible since this would be the result if a failed high output.
C. Incorrect. 1. Correct. See D.1.
- 2. Incorrect. See D.2. Plausible if the system used a specific CETC then the failed low CETC would cause the SCMM to read higher.
Also, the applicant could think that the CETCs are averaged which would make Subcooling read higher.
D. Correct. 1. Correct. CETCs fail low.
- 2. Correct. SCMM Uses HIGHEST temp so it would be unaffected.

3/15/2013 00:29 FNP-1-AOP-12.0 UNIT 1 RESIDUAL HEAT REMOVAL SYSTEM MALFUNCTION Revision 25.0 A. Purpose This procedure provides actions for response to a malfunction of the RHR system.
Actions in this procedure for restoring RHR PUMPs assume electrical power is available. During loss of electrical power conditions, FNP-1-AOP-5.0, LOSS OF A OR B TRAIN ELECTRICAL POWER, provides actions for restoration of electrical power which should be performed in addition to continuing with this procedure.
The first part of this procedure deals with the protection of any running RHR pump and isolation of any leakage. If a running train is maintained the procedure is exited. Credit may be taken for RCS Loops providing core cooling in place of a running train of RHR. The next portion deals with restoring a train of RHR while monitoring core temperatures. If a train cannot be restored actions are taken for protection of personnel, establishing containment closure, and provides alternate methods of decay heat removal while trying to restore a train of RHR. Alternate cooling methods include:
establishing a secondary heat sink if steam generators are available; feed and bleed cooling and feed and spill cooling.
The intent of feed and bleed cooling is to regain pressurizer level and allow steaming through a bleed path to provide core cooling. This requires that the RCS be in a configuration that will allow a level in the pressurizer.
The intent of feed and spill cooling is to allow spillage from the RCS and locally throttle injection flow to provide core cooling. This method is used when the reactor vessel head is blocked or RCS loop openings exist.
This procedure is applicable in modes 4, 5 and 6.

(Including setpoints if applicable.) (OPS-52102G05).
Question History: MOD BANK K/A match: This question evaluates candidate ability to monitor RCP seal package cooling (CCW and Seal Injection) and determine action required for loss of CCW actions for given Seal injection flowrates.
SRO justification: N/A Monday, July 14, 2014 10:36:34 AM 61
Component Cooling Water RCP. The line to each RCP splits into two lines for the oil coolers and a separate line for the thermal barrier heat exchanger.
The oil coolers can maintain acceptable oil temperatures with a maximum CCW temperature of 105°F. Flow instruments FE-3048A, B, and C (located on the outlet of the oil cooler) annunciate on the MCB on low flow. After exiting the oil coolers, the flow then passes through two motor-operated isolation valves, one inside containment (MOV-3046) and one outside containment (MOV-3182). Both of these valves are operated from the MCB.
Loss of CCW flow to the RCP motor oil coolers will cause high bearing temperatures on any running RCP within approximately two minutes.
In order to prevent overpressurization of the CCW system if a thermal barrier heat exchanger ruptures, pressure and flow are sensed on the thermal barrier CCW discharge line. The pressure sensors (PI-3184A, B, and C) signal HV-3184 to shut when pressure reaches 75 psig. Flow element FE-3045 shuts HV-3045 if the flow reaches 160 gpm. A balance of plant (BOP) annunciator for each valve alarms when instrument air supply pressure to the valve decreases to 40 psig. The CCW piping on the inlet side is protected by a check valve that prevents RCS pressure from reaching the low pressure piping.
CCW piping in containment (CTMT) from the check valve in the supply line to each RCP thermal barrier heat exchanger to downstream of HV-3045 in the combined return line is designed to withstand 2500 psig. Therefore, closure of either HV-3184 or HV-3045 can contain any high pressure reactor coolant leaking to the component cooling water side of the thermal barrier heat exchanger.
SOP-23.0 Component Cooling Water System contains instructions for reopening HV-3045 when a high differential pressure is suspected of preventing reopening the valve after auto-closure (OR 2-99-603). When operating the valve locally, do not use any mechanical leverage on the valve handwheel because damage to the pin which connects the handwheel to the valve stem may result. (OR 2-98-320)
A "P"-signal (phase B containment isolation) will close the five CCW valves associated with the RCPs (MOV-3052, MOV-3046, MOV-3182, HV-3184, and HV-3045). Only one other valve closes on a "P"-signal. That valve is the instrument air to containment valve (HV-3611).
HV-3184 and HV-3045 are air operated valves. They fail closed on loss of air pressure. A solenoid valve, for each air operated valve, energizes to vent the air from the actuator which causes 10 OPS-62102G/52102G/40204A/ESP-52102G - Ver 2

° NOTE:
- If seal cooling is lost, it will be necessary to trip the RCP(s) within two minutes for a #1 seal leak rate of 5 gpm reducing to 42 seconds for a #1 seal leak rate of 7 gpm, to ensure that the RCP(s) stop rotating prior to actuation of the shutdown seal. (#1 seal leak rate is defined as #1 seal leakoff flow plus #2 seal leakoff flow).
- IF RCP motor bearing temperatures exceed 195°F, THEN the ON SERVICE train is affected.
- Adequate CCW flow means sufficient cooling is available to maintain acceptable temperatures. (i.e. charging pumps, RHR cooling, SFP cooling, RCP's etc.)

A. down up B. down down C. up up D. up down Monday, July 14, 2014 10:36:34 AM 68
QUESTIONS REPORT for ILT 37 RO BANK VER 4 Distracter Analysis:
A - Incorrect. 1. Incorrect. See D.1. Plausible, since if the PT had failed 6 psig higher (above 2235 psig), the proportional integral controller would integrate the error signal DOWN until the PORV 444B opened and the sprays opened. Also, the spray valve controllers are controlled by the master controller and when the pressure must be increased, the demand on the Spray Valves goes down. Confusion could exist as which controller function is being described.
- 2. Incorrect. See D.2. Plausible, since the spray valve controllers are controlled by the master controller and when their demand goes up pressure goes down and the liquid density goes up. Also, steam space density does go up in this condition, and the liquid specific volume goes up (and specific volume, not density, is the value given in the steam table for the property of the liquid).
B. Incorrect. 1. Incorrect. See A.1.
- 2. Correct. See D.2. If the applicant reasoned that less pressure =
less dense.
C. Incorrect. 1. Correct. See D.1.
- 2. Incorrect. See D.2. The applicant could reason that more pressure = more dense.
D. Correct. 1. Correct. The Proportional/Integral PRZR PRESS controller senses a low pressure and the demand starts integrating higher and higher. This first causes the spray valves to close and the proportional heaters increase output. Then, the backup heaters energize.
- 2. Correct. The pressurizer liquid heats up and expands (density goes down) due to the increased heat input into the pressurizer liquid. The integral part of the controller continues to add to the error signal and PORV-445A opens due to actual pressure increasing to 2235 on PT 445. The pressure cycles around the setpoint of the PORV at 2235 psig with a higher pressurizer liquid temperature.

- Normal Control Methods
- Abnormal and Emergency Control Methods Question History: FNP 10 K/A match: To answer this question correctly, it must be recognized that for this particular malfunction of the PRZR Press control system, the pressurizer liquid heats up and expands due to pressurizer heaters energizing and sprays closing. The operational implications must also be understood in that this causes controller demand to go up (which would cause actual pressure go up until a PORV will lift: PORV-445A).
SRO justification: N/A Monday, July 14, 2014 10:36:34 AM 70
PRESSURIZER PRESSURE AND LEVEL CONTROL concentration in the pressurizer at the same value as the reactor coolant system by causing a continuous recirculation through the pressurizer. Finally, the continuous flow keeps the entire pressurizer in thermal equilibrium, preventing stratified temperature layers from causing erratic pressure control.
The two air-operated PORVs (PCV-445A and PCV-444B) each have a relieving capacity of 210,000 lbm/hr at 2485 psig. These valves are set to open at 2335 psig. During power operation, they prevent excessive pressure increases in the reactor coolant system, while minimizing the actuation of the code safety valves.
Three self-actuated pressurizer code safety valves (8010A, B, and C), each with a capacity of 345,000 lbm/hr at 2485 psig, are also installed on the pressurizer. These valves are set to open at 2485 psig. They will prevent the reactor coolant system pressure from exceeding 110 percent of its design value (2735 psig) for the worst case accident of a turbine trip without a direct reactor trip at 100 percent power.
Master Pressure Controller (PRZR PRESS REFERENCE, PK-444A)
The master pressure controller (Figures 3 and 4) develops control signals for the following:
- 1. Variable (Proportional) heaters
- 2. Back-up heater control bistable
- 3. Spray valves (PCV-444C and PCV-444D)
- 4. One power-operated relief valve (PCV-444B)
- 5. Control pressure high annunciator The pressure input to the master pressure controller channel is from pressurizer pressure detector PT-444. This pressure input is compared with an operator-selected pressure setpoint to give an error signal. The error signal produced is processed through a proportional-plus-integral (P+I) controller, where the error signal is conditioned to produce a compensated output.
The P portion of the P+I controller produces an output that is directly proportional to the input and is also multiplied by an amplification factor (gain). The I portion of the controller produces an output equivalent to the integral of the error signal (also known as the reset).
The longer an error exists, the larger the integral output becomes. This means that there may be an output from the integral section of the controller when there is no longer a pressure error.
4 OPS-62201H/52201H/ESP52201H- Ver2
PRESSURIZER PRESSURE AND LEVEL CONTROL The conditioned ERROR signal is developed in the pressurizer pressure master controller located in the process racks. With the master controller in AUTOMATIC (as selected by manual/auto (M/A) station PK-444A on the MCB), the reference pressure may be varied by adjusting a potentiometer dial. The potentiometer is normally set so that in automatic, the pressurizer heaters, spray valves, and PORVs will control plant pressure at 2235 psig. Variation of the reference setpoint will result in automatic control of plant pressure at a value other than 2235 psig.
The I portion of the P+I controller may cause pressure to be controlled above or below the nominal 2235 psig setpoint following a transient. The off-nominal pressure is normal following a transient. The operator should not adjust the setpoint on the M/A station during these transients. Indication of control demand is shown by a meter on PK-444A. On this meter, indication going towards zero percent means the system is trying to lower pressure, and indication going towards 100% means the system is trying to raise pressure.
Selecting MANUAL on PK-444A allows the operator to directly control components such as pressurizer spray valves and pressurizer heaters. In MANUAL, the normal automatic controller output is interrupted, and the output depends on two manual push buttons on PK-444A. The INCREASE push button causes the controller to raise pressure, while the DECREASE push button causes the controller to lower pressure. This signal is neither rate nor integral compensated. As will be seen in the discussion of individual components, a control demand less than 50 percent in either AUTO or MANUAL is a demand to lower plant pressure.
A control demand greater than 50 percent is a demand to raise plant pressure.
The variable heaters control reactor coolant system pressure during steady-state operation and are operated by a two-position ON/OFF switch located on the MCB. This switch is normally selected to the ON position, which closes the variable heater circuit breaker at the 600V LC M. A silicon-controlled rectifier (SCR) is between the variable heater circuit breaker and the heaters themselves. This solid-state device determines the voltage of the electrical power delivered to the variable heaters.
The SCR controller receives a control input from the master pressure controller channel.
When the control input is high (the actual pressure is less than the setpoint), the heaters will receive the full voltage from the SCR controller. When the control input is low, the SCR controller does not allow current flow to the heaters. The control signal to the SCR operates in a band equivalent to a +/- 15 psig error (2220 to 2250 psig if the AUTO set point is 2235 psig).

A. Incorrect. 1. Correct. See B.1.
- 2. Incorrect. Plausible since the dampers shut it would be expected the fans stopped.
B. Correct. 1. Correct. Per the FSD the manual Phase A will shut the dampers.
- 2. Correct. The fans will NOT stop.
C. Incorrect. 1. Incorrect. See B.1. Plausible if the applicant reasons that an SI signal causes the isolation and not the phase A isolation signal.
The reason the rad monitors are not in alarm is to make the will not stop rising plausible. There are two signals that isolate the Main exhaust plenum and one is Phase A isolation, the other is high rad levels.
- 2. Incorrect. Plausible if the applicant reasons that the SI closes the dampers or the rad monitors not being in alarm will not cause the dampers to go shut, however the Phase A stops the fan to protect the exhaust plenum from rupture.
D. Incorrect. 1. Incorrect. See C.1.
- 2. Correct. See B.1. Plausible if the applicant reasons that since the valves are not closed for this selection, then the fans would not stop either until the rad monitors come into alarm.

SRO justification: N/A Monday, July 14, 2014 10:36:35 AM 89
STEAM DUMPS Operational Modes TAVG-Loss-of-Load Controllers With the steam dump mode selector switch in TAVG, either of two submodes--loss-of-load and plant trip --can control the steam dump system (Figure 7). The loss-of-load controller varies the valve positioning signal in direct proportion to the temperature deviation between TAVG and Tref. The TAVG signal is from output of the median signal selector. In order to provide anticipatory response on TAVG transients, a lead-lag circuit is used. This circuit accounts for delay times in RCS temperature detection and for loop transit times. In other words, if plant temperature is increasing, the lead-lag circuit knows that actual temperature is higher than it is sensing. The rod control system uses this same compensated TAVG signal.
The steam dump system and the rod control system establish their own Tref signals, using turbine load as sensed by first stage turbine impulse pressure transmitters PT-446 and/or PT-447.
The reference temperature programs range from no-load temperature (547qF) to full-load temperature (573qF for unit 1 cycle 19). The rod control system positions the control rods in accordance with the deviation between the median TAVG signal and Tref as determined by PT-446 or PT-447. The steam dump system positions the steam dump valves according to the deviation between median TAVG and Tref as determined by PT-446 only. There is a 4qF dead band associated with steam dump system response in TAVG mode to first give rod control an opportunity to return TAVG to Tref.
The steam dump PT-446 Tref signal is not compensated in any manner. The TAVG and Tref signals are inputs to a comparator whose output is proportional to the deviation between TAVG and Tref. The deviation signal is converted to a valve positioning demand signal in the loss-of-load controller. The positioning signal is passed onto the I/P converters, provided train B of reactor protection has not sensed a Reactor Trip and provided the steam dump mode selector switch is selected to the TAVG position. If the TAVG input were to fail high to the comparator, the valve positioning demand signal would increase. If the Tref signal failed high due to PT-446 failing high, the valve positioning demand signal would decrease. Conversely, if the Tref signal failed low due to PT-446 failing low, the valve positioning demand signal would increase.
The characteristics of the loss-of-load controller are expressed in terms of percent steam flow versus the deviation between TAVG and Tref in degrees (refer to Figure 8). The loss-of-load controller is the steam dump system's main component that links the process instrumentation to the steam dump system. Because of this connecting link, the TAVG loss-of-load submode functional requirements are accomplished through the loss-of-load controller. In particular, this 8 OPS-62201G/52201G/ESP-52201G Ver 3
STEAM DUMPS controller's temperature deviation control band ensures that a 50-percent load rejection does not cause a reactor trip associated with TAVG or cause any steam generator code safety valve actuation.
To ensure that these functions are accomplished, a proper evaluation of the loss-of-load controller temperature deviation band is performed. This temperature deviation control band is evaluated as two separate parts. For the first part, a dead band 'T is evaluated. This dead band
'T is large enough that it allows some rod control system response. The dead band 'T is also small enough that quick steam dump valve response limits the transient peak TAVG value below any reactor trip values, and the steam dump system subsequently lowers the 'T into the rod control system 'T program band. Therefore, the loss-of-load controller dead band 'T is adjusted to 4qF.
The second evaluated part of the loss-of-load controller temperature deviation control band is its proportional 'T band. This proportional 'T band actively modulates the steam dump valve banks from their fully closed to their fully open positions.
In actual application, the loss-of-load controller proportional 'T band is 10.0qF The proportional band 'T limits the transient peak TAVG value after the selected dead band 'T is exceeded. The dead band 'T and the proportional band 'T provide an overall 14qF loss-of-load controller temperature deviation band.
The loss-of-load controller output feeds four signal circuits. Each signal circuit is adjusted to respond to specific loss-of-load controller output signal values. Each signal circuit, in turn, feeds the I/P converters associated with one steam dump valve bank. Through these signal circuits, the load rejection controller linearly modulates the four steam dump valve banks in their proper sequence. The following table lists the resultant steam dump valve bank response as the loss-of-load controller 'T changes.
BANK LOAD REJECTION 'T RESPONSE Bank Fully Closed Fully Open 1 4.0°F 6.5°F 2 6.5°F 9.0°F 3 9.0°F 11.5°F 4 11.5°F 14.0°F 9 OPS-62201G/52201G/ESP-52201G Ver 3
STEAM DUMPS TAVG-Plant Trip Controller When the steam dump mode selector switch is selected to the TAVG position and train B of reactor protection has sensed a Reactor trip, the output of the plant trip (Figure 7) controller is automatically lined up to the I/P converters. Conversely, the output of the loss-of-load controller is automatically blocked. In this TAVG-plant trip submode of operation, the positioning signal strength varies in direct proportion to a temperature deviation between the output of the Tavg median signal selector and Tno-load. The same compensated; median TAVG signal used in the loss-of-load submode is also used here. The Tno-load signal (547qF) is a fixed signal. TAVG and Tno-load are inputs to a comparator whose output is converted to a positioning demand signal in the turbine trip/plant trip controller. The characteristics of this controller are also expressed in percent steam flow versus the deviation degrees between TAVG and Tno-load (refer to Figure 9).
Failure of a TAVG channel high would not affect the steam dumps due to the median signal selector, which would auctioneer out the high signal.
The plant trip controller provides the same process instrumentation to steam dump system link as the loss-of-load controller. The plant trip controller accomplishes this link for the TAVG-turbine trip submode. Because the rod control system reactivity control is not available, the plant trip controller ensures that following the reactor trip, the steam generator code safety valves do not actuate, and TAVG will trend toward its no-load value.
The plant trip controller temperature deviation band evaluation is a simple process.
Without the rod control system, no dead band 'T is required. The proportional band is 28qF 'T.
The plant trip controller output controls the steam dump valve signal circuits. Therefore, the plant trip controller output operates the steam dump valve banks according to the temperature changes listed in the following table.

- 2. Incorrect. See C.2. Plausible since the applicant would not want to insert rods any more (AOP-17 directs rods inserted to match Tavg/Tref) so this would allow rods to be withdrawn. AOP-19 has a step (step 4 RNO) to restore RCS to programmed value by adjusting turbine load or boron concentration. Since this is a strategy being used in a different procedure for restoring RCS Tavg to programmed value it makes this distracter plausible.

QUESTIONS REPORT for ILT 37 RO BANK VER 4 Automatic Turbine trip occurs at 4.351 psia. At 40% power, a reactor trip occurs enabling the Plant Trip Controller.
8 inches of Hg vacuum is 10.8 psia.
See references Figure 2, Sheet 10 of FSD-A181007.
Distracter analysis A. Correct. First part is correct. A turbine trip results which causes a reactor trip, thus enabling the plant trip controller.
Second part is correct. C-9 is NOT enabled at 12 psia therefore the steam dumps do not operate and are closed.
B. Incorrect. First part is correct (See A.1).
Second part is incorrect (See A.2) Plausible if the applicant cannot recall that the vacuum setpoint for the C-9 interlock is <10.8 psia and believes that adequate condenser vacuum exists for steam dump operation.
C. Incorrect. First part is incorrect (See A.1). Plausible if the applicant fails to recognize that the turbine trip causes a reactor trip at this power. If rx power were less than 35% then a rx trip would not occur and the turbine trip would cause the LOL controller to be the controlling controller.
Second part is correct (See A.2).
D. Incorrect. First part is incorrect (See C.1).

CONDENSATE AND FEEDWATER A circulating water leak into the tube sheet area can be detected by opening the condenser tube sheet seal water flushing connection valve and having the chemistry group analyze the sampled water for impurities.
Condenser Air Removal System The air removal system (Figure 3) used for the condenser consists of two separate systems piped to a common suction header. One system is the Hogger system, and the other system is the SJAE system. The Hoggers, which are high volume air removal equipment, establish the initial vacuum in the condenser and are used only during plant startup. Once steam is admitted to the condensers, the SJAEs maintain the condenser vacuum and remove air in-leakage and noncondensible gases. The SJAEs are low volume air removal equipment. In order to operate the condenser air removal system, the gland sealing steam system must be in operation to draw a vacuum on the condenser.
The common suction header (the air ejector suction line) connects to condensers A and B via four lines. Each line has a manually operated gate valve.
The Hogger system consists of two single-stage air ejectors supplied with steam from the auxiliary steam system. A pressure control valve maintains the steam supplied to each Hogger at 125 psig. The pressure control valve and air-operated condenser suction valves for each hogger are controlled by a single switch on the MCB.
The Hoggers are used during plant startup (when main steam is not available) and can attain 27.75 inches Hg vacuum. Air and gases ejected by the Hoggers are released to the atmosphere on the roof of the turbine building.
The SJAE system includes two twin elements, two-stage SJAEs. These ejectors have two inner-condensers and one after-condenser. These SJAE condensers are used to condense the steam that is ejecting the air and gases, so that only air and the non-condensible gases are ejected to the atmosphere. Each SJAE can remove 20 cfm of 70°F dry air with a 1 inch Hg absolute backpressure. The SJAEs' inner-condensers and after-condensers receive 1400 gpm cooling water from the condensate system. Steam may be supplied to the SJAEs from the main or auxiliary steam system via separate selector switches on the MCB.

2C DG tagged out stem justification Bases knowledge required to eliminate 2C DG as a qualified power AC Sources Shutdown source. B 3.8.2 See highlighted areas on this page and the next page BASES APPLICABLE and maintenance activities must be conducted provided an SAFETY ANALYSES acceptable level of risk is not exceeded. During MODES 5 and 6, (continued) performance of a significant number of required testing and maintenance activities is also required. In MODES 5 and 6, the activities are generally planned and administratively controlled.
Relaxations from MODE 1, 2, 3, and 4 LCO requirements are acceptable during shutdown modes based on:
- a. The fact that time in an outage is limited. This is a risk prudent goal as well as a utility economic consideration.
- b. Requiring appropriate compensatory measures for certain conditions. These may include administrative controls, reliance on systems that do not necessarily meet typical design requirements applied to systems credited in operating MODE analyses, or both.
- c. Prudent utility consideration of the risk associated with multiple activities that could affect multiple systems.
- d. Maintaining, to the extent practical, the ability to perform required functions (even if not meeting MODE 1, 2, 3, and 4 OPERABILITY requirements) with systems assumed to function during an event.
In the event of an accident during shutdown, this LCO ensures the capability to support systems necessary to avoid immediate difficulty, assuming either a loss of all offsite power or a loss of all onsite diesel generator (DG) power.
The AC sources satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii).
LCO One offsite circuit capable of supplying the onsite Class 1E power distribution subsystem(s) of LCO 3.8.10, "Distribution Systems Shutdown," ensures that all required loads are powered from offsite power. An OPERABLE DG (1-2A, 1C, or 1(2)B), associated with the distribution system train required to be OPERABLE by LCO 3.8.10, ensures a diverse power source is available to provide electrical power support, assuming a loss of the offsite circuit. Together, OPERABILITY of the required offsite circuit and DG ensures the availability of sufficient AC sources to operate the unit in a safe manner and to mitigate the consequences of postulated events during shutdown (e.g., fuel handling accidents).
(continued)
Farley Units 1 and 2 B 3.8.2-2 Revision 0
AC Sources Shutdown B 3.8.2 BASES LCO The qualified offsite circuit must be capable of maintaining rated (continued) frequency and voltage, and accepting required loads during an accident, while connected to the Engineered Safety Feature (ESF) bus(es). Qualified offsite circuits are those that are described in the FSAR and are part of the licensing basis for the unit.
Two physically independent circuits between the transmission network and the onsite system may consist of any combination that includes two of the six transmission lines normally supplying the 230 and 500 kV switchyards and both independent circuits from the 230 kV switchyard to the Class 1E buses via Startup Auxiliary Transformers 1A (2A) and 1B (2B). The two of six combination of transmission lines may be shared between Unit 1 and 2. If either of the transmission lines are 500 kV, one 500/230 kV Autotransformer connecting the 500 and 230 kV switchyards is available. If both of the transmission lines are 500 kV, both 500/230 kV Autotransformers connecting the 500 and 230 kV switchyards are available. Any combination of 500 and 230 kV circuit breakers required to complete the independent circuits is permissible.
The DG must be capable of starting, accelerating to rated speed and voltage, and connecting to its respective ESF bus on detection of bus undervoltage. This sequence must be accomplished within 12 seconds. The DG must be capable of accepting the required loads manually, and continue to operate until offsite power can be restored to the ESF buses. These capabilities are required to be met from a variety of initial conditions such as DG in standby with the engine hot and DG in standby at ambient conditions.
Proper sequencer operation to sense loss of power or degraded voltage, initiate tripping of ESF bus offsite breakers and initiate DG start and DG output breaker closure and sequencing of shutdown loads are required functions for a DG to be considered OPERABLE.
It is acceptable for trains to be cross tied during shutdown conditions, allowing a single offsite power circuit to supply both required trains.
APPLICABILITY The AC sources required to be OPERABLE in MODES 5 and 6 and during movement of irradiated fuel assemblies provide assurance that:

A. rise due to the turbine ramp down B. rise due to shrink in the Steam Generators C. lower due to the turbine ramp down D. lower due to swell in the Steam Generators Distracter Analysis:
A. Correct. SG pressure goes up due to the turbine ramp down and the resulting RCS cold leg temperature rise.
B. Incorrect. SG pressure goes up and candidate without detailed knowledge may associate that with shrink in the SG, but shrink is a result of the pressure rise, not the cause of the pressure rise.
C. Incorrect. Plausible because candidate without detailed knowledge may think SG pressure goes down as you ramp down and cool down the RCS. Tavg actually goes down, but cold leg temperature goes up resulting in pressure rise in the SG.
D. Incorrect. Plausible because candidate may assume temperature and pressure in the SG will go down due to the ramp down. As pressure goes down, swell may occur and candidate may associate this with the ramp down.

STEAM GENERATORS Main Steam Atmospheric Relief Valves An atmospheric relief valve provided for each steam generator has been placed in the same location as the code safety relief valves. The atmospheric relief valves (PV-3371A, B and C) normally operate to prevent operation of the safety valves during relatively mild transients.
Following safety valve actuation, the atmospheric relief's act to assist the safety valves to positively reseat by reducing steam pressure to a value below the safety valve reseating pressure.
The reliefs also provide the capability for the removal of reactor decay heat when the main condensers are not available. An AUTO/MANUAL SETPOINT STATION may control the atmospheric relief valves from the MCB or hot shutdown panel (HSP). The main steam line penetrations and associated valves will be discussed in detail in the Main and Reheat Steam lesson plan.
STEAM GENERATOR OPERATING CHARACTERISTICS SHRINK AND SWELL Shrink and swell are steam generator phenomena that are characterized by a change in water level following a change in steam flow. Shrink is a reduction in water level following a reduction in steam flow, while swell is just the opposite.
The rate of heat transfer across the tubes can be calculated using the following equation:
Q = UA ( Tavg Tstm ).
Where:
Q = Rate of heat transfer , BTU / hr U = Overall heat transfer coefficient , BTU / hr ft 2 ° F A = Area of heat transfer surface, ft 2 Th + Tc Tavg = Avg . temperature of primary coolant =
2 Tstm = Saturation temperature for the steam, ° F .
OPS-62101C/52101C/40301C/ESP-52101C-Version 3
STEAM GENERATORS Q is proportional to the power level, or the energy being removed from the primary system to the steam generator. The heat transfer coefficient (U) remains relatively constant, and is determined by the composition and characteristics of the tubes. The area of heat transfer surface (A) is constant. If you have ever seen a pot of water boiling on a stove, you noticed that tiny bubbles of steam were formed at the hottest portions of the pot and then rose to the surface where they escaped as steam. The same thing takes place around each steam generator tube.
The rate of heat transfer or the boiling rate bubbles being formed determined the quantity of the steam. A given boiling rate (power) water mixture will have a corresponding density and specific volume. Looking closely now at an increase in power level, the following events take place:
As steam flow to the main turbine is increased, more energy will be drawn from the steam generator, which tends to decrease the steam pressure. This decrease in steam pressure causes the number and size of the steam bubbles in the boiling region to increase, which increases the steam to water ratio and specific volume, with a subsequent decrease in density. Initially, the mass of water in the steam generator remains constant, so the decrease in density will be seen as an increased steam generator water level. This phenomenon is known as "swell." The steam generator water level control system will decrease the water level to the operating band causing the mass in the generator to decrease as power level increases.
The opposite effect will be observed in the steam generator when the power level is decreased. The lower heat transfer rate along with the higher steam pressure causes less boiling to occur and a contraction of the steam bubbles present. This decreases the steam-to-water ratio with a subsequent increase in density. Since the mass in the steam generator is initially constant, the increase in density will be seen as a decrease in steam generator water level. This phenomenon has been termed "shrink."
CIRCULATION AND RECIRCULATION RATIO The moisture that is removed from the steam prior to the steam leaving the steam generator enters the downcomer region where it mixes with the incoming feedwater. Since this separated moisture, upon reaching the riser region, is making its second pass across the heat exchanging U-tubes; this moisture content is called recirculation flow. This recirculation flow OPS-62101C/52101C/40301C/ESP-52101C-Version 3

QUESTIONS REPORT for ILT 37 RO BANK VER 4 Distracter Analysis:
A. Correct 1) SG pressure will be lower at 1015. Following a reactor trip steam dumps will modulate maintain no load Tavg temperature of 547°F with an approximate SG pressure of 1005 psig. Also the secondary side is a saturated system such that RCS temperature reduction will result in a corresponding SG pressure reduction.
- 2) Flow is reduced therefore the work of the pump is reduced and backpressure on the pump increases. As the back pressure increases downstream of a centrifugal pump, energy that the pump used to put into increasing flow rate must now be used to overcome the higher pressure.
As the backpressure increases, the discharge pressure must increase.
This results in less flow rate. With less flow rate the pump does not have to work as hard and the power required will decrease.
B. Incorrect 1) 1st part is incorrect but plausible if the applicant disregards the effects of steam dump operations and believes the level increase in the SG will compress the steam bubble and raise SG pressure.
- 2) 2nd part is correct see A.2 C. Incorrect 1) first part is correct see A.1
- 2) 2nd part is incorrect amps will decrease plausible if the applicant believes the work the pump must do to overcome the higher discharge pressure will result in amps increasing.

QUESTIONS REPORT for ILT 37 RO BANK VER 4 When the Battery output breaker is opened, LA-05, WC3 will come into alarm due to the b contact from breaker LA05. WC2 shows either a low voltage condition or a ground. In this case it would be a ground.
The battery output breaker has opened due to a ground on the battery and when it opens WC2 clears. The annunciators provide indication that the breaker opened and the white light provides indication of the ground. For this set of circumstances, the battery is no longer aligned to the bus and the battery charger is carrying the load. The indications will remain normal and the inverters will have normal indications. The inverters will not swap to the bypass source and will still be powered from the battery charger.
DWG: D177082 sheet 1, U265966 A - Incorrect. First part is incorrect. See D.1. Plausible if the applicant thinks the DC bus was deenergized due to the indications given.
Second part is Correct. See D.2. Plausible connection to first part if the applicant thinks that the bypass source is supplying the inverter output.
B - Incorrect. First part is incorrect. See A.1.
Second part is correct. See D.2. Plausible connection to the first part if the applicant confused the normal and alternate power supplies to the inverter.
C - Incorrect. First part is correct. See D.1 Second part is incorrect. See D.2. Plausible if the applicant thought that when the inverter automatically shifts to the alternate source, Current indication is lost. This is correct if the inverter is manually bypassed.
D - Correct. First part is correct. When the battery breaker opens, the battery charger will supply the DC bus.
Second part is correct. The inverter is still supplying the load from the normal source. The inverter gets its power from the 125V DC bus. As long as the 125V DC buc remains energized, the inverter will stay on its normal source.

ERG StepText: Check DC Bus Loads
Purpose:
To conserve dc power supply by shedding non-essential dc loads from the dc busses as soon as practical Basis: Following loss of all ac power, the station batteries are the only source of electrical power.
The station batteries supply the dc busses and the ac vital instrument busses. Since ac emergency power is not available to charge the station batteries, battery power supply must be conserved to permit monitoring and control of the plant until ac power can be restored. A plant specific procedure should be prepared to prioritize the shedding of dc loads in order to conserve and prolong the station battery power supply. The plant specific evaluation should consider shedding of equipment loads from the dc busses and of instrumentation from the ac vital busses. The intent of load shedding is to remove all large non-essential loads as soon as practical, consistent with preventing damage to plant equipment. Consideration should be given to the priority of shedding additional loads in case ac power cannot be restored within the projected life of the station batteries. Consideration should also be given to securing a portable diesel powered battery charger to ensure dc power availability. Since the remaining battery life cannot be monitored from the control room, Step 14 requires personnel to be dispatched to locally monitor the dc power supply. This is intended to provide the operator information on remaining battery life and the need to shed additional dc loads. The plant specific procedure should be structured to ensure communications with the control room operator to ensure his knowledge of dc power status.

Inductors expand and collapse their magnetic fields in an attempt to keep current constant and capacitors charge and discharge in an attempt to keep voltage constant. Circuit inductance and capacitance consumes and gives back apparent power. The power delivered to the inductance is stored in the magnetic field when the field is expanding and returned to the source when the magnetic field collapses. The power delivered to the capacitance is stored in the electrostatic field when the capacitor is charging, and returned to the source when the capacitor discharges.
We know that alternating current constantly changes; thus, the cycle of expansion and collapse of the magnetic and electrostatic fields constantly occurs. The combined capacitive reactance (XC) and inductive reactance (XL) is net reactance (X).

5.1 General
Logs should provide an accurate history of plant operations as a narrative sequence of events or functions performed. These log entries become the tracking mechanism by which we measure Technical Specification compliance, Risk Assessment (for all modes of operations), Event analysis, and Performance Indicator assessment.
Care should be taken to ensure that pertinent data, alarms, or indications are recorded in the appropriate operator log(s) to allow reconstruction of the event.
During fast-paced transients, notes can be used until transfer to the appropriate log can be accomplished after the condition stabilizes.
The normal method of log keeping will be the use of the computerized log, with one master log program, consisting of sublogs for the applicable shift members.
Any on shift operator may make a log entry in the log of their unit log after logging in to the software. If a log entry is edited, the entry will be noted as having been edited and the person making the change will be identified.
Changes to plant equipment status that affect NRC Performance Indicators (PI) will be entered into the Control Room Log on the affected Unit. See Figure 2, Performance Indicators Primarily Controlled And Monitored By Operations for items that are under Operations responsibility for documenting. The intent of this requirement is that the Control Room Log will be the location for review for Operations PI Data Preparation.
5.2 Requirements Common To All Narrative Logs:
Significant events (e.g., trips, ESF actuations) will be included in sufficient detail so that the event is basically described.
IF an instrument is removed from service to perform a TS, TRM, or ODCM test, the out of service time will be tracked in accordance with FNP-0-SOP-0.13, Recording Limiting Conditions For Operations.
The narrative log will be shown in chronological order. WHEN necessary to insert additional information into a log that has been archived, THEN the entry will be designated as a late entry AND be noted with the actual date/time of the event in the active log.
Narrative log entries must be kept current with clear, concise, and complete entries, using the appropriate log entry type when applicable.
The "NOTES" feature of the computerized log may be used to enter miscellaneous information for shift turnover or other purposes. This is not a part of the official log.
The Shift Clerk should maintain at least the previous seven days logs in the Shift Clerks office for review by the operating crew should the electronic logs become unavailable. Then the logs shall be forwarded to Document Control for filing in accordance with FNP-0-AP-4, Control Of Plant Documents And Records.

An audit of gate times or payroll times are not an appropriate measure of 10 CFR 26 compliance since these measures may not be representative of risk-significant work activities.
6.0 Procedure 6.1 On-Line Method - Maximum Average Work Hour (MAWH) 6.1.1 MAWH is the on-line method selected for the SNC fleet for managing cumulative fatigue that establishes a limit of 54 work hours per week that an individual may average over the licensee-defined averaging period of 1 to 6 weeks. A weekly maximum average of 54 hours6.25e-4 days <br />0.015 hours <br />8.928571e-5 weeks <br />2.0547e-5 months <br /> worked, is calculated based on a rolling averaging period of up to 6 weeks.
This is an alternative approach to on-line minimum days off (MDO) and is applicable to all Covered Worker classifications.
Note The requirements for ceilings, breaks and MAWH (54-hour averaging) must be met simultaneously. Unless the calculation period falls within a partial week, then only the ceilings and breaks would apply.
6.1.2 The following work hour ceiling limits apply to covered individuals regardless of unit status unless the unit status is related to declared plant emergencies or an unannounced emergency preparedness exercise:
x No more than 16 work hours in any 24-hour period x No more than 26 work hours in any 48-hour period x No more than 72 work hours in any 7-day/168-hour period The periods of "24-hours," "48-hours," "7-days/168-hours" and 9-days/216-hours are rolling time periods. Rolling means the period is not re-zeroed or reset following a day off. The period continues to roll.
6.1.3 The following break requirements apply to covered individuals regardless of unit status unless the unit status is related to declared plant emergencies or an unannounced emergency preparedness exercise:
x At least a 10-hour break between successive work periods (an 8-hour break is acceptable only when a break of less than 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> is necessary to accommodate a crew's scheduled transition between work schedules or shifts).
x A 34-hour break in any 9-calendar day/216-hour period.
6.1.4 The averaging period is the duration over which the 54-hour average (MAWH) is calculated and will be consistent with standard shift schedules, but may not be less than 1 week or greater than 6 weeks.
x All departments will use an averaging period that will coincide with the departments standard shift schedule. Standard shift schedules could change due to Management decisions.

Ruptured 2B MS ATMOS REL VLV PC 3371B - 8.25 in AUTO Distracter Analysis:
A. Incorrect. See B. Plausible, since this is correct per EEP-2 for a faulted SG isolation.
B. Correct. See B. EEP-3 directs adjusting the SG Atmospheric Relief Valve in AUTO with controller setpoint at 8.25 to minimize radioactive releases.
C. Incorrect. See B. Plausible, since this is a value used in SOP-18, Steam Dump System, for steam dump operation during plant heatup. Step 4.1.5 and in the note prior to step 4.3.
D. Incorrect. See B. Plausible, since EEP-2 directs the ARV be placed in manual to isolate a faulted SG and additionally, skill of the craft would allow this if the automatic controller was not working correctly.
Controlling at 1035, the normal automatic setpoint, would make sense if the valve was in manual since it would prevent challenging a safety relief valve which may fail to reseat and create an unisolable release.

A. Westinghouse PERMS radiation monitoring system panels on MCB.
B. Gaseous Waste processing panel annunciator reported by the RADSIDE SO.
C. Victoreen process and effluent monitoring system panel on BOP.
D. A report from the systems operator in the area of the rad monitor.
OPS- 52106D Pg 18 Airborne Radiation Monitoring System (Figures 15 through 17)
The Victoreen airborne detectors (R-30 through 34) are completely self-contained, off-line units with no control room instrumentation or indication. The units have positive displacement pumps similar to the Westinghouse APD (Figure 16).
Distracter Analysis:
A. Incorrect. See D. Plausible because most rad monitors are part of the PERMS system and do provide indication in the Control Room or alarm on the MCB.
B. Incorrect. See D. Plausible since the R-31 is located on the 121' rad side, and the applicant may think that the alarm is part of the annunciator panel for the Waste Gas panel which is on the 100'.
C. Incorrect. See D. Plausible since R-30 and R-31 are Victoreen units, but they do not provide indication or alarm on the BOP.
D. Correct. The only way to know if R-31 is in alarm is to either check the Plant Computer or check locally.

Per EIP-1.0, Duties of an Individual who Discovers an Emergency Condition, which one of the following is required to be performed FIRST?
A. Search all elevations of the Auxiliary Building for injured personnel.
B. Report directly to the Emergency Director and provide a status report.
C. Isolate the ruptured pipe using an upstream valve from a safe location.
D. Inform the Control Room of the emergency then proceed directly to their assembly area.
EIP-1.0 4.1 An individual who discovers an emergency condition shall perform the following actions in a timely manner:
4.1.1 Withdraw to a safe place (such as evacuating from an area if a radiation monitor alarms or if radioactive contamination is involved).
4.1.2 Take actions he is qualified to perform which will aid in controlling and minimizing the effects of the emergency. Examples of such actions include:
4.1.2.1 Extinguishing a small fire with fire fighting equipment located in the immediate area.
4.1.2.2 Closing an upstream valve when a system pipe rupture has occurred.
Distracter analysis:
A. Incorrect. See C. Plausible because EIP-1 has the UO remove injured personnel and a search seems important since it would be pertaining to life saving.
B. Incorrect. See C. Plausible because it is a subsequent action of EIP-1.
C. Correct. Per 4.1.2.2 - Closing an upstream valve when a system pipe rupture has occurred.
D. Incorrect. See C. Plausible since informing the control room would be an appropriate action and proceeding to the assembly area is an action required if the plant emergency alarm is sounded. The applicant could assume that proceeding to the assembly area will allow them to be made available to the Emergency Director for dispatch.

- 71. W/E05EK1.1 071 A loss of ALL feedwater has occurred on Unit 1. The team is implementing FRP-H.1, Response to Loss of Secondary Heat Sink, and the following conditions exist:
- SI has NOT actuated.
- RCS temp is 547°F.
- Attachment 1, MAIN FEEDWATER BYPASS VALVES AUTOMATIC CLOSURE DEFEAT, has been completed.
- The red light is LIT on the following handswitches:
MOV-3232A, MAIN FW TO 1A SG STOP VLV MOV-3232B, MAIN FW TO 1B SG STOP VLV MOV-3232C, MAIN FW TO 1C SG STOP VLV Immediately upon feeding the SGs, GB5, STM LINE LO PRESS RX TRIP SI, annunciator comes into alarm.
Which one of the following completes the statements below?
The 1A SGFP (1) trip.
MOV-3232A, B, C (2) automatically close.
(1) (2)
A. will NOT will NOT B. will NOT WILL C. WILL will NOT D. WILL WILL Monday, July 14, 2014 10:36:37 AM 188
QUESTIONS REPORT for ILT 37 RO BANK VER 4 FRP-H.1 step 3 NOTE states: "If SI has not actuated since Reactor Trip, defeating the feedwater isolation signal to main feedwater regulating bypass valves will ensure the main feedwater flow path remains open. A subsequent SI will still cause the trip of an operating SGFP."
Additionally, SI would be blocked (step 7.22) however, only if < P-12.
Step 9.10 CAUTION reminds the operator that: "SI actuation circuits will automatically unblock if RCS average temperature rises to greater than 543°F or PRZR pressure rises to greater than 2000 psig."
MOV-3232A/B/C will auto close upon a trip of BOTH SGFPs AND the handswitch is in the (spring returned) Automatic Position, this closure signal is NOT bypassed by the jumpers installed by Attachment 1 of FRP-H.1.
FRP-H.1, Step 9.7.3, if feeding the SGs using the Condensate system, would de-energize the Main Feed Stop Valves in the open position. This step is only encountered however, if the SGFPs are not available to feed the SGs.
A. Incorrect. 1) Incorrect. See D.1. Plausible if the applicant thinks the jumpers will prevent a SGFP trip which is reasonable if it prevents the feed water isolation.
- 2) Incorrect. See D.2. Plausible if the applicant thinks the jumpers prevent the MOVs from closing. Also, when using condensate pumps, the MOVs are opened and powered down and the applicant may think this is true for SGFP feeding of the SGs.
B. Incorrect. 1. Incorrect, see A.1.
- 2. Correct. See D.2.
C. Incorrect. 1. Correct. See D.1.
- 2. Incorrect. See A.2.
D. Correct. 1. Correct. The SGFP will trip per the note prior to step 3.

QUESTIONS REPORT for ILT 37 RO BANK VER 4
- 72. W/E06EG2.1.20 072 FRP- C.2, Response to Degraded Core Cooling, has been entered on Unit 2. The operating crew is at the step to "Check RCP Status" and the following conditions exist:
- All RCPs are running.
- 2B RCP seal injection is 4 gpm and cannot be raised any higher.
Which one of the following completes the statement below?
Per FRP-C.2, the operating crew is required to .
A. stop 2B RCP B. stop ALL RCPs C. stop 2A and 2C RCP D. leave ALL RCPs running Monday, July 14, 2014 10:36:37 AM 191
QUESTIONS REPORT for ILT 37 RO BANK VER 4 FRP-C.2 NOTE: Since RCP damage may occur when operating RCPs without normal support conditions established or under highly voided RCS conditions, the intent of the following step is to save one RCP (which provides the best pressurizer spray capability) for future use, if all three RCPs are running.
7 Check if one RCP should be stopped.
7.1 Check ALL RCPs - STARTED 7.2 Stop RCP 2B.
7.3 Proceed to Step 9.
Distracter Analysis:
A. Correct: Per Step 7 of FRP-C.2.
B. Incorrect. See. A. Plausible since RCP support conditions are not met for any RCP.
C. Incorrect See A. Plausible since the applicant may not recall that 2B RCP seal injection is too low or that any is better than none but the oil reservoir issue requires securing the pump.
D. Incorrect. See A. Plausible if the applicant recalls that RCP support conditions are not required but fails to recall that the 2B RCP is saved for future use.

- 73. W/E08EA1.1 073 An RCS soak is in progress per FRP-P.1, Response to Imminent Pressurized Thermal Shock Condition, with the following conditions:
- RCS Pressure is 1000 psig and stable.
- RCS Cold Leg Temperature is 450°F and stable.
Which one of the following actions is permitted?
A. Start a RCP.
B. Energize PZR heaters.
D. Isolate the SI Accumulators.
FRP-P.1 28.2 IF RCS soak will not be affected, THEN perform actions of other procedures in effect.
Distracter Analysis:
A. Incorrect. See D. Plausible because A RCP is started in FRP-P.1 if possible but before the soak.
B. Incorrect. See D. Plausible since heaters are used but the pressure is stable then this would raise pressure and the applicant may think that FRP-P.1 established a pressure/temperature band for the soak.
C. Incorrect. See D. Plausible if the applicant thinks that FRP-P.1 established a pressure/temperature band for the soak.
D. Correct. This has no impact on Pressure/Temperature.

- 74. W/E11EA1.1 074 The following conditions exist on Unit 1:
- LOCA inside containment
- EEP-1.0, Loss of Reactor or Secondary Coolant, is in progress.
- 1B Charging Pump is on A Train.
Per EEP-1.0, a loss of power to which one of the following components will result in a complete loss of ECCS recirculation availability?
A. MOV-8827B, CTMT SUMP TO 1B CS PUMP B. MOV-8706B, 1B RHR HX TO CHG PUMP SUCT C. 1A RHR pump D. 1C Charging Pump Monday, July 14, 2014 10:36:37 AM 196

Incorrect. See B. MOV8827B is not required by EEP-1.0, but plausible because this MOV is required for recirc of Containment sump contents by the Containment Spray system. This answer would result in a loss of Containment spray recirculation on B train.
B. Correct. Power loss to MOV-8706B removes B train recirc capability, MOV-3185 in the stem has disabled A train recirc resulting in a complete loss of recirculation capability C. Incorrect. See B. Plausible because the 1A RHR Pump is required by EEP-1.0, but since MOV3185A is already closed in the stem A train is already lost. If MOV-3185A were capable of being opened this answer would disable A train recirculation.
D. Incorrect. See B. EEP-1.0 does not specifically require a Charging Pump to be available, although it does require an MOV8706 for RHR HX TO CHG PUMP SUCT to be available. Plausible because it would be logical to require the B Train Charging Pump to be available.

Check indications for components supplied with service water.
FRB-Z.2 Step 1.
[...] Containment flooding is a concern since critical plant components necessary for plant recovery may be damaged and rendered inoperable. [...]
Distracter Analysis:
A. Correct. 1. Correct. Per Step 1 of Z.2
- 2. Correct. Per the Bkgrnd document.
B. Incorrect. 1. Correct. See A.1.
- 2. Incorrect. See A.2. Plausible since the weight of the water would push against the inner Containment wall and the applicant may think this would challenge the structure if the water level were to get too high.
C. Incorrect. 1. Incorrect See A.1. Plausible if the applicant thought that Containment had sprinklers. There is a fire protection connection off of SW in ctmt and it would be plausible that this connection may also go to a fire header and sprinkler system. The piping for this connection is painted red like other fire protection piping so a student may not know this is a service water connection.
- 2. Correct. See A.2.
D. Incorrect. 1. Incorrect. See C.1.
- 2. Incorrect. See B.2.

ERG StepText: Try To Identify Unexpected Source Of Water To Sump:
Purpose:
To identify unexpected source of water in sump.
Basis: This step instructs the operator to try to identify the unexpected source of the water in the containment sump. Containment flooding is a concern since critical plant components necessary for plant recovery may be damaged and rendered inoperable. A water level greater than the design basis flood level provides an indication that water volumes other than those represented by the emergency stored water sources (e.g., RWST, accumulators, etc.) have been introduced into the containment sump. Typical sources which penetrate containment are service water, component cooling water, primary makeup water and demineralized water.
All possible plant specific sources which penetrate containment should be included in this step. These systems provide large water flow rates to components inside the containment and a major leak or break in one of these lines could introduce large quantities of water into the sump. Identification and isolation of any broken or leaking water line inside containment is essential to maintaining the water level below the design basis flood level.
