FOR REVIEW ONLY - DO NOT DISTRIBUTE 2012 MNS SRO NRC Examination QUESTION 76 A

76 General Discussion Per SLC 16.9.11, both the BAT and FWST shall be operable in Modes 1-3 and Mode 4 > 300 F. The Tech Spec required boron concentration for the FWST to be operable is 2675 - 2875 PPM. Per fhte SLC basis, the FWST limits on boron ensure a containment sump pH value of 7.5-9.5, which minimiizes the effect of chloride stress corrosion and caustic stress corrosion. Excessive boron results in a lower pH condition, therefore, the effect of chloride stress corrosion is increased. Low boron concentration (initial conditions in this question) results in a higher pH condition, increasing the effect of caustic stress corrosion.

According to the basis of Tech 3.5.4 (RWST): The upper limit on boron concentration as listed in the COLR is used to determine the maximum allowable time to switch to hot leg recirculation following a LOCA. The purpose of switching from cold leg to hot leg injection is to avoid boron precipitation in the core following the accident. EP/1/A/5000/E-1, step 20 addresses transfer to Hot Leg Recirc (HLR) 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after event initiation.

Per the basis document:

After six hours after event has initiated, boric acid concentrations could approach the solubility limit in the reactor vessel/core region following a double-ended cold leg guillotine break. The time established by this analysis would preclude boron precipitation from the boric acid solution that could potentially hinder core cooling.

If FWST boron is higher than the assumptions in the accident analysis, the solubility limit in the reactor vessel/core region could be reached sooner than 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

Answer A Discussion CORRECT: See explanation above.

Answer B Discussion INCORRECT: See explanation above.

First part correct.

Second part is plausible because it would be correct if the boron concentration were out of spec high. This is plausible if the applicant reverses the effect boron concentration has on pH, or thinks the current boron concentration is out of spec high.

Answer C Discussion INCORRECT: See explanation above.

First part is plausible because SLC 16.9.14 (Borated Water Sources - Shutdow) only requires one of the two tanks to be operable. This SLC is applicable in Mode 4 (< 300 F) and Mode 5 and 6.

Second part is correct.

Answer D Discussion INCORRECT. See explanation above.

PLAUSIBLE:

First part is plausible because SLC 16.9.14 (Borated Water Sources - Shutdow) only requires one of the two tanks to be operable. This SLC is applicable in Mede 4 (< 300 F) and Mode 5 and 6.

Second part is plausible if the applicant reverses the effect boron concentration has on pH, or concludes the current boron concentration is out of spec high.

Basis for meeting the KA This question requires the applicant to predict a possible impact of an out of spec FWST boron concentration (SLC 16.9.11 basis). While an improper FWST boron concentration does not directly impact the CVCS, it does affect the boration flowpath function of the CVCS to mitigate a LOCA.

Basis for Hi Cog Basis for SRO only This question meets the following criteria for an SRO only question as described in the "Clarification Guidance for SRO-only Questions (Rev 1 dated 03/11/2010)" under the Screening Criteria for question linked to 10CFR55.43(b)(2) (Tech Specs):

77 General Discussion Given the plant conditions the applicant should determine a loss of subcooling (based on NCS pressure and CET temperature), no NCPs running (due to Loss of Offsite Power) and a Red Path on the Core Cooling safety function (> 700 °F and < 39% reactor vessel level with NCPs off).

Per RP/0/A/5700/000, the correct classification is General Emergency based on 4.1.G.2. (Loss of Any Two Barriers AND Potential Loss of the Third)

Containment Barrier: 1 points (Due to Core Cooling RED path indicated for greater than 15 minutes)

NCS Barrier: 5 points (Due to Loss of Subcooling) - LOSS Fuel Clad Barrier: 5 points (Due to Core Cooling RED path) - LOSS TOTAL POINTS = 11 (General Emergency)

If the containment barrer was also affected, the classification was be upgraded to a General Emergency.

Answer A Discussion INCORRECT. See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant does not include the points for a RED path on Core Cooling for greater than 15 minutes.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Plausible if the applicant fails to consider a loss of subcooling for the NCS barrier or incorrectly determines Core Cooling safety function is ORANGE.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Plausible if the applicant believes the loss of power to the 1B train of Containment isolation valves means Containment Isolation is incomplete, resulting in a loss of the containment barrier.

Answer D Discussion CORRECT: See explanation above.

78 General Discussion The MNS, the Containment Air Return System (VX) is associated with Containment Cooling. During a LOCA, the CARS is design to rapidly return air from Upper Containment to Lower Containment for continued cooling by the Ice Condensers.

In accordance with Tech Spec 3.8.1 (AC Sources - Operating), due to the INOPERABILITY of the 1A DG, the redundant features associated with the 1B VX Train (which is already INOPERABLE) must also be declared INOPERABLE. This means that the 1A VX Train is also INOPERABLE. Tech Spec 3.8.1 requires that the 1A DG or the 1B VX Train be restored to OPERABLE within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or the unit 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 />.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant incorrectly applies the action time starting with the inoperability of the 1B VX Train instead of the time of the 1A DG inoperability.

Answer B Discussion CORRECT: See explanation above.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant does not recall the 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> time limitation contained in Tech Spec 3.8.1 and applies the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> time for the DG or the VX Train to the original operability time of the 1B VX Train.

79 General Discussion With all SGs < 12% WR (all dry), FR-H.1, Enclosure 8, steps 22-24 direct that flow be established to one intact SG at minimum flow to minimize thermal shock to the SG.

The minimum rate depends on the status of the Core Exit T/Cs (CETs). If CETs are stable or going down, the SGs are fed at the minimum rate that obtains SG WR Level response or feed flow indication going up. If CETs are going up, the minimum rate is that needed to lower CETs. In the scenario given, the CETs are going up, so a feed rate to turn the temperature is needed.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

First part is plausible since the feedwater flow would be correct for the condition where core exit thermocouples are stable or decreasing.

Second part is plausible because overcooling the NC system is stated in FR-H.1 as a concern in multiple notes and cautions concerning initiating feed to a dry generator. And, reactor vessel nozzle protection is plausible since it is a component that interfaces with the SGs.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

First part is plausible since the feedwater flow would be correct for the condition where core exit thermocouples are stable or decreasing.

Second part is correct.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

First part is correct.

Second part is plausible because overcooling the NC system is stated in FR-H.1 as a concern in multiple notes and cautions concerning initiating feed to a dry generator. And, reactor vessel nozzle protection is plausible since it is a component that interfaces with the SGs.

Answer D Discussion CORRECT: See explanation above.

Basis for meeting the KA The KA is matched because the operator must demonstrate the ability to interpret and execute procedure steps to restore Main Feedwater to the SGs during a Loss of Secondary Heat Sink. Specifically he must demonstrate the ability to recognize plant conditions and take the procedural actions accordingly.

Basis for Hi Cog This is a hi cog question because it involves a level of analysis of given situation. This involves a multi-part mental process where the applicant must evaluate the indications given and determine its meaning related to the scenario given and determine a course of action and the basis for that action.

Basis for SRO only This question meets the following criteria for an SRO only question as described in the Clarification Guidance for SRO-only Questions Rev 1 dated 03/11/2010 for screening questions linked to 10CFR55.43(b)(5) (Assessment and selection of procedures):

1) The question can NOT be answered solely by knowing systems knowledge.

This is not systems knowledge. It is detailed knowledge of the steps in FR-H.1 and how to implement them.

2) The question can NOT be answered by knowing immediate operator actions.

There are NO immediate actions associated with the FR-H.1.

3) The question can NOT be answered solely by knowing entry conditions for AOP or direct entry conditions for EOPs.
4) The question can NOT be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of the procedure.

The first part of this question requires detailed knowledge of procedure step requirements. The second part of this question requires detailed knowledge of a note Enclosure 8 of FR-H.1.

80 General Discussion Per Tech Spec 3.8.3 basis, Each DG has an air start system with adequate capacity for five successive start attempts on the DG without recharging the air start receiver(s). Per Condition D Basis, DG starting air system normal alignment allows air from both receivers to enter both left and right starting air headers. Therefore, with one receiver isolated, both left and right starting air headers will be supplied from the remaining receiver. With the degraded receiver isolated and the remaining receiver @ 210 psig, the capacity for 5 starts exists. Therefore, the DG is still operable. If starting air pressure to the receiver tank cannot be restored within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the DG would then be declared inoperable.

Answer A Discussion INCORRECT: See explanation above.

First part is correct.

Second part is plausible if the applicant fails to realize that one starting air receiver tank will supply both left and right starting air headers and think that starting air capacity has been reduced.

Answer B Discussion CORRECT: See explanation above.

Answer C Discussion INCORRECT: See explanation above.

First part is plausible because other conditions associated with starting air would render the D/G inoperable right away (e.g. both receiver tanks pressures < 210 psig). Additionally if starting air pressure couldnt be restored within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the DG would be declared inoperable for this condition.

Second part is plausible if the applicant concludes that starting air capacity has been reduced with the loss of one of the receiver tanks.

Answer D Discussion INCORRECT: See explanation above.

First part is plausible because other conditions associated with starting air would render the D/G inoperable right away (e.g. both receiver tanks pressures < 210 psig). Additionally if starting air pressure couldnt be restored within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the DG would be declared inoperable for this condition.

Second part is correct.

TS 3.8.3 (DG Fuel Oil and Starting Air)

Basis for meeting the KA The KA is matched because the question concerns annunciators that indicate the malfunctioning Starting Air system (VG). The applicant must determine that Tech Spec 3.8.3 is applicable. The OAC alarm gives indications that only one of two starting air tanks is losing pressure. This requires the applicant to "interpret the significance" of the alarms to determine the operability of the DG and current capacity of the Starting Air system for the 1A DG.

Basis for Hi Cog This is a higher cognitive level question because it requires multiple mental steps. The applicant must first analyze the information to determine that the low starting air pressure is an entry condition for Tech Specs. The applicant must then recall from memory that one Starting Air Receiver tank is all that is needed for the DG to meet its intended function (one tank can still provide 5 start attempts, therefore the DG is still considered operable).

FOR REVIEW ONLY - DO NOT DISTRIBUTE 2012 MNS SRO NRC Examination QUESTION 81 D

81 General Discussion AP-14, step 13.d.4, checks to determine is AFD is within Tech Spec limits. If Tech Spec AFD limits are exceeded and reactor power is greater than 50%, the operators are directed to trip the reactor and transition to E-0. Although a logical action would be to reduce power to less than 50%, restoring AFD to within limits in an acceptable amount of time to prevent fuel damage without the use of the controls rods is not likely to be successful. Therefore, the reactor is tripped to prevent axial peaking factors from causing fuel damage.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant concludes that Tech Spec 3.2.4 applies since QPTR limits have been exceeded. If that were the case and the applicant misapplies the spec, they would determine that power should be reduce by 3% for each 1% that QPTR is outside the limit (1.02).

They would therefore conclude that power should be reduced by 9% (to 81%) to comply with the spec.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because if AFD had NOT exceeded the Tech Spec limits, this would be the correct answer.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because if AFD had not exceeded the Tech Spec limits, this would be a correct answer.

Answer D Discussion CORRECT: See explanation above.

84 General Discussion In accordance with AP-08, if an NC pump must be stopped reactor must be tripped if the unit is operating in Mode 1 or 2 and the NC can not be stopped until power is less than 5%.

If the NC pump trip criteria has not yet been exceeded but it is determined that the NCP still needs to be stopped, AP-08 directs performing a unit shutdown in accordance with OP/1/A/6100/003 (Controlling Procedure for Unit Operation) or AP-04 (Rapid Downpower). The NCP is then stopped after all rods are inserted and the Reactor Trip breakers are open.

Answer A Discussion CORRECT: See explanation above.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because tripping the Reactor first is the correct action. Stopping the NCP when power is less than 10% is plausible since the NC low flow trips are defeated when less than 10% power (P-10). It is also plausible for the applicant to believe that the reactor would be at greater than 5% after a trip since initial decay heat load immediately after a trip is approximately 7%.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because the NC pump is stopped when power is less than 5%. However, the reactor is tripped instead of performing a Rapid Downpower.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because stopping the NCP when power is less than 10% is reasonable since the NC low flow trips are defeated when less than 10% power (P-10).

IF AT ANY TIME it is known that a charging pump will not be restored prior to Pzr level reaching 20%, THEN evaluate starting Standby Makeup pump PER Enclosure 3 (Standby Makeup Pump Startup).

The MINIMUM seal injection flow required by AP-12 is 6 GPM. Normal minimum seal injection flow for starting a pump in OP/1/A/6150/002A (NC Pump Operation) is 8 GPM.

Answer A Discussion CORRECT: See explanation above.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Part 1 is plausible because in 36 minutes Pressurizer level would be 4% which is the minimum PZR level used throughout the APs and EOPs as a criteria for tripping the Reactor and going to E-0. Additionally, one of the reasons cited in the basis for Step 18 is that if a Reactor trip is subsequently required (possibly due to placing the Standby Makeup Pump in service) PZR level will initially be high enough that the shrink caused by the Reactor trip will not reduce PZR level below 4% which would require Safety Injection to be initiated.

Part 2 is correct.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Part 1 is correct.

Part 2 is plausible because this is the minimum seal injection flow required by OP/1/A/6150/002A (NC Pump Operation) to start a NCP.

Additionally, this is the minimum seal injection flow during NORMAL operation.

Answer D Discussion INCORRECT: See explanation above.

Additionally, this is the minimum seal injection flow during NORMAL operation.

Basis for meeting the KA The KA is matched because a loss of both charging pumps occurs, resulting an a loss of reactor coolant makeup and the applicant must determine how long it will take to reach a specific PZR level associated with required procedure step actions.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. The applicant must first recall the PZR level that requires evaluation for placing the Standby Makeup Pump in service. The applicant must then calculate the amount of time, based on current PZR level and rate of decrease that it will take before PZR reaches the minimum level.

86 General Discussion For the conditions given, the crew would implement EG/1/A/MSAM/SACRG1 (Severe Accident Control Room Guideline Initial Response).

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant does not recall that they were directed to monitor CSFSTs prior to the transition from E-0 to FR-S.1. If they continued to the end of FR-S.1, they would be directed to "return to procedure and step in effect". This would send them back to E-0 where they would continue until directed to monitor CSFSTs and would then transition to FR-C.1 based on a RED path condition.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because in the RNO for the next step the crew is permitted to implement the actions of other Critical Safety Functions that apply provided they do not cool down the NC system or otherwise add positive reactivity.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because applicants are trained that, with the exception of ECA-0.0, FR-S.1 takes priority over all other procedures. It is therefore plausible for the applicant to conclude that they should remain in FR-S.1 until the entry conditions for FR-S.1 are no longer met.

Answer D Discussion CORRECT: See explanation above.

Basis for meeting the KA The KA is matched because the applicant is given a set of conditions where entry conditions for two FRPs are met. Based on a plant conditions and a knowledge of the procedure, the applicant must determine how the FRPs should be implemented.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. The applicant must analyze the conditions given to determine the condition of the plant. The applicant must then recall from memory the procedural requirements from FR-S.1 to determine which procedure must be implemented.

Basis for SRO only This question meets the following criteria for an SRO only question as described in the Clarification Guidance for SRO-only Questions Rev 1 dated 03/11/2010 for screening questions linked to 10CFR55.43(b)(5) (Assessment and selection of procedures):

AP-15 directs the Operators to ensure that the effected DC bus is swapped to an alternate source prior to bus voltage reaching 107 VDC.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Part 1 is plausible because Tech Spec 3.8.6 requires that the surveillance to verify battery cell parameters be performed any time the battery is discharged to less than 110VDC.

Part 2 is correct.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Part 1 is plausible because Tech Spec 3.8.6 requires that the surveillance to verify battery cell parameters be performed any time the battery is discharged to less than 110VDC.

Basis for meeting the KA MNS does not have the ability to monitor or trend DC Bus voltage in the Control Room. For the purposes of this question, the trending of DC Bus voltage is performed by a NEO in the field who reports those voltages to the Control Room. The Control Room staff is tasked with tracking that trend and taking appropriate actions based on knowledge of AP-15 (Control Room Reference Material). Therefore, the KA is matched.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. The first part of the question requires the applicant to recall from memory the voltage at which the inverter must be swapped to an alternate power supply and then they must calculate the time to reach that voltage based on the current battery voltage and the rate of decrease in terminal voltage.

Basis for SRO only This question meets the following criteria for an SRO only question as described in the Clarification Guidance for SRO-only Questions Rev 1 dated 03/11/2010 for screening questions linked to 10CFR55.43(b)(5) (Assessment and selection of procedures):

Part 1 of this question is RO level knowledge. Part 2 of this question can only be answered by having knowledge of AP-15 (Loss of Vital or Aux Control Power).

2) The question can NOT be answered by knowing immediate operator actions.

There are NO immediate actions associated with AP-15.

3) The question can NOT be answered solely by knowing entry conditions for AOP or direct entry conditions for EOPs.

Neither part of this question is associated with AP-15 entry conditions. Both are related to information contained in AP-15 Enclosure 1 (Response to Degraded DC Bus Voltage).

Answer A Discussion CORRECT: See explanation above.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because in most cases, transition to FR-Z.1 would be required. And, for the conditions given if a transition to FR-Z.1 was made, starting one NS pump would be the correct action.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because remaining in Enclosure 5 is the correct procedure. Aligning one train of ND Aux Spray is plausible because that is the action to be taken after ONE NS pump is running in FR-Z.1 if Containment pressure is greater than 15 PSIG.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because because in most cases, transition to FR-Z.1 would be required. Starting ONE NS pump is the correct action when in FR-Z.1. Aligning one train of ND Aux Spray is plausible because that is the action to be taken after ONE NS pump is running in FR-Z.1 if Containment pressure is greater than 15 PSIG.

Basis for meeting the KA The KA is matched because the applicant must have knowledge of the "basis" for prioritizing the implementation of procedures associated with operation of the NS system.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step.

90 General Discussion Tech Spec 3.9.7 is applicable: 1. During CORE ALTERATIONS, except during latching and unlatching control rod drive shafts, and 2. during movement of irradiated fuel assemblies within containment.

The basis for Tech Spec 3.9.7 is to ensure sufficient water necessary to retain iodine fission product activity in the water in the event of a fuel handling accident. Sufficient iodine activity would be retained to limit offsite doses from the accident to within 10 CFR 50.67 limits, Answer A Discussion INCORRECT.

PLAUSIBLE:

First part incorrect. Plausible because another refueling Tech Spec is applicable only during movement of irradiated fuel assemblies (TS 3.9.4 -

Containmet Penetrations) and the applicant may confuse the two. Additionally, since the TS basis deals with damaged fuel and the release of iodine, the applicant may conclude that there is no water level limit or there is another Tech Spec that addresses core alterations.

Second part correct.

Answer B Discussion INCORRECT PLAUSIBLE:

First part incorrect. Plausible because another refueling Tech Spec is applicable only during movement of irradiate fuel assemblies (TS 3.9.4 -

Containmet Penetrations) and the applicant may confuse the two. Additionally, since the TS basis deals with damaged fuel and the release of iodine, the applicant may conclude that there is no water level limit during core alterations.

Second part is incorrect. Plausible because there are dose concerns to refueling personnel on site during fuel movement. The magnitude of the dose concerns would be related to the refueling cavity water level.

Answer C Discussion CORRECT. See explanation above.

Answer D Discussion INCORRECT PLAUSIBLE First part correct.

Second part is incorrect. Plausible because there are dose concerns to refueling personnel on site during fuel movement. The magnitude of the dose concerns would be related to the refueling cavity water level.

Basis for meeting the KA The water level requirements in Tech Spec 3.9.7 will ensure the radiological consequences of a postulated fuel handling accident are within the limits of the accident analysis. (036 Fuel Handling Incidents).

The basis for the water level requirement relates to the magnitude of the potential radioactive releases (and offsite dose concerns) if refueling cavity water level was not high enough..

FOR REVIEW ONLY - DO NOT DISTRIBUTE 2012 MNS SRO NRC Examination QUESTION 91 C

91 General Discussion The Liquid Waste Release (LWR) permit is designed to prevent an UNCONTROLLED release of radioactive materials to the environment in liquid effluents. The two pieces of this control are: 1. ensuring adequate dilution of the liquid and 0EMF40(L) Trip setpoints. The amount of dilution needed is based on the activity of the tank to be released. The dilution includes a limit on the release rate and the number of RC pumps that need to be running. Minimum dilution flow is assured by an interlock terminating waste liquid releases if the number of RC Pumps running falls below the number of pumps required for dilution.

Since more than one liquid waste release can occur at one time, the LWR states the number of pumps needed for this release and also the total number for all concurrent releases. The SRO must verify the required number of RC pumps are running for all concurrent releases. If less than the required number of RC pumps is running, the LWR cannot be approved.

Per OP-MC-WE-RLR lesson, section 2.1, a limiting release rate is calculated and shown as "Allowable Release Rate" on the LWR. This is based on the activity present in the tank. Also printed on the LWR is the Recommended Release Rate. The Recommended Release Rate is either the Allowable Release Rate or the system maximum, whichever is lower. The system maximum for the WMT pump is 120 gpm. In this case, if the WMT is released at 120 gpm, it is possible the limits of SLC 16.11.1 (Liquid Effluents - Concentration) would be exceeded.

When reviewing the LWR, the SRO is not expected to know the exact Trip setpoint values of the EMF, just that the "Expected CPM" of the EMF and the EMF "Trip I" Setpoint are less than the "Trip II" Setpoint.

Answer A Discussion INCORRECT: The RECOMMENDED RELEASE RATE is also incorrect.

PLAUSIBLE: The "allowable release rate" is determined by the amount of activity present in the tank. The "recommended release rate" is the release rate limit imposed by the procedure (i.e. LWR). The operator will set the release rate at the value of the recommended release rate. This answer is plausible if the applicant confuses the terms and think that "allowable" is the procedural limit instead of the "recommended".

Answer B Discussion INCORRECT: There is also an inadequate number of RC pumps running to dilute all concurrent releases. Under the RC PUMP DATA, the "Total RC Pumps required (all concurrent releases)" will normally be equal to "RC pumps assigned to RELEASE". However it can be higher if more than one liquid release is occurring at one time. Under the conditions associated with this LWR, another liquid release is occurring, and the total RC pumps required is higher.

PLAUSIBLE if the candidate fails to realize another release is occurring and/or believes the only concern is RC pumps associated with this release.

Answer C Discussion CORRECT. See explanation above.

Answer D Discussion INCORRECT: There are two problems with this LWR. Inadequate number of RC pumps running and incorrect Recommended Release Rate.

PLAUSIBLE: The "allowable release rate" is determined by the amount of activity present in the tank. The "recommended release rate" is the release rate limit imposed by the procedure (i.e. LWR). The operator will set the release rate at the value of the recommended release rate. This answer is plausible if the applicant confuses the terms and think that "allowable" is the procedural limit instead of the "recommended".

PLAUSIBLE if the candidate fails to realize another release is occurring and/or believes the only concern is RC pumps associated with this release.

Cognitive Level Comprehension Job Level SRO QuestionType MODIFIED Question Source Bank 898 Basis for meeting the KA This KA deals with Accidental Liquid Radioactive-Waste Release. An Accidental Release could be an uncontrolled or unmonitored release, or one that is not adquately diluted. There are three items the SRO must verify before approving a release: Adequate number of RC pumps for dilution, Recommended Release Rate is less than or equal to the Allowable release rate, and EMF Trip 2 setpoint. A release rate that is too high, or an inadequate number of RC pumps running could result in inadquate dilution of the release. Therefore this KA is matched.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. The SRO must recall from memory the purpose of each section of the LWR, then determine if it meets the requirements.

Basis for SRO only This is SRO level because the SRO is responsible for authorizing the release based on given conditions.

92 General Discussion AP-45 (Plant Fire). Enclosure 13 (AB 733' Battery Room Fire Unit 1 and 2 Actions) directs the operators to close the PZR PORV Block Valves for both units.

AP-45 directs that the action to close the PORV Block Valves is time critical. However, the time critical time is only listed in the AP-45 Background document.

In accordance with AP-45:

"Without operator action what could happen after 10 min is a Pzr PORV Isol could be open and the power supply cable to the valve motor could be burnt through. Per Appendix R assumptions, all three isolations may have lost power. Also, the one assumed smart short could be sending an open signal to one PORV. To prevent this scenario, the PORV block valves are closed within 10 minutes, before these failures could occur. "

In accordance with AP-45, the SSF is the assured Safe Shutdown Train for a fire in the Control Room.

Answer A Discussion CORRECT: See explanation above.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

The first part is correct.

The second part is plausible because 30 minutes is a time-critical time that is used extensively throughout the APs.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

The first part is plausible because Train A or B is the assured Safe Shutdown Train credited for many areas in the Auxiliary Building.

The second part is correct.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

The first part is plausible because Train A or B is the assured Safe Shutdown Train credited for many areas in the Auxiliary Building.

The second part is plausible because 30 minutes is a time-critical time that is used extensively throughout the APs.

Basis for meeting the KA While the step that requires closing the PZR PORV Block valves in AP-45 is identified as a time critical step, the required time to close those valves is not identified in AP-45. The only place that the required time is identified is in the AP-45 Basis Document. Since the applicant must have knowledge of specific basis for the step in the AP to know when they must be closed, the KA is met.

Basis for Hi Cog Basis for SRO only Part 1 of this question meets the following criteria for an SRO only question as described in the Clarification Guidance for SRO-only Questions Rev 1dated 03/11/2010 for screening questions linked to 10CFR55.43(b)(5) (Assessment and selection of procedures):

1) This question can NOT be answered by knowing systems knowledge alone. This is strict procedure knowledge.

This is not covered during systems training or discussed in a systems lesson plan.

2) This question can NOT be answered by knowing immediate operator actions.

There are no immediate actions associated with AP-45.

3) This question can NOT be answered by knowing the entry conditions for AOPs.

FOR REVIEW ONLY - DO NOT DISTRIBUTE 2012 MNS SRO NRC Examination QUESTION 93 C

93 General Discussion From the conditions given, an ORANGE condition exists on the Containment CSFST that requires FR-Z.2 be implemented (i.e. Containment pressure less than 15 PSIG - YES => Containment pressure less than 3 PSIG - YES => Containment Sump Level less than 12.5 FT - NO (Top of the scale is 20 ft) => GO TO FR-Z.2).

There is a YELLOW condition on Core Cooling due to which would require FR-C.3 to be implmented (i.e. CETs < 1200°F - YES => NC Subcooling based on CETs > 0°F - NO => At least one NC Pump ON - NO => CETs Less than 700°F - YES => Reactor Vessel Lower Range Level Greater Than 39% - YES => GO TO FR-C.3)

From the FRZ Lesson Plan (Basis Document):

The maximum level of water in the containment following a major accident generally is based upon the stored water volumes from the FWST, CLAs, ice condenser, and NC system. This water volume approximates the maximum water volume introduced into the containment following a LOCA plus a steamline or feedline break inside containment.

An indicated water level in the containment greater than the maximum expected volume (design basis flood level) is an indication that water volumes other than those represented by the above noted volumes have been introduced into the containment. Also, the high water level provides an indication that potential flooding of critical systems and components needed for plant recovery may occur. Identification and isolation for any broken or leaking water line inside containment is essential to maintaining the water level below the design basis flood level.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because the indications show some loss of core cooling has occurred due to the loss of inventory in the core.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant fails to recall the level at which core uncovery occurs. If that were the case, they would conclude that the core has become uncovered and this would be the correct response.

Answer C Discussion CORRECT: See explanation above.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because the total volume of the NC system and the total volume of the FWST emptying into Containment would cause a substantial rise in Containment sump levels. These are also plausible because they are expected inputs into the Containment sump during an accident. If the applicant fails to recall, from the basis document all of the inputs that contribute to the normal increase in sump level during an accident they could incorrectly conclude that this is the correct response.

Basis for meeting the KA The KA is matched because the applicant must have knowledge of the CSFSTs to prioritize which procedure must be implemented and must have knowledge of the FRZ Basis Document to determine the basis for why the procedure is being implemented.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. The applicant must first recall from memory the Containment and Core Cooling CSFSTs. The applicant must then analyze the conditions given to determine what conditions have been met and what Functional Restoration Procedure must be implemented. The applicant must also recall from the Basis Document the reason why the CSF has been jeopordized making it a priority for implementation.

Basis for SRO only This question meets the following criteria for an SRO only question as described in the Clarification Guidance for SRO-only Questions Rev 1 dated 03/11/2010 for screening questions linked to 10CFR55.43(b)(5) (Assessment and selection of procedures):

95 General Discussion In accordance with Tech Spec 3.4.15 Basis:

"The reactor coolant contains radioactivity that, when released to the containment, can be detected by radiation monitoring instrumentation. U.S.

NRC Regulatory Guide (RG) 1.45, Reactor Coolant Pressure Boundary Leakage Detection Systems, (Ref. 2), describes acceptable methods of implementing the requirements for leakage detection systems. Although RG 1.45 is not a license condition, it is generally accepted for use to support licensing basis. RG 1.45 states that instrument sensitivities of 10-9 µCi/cc radioactivity for air particulate monitoring are practical for leakage detection systems. The containment atmosphere particulate radioactivity monitor at McGuire meets or exceeds this accepted sensitivity.

RG 1.45 also states that detector systems should be able to respond to a one gpm leak, or its equivalent, in one hour or less. The containment atmosphere particulate radioactivity monitor at McGuire has demonstrated capabilities of detecting a 1.0 gpm leak within one hour at the sensitivity recommended in Regulatory Guide 1.45 using the RCS corrosion product activities from the UFSAR."

For MNS, 1(2) EMF-38 are the credited RG 1.45 radiation monitors.

Tech Spec 3.4.15 Basis also states:

"As leakage may go to either or both of the two CFAE sumps, a 1 gpm sump input (cumulative between sumps A and B) is detectable in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> after leakage has reached the sumps (Ref 8)."

Answer A Discussion CORRECT: See explanation above.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because Containment temperature is discussed in Tech Spec 3.4.15 Basis as one of the diverse indications of "rapid and sizeable leakage to the containment".

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because the incore instrument sump level is credited by Tech Spec 3.4.15 as being able to detect a 1 GPM leak within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because 2EMF-39 will most likely alarm if there is significant leakage into containment. Also, the applicant could confuse 2EMF-39 with 2EMF-38 and conclude that BOTH are credited with detecting a 1 GPM leak within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

Basis for meeting the KA The KA is matched because the applicant must have knowledge of the TS Basis to be able to identify which indication would be a diverse indication credited for identifying a small NC system leak into containment.

97 General Discussion In accordance with RP-004 (General Emergency), the emergency exposure limit for this task is 10 REM (protecting valuable equipment).

The operator must transit through a 15R/hr area to get to the 1B ND pump room.

Therefore:

15 R/hr ÷ 60 min/hr = 0.25 R/min So, exposure for the transit:

0.25 R/min x 4 min (2 min each way) = 1 R total (leaving 9 R for work in the room)

Exposure in the room:

30 R/hr ÷ 60 min/hr = 0.5 R/min Allowable Stay Time in room:

9 R ÷ 0.5 R/min = 18 min.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant concludes that the emergency exposure limit is 5 REM which is the limit specified in RP-004 (General Emergency) for all work except that to protect "valuable equipment", "lifesaving", or "protect the public" (which have higher emergency dose limits).

If the applicant concludes that 5 REM is the limit and performs all other calculations correctly this would be the correct answer.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant concludes that the emergency exposure limit is 5 REM which is the limit specified in RP-004 (General Emergency) for all work except that to protect "valuable equipment", "lifesaving", or "protect the public" (which have higher emergency dose limits).

The applicant would also have to calculate the transit time in only one direction to select this as a correct answer. This is plausible as this is a common error for this type of assessment.

Answer C Discussion CORRECT: See explanation above.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible if the applicant calculates the stay time using a transit exposure in only one direction. This is a common error for this type of assessment. If the applicant recalls the correct emergency exposure limit and performs the stay time calculation using transit exposure in only one direction, this would be the response selected.

Basis for meeting the KA The KA is matched because the applicant must have knowledge of radiological safety principles such as calculating stay times to determine the correct response.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. First, it requires the applicant to recall from memory the emergency exposure limit for the task described. The applicant must then perform a calculation to determine the maximum stay time to prevent exceeding that emergency exposure limit.

[10 CFR 55.43(b)(4)].

The question involves "analysis and interpretation of radiation and activity readings" as they relate to "emergency" procedures in that the applicant must recall emergency exposure limits from RP-004 (General Emergency) and apply that knowledge to the conditions given to analyze the proposed task and determine how long the Operator may stay in the 1B ND pump room. Knowledge of emergency exposure limits is SRO-level knowledge.

FOR REVIEW ONLY - DO NOT DISTRIBUTE 2012 MNS SRO NRC Examination QUESTION 98 D

98 General Discussion To maintain station dose ALARA, the worker/team with the lowest dose for the job consistent with meeting all other exposure limits should be selected.

Team A would receive 750 mREM each and a team total of 1500 mREM. However, Worker B would exceed their annual exposure limit.

Team B would receive 1000 mREM each for a team total of 2000 mREM. Consequently, the total exposure for the valve alignment would be the highest of all teams.

Team C would receive 375 mREM each for a team total of 1125 mREM. This is the lowest total exposure of all teams. However, Worker A would exceed their annual exposure limit.

Team D would receive 500 mREM each for a team total of 1500 mREM. This is the second lowest exposure (tied with Team A) for the valve alignment. While Team D has the highest overall exposure of any team (i..e. total annual exposure + team exposure for the valve alignment),

they are the best choice because of low team exposure and the fact that no one will exceed their annual exposure limit.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because the total team exposure for the valve alignment is low (i.e. the second lowest for all teams). The only team with a lower total exposure for the valve alignment (Team C) can NOT be used because Worker A will exceed the NRC annual exposure limit.

Therefore, if the applicant does not realize that Worker B would exceed the NRC annual exposure limit, they would conclude that this would be the best team.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because Team B has the lowest total team exposure prior to the valve alignment. If the applicant does not realize that Team B total team exposure for the valve alignment is the highest of all teams, they could conclude that Team B is the best choice.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

This answer is plausible because Team C would have the lowest total team exposure for the valve alignment. If the applicant does not realize that Worker A would exceed the NRC annual exposure limit, they would conclude that Team C is the best choice.

Answer D Discussion CORRECT: See explanation above.

Cognitive Level Comprehension Job Level SRO QuestionType NEW Question Source Basis for meeting the KA The KA is matched because the applicant must evaluate the radiation hazard to a team of workers performing a valve alignment.

Basis for Hi Cog This is a higher cognitive level question because it requires more than one mental step. It requires the applicant to perform mutilple calculations and compare the results of all those calucalations to each other and to recalled memory to determine the best choice.

Basis for SRO only This question is SRO level knowledge because it can not be answered solely by RO knowledge of radiological safety principles (e.g., RWP requirements, stay-time, DAC-hours, etc.).

It requires the applicant to analyze the makeup of the available teams with regards to the total exposure for the job and the accumulated annual exposure for the teams and make a determination as to which team would be the correct choice to maintain station dose ALARA.

The second part of the answer is correct.

Answer B Discussion CORRECT: See explanation above.

Answer C Discussion INCORRECT: See explanation above.

PLAUSIBLE:

The first part of the answer is plausible because this would be the correct follow-up time if the declared emergency was an Alert or higher.

The second part of the answer is plausible because this is the system that would be used if the Selective Signaling System and Standard Phone Lines were unavailable.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

The first part of the answer is correct.

The second part of the answer is plausible because this is the system that would be used if the Selective Signaling System and Standard Phone Lines were unavailable.

Basis for meeting the KA The KA is matched because the applicant must have knowledge of the systems used to communicate with offsite agencies in the event of an emergency. Also, by demonstrating a knowledge of when follow-up notifications are required, the applicant is demonstrating a knowledge of emergency communication techniques.

FOR REVIEW ONLY - DO NOT DISTRIBUTE 2012 MNS SRO NRC Examination QUESTION 100 C

100 General Discussion In accordance with RP-004 (General Emergency) a Protective Action Recommendation (PAR) for the general public is required as part of the notification of General Emergency.

There is no requirement in RP-003 (Site Area Emergency) to make a Protective Action Recommendation to the general public. However, on-site PARs can be made (e.g. site evacuation) and in some instances are made during a Site Area Emergency. Additionally, a Site Assembly is required as an on-site protective action in the event of a SAE.

In the event a PAR is required all zones with 5 miles of the plant are required to evacuate if wind speeds are less or equal to 5 MPH. If wind speed is greater than 5 MPH, the area within 2 miles of the plant and all zones 5 miles downwind are required to evacuate.

Answer A Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Site Area Emergency is plausible because on-site PARs can be made at this emergency action level. Also, the protective action of performing a Site Assembly is required for a SAE. It is plausible for the applicant to conclude that since protective actions are required on-site that off-site PARs are required as well.

The second part is correct.

Answer B Discussion INCORRECT: See explanation above.

PLAUSIBLE:

Site Area Emergency is plausible because on-site PARs can be made at this emergency action level. Also, the protective action of performing a Site Assembly is required for a SAE. It is plausible for the applicant to conclude that since protective actions are required on-site that off-site PARs are required as well.

The second part is plausible because both initial PARs require some type of action at the five mile radius. In the event a PAR is required all zones with 5 miles of the plant are required to evacuate if wind speeds are less or equal to 5 MPH. If wind speed is greater than 5 MPH, the area within 2 miles of the plant and all zones 5 miles downwind are required to evacuate. If the applicant recalls the 5 mile radius requirement from both initial PAR requirements and does not recall the 2 mile requirement, this answer is plausible.

Answer C Discussion CORRECT: See explanation above.

Answer D Discussion INCORRECT: See explanation above.

PLAUSIBLE:

General Emergency is correct.

The second part is plausible because both initial PARs require some type of action at the five mile radius. In the event a PAR is required all zones with 5 miles of the plant are required to evacuate if wind speeds are less or equal to 5 MPH. If wind speed is greater than 5 MPH, the area within 2 miles of the plant and all zones 5 miles downwind are required to evacuate. If the applicant recalls the 5 mile radius requirement from both initial PAR requirements and does not recall the 2 mile requirement, this answer is plausible.

Basis for meeting the KA The KA is matched because the applicant must have knowledge of when protective action recommendations are required and the minimum distance from the plant which must be evacuated when a PAR is made.

Basis for Hi Cog Basis for SRO only This question meets the following criteria for an SRO only question as described in the Clarification Guidance for SRO-only Questions Rev 1 dated 03/11/2010 for screening questions linked to 10CFR55.43(b)(5) (Assessment and selection of procedures):
