QUESTIONS REPORT for SRO exam written 03-2013
- 1. Given the following:
- Unit 1 is operating at 100% power.
- Annunciator 138-E, PANEL M-9 MOTOR TRIPOUT, alarms and it is determined the CRDM Cooler 1 D-B fan tripped.
- Fire Safe Shutdown Equipment, OR-14.10.1, is entered.
- Before the operating crew can place an additional CRDM fan in service, the elevated CRDM temperatures result in changes in the indicated rod positions on the CERPI monitors.
- The unit remains stable at 100% power with no indication of actual rod movement.
Which ONE of the following completes the statements below?
Tech Spec 3.0.3 would be first required to be entered due to inoperable rod position indications (ARPI) when more than one ARPI in a single IL indicated greater than the allowed deviation in accordance with Tech Spec LCO 3.1.8, Rod Position Indication.
For the Unit to remain in MODE 1 with CRDM Cooler 1 D-B INOPERABLE beyond the OR-14.10.1 allowance of 30 days requires {) of an engineering evaluation to justify using alternate means to provide FSSD.
A. group approval by the NRC B group performance and documentation C. bank approval bythe NRC D. bank performance and documentation Wednesday, March 13, 2013 9:16:27 AM
QUESTIONS REPORT for SRO exam wriffen 03-2013 DISTRACTOR ANAL YSIS:
A. Incorrect, Plausible because the LCO 3.0.3 entry being required when more than one APR! in a single group exceeded the 12 step deviation limit is correct.
Also because OR-14. 10 contains a requirement similar to Tech Spec 3.0.3 such that if an inoperable component could not be restored within the time allowed by the LCO Condition, a Mode reduction is required. To prevent an LCO 3.0.3 required Mode reduction, NRC approval would be required, but the pre-approval by the NRC for actions taken to provide alternate means to provide FSSD for the fan failure is not required by OR-14-10.
B. Correct, LCO 3.1.8, Rod Position Indication, would be entered when an RPI exceeded 12 steps deviation from its demand position indication (step counter).
The LCO provides an action for One APR! per group for one of more groups but does not provide an action for more than one APR! in a single group. The LCO 3.0.3 entry would be required when more than one APR! in a single group exceeded the 12 step deviation limit. Fire Protection Plan OR- 14.10.3 requires the unit to be placed in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 4 within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> if the fan is not restored to operable status within 30 days unless an evaluation justifies the use of alternate means to provide FSSD, but the evaluation does not require pre-NRC approval.
C. Incorrect, Plausible because the control rods are arranged in 4 banks with 2 groups in each bank. This provides the opportunity to incorrectly associate the LCO requirement to be more than one rod in a bank versus the correct association with a group. This misconception is valid because Condition C in the same LCO contains the Required Action to Verify the most withdrawn rod and the least withdrawn rod of the affected banks are less than or equal to 12 steps apart when a demand position indicator (step counter) has failed. Also because OR- 14.10 contains a requirement similar to Tech spec 3.0.3 such that if an inoperable component could not be restored within the time allowed by the LCO Condition, a Mode reduction is required. To prevent an LCO 3.0.3 required Mode reduction, NRC approva! would be required, but the pre-approval by the NRC to actions taken to provide alternate means to provide FSSD for the fan failure is not required by OR- 14-10.
- 0. Incorrect, Plausible because the control rods are arranged in 4 banks with 2 groups in each bank. This provides the opportunity to incorrectly associate the LCO requirement to be more than one rod in a bank versus the correct association with a group. This misconception is valid because Condition C in the same LCO con tains the Required Action to Verify the most withdrawn rod and the least withdrawn rod of the affected banks are less than or equal to 12 steps apart when a demand position indicator (step counter) has failed. Also because the OR- 14.10 allowance for completion of an evaluation to establish an alternate means to provide FSSD is correct.

Wednesday, March 13, 2013 9:16:27 AM 5
QUESTIONS REPORT for SRO exam wriffen 03-2013 DIS TRACTOR ANAL YSIS:
A. Incorrect, Plausible because if the safety valve upstream of the orifices was determined to have lifted instead of the safety valve downstream of the letdown heat exchanger, then the letdown flow would have been directed to the PRY resulting in exceeding the LCO 3.4.13 limit for identified leakage. Also because using SOl-62.O1, CVCS-Charging and Letdown, Section 8.18, Bypassing Reactor Coolant Fl/tee to mitigate the effect of the conditions is correct.
B. Incorrect, Plausible because if the safety valve upstream of the orifices was determined to have lifted instead of the safety valve downstream of the letdown heat exchanger, then the letdown flow would have been directed to the PRT and resulted in exceeding the LCO 3.4.13 limit for identified leakage. Using Section 8.15, Bypassing 1-PC V-62-81, CVCS LETDOWN HX PRESS CNTL, for Local Control. is also plausible because all of the indications would exist for a malfunctioning PCV except for the pressure on the Reactor Coolant filter (which would have been lower).
C. Correct, Applicant is required to determine how the conditions effect the system flow path with a safety valve being forced to open (setpoint 200 psig) While the provided conditions do not directly identify the CVCS Reactor Coolant filter is plugged and needs to be replaced, the applicant should be able to determine they exist by evaluation of the filter inlet pressure. Conditions to replace the filter will be established using SQI-62.01, CVCS-Charging and Letdown, Section 8.18, Bypassing Reactor Coolant Filter. The WBN simulator was used to determine conditions in the stem with the filter 100% plugged.
- 0. Incorrect, Plausible because the safety valve downstream of the letdown heat exchanger relieves to the VCT which is the same flow path as would exist if the flow was through the filter, thus LCO 3.4.13 limit for identified leakage not being exceeded is correct. Using Section 8.15, Bypassing 1-PCV-62-81, CVCS LETDOWN HX PRESS CNTL, for Local Control is also plausible because all of the indications would exist for a malfunctioning PCV except for the pressure on the Reactor Coolant filter (which would have been lower).
Question Number: 86 Tier: 2 Group: 1 K/A: 004 A2.23 Chemical and Volume Control System Ability to (a) predict the impacts of the following malfunctions or operations on the CVCS; and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations:
High filter D/P Importance Rating: 2.6 /2.7 Wednesday, March 13, 2013 9:16:27 AM 6
QUESTIONS REPORT for SRO exam written 03-2013 10 CFR Part 55: 41.5 /43/5 / 45/3 / 45/5 10CFR55.43.b: 5 K/A Match: K/A is matched because the question requires the ability to understand the impact of a High filter DIP on the CVCS Reactor Coolant filter (causing the opening the safety valve on the letdown line downstream of the letdown heat exchanger) and then identifying the condition exists so that the correct procedure will be implemented to mitigate the consequences of the plugged filter.
SRO ONLY: Question is SRO because it requires both assessing plant conditions to determine application of Tech Spec RCS Operational leakage LCO and then selecting a section of a procedure to mitigate the consequences of the abnormal plant conditions.

QUESTIONS REPORT for SRO exam written 03-2013 DISTRACTOR ANAL YSIS:
A. Correct, The shunt trip coil (S TB) in parallel with the UV coil on RTB will be energized to trip RTB. However BYA does not have the STB coil, so the SSPS trip functions only de-energize the UV relay for the BYA. Therefore, the BYA will not open. In accordance with NPG-SPP-03.5, Section 3.1.3 this is a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> report.
B. Incorrect, the first part is plausible because the RTB will open and the BYA would open if the breakers had been equipped with the shunt trip coil contained on the RT breakers. The second part is plausible because it is correct.
C. Incorrect, the first part is plausible as it is correct. The second part is plausible because an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> report is required when to the reactor trip breakers open due to a trip during a condition when the reactor is not critical.
D. Incorrect, the first part is plausible because the RTB will open and the BYA would open if the breakers had been equipped with the shunt trip coil contained on the RT breakers The second part is plausible because an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> report is required when to the reactor trip breakers open due to a trip during a condition when the reactor is not critical.
C. The following criteria require 4-hour notification:
- 1. §50.72(b)(2)(i) The initiation of any nuclear plant shutdown required by the plants Technical Specifications.
- 2. §50.72(b)(2)(iv)(A) Any event that results or should have resulted in Emergency Core Cooling System (ECCS) discharge into the reactor coolant system as a result of a valid signal except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.
- 3. §50.72(b)(2)(iv)(B) Any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.

QUESTIONS REPORT for SPO exam written 03-2013 DIS TRACTOR ANAL YSIS:
A. Correct, The procedure has provisions for starting a RCP that must be met to accommodate the presence of a head bubble. The pressurizer level is required to be above 90% or increased until the level stops rising. The procedure also has a monitoring step to compare the drop in RWST level to the rise in the containment sump level. With no rise in sump level the transition to 1-ECA-3.2 is required when the RWST level drops to approximately 68%.
B. Incorrect, The ruptured S/G level dropping would not require a transition to 1-ECA-3.2. Plausible because the pressurizer level being required to be raised is correct and the ruptured S/G level is monitored to determine a need to transition to 1-ECA-3.2 but it is made on a rising level not a dropping level.
C. Incorrect, Subcooling is not required to be raised in order start an RCP because it is above the minimum required value. Plausible because RCS subcooling is affected and monitored during the step and because the RWST dropping could result in a transition to 1-ECA-3.2.
D. Incorrect, Neither Subcooling being required to be raised nor Ruptured S/G level dropping is correct. Plausible because RCS subcooling is affected and monitored during the step and the ruptured S/G level is monitored to determine a need to transition to 1-ECA-3.2 but it is made on a rising level not a dropping level.

QUESTIONS REPORT for SRO exam written 03-2013 DIS TRACTOR ANAL YSIS:
A. Incorrect, Plausible because TR-3.6.3 requires two LCC trains with two fans in each train to be OPERABLE and unless the Bases information is known it is reasonable to conclude that a loss of cooling medium would render the component to be INOPERABLE. Second part plausible because the SO! has precautions relating to maintain a balance of flows by running fans both fan rooms and there is nothing in the description of the ERCW valves that are isolated to indicate ERCW flow has been lost to the CRDM cooler iC-A even though the flow has been lost.
B. Incorrect, Plausible because TR-3.6.3 requires two LCC trains with two fans in each train shall be OPERABLE and unless the Bases information is known it is reasonable to conclude that a loss of cooling medium would render the component to be INOPERABLE. Also plausible because the second part (Aligning CRDM cooling fan iD-B for supplemental cooling in lower containment) is correct.
C. Incorrect, Plausible because not being required to comply with a TR-3.6.3 required action is correct as the fans are not required to perform a cooling function by the TR. Second part plausible because the SO! has precautions relating to maintain a balance of flows by running fans both fan rooms and there is nothing in the description of the ERCW valves that are isolated to indicate ERCW flow has been lost to the CRDM cooler iC-A even though the flow has been lost.
D. Correc1, As identified in TR-3.6.3 Bases The LCC fans do not perform a cooling function, which means that the coils and the secondary cooling water circuits need not be OPERABLE. The TR specifies the equipment which needs to be OPERABLE in order to ensure that air can be circulated in the sub-compartments if an accident should take place. Aligning CRDM cooling fan iD-B for supplemental cooling in lower containment is correct because CRDM iC-A fan does not have ERCW available due to the ERCW isolation in the question.

QUESTIONS REPORT for SRO exam written 03-2013 DISTRACTOR ANAL YSIS:
A. Incorrect, the pressure is not correct for the heaters. Plausible because 2217 psig is the nominal pressure the Pressurizer backup heaters will automatically de energize and because allowing the unit to remain at 100% power (CONDITION B exited) after with the pressure is restored to greater than the minimum is correct.
B. Correct, The LCO is required to be entered when the pressurizer pressure dropped to below 2214 psig (see below) and with the pressure restored to greater than the minimum both CONDITION A and CONDITION B can be exited allowing the unit to remain at 100% power.
C. Incorrect, Neither the pressure nor the required action of CONDITION B being completed is correct. Plausible because 2217 psig is the nominal pressure the Pressurizer backup heaters will automatically de-energize and there are conditions that must be completed once they have been entered (e.g. RCS Chemistry TR) and because the allowed time for completion of CONDITION A had been exceeded.
D. Incorrect, The completion of Condition B required actions is not required in this LCO. Plausible because entering the LCO when the pressurizer pressure drops to less than 2214 psig is correct and there are conditions that must be completed once they have been entered (e.g. RCS Chemistry TR) and because the allowed time for completion of CONDITION A had been exceeded.

QUESTIONS REPORT for SRO exam written 03-2013 DISTRACTOR ANAL YSIS:
A. Incorrect, Plausible because the Safety Injection initiation is when the first of two requirements for an NOUE classification are met (but it takes both) and the correct classification is an NOUE.
B. lncorrecI, Plausible because the Safety Injection is when the first of two requirements for an NOUE classification are met (but it takes both) and the classification being an ALERT is plausible because if the rise in containment pressure resulting in a Safety Injection had been due to a LOCA, the required classification would be an ALERT.
Additionally a containment pressure increase can result in the Potential Loss of Containment Barrier if the containment spray system falls and a potential loss of only one of the barriers requires an ALERT declaration if the one potential loss is either of the other 2 barriers (RCS or Fuel Clad).
C. Correct, In accordance with EPIP- 1, the conditions for an REP declaration are first met only after both the SI is actuated and the faulted SG pressure has depressurized to less than 675 psig. The correct classification is an NOUE in accordance with EAL 2.7.
D. Incorrect, Plausible because the conditions that required an REP declaration existing only after the SG #3 pressure drops to less than 675 psig is correct and the classification being an ALERT is plausible because if the rise in containment pressure resulting in a Safety Injection had been due to a LOCA the required classification would be an ALERT. Additionally a containment pressure increase can result in the Potential Loss of Containment Barrier if the containment spray system falls and a potential loss of only one of the barriers requires an ALERT declaration if the one potential loss is either of the other 2 barriers (RCS or Fuel Clad).

In the question only 2 of the 4 electric fire pumps are inoperable. This leaves the diesel fire pump and 2 electric fire pumps operable thus the OR- 14.2 entry for HPFP pump lA-A will be a Tracking only (In formation only) entry in accordance with OPDP-8. Also, the SO! requires the four pumps to be selected with and a Train A pump on one Unit and a Train B pump from the other unit selected in A-P AUTO to allow one pump to start immediately and the second pump to start 10 seconds later on an actual fire signal. The current alignment of the control switches provides this starting arrangement.

QUESTIONS REPORT for SRO exam written 03-2013 10CFR55.43.b: 1,2 K/A Match: KJA is matched because the question requires the ability to predict the impact of a low pressure condition on a fire protection pump when another fire pump is already inoperable and the procedure requirements for alignment of the available pumps to mitigate the low pressure condition discovered when testing one of the pumps.
SRO ONLY: Question is SRO only because it requires knowledge of the conditions identified in Part II of the Fire Protection Plan that require action based on the operability status of the of the electric fire pumps and the knowledge of how the conditions will affect the entries into the Tech Spec tracking which is an SRO function.

- A fire is occurring at the Watts Bar Hydro Plant.
- Fire Operations is currently staffed with 2 qualified fire brigade leaders and 6 fire brigade members on site.
- The Shift Manager directs 1 of the fire brigade leaders and 2 fire brigade members to report to the Watts Bar Hydro Plant to provide assistance in extinguishing the fire.
Which ONE of the following completes the statement below in accordance with the Part II Fire Protection Plan?
The onsite Fire Brigade composition A is reduced but remains at or above the minimum required staffing B. is unchanged due to the WB Hydro Station being on the Waifs Bar site C. is less than minimum and requires immediate action to restore the minimum staffing D. is less than minimum but no action is required unless neither of the fire brigade members return within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> DIS TRACTOR ANAL YSIS:
A. Correct, because FPR Part II, 9.1 Fire Brigade Staffing states that the fire brigade is comprised of a fire brigade leader and 4 fire brigade members. There are 4 fire brigade members and a qualified fire brigade leader remaThing on site after the 3 Thdividuals are sent to the Hydro station.
B. Incorrect, Plausible because the with WB hydro on the TVA reservation, none of the fire brigade has left the fl/A reservation. However, the Hydro Station is not on the Nuclear Plant Site and sending personnel to the Hydro station is sending them offsite.
C. Incorrect, SendThg the specified individuals to the fire at the WBH station does not results in the nsite fire brigade staffing being less than the minimum required of a fire brigade leader and four fire brigade members. Plausible because there are references to needthg 5 fire brigade members but the leader is included Th the five and since the action specified is correct if fire brigade staffing was less than minimum.

brigade is comprised of a lire brigade leader and four lire brigade members. The tire brigade shall not include the Shift Manager nor the other members of the minimum shift crew necessary for safe shutdown of the unit, nor any personnel required for other essential functions during a fire emergency Additional support is available when needed through an agreement with a local fire department An Incident Commander s avaiiabie to direct each shift fire brlgade. The incident Commander meets the requirements of a Unit Supervisor, Shift Technical Advisor or Shift Support Supervisor and has sufficient training in or knowledge of plant safety-related systen,sto understand the effects of fire and fire suppressants on safe shutdown capability ic fire brigade composition may be less than the minimum requirements for a period of time not to exceed to hours, in order to accommodate unexpected absence, provided immediate action is taken to fill the required positions The following are examples of emergencies that would prevent the full fire brigade from being available onsite: (a) a life threatening medical emergency, requiring the plant ambulance and EMT responders to leave the site for transport of the patient, and (b) the fire brigade may respond to fires outside the site area, but still on the WA Reservation, to respond to a fire that has the potential to or s affecting the ability for WBN to maintain the ability to safely shut down.

- 24. Given the following:
- While operating at 100% a small break LOCA occurred on Unit 1.
- The operating crew has progressed through the emergency instructions and has just placed RHR in service during performance of ES-i .2, Post LOCA Cooldown and Depressurization.
- An unexpected plant transient results in a YELLOW path to FR-C.3, Saturated Core Cooling, and the SRO makes the transition.
Which ONE of the following completes the statements below?
The basis of FR-C.3 is to jj After entering FR-C.3 a transition to would be directed.
U-A. restore subcooling using ECCS AOI-6, Small Reactor Coolant System Leak B. establish RCS cooling via SGs AOl-6, Small Reactor Coolant System Leak C restore subcooling using ECCS AOI-14, Loss of RHR Shutdown Cooling D. establish RCS cooling via SGs AOI-i4, Loss of RHR Shutdown Cooling wednesday, March 13, 2013 9:16:32 AM 83
QUESTIONS REPORT for SRO exam written 03-2013 DISTRACTOR ANAL YSIS:
A. incorrect, Plausible because the purpose of FR-C.3 is to restore RCS subcooling.
Also because with RCS pressure lower, the leak rate will be reduced and A 01-6 is the AOl used to mitigate an RCS leak when the RHR system is not in service.
B. Incorrect, Plausible because FR-C.2, Degraded Core Cooling, does use the secondary to cool the RCS and because with RCS pressure lower the leak rate will be reduced. A 01-6 is the AOl used to mitigate an RCS leak when the RHR system is not in service.
C. Correct, FR-C.3 attempts to increase the ECCS flow and reduce the loss of primary coolant. Both of these actions will result in restoring a minimum of RCS subcooling.
The WOG background description states Primarily, concern for core cooling arises when the RCS reaches saturation due to a loss of RCS inventory. Without adequate makeup, the continued loss of inventory will cause the core to partially uncover. Guideline FR-C.3 has been developed to address this concern. The operator is instructed to begin safety injection and check for any open RCS vent path in an attempt to stop the loss of RCS inventory. The first step in FR-C.3 directs IF RHR in shutdown cooling mode, THEN GO TO AOl- 14, Loss of RHR Shutdown Cooling.
D. Incorrect, Plausible because FR-C.2, Degraded Core Cooling, does use the secondary to cool the RCS and the transition to A0I-14 is correct.
3.0 OPERATOR ACTIONS NOTE If ECA-32, SGTR nd LOCA SATURATED RECOVERY, is

It requires assessing plant conditions and then selecting a procedure to mitigate, recover, or with which to proceed. One area of SRO level knowledge (with respect to selecting a procedure) is knowledge of the content of the procedure versus knowledge of the procedures overall mitigative strategy or purpose.

- 25. Given the following:
- Unit 1 was operating at 100% power when a LOCA occurs.
- After the operating crew entered 1 -E-1, Loss of Reactor or Secondary Coolant, the OAC reported the following:
- Containment pressure 2.9 psig and rising.
- Containment Spray Pump lA-A started and tripped.
- Containment Spray Pump 1 B-B failed to start.
- The SRO enters 1-FR-Z.1, High Containment Pressure.
- During performance of 1-FR-Z.1, the QAC reports:
- Containment pressure is 1.8 psig and dropping.
- Containment Spray Pump 1 B-B has been started at the breaker and is delivering flow.
- Containment Sump level at 86%.
Assuming all Status trees except CONTAINMENT are GREEN, which ONE of the following identifies the correct procedure usage by the Unit Supervisor?
A. Remain in 1 -FR-Z.1 until a transition is directed, then return to 1 -E-1.
B Remain in 1-FR-Z.1 until a transition is directed, then implement FR-Z.2, Containment Flooding.
C. Immediately transition to FR-Z.2, Containment Flooding, and return to 1-FR-Z.1 when a transition is directed from FR-Z.2.
D. Immediately transition to FR-Z.2, Containment Flooding, and return to 1 -E-1 when a transition is directed from FR-Z.2.
Wednesday, March 13, 2013 9:16:32 AM 86
QUESTIONS REPORT for SRO exam written 03-2013 DIS TRACTOR ANAL YSIS:
A. Incorrect, Plausible because completing FR-Z 1 until a transition is directed is correct and if the containment sump level had been lower, the transition to 1-E-1 would be correct.
B. Correct, After entering an FR due to an ORANGE or RED path the procedure is required to be completed to a point of transition unless a higher priority FR develops. So while the ORANGE condition no longer exist, the FR-Z 1 would be continued even though there is a ORANGE challenge to Containment Flooding until a transition was reached in FR-Z 1 at which time the lower priority FR-Z2 would be implemented.
C. Incorrect, Plausible because it is a common misconception that you would deal with the most severe condition currently existing, which is the challenge to containment flooding due to the sump level since the immediate challenge to containment pressure no longer exists. However, a transition to FR-Z2 will not be made until FR-Z 1 is completed. If the transition was made, it is also normal to transition back to the procedure that was left when the FR is complete which in this case would be FR-Z1.
D. Incorrect, Plausible because a common misconception that you would not need to go back to FR-Z 1 since its orange path is cleared and that you would deal with the most severe condition currently existing. This would incorrectly result in the immediate transition to FR-Z2 and when FR-Z2 is complete, with FR-Z 1 clear, the transition back to 1 -E- 1, while incorrect, is plausible.
T112.04 E. If an ORANGE path is diagnosed. then the remaining Status Trees will be checked. If no RED path exits, then the ORANGE path Function Restoration Instruction will be implemented.
2.4.4 Status Tree Rules of Usage (continued)
F. Once implemented because of any RED or ORANGE path, that Function Restoration Instruction will be performed to completion or to a point of transition UNLESS a higher priority condition develops.
I. As a Function Restoration Instruction is performed, the status of that tree may change. This change does NOT change the priority of an instruction in progress
- 2. If a higher priority condition develops, the instruction in effect should be suspended and the higher priority condition addressed.
G. When no RED or ORANGE path exists, a YELLOW path Function Restoration Instruction can be implemented at the operators discretion.
