- 76. 2011 NRC SRO 001/BANKIC/A////EARLY SUBMITTAL/01 IE G2.4.91 Given the following plant conditions:
- The plant is in Mode 6 - An assembly is in the Manipulator Crane - A 140 gpm RCS leak occurs - The crew has adjusted Charging flow - Reactor cavity level has been stablized at 23.2 above the Reactor Flange - The crew has just entered AOP-020, Loss of RCS Inventory or Residual Heat Removal While Shutdown Which ONE of the following (1) describes the applicable procedure to be used for this condition AND (2) the required action to respond to this condition?
(RCS temperature will remain below 200°F) A. (1) Remain in AOP-020; (2) Initiate flow though the BIT B (1) Remain in AOP-020; (2) Control Charging flow though the normal charging line C. (1) Transition to AOP-031 Loss of Refueling Cavity Integrity; (2) Initiate flow though the BIT D. (1) Transition to AOP-031 Loss of Refueling Cavity Integrity; (2) Control Charging flow though the normal charging line 183
2011 HNP SRQ NRC WritterL Exam Feedback Plausibility and Answer Analysis - In Mode 6 (with refueling in progress) the Reactor Cavity level is maintained >23 above the Reactor Vessel flange. AOP-020, Loss of RCS Inventory or Residual Heat Removal While Shutdown is the appropriate AOP and the Charging line is the flowpath used in Section 3.4 for a minor RCS leak. Only 1 CSIP is available since the other CSIP would be tagged out during Mode 5. A. Incorrect. Plausible since the correct procedure is listed but the action is only performed in AOP-020 IF the leak is> 150 gpm. B. Correct. C. Incorrect. Plausible since an assembly is NOT in the safe position but transition to AOP-031 would only occur if Reactor Cavity level is decreasing or below 23. The second part is plausible but the action is only performed in AOP-031 IF the leak is> 150 gpm. D. Incorrect. Plausible since an assembly is NOT in the safe position but transition to AOP-031 would only occur if Reactor Cavity level is decreasing or below 23. The second part (action) is plausible and correct per AOP-020 orAOP-031. 184

- 77. 2011 NRC SRO 002/BANKJC/A//AOP-020//EARLY SUBMITTAL/025 AA2.021 Given the following plant conditions:
- The plant is in Mode 4 - RCS makeup capability is limited to 80 gpm - RHR Train B has been placed in service - RCS temperature is stable at 325°F RCS pressure is 320 psig and lowering - Containment sump level is 20 inches and rising - Pressurizer level is 28% and lowering The OAC responded by taking manual control of FK-1 22.1 and has increased Charging flow to 90 gpm. Pressurizer level is now stable.
Which ONE of the following describes (1) the correct procedure to address the event in progress AND (2) the mitigative actions this procedure will direct? A. (1) AOP-016, Excessive RCS Leakage (2) Stop all running RHR pumps and isolate RHR B. (1) AOP-016, Excessive RCS Leakage (2) Establish BIT flow C (1) AOP-020, Loss of RCS Inventory or Residual Heat Removal While Shutdown (2) Stop all running RHR pumps and isolate RHR D. (1) AOP-020, Loss of RCS Inventory or Residual Heat Removal While Shutdown (2) Establish BIT flow 186
2I1 I-LNP SRO NRC Written Exam-Feedback Plausibility and Answer Analysis With the plant is in Mode 4, AOP-020 is the correct procedure. For charging flow greater than 50 gpm AOP-020 will direct securing all RHR pumps and isolating RHR immediately. A. Incorrect. Plausible because entry conditions are met for AOP-016 but this procedure would not direct isolation of the RHR system but this is an action that would be correct for the conditions in AOP-020. B. Incorrect. Plausible because entry conditions forAOP-016 are met, however AOP-016 would direct operator to go to AOP-020. The second part is plausible because RCS leakage exceeds makeup capability and AOP-016 would direct actuation of Safety Injection (aligning high head SI flow through the BIT) C. Correct. D. Incorrect. Plausible because procedure selection is correct, however the second part is incorrect but plausible because RCS leakage exceeding 150 gpm would require alignment of charging through the BIT. 187

2011 HNP SRO NRC Wr#ten Exam Feedback Plausibility and Answer Analysis The 2/3 coincidence is met on the correct 3 channels for SG low-low level. The Pressurizer low pressure trip is blocked below P-7 and thus the associated first out would not be in. PA TH-I GUIDE Attachment 6 is implemented while continuing with FRP-S. I per a foldout in FRP-S. I. A. Incorrect. Plausible since the first part is correct. The seond part is plausible since Attachment 6is contained/n PATH-I Guide and verifying safeguards actuations could be considered lower priority than taking actions for an A TWS. B. Incorrect. Plausible since a Pzr low press trip would occur if above P-7 and SG level is above the setpoint on 2/4 channels and only 3 channels are used for the low-low level trip. If the wrong 3 channels are selected for coincidence the first our would not be in. The seond part is plausible since Attachment 6 is contained in PATH-I Guide and verifying safeguards actuations could be considered lower priority than taking actions for an A TWS. C. Correct. D. Incorrect. Plausible since a Pzr low press trip would occur if above P-7 and SG level is above the setpoint on 2/4 channels and only 3 channels are used for the low-low level trip.

Which ONE of the following satisfies the Tech Spec bases requirement for off-site power distribution with the plant in Mode 1? A The requirement can be satisfied by any two separate off-site transmission lines that can power the SUTs. B. The requirement can ONLY be satisfied by two off-site transmission lines that feed the SUTs directly (Cary Regency Park and Cape Fear North). C. The requirement can ONLY be satisfied by the off-site transmission lines that do not feed the respective North or South switchyard bus through a jumper. D. The requirement is satisfied as long as the switchyard alignment is such that power is available from the off-site transmission network to both SUTs regardless of the number of transmission lines available. Feedback Plausibility and Answer Analysis The minimum offsite power sources will be maintained so that at least 2 independent offsite circuits are available. Circuits may consist of any two of the incoming transmission lines to the SA Ts (either through the switchyard or directly). A. Correct. B. Incorrect. Plausible since this would meet the operability requirement, but is not the only permitted alignment. C. Incorrect. Plausible since BKR 52-16 can only be used to maintain operability of Train B power if the disconnects for 52-17 are closed with the jumpers installed, but this is an acceptable source. D. Incorrect. Plausible since a single transmission line can provide power to both SUTs, but 2 transmission lines are required for redundancy. 192

A loss of DC power ONLY will cause the alarm to annunciate. A loss of Instrument Bus Ill automatic function is loss of power to Channel Ill SG level instruments and will cause all Feed Regulating valves to fail open. IF power (AC) has not been affected then there will be no affect on SG level control. The TS 3.8.3.1 action for the inverter not being connected to its associated DC bus is to re-energized from DC within 24 hours (Action C.). A. Incorrect. The first part is correct. The second part is plausible since the action is correct if the Inst bus is not energized from its inverter (Action b.). B. Correct. C. Incorrect. The first part is plausible since the SI! and SIV inverters have a static switch that would maintain the Inst bus energized on a loss of AC and DC inputs to the inverter. The second part is plausible since the action is correct if the Inst bus is not energized from its inverter (Action b.). D. Incorrect.

Given the following plant conditions:
- The plant has experienced a Reactor Trip and Safety Injection - The crew has implemented PATH-i - A transition was made to EPP-O1 3, LOCA Outside Containment - The RAB radiological conditions are being evaluated by HP and currently HP will NOT allow any personnel entry Which ONE of the following parameters will be used to determine if the break is isolated lAW EPP-0i3, AND the procedure transitioned to when the leak is isolated?
A RCS pressure increasing PATH-I, entry point C B. Pressurizer level increasing PATH-i, entry point C C. RCS pressure increasing EPP-012, Loss Of Emergency Coolant Recirculation D. Pressurizer level increasing EPP-0i2, Loss Of Emergency Coolant Recircutation 197
2011-HNP SRO NRC Written Exam Feedback Plausibility and Answer Analysis RCS pressure increasing is the parameter that is a correct indication of the LOCA being isolated lAW EPP-013 step 7.b. Second part- EPP-013 directs a transition to PATH-I Entry Point C when RCS pressure is obtained. A. Correct B. Incorrect Plausible because the PZR level could be used to determine RCS inventory but alone is not sufficient indication of break isolation. The second part is plausible since Pressurizer level increasing could mean that the leak is isolated, but it could also mean that the SI flow is greater than the break flow or that a bubble has formed in the head region. Second part- correct since EPP-013 directs a transition to PA TH-I Entry Point C when RCS pressure is obtained. C. Incorrect Plausible because the first part is correct, RCS pressure increasing is the parameter that is a correct indication of the LOCA being isolated EPP-013 step 7.b. Second part- is incorrect, but plausible, since EPP-013 does direct to EPP-012 if the leak outside of containment is NOT isolated. This procedure would also be entered if the leak continued long enough to reduce the RWST level and the Containment accident sump level to a predetermined level. D. Incorrect Plausible because the PZR level could be used to determine RCS inventory but alone is not sufficient indication of break isolation. Pressurizer level increasing could mean that the leak is isolated, but it could also mean that the SI flow is greater than the break flow or that a bubble has formed in the head region. Second part is incorrect, but plausible, since EPP-013 does direct to EPP-012 if the leak outside of containment is NOT isolated. This procedure would also be entered if the leak continued long enough to reduce the RWST level and the Containment accident sump level to a predetermined level. 198

Given the following plant conditions:
- The plant is operating at 100% power - Pressurizer Level Instrument, LT-461, is isolated due to a leak on the transmitter - A CSIP has been under clearance for electrical inspection - Pressurizer Level Controller Selector switch is selected to 459/460 The QAC reports the following indications: - El-222, B CSIP motor amps, indicates 45 amps - P1-121, Charging HDR Press, indicates 2800 psig - Pressurizer level is lowering on Pressurizer Level Instrument LT-460 Which ONE of the following describes (1) the malfunction AND (2) the required action?
A (1) Pressurizer Level Instrument, LT-459, has failed high (2) Place the unit in Mode 3 within 7 hours B. (1) Pressurizer Level Instrument, LT-459, has failed high (2) Place Level Channel 459 in a tripped condition within 6 hours C. (1) The B CSIP has a shaft shear (2) Place the unit in Mode 3 within 7 hours D. (1) The B CSIP has a shaft shear (2) Restore one CSIP to an OPERABLE status within 72 hours 200
2G1t HNP SRO NRC Written Exam Feedback Plausibility and Answer Analysis The Charging header is monitored by a flow instrumentation ioop that operates a flow control valve. This instrumentation loop receives a signal from the PZR level control system LK-459F, which controls flow control valve FK-122. I to maintain PZR level at the desired level. With PZR level channel 460 lowering the ouput on LK-459F should be increasing to restore PZR level with increased Charging flow. Additionally, the output signal on FK-122. I should be increasing. HNP Simulator data indicated that Charging pumps amperage during full power steady state operation is approximately 47 amps with a discharge pressure of 2755 psig. With LK-459F output at 0 and FK-122. I output at 0 the Charging pump amps decreased slightly to 45 amps and discharge pressure increased slightly to 2809 psig. A. Correct. Conditions provided indicate LT-459 has failed high and T.S. 3.0.3 is applicable (1 hour to initiate action, 6 hours to Hot Standby). B. Incorrect.

Given the following plant conditions:
- The plant is operating at 100% power - Degrading Condenser vacuum was observed - CTMP-7-i, Cooling Tower I Level Hl/LO is in alarm - AOP-012, Partial Loss of Condenser Vacuum has been entered - lAW AOP-012, The Reactor has been tripped, PATH-i has been entered Which ONE of the following describes (1) a condition/parameter that would require the operator to continue taking actions lAW AOP-0i2, AND (2) when will it be appropriate to take those actions?
A. (I) Condenser Pit High Level alarm annunciates (2) Continue performing the actions of AOP-0i2 only after EPP-004 is exited. B (1) Condenser Pit High Level alarm annunciates (2) Continue performing the actions of AOP-012 during the performance EPP-004 as time allows C. (1) Continuous running of both Industrial Waste Sump pumps is observed (2) Continue performing the actions of AOP-01 2 only after EPP-004 is exited D. (1) Continuous running of both Industrial Waste Sump pumps is observed (2) Continue performing the actions of AOP-012 during the performance EPP-004 as time allows 203
2011 HP SRO NRC Written Exam Feedback Plausibility and Answer Analysis Per AOP-012, section 3.0, step 13, if a Condenser pit high level alarm is received in conjunction with either a known expansion joint failure or a Cooling Tower low level alarm, a complete failure of a Circulating Water expansion joint is indicated. AOP-012 will then direct a Reactor trip and transition to EOP-PATH-1, with follow up action to secure all Circulating Water pumps and Normal Service water pumps. Per EOP Users Guide, while implementing EOPs, it may be necessaiy to implement actions identified in the AOPs. This is acceptable assuming that referencing an AOP does not delay accident mitigation as outlined in the EOPs. Particular attention should be given to actions that will protect major plant equipment and/or enhance plant control. The option does not delay accident mitigation and these substeps do protect major plant equipment. A. Incorrect. Part I is correct. Part 2 is plausible since the last step of EOP-EPP-004 is to maintain stable plant conditions and perform the appropriate plant procedures. The candidate may assume that at this time AOP procedures should be performed since EOP procedure proformance has ended. B. Correct. C. Incorrect. Part I is plausible since flooding in other areas of the turbine bldg and if the condenser pit overflowed would cause both industrial waste sump pumps to run continously. Part 2 is plausible since the last step of EOP-EPP-004 is to maintain stable plant conditions and perform the appropriate plant procedures. The candidate may assume that at this time AOP procedures should be performed since EOP procedure proformance has ended. D. Incorrect.

2011 HNP SRO- NRC Wrkteri Exam Feedback Plausibility and Answer Analysis WOG step description for reason to check for Containment sump activity level during a response to Containment Flooding states that the water should be sampled in order to provide information concerning the possible transfer of Containment sump water to plant storage tanks outside the Containment. The disposition of this water outside the Containment will depend in large part on the level of radioactiivty in the water. The EOP Users Guide says that once an FRP is entered due to a RED or ORANGE condition, that FRP is performed to completion, unless preempted by some higher priority condition. It is expected that the actions in the FRP will clear the RED or ORANGE condition before all the operator actions are complete. However, the FRPs should be performed to the point of the defined transition to a specific EOP (or SAMG) or to the procedure and step in effect. A. Incorrect. The first part is plausible because cnmt fan coolers are isolated based on conditions in FRP-J. I and ESW is a non-borated water source so the sump sample could help distinguish the source of water. The second part is correct. B. Incorrect. The first part is plausible because cnmt fan coolers are isolated based on conditions in FRP-J. I and ESW is a non-borated water source so the sump sample could help distinguish the source of water. The second part is plausible since operation of components in cnmt could be challenged by leaving FRP-J.2 without lowering containment sump level. C. Incorrect. The first part is correct. The second part is plausible since operation of components in cnmt could be challenged by leaving FRP-J.2 without lowering containment sump level. D. Correct. 207

20-I1HNPSRONRCWr1ttenExarn Feedback Plausibility and Answer Analysis Given the current plant conditions, there will be no AFW source other than the TDAFW pump. TDAFW steam supply valves will be addressed in multiple procedures for this scenario. EOP-EPP-014 will be entered from PATH-i, based on lowering SG pressure. EOP-EPP-14 will transition to EOP-EPP-015 based on all SG pressures going down. The first step in EOP-EPP-015 directs foldouts to be implemented, at which time the foldout for PA TH-2 transition will apply based on high radiation. PA TH-2 directs isolating IMS-70 as long as another supply is available. A. Incorrect Plausible as the TDAFW pump is the only source of AFW available. The second part is plausible because EPP-014 will isolate a faulted SG by shutting the faulted SG steam supply valve to the TDAFW pump. With the conditions given in this question this step would not be performed because the procedure will be exited prior to reaching the actions to close the valve. In step 3 of EPP-014 the check forANY SG not faulted is performed. Since one B SG safety valve is stuck open and ALL MSIVs will not close ALL SGs are faulted and all SG pressures would be decreasing. Therefore a transition to EPP-015 would be made prior to reaching step 5 to isolate 1MS-70. B. Incorrect First part is correct. The second part is plausible because EPP-014 will isolate a faulted SG by shutting the faulted SG steam supply valve to the TDAFW pump. With the conditions given in this question this step would not be performed because the procedure will be exited prior to reaching the actions to close the valve. In step 3 of EPP-014 the check for ANY SG not faulted is performed. Since one B SG safety valve is stuck open and ALL MSIVs will not close ALL SGs are faulted and all SG pressures would be decreasing.

Given the following plant conditions:
- A Site Area Emergency has been declared - The Technical Support Center has NOT yet been staffed - The Shift Manager is acting as the Site Emergency Coordinator Main Control Room (SEC-MCR) and has directed a team of two Maintenance personnel to work in a radiologically hazardous area of the RAB - The Radiological Control Director (RCD) is standing by to assist - Each person performing the work is expected to receive 5500 mrem TEDE for this entry Which ONE of the following correctly describes the limitation basis for the type of entry AND the position that must approve each team member to receive the expected dose lAW PEP-330, Radiological Consequences?
Limitation Basis Position A. Protection of large populations ONLY SEC-MCR B. Protection of large populations ONLY RCD C Protect valuable property or large populations SEC-MCR D. Protect valuable property or large populations RCD 244
2011 HNP- SRO NRC Written xam Feedback Plausibility and Answer Analysis PEP-330 Attachment I identifies that exposures up to 10 REM are allowed to protect valuable property. PEP-230, SEC-MCR Attachment I step 29 states the following: Authorize Progress Energy emergency worker exposures > 5 Rem TEDE or entry into fields > 25 Rem/Hr per PEP-330, Att. 1, as necessary. A. Incorrect- The first part is incorrect. PEP-330 Attachment I identifies that emergency exposure limits of 25 REM are in place to protect large populations or life saving activities. Plausible since during maintenance activities, exposure can be received resulting in a dose exceeding 5 REM, and misundertsanding of basis could occur since the intent of the emergency plans is to protect the health and safety of the public. The second part is correct since PEP-230, Attachment I step 29 states the following: Authorize Progress Energy emergency worker exposures
> 5 Rem TEDE or entry into fields > 25 Rem/Hr per PEP-330, Att. 1, as necessary.
B. Incorrect- The first part is incorrect (See A). The second part is incorrect. Plausible since the RCD evaluates the need for and coordinates with the SEC -TSC authorization of the allowance of onsite emergency worker exposures > 5 Rem TEDE or entry into fields > 25 Rem/Hr per Attachment 8 of PEP-240.

Remain in AOP-036 Rack out the breaker for the A Group of PZR Backup Heaters D Remain in AOP-036 OPEN the feeder breaker to Bus IAI 247
2(H1 HNP SRQNRC Written Exam Feedback Plausibility and Answer Analysis The Fire in the A Transfer Panel is considered a MAJOR fire as prescribed in the AOP-036 Basis Document. A MAJOR fire requires the use of AOP-036 to perform the plant shutdown. FPP-OO2 directs deenergizing the affected bus when components are obseived to spuriously operate. A Incorrect. Incorrect AOP-036 Action, this is plausible though as only one train of equipment is on fire and the individual may believe a normal shutdown using normal procedures can be performed using the other train. Correct FPP-002 Action. B Incorrect. Incorrect AOP-036 Action, this is plausible though as only one train of equipment is on fire and the individual may believe a normal shutdown using normal procedures can be performed using the other train. Incorrect FPP-002 Action but racking out the breaker will deenergize the affected component and alleviate the effect of the heaters cycling on and off C Incorrect. Correct AOP-036 Action (remain in AOP-036). Incorrect FPP-002 Action but racking out the breaker will deenergize the affected component and alleviate the effect of the heaters cycling on and off D Correct.

The tern safety related is used rather than safe shutdown related for ease of operator recognition to minimize delay in procedure implementation when necessary. A MAJOR fire in a safe shutdown area is defined as a fire affecting more than one safety related component. This includes the following: 248
2011 HNP SRO NRC Written Exam Major termination cabinets or junction boxes Cable trays Transfer panels Buses involving more than one cubicle Control panels affecting more than one safety related switch Tier/Group: T3 SRO justification: This is a branching step in AOP-036 (step 2). This step determines whether the crew will remain in AOP-036 and perform an emergency plant shutdown due to the fire or return to the procedure and step in effect. To come to the correct answer requires knowledge of the Note prior to step 2 and knowledge of the definition of MAJOR fire contained in the AOP-036-BD. No indications or effects are given on the other train, so the individual must use this knowledge to come to the correct answer otherwise they may believe no shutdown is required or that a normal shutdown can be performed using B Train. 249

2014 KNP SRNRC Written Exam 100. 2011 NRC SRO 025/BANKJFUNDAMENTAL////EARLY SUBMITTAL/G 2.4.18/ Given the following plant conditions:
- A Reactor trip has occurred due to a loss of MEW - FRP-H.1, Response to Loss of Secondary Heat Sink, is being implemented - The RCS is in a bleed and feed condition - RCS Tavg is 570°F and stable - The operators have restored a feedwater source and are preparing to feed the SGs which are dry - The CRS directs the operator to establish feed water to only one SG Which ONE of the following describes the reason for feeding only one SG under these conditions?
A. To prevent a rapid cooldown of the RCS that could lead to a pressurized thermal shock condition. B. To demonstrate the reliability of the FW source before filling all of the SGs. C. To determine if one SG is capable of maintaining adequate heat sink so that RCS bleed and feed can be terminated. D To ensure that if a SG failure occurs due to excessive thermal stresses, the failure is isolated to one SG. 251
2011 HNP SRQ- NR Written Exam Feedback Plausibility and Answer Analysis WOG background for FRP-H. 1 section 2.4 Feeding a Diy Steam Generator Since the heat removal capability of one steam generator is always greater than decay heaI, it is advisable to reestablish feedwater to only one steam generator regardless of the size of the plant or number of loops. Thus, if a failure in an SG occurs due to excessive thermal stresses, the failure is isolated to one steam generator. A. Incorrect. Plausible since feeding AFW will cause a cooldown but cooldown rate depends on amount of feedwater, not distribution between generators. B. Incorrect. Plausible since candidate could believe that FW would need to be reliable since a method of heat removal is taking place using bleed and feed but a demonstration of reliability is not required in FRP-H. I C. Incorrect. Plausible if candiate believes that as soon as FW is established to one SG bleed and feed can be terminated but bleed and feed will not be terminated based on having flow to the SG. Termination of bleed and feed is after an adequate secondary heat sink is verified by having SG narrow range level> 25% [40% adverse]. D. Correct. 252
