Beaver Valley Unit 1 NRC Written Exam (1LOTS) 1. Given the following plant conditions and seqUl:mce of events:

The plant is operating at 100% power.

1 MSP-1.05-1, "Reactor Protection System Train B Test" is being performed.

Reactor Trip Bypass Breaker (BYB) has been closed. * "B" Train SSPS input error inhibit switch is in the INHIBIT position.

A turbine trip occurs.

All systems function as designed.

Which ONE of the following breakers will receive a trip signal? RTA -(Reactor Trip Breaker RTB -(Reactor Trip Breaker BYA -(Reactor Trip Bypass Breaker BYB -(Reactor Trip Bypass Breaker A. RTAONLY. B. RTA and BYB. C. RTB and BY A. D. RTB and BYB. Answer: B Explanation/Justification: Incorrect.

Train A RTB will open, however, it is not the only breaker which will open. BYB will also open. Correct. Since reactor power is > P-9 (49%), a turbine trip will result in a reactor trip signal to RPS. With Train B SSPS input error inhibit switch in INHIBIT, upon reactor trip, the Train A reactor protection system de-energizes the Train A Reactor trip Breaker and the Train B Bypass breaker UV ceils. BYB is closed to allow testing on the "B" Train. Incorrect.

Train B ATB will not open due to Train B SSPS input error inhibit switch in the INHIBIT position.

BYA will not open. Incorrect.

Train B RTB will not open due to Train B SSPS input error inhibit switch in the INHIBIT position.

BYB will open.

Beaver Valley Unit 1 NRC Written Exam (1LOT8) 2. Given the following plant conditions: Reactor Power is 85%, steady state, all systems in NSA. Pressurizer (PRZR) pressure control is in its normal configuration. Pressurizer Relief Valve (PCV-1 RC-45SC) inadvertantly lifts and does NOT fully reseat.

A4-11, "PRESSURIZER CONTROL PHESSURE LOW", annunciates. PRZR Pressure is 2170 psig and slowly lowering.

How will the PRZR Spray Valves (PCV-1 RC-455A and PCV-1 RC-455B) and PRZR PORV Block Valves (MOV-1 RC-535, 536, 537) respond to these plant conditions, with no operator action? PRZR Spray Valves _ (1) _. PRZR PORV Block Valves _ (2) _. A. (1) remain open remain open B. (1) close (2) remain open C. (1) remain open (2) close D. (1) close (2) close Answer: B Explanation/Justification: Incorrect.

Spray Valves auto close on lowering PRZR pressure versus remain open. If candidate does not understand PZR Pressure scheme, they may have a misconception on how this control works. Correct that block valves will remain open (NSA Correct. A lowering PRZR pressure due to the vapor space leak caused by PORV leakage results in a low pressure alarm when PRZR pressure drops to 2185 psig. This lowering demand signal closes spray valves as shown on technical references.

The PRZR PORV Block valves will remain open due to control switches NSA Normal until the operator takes action to close these valves. Incorrect.

PRZR Spray Valves close on lowering PRZR pressure versus remain open. Plausible that PRZR Block Valves will automatically close when 213 PRZR pressures channels are @ 2185 psig if the control switch was in AUTO versus OPEN since this is the Unit 2 design. Incorrect.

Correct Spray Valve Position.

119. Given a specific plant condition, predict the response of the pressurizer and pressure relief system control room indication and control loops, including all automatic functions and changes in equipment status, for either a change in plant condition or for an off normal condition: (Excessive Primary Plant Leakage, RCS voiding, process instrument failure)

Beaver Valley Unit 1 NRC Written Exam (1LOT8) 3. Given the following plant conditions:

A. B. C. D. Unit 1 experienced a Small Break Loss of Coolant Accident (SBLOCA). A manual Reactor Trip and Safety Injection was initiated. RCS pressure is 785 psig and stable. The hottest Loop THot indication is 471 Of and stable. The average of the FIVE hottest CET's is 483 Of and stable. Total Feed Flow is 600 gpm and stable. Pressurizer Level is 15% and stable. Containment Pressure is 5.5 psig and stable. Operators are determining whether conditions are present to allow a transition to ES-1.1 , "SI Termination", from E-O, "Reactor Trip or Safety Injection".

The Unit Supervisor asks the Reactor Operator to determine RCS subcooling using Steam Tables. Which of the following identifies current RCS subcooling.

and whether a transition to ES-1.1 is appropriate? (Reference Provided)

Subcooling is approximately

_ (1) _. and the transition to ES-1.1 (2) _ be made. (1) 35°F (2) shall (1) 470f (2) shall (1) 350f (2) shall NOT (1) 47°F (2) shall NOT Answer: C Explanation/Justification: Incorrect.

Correct subcooling margin @ 3S'F. Incorrect that transition criteria is met. (refer to correct answer explanation) Incorrect.

If the candidate uses Thot as opposed to CET to calculate subcooling, it will come out to 47'F which makes this a plausible however, the transition criteria is still not met based on PRZR level (refer to correct answer Correct. 785 psig equals 800 psia. Saturation temperature for 800 psia is 518.21*F lAW Steam Tables. Subcooling is 3S.21'F. The subcooling criteria>

54'F is NOT met. Since subcooling criteria is NOT met, the RNO requires the use of Attachment 6-A which is provided.

At 785 psig, the 35 F would be met based on adverse criteria, however, the required 38% PRZR level is not met since adverse containment numbers apply due to containment pressure>

5 psig. Based on these numbers, transition critElfia is NOT met and a transition to ES-1.1 shall NOT occur. It is reasonable that the candidate know SI termination criteria from memory, so therefore this criteria is NOT provided.

KIA is met because subcooling and heat sink are the tie between a SBLOCA and the S/Gs and also relate to SI termination criteria. Incorrect.

Incorrect subcooling value. Correct that transition shall not be made. (refer to correct answer explanation).

Beaver Valley Unit 1 NRC Written Exam (1LOT8) 5. Given the following plant conditions: The Unit was operating at 60% when all charging flow was lost. The Control Room Team entered AOP 1 .7.1 , "Loss of Charging Or Letdown". Letdown has been isolated and charging restoration is being investigated. The Reactor Operator reports Pressurizer (PRZR) level is lowering at a rate of 1 % every five (5) minutes. PRZR Level was 4% below reference when letdown was isolated.

If charging flow is NOT restored, which ONE of the following is the LONGEST time that PRZR heater operation can be maintained?

A. 40 minutes B. 85 minutes C. 125 minutes D. 145 minutes Answer:C Explanation/Justification: Incorrect.

Value reflects 22% -14% = (8%) (5) = 40 minutes. Incorrect initial level. Incorrect.

Value reflects 39% -22% = (17) (5) = 85 minutes Incorrect final level Correct. At 60% power, PRZR Level is 60% of full range (0% power 547 F = 22% PRZR Levell 1 00/0 power 578 F = 57 % PRZR Level) Therefore at 60% PRZR level =43%. The stem of the question indicates PRZR Level was 4% less than reference which =39%. PRZR Level cutout automatically occurs when PRZR level reaches 14%. Therefore with level lowering 1 % every 5 minutes, it will take 125 minutes to reach 14%. 125 minutes is the longest time that PRZR heater operation can be maintained based on these plant conditions.

All distractors are plausible based on misconceptions or common errors. Incorrect.

Value reflects 43% -14% = (29%) (5) =145 minutes. Did not subtract 4% below reference level.

(1) CCR Leak downstream of 1A RCP Thermal Barrier (2) inlet and outlet containment isolation valves for 1 A RCP will CLOSE. Answer: B Explanation/Justification: Incorrect.

Plausible that 1A RCP thermal barrier could be leaking based on increasing FI-1CC-107A flow, however, the candidate must differentiate out leakage from the system versus in leakage based on CCR Surge Tank level change. Correct that a high flow condition at 58 gpm will close the 1 A RCP thermal barrier outlet valve. Correct. Increasing flow on FI-1CC-107A combined with a dropping CCA Surge Tank level is indicative of a leak downstream of 1A RCP thermal barrier. TV-1CC-107A will auto close when CCR Flow as sensed by FT-1 CC-107A increases to 58 GPM. Dropping 8urge Tank level is an entry condition for Loss of CCR AOP. The KIA is met because the candidate must have knowledge that Loss of CCR AOP entry conditions have been met and they must be able to monitor the impact on an Rep which is a CCR heat load monitored in the control room. They must have specific knowledge of the operational impact based on stated parameters in the stem of the question. Incorrect.

Incorrect spray valve response.

Plausible if candidate does nDt recognize the impact of the Master pressure Controlier failure. heaters will remain energized.

Plausible if the candidate believes PRZFlievel drops to 14% which cuts off PRZR heaters by Incorrect.

Incorrect spray valve response.

Correct PRZR Backup Heater response. Incorrect.

Correct spray valve response.

PRZR heaters will remain energized.

Plausible because PRZR heaters are designed to turn off increasing PRZR Correct. A load rejection results in an increase in RCS temperature. (PI.ant will not trip due to reactor power level) The Tavg increase will cause an expansion of water into the PRZR (Insurge) compressing the vapor space which in turn will increase PRZR pressure.

On increasing PRZR pressure, the Master Pressurizer Control System is designed to open the Spray Valves to lower PRZR pressure back to NOP (2235 psig). However, since the Master Pressure Controller has failed as is, it will not respond to the changing system parameters and therefore will not reposition Spray Valves open. Backup PRZR heaters 2A & 2B will remain energized because they are energized on and the master pressure controller has failed at a setpoint which will not cause them to turn off regardless of what happens to PRZR pressure follOwing the transient.

What is the reason for this isolation? To prevent water hammer and potential seal injection line failure. To prevent potential RCP seal damage when a charging pump is restarted. To reduce the possibility of radioactive release to the. Auxiliary Building. To prevent steam formation in Component Cooling System due to overheating in the thermal barrier. Answer: B Explanation/Justification: Incorrect.

Plausible that water hammer and seal injection line failure could occur, however, not the background document reason for isolation. Correct. According to ECA-O.O background document, isolating RCP seal injection lines prepare the plant for recovery while protecting the RCPs from seal and shaft damage that may occur when a charging pump is started as part of recovery.

With RCP seal injection lines isolated, a charging pump can be started in the normal charging mode without concern for cold seal injection flow thermally shocking the RCPs. Incorrect.

Beaver Valley Unit 1 NRC Written Exam (lLOT8) 16. Given the following plant conditions and sequence of events:

The Unit is operating at 20% power. * "B" Main Feedwater Pump is running.

No. 1 Emergency Diesel Generator (EDG) is on clearance.

A normal plant shutdown is in progress due to inoperability of No.1 EDG. * "B" RPRW pump was just taken to Pull-to-Lock due to excessive seal leakage reported in the intake structure cubicle. An "A" 4KV Bus electrical fault occurred resulting in the following breakers tripping OPEN: o Main Generator Exciter Breaker o Both Main Generator Output Breakers o 4KV Bus "A" Feeder Breakers from USST and SSST. Based on these plant conditions, which of the following procedures have valid required entry conditions within three (3) minutes after the Bus "A" fault occurred? (assume all systems function as designed)

1. E-O, "Reactor Trip or Safety Injection".

2. AOP 1.26.1, "Turbine and Generator Trip". 3. AOP 1.36.2, "Loss of 4KV Emergency Bus". 4. AOP 1.30.2, "River Water/Normal Intake Structure Loss". A. 1 ONLY. B. 3 &4 ONLY. C. 1, 2, 3, &4. D. 2,3, & 4 ONLY. Answer: D Explanation/Justification: Incorrect.

The candidate must recognize that a Loss of the "A" RCP (Bus 1A) will NOT result in a reactor trip since the reactor is < P-8 (30%). Also the stem of the question notes that "S" MFP is running to dispel a challenge that a loss of main feedwater occurred due to a loss of the "B" MFP. This is a plausible distractor and would be a correct choice if the reactor were:> 30% power. A reactor trip is NOT required for these conditions since none has occurred and no valid entry conditions have been met. Incorrect.

Both choices are correct. however. AOP 1.26.1 will also have valid entry conditions (refer to correct answer). Plausible because candidate may either not recognize a turbine trip occurred or may think it is not applicable since we are < p-g (49% reactor Incorrect.

Incorrect that E-O is required. (refer to correct answer and A distractor explanations for why other choices are correct). Correct. A Loss of 1 AE Bus will occur with No.1 EDG on clearance and a loss of offsite power source available to 4160 Bus A. With no power to the AE Bus entry conditions will be met for AOP 1.36.2. Since a turbine trip will occur due the nature of the electrical fault which opened both main generator breakers and exciter output breakers entry conditions for AOP 1.26.1 are met. Since the "B" RW pump was placed in PTL and a Loss of the AE Bus occurred, there is no power to the "A" Train River Water Pump which results in a Loss of River (Service)

(1) increase (2) 57.5 Hz B. (1) increase (2) 58.5 Hz C. (1) be unaffected (2) 57.5 Hz D. (1) be unaffected (2) 58.5 Hz Answer: A Explanation/Justification: Correct. Step 6 of AOP AOP Y2.35.1 requires reactor power maintained at <1= 100% and directs a power reduction if power> 100%. As grid frequency/voltage drops, the power requirement increases which will result in increasing reactor power. An automatic reactor trip will occur if 2/3 RCP 4KV Bus frequencies drop to 57.5 Hz. With the Main Turbine in 1 st Stage IN, as grid frequency drops, the increased steam demand will result in a drop in 1st stage pressure which will open governor valves to compensate for the load increase.

These indications are indicative of L T -1 RC-459 failed in the as is position. Incorrect.

These indications are indicative of plausible candidate misconceptions related to actual vs. programmed PRZR level and Correct. If the PRZR Level controller fails as is and a load reduction occurred, then the input to FCV-1CH-122 will not change. Therefore 122 indicated flow will remain the same. Since a power reduction results in a Tavg decrease, then Program Level as indicated on LR-RC459 will drop to correlate with the PRZR Level Program. Program level is impacted by power reduction not the failure of LC-459G. Incorrect.

Given the following plant conditions: The Unit is operating at 70% power when air leakage into the condenser resulted in a rising condenser backpressure. The Control Room Team is performing actions of AOP-1.26.2, "Loss of Condenser Vacuum". Concurrently, a load reduction is initiated at a rate of 5%/min in accordance with 1.51.1, "Unplanned Power Reduction". Five minutes after the load reduction was commenced, condenser backpressure has risen to 5.5 IN HG-ABS. Ten minutes after the load reduction was commenced, condenser backpressure has risen to 6 IN HG-ABS and continues to slowly rise. Which ONE of the following will be the REQUIRED action according to AOP-1.26.2, "Loss of Condenser Vacuum"? (Reference Provided) Immediately trip the reactor and go to E-O, "Reactor Trip or Safety Injection". Trip the reactor if condenser vacuum approaches C-9 setpoint and go to E-O, "Reactor Trip or Safety Injection". Immediately trip the turbine and go to AOP 1.26.1, "Turbine and Generator Trip". Trip the turbine if condenser vacuum approaches C-9 setpoint and go to AOP 1.26.1, "Turbine and Generator Trip". Answer: C Explanation/Justification: Incorrect.

This is a correct action if condenser vacuum remains >5.5 IN HG-ABS for more than five minutes and reactor power is > P-9, however, reactor power is < P-9 (490/0). After five minutes of load reduction reactor power is 45%. Incorrect.

This is a correct action referenced in AOP 1.26.2 if reactor power is > 10"/0, however, C-9 (lOIN HG-ABS) is not being approached at 6 in hg-abs and other trip criteria have been exceeded. Correct. According to AOP-l.2S.2, a turbine trip and entry into AOP 1.26.1 is required if reactor power is < P-9 (49%) and backpressure is > 5.5 IN HG-ABS for > 5 minutes and cannot be restored.

C. RIS-1CH-101A, "Reactor Coolant Letdown High Range Monitor".

D. RIS-1 RM-219A, "Containment High Range An3a Monitor".

Answer: D Explanation/Justification: Incorrect.

RM*1 RM*201 functions to provide local and control room indication of reactor containment area activity.

RM*1 RM*201 is an Ion Chamber detector and is more accurate at the mid to high radiation levels. The log scale for this meter is .1 to 1 E7 mr/hr. This falls short of the 1 E5 r/hr dose necessary to detect adverse containment conditions due to the limitations of its detector.

PlaUSible because it is used in AOP 1.S.S. Incorrect.

RM*1 RM*204 functions to provide local and control room indiGation of increased radiation levels during accident conditions, RM*1 RM* 204 is a Geiger*Muelier detector which functions to detect gamma radiation.

The log scale for this meter is .1 to 1 E4 mr/hr. This falls short of the 1 ES rlhr dose necessary to detect adverse containment conditions due to the limitations of its detector.

Correct that asphyxiation is a major concern. Incorrect that halon is used in this space (refer to COfrect answer). Incorrect.

Water is not used in the East Cable Vault as part of any autornatic suppression fire fighting systems and therefore flooding is not a major concern. Correct. The candidate must know that C02 is the fire fighting agent uSl3d in the East Cable Vault to automatically distinguish fires. Water or Halon are NOT used in this area. The operational implications of a serious fire in the East Cable Vault is that CO2 is a major concern when entering this space due to the safety hazards it may cause (ie: cardiac arrest or nervous system effects). Incorrect.

Water is not used in the East Cable Vault as part of any autornatic suppression fire fighting systems and therefore flooding is not a major concern.

Beaver Valley Unit 1 NRC Written Exam (1LOTS) 23. Given the following plant conditions: A major uncontrolled fire in the Control Room has resulted in control room evacuation. The Control Room Team is implementing 10M-S6C, "Alternate Safe Shutdown from Outside the Control Room". What is the reason for system alignment and maintaining Pressurizer Level during cooldown to Cold Shutdown according to 10M-S6C series procedures?

System alignment to maintain Pressurizer Level between 20% -70% will be to _____ A. maintain RCS inventory ONLY. B. maintain RCS inventory AND shutdown margin. C. ensure auto letdown isolation does not occur ONLY. D. ensure auto letdown isolation does not occur AND to maintain shutdown margin. Answer: B Explanation/Justification: Incorrect.

It is plausible and partially correct that PRZR level is maintained to maintain RCS inventory.

SID margin is also maintained by using a charging pump taking suction from the RWST during these plant conditions lAW 10M-S6GA.B. Correct. A charging pump is used for both maintaining RCS inventory as well as providing borated water from the RWST after realignment to help maintain adequate SID margin. PRZR heaters are not related to maintaining PRZR level but rather RCS pressure control so therefore are not included as part of answering the KIA. According to 10M*S6CA.B, PRZR Level is maintained 20% to 70%. This is a higher cognitive question because the intent and methodology of 10M-56CA.AlB must be known and is specific to evaluating this set of plant conditions. Incorrect.

Plausible that PRZR is maintained>

14% to ensure UD isolation does not occur, however, the overall purpose of this procedure is perform safe shutdown without the letdown system. Letdown isolation is time critical and manually occurs prior to control room evacuation.

Procedurally it is allowable to initiate head vent letdown if required which has no auto letdown isolation features. Incorrect.

Incorrect that PRZR level is maintained to ensure auto UD iscllation does not o(:cur.

A Main Steam Line Break occurred inside containment. All systems functioned as designed. The Control Room Team is now performing actions of FR-P.1, "Response to Imminent Pressurized Thermal Shock Condition". They have determined an Res Temperature Soak is required.

Which ONE of the following component/system actions is allowed to be performed during the soak period while FR-P.1 is being implemented?

A. Energize Pressurizer Heaters. B. Place Auxiliary Spray in service. C. Place RHR in service with flow through MOV-1 RH-758. D. Raise NR S/G water levels to 70% and secure AFW pumps. Answer: B Explanation/Justification: Incorrect.

Energizing PRZR heaters will raise RCS pressure which is not allowed during soak. Correct. During RCS soak, FR*P.1 directs that cooldown in the RCS will not occur until temperature has been stable for 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . RCS pressure is not to be raised during this period of time. Actions of other procedures may be performed provided that actions do not cooldown or raise pressure until the soak has been completed.

Placing Aux Spray in service will lower RCS pressure which is allowable. Incorrect.

Placing RHR in service and allowing flow through MOV-1 RH-758 will result in an ReS cooldown which is not allowed during soak. Incorrect.

Beaver Valley Unit 1 NRC Written Exam (1LOTS) 25. Given the following plant conditions: The Control Room Team has just transitioned to ES-0.3. "Natural Circulation Cooldown With Steam Void in Vessel (With RVLlS)" due to increased cooldown rate. Pressurizer and Steamline Safety Injection (SI) signals are blocked. RCS temperature is 500 Of. Letdown is in service. Due to mis-operation of PRZR heaters, RCS pressure has risen to 2025 psig. Which ONE of the following is the minimum required action(s) to restore PRZR pressure to 1800 psig? Use _ (1) _ PRZR Spray to reduce PRZR pressure to (2) A. (1) Normal (2) 1800 psig B. (1) Auxiliary (2) 1800 psig C. (1) Normal 1950 psig. block PRZR &51 signals, then reduce pressure to 1800 psig D. (1) Auxiliary 1950 psig, block PRZR & 51 signals, then reduce pressure to 1800 psig Answer: D Explanation/Justification: Incorrect.

Normal spray is unavailable since RCPs are secured in ES-0.3. SI would initiate if PRZR pressure were reduced directly to 1800 psig. Incorrect.

Correct that auxiliary spray is used to depressurize.

SI would initiate if PRZR pressure were reduced directly to 1800 psig. Incorrect.

Normal spray is unavailable since RCPs are secured in ES-0.3. The reblocking sequence is correct. Correct. SI is blocked in ES-0.2 and a cooldown rate of < 25 F/hr is established in ES-0.2. Since the cooldown rate is exceeded, the potential for head void formation exists and transition to ES-0.3 is required.

The caution from ES-0.2 still applies upon transition to ES-0.3. The SI system is designed to automatically unblock if PRZR pressure increases above 2000 psig (P-11). A subsequent drop in RCS pressure below the SI setpoint 1845 psig before manually reblocking the SI signal will result in an SI which is undesirable in ES-0.3.

While monitoring Critical Safety Functions, containment pressure is currently 15 psig. NO Quench Spray Pumps are operating. Containment Sump Level has been slowly rising and is currently 65 inches. Based on these conditions, which ONE of the following identifies the status of the Containment Critical Safety Function (CSF) Status Tree? A RED path condition CURRENTLY (1) __exist for __ (2) __. A. (1) does (2) containment pressure ONLY. B. (1) does (2) containment sump level ONLY. C. (1) does (2) containment pressure AND containment sump level. D. (1) does NOT (2) either containment pressure OR containment sump level. Answer: D ExplanationfJustification: Incorrect.

An orange versus red path exist for containment pressure based on no quench spray pumps running and containment pressure > psig. It is plausible that a candidate may select this choice based on exceeding 45 psig which is a red path condition, however, the CSFST only if pressure is < 45 Incorrect.

Incorrect that a red path exists. Containment sump level would need to be> 81 inches and this would be an orange path condition. Incorrect.

No red path condition exists for either a containment high pressure or level condition.

Plausible if candidate does not determine plant conditions or know from memory CSFST Red paths which are required RO knowledge at Correct. According to Containment CSFST (F-O.5), no red path condition exists for either a containment high pressure or level Validators had misconceptions that the Red path is not applicable when RCS pressure is < 45 psig even though it had previously exceeded threshold.

(1) Safety Injection and Component Cooling Water (2) verify containment isolation and heat removal. C. (1) River Water (2) isolate the source of leakage. D. (1) River Water and Component Cooling Water (2) verify containment isolation and heat removal. Answer: C Explanation/Justification: Incorrect.

High containment sump water level greater than the design flood level provides an indication that water volumes other than represented by the emergency stored water sources have been introduced into the containment sump (ie: RWST, SI Accumulators and Correct desired outcome (refer to correct answer Incorrect.

Incorrect sources. Incorrect desired operating outcome, although plausible since this is the correct outcome of FR-Z.1 versus FR-Z.2. Correct. Fire protection or River Water penetrate containment and could provide large flow rates to components inside the containment and major break or leak in one of those lines could introduce large quantities of water into the sump.

With no operator action, which ONE of the following describes the effect on the PRZR pressure control system, ONE (1) minute following the failure? A. TWO PRZR PORVs will be OPEN. B. ONE PRZR PORV and BOTH PRZR Spray Valves will be OPEN. C. PRZR B/U heaters will be ON and BOTH PRZR Spray Valves will be CLOSED. D. PRZR B/U heaters and BOTH PRZR Spray Valves will remain in their NSA positions.

Answer: C Explanation/Justification: Incorrect.

These indications are indicative of PT-1 RC-445 failing in the high direction.

Also, Actual PRZR pressure will rise due to PRZR heaters being energized without spray flow. With no operator action it is plausible that PORV's will open however, they will not open one minute following this failure. Incorrect.

These indications are indicative of PT-1 RC-444 failing in the high direction.

Atthough one PORV will not lift within one minute, with operator action, one PORV will eventually lift to relieve PRZR pressure.

It is not correct that the spray valves will Correct. The result of PT-1 RC-444 failing low is BOTH PRZR spray valves will be closed and PRZR heaters will be ON. Incorrect.

These indications are indicative of PT-l RC-445 failing in the low direction as opposed to PT-1 RC-444.

Answer: C Explanation/Justification: Incorrect.

Part 1 is correct. Part 2 is incorrect. (refer to correct answer explanation). Incorrect.

Part 1 incorrect, Plausible if the candidate does not know the auto start setpoin! (recently changed at BVPS such that they used to start after a time delay shortly after CIB actuation).

Part 2 is incorrect. Correct. With no operator action, containment pressure will continue to rise due to energy from LOCA being added to the containment with no heat sink. Recirc Spray pumps will not start until RWST level drops to 2'1.5 feet. Management expectations (operator fundamentals) lAW OP-1002 are that if an ESF component did not auto start as designed a manual attempt to start the component will be made by the operator.

This action does not require SRO approval prior to attempting a start of the CIS pumps after immediate operator actions are completed at Step 4 E-O. Incorrect.

Incorrect header. Plausible if the candidate believes NSA is to the "S" header or believes the impact of 1 FW*P-3A realignment of 1 FW-P-2 to the "S" Correct. A loss of offsite power coincident with a turbine trip results in a reactor trip and subsequent loss of both MFW pumps. The EDGs are designed to start on a loss of power to AE and DF bus which will power both electric AFW pumps. In the stated conditions, with an overcurrent condition on the DF bus, 1 FW-P-3B will not have power. Since 1 FW-P-:3A is already OOS, only 1 FW-P-2 (Turbine Driven AFW pump) will start to provide 700 gpm AFW flow. The AFW system is designed to feed all three S/G based on NSA alignment requirements.

NSA has 1FW-P-2 aligned to the "An Header. Incorrect.

Correct capacity.

If the candidate does not know the capacities or understand the impact based on initial plant conditions, then it plausible that AFW flow would be provided through the "A" header by 1 FW-P-2 and the "8" header by 1 FW-3B.

Incorrect system design. (refer to correct answer explanation) Incorrect.

Incorrect position.

Incorrect system design. (refer to correct answer explanation) Correct. FCV-1 FW-1 03A is designed to open upon AFW pump start to ensure sufficient recirc flow for pump COOling. The recirc valve senses suction flow <<145 gpm) and opens to ensure:> 145 gpm is flowing through the pump. In NSA the discharge valve is not shut, The recirc valve will open upon pump start and upon sensing sufficient suction flow will close. In this scenario the OST checks recirc valve operation by positioning FW-37 shut. Therefore there is no flowpath directly to the 8/Gs and the recirc valve will open to recirc water back to 1WT-TK-10, ensuring:>

145 recirc flow for pump cooling. All distractors are plausible if the candidate does not have knowledge of system design and plant configuration changes.

(2) accumulation of combustion and products in the exhaust system Answer: A Explanation/Justification: Correct. If frequency drops, the EDG will attempt to increase speed, which will pick up real load. TS Surveillance 3.8.1.3 bases states that the load band (2340 TO 2600 KW) which is more restrictive than the rated load in 1OST-36.1 (2850 KW) is to avoid routine overloading of the DG. Routine overloading may result in more frequent teardown inspections in accordance with vendor recommendations for DG OPERABILITY. Incorrect.

Correct EDG response.

Incorrect consequence.

The reason for significance of EDG loading is for ensuring loading is maintained

>50% for an hour when operating the EDG at low loads for extended periods of time. This limit is plausible in that it is more associated with operating the EDG at low loads and could be confused by the candidate. Incorrect.

Incorrect EDG response.

KVAR output will remain essentially constant if grid voltage is constant.

If it did change it would change in the opposite direction of KW. Significance of operating above rated limit is correct as explained above. D. Incorrect.

The plant is operating at 100% power with all systems NSA.

A Loss of 125VDC Bus 2 occurs.

The Control Room Team entered AOP 1.39.1B. "Loss of 125VDC Bus 2".

All systems function as designed and no operator action has occurred.

According to AOP 1.39.1 B, which ONE of the following describes the plant status? REACTOR TRIP A. WILL AUTO OCCUR B. WILL AUTO OCCUR C. WILL NOT AUTO OCCUR D. WILL NOT AUTO OCCUR Answer: B Explanation/Justification:

MAIN STEAMLINE ISOLATION CANNOT AUTO OCCUR CAN AUTO OCCUR CAN AUTO OCCUR CANNOT AUTO OCCUR Incorrect.

Incorrect that a MSLI cannot occur. Plausible because it is partially true that B train MSLI cannot occur since DC Bus 2 power is required however, A Train is still available for MSLI. (refer to correct answer explanation) Correct. Main Feedwater Regulating valves fail closed on a Loss of 125VDC Bus 2, so therefore at 100% power it will take about 30 seconds as validated on the simulator before a Lo-Lo S/G Water Level Reactor Trip automatically occurs. MSLI valves require DC power to close. Since only the B Train of power was lost, the A Train (DC Bus 1) is still available Sl) therefore MSLI can still auto occur if valid plant conditions warrant. Step 3 of AOP 1.39.1 B states to verify a reactor trip has occurred.

The candidate cannot challenge that a reactor trip will not auto occur regardless of time because it will occur. Incorrect.

Reactor trip will occur. Plausible if the candidate does not know the status of MFRVs. Correct that MSLI can occur. Also plausible if the candidate does not know the automatic actions of AOP 1.39.1 B. Incorrect.

Given a 125 VDC Distribution configuration, and without reference material, describe the 125 VDC distribution system control room response to the following malfunctions, including automatic functions and changes in equipment status: Loss of DC Bus Beaver Valley Unit 1 NRC Written Exam (1LOTS) 48. Given the following plant conditions and sequence of events: The Unit suffered a Loss of Off-Site Power. Both Emergency Diesel Generators (EDGs) are supplying emergency busses. Grid stability is confirmed and the Operations Manager has granted permission to return to the grid. The Control Room Team is performing 10M-36.4.Q, "Transferring Emergency Busses 1 AE and 1 OF From Emergency Feed to Normal Feed", beginning with Bus 1 AE. EDG 1-1 is synchronized to the grid and 4KV Bus 1 AE to 1 A ACB '1 E7 is closed. Upon breaker closure, the following annunciator sequence occurs: A8-107, "4160V EMERG BUS 1AE ACB-1 E7 OVERCURRENT TRIP" received. A8-106, "4160V EMERGENCY BUS 1 AE ACB-1 E7 AUTO TRIP" received. o ' A8-107, "4160V EMERG BUS 1AE ACB-1 E7 OVERCURRENT TRIP" clears. Which ONE of the following describes the impact on EDG 1-1? EDG 1-1 will ____cooling water available.

A. trip with B. trip without C. continue to run with D. continue to run without AnswerC Explanation/Justification: Incorrect.

EDG 1-1 does not trip but remains running. Plausible that the EDG would trip on an overcurrent condition, however, protection in scenario is provided by ACB 1 E7. Correct that cooling is still Incorrect.

EDG 1-1 does not trip but remains running. Plausible that the EDG would trip on an overcurrent condition, however, protection in scenario is provided by ACB 1 E7. Also incorrect that cooling water is not Correct. For the given conditions, EDG 1-1 is running paralleled to the grid. An overcurrent condition was caused by the closure of ACB1 E7 results in ACB 1 A 10 & 1 E7 automatically opening. Upon ACB-1 E7 opening, the overcurrent condition clears which is indicative of the being downstream of ACB 1 E7. The EDG will continue to run with cooling. ACB E-9 is unaffected and even if it did open, EDG cooling would maintained from the other train since RW is cross connected at the CCR HX's. It is not RO knowledge to select procedures so therefore only first part of the higher cognitive KIA was Incorrect.

Correct that EDG 1-1 remains running, incorrect that it is running without cooling. Plausible if the candidate believes the overcurrent trip opens ACB 1 E-9 and does not recognize or understand the RW system configuration. (common misconception based on prior plant configuration).

Correct that #2 occurs, however, #1 will occur from RM-1 VS-11 048 ONLY. Plausible because during fuel movement when fuel is longer irradiated, the auto closure of these dampers are defeated.

Incorrect because RM-1 VS-1 04A is Incorrect.

If RM-1 VS-1 04A was not out of service, 1 VS-HV-S, CNMT Purge Supply Fan and 1 VS-F-S CNMT Purge Exhaust Fan both will 1 VS-D-S-3A and 1 VS-D-S-SA will both close to isolate the CNMT from Incorrect.

Containment Evacuation alarm is actuated from RM-1 VS-1 048 ONLY which is OOS. Correct. No automatic actions occur from RM-1 VS-1 09. The procedure requires the operating crew to monitor for increased radiation consider manual isolation if a high radiation condition exists. This is operationally relevant to the way 8VPS is currently operated.

These are indicative of a reactor trip with failure of steam dumps. Correct. Since the reactor is> P-9 (49%) a turbine trip results in a reactor trip. A reactor trip will result in an initial drop in RCS temperature since steam dumps will open to maintain RCS temperature at 547 F. The RCS cooldown results in a loss of fluid in the PRZR which in turn drops RCS pressure initially until steam dumps close and PRZR heaters can compensate for the cooldown.

o Core Exit Thermocouple Temperatures are 472 OF and slowly DROPPING.

oRCS loop cold leg temperatures are 290 OF and slowly DROPPING.

o S/G pressures are 800 psig and slowly DROPPING.

oRCS Ll T is indicating UPSCALE. RCP's are NOT running. Based on these conditions, which ONE of the following identifies the source(s}

of SI flow providing core cooling, AND what is the status of natural circulation?

A. High Head SI flow ONLY; Natural Circulation is occurring.

B. High Head SI flow ONLY; Natural Circulation is NOT occurring.

C. High Head AND Low Head SI flow; Natural Circulation is occurring.

D. High Head AND Low Head SI flow; Natural Circulation is NOT occurring.

Answer: B Explanation/Justification: Incorrect.

Correct SI flow but incorrect natural circulation conclusion (refer to correct answer explanation) Correct. With RCS pressure at 520 psig. the High Head 81 pumps will be supplying SI flow for core cooling only. The shutoff head for the Low Head 81 pumps is about 178 psig so therefore will not be providing flow. Natural circulation is not occurring.

Decreasing CETCs, Tcold and upscale AT are all indicative of natural circulation making it plausible that natural circulation is occurring.

However the candidate must recognize that there is a disconnect between S/G pressures and cold leg temperatures.

Saturation temperature for S/G pressures at 800 psig is 520 F. Tcold is well below this temperature implying the cold down is more indicative of SI flow. Break flow is the primary removal mechanism and based on saturation temperature for S/G pressure although some reflux boiling may occur. conditions for natural circulation are not present. Both ES-1.1 & 1.2 reference Attachment 2-G for verification of natural circulation flow in the LOCA series procedures making this question operational relevant Incorrect.

(1) manually trip the reactor. (2) 30% (3) Power Range Reactor Trip Signal. Answer: B Explanation/Justification: Incorrect.

Inserting control rods is a correct action if criticality is achieved early or outside expected rod height lAW 10M-50.4.4.D.

Since there is an intermediate rod stop at 20%, this is a plausible distractor.

Also AOP 1.1.3 RNO directs the operator to place the rod group selector to Manual. Since the rods are already in manual, the candidate may confuse actions and think taking the control switch to a position other than manual is a correct action. Correct. The candidate must interpret indications provided and recognize an uncontrolled rod withdrawal is in progress and then apply immediate action and systems knowledge to demonstrate understanding of operator actions and impact on system conditions if these actions are not taken. Step 1 of AOP 1.1.3 (RCCA Control bank Inappropriate Continuous Movement) checks for load rejection.

Since the turbine is not yet in service, the RNO Immediate Action is applicable.

Since rods are already in MANUAL and a continuous rod withdrawal is occurring based on symptoms provided, the RO shall trip the reactor. A reactor trip will automatically occur in this scenario when 214 power range channels are above 25% because the low power trip was not manually blocked above P-10 (10%) because no operator action is taken. Incorrect.

Incorrect action as discussed.

It is correct that a reactor trip 'Will occur at 25% based on intermediate current equivalent neutron flux. Incorrect.

Beaver Valley Unit 1 NRC Written Exam (1LOT8) According to NOP-OP-4202, "Declared Pregnant Workers" and NOP-OP-4201, "Routine External Exposure Monitoring", which ONE of the following Beaver Valley Occupational Dose Limits are required? (Assume no extensions or planned special exposures)

The Embryo/Fetus Dose Equivalent (EFDE) Limit for a Declared Pregnant Worker over entire gestation period is _ The Site Administrative Control Level Dose Limit (TEDE) for an individual working at the Nuclear Facility is _ (1) 100 mr/term (2) 2000 mr/year (1) 500 mr/term (2) 1000 mr/year (1) 100 mr/term (2) 1000 rnr/year (1) 500 mr/term (2) 2000 mr/year Answer: B Explanation/Justification: Incorrect.

Incorrect but plausible DPW limit. The DPW is limited to 100 mr/month but may have up to 500 mr for the entire term or gestation period. The Annual Administrative Limit for an individual working at a nuclear facility is incorrect because it reflects a BVPS Administrative Limit where extensions are involved.

The stem of the question specifically excludes extensions or planned special exposures. Correct. According to NOP-OP-4201 Attachment B. when a worker declares pregnancy.

she will have an administrative level of 500 mr for the term of pregnancy.

This ensures the dose to the unborn child is minimized.

The federal limit is also 500 mrem for the pregnancy period or term. NOP-OP-4101 refers the reader to NOP-OP-4202 which defines a declared pregnant worker and specifies the occupational dose limit for the entire period of declared pregnancy is 500 mrem (100 mrem/month)

NOP-OP-4101 states on Attachment A that BVPS Administrative Control Limit for TEDE is 1000 mr/year. Incorrect.

Incorrect DPW value but plausible as described above. Correct BVPS Administrative Control Limit for TEDE. Incorrect.

Correct value for DPW. Incorrect value for BVPS Administrative Control Limit for TEDE. however plausible because it reflects the initial annual ACL limit for TEDE when dealing with extensions.

Plausible if candidate does not recognize this is a HRA does not know the Access Control & Briefing requirements. (refer to correct answer Correct. NOP*OP*4101 defines a HRA an accessible area in which radiation levels could result in an individual receiving a deep-dose equivalent in excess of 100 mr/hr at a distance of 30 cm or more from any surface that the radiation penetrates.

The candidate must recognize that they are entering a HRA versus RA and then differentiate the briefing and access requirements in order to comply with RWP requirements.

NOP*OP*4107, "Radiation Work Permit" requires radiation protection briefings to ensure compliance with RWP requirements when entering HRAs. For entry into radiation areas considered to be low risk, operators are allowed to self brief and do not need formal briefings.

According to NOP*OP*41 01 , For entry into a HRA, a trip ticket and dose alarm augmentation device are required.

This is a higher level question because it goes beyond simple recall and requires comprehension of the operationally relevant task to be performed. Incorrect.

Incorrect because NOP*OP*4107 allows self briefing for entry into low risk areas ONLY. Since this is a HRA it is considered higher risk. Plausible if the candidate recognizes this is a HRA but does not know the RWP briefing requirements. (refer to correct answer explanation).

D. (1) 60% (2) ensure Safety Limit criteria will be met for postulated accidents.

Answer: A Explanation/Justification: Correct. According to UFSAR analyzed partial loss of forced reactor coolant flow, idle loop flow will be about 30% of nominal flow. This accident assumes 100% power and has a conservative number of S/G tubes plugged which will effect head loss. When run on the simulator from 25% power RCS flow in the idle loop is about 20%.

D. (1) can NOT (2) SR 3.0.2 can NOT be used to extend the time for inoperable inverters.

Answer: A Explanation/Justification: Correct. TS Use and Application Section 1.3 discuss use of completion times. All of the criteria for use of the completion time extension apply, specifically that the first inverter and second inverter were concurrently inoperable and the second inverter remains inoperable after the first inverter is declared operable.

Also there is no exception that allows separate entry conditions for inverters in TS 3.8.7, so therefore the extension time can be applied. The SRO must determine whether completion time extensions are applicable and explain the bases for the decision. Incorrect.

Incorrect that the extension time cannot be applied. The logic is opposite of the correct answer. Incorrect.

Correct that extension can be applied (refer to correct answer explanation)

Incorrect that SR 3.0.2 can be applied to the inverters since the second inverter failed and was not part of a surveillance.

An RO should be able to differentiate between these indications to determine whether an air leak is inside or outside containment.

AOP 1.34.1 step 4 does use this diagnostics to determine procedural flowpath.

The second part of the question is SRO knowledge because it requires the candidate to have knowledge of procedure content and bases for the reason the action is being taken beyond assessment of plant conditions.

AOP 1.34.2 asks whether Station IA is < 95 psig and directs isolation of 1IA*90 if all available station air compressors are running which they would be if functioning as designed.

This is to ensure Containment Air is isolated from Station Air which is being dragged down by the Containment Air sizable air leak. TS 3.6.3 is not the reason for isolation because although the plant is in Mode 3 and CI valves are required to be operable the operator is not closing 11A-90 to comply with TS 3.6.3 because there is no TS bases accident in progress (ie: LOCA or Rod Ejection Accident).

TS 3.6.3 action is applicable but not the reason for directing 11A-90 closure. The competent SRO should know the bases for TS action and must understand the loss of air accident is not the basis. Incorrect.

Stop all charging pumps and assess signs of containment sump blockage per ES-1.3. D. Stop all charging pumps and low head safety injection pumps, then transition to ECA.1-1. Answer: C Explanation/Justification: Incorrect.

Plausible since a red path normally would take priority however, FRP's should not be implemented prior to completion of the first steps of Incorrect.

Transition to FRPs is not allowed by note during Steps 1-5. Step 1 checks to ensure containment sump level is > 48 inches. Step checks that a recirculation path is indicated.

If either of these conditions do NOT exist a transition to ECA-l.1 is warranted which makes distractor Correct. The SAO must assess plant conditions and have knowledge of diagnostic steps and decision points in the EOPs which involve transition to event specific sub procedures in order to answer this question.

Specifically, they must recognize that oscillating amps and flow of the LHSI pumps is indicative of LHSI pump cavitation.

Because cavitation exists, they must have knowledge of the RNO action which is to stop charging pumps. An assessment of containment sump blockage must occur prior to transition.

Securing charging pumps prior to transition preserves them from further damage so that they may be available in the long term. The candidate must further understand because they are in step 5 of ES-l.3 that the RED path on heat sink is not to be implemented although contrary to FRP rules of usage.

In the set of conditions provided, although only the "A" MSIV went shut, all S/G pressures continue to drop which is indicative of a beyond design basis accident (3 faulted S/Gs). Realistically for this scenario to happen all three S/Gs would need to have partially stuck open safety valves on all three S/Gs.

(SRO Beaver Valley Unit 1 NRC Written Exam 82. Given the following plant conditions and of events:

The Unit is at 75% power with all systems in NSA for this power level.

The Control Room Team notes that control rods are withdrawing at maximum speed.

The RO places rods in MANUAL and control rods have stopped moving.

The following annunciators are LIT and confirmed VALID: o A5-3, NIS 2/3 PWR RANGE NEUTRON FLUX RATE HIGH REACTOR TRIP o A5-4, 2/3 LOOPS OVERTEMP AT REACTOR TRIP

The RO reports that Reactor Trip Breakers are CLOSED. Reactor Power is 80% and STABLE. Which ONE of the following identifies (1) the procedural required actions to mitigate this event, AND (2) includes the action required if the crew is unable to verify emergency boration flow> 30 gpm in accordance with FR-S.1, "Respons1e to Nuclear Power Generation/ATWS"?

A. (1) Enter FR-S.1 directly, manually trip the turbine, and insert control rods. (2) Manually align Charging Pump suction to HWST. B. (1) Attempt to manually trip the reactor in E-O, if unsuccessful, then transition to FR-S.1. (2) Manually align Charging Pump suction to HWST. C. (1) Enter FR-S.1 directly, manually trip the turbine, and insert control rods. (2) Initiate boration > 30 gpm with the blender in BORATE mode. D. (1) Attempt to manually trip the reactor in E-O, if unsuccessful, then transition to FR-S.1. Initiate boration > 30 gpm with the blender in BORATE mode. Answer: B Explanation/Justification: Incorrect.

Although both E*O and FR-S.1 both have immediate actions with similar intentions (ie: trip the reactorlturbine), FR-S.1 by WOG rules of usage is not a direct entry procedure such as E-O and ECA-O.O. Knowledge of administrative procedures that specify hierarchy implementation is SRO level knowledge.

The second part of the distractor is correct (explained in correct answer) Correct. The SRO must interpret the annunciators and indications provided and deduce that entry conditions of E-O are applicable and by WOG rules of usage E-O must be entered. FR-S.1 is entered only from E-O or from a CSFST. The SRO must also understand FR-S.1 procedural content of sufficient detail to understand what alternative actions are required to ensure the reactor is safely shutdown as directed by FR-S.1. Step 3.e RNO requires the charging pumps aligned to the RWST if 30 gpm emergency boration cannot be established.

This is to ensure adequate negative reactivity insertion. Incorrect.

Incorrect procedure as explained above. Incorrect action. This action is plausible since both ES-0.1 and FR-S.1 specify a 30 boration as an action to insert negative reactivity.

This action however procedurally specifies opening MOV-1CH-350 and starting a boric transfer pump as opposed to using the blender in the borate mode at the same Incorrect.

Correct procedure.

Incorrect action (refer to previous explanations).

Given the following plant conditions: The Unit experienced a MANUAL Reactor Trip during a reactor startup due to Hi-Hi S/G Water Level in "en Steam Generator. PRZR pressure dropped to 1890 psig and is RISING. Immediate Manual Actions of E-O, "Reactor Trip or Safety Injection" are in progress. The RO reports TWO control rods are indicating 225 steps. All systems function as designed.

What procedure action will be required to ensure adequate shutdown margin? A. Manually actuate SI. B. Commence normal boration.

C. Commence emergency boration.

D. Manually actuate SI and emergency borate. Answer: C Explanation/Justification: Incorrect.

Incorrect that manual SI is required based on plant conditions (SI not required unless RCS pressure < 1845 psig), however, plausible if the SRO makes the decision at Step 4 of E-O that SI is required.

The design of ECCS is to provide core cooling and boration to maintain a safe reactor shutdown condition.

If SI were required this would be a correct answer. Incorrect.

Correct assessment of plant conditions that no SI has occurred or is required, however. ES-0.1 directs an emergency versus boration which is plausible if the SRO does not know procedural Correct. The SRO candidate must assess given plant conditions and determine that no SI injection is required based on stated plant conditions.

Therefore the SRO shall make the decision at Step 4 of E-O to transition to ES-O.1. Step 7 of ES-0.1 verifies all control rods inserted and if directs emergency boration if two or more are not fully inserted.

The SRO must know the content of procedures beyond immediate actions. Incorrect.

Incorrect that manual SI is required and also incorrect since emergency boration is not required.

Plausible if the candidate believes SI is required and the decision to remain in E-O at step 4 is made and that they have ES-0.1 and E-O actions/bases confused.

Correct system response.

Incorrect that zero RCS Loops are ,operable lAW TS 3.4.6 bases. To ensure the candidate does not challenge the fact that RCPs are operable.

it is added to the stem of the question.

This is still highly plausible because they must possess the knowledge that RCS loops are operable based on SIG water level> 15.5% and Reps need not be running. Incorrect.

Incorrect system response.

This reflects system response if MOV-1 RH*758 failed open. Also reflects an accurate configuration if were separate RHR loops. similar to Unit 2 design. Incorrect that zero RCS loops are operable (refer to explanation Correct. If MOV*1 RH-700 fails closed. system flow as indicated by FT-1 RH-605 will drop significantly.

Since no suction from the RCS loop to the RHR pump is available.

the pump will continue to run and recirculate whatever water is left in the RHR loops. In accordance with the TS 3.4.6 bases an OPERABLE RHR loop comprises an operable RHR pump capable of providing forced flow to an operable RHR HX. RCPs and RHR pumps are operable if they are capable of being powered and are able to provide forced flow if required.

Since MOV-1 RH-700 is in the flowpath and not capable of being opened. RHR must be declared INOPERABLE.

An operable ReS loop on the other hand comprises an operable RCS and operable S/G. which has minimum water level specified in SR 3.4.6.2 (>28 %). Therefore RCS Loops are operable.

This question requires the SRO to make an operability determination based on system knowledge and TS bases. 1/20M-48.1.1 requires the SRO to make timely operability determinations in order to control and correct the non conforming condition. Incorrect.

(1) THREE (2) To determine cold leg to hot leg switchover time. Answer: A Explanation/Justification: Correct. According to TS 3.5.1 Bases background/LCO, The accumulator size, water volume, and nitrogen cover pressure are selected so that two of the three accumulators are sufficient to partially cover the core significant clad melting or zirconium water reaction can occur following a LOCA. One of the three accumulators is assumed to be lost via the RCS break during the blowdown phase of a LBLOCA. The LCO establishes minimum conditions required to ensure accumulators are available to accomplish their core cooling safety function following a LOCA. Three accumulators are required to ensure that 100% of the contents cr'two will reach the core. If less than two accumulators are injected during the blowdown phase of a LOCA, the ECCS acceptance criteria of 10 CFR 50.46 could be violated.

Correct A6*35 status (refer to correct answer explanation).

Incorrect that TS 3.0.3 action is required.

Plausible because based on stated conditions, there are no CCW pumps running. TS 3.7.7 action for two CCW pumps inoperable is to immediately restore which is applicable in Mode 4 when RHR is required to C/D plant based on Note. The plant is currently in Mode 3 based on reactor trip. This note could be misapplied to mean that since two trains are not available in Mode 3 that TS 3.0.3 is required. Incorrect.

AS-35 is LIT based on no CCR pumps running. Plausible if candidate does not understand that EDG auto loading if two CCR pumps are racked onto the emergency bus. Incorrect plausible TS LCO action (explained above). Correct. AS-35 will be LIT. With no offsite power, the only source of power to emergency busses is from the EDG. Since #2 EDG did not start, the B CCR pump is not running. Since there are two pumps racked onto the AE bus, #1 EDG will not auto sequence on "C" CCR pump and is rendered inoperable.

The required action in accordance with ES-0.4 to mitigate this condition is to __ (1) __. The impact of PRZR heater unavailability is the inability to (2) __. A. (1) stop the depressurization (2) partially or wholly collapse the Rx Vessel Void. B. (1) maximize letdown (2) prevent a water solid RCS and resultant loss of pressure control. C. (1) maximize letdown (2) partially or wholly collapse the Rx Vessel Void. D. (1) stop the depressurization (2) prevent a water solid RCS and resultant 10:5s of pressure control. Answer: A Correct. Step 8 of ES-0.4 directs depressurization stopped if PRZR level exceeds 90% or if 800 psig is reached. PRZR heaters are necessary in step 9 to raise RCS pressure 100 psig to collapse the reactor vessel void formation.

This is SRO level knowledge based on the need to assess plant conditions and understand how to proceed based on understanding of procedure content. In this situation there is no method to continue in this procedure without PRZR heater control. A procedural do-loop occurs. PRZR heaters are necessary in ES-0.4 for PRZR level control to enhance upper head COOling. Incorrect.

This is a required action and bases in ES-O.3 for high PRZR level where the technique employed for RCS cooldown is different Under normal circumstances, with the RCS subcooled, this would be correct. However, with a void in the vessel the RCS will not water solid. Candidate may mis-interpret high PRZR level as an indication of a "water solid" Incorrect.

A4-76, COMPUTER ALARM ROD DEVIATION/SEQ NIS POWER RANGE TILTS is LIT. Individual Rod Position Indication (IRPI) for Control Rod D4 (Bank C) indicates 30 steps.

Reactor power indicates 34% and is SLOWLY RISING.

The SRO enters AOP 1.1.8, "Rod IRPI system functions as designed.

For these conditions, what will be the status of VB-B Control Rod D4 Rod Bottom Light AND what action is required in accordance with AOP 1.1.8? The VB-B Control Rod D4 Rod Bottom Light will __ (1) __The required action will be to direct a __ (2) __(1) be LIT. (2) turbine load reduction. (1) be LIT. (2) reactor trip. (1) NOT be LIT. (2) turbine load reduction. (1) NOT be LIT. (2) reactor trip. Answer: C Explanation/Justification: Incorrect.

Incorrect RPIS impact. Rod Bottom Light setpoint is < 20 steps. 30 steps was chosen as a distractor because it is close to the setpoint that is used on a reactor startup to detect subsequent dropped rods onc:e CBA is withdrawn above the 35 step rod bottom bypass setpoint.

Correct procedure use. A load reduction is warranted and procedurally driven in AOP 1 :1.8 to stabilize RCS Tavg within 4 F of Tref. Incorrect.

Incorrect RPIS impact. Rod Bottom Light setpoint is < 20 steps. Incorrect procedural action. This action is plausible if Tavg is < 541 F or after load reduction Tavg is not stable (ie: on a declining trend & > 10F below Tret). Correct. The impact of a dropped rod on RPIS is the receipt of a Rod Bottom Light which corresponds to an IRPI position of < 20 steps. Since the rod dropped to 30 steps, the rod bottom light will not be lit. AOP 1.1.8 directs a turbine load reduction if RCS Tavg is not within 4 F of Tref. The candidate must determine that Tref for 34% is about 557 F which means Tavg is 12 F outside the required band. Since these conditions are met, a turbine load reduction is required.

Because the turbine load reduction has been commenced, Tavg will begin to increase and therefore will not be on a declining trend, so therefore a reactor trip is not warranted.

It is required SRO knowledge to understand the content of procedures beyond IMA's. This is relevant BVPS OE. Incorrect.

Which ONE of the following activities can be performed WITHOUT violating the Technical Specification required actions for Source Instrumentation?

A. Install a temporary secondary source into a core location.

B. Move a spent fuel assembly from the core to the Spent Fuel Pool. C. Move a spent fuel assembly from the upender to the Spent Fuel Pool. D. Add Hydrogen Peroxide mixed with primary grade water to the refueling cavity for cleanup. Answer: C Explanation/Justification: Incorrect.

Plausible that operationally an alternative source could be installed to replace N31, however, it is not allowed by definition. Incorrect.

Moving a fuel assembly from the core would not be allowable by definition.

Removing the assembly would not be considered placing the assembly in a safe location.

This is plausible however, the safest location would be back into the core as opposed to removal from the core. This is further plausible because some TS such as TS 3.9.4 LCO preclude core onload but do allow core offload to continue. Correct. Both AOP 1.2.1A for SR Channel Malfunction and TS 3.9.2 direct that core alterations are immediately suspended.

Core alterations defined as movement of any fuel, sources, or reactivity components, within the reactor vessel with the vessel head removed and with fuel in vessel.

Measurements taken on pipes and valves include: Point 1 is 100 mr/hr at 30 cm. Point 2 is 500 mr/hr at 30 cm. Point 3 is 1100 mr/hr at 30 cm. Based on these plant conditions, what is the radiological posting required AND which entry requirements are applicable according to NOP-OP-41 01, "Access Controls for Radiologically Controlled Areas"? Radiological posting required (2) NOP-OP-4101 Entry Requirements A. (1) Very High Radiation Area. (2) Shift Manager must grant access. B. (1) Very High Radiation Area. Radiation Protection must grant access. C. (1) Locked High Radiation Area. (2) Shift Manager must grant access. Only key will be required to gain access. D. (1) Locked High Radiation Area. Radiation Protection must grant access. Two keys are required to gain access. Answer: C Explanation/Justification: Incorrect.

A Very High Radiation Area is defined as an accessible area in which radiation levels could result in an individual receiving an absorbed dose in excess of 500 Rlhr at a distance of 1 meter or more from a radiation source or any surface that radiation penetrates.

The candidate could confuse 500 r/hr with mr/hr requirements.

To the ex1ent possible, entry into a VHRA should be forbidden unless there is a sound operational or safety reason for entering.

Although entering to isolate a safety related system during EOPs does meet this criteria, it is not a VHRA. Both SM and RP permission is required to enter a VHRA. Incorrect.

Refer to discussion above. Correct. A Locked High Radiation Area is defined as an accessible high radiation area in which radiation levels could result in an receiving a deep dose in excess of 1000 mr/hr at a distance of 30 centimeters or more from a radiation source or any surface that penetrates.

When IA is restored, return to Step 7 of E-3 and continue subsequent E-3 steps. Stop at this step in E-3. Transition to AOP 1.34.1. When IA is restored, return to Step 7 of E-3 and perform EOP Att. 2-S. Continue in E-3 without performing AOP-1.34.1.

Attempt to restore IA using E-3 Step 7. If IA cannot be restored, perform EOP AU. 2-S. Continue in E-3 and concurrently perform AOP-1.34.1.

Attempt to restore IA using AOP 1.34.1. When IA is restored, continue in E-3 and perform EOP Att. 2-S. Answer: C Explanation/Justification: Incorrect.

EOPs are higher priorities than AOPs. Although plausible that AOP 1.34.1 is used, Step 7 RNO does not refer to usage of AOP 1.34.1. Incorrect.

There is no direction to concurrently use AOP 1.34.1 during performance of E*3. EOP Att 2*S is only performed if IA is not restored. Correct. The intent of E-3 is to get S/G pressure equalized with RCS as soon as possible to stop primary to secondary leakage. This can be accomplished without IA which is not required per design bases. Step 7 is a continuous action step and attempts to restore IA should be continued.

The SRO needs to prioritize procedures and E-3 has the overriding priority and does not direct concurrent use of AOP 1.34.1. Step 7 RNO does direct performance of Attachment 2-S if IA is not restored because AFW recirculation valves fail closed and this could damage the AFW pump if there is insufficient flow. This is an important concept that the SRO must be aware of, otherwise AFW could be jeopardized.

This is an SRO level question because it requires an assessment of Loss of IA impact on E-3 and knowledge of procedure content and diagnostic steps in E*3. The KIA is met because E-3 is a higher priority than AOP 1.34.1. The SRO must know this procedure is not used in conjunction with E-3. Incorrect. Refer to correct answer explanation.

There is no direction to concurrently use AOP 1.34.1 during performance of E-3. Step 7 does direct Attachment 2-S usage if IA is not restored, however, IA is restored so therefore is unnecessary to perform. The background document and step bases is more concerned with restoration of air to ensure AFW recirculation.

EOP Attachment 2S is referenced if air header pressure cannot be restored.
