ILT41 ONS SRO NRC Examination QUESTION 76 L 76 General Discussion Answer A Discussion Incorrect. First part is plausible because during HPI F/C on RCP is left operating to limit heat input to the RCS. Second part is correct. | |||
Answer B Discussion Incorrect. First part is plausible because during HPI F/C on RCP is left operating to limit heat input to the RCS. Second part is plausible because in other places in the EOP, below 700 degrees, RCP interlocks will not be bypassed.. Example: LOHT tab If there is no heat transfer and SCM> 0 degrees then 1 RCP is started but interlocks are not bypassed. | |||
Answer C Discussion Correct. In accordance with EOP ICC tab steps 39 and 40, 1RCP/loop will be started and RCP starting interlocks will be bypassed as required. | |||
Answer D Discussion Incorrect. First part is correct. Second part is plausible because in other places in the EOP, below 700 degrees, RCP interlocks will not be bypassed.. Example: LOHT tab If there is no heat transfer and SCM> 0 degrees then I RCP is started but interlocks are not bypassed. | |||

ILT41 ONS SRO NRC Examination QUESTION 78 General Discussion Answer A Discussion Correct. Once you make your way to the correct section of AP/26 it will direct securing all LPI pumps in an effort to determine the location and isolability of the leak. If securing the pumps do not change the leak rate then they will be restarted. | |||
Answer B Discussion Incorrect. First part is correct. Second part is plausible since the current SFC alignment in the refueling mode provides for taking a suction off the fuel transfer canal via the decay heat drop line and discharging to the SFP. That alignment must be secured prior to closing SF-l and 2 to prevent pumping FTC to SFP however it is the B SF pump being used in this alignment and not the LPI pumps. | |||
Answer C Discussion Incorrect. Plausible since the B SFC Pump is being used in the Refueling Mode alignment and securing the pump and monitoring leak iate could help determine if the source of the leak is on the discharge of SFC pump. Since the Fuel Transfer Canal is full, securing the pump is plausible. | |||
Additionally, this action is actually directed by AP/26 although it is a later action after transferring to the condition specific section of the AP. It is the LPI pumps that are initially secured. | |||
Answer D Discussion rrect. Plausible since the SFC pumps are secured later in AP/26 prior to closing SF-I and 2 to prevent pumping FTC to SFP. | |||
Basis for meeting the KA Requires knowledge of actions taken in AP/26 based on a decreasing fuel transfer canal and the ability to interpret the results of those actions to deterntine location and isolability of Fuel Transfer Canal leak. | |||
Basis for Hi Cog Basis for SRO only In accordance with Rev. 1 of Clarification Guidance for SRO-only Questions: | |||
This first part of this question requires detailed knowledge of specific procedure steps in AP/26. Knowledge of these steps are used to select which section of the procedure is to be performed. There are several sections of Subsequent Actions that could be performed based on the conditions requiring entry into the AP and using knowledge of the entry conditions and assessing the different sections of Subsequent actions is | |||
[required to determine the appropriate steps to perform. Additionally, this question requires detailed knowledge of specific steps that need to be taken prior to transfer to section 4D. In this specific case, the LPI pumps are secured to assess the impact on the decreasing fuel transfer canal level. In this situation it is after these steps are performed that you make the transfer to section 4D which will direct stopping the SF Pump. This path through the AP means that to get to the appropriate actions you must assess plant conditions and determine a section of the procedure with which to proceed. | |||
This question cannot be answered bases solely on systems knowledge since when in MODE 6 with fuel transfer canal full it would be normal to have LPI pumps running AND the B Spent Fuel Cooling pump aligned in the Refueling Cooling mode. Also, neither reason given for securing pumps would eliminate either answer based on system knowledge. | |||
This question cannot be answered bases solely on knowledge of entry conditions. | |||
None of the operator actions are Immediate Operator Actions of the AP. | |||
The knowledge needed is more detail than just the major mitigation strategy of the AP. | |||

ILT41 ONS SRO NRC Examination QUEST..iON 79 79 General Discussion Answer A Discussion Incorrect. First part is plausible because if the loss of SCM was not due to heating up this would be correct. Second part is plausible because Rule 2 would still be initiated in this case. | |||
Answer B Discussion Incorrect. First part is plausible because if the loss of SCM was not due to heating up this would be correct. Second part is plausible because this would be performed if HPI was degraded. | |||
Answer C Discussion Correct. Per a note in the LOHT tab Transfer to LOSCM tab is NOT required if RCS heats to the point where core SCM = 0°F.. Per the LOHT tab if the RCS heats up to the point where core SCM = 0 degrees then Rule 4 will be initiated. | |||
Answer D Discussion Incorrect. First part is correct. Second part is plausible because this would be done if HPI F/C was not adequate. | |||

ILT41 ONS SRO NRC Examination QUESTION 80 80 General Discussion Answer A Discusson Correct. 3DIC OOS will result in entering TS 3.8.8 Conditions C. KVIA and KVIB have shorter completion times due to powering the ES Voters. | |||
Answer B Discussion Incorrect: : First part is Correct. Second part is plausible since SK and SL breakers protective relaying is singled out in the electrical specs as unique. It is unique because unit ls DIC and DID panelboards provide power to these breakers that all 3 units rely on. The fact that the power for SK and SL breakers comes from a units power panelboards and is singled out as unique in the electrical specs combine to make this a plausible distractor since Condition F is itself unique for other reasons. Additionally, the breakers are getting power from the c and d strings of panelboards however it is from the DC panelboards instead of the AC panelboards. | |||
Answer C Discussion Incorrect. First part is plausible because it would be correct if it were IDIC. Second aprt is correct. | |||
Answer D Discussion --__________ | |||
Incorrect. First part is plausible because it would be correct if it were 1DIC. Second part is plausible since SK and SL breakers protective relaying is singled out in the electrical specs as unique. It is unique because unit 1 s DIC and DID panelboards provide power to these breakers that all 3 units rely on. The fact that the power for SK and SL breakeis comes from a units power panelboards and is singled out as unique in the electrical specs combine to make this a plausible distractor since Condition F is itself unique for other reasons. Additionally, the breakers are getting power from the c and d strings of panelboards however it is from the DC panelboards instead of the AC panelboards. | |||

ILT41 ONS SRO NRC Examination QUESTION 83 General Discussion Answer A Discussion Correct. ICCM Train A feeds Pzr level I and 2. A loss of power to 1A ICCM Train will cause Pzr Level 2 to fail low and cause 1HP-120 to fully open. The operator must take manual control of 1HP-120 to prevent the Pzr from exceeding the TS limit on level. TSB 3.4.9 states: If the level limits were exceeded prior to a transient that creates a large pressurizer insurge volume, the maximum RCS pressure could exceed the design Safety Limit (SL) of 2750 psig. | |||

ILT41 ONS SRO NRC Examination QUESTION 93 93 General Discussion Answer A Discussion Incorrect. Plausible since there are several conditions in SLC 16.11.3 that provide for allowing a short < ihr planned outage of required RIAs or RIA components without having to enter the Condition for that RIA or component being inoperable. Therefore referring to the wrong condition or based on sight recognition of the 1 hour controlled outage, attempting to answer without looking up the correct condtions could result in making this choice. | |||
Answer B Discussion | |||
[ect. RIA-54 being inoperable results in entry into Condition B. Required Action B.1 requires using Table 16.11.3-ito determine additional Conditions that apply. The table for RIA-54 refers to Condition F. | |||
Answer C Discussion Incorrect. Condition B is correct. Condition H is plausible since it would be correct for the Sample Flow Monitor associated with RIA-54 being inoperable (per Table 16.11.3-1). | |||
Answer D Discussion Incorrect. Conditions B and F are correct and Condition H is plausible since it would be correct for the Sample Flow Monitor associated with RIA-54 being inoperable (per Table 16.11.3-1). | |||

ILT41 ONS SRO NRC Examination QUESTION 96 L 96 General Discussion Answer A Discussion Incorrect: SR 3.0.2 allows for 25% extension of the interval specified as the frequency. This answer would be correct without the 25% extension applied since SR 3.4.8.1 has a 12 hour frequency. | |||
Answer B Discussion Correct: SR 3.0.2 allows for 25% extension of the interval specified as the frequency. SR 3.4.8.1 has a 12 hour frequency therefore applying the 25% extension results in 15 hours which is 1200 on 12-2. | |||
Answer C Discussion Incorrect: This would be correct if the surveillance was a SLC requirement and not a TS requirement. SLC 16.2.7 says that SLC frequencies get a 50% extension which would be 18 hours which is 2100 on 12-2. | |||

ILT41 ONS SRO NRC Examination QUESTION 97 97 Genera! Discussion Answer A Discussion Correct. 1HP-939/940 provide a flow path from the LDST outlet to the RBES. These valves are opened to prevent the HPI pump recilt flow during piggyback from causing HPI relief valves from opening. If opened this would cause high dose rates in the AB. | |||
Answer B Discussion Incorrect. First part is correct. Second part is plausible a flow path to the RBES is aligned to provide for post LOCA Boron Dilution. However this is not the correct flow path. | |||
Answer C Discussion Incorrect. Plausible if the candidate has the misconception that the valves are used to ensure an HPI pump recirc flow path back to the LDST. | |||
Second part is correct. | |||
Answer D Discussion Incorrect. Plausible if the candidate has the misconception that the valves are used to ensure an HPI pump recir flow path back to the LDST. | |||
Second part is plausible because they do route letdown flow to the RBES which would relive letdown pressure however they are on the outlet of the LDST. | |||

ILT41 ONS SRO NRC Examination QUESTION 76 L 76 General Discussion Answer A Discussion Incorrect. First part is plausible because during HPI F/C on RCP is left operating to limit heat input to the RCS. Second part is correct.
Answer B Discussion Incorrect. First part is plausible because during HPI F/C on RCP is left operating to limit heat input to the RCS. Second part is plausible because in other places in the EOP, below 700 degrees, RCP interlocks will not be bypassed.. Example: LOHT tab If there is no heat transfer and SCM> 0 degrees then 1 RCP is started but interlocks are not bypassed.
Answer C Discussion Correct. In accordance with EOP ICC tab steps 39 and 40, 1RCP/loop will be started and RCP starting interlocks will be bypassed as required.
Answer D Discussion Incorrect. First part is correct. Second part is plausible because in other places in the EOP, below 700 degrees, RCP interlocks will not be bypassed.. Example: LOHT tab If there is no heat transfer and SCM> 0 degrees then I RCP is started but interlocks are not bypassed.
Basis for meeting the KA Question requires knowledge of the ICC tab which was entered as a result of Pzr vapor space accident.
Basis for Hi Cog Basis for SRO only In accordance with Clarification Guidance for SRO-only Questions, this question requires assessing plant conditions (RCS temp) and selecting a section of a procedure with which to proceed (starting RCPs). Also requires detailed knowledge of the content of the procedure specific to the section being performed (how many RCPs will be started and will interlocks be bypassed).
The question is not systems knowledge.
The question is not Immediate Operator Actions.
The question cannot be answered from knowledge of entry conditions.
This question requires more specific knowledge than knowledge of the major mitigation strategy of the procedure.

ILT41 ONS SRO NRC Examination QUESTION 78 General Discussion Answer A Discussion Correct. Once you make your way to the correct section of AP/26 it will direct securing all LPI pumps in an effort to determine the location and isolability of the leak. If securing the pumps do not change the leak rate then they will be restarted.
Answer B Discussion Incorrect. First part is correct. Second part is plausible since the current SFC alignment in the refueling mode provides for taking a suction off the fuel transfer canal via the decay heat drop line and discharging to the SFP. That alignment must be secured prior to closing SF-l and 2 to prevent pumping FTC to SFP however it is the B SF pump being used in this alignment and not the LPI pumps.
Answer C Discussion Incorrect. Plausible since the B SFC Pump is being used in the Refueling Mode alignment and securing the pump and monitoring leak iate could help determine if the source of the leak is on the discharge of SFC pump. Since the Fuel Transfer Canal is full, securing the pump is plausible.
Additionally, this action is actually directed by AP/26 although it is a later action after transferring to the condition specific section of the AP. It is the LPI pumps that are initially secured.
Answer D Discussion rrect. Plausible since the SFC pumps are secured later in AP/26 prior to closing SF-I and 2 to prevent pumping FTC to SFP.
Basis for meeting the KA Requires knowledge of actions taken in AP/26 based on a decreasing fuel transfer canal and the ability to interpret the results of those actions to deterntine location and isolability of Fuel Transfer Canal leak.
Basis for Hi Cog Basis for SRO only In accordance with Rev. 1 of Clarification Guidance for SRO-only Questions:
This first part of this question requires detailed knowledge of specific procedure steps in AP/26. Knowledge of these steps are used to select which section of the procedure is to be performed. There are several sections of Subsequent Actions that could be performed based on the conditions requiring entry into the AP and using knowledge of the entry conditions and assessing the different sections of Subsequent actions is
[required to determine the appropriate steps to perform. Additionally, this question requires detailed knowledge of specific steps that need to be taken prior to transfer to section 4D. In this specific case, the LPI pumps are secured to assess the impact on the decreasing fuel transfer canal level. In this situation it is after these steps are performed that you make the transfer to section 4D which will direct stopping the SF Pump. This path through the AP means that to get to the appropriate actions you must assess plant conditions and determine a section of the procedure with which to proceed.
This question cannot be answered bases solely on systems knowledge since when in MODE 6 with fuel transfer canal full it would be normal to have LPI pumps running AND the B Spent Fuel Cooling pump aligned in the Refueling Cooling mode. Also, neither reason given for securing pumps would eliminate either answer based on system knowledge.
This question cannot be answered bases solely on knowledge of entry conditions.
None of the operator actions are Immediate Operator Actions of the AP.
The knowledge needed is more detail than just the major mitigation strategy of the AP.

ILT41 ONS SRO NRC Examination QUESTION 96 L 96 General Discussion Answer A Discussion Incorrect: SR 3.0.2 allows for 25% extension of the interval specified as the frequency. This answer would be correct without the 25% extension applied since SR 3.4.8.1 has a 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> frequency.
Answer B Discussion Correct: SR 3.0.2 allows for 25% extension of the interval specified as the frequency. SR 3.4.8.1 has a 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> frequency therefore applying the 25% extension results in 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> which is 1200 on 12-2.
Answer C Discussion Incorrect: This would be correct if the surveillance was a SLC requirement and not a TS requirement. SLC 16.2.7 says that SLC frequencies get a 50% extension which would be 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> which is 2100 on 12-2.

ILT41 ONS SRO NRC Examination QUESTION 97 97 Genera! Discussion Answer A Discussion Correct. 1HP-939/940 provide a flow path from the LDST outlet to the RBES. These valves are opened to prevent the HPI pump recilt flow during piggyback from causing HPI relief valves from opening. If opened this would cause high dose rates in the AB.
Answer B Discussion Incorrect. First part is correct. Second part is plausible a flow path to the RBES is aligned to provide for post LOCA Boron Dilution. However this is not the correct flow path.
Answer C Discussion Incorrect. Plausible if the candidate has the misconception that the valves are used to ensure an HPI pump recirc flow path back to the LDST.
Second part is correct.
Answer D Discussion Incorrect. Plausible if the candidate has the misconception that the valves are used to ensure an HPI pump recir flow path back to the LDST.
Second part is plausible because they do route letdown flow to the RBES which would relive letdown pressure however they are on the outlet of the LDST.

ILT41 ONS SRO NRC Examination QUESTION 98 98 General Discussion Answer A Discussion CORRECT: Plant conditions indicate a LOCA is occurring. This requires EDLs to be in effect. 5 rem is the maximum dose that could be received under EDLs for performing Time Critical Tasks.
Answer B Discussion Incorrect: First part is correct. Second part is incorrect. Plausible because 25 rem is the limit for lifesaving activities.
Answer C Discussion Incorrect: First part is incorrect. Plausible if they miss diagnose a MSLB. Second part is incorrect. Plausible in that 2 rem is the normal administrative limit.
Answer D Discussion Incorrect: First part is incorrect. Plausible if they miss diagnose a MSLB. Second part is incorrect. Plausible because 10 rem is the maximum allowed dose for protecting property. 25 rem is the limit for lifesaving activities.

FOR REVIEW ONLY DO NOT DISTRIBUTE B
ILT41 ONS SRO NRC Examination QUESTION 99 99j General Discussion Answer A Discussion Incorrect. First part is correct. Second part is plausible because the candidate may have the misconception that BWST does not have adequate inventory to cooldown to LPI.
Answer B Discussion Correct. For a TBF, feeding SGs with raw water from SSF ASW or Station ASW is preferred over HPI forced cooling. HPI F/C is not preferred since once the BWST is depleted, water in the RBES is not expected to be available due to unavailability of LPSW for cooling.
Answer C Discussion Incorrect. First part is plausible because HPI F/C is normally preferred over using SSF ASW. Second part is plausible because the candidate may have the misconception that the BWST does not have adequate inventory to cooldown to LPI.
Answer D Discussion ncorrect First part is plausible because HPI F/C is normally preferred over using SSF ASW. Second part is plausible because feeding raw lake water into the SGs is bad but is not the reason in this case.
