K/A MATCH ANALYSIS The question sets up a plausible scenario where rods withdrawal due to some internal failure inserts some amount of positive reactivity. Once operator action is taken rod motion stops and the candidate must address how the core will respond to the inserted reactivity and the impact of the stuck rod, ther efore the two element s are in place that the KA requires. The OPERABILITY determination for the affect rod is SRO required knowledge.EXPLANATION OF REQUIRED KNOWLEDGE As control rods are withdrawn, an increase in fission rate will occur. The resulting fuel centerline temperature increase from the positive reac tivity addition will be offset by FTC and MTC feedback. As a result, reactor power will tr end down toward the orginial power level with and increas e RCS average temper ature. Since RCS temperature is higher than the orginial temperature, SG pr essure will also be slig htly elevated. The higher SG pressure will result in slight increase in steam flow as compared to the original conditions. Ther efore, reactor power will be slightly higher than thepre-transient value.

K/A MATCH ANALYSIS The question sets up a plausible scenario where rods withdrawal due to some internal failure inserts some amount of positive reactivity. Once operator action is taken rod motion stops and the candidate must address how the core will respond to the inserted reactivity and the impact of the stuck rod, therefore the two elements are in place that the KA requires. The OPERABILITY determination for the affect rod is SRO required knowledge.
Part 2 is correct requiring the candidate to recall Tech Spec 3.1.4 'Rod Group Alignment Limits' bases which tiesOPERABILITY to trippability of the rods. The rod OPERABILITY(i.e., trippability) requirement is satisfied provided that the rod will fully insert in the require d rod drop time assumed in the safety analyses. Rod control malf unctions that result in the inability to move a rod (e.g., rod lift coil failures), but that do not impact trippability, do not result in rod inoperability. However, where rod(s) are not moving, t he rod(s) must be considereduntrippable unless there is verification that a rod control system failure is preventing rod motion. If the rod control system is
EXPLANATION OF REQUIRED KNOWLEDGE As control rods are withdrawn, an increase in fission rate will occur. The resulting fuel centerline temperature increase from the positive reactivity addition will be offset by FTC and MTC feedback. As a result, reactor power will trend down toward the orginial power level with and increase RCS average temperature. Since RCS temperature is higher than the orginial temperature, SG pressure will also be slightly elevated. The higher SG pressure will result in slight increase in steam flow as compared to the original conditions. Therefore, reactor power will be slightly higher than the pre-transient value. This is a fundamental reactor theory concept.
Per TS 3.1.4 Bases, the OPERABILITY requirements (i.e. trippability) are seperate from the alignment requirements. Even if a rod is >12 steps misaligned, it is still OPERABLE.
Where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. Since rod motion was demanded and did not occur and there is nothing given in the stem to explain the loss of motion, the candidate must declare rod H8 inoperable.
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is 'plausible' however incorrect in that the candidate may determine that reactor power will rise to a new higher equilibrium value and stabilize. Thus, the candidate failed to take into count the reactivity feedback mechanisms of MTC and FTC on core behavior. In addition, the answer would be correct under some plant condition like during startup steam dumps in steam pressure mode.
Part 2 is 'plausible' but is also incorrect in that the candidate must consider the affected rod inoperable until proven trippable as stated in Tech Spec 3.1.4 Rod Group Alignment Limits bases; However, where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. If the rod control system is demanding motion properly and no motion occurs, the rod is considered untrippable (i.e., inoperable). This operability call is contrary to the standard philosophy that a component is considered OPERABLE until determined otherwise.
B. Incorrect. Plausible. Part 1 is 'plausible' however incorrect. See Part 1 of choice A above.

demanding motion properly and no motion occurs, the rod is
Part 2 is correct requiring the candidate to recall Tech Spec 3.1.4 Rod Group Alignment Limits bases which ties OPERABILITY to trippability of the rods. The rod OPERABILITY (i.e., trippability) requirement is satisfied provided that the rod will fully insert in the required rod drop time assumed in the safety analyses. Rod control malfunctions that result in the inability to move a rod (e.g., rod lift coil failures), but that do not impact trippability, do not result in rod inoperability. However, where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. If the rod control system is demanding motion properly and no motion occurs, the rod is considered untrippable (i.e., inoperable).
C. Incorrect. Plausible. Part 1 is correct which is addressing core response and correctly predicts that the positive reactivity will be offset by FTC and MTC feedback. Over time the reactor power will lower to near original values, only slightly higher due to TAVG being raised which results in an increase in Steam Generator pressure. This would result in a small increase in steam flow.
Part 2 is 'plausible' but is also incorrect. See Part 2 of choice A above.
D. Correct.                  Part 1 is correct. See Part 1 of choice C above.
Part 2 is correct. See Part 2 of choice B above.

Rod Group Alignment Limits B 3.1.4   (continued)Vogtle Units 1 and 2 B 3.1.4-5 Rev. 1-8/03 BASES (continued) LCO The limits on shutdown or control rod alignments ensure that the assumptions in the safety analysis will remain valid. The requirements on OPERABILITY ensure that upon reactor trip, the assumed reactivity will be available and will be inserted. The OPERABILITY requirements (i.e., trippability) are separate from the alignment requirements which ensure that the RCCAs and banks maintain the correct power distribution and rod alignment.
The rod OPERABILITY (i.e., trippability) requirement is satisfied provided that the rod will fully insert in the required rod drop time assumed in the safety analyses. Rod control malfunctions that result in the inability to move a rod (e.g., rod lift coil failures), but that do not impact trippability, do not result in rod inoperability. However, where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion.

If the rod control system is demanding motion properly and no motion occurs, the rod is considered untrippable (i.e.,
inoperable). The requirement to maintain the rod alignment to within plus or minus 12 steps of their group step counter demand position is conservative. The safety analysis assumes a total misalignment from fully withdrawn to fully inserted. When required, movable incore detectors may be used to determine rod position and verify the rod alignment requirement of this LCO is met. Failure to meet the requirements of this LCO may produce unacceptable power peaking factors and LHRs, or unacceptable SDMs, all of which may constitute initial conditions inconsistent with the safety analysis. APPLICABILITY The requirements on RCCA OPERABILITY and alignment are applicable in MODES 1 and 2 because these are the only MODES in which a self-sustaining chain reaction (K eff 1) occurs, and the OPERABILITY (i.e., trippability) and alignment of rods have the potential to affect the safety of the plant. In MODES 3, 4, 5, and 6, the alignment limits do not apply because the control rods are fully inserted and the reactor is shut down, with no self-sustaining chain reaction. In the shutdown MODES, the OPERABILITY of the shutdown and control rods has the potential to affect the required SDM, but this effect can be compensated for by an increase in the boron concentration of the RCS. See LCO 3.1.1, "SHUTDOWN MARGIN (SDM)," for SDM in MODES 3, 4, and 5 and LCO 3.9.1, "Boron Concentration," for boron concentration requirements during refueling.

EXPLANATION OF REQUIRED KNOWLEDGE The IPC calculates the rod insertion limit using real time data. When the alarm is generated the candidate would be expected to verify the validity of the alarm. This evaluation would be accomplished using IPC and Tech Spec data with backup from QMCB indications. In addition, the Shift Supervisor is required the make a decision to withdrawal control rods based on NMP-OS-001 Reactivity Management Program guidance.

The control room team shall not immediately dilute or withdraw control rods in an attempt to restore RCS Tavg/Tref deviations caused by a secondary plant transient.
/Tref deviations caused by a secondary plant transient.Attempts to immediately restore RCS Tavg/T ref deviations caused by a secondary plant transient can be aggravated by withdra wing control rods or reducing boron concentration with reactor power rising.
Attempts to immediately restore RCS Tavg/Tref deviations caused by a secondary plant transient can be aggravated by withdrawing control rods or reducing boron concentration with reactor power rising. Per NMP-OS-001, once turbine load has been stabilized and RCS Tavg has been restored to within 3°F of Tref, positive reactivity can be added by withdrawing control rods.
Per NMP-OS-001, once tu rbine load has been stabilized and RCS Tavg has been restored to wit hin 3°F of Tref, positive reactivity can be added by withdra wing control rods.ANSWER / DISTRACTOR ANALYSISA. Correct. The first part is correct. Per the IPC printout, RCS DeltaT Power is approximately 83% and CBD position is 116 steps.
ANSWER / DISTRACTOR ANALYSIS A. Correct.                   The first part is correct. Per the IPC printout, RCS DeltaT Power is approximately 83% and CBD position is 116 steps.
The IPC uses Auctioneered Hi gh DeltaT Power for the RIL calculation. Per the COLR, th e RIL for 83% po wer is 122 steps on CBD. Therefore, ALB10-D04 is a valid alarm.
The IPC uses Auctioneered High DeltaT Power for the RIL calculation. Per the COLR, the RIL for 83% power is 122 steps on CBD. Therefore, ALB10-D04 is a valid alarm.
The second part is correct.
The second part is correct. Per NMP-OS-001 step 6.1.2.4, once turbine load has been stabilized and RCS Tavg has been restored to within 3° of Tref, positive reactivity can be added by withdrawing control rods. Both of these conditions have been met. Therefore, control rod withdrawal is not restricted.
Per NMP-OS-001 step 6.1.2.4, once turbine load has been stab ilized and RCS Tavg has been restored to within 3° of Tref, po sitive reactivity can be added by withdrawing control rods. Both of these conditions have been met. Therefore, control r od withdrawal is not restricted.B. Incorrect. Plausible. The first part is correct. See the first part of Choice A above.
B. Incorrect. Plausible. The first part is correct. See the first part of Choice A above.
The second part is incorrect.
The second part is incorrect. Per NMP-OS-001 step 6.1.2.4, rod withdrawals are allowed if Tavg/Tref devation is within 3°F.
Per NMP-OS-001 step 6.1.2.4, rod withdrawals are allowed if Tavg/Tref devation is within 3°F.
However, NMP-OS-001 step 6.1.2.4 states it is non-conservative to withdraw control rods in response to a transient and anomalies are to be mitigated utilizing the secondary plant. It is reasonable for a candidate not familiar with the specific guidance of NMP-OS-001 to believe that the Tavg/Tref of 2°F is still considered a "transient" and not allow the use of control rods. Therefore, this distractor is plausible.
However, NMP-OS-001 st ep 6.1.2.4 st ates it is non-conservative to wi thdraw control rods in response to a transient and anomalies are to be mitigated utilizing the
 
secondary plant. It is reaso nable for a candidat e not familiar with the specific guidance of NM P-OS-001 to believe that the Tavg/Tref of 2°F is still consi dered a "transient" and not allow the use of control rods. Therefor e, this distractor is plausible.
C. Incorrect. Plausible. The first part is incorrect. Per the IPC printout, RCS DeltaT Power is approximately 83% and CBD position is 116 steps.
C. Incorrect. Plausible. The first part is incorrect. Per the IPC printout, RCS DeltaT Power is approximately 83% and CBD position is 116 steps.
Per the COLR, the RIL for 83% power is 122 steps on CBD.
Per the COLR, the RIL for 83% power is 122 steps on CBD.
Therefore, ALB10-D04 is a valid alarm. However, if the candidate does not understand ho w RIL is calculated and usesNIS Power instead of DeltaT Po wer, an RIL of 105 steps would be determined and the candidate w ould conclude the alarm wasThursday, February 20, 2014 8:45:05 AM 2

Adding positive reactivity is never an appropriate way to address unstable plant conditions. It is non-conservative to withdraw control rods in response to primary plant anomalies caused by unplanned secondary plant transients. For the PWRs, once turbine load has been stabilized and RCS Tavg has been restored to within 3 degrees of Tref, positive reactivity can be added by withdrawing control rods.
Whenever the status of reactor criticality becomes unknown, the reactor is shutdown.
Under normal conditions, positive reactivity changes will not be performed by more than one means at a time.
During approach to criticality, two positive reactivity additions will not be performed simultaneously.
The operator at the controls shall suspend turnover if a reactivity manipulation is required during turnover.

EXPLANATION OF REQUIRED KNOWLEDGE Per ARP 17008-1 window A05, either low or high seal flow can actuate the alarm. High seal flow is an indication of Seal #1 failure, and low seal flow is an indication of Seal #2 failure. The candidate is given a seal flow of 6.0 gpm to allow differentiation between these two. Window A04 lists a probable cause of Seal #2 failure only. Knowledge of RCP seal package construction is required to understand why this annunciator would be consistent with a Seal #1 failure. As Seal #1 fails, the seal surfaces open and backpressure lowers within the package. Flow down the shaft lowers and increases both to the leak-off path and to Seal #2 .

Per 13003-1, Seal #1 leak-off >5.5 gpm requires stopping the RCP immediately per step 4.2.1.4. With reactor power greater than 15% RTP, the operator is directed to trip the reactor and initiate 19000-C. When the IOA's are complete, the operator is direct to perform steps 4.2.1.4.d thru h to stop the RCP, close the associated spray valve, and isolate seal #1 leak-off.

However, if a candidate has diagnosed a seal #2 failure, 13003-C still supports an immediate stop of the RCP given other conditions. Since the question does not give an option to leave the RCP running, the candidate must assume a valid reason to stop the RCP has been met. As such, if the candidate then does not realize RTP is >15%, then step 4.2.1.4 would direct initiation of AOP 18005-C.

Objective 4 Demonstrate using the seal package model.
The seal package consist of three seals
: 1)  Number 1 seal (film riding) a) The primary seal b) Seal is accomplished with a hydrostatic film between the shaft runner and seal ring.
c) No mechanical contact between seal ring and shaft runner (must keep P >200 psid)
: 2) Number 2 seal (face rubbing) a) Provides back up for #1 seal b) Consist of carbon graphite (face rubbing seal) c) Graphite makes contact with runner which rotates with shaft d) If #1 seal fails , #2 seal converts to a film riding seal if #1 seal leak off valve is closed and seal is exposed to full RCS pressure. #2 seal designed to allow plant shutdown and should last approximately 24 hours.
e) Placing #2 seal in service with the RCP shaft still rotating will tend to score the shaft at the #2 seal area. This can require extensive repairs before placing the RCP back in service. Vogtle chooses to remove RCP from service and allow its shaft to come to a standstill before closing the #1 seal leak off valve to avoid this problem.
: 3) Number 3 seal (face rubbing) a) Prevents the leakage of liquid and gases from the RCS into containment.
b) Consist of carbon graphite seal which makes contact with runner (face rubbing) c) The runner is around the shaft and rotates with it.
d) The seal is actually two graphite sealing surfaces called dams.

Based on the information provided the SRO candidate is required to assess the type of leakage indicated and determine if any emergency action level thresholds were exceeded.

leakage reflects the first part of the KA requirement for a vapor space accident, the second action to quantify the leakage amount and determine any Emergency Plan requirements meets the second part of the KA and brings the question to the SRO knowledge level.
    - CVCS char ging flow is 110 gpm.
EXPLANATION OF REQUIRED KNOWLEDGE The given plant conditions are indicitive of a Pressuirzer Code Safety valve relieving into the PRT. Per TS 3.4.13 Bases, identified leak is defined as being from a specifically known and located source, ie it must be collected and quantifiable, and not pressure boundary. Based on the given conditions, the leakrate is approximately 98 gpm, [charging-(letdown + seal leakoff)]. Total seal leakoff is normally about 12 gpm.
    -  All RCP seal inje ction and #1 seal return flows are within normal operating range.
Since the leakage is across a vavle seat, it is not pressure boundary. Therefore, the leakage described fully meets the definition of IDENTIFIED.
    -  CVCS letdown is isolated.
Per NMP-EP-110-GL03 Figure 1, a potential loss of the RCS barrier exists if RCS leak rate is non-isolatabe and >120 gpm. Since leakrate is calculated to be 98 gpm, this threshold has not been exceeded. Per NMP-EP-110-GL02 Figure 2, NOUE threshold SU5 is exceeded if identified leakage is > than 25 gpm. Therefore, this threshold has been exceeded.
ANSWER / DISTRACTOR ANALYSIS A. Correct.                  Part 1 is correct it required the candidate to determine the type of RCS leakage based on information provided and knowledge of the Tech Spec definition of the various leakage categories.
From the information the candidate should determine this is identified leakage. LEAKAGE, such as that from pump seals or valve packing (except reactor coolant pump (RCP) seal water injection or leakoff), that is captured and conducted to collection systems or a sump or collecting tank.
Part 2 required the candidate to take the information gathered in Part 1 and apply it to the various Emergency Action Level classification thresholds. From that a leak rate of 98 gpm is determined and limits for NOUE recognized as exceeded.
B. Incorrect. Plausible. Part 1 is correct. See Part 1 of choice A above.
Part 2 is incorrect but plausible because the candidate may determine that 110 gpm charging added to 32 gpm seal injection (which is alreay included in the charging flow indicator reading) going into RCS is 142 GPM leak. This minus the RCP seal return flow of 3.2 each gpm would be above the ALERT threshold of 120 gpm for the potential loss of the RCS barrier. (Reference P&IDs 1X4DB114 and 1X4DB116-1)
C. Incorrect. Plausible. Part 1 is incorrect but 'plausible' in that the candidate must first identify the type of RCS leakage. As the PRT continues to recieve effluent from the Przr Code Safety, it will eventually Friday, February 21, 2014 10:13:47 AM                                                                  2

APPLICABLE  Except for primary to secondary LEAKAGE, the safety analyses SAFETY ANALYSES  do not address operational LEAKAGE. However, other operational LEAKAGE is related to the safety analyses for LOCA; the amount of leakage can affect the probability of such an event. The safety analyses for an event resulting in steam discharge to the atmosphere assumes that primary to secondary LEAKAGE from all steam generators (SGs) is one gallon per minute or increases to one gallon per minute as a result of accident induced conditions. The LCO requirement to limit primary to secondary LEAKAGE through any one SG to less than or equal to 150 gallons per day is significantly less than the conditions assumed in the safety analysis.

The RCS operational LEAKAGE satisfies Criterion 2 of 10 CFR 50.36 (c)(2)(ii).
LCO                 RCS operational LEAKAGE shall be limited to:
: a. Pressure Boundary LEAKAGE No pressure boundary LEAKAGE is allowed, being indicative of an off-normal condition. LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE. Violation of this LCO could result in continued degradation of the RCPB. LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.

LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE. Violation of this LCO could result in continued degradation of the RCPB. LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.
: b. Unidentified LEAKAGE One gallon per minute (gpm) of unidentified LEAKAGE is allowed as a reasonable minimum detectable amount that the containment air monitoring and containment sump level monitoring equipment can detect within a reasonable time period. Violation of this LCO could result in continued degradation of the RCPB, if the LEAKAGE is from the pressure boundary.
: b. Unidentified LEAKAGE One gallon per minute (gpm) of unidentified LEAKAGE is allowed as a reasonable minimum detectable amount that the containment air monitoring and containment sump level monitoring equipment can detect within a reasonable time period. Violation of this LCO could result in continued degradation of the RCPB, if the LEAKAGE is from the pressure boundary.
: c. Identified LEAKAGE Up to 10 gpm of identified LEAKAGE is considered allowable because LEAKAGE is from known sources that do not interfere with detection of unidentified LEAKAGE and is well within the capability of the RCS Makeup System. Identified LEAKAGE includes LEAKAGE to the containment from specifically known and located sources, but does not include pressure boundary

Primary to Secondary LEAKAGE through Any One SG The limit of 150 gallons per day per SG is based on the operational LEAKAGE performance criterion in NEI 97-06, Steam Generator Program Guidelines (Ref. 4). The Steam Generator Program operational LEAKAGE performance criterion in NEI 97-06 states, "The RCS operational primary to secondary leakage through any one SG shall be limited to 150 gallons per day."  The limit is based on operating experience with SG tube degradation mechanisms that result in tube leakage. The operational leakage rate criterion in conjunction with the implementation of the Steam Generator Program is an effective measure for minimizing the frequency of steam generator tube ruptures.
APPLICABILITY  In MODES 1, 2, 3, and 4, the potential for RCPB LEAKAGE is greatest when the RCS is pressurized.

Lesser values must generally be determined through time-consuming surveillance test s (e.g., mass balances). The Threshold Value for identified leakage is set at a higher value due to the lesser significance of identified leakage in comparison to unidentified or pressure boundary leakage.

<120F. If the annunciator is in alarm and the IPC is unavail able, then local temperature readings are required.
Per ARP 17001-1 for ALB01-E06, if any of the three contai nment temperature indicators rise above 120F, the operator is instructed to start an additional pair of Containment Coolers. Contai nment Coolers must be start ed in specific pairs (1&2, 3&4, 5&6, and 7&8) due to the backdrafter dampe r for the indivi dual fans being de-energized open on a commo n plentum (reference P&ID 1X4DB212 and SOP 13120-1 section 4.1). Starting the fans one at a time will re sult in the non-running fan of the pair to spinning backwards. When the second fan is subsequently started, the supply breaker will trip ope n from high in-rush current produced by the increasedelectrical slip angle.
Since fan #1 tripped, fan #2 s hould be stopped prior to star ting an additional pair. Fan#2 is mostly recirculating short-cycled flow in the current configuration and is producing little cooling to containment. Simply st arting a second fan on another pair would only create the same condition on a second pair and would also do little to lower containment temperature.ANSWER / DISTRACTOR ANALYSISA. Incorrect.

The question sets up plausible scenario where the candidate must first determine which instruments are required to be referenced when complying with the Containment temperature monitoring verification surveillance of Technical Specifications. A decision is required based on the operating limit in comparison with an IPC screen shot. The second part matches the KA for the Shift Supervisor to evaluate Containment Cooling requirements used to control within environmental limits and the first part makes this SRO required knowledge when the surveillance requirement is tested.
EXPLANATION OF REQUIRED KNOWLEDGE Per TS SR 3.6.5.1, containment average temperature is required to be verified <120F on a periodic bases. The IPC screen for Control Room TS Rounds lists values for CMNT Levels 2, C, & B and an average temperature. Individual readings above 120F are acceptable as long as the average temperature is <120F.
Per OSP 14000-1, page 15, if the IPC points for containment temperature are not available, annunciator ALB01-E06 can be verified extinquished as an alternate. This annunciator utilzes temperature elements from all three levels and has a setpoint of
        <120F. If the annunciator is in alarm and the IPC is unavailable, then local temperature readings are required.
Per ARP 17001-1 for ALB01-E06, if any of the three containment temperature indicators rise above 120F, the operator is instructed to start an additional pair of Containment Coolers. Containment Coolers must be started in specific pairs (1&2, 3&4, 5&6, and 7&8) due to the backdrafter damper for the individual fans being de-energized open on a common plentum (reference P&ID 1X4DB212 and SOP 13120-1 section 4.1). Starting the fans one at a time will result in the non-running fan of the pair to spinning backwards. When the second fan is subsequently started, the supply breaker will trip open from high in-rush current produced by the increased electrical slip angle.
Since fan #1 tripped, fan #2 should be stopped prior to starting an additional pair. Fan
        #2 is mostly recirculating short-cycled flow in the current configuration and is producing little cooling to containment. Simply starting a second fan on another pair would only create the same condition on a second pair and would also do little to lower containment temperature.
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is correct and sets up a circumstance were the candidate must determine which instrumentation in particular is required to be monitored the ensure compliance with SR 3.6.5.1 for Containment temperature. The SR requires the average temperature of three levels in Containment be noted to ensure Containment temperature remains within the accident analyses.

Verifying that containment average air temperature is within the LCO limit ensures that containment operation remains within the limit assumed for the containment analyses. In order to determine the containment average air temperature, an arithmetic average is calculated using measurements taken at locations within the containment selected to provide a representative sample of the overall containment atmosphere. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

EXPLANATION OF REQUIRED KNOWLEDGE Based on the conditions in the stem, 2 EPIPs classification thresholds have been exceed. First, an LOSP has existed with only the 'B' DG energizing 1BA03. As such NOUE CU3 has been exceeded. Additonally, due to both RHR pumps not running, RCS temperature has risen above 200F while in Mode 4. Containment integrity is not established. Since all pressurizer safeties are removed, RCS integrity is also not established. As shuch, ALERT CA4 has also been exceeded. Therefore, the Emergency Director is required to declare an ALERT emergency on or before 11:15 per NMP-EP-110.

Per NMP-EP-111 steps 5.1.1 ad 5.1.3, state and local agencies must be notified within 15 minutes of the declaration, which would be 11:30. Additionally, the NRC shall be notified immediately follwoing the state and local agencies and within an hour of the declaration.
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is incorrect but plausible because the candidate may determine the loss of power event is driving the initial classification not recognizing the loss of RHR Cooling and CU3 would be the correct.
Part 2 is incorrect but plausible because the candidate may determine that the NRC must be notified in this condition within 15 minutes. Per NMP-EP-111, Notification of the NRC shall be completed immediately following notifications to the state and local agencies and within an hour of the declaration of an emergency. Therefore, the NRC is not REQUIRED to be notified by 11:30, but instead is allowed additonal time if needed up to an hour, but is to be done as soon as possible following the state and locals.
B. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice A above.
Part 2 is correct in that within 15 minutes of the classification of the NOUE the state and local authorities must be notified per NMP-EP-111, "Emergency Notifications". Notifications of applicable State and Local Agencies shall be accomplished as soon as practicable and within 15 minutes of the declaration of an emergency, an upgrade to a higher emergency classification level, or the approval of protective actions recommendations.
C. Incorrect. Plausible. Part 1 is correct and has the candidate evaluate plant conditions and determine the event meets the ALERT threshold for CA4 due to being in Mode 5 with RCS temperature >200F without containment and RCS integrity established.

5.0 PROCEDURE 5.1 Precautions and Limitations 5.1.1 Notifications of applicable State and Local Agencies shall be accomplished as soon as practicable and within 15 minutes of the declaration of an emergency, an upgrade to a higher emergency classification level, or the approval of protective actions recommendations. 5.1.2 Electronic notification using the electronic Emergency Notification Form (ENF) in WebEOC is the preferred method of notification of State and Local Agencies. Should WebEOC be unavailable the back-up notification method is completion of a hard copy ENF and reading the form to the applicable State and Local Agencies via the ENN. Whether using the electronic or back-up ENF the emergency notification to an agency is considered complete when the agency verbally confirms receipt of the message via the ENN. To expedite availability of WebEOC in an emergency, the crew members responsible for completing the ENF and making electronic notifications should login to WebEOC as soon as possible and remain logged-in. 5.1.3 Notification of the NRC shall be completed immediately following notifications to the state and county agencies and within an hour of the declaration of an emergency. Follow-up notifications of the NRC shall be made promptly after any further degradation in the plant conditions, any change from one emergency class to another, or for the termination of an emergency. NRC notifications are typi cally performed utilizing the Federal Telephone System (FTS). The Emergency Notification System (ENS) line is normally utilized. An open line is maintained for the duration of the event at the request of the NRC communicator receiving the initial notification. 5.1.4 For security based emergencies, notifications to the NRC should be performed within 15 minutes of discovery of an imminent threat or attack against the plant to ensure proper mobilization of federal resources.

5.1.5 If the plant condition degrades and a higher emergency classification is declared before the notifications are confirmed for the lesser emergency declaration, then a notification reflecting the higher emergency classification should be made. This notification should be made within 15 minutes of the lesser emergency declaration. This should be performed IF the notification can be made within 15 minutes of the lesser (first) classification.

before that component may be damaged.K/A MATCH ANALYSIS To answer this question, the applicant must kn ow that loss of ACCW will lead to entry into 19000-C, requiring a m anual trip (even though it d oes not approach or exceed any automatic setpoints), and whic h procedure provides the action. Since the Shift Supervisor is required to recall the specif ic strategy from t he 18022-C procedure, the choices involve SRO only kno wledge of the procedure flow path of the AOP (past the entry conditions and there are no immediate actions in 180 22-C), and knowledge of the need to enter 19000-C. In addition, the question requires the c andidate to recall not only how long the RCPs can operate without ACCW coolin g but to evaluate other parameters that may require i mmediate stopping of the pumps.EXPLANATION OF REQUIRED KNOWLEDGE At 1005, annunciators ALB04-A03 and A04 indicate a co mplete loss of ACCW flow toRCP #1 only. AOP 18022-C is entered. Step 6 checks to see if the RCP should be stopped. At 1016, RCP #1 wo uld have sustained a total loss of ACCW for >10 minutes and must be stopped. The stem al so states that seal water inlet temperature is rising at a rate of 1F/min. At 1018, the RCP must be stopped due to seal water inlet temperature. Additionally, motor stator winding temperature is al so rising at a rate f 1F/min. At 1012, 311F would have been exceeded and the RCP must be stopped.
K/A MATCH ANALYSIS To answer this question, the applicant must know that loss of ACCW will lead to entry into 19000-C, requiring a manual trip (even though it does not approach or exceed any automatic setpoints), and which procedure provides the action. Since the Shift Supervisor is required to recall the specific strategy from the 18022-C procedure, the choices involve SRO only knowledge of the procedure flow path of the AOP (past the entry conditions and there are no immediate actions in 18022-C), and knowledge of the need to enter 19000-C. In addition, the question requires the candidate to recall not only how long the RCPs can operate without ACCW cooling but to evaluate other parameters that may require immediate stopping of the pumps.
Therefore, the most limi ting operationg c ondition would be the stator winding temperature and the the RCP must be stopped no later than 1012. The RCP operationg parameters in 18022-C are the same as those listed in SOP 13003-1 Limitation 2.2.10.
EXPLANATION OF REQUIRED KNOWLEDGE At 1005, annunciators ALB04-A03 and A04 indicate a complete loss of ACCW flow to RCP #1 only. AOP 18022-C is entered. Step 6 checks to see if the RCP should be stopped. At 1016, RCP #1 would have sustained a total loss of ACCW for >10 minutes and must be stopped. The stem also states that seal water inlet temperature is rising at a rate of 1F/min. At 1018, the RCP must be stopped due to seal water inlet temperature. Additionally, motor stator winding temperature is also rising at a rate f 1F/min. At 1012, 311F would have been exceeded and the RCP must be stopped.
Therefore, the most limiting operationg condition would be the stator winding temperature and the the RCP must be stopped no later than 1012. The RCP operationg parameters in 18022-C are the same as those listed in SOP 13003-1 Limitation 2.2.10.
Since the reactor is greater than 15% RTP, the reactor must be tripped prior to tripping the RCP. Tripping the reactor is a direct entry condition into EOP 19000-C. On step 11 of 19000-C, a check of ACCW status is made and the RNO directs stopping the RCP.

However, 18022 step 6 is specifically design to trip the reactor and stop the RCP prior to performing EOP 19000-C. Th is is done to ensure the RCP is not damaged in the time required to perform the in itial steps of 19000-C before direction to stop the RCP is encountered.ANSWER / DISTRACTOR ANALYSISA. Correct. Part 1 is correct. Base d of Westinghouse ve ndor requirements the RCPs must be stopped under normal conditions when ACCW cooling is lost to the motors to prevent potential damage. This is supported by SOP 13003-1, which establishes the ACCW operating ti me limit of 10 minutes and other trip parameters. In the case pres ented to the candidate the most limiting parameter is the stator limit of 311F which will require the pump to be stopped within 5 minutes of 10:07 (i.e. 10:12).

Part 2 is correct because 18022-C directs manual reactor trip, verify trip, the stop RCPs th en perform 19000-C, therefore the correct direction to stop the RCP is 18022-C as opposed to 19000-C.Friday, February 21, 2014 1:21:51 PM 2
ANSWER / DISTRACTOR ANALYSIS A. Correct.                 Part 1 is correct. Based of Westinghouse vendor requirements the RCPs must be stopped under normal conditions when ACCW cooling is lost to the motors to prevent potential damage. This is supported by SOP 13003-1, which establishes the ACCW operating time limit of 10 minutes and other trip parameters. In the case presented to the candidate the most limiting parameter is the stator limit of 311F which will require the pump to be stopped within 5 minutes of 10:07 (i.e. 10:12).

Part 2 is incorrect but plausible because the candidate may determine that the direction that is provided in 19000-C step 11 would be used to stop the RCPs as opposed to 18022-C step 1.
The 10 minute time allowance could lead the candidate to determine there is no real pressure to speed up the action to stop the RCPs, prior to the initial steps in 19000-C.
C. Incorrect. Plausible. Part 1 is incorrect however is plausible since the candidate may determine that none of the operating limits provided in the stem is above limits or will reach their limit within 10 minutes, therefore the 10 minutes becomes the most limiting factor.

SRO JUSTIFICATION (5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.
        -Can the question be answered solely by knowing systems knowledge, i.e.,
how the system works, flowpath, logic, component location? No, the system parameter needed to determine if the RCP should be stopped is system level knowledge. However, the direction to stop the RCP requires specific knowledge and priortization of steps in both the AOP and EOP.
        -Can the question be answered solely by knowing immediate operator actions?
No, there are no IOAs associated with the actions addressed in this question.
        -Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, stopping an RCP has nothing to do with the entry conditions for either AOP 18022-C or EOP 19000-C. 19000-C does have entry conditions associated with trip of the reactor, which would stem from stopping an RCP at 100% RTP. However, this would lead a candidate down the incorrect path.
        -Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, specific knowledge of individual procedure steps is required.
        -Does the question require one or more of the following?
* Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed

ANSWER / DISTRACTOR ANALYSIS A. Correct.                Part 1 is correct. Per 10020-C 'EOP and AOP Rules of Usage', Other procedures such as AOPs or ARPs may be performed in parallel with EOPs as long as their actions do not conflict with the EOP steps. EOP actions take priority.
5.9, other procedures such as AOPs and ARPs   may be performed in parallel with EOPs as long as their actions do not conflict with the EOP steps. EOP actions take priority.
Additionally, performance of 18001-C to restore pressurizer heaters is prudent and necessary.
In both steps 21 and 26 of EOP 19011-C, pressurizer heaters are required to be energized to saturate the pressurizer. With pressurizer level at 92% and rising, th is becomes a crucial action, however the step cannot be accomplished due to heaters being tripped o ff as a result of LT-459 failing low. The use of 18001-C to select away from the failed channel and restore pressurizer heaters is a prudent and necessary action.With pressurizer level at 92% and rising, a yellow path on the CSFST for INVENTORY should exist. Per 1 9200-C step 1 RNO, if a yellow path exist, then initiate FRP based on plant conditions with Shift Supervisor approval.
Part 2 is correct. 19200-C 'Critical Safety Function Status Trees', states IF a Yellow condition exists, THEN initiate FRP after evaluating plant conditions with Shift Supervisor's approval. 19011-C "SI Termination' states IF solid plant conditions are present, THEN refer to 19261 C, FR I.1 Response to High Pressurizer Level. Solid plant conditions are not present. Entry into 19261-C would actually impede the success path in 19011-C.
Per step 11 RNO, transition to FRP 19261-C should only be made if solid plant condtions exist, which are not currently present. Therefore, 19261-C is not required to be entered and should not be entered at this time. Instead, the prio rity should be placed on restor ing pressurizer heaters andcontinuing efforts to lower pressurize r level via charging/letdown mismatch.ANSWER / DISTRACTOR ANALYSISA. Correct. Part 1 is correct.

Part 2 is incorrect but 'plausible' because the candidates know that EOP actions always take priority. The candidate may not realize 19261-C does not contain any steps that would be different from those already in progress in 19011-C and believe transition to 19261-C is necessary to prevent going solid in the pressurizer.

Additionally, the candidate is required to determine the SR NI indication following a loss of the high voltage power supply. In this situation, the NI detector would be down powered and the indication would drop to bottom of scale.
Additionally, the candidate is required to determine the SR NI indication following a loss of the high voltage power supply. In this situation, the NI det ector would be down powered and the indication would drop to bottom of scale.ANSWER / DISTRACTOR ANALYSISA. Incorrect. Plausible. The first part is correct. When any of the safety-related busses supplying power to one of the detectors (NI-0031 or NI-0032) associated with the source r ange neutron flux monitors are taken out of service, the co rresponding source range neutron flux monitor may be considered OPERABLE when its detector is powered from a temporary nons afety-related power source, provided the detector for the oppo site source range neutron flux monitor is powered from its normal source.
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is correct. When any of the safety-related busses supplying power to one of the detectors (NI-0031 or NI-0032) associated with the source range neutron flux monitors are taken out of service, the corresponding source range neutron flux monitor may be considered OPERABLE when its detector is powered from a temporary nonsafety-related power source, provided the detector for the opposite source range neutron flux monitor is powered from its normal source.
The second part is incorrect.
The second part is incorrect. Loss of the high voltage power supply will constitute a complete loss of power to the SR NI detectors, resulting in indication failing to bottom of scale.
Loss of the hi gh voltage power supply will constitute a complete loss of power to the SR NI detectors, resulting in indication failing to bottom of scale.
However, the NI's have 3 different power supplies that support various functions. If a loss of control power only occurs, all bistables trip, however NI indication is unchanged and remains "as-is". Therefore, this distractor is plausible.
However, the NI's have 3 diff erent power supplies that support various functions.
B. Correct.                   The first part is correct. See the first part of choice A above.
If a loss of control pow er only occurs, all bistables trip, however NI in dication is unchanged and remains"as-is". Therefore, this distractor is plausible.B. Correct. The first part is correct. See the first part of choice A above.
The second part is correct. The loss of the High Voltage Power Supply will result in a complete loss of power to the SR NIs and indication will read bottom of scale.
The second part is corre ct. The loss of the High Voltage Power Supply will result in a complete loss of pow er to the SR NIs and indication will read bottom of scale.
C. Incorrect. Plausible. The first part is incorrect. Per TS 3.9.3 Bases, one SR NI can be powered from a Non-1E power supply provided the other SR NI is powered from it's normal 1E power supply in Mode 6. It is abnormal for a Safety-Related, Tech Spec required component to be powered from a non-1E power supply and be considered OPERABLE. It is reasonable for a candidate without knowledge of this specific exception to determine the LCO not met. Therefore, this distractor is plausible.

B 3.9.3 Nuclear Instrumentation  
Nuclear Instrumentation B 3.9.3 B 3.9 REFUELING OPERATIONS B 3.9.3 Nuclear Instrumentation BASES BACKGROUND             The source range neutron flux monitors are used during refueling operations to monitor the core reactivity condition. The installed source range neutron flux monitors (NI-0031 and NI-0032) are part of the Nuclear Instrumentation System (NIS). These detectors are located external to the reactor vessel and detect neutrons leaking from the core. Temporary neutron flux detectors which provide equivalent indication may be utilized in place of installed instrumentation.
 
The installed source range neutron flux monitors are fission chamber detectors. The detectors monitor the neutron flux in counts per second. The instrument range covers seven decades of neutron flux (1E-1 cps to 1E +6 cps) with a 2% instrument accuracy. The detectors also provide continuous visual indication in the control room.

    - ALB05-E02 SPENT FU EL PIT LO LEVEL is received.
K/A MATCH ANALYSIS The question tests the candidate's ability to predict the impact of low spent fuel pool level by having to recall the bases for TS 3.7.15 level. The candidate is also required to mitigate the consequence of the event through the selection of a makeup source by selecting the appropriate procedure section to perform.
    - Personnel in the FHB re port SFP level is slowly lowering.
EXPLANATION OF REQUIRED KNOWLEDGE Per ARP 17005-1, ALB05-E02 alarms at a Spent Fuel Pool Level of 217'-0". Reports from the field have verified and low and decreasing pool level. AOP 18030-C is entered to mitigate the event. Per step 6 of this procedure, makeup to the SFP per SOP 13719-1 is directed. The specific procedure section is not specified. The candidate must recognize that makeup due to leakage will be from the RWST and not the RMWST. This ensures SFP boron concentration will be maintained. This requirement is stipulated in SOP 13719-1 Precaution and Limitation 2.1.7 and in a CAUTION at the beginning of sections 4.2.3 and 4.2.4. These state that non-borated makeup is usually only allowed for normal evaporative level losses. Borated water sources are the preferred maekup source for abnormal or unexplained level losses. Objective LO-PP-25102-11 is utilized during LOIT to re-enforce the use of borated water sources only during leakage.
    - 18030-C, "Loss of Spent F uel Pool Level or Cooling," is entered.
With SFP level less than the Tech Spec limit of 217'-0", less than 23 feet of water exist over the spent fuel stored in the racks. Per TS 3.7.15 Bases, the minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident. The bases also discusses TS 3.7.15 water level as providing shielding to minimize general area dose and provide shielding during spent fuel movement.
Which one of the following completes the following statement?
ANSWER / DISTRACTOR ANALYSIS A. Correct.                The first part is correct. Per SOP 13719-1 Spent Fuel Pool Cooling and Purification System, makeup due to leakage is from a borated source.
The second part is correct. Per Technical Specification 3.7.15 Fuel Storage Pool Water Level bases, the minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident.
B. Incorrect. Plausible. The first part is correct. See the first part of choice A above.
The second part is incorrect. Per Technical Specification 3.7.15 Fuel Storage Pool Water Level bases, the minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident.
However, the bases also discusses the shielding function of the water, which is a more commonly known benefit. A candidate without adequate knowledge of the TS Bases, may conclude that iodine decontamination is not a factor at all for water level, Friday, February 21, 2014 3:41:24 PM                                                                  2

K/A MATCH ANALYSIS The question tests the candidate's ability to predict the impact of low spent fuel pool level by having to recall the bases for TS 3.7.
C. Incorrect. Plausible. The first part is incorrect. Per SOP 13719-1 Spent Fuel Pool Cooling and Purification System, makeup due to leakage is from a borated source. However, normally SFP makeup is made from either Demin Water or the RMWST since the level change is due to evaporative loss and the boron is left in solution. A candidate with inadequate knowledge of the purpose behind using the different sources would find it reasonable to makeup using a normal source. Therefore, this distractor is plausible.

Fuel Storage Pool Water Level B 3.7.15 B 3.7 PLANT SYSTEMS B 3.7.15 Fuel Storage Pool Water Level BASES BACKGROUND            The minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident. The specified water level shields and minimizes the general area dose when the storage racks are filled to their maximum capacity. The water also provides shielding during the movement of spent fuel.
 
A general description of the fuel storage pool design is given in the FSAR, Subsection 9.1.2 (Ref. 1). A description of the Spent Fuel Pool Cooling and Cleanup System is given in the FSAR, Subsection 9.1.3 (Ref. 2). The assumptions of the fuel handling accident are given in the FSAR, Subsection 15.7.4 (Ref. 3).

APPLICABLE            The minimum water level in the fuel storage pool meets SAFETY ANALYSES        the assumptions of the fuel handling accident described in Regulatory Guide 1.25 (Ref. 4). The resultant 2 hour thyroid dose per person at the exclusion area boundary is a small fraction of the 10 CFR 100 (Ref. 5) limits.
Early submittal 401-9 response:-Need to make sure Secti on 4.2.4 cannot be argued as a correct answer. 13719 and EOP caution say borated water "should" rather than "shall" be used.    -Having Keff requirements as a basis for the SFP waterlevel does not seem plausible. However, I think this
According to Reference 4, there is 23 ft of water between the top of the damaged fuel bundle and the fuel pool surface during a fuel handling accident. With 23 ft of water, the assumptions of Reference 4 can be used directly. In practice, this LCO preserves this assumption for the bulk of the fuel in the storage racks. In the case of a single bundle dropped and lying horizontally on top of the spent fuel racks, however, there may be < 23 ft of water above the top of the fuel bundle and the surface, indicated by the width of the bundle. To offset this small nonconservatism, the analysis assumes that all fuel rods fail, although analysis shows that only the first few rows fail from a hypothetical maximum drop.
 
The fuel storage pool water level satisfies Criterion 2 of 10 CFR 50.36 (c)(2)(ii).

Fuel Storage Pool Water Level B 3.7.15 Vogtle Units 1 and 2 B 3.7.15-1 Rev. 1-10/01 B 3.7  PLANT SYSTEMS B 3.7.15  Fuel Storage Pool Water Level BASES BACKGROUND The minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident. The specified water level shields and minimizes the general area dose when the storage racks are filled to their maximum capacity. The water also provides shielding during the movement of spent fuel. A general description of the fuel storage pool design is given in the FSAR, Subsection 9.1.2 (Ref. 1). A description of the Spent Fuel Pool Cooling and Cleanup System is given in the FSAR, Subsection 9.1.3 (Ref. 2). The assumptions of the fuel handling accident are given in the FSAR, Subsection 15.7.4 (Ref. 3). APPLICABLE The minimum water level in the fuel storage pool meets SAFETY ANALYSES the assumptions of the fuel handling accident described in Regulatory Guide 1.25 (Ref. 4). The resultant 2 hour thyroid dose per person at the exclusion area boundary is a small fraction of the 10 CFR 100 (Ref. 5) limits. According to Reference 4, there is 23 ft of water between the top of the damaged fuel bundle and the fuel pool surface during a fuel handling accident. With 23 ft of water, the assumptions of Reference 4 can be used directly. In practice, this LCO preserves this assumption for the bulk of the fuel in the storage racks. In the case of a single bundle dropped and lying horizontally on top of the spent fuel racks, however, there may be < 23 ft of water above the top of the fuel bundle and the surface, indicated by the width of the bundle. To offset this small nonconservatism, the analysis assumes that all fuel rods fail, although analysis shows that only the first few rows fail from a hypothetical maximum drop. The fuel storage pool water level satisfies Criterion 2 of  10 CFR 50.36 (c)(2)(ii). (continued)

EXPLANATION OF REQUIRED KNOWLEDGE Friday, February 21, 2014 3:43:48 PM                                                            1
Per TS 3.4.13, 150 gpd primary to secondary LEAKAGE through any one steam generator exceeds allowable RCS operational LEAKAGE. In this condidtion, a shutdown to Mode 3 in 6 hrs and Mode 5 in 36 hrs is required. This shutdown can be accomplished using either the guidance of 12004-C or 18013-C. The decision is based on the characteristics of the leak and directed out of 18009-C.
Per 18009-C, if the tube leak is <5gpm and changing at a rate of < 30 gpd/hr, then a shutdown per 12004-C is sufficiently aggressive. If the tube leak is >5gpm or <5 gpm but changing at a rate >30 gpd/hr, then a more agressive shutdown utilizing 18013-C is necessary to ensure the plant is shutdown before the leak propogates into a rupture.
The rate of change is determined using 1RE-0724, N-16 Rad Monitor and/or 1RE-0810, SJAE Exhaust Rad Monitor, whose rate of change indications become valid after 20 mintues.
This decission tree is a complex set encompassing steps 5 thru 10 of 18009-C and is often mis-navigated. A high level understanding of steps are required to ensure internal self-checking of this operational decision.
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is incorrect. Per TS 3.4.13, 150 gpd LEAKAGE in any steam generator exceeds the TS limit. Since both rad montiors have leakage below this value, the limit has not be exceeded. However, the threshold between a tube leak and a tube rupture is 120 gpm. Therefore, a candidate without sufficient knowledge of the TS limits could transpose in their minds the 120 and 150 values and conclude that the TS limit has been exceeded. Therefore, this distractor is plausible.
The second part is correct. Per 18009-C, with the leak rate <5 gpm and the rate of change > 30gpd/hr, a power reduction using 18013-C would be required.
B. Incorrect. Plausible. The first part is incorrect. See the first part of choice A above.
The second part is incorrect. Per 18009-C, with the leak rate
                                    <5 gpm and the rate of change > 30gpd/hr, a power reduction using 18013-C would be required. However, a candidate without specific knowledge of the procedure decision tree values could conclude that the leak rate (120 gpd = 0.0833 gpm) is not sufficiently large to justify such an aggressive shutdown as 18013-C. Therefore, this distractor is plausible.
C. Correct.                The first part is correct. Per TS 3.4.13, 150 gpd LEAKAGE in any steam generator exceeds the TS limit. Since both rad montiors have leakage below this value, the limit has not be exceeded.
The second part is correct. See the second part of choice A above.

Per TS 3.4.13, 150 gpd primary to se condary LEAKAGE through any one steam generator exceeds allo wable RCS operational LEAKAGE. In this condidtion, a shutdown to Mode 3 in 6 hrs and Mode 5 in 36 hrs is required. This shutdown can be accomplished using either t he guidance of 12004-C or 18013-C. The decision is based on the characteristics of the l eak and directed out of 18009-C.
Per 18009-C, if the tube leak is <5gpm and changing at a ra te of < 30 gpd/hr, then a shutdown per 12004-C is suffi ciently aggressive.
If the tube leak is >5gpm or <5 gpm but changing at a rate >30 gp d/hr, then a more agressive shutdown utilizing 18013-C is necessary to ensure the plant is shutdown befor e the leak propogates into a rupture.
The rate of change is de termined using 1RE-0724, N-16 Rad Monitor and/or 1RE-0810, SJAE Exhaust Rad Monitor, whose rate of change indications become valid after 20mintues.This decission tree is a complex set enco mpassing steps 5 thru 10 of 18009-C and is often mis-navigated. A high level understanding of steps are required to ensure internal self-checking of this operational decision.ANSWER / DISTRACTOR ANALYSISA. Incorrect. Plausible. The first part is incorrect. Per TS 3.4.13, 150 gpd LEAKAGE in any steam generator exceeds th e TS limit. Since both rad montiors have leakage below this value, the limit has not be exceeded. However, the thre shold between a tube leak and a tube rupture is 120 gpm.
Therefore, a candidate without sufficient knowledge of the TS lim its could transpose in their minds the 120 and 150 values and conclude that the TS limit has been exceeded. Therefore, this distractor is plausible.
The second part is correct. Pe r 18009-C, with the leak rate <5 gpm and the rate of change >
30gpd/hr, a po wer reduction using 18013-C wo uld be required.
B. Incorrect. Plausible. Th e first part is incorre ct. See the first part of choice A above.
The second part is incorrect.
Per 18009-C, with the leak rate
<5 gpm and the rate of cha nge > 30gpd/hr, a power reduction using 18013-C would be required. However, a candidate without specific knowledge of the procedure decision tree values could conclude that t he leak rate (120 gpd = 0.0833 gpm) is not sufficiently large to justify such an aggressive shutdown as 18013-C. Therefore, this distractor is plausible.C. Correct. The first part is corre ct. Per TS 3.4.
13, 150 gpd LEAKAGE in any steam generator exceeds th e TS limit. Since both rad montiors have leakage below this value, the limit has not be exceeded.The second part is correct. See the second part of choice A above.Friday, February 21, 2014 3:43:48 PM 2

EXPLANATION OF REQUIRED KNOWLEDGE The indications given are the symptoms of a loss of power to 125VDC bus 1AD1. All 'A' train 1E switchgear breakers will loose control power. As such, the breaker will remain in its current state without electrical protection and all handswitch indication lights will be de-energized. The MSIVs and MFIVs will fail CLOSED as their solenoids are de-energized resulting in a Reactor Trip.

Per Admin procedure 10020-C step 3.3, "Initiate" means the referenced procedure will be used as a supplement to, and it will be performed concurrently with the one in effect. Therefore, 18034-C and 19000-C are expected to be worked in conjunction due to the complications resulting from a loss of DC.
and make a decision on which procedures would address the problem. EXPLANATION OF REQUIRED KNOWLEDGE The indications given are the symptoms of a loss of power to 125VDC bus 1AD1. All 'A' train 1E switchgear breakers will loose contro l power. As such, the breaker will remain in its current state without el ectrical protection and all han dswitch indication lights will be de-energized. The MSIV s and MFIVs will fail CLOSED as their solenoids are de-energized resulting in a Re actor Trip. All Channel I TSLBs lights will illuminate due to the loss of 1AY1A, which is normally feed from an inverter supplied by 1AD1.
18034-1 will address all issues required by the loss of the supported 120V Vital AC bus.

B. Incorrect. Plausible. The first part is correct. Entry conditions for 18034-1 are met.
The second part is incorrect.
The second part is incorrect. Per step 1 RNO of 18034-1, a reactor trip should have occured and is required. However, step 1 is not an IOA. A candidate without specific knowledge of the procedure and who did not realize the MISIVs could conclude the reactor did not trip and entry into 19000-C is not required. Therefore, this distractor is plausible.

However, a candidate with insufficient knowledge of power supplies could conclude that the handswitches are feed from 120V Vital AC and not the 125VDC supply. This is a common misconception. As such, it would be reasonable for the candidate to conclude a loss of 1AY1A to have occurred and entry into 18034-1 is not required. Therefore, this distractor is plausible.
The second part is correct. Step 1 of 18034-1 directs a reactor trip and INITIATION of 19000-C. However, a candidate that believes 18032-1 was entered instead of 18034-1, would still find it reasonable that the reactor would trip based on other trips. Therefore, this distractor is plausible.
D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

The second part is incorrect. Step 1 of 18034-1 directs a reactor trip and INITIATION of 19000-C. However, a candidate that believes 18032-1 was entered instead of 18034-1 and has knowledge of 18032-1, would not expect the reactor to trip.
Therefore, this distractor is plausible.
SRO JUSTIFICATION (10CFR43(b))
The second part is correct. Step 1 of 18034-1 directs a reactor trip and   INITIATION of 19000-C. Howeve r, a candidate that believes 18032-1 was entered in stead of 18034-1, would still find it reasonable that the reactor would trip based on othertrips. Therefore, this distractor is plausible.

        -Can the question be answered solely by knowing immediate operator actions?
No, the direction to initiate 19000-C concurrent with 18034-C is the RNO of step 1 of 18034-C and is not an IOA.
        -Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, the entry condition for each AOP/EOP is part of the question. However, the specific knowledge of 18034-C step 1 RNO is required. Normally, AOP use is discontinued upon entry into 19000-C. Most AOPs that direct tripping the reactor say "go to 19000-C", indicating that a transition to the EOP network is made. There are only a select few AOPs that required concurrent implementation of the AOP with the EOP. In most situation, the AOP is only performed at SS discretion and is typically not needed. 19000-C is designed to be successful with only one train of electrical power.
        -Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, specific knowledge of 18034-C step 1 RNO is required.
        -Does the question require one or more of the following?
* Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed. Yes, the candidate is required to select the appropriate procedure/combination of procedures to mitigate the plant conditions.
* Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps
* Knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific subprocedures or emergency contingency procedures

K/A MATCH ANALYSIS The question tests the candidates knowledge of generic TS survelliance SR 3.0.3 as specifically applied to a missed NSCW survelliance. If the missed survelliance results in an inoperable declaration, a loss of one train of NSCW would occur since the survelliance affects the Ultimate Heat Sink LCO 3.7.8.
EXPLANATION OF REQUIRED KNOWLEDGE A Surveillance has been identified on an NSCW System as being missed and the candidate must use Tech Spec SR 3.0.3 to determine when the missed surveillance is to be performed by. If it is discovered that a Surveillance was not performed within its specified Frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours or up to the limit of the specified Frequency, whichever is greater. This delay period is permitted to allow Monday, February 24, 2014 9:43:58 AM                                                            1


To prevent declaring the LC O NOT met, the surveillance is required to be performed satisfactorily no later than ________.

If the Surveillance is not performed within the delay period, the LCO must immediately be declared not met, and the applicable Condition(s) must be entered.
0030 on 5-12-14
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Incorrect but plausible because the candidate may determine the surveillance must be perform within 24 hours of the time missed as opposed to time of discovery.
 
B. Incorrect. Plausible. Incorrect but plausible because the candidate may determine the surveillance must be perform from time missed within 24 hours plus the 125% grace period described in SR 3.0.2. The specified Frequency for each SR is met if the Surveillance is performed within 1.25 times the interval specified in the Frequency, as measured from the previous performance or as measured from the time a specified condition of the Frequency is met.

C. Correct.                 The answer is correct the missed surveillance must be completed within 24 hours of point of discovery. (e.g. If it is discovered that a Surveillance was not performed within its specified Frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours or up to the limit of the specified Frequency, whichever is greater. This delay period is permitted to allow performance of the Surveillance. A risk evaluation shall be performed for any Surveillance delayed greater than 24 hours and the risk impact shall be managed.

In addition, the candidates must determine the impact on plant operations using the information provided in the stem as related to LOSF evaluation. This concept brings the question to the SRO knowledge level.
    - Train 'B' NSCW s upply header flow is 25,000 gpm.     - Train 'B' NSCW re turn header flow is 10,000 gpm.
EXPLANATION OF REQUIRED KNOWLEDGE Per 18021-C symptoms, a drop in NSCW header pressure accompanied by a large difference between supply and return header flows indicates a large (catastrophic) leak.
    -  18021-C, "Loss of Nuclear Service Cooling Water System," is entered.
Per steps 1 and 2, all pumps in the affected train will be placed in PTL.
Which one of the following completes the following statement?
Since NSCW 'B' is a support system for all 'B' train ECCS pumps, a LOSF function exists with SIPs. With SIP 'A' tagged out in the stem and a subsequent loss of SIP 'B' due to loss of a support system, no medium head injection is available. Since TS 3.5.2 does not have a condition for two trains of ECCS inoperable, TS 3.0.3 must be entered.
(Reference 10008-C for LOSF evaluation guidance.)
ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is incorrect however plausible since the candidate may believe the stem indications are due a pump problem such as a broken coupling, as opposed to a leak since the symptoms would be the same with exception of the supply and return flow deviation. Per 18021-C step 6, the correct action for this condition would be to start the standby pump.
Part 2 is correct. The candidate should determine that with both Train A SI Pump and Train B NSCW System inoperable a LOSF exists per 10008-C 'Recording Limiting Conditions for Operation'. However, if the candidate misses the catastrophic leak in Part 1, it would still be plausible for them to incorrectly determine that the standby NSCW pump is inoperable due to the failure to start on low header pressure and determine a LOSF exists for the wrong reason.
B. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice A above.
Part 2 is incorrect. The candidate should determine that with both Train A SI Pump and Train B NSCW System inoperable a LOSF exists per 10008-C 'Recording Limiting Conditions for Operation'. However, if the candidate misses the catastrophic leak in Part 1 and recognizes that the failure of the start on low header pressure in not a required function, then determining that a LOSF does not exist would be correct for these erroneous conditions..
C. Correct.                  Part 1 is correct. The candidate should determine that from the stem information provided that a large leak has occurred in the NSCW piping and the correct actions per 18021-C Loss of NSCW, is to place the affected pumps in PTL.

Part 2 is incorrect however 'pl ausible' since the candidate maynot make the operability connection between the two systems
Part 2 is incorrect however plausible since the candidate may not make the operability connection between the two systems or assume that NSCW could be run in single pump operations to supply cooling and therefore believe a LOSF condition is not present.

Stanley                      Vogtle Electric Generating Plant                        10008-C      30 Effective Date                                                                              Page Number 02/08/2013                    RECORDING LIMITING CONDITIONS FOR OPERATION                            3 of 32 1.0                PURPOSE 1.1                This procedure prescribes the method to record the failure to meet the Limiting Conditions for Operation (LCO), or Technical Requirement, the associated ACTION requirements, any change in status effecting the ACTION, and the return to compliance with LCO/TR.
2.0 PRECAUTIONS AND LIMITATIONS 2.1 Technical Specification LCO 3.0.2 stat es that the required Actions of an LCO MUST be performed when the requirements of the LCO are NOT met. LCO 3.0.6 provides an exception to LCO 3.0.2 for SUPPORTED SYSTEMS by NOT requiring the Required Actions for the SUPPORTED SYSTEMS to be performed WHEN the failure to meet an LCO is SOLELY due to the inoperability of a SUPPORT SYSTEM. In th is situation, LCO 3.0.6 requires ONLY the Required Actions of the SUPPORT SYSTEM to be performed. Since "cascading" is NOT required in this ca se, a possibility exists that unrelated concurrent failures of more than one SUPPORT SYSTEM could result in the complete loss of both trains of a SUPPORTED SYSTEM. THEREFORE, upon a failure to meet two or more LCOs during the same time period, an evaluation SHALL be conducted to determine if a LOSS OF SAFETY FUNCTION (LOSF) exists. This LOSF Evaluation satisfies t he criteria of Technical Specification Administrative Control 5.5.15, Sa fety Function Determination Program.  
1.2                This procedure also includes instructions for implementing Technical Specification 5.5.15, the Safety Function Determination Program. As required by LCO 3.0.6, this program ensures that proper actions are taken such that multiple inoperable Structures, Systems, or Components (SSC) do not result in an undetected LOSS OF SAFETY FUNCTION.
1.3               This procedure also ensures that the allowed out of service time of SUPPORTED SYSTEMS is not inappropriately extended as a result of multiple inoperable SUPPORT SYSTEMS.
2.0               PRECAUTIONS AND LIMITATIONS 2.1               Technical Specification LCO 3.0.2 states that the required Actions of an LCO MUST be performed when the requirements of the LCO are NOT met. LCO 3.0.6 provides an exception to LCO 3.0.2 for SUPPORTED SYSTEMS by NOT requiring the Required Actions for the SUPPORTED SYSTEMS to be performed WHEN the failure to meet an LCO is SOLELY due to the inoperability of a SUPPORT SYSTEM. In this situation, LCO 3.0.6 requires ONLY the Required Actions of the SUPPORT SYSTEM to be performed. Since cascading is NOT required in this case, a possibility exists that unrelated concurrent failures of more than one SUPPORT SYSTEM could result in the complete loss of both trains of a SUPPORTED SYSTEM. THEREFORE, upon a failure to meet two or more LCOs during the same time period, an evaluation SHALL be conducted to determine if a LOSS OF SAFETY FUNCTION (LOSF) exists. This LOSF Evaluation satisfies the criteria of Technical Specification Administrative Control 5.5.15, Safety Function Determination Program.
2.2                If the failure of a SSC not addressed by Technical Specification results in the inoperability of a required SUPPORT and/or SUPPORTED SYSTEM, then the LCO(s) for the required SUPPORT and/or SUPPORTED SYSTEM would be entered. Example: If 1NB10 is de-energized, the operability of D/G '1B' or the Pressurizer Heaters may be impacted.
2.3                A single component inoperability can result in multiple inoperabilities within a single train and affect multiple Technical Specification LCOs. LCO 3.0.6 limits the amount of "cascading" of actions that is required when an inoperable SSC renders a SUPPORT SYSTEM inoperable.

Timely RCS activity sampling following a power reduc tion of more than 15% in o ne hour is required verify no fuel damage, which leads to high coolant activity. Then the candidate must determine the Tech Spec bases for loweri ng the energy level in the RCS if limits are exceeded. EXPLANATION OF REQUIRED KNOWLEDGE TS SR 3.4.16.2 requires veri fication of DOES EQ UIVALENT I-131 specific activity less than or equal to 1.0 uCi/gm between 2 and 6 hours follo wing a power change of greater than or equal to 15% RTP within a 1 hr period. By definiti on, the 1 hr period is a rolling hour. As stated in the stem , the power change between 1100 and 1200 is 14%RTP.

RCS specific activity satisfies Criterion 2 of 10 CFR 50.36 (c)(2)(ii).
LCO          The specific iodine activity is limited to 1.0 Ci/gm DOSE EQUIVALENT I-131, and the gross specific activity in the reactor coolant is limited to the number of Ci/gm equal to 100 divided by (average disintegration energy of the sum of the average beta and gamma energies of the coolant nuclides). The limit on DOSE EQUIVALENT I-131 ensures the 2 hour thyroid dose to an individual at the exclusion area boundary during the Design Basis Accident (DBA) will be a small fraction of the allowed thyroid dose. The limit on gross specific activity ensures the 2 hour whole body dose to an individual at the exclusion area boundary during the DBA will be a small fraction of the allowed whole body dose.
The SGTR accident analysis (Ref. 2) shows that the 2 hour site boundary dose levels are within acceptable limits. Violation of the LCO may result in reactor coolant radioactivity levels that could, in the event of an SGTR, lead to exclusion area boundary doses that exceed the 10 CFR 100 dose guideline limits.
APPLICABILITY In MODES 1 and 2, and in MODE 3 with RCS average temperature t 500qF, operation within the LCO limits for DOSE EQUIVALENT I-131 and gross specific activity are necessary to contain the potential consequences of an SGTR to within the acceptable site boundary dose values.
For operation in MODE 3 with RCS average temperature < 500qF, and in MODES 4 and 5, the release of radioactivity in the event of a SGTR is unlikely since the saturation pressure of the reactor coolant is below the lift pressure settings of the main steam safety valves.

The candidate must determine if this is intrusive or non-intrusive trouble shootin g and also has to determine the person responsible formaintaining the system status of the panel during Trouble Shooting activities.EXPLANATION OF REQUIRED KNOWLEDGE Per NMP-AD-002 definition 3.
A. Incorrect. Plausible. Part 1 is correct. Opening breakers by Operations and opening links by Maintenance is an intrusive troubleshooting per NMP-AD-002.
5, non-intrusive monitoring is defined as the act ofmonitoring a component or system by not affecting normal oepration of the conponent
Part 2 is incorrect. Operations Department is responsible for tracking systems status, however the answer is 'plusable' because opening links, measuring resistance, etc. would all be maintenance activities and some amount of individual component status control is required. These components are typically tracked using a "lifted lead" sheet inside the MWO.
 
Even though maintenance tracks status of some components, Operations still retains overall responsibility for ensuring equipment status and configuration control.
or system.
B. Correct.                  Part 1 is correct. See Part 1 of choice A above.
Per NMP-AD-002 definition 3.6, intrusive monitoring is defined as the act of temporarilyaltering the system to allow monitoring a component or system. This applies to electrical or mechani cal testing methods.

Tech Spec action is required for RWST __(1)__,
EXPLANATION OF REQUIRED KNOWLEDGE Per TS SR 3.5.4.1, the RWST borated water temperature must be maintained greater than or equal to 44&deg;F and less than or equal to 116&deg;F. Per TS 3.5.4 Bases, the maximum temperature ensures that the amount of cooling provided from the RWST during the heatup phase of a feedline break is consistent with the safety analysis assumptions. The minimum temperature is an assumption in both the MSLB and inadvertent ECCS actuation. The inadvertent ECCS actuation is typically non-limiting.
and the Tech Spec Basis for this param eter limit is to ensure __(2)__.
Per TS SR 3.5.4.1, the RWST borated water must be maintained greater than or equal to 686,000 gallons. Per Tech Spec rounds OSP 14000-1, 686,000 gallons corresponds to an indicated level of 94%. Per TS 3.5.4 Bases, the RWST volume is an explicit assumption for LOCA events. The desired volume limit is set by LOCA and containment analyses. The volume is not an explicit assumption for non-LOCA events since the required volume is a small fraction of the available volume. The deliverable volume is different from the total volume contained since, due to the design of the tank, more water can be maintained than can be delivered.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is correct. 93% level will place the unit in a 1 hour shutdown.
Once determining RWST level is the 1 hour shutdown, the SRO portion requires the candidate to know the correct bases fo r the RWST level.Tuesday, February 25, 2014 11:49:11 AM 1
The second part is incorrect. RWST level ensures sufficient injection volume for a DBA LOCA, not a DBA MSLB. However, Safety Injection is required to mitigate a main steam line break and requires suction from the RWST, but is not a limiting factor since the required volume would be a small fraction of that available.

Time of Condition A or D
RWST B 3.5.4 BASES BACKGROUND          reduction of SDM or excessive boric acid precipitation in the core (continued)      following the LOCA, as well as excessive stress corrosion of mechanical components and systems inside the containment.
APPLICABLE          During accident conditions, the RWST provides a source of SAFETY ANALYSES      borated water to the ECCS and Containment Spray System pumps.
As such, it provides containment cooling and depressurization, core cooling, and replacement inventory and is a source of negative reactivity for reactor shutdown (Ref. 1). The design basis transients and applicable safety analyses concerning each of these systems are discussed in the Applicable Safety Analyses section of B 3.5.2, "ECCS  Operating"; B 3.5.3, "ECCS  Shutdown"; and B 3.6.6, "Containment Spray and Cooling Systems." These analyses are used to assess changes to the RWST in order to evaluate their effects in relation to the acceptance limits in the analyses.
The RWST must also meet volume, boron concentration, and temperature requirements for non-LOCA events. The volume is not an explicit assumption in non-LOCA events since the required volume is a small fraction of the available volume. The deliverable volume limit is set by the LOCA and containment analyses. For the RWST, the deliverable volume is different from the total volume contained since, due to the design of the tank, more water can be contained than can be delivered. The minimum boron concentration is an explicit assumption in the main steam line break (MSLB) analysis to ensure the required shutdown capability. The maximum boron concentration is an explicit assumption in the inadvertent ECCS actuation analysis, although it is typically a nonlimiting event and the results are very insensitive to boron concentrations. The maximum temperature ensures that the amount of cooling provided from the RWST during the heatup phase of a feedline break is consistent with safety analysis assumptions; the minimum is an assumption in both the MSLB and inadvertent ECCS actuation analyses, although the inadvertent ECCS actuation event is typically nonlimiting.
The MSLB analysis has considered a delay associated with the interlock between the VCT and RWST isolation valves, and the (continued)

not met. E.1  Be in MODE 3.  
RWST B 3.5.4 BASES APPLICABLE          results show that the departure from nucleate boiling design SAFETY ANALYSES      basis is met. The delay has been established as 27 seconds, (continued)      with offsite power available, or 39 seconds without offsite power (includes 12 seconds for the Emergency Diesel Generator). This response time includes an electronics delay, a stroke time for the RWST valves, and a stroke time for the VCT valves.
 
For a large break LOCA analysis, the minimum water volume limit of 499,091 gallons and the lower boron concentration limit of 2400 ppm are used to compute the post LOCA sump boron concentration necessary to assure subcriticality. The large break LOCA is the limiting case since the safety analysis assumes that all control rods are out of the core.
AND E.2  Be in MODE 5.  
The upper limit on boron concentration of 2600 ppm 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.
 
In the ECCS analysis, the containment spray temperature is assumed to be equal to the RWST lower temperature limit of 44qF. If the lower temperature limit is violated, the containment spray further reduces containment pressure, which decreases the rate at which steam can be vented out the break and increases peak clad temperature. (The reduction in containment pressure correspondingly reduces the density of the vented steam. This reduces the flow of steam out of the core, which translates into a decrease in the ECCS flooding rate. This decrease in the flooding rate causes the increase in peak clad temperature.) The upper temperature limit of 116qF is used in the small break LOCA analysis and containment OPERABILITY analysis.
6 hours
Exceeding this temperature will result in a higher peak clad temperature, because there is less heat transfer from the core to the injected water for the small break LOCA and higher containment pressures due to reduced containment spray cooling capacity. For the containment response following an MSLB, the lower limit on boron concentration and the upper limit on RWST water temperature are used to maximize the total energy release to containment.
 
The RWST satisfies Criterion 3 of 10 CFR 50.36 (c)(2)(ii).

K/A G2.3.7          Radiation Control Ability to comply with radiation work permit requirements during normal or abnormal conditions:
K/A MATCH ANALYSIS:
The candidate is presented with a scenario where an Auxiliary Building Operator is required to enter several rooms with high dose rates in the area. The Operator is also on the verge of exceeding his Annual TEDE limits of 4000 mrem. The candidate has to determine the minimum level of authority that may approve exceeding the annual TEDE limits.
EXPLANATION OF REQUIRED KNOWLEDGE Per NMP-HP206 step 5.3.31.2 states that RED RWPs are "Single Use" type briefings.
Step 5.3.11.1.4 defines Single Use as "individuals must be authorized and the authorization is good for one entry only."
Per NMP-HP-001 step 6.2.3, there are 3 different administrative levels that require 3 different levels of approval:
: 1. 2000 mrem in a year requires HP Supervisor, Physicist, or Manager approval.
: 2. 4000 mrem in a year requres AGM or Plant General Manager approval.
: 3. 4500 mrem in a year requires Project Vice President approval.
Dose in excess of 5mrem requires special NRC approval for normal operation, ED approval during emergencies. These different admin limits do not have a noun description/name and therefore are generally referred to by the associated dose limit.
DISTRACTOR ANALYSIS:
A. Incorrect. Plausible. Part 1 is correct. RWP 14-0108 is a red RWP and therefore requires a Single Use briefing on each entry per NMP-HP-206.
Part 2 is incorrect. Per NMP-HP-001, exceeding the 4000mrem per year admin dose limit will required Plant General Manager approval. However, the HP Supervisor can approval all dose up to the 4000mrem limit. Therefore, this distractor is plausible.
B. Correct.                  Part 1 is correct.RED RWP and requires a briefing for each entry. The minimum authority level to approve the TEDE extension is the Plant Manager from the choices presented.
Part 2 is correct. Per NMP-HP-001, exceeding the 4000mrem per year admin dose limit will required Plant General Manager approval.

6.2.3.3 4500 mrem in a year requires Project Vice President approval.
6.2.4 Discrepant Dosimeter Investigation Criteria An assessment of worker's dose should be initiated for discrepant dosimetry results when the following criteria are met: the primary or secondary dosimeter dose exceeds 100 mrem; and the secondary dosimeter reading differs by more than 25% from the primary dosimeter.
 
6.2.5 Dose Monitoring Threshold All individuals entering an RCA will be monitored for radiation exposure. A single dosimeter suffices for Visitors or Radiation Workers whose annual dose from sources external to the body is not expected to exceed 100 mrem at a particular station. An Optically Stimulated Luminescent Dosimeter (OSLD) and a self-reading dosimeter, such as an Electronic Dosimeter (ED), will be provided to all other individuals.
6.2.6 Training Requirements for Visitors or Temporary Radiation Workers Who Enter RCAs All SNC plants will administer training to all who must enter the RCAs in the following manner:  6.2.6.1 If the individual is expected to receive < 100 mrem in a year, the individual will be escorted by a GET qualified worker and will be provided instructions.
 
6.2.6.2 If the individual is expected to receive >100 and <500 mrem in a year, the individual will receive a visitor handout (containing all of the instruction elements required by 10CFR19.12) and will acknowledge receipt of the instructions or handout by signing a form. The individual will have a GET-trained radiological escort. If special circumstances dictate that entries into contaminated areas are required, the individual will receive dress-out training (if he has no history of such training at our plants). Similarly, if the individual requires entry to high radiation areas, special training or instructions may be required.
 
6.2.6.3 If the individual is expected to receive >=500 mrem in a year, the individual is required to complete GET which includes testing. If the individual has previous GET training at a nuclear facility within the past two years or as allowed by the Training Department, then exemption GET and the exemption GET test can be administered.
6.2.7 Air Flow for Fume Hoods Containing Radioactive Materials/Fluids Sample station fume hoods containing radioactive materials/fluids will meet a minimum air flow acceptance criteria of 100 LFPM, and will be labeled to ensure that 100 LFPM is maintained or exceeded.

A. Incorrect. CA3 is a Cold Matrix classification, the plant is in Mode 4, not Mode 5 or 6. The mode was NOT stated in the question but just an RCS temperature given to increase the plausibility the candidate may select the wrong classification matrix. If the candidate selects the wrong matrix with the given alarms, it is plausible he could misinterpret the event and classify wrong. With the multiple alarms and indications, this can easily occur.
Based on the current time, which one of the following is the correct Emergency Classification required to be declared?REFERENCE PROVIDED Alert Emergency (CA3)
B. Correct. SA5 is the correct classification using the Hot Matrix, this is still a difficult determination with the multiple annunciator windows illuminated. The plant is only one failure away from a total plant blackout in this condition but the candidate has to determine this and correlate the event has been ongoing for > 15 minutes.
Alert Emergency (SA5)
C. Incorrect. SU1 is a Hot Matrix classification. The plant is only one failure away from a total plant blackout in this condition but the candidate has to determine this and correlate the event has been ongoing for > 15 minutes. This choice is very plausible as the only difference between this and SA5 is that both diesels have to be carrying the buses to classify as SU1 versus 1 DG as in the correct choice.
Notification of U nusual Event (SU1)
This is a difficult determination with the mulitiple annuciators illuminated.
Notification of U nusual Event (CU3)
D. Incorrect. CA3 is a Cold Matrix classification, the plant is in Mode 4, not Mode 5 or 6. The mode was NOT stated in the question but just an RCS temperature given to increase the plausiblity the candidate may select the wrong classification matrix. IF, the plant were in Mode 5 and the Cold Matrix required to be used, this choice would then be correct.

==REFERENCES:==
The candidate is given various alarms and indications associated with the electricaldistribution system. The candidate has to analyze the alarms to determine the plant status and determine the correct emergency cl assification, there is a time given when the event occurred that will also play into the classification.
The question is SRO only due to the Vogtle specific objective for Classification of an Emergency is an SRO only objective.Tuesday, January 21, 2014 4:27:30 PM 1
ANSWER / DISTRACTOR ANALYSIS:A. Incorrect. CA3 is a Cold Matrix classi fication, the plant is in Mode 4, not Mode 5 or 6. The mode was NOT stated in t he question but just an RCS temperature given to increase the pl ausibility the candidate may select the wrong      classification matrix. If the candidate selects the wrong matrix with the given alarms,    it is plausible he c ould misinterpret the event and cl assify wrong. With the multiple alarms and indication s, this can easily occur.
B. Correct. SA5 is the correct classification using t he Hot Matrix, this is still a difficult determination wi th the multiple annunciator window s illuminated. The plant is only one failure away from a total plant blackout in this condition but the candidate has to determine this and co rrelate the event has been ongoing for > 15 minutes.
C. Incorrect. SU1 is a Hot Ma trix classification. The plant is only one failure away from a total plant blackout in this condi tion but the candidate has to determine this and correlate the even t has been ongoing for
> 15 minutes. This choice is very plausible as the only difference between this and SA5 is t hat both diesels have to be carrying the buses to classify as SU1 versus 1 DG as in the correct choice.
This is a difficult determination with the mulitip le annuciators illuminated.

The question requires the candidate to make two decisions based on plant conditions while in 19111-C, "Loss of Emergency Coolant Recirculation" - stopping all ECCS pumps and transitioning out of 19111-C. Both decisions challenge the candidate's ability to adhere to the rules for using EOPs in compliance with WOG and facility requirements. Actions taken in accordance with these EOPs are part of the bases for granting the facility's license.

Transition to any ORANGE or RED CSFST will be made when conditions are met. Per the rules of EOP usage, CSFSTs are initiated when either step 22 of 19000-C is reached, or a transition out of 19000-C is made. CSFSTs remain in effect during the entire EOP network unless otherwise directed. 19111-C does NOT contain any exceptional guidance on CSFST implementation.

The first part is correct. Per continuous actions step 6 and steps 33 and 34, if RWST lowers to <8%, all ECCS pumps taking suction from the RWST are placed in PTL.
ANSWER / DISTRACTOR ANALYSIS A. Correct.                   The first part is correct. Per continuous actions step 6 and steps 33 and 34, if RWST lowers to <8%, all ECCS pumps taking suction from the RWST are placed in PTL.
The second part is correct. CSFS T monitoring was initiated on transition out of 19000-C. Ther e is no guidance in 19111-C that prohibits actions based on CSFSTs. Therefore, a transition to 19241-C will be made as soon as ORANGE path conditions areverified.B. Incorrect. Plausible. Th e first part is incorre ct. Per continuous actions step 6 and steps 33 and 34, if RWST lowers to <8%, all ECCS pumps taking suction from the RWST are to be placed in PTL.
The second part is correct. CSFST monitoring was initiated on transition out of 19000-C. There is no guidance in 19111-C that prohibits actions based on CSFSTs. Therefore, a transition to 19241-C will be made as soon as ORANGE path conditions are verified.
However, step 15 does reduce ECCS flow to only one train. This is a mitigation strategy that prolongs RWST inventory. A candidate who does not possess the knowledge of the overall mitigating strategy of 19111-C could find it unreasonable to stop all ECCs pumps with a LOCA in progress and then transition to another procedure that does not address loss of injection flow.

Initial conditions:

- Unit 1 is at 70% reactor power.

- Main Turbine load is stable.

- Rods are in automatic with CBD at 190 steps.

- Control rods start stepping out without demand.

Current conditions:

- Rod motion stops when the Rod Bank Selector Switch is placed in Manual.

- Reactor power indication has risen to 75%.

- CBD rods are at 211 steps, EXCEPT control rod H8, which is at 190 steps by DRPI indication.

With NO other actions taken, which one of the following completes the following statement?

- Reactor power and its trend Thursday, February 20, 2014 8:28:29 AM 1

K/A MATCH ANALYSIS The question sets up a plausible scenario where rods withdrawal due to some internal failure inserts some amount of positive reactivity. Once operator action is taken rod motion stops and the candidate must address how the core will respond to the inserted reactivity and the impact of the stuck rod, therefore the two elements are in place that the KA requires. The OPERABILITY determination for the affect rod is SRO required knowledge.

EXPLANATION OF REQUIRED KNOWLEDGE As control rods are withdrawn, an increase in fission rate will occur. The resulting fuel centerline temperature increase from the positive reactivity addition will be offset by FTC and MTC feedback. As a result, reactor power will trend down toward the orginial power level with and increase RCS average temperature. Since RCS temperature is higher than the orginial temperature, SG pressure will also be slightly elevated. The higher SG pressure will result in slight increase in steam flow as compared to the original conditions. Therefore, reactor power will be slightly higher than the pre-transient value. This is a fundamental reactor theory concept.

Per TS 3.1.4 Bases, the OPERABILITY requirements (i.e. trippability) are seperate from the alignment requirements. Even if a rod is >12 steps misaligned, it is still OPERABLE.

Where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. Since rod motion was demanded and did not occur and there is nothing given in the stem to explain the loss of motion, the candidate must declare rod H8 inoperable.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is 'plausible' however incorrect in that the candidate may determine that reactor power will rise to a new higher equilibrium value and stabilize. Thus, the candidate failed to take into count the reactivity feedback mechanisms of MTC and FTC on core behavior. In addition, the answer would be correct under some plant condition like during startup steam dumps in steam pressure mode.

Part 2 is 'plausible' but is also incorrect in that the candidate must consider the affected rod inoperable until proven trippable as stated in Tech Spec 3.1.4 Rod Group Alignment Limits bases; However, where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. If the rod control system is demanding motion properly and no motion occurs, the rod is considered untrippable (i.e., inoperable). This operability call is contrary to the standard philosophy that a component is considered OPERABLE until determined otherwise.

B. Incorrect. Plausible. Part 1 is 'plausible' however incorrect. See Part 1 of choice A above.

Thursday, February 20, 2014 8:28:29 AM 2

Part 2 is correct requiring the candidate to recall Tech Spec 3.1.4 Rod Group Alignment Limits bases which ties OPERABILITY to trippability of the rods. The rod OPERABILITY (i.e., trippability) requirement is satisfied provided that the rod will fully insert in the required rod drop time assumed in the safety analyses. Rod control malfunctions that result in the inability to move a rod (e.g., rod lift coil failures), but that do not impact trippability, do not result in rod inoperability. However, where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. If the rod control system is demanding motion properly and no motion occurs, the rod is considered untrippable (i.e., inoperable).

C. Incorrect. Plausible. Part 1 is correct which is addressing core response and correctly predicts that the positive reactivity will be offset by FTC and MTC feedback. Over time the reactor power will lower to near original values, only slightly higher due to TAVG being raised which results in an increase in Steam Generator pressure. This would result in a small increase in steam flow.

Part 2 is 'plausible' but is also incorrect. See Part 2 of choice A above.

D. Correct. Part 1 is correct. See Part 1 of choice C above.

Part 2 is correct. See Part 2 of choice B above.

1. 005AG2.1.07 001/1/2/STUCK CRDM/C/A - 4.4/4.7/BANK-HL-17/HL-18 NRC/SRO/AML Initial conditions: Original Question

Rod Group Alignment Limits B 3.1.4 BASES (continued)

LCO The limits on shutdown or control rod alignments ensure that the assumptions in the safety analysis will remain valid. The requirements on OPERABILITY ensure that upon reactor trip, the assumed reactivity will be available and will be inserted. The OPERABILITY requirements (i.e., trippability) are separate from the alignment requirements which ensure that the RCCAs and banks maintain the correct power distribution and rod alignment.

The rod OPERABILITY (i.e., trippability) requirement is satisfied provided that the rod will fully insert in the required rod drop time assumed in the safety analyses. Rod control malfunctions that result in the inability to move a rod (e.g., rod lift coil failures), but that do not impact trippability, do not result in rod inoperability. However, where rod(s) are not moving, the rod(s) must be considered untrippable unless there is verification that a rod control system failure is preventing rod motion. If the rod control system is demanding motion properly and no motion occurs, the rod is considered untrippable (i.e.,

inoperable).

The requirement to maintain the rod alignment to within plus or minus 12 steps of their group step counter demand position is conservative. The safety analysis assumes a total misalignment from fully withdrawn to fully inserted. When required, movable incore detectors may be used to determine rod position and verify the rod alignment requirement of this LCO is met.

Failure to meet the requirements of this LCO may produce unacceptable power peaking factors and LHRs, or unacceptable SDMs, all of which may constitute initial conditions inconsistent with the safety analysis.

APPLICABILITY The requirements on RCCA OPERABILITY and alignment are applicable in MODES 1 and 2 because these are the only MODES in which a self-sustaining chain reaction (Keff t 1) occurs, and the OPERABILITY (i.e., trippability) and alignment of rods have the potential to affect the safety of the plant. In MODES 3, 4, 5, and 6, the alignment limits do not apply because the control rods are fully inserted and the reactor is shut down, with no self-sustaining chain reaction. In the shutdown MODES, the OPERABILITY of the shutdown and control rods has the potential to affect the required SDM, but this effect can be compensated for by an increase in the boron concentration of the RCS. See LCO 3.1.1, "SHUTDOWN MARGIN (SDM)," for SDM in MODES 3, 4, and 5 and LCO 3.9.1, "Boron Concentration," for boron concentration requirements during refueling.

K/A MATCH ANALYSIS The question test the candidate ability to evaluate and validate a plant computer (IPC) generated alarm for the current plant conditions associated with the Rod Control system. Then the SRO is required to determine if control rod withdrawal is both prudent and allowed under the stated conditions in the stem per the NMP-OS-001 Reactivity Management Program.

Thursday, February 20, 2014 8:45:05 AM 1

EXPLANATION OF REQUIRED KNOWLEDGE The IPC calculates the rod insertion limit using real time data. When the alarm is generated the candidate would be expected to verify the validity of the alarm. This evaluation would be accomplished using IPC and Tech Spec data with backup from QMCB indications. In addition, the Shift Supervisor is required the make a decision to withdrawal control rods based on NMP-OS-001 Reactivity Management Program guidance.

The control room team shall not immediately dilute or withdraw control rods in an attempt to restore RCS Tavg/Tref deviations caused by a secondary plant transient.

Attempts to immediately restore RCS Tavg/Tref deviations caused by a secondary plant transient can be aggravated by withdrawing control rods or reducing boron concentration with reactor power rising. Per NMP-OS-001, once turbine load has been stabilized and RCS Tavg has been restored to within 3°F of Tref, positive reactivity can be added by withdrawing control rods.

ANSWER / DISTRACTOR ANALYSIS A. Correct. The first part is correct. Per the IPC printout, RCS DeltaT Power is approximately 83% and CBD position is 116 steps.

The IPC uses Auctioneered High DeltaT Power for the RIL calculation. Per the COLR, the RIL for 83% power is 122 steps on CBD. Therefore, ALB10-D04 is a valid alarm.

The second part is correct. Per NMP-OS-001 step 6.1.2.4, once turbine load has been stabilized and RCS Tavg has been restored to within 3° of Tref, positive reactivity can be added by withdrawing control rods. Both of these conditions have been met. Therefore, control rod withdrawal is not restricted.

B. Incorrect. Plausible. The first part is correct. See the first part of Choice A above.

The second part is incorrect. Per NMP-OS-001 step 6.1.2.4, rod withdrawals are allowed if Tavg/Tref devation is within 3°F.

However, NMP-OS-001 step 6.1.2.4 states it is non-conservative to withdraw control rods in response to a transient and anomalies are to be mitigated utilizing the secondary plant. It is reasonable for a candidate not familiar with the specific guidance of NMP-OS-001 to believe that the Tavg/Tref of 2°F is still considered a "transient" and not allow the use of control rods. Therefore, this distractor is plausible.

C. Incorrect. Plausible. The first part is incorrect. Per the IPC printout, RCS DeltaT Power is approximately 83% and CBD position is 116 steps.

Per the COLR, the RIL for 83% power is 122 steps on CBD.

Therefore, ALB10-D04 is a valid alarm. However, if the candidate does not understand how RIL is calculated and uses NIS Power instead of DeltaT Power, an RIL of 105 steps would be determined and the candidate would conclude the alarm was Thursday, February 20, 2014 8:45:05 AM 2

not valid. Therefore, this distractor is plausible.

The second part is correct. See the second part of choice B above.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

The second part is correct. See the second part of choice B above.

Southern Nuclear Operating Company Nuclear NMP-OS-001 Management Reactivity Management Program Version 17.0 Procedure Page 10 of 39 6.1.2.3 Administrative Controls The following administrative requirements ensure that nuclear safety is maintained during activities that affect reactivity:

Planned reactivity manipulations are peer checked.

Calculations that involve reactivity control are independently verified prior to use.

Reactor operators use redundant instrumentation when monitoring the effects of reactivity manipulations.

Reactor engineering is actively engaged in activities that change reactivity significantly, including any special tests with the potential to affect reactivity.

The reactor operator performing rod movement activities is free from distractions and will have no other duties while performing reactivity manipulations.

See Attachment 2 for summarized expectations for reactivity manipulations.

6.1.2.4 Conduct of Reactivity Changes Operators anticipate the effects of reactivity manipulations and monitor core parameters carefully until parameters stabilize. Any unanticipated reactivity change is immediately brought to the attention of management and the resolution of the change is pursued to its conclusion.

Adding positive reactivity is never an appropriate way to address unstable plant conditions. It is non-conservative to withdraw control rods in response to primary plant anomalies caused by unplanned secondary plant transients. For the PWRs, once turbine load has been stabilized and RCS Tavg has been restored to within 3 degrees of Tref, positive reactivity can be added by withdrawing control rods.

Whenever the status of reactor criticality becomes unknown, the reactor is shutdown.

Under normal conditions, positive reactivity changes will not be performed by more than one means at a time.

During approach to criticality, two positive reactivity additions will not be performed simultaneously.

The operator at the controls shall suspend turnover if a reactivity manipulation is required during turnover.

- RCS pressure is 1350 psig and slowly lowering.

Which one of the following completes the following statement?

Stopping the RCPs is required to minimize the risk of __(1)__,

and per the Bases of Tech Spec 3.3.3, "Post Accident Monitoring (PAM) Instrumentation,"

for diverse indication of RCS Tcold temperature, the operator is directed to use __(2)__

instrumentation.

__(1)__ __(2)__

A. core uncovery RCS Thot B. core uncovery steam generator pressure C. RCP damage RCS Thot D. RCP damage steam generator pressure K/A 003 Reactor Coolant Pump G2.3.4 Ability to identify post-accident instrumentation.

K/A MATCH ANALYSIS The question tests the candidate's ability to identify the post-accident instrument that would be utilized as a diverse indication of RCS Tcold temperature with RCPs secured.

EXPLANATION OF REQUIRED KNOWLEDGE Per WOG Background for RCP Trip, the reason for purposely tripping the RCPs during a small break LOCA is to prevent excessive depletion of RCS water inventory through a saml break in the RCS which might lead to severe core uncovery if the RCPs were tripped for some reason later in the accident. The RCPs should be tripped before the RCS inventroy is depleted to the point where tripping of the pumps would cause the Thursday, February 20, 2014 1:26:28 PM 1

break to immediately uncover. The WOG gives options in parameter that may be utilzied as RCP trip criteria. Vogtle has chosen the option based solely on RCS pressure. Therefore, RCPs are manually tripped if RCS pressure is <1375 psig provided either CCPs or SIPs are injecting into the core.

Per TS 3.3.3 FU 2,3 Bases, steam line pressure provides diverse indication for the RCS cold leg temperature. With either forced or natural circulation flow through the steam generators, SGs will be at saturation pressure for the RCS Cold Legs.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 of the answer is correct and states the reason provided in the Westinghouse background documents for tripping the Reactor Coolant Pumps for small break LOCAs as the potential for core damage due to core uncover and exceeding peek centerline temperatures criteria.

Part 2 is not correct but is 'plausible' because T-hot instrumentation is addressed in the same bases as diverse indication for the CETCs as opposed to Tcold instrumentation.

The candidates would see there is a relationship since both are measuring temperature as opposed to the correct instrument which is using pressure.

B. Correct. Part 1 is correct. See Part 1 of choice A above.

Part 2 is correct. Per Tech Spec 3.3.3 'Post Accident Monitoring Instrumentation,' steam line pressure provides diverse indication for the RCS cold leg temperature.

C. Incorrect. Plausible. Part 1 is not correct for the small break LOCA but would be true for large break LOCAs since the Reactor Coolant Pumps would be stopped under this condition due to loss of support conditions for continued operation and subsequent pump damage.

Part 2 is not correct. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is not correct. See Part 1 of choice C above.

Part 2 of the answer is correct. See Part 2 of choice B above.

PAM Instrumentation B 3.3.3 BASES LCO 2,3. Reactor Coolant System (RCS) Hot and Cold Leg Temperatures (Wide Range) (continued)

RCS hot and cold leg temperatures are used to determine RCS subcooling margin. RCS subcooling margin will allow termination of safety injection (SI), if still in progress, or reinitiation of SI if it has been stopped. RCS subcooling margin is also used for unit stabilization and cooldown control.

In addition, RCS cold leg temperature is used in conjunction with RCS hot leg temperature to verify the unit conditions necessary to establish natural circulation in the RCS.

Reactor outlet temperature inputs to the Reactor Protection System are provided by two fast response resistance elements and associated transmitters in each loop. The channels provide indication over a range of 50qF to 700qF.

The core exit thermocouples provide diverse indication for the RCS hot leg temperature.

Steam line pressure provides diverse indication for the RCS cold leg temperature.

4. Steam Generator Water Level (Wide Range)

Wide range SG water level (Loops 501, 502, 503, & 504) is a Type A variable used to determine if an adequate heat sink is being maintained through the SGs for decay heat removal, primarily for the response to a loss of secondary heat sink event when the level is below the narrow range. The wide range SG level indication may also be used in conjunction with auxiliary feedwater flow for SI termination. In addition, the wide range level is cold calibrated and provides a complete range for monitoring SG level during a cooldown. Auxiliary feedwater flow provides the diverse indication for wide range SG water level.

1. 004G2.2.44 001/LOIT AND LOCT/SRO/C/A 4.2/4.4/004G2.2.44/LO-TA-16009///

Given the following procedure titles:

- 19000-C, "Reactor Trip or Safety Injection"

- 13003-1, "Reactor Coolant Pump Operation"

- 18005-C, "Partial Loss of Flow" Initial condition:

- Unit 1 is at 16% reactor power with a startup in progress.

Current conditions:

- ALB08-A04 RCP 1 NO. 2 SEAL LKOF HI FLOW is received.

- ALB08-A05 RCP 1 CONTROLLED LKG HI/LO FLOW is received.

- 1FI-160A, #1 SEAL LEAK-OFF for RCP #1 is indicating 6.0 gpm.

Which one of the following completes the following statement?

RCP #1, seal number __(1)__ has failed, and per 13003-1, the Shift Supervisor will direct the crew to __(2)__.

__(1)__ __(2)__

A. one initiate 18005-C B. one trip the reactor and initiate 19000-C C. two initiate 18005-C D. two trip the reactor and initiate 19000-C K/A 004 Chemical and Volume Control G2.2.44 Ability to interpret control room indications to verify the status and operation of a system, and understand how operator actions and directives affect plant and system conditions.

K/A MATCH ANALYSIS The question tests the candidates ability to interpret the control room annunciators associated with RCP seal #1 and #2 leak-offs. Seal injection and leakoff are part of the CVCS system per the K/A catalog. The candidate is then required to utilize these annunciators to diagnose the issue and select the appropriate procedure path to Tuesday, February 25, 2014 8:43:22 AM 1

address the degraded conditions.

EXPLANATION OF REQUIRED KNOWLEDGE Per ARP 17008-1 window A05, either low or high seal flow can actuate the alarm. High seal flow is an indication of Seal #1 failure, and low seal flow is an indication of Seal #2 failure. The candidate is given a seal flow of 6.0 gpm to allow differentiation between these two. Window A04 lists a probable cause of Seal #2 failure only. Knowledge of RCP seal package construction is required to understand why this annunciator would be consistent with a Seal #1 failure. As Seal #1 fails, the seal surfaces open and backpressure lowers within the package. Flow down the shaft lowers and increases both to the leak-off path and to Seal #2 .

Per 13003-1, Seal #1 leak-off >5.5 gpm requires stopping the RCP immediately per step 4.2.1.4. With reactor power greater than 15% RTP, the operator is directed to trip the reactor and initiate 19000-C. When the IOA's are complete, the operator is direct to perform steps 4.2.1.4.d thru h to stop the RCP, close the associated spray valve, and isolate seal #1 leak-off.

The question stem specifies 1FI-160A, #1 SEAL LEAK-OFF for RCP #1 is indicating 6.0 gpm. This is top of scale for the indicator. Simulations show that a seal failure equivalent to approximately 9 gpm leak leak-off is required for annunciators ALB08-A04 RCP 1 NO. 2 SEAL LKOF HI FLOW and ALB08-A05 RCP 1 CONTROLLED LKG HI/LO FLOW to be in alarm. At a seal leak-off of >4.8 gpm and <9 gpm, only annunciator ALB08-A05 RCP 1 CONTROLLED LKG HI/LO FLOW is in alarm.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is correct. The combination of annunciator alarms and elevated seal #1 leak-off are symptoms of a seal #1 failure.

The second part is incorrect. With seal #1 leak-off > 5.5 gpm, an immediate shutdown of the RCP is required. Per 13003-1 step 4.2.1.4, the reactor must be tripped and 19000-C initiated.

However, if a candidate does not realize RTP is >15%, then step 4.2.1.4 would direct initiation of AOP 18005-C.

B. Correct. The first part is correct. See the first part of choice A above.

The second part is correct. With seal #1 leak-off > 5.5 gpm, an immediate shutdown of the RCP is required. Per 13003-1 step 4.2.1.4, the reactor must be tripped and 19000-C initiated.

C. Incorrect. Plausible. The first part is incorrect. The combination of annunciator alarms and elevated seal #1 leak-off are symptoms of a seal #1 failure. However, if the candidate does not recognize 1FI-160A indicating 6.0 gpm as being abnormally high, then annunciator ALB08-A04 RCP 1 NO. 2 SEAL LKOF HI FLOW would be a symptom of a seal #2 failure.

The second part is incorrect. With seal #1 leak-off > 5.5 gpm, Tuesday, February 25, 2014 8:43:22 AM 2

an immediate shutdown of the RCP is required. Per 13003-1 step 4.2.1.4, the reactor must be tripped and 19000-C initiated.

However, if a candidate has diagnosed a seal #2 failure, 13003-C still supports an immediate stop of the RCP given other conditions. Since the question does not give an option to leave the RCP running, the candidate must assume a valid reason to stop the RCP has been met. As such, if the candidate then does not realize RTP is >15%, then step 4.2.1.4 would direct initiation of AOP 18005-C.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

The second part is correct. See the second part of choice B above.

(5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.

-Can the question be answered solely by knowing systems knowledge, i.e.,

how the system works, flowpath, logic, component location? No, the first part is system knowledge however, the second part is discriminating to the SRO level as it requires an operational decision.

-Can the question be answered solely by knowing immediate operator actions?

No, the requrired actions are specific direction associated with ARPs and SOPs and a shutdown decision must be made.

-Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, entry conditions to 18005-C and 19000-C both address plant conditions in a generic nature. Specific procedure knowledge is required to differentiate the required procedure flow path.

-Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, the question requires specific knowledge of a specific SOP step.

-Does the question require one or more of the following?

  • Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed. Yes, the candidate must use specific knowledge of SOP 13003-C decision flow charts from memory as well as specific knowledge of step 4.2.1.4 in order to direct the specific actions to be taken to shutdown the reactor and address the RCP seal failure.
  • Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps
  • Knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific subprocedures or emergency contingency procedures
  • Knowledge of administrative procedures that specify hierarchy, implementation, and/or coordination of plant normal, abnormal, and emergency procedures Tuesday, February 25, 2014 8:43:22 AM 3

2. Minimum startup requirements are 0.2 gpm at 200 PSID differential across the No. 1 seal. For startups at differential pressures greater than 200 PSID, the minimum No. 1 seal leak rate requirements are defined in the NO. 1 SEAL NORMAL OPERATING RANGE (e.g., at 1000 psi differential pressure, do not start the RCP with less than 0.5 gpm).
3. No.1 Seal Differential Press = RCS WR Press - VCT Press.
4. Per Westinghouse Technical Bulletin ESBU-TB-93-01-R1, total #1 seal leakoff is the sum of #1 seal leakoff and #2 seal leakoff. #1 seal leakoff is read directly at the MCB and #2 seal leakoff can be obtained from instrumentation in Containment.

Objective 4 Demonstrate using the seal package model.

The seal package consist of three seals

1) Number 1 seal (film riding) a) The primary seal b) Seal is accomplished with a hydrostatic film between the shaft runner and seal ring.

c) No mechanical contact between seal ring and shaft runner (must keep P >200 psid)

2) Number 2 seal (face rubbing) a) Provides back up for #1 seal b) Consist of carbon graphite (face rubbing seal) c) Graphite makes contact with runner which rotates with shaft d) If #1 seal fails , #2 seal converts to a film riding seal if #1 seal leak off valve is closed and seal is exposed to full RCS pressure. #2 seal designed to allow plant shutdown and should last approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

e) Placing #2 seal in service with the RCP shaft still rotating will tend to score the shaft at the #2 seal area. This can require extensive repairs before placing the RCP back in service. Vogtle chooses to remove RCP from service and allow its shaft to come to a standstill before closing the #1 seal leak off valve to avoid this problem.

3) Number 3 seal (face rubbing) a) Prevents the leakage of liquid and gases from the RCS into containment.

b) Consist of carbon graphite seal which makes contact with runner (face rubbing) c) The runner is around the shaft and rotates with it.

d) The seal is actually two graphite sealing surfaces called dams.

V-LO-PP-16401 12

Objective 1d

2) RCP Motor Auxiliaries A) Motor Cooler
1) Containment Air is drawn into the motor by fan blades on motors rotor
2) It is then exhausted through the motor cooler
3) ACCW is the cooling medium used in the cooler (cools the outgoing air)
4) This arrangement limits containment air temperature rise and in turn limits motor temperature.
3) Flywheel A) Addressed in tech spec administrative section B) Stores rotational energy of the pump and motor while running then releases energy by maintaining pump motion to slowly reduce core flow following loss of power for core protection.
4) RCP motor space heater A) Each RCP motor has a electric resistance heater.

B) Used to prevent moisture accumulation in windings when motor is shutdown.

C) Not needed when motor is in operation because of heat generation from motor windings.

D) Heaters are automatically energized when either of the RCP motor breakers are opened.

E) Heaters are supplied from 480 V MCCs RCP motor burned up at Vogtle that was attributed to moisture from space heater breaker being open when pump was shutdown. The space heater did not energize therefore moisture accumulated while the pump was shutdown during the outage. Upon restart the motor windings shorted out. Motor rebuild was required.

V-LO-PP-16401 13

Objective 2 RCP Seal Injection a) Provided from CVCS b) 8 gpm per pump c) 5 gpm is directed through to lower pump radial bearing and into the RCS loop.

d) The remaining 3 gpm supplies #1 and #2 seals e) #3 seal injection is from small tanks called Standpipes. (Gravity Fed) f) Flow path

1) 8 gpm from CVCS enters RCP at 2250 psig
2) 5 gpm passes through the lower pump bearing lubricating and cooling it.
3) Seal injection at 2250 psig prevents RCS water from escaping the loop.
4) 3 gpm is directed through #1 seal
5) A pressure drop at 2220 psid across the #1 seal occurs.
6) Approximately 3 gph (0.05 gpm) leak off from #1 seal is used as seal injection to #2 seal.
7) The remainder of #1 seal leak off is directed back to the VCT via seal water return.
8) 3 gph passes through #2 seal and the leak off is directed to the RCDT (~5-6 psig)
9) 800 cc/hr seal injection for #3 seal is provided by standpipe (~10 psig)
10) The standpipes are located at a higher elevation than the RCP and gravity feeds #3 seal; standpipes Auto fill from RMWST.
11) #3 seal injection is injected between the two dams and sealing surfaces.
12) #3 seal injection pressure is slightly higher than #2 seal injection leak off.
13) This prevents RCS liquids or gases from escaping to the containment environment.
14) #3 seal has two leak off paths a) The outer dam leak off (400 cc/hr) combines with #2 seal leak off and is routed to RCDT b) The inner dam leak off (400 cc/hr) is directed to the containment sump.

SMART - Solid Knowledge. If the #1 seal leakoff was isolated, the #2 seal would become a film riding seal due to increased pressure across the #2 seal facing.

Initial conditions:

- Unit 1 is at 100% reactor power.

- CCW pump #5 is tagged out for maintenance.

A2.02 Ability to (a) predict the impacts of the following malfunctions or operations on the CCWS and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations:

- High / Low surge tank level K/A MATCH ANALYSIS The candidate is presented with a plausible scenario where a CCW Surge Tank level Thursday, February 20, 2014 3:54:06 PM 1

transmitter fails low and is required to determine the impact of the failure on the system.

With one CCW pump tagged out and the inability to start the pump with the failed level transmitter, a decision of operability must be determined which is SRO required knowledge.

EXPLANATION OF REQUIRED KNOWLEDGE Each train of CCW is comprised of 3 pumps. Two pumps are required to met LCO 3.7.7. The pumps automatically start on SI, LOSP, Lo header pressure, and trip of a running pump. Only the SI and LOSP starts are required per SR 3.7.7.2.

When level switch 1-LSLL-1854 fails low, CCW pump #3 trips. With CCW pump #5 already tagged out, the system header pressure lowers and annunciators ALB02-A06 &

B06 alarm. Since automatic Demin Water Makeup Valve LV-1850 is controlled by level switches 1-LSL-1850 & 1-LSH-1850, its operation is not affected. (Reference P&ID 1X4DB136) No actual low level condition exists, therefore LV-1850 will not open.

Since 1-LSLL-1854 failing low resulted in a pump trip, SR 3.7.7.2 to verify each CCW pump starts automatically on an actual or simulated actuation signal can not be satsified. Per TS SR 3.0.1, failure to meet a Survelliance, whether such failure is experienced during the performance of the Survelliance or between performances of the Survelliance, shall be failure to meet the LCO. Therefore, CCW Pump #3 must be declared inoperable. Since CCW Pump #5 was already inoperable, TS 3.7.7 LCO is not met and RAS 'A' must be entered.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is incorrect. Since automatic makeup valve LV-1850 is controlled by level switches 1-LSL-1850 &

1-LSH-1850, its operation is not affected. No actual low level condition exists, therefore LV-1850 will not open. However, if the candidate believes makeup is controlled off the same level transmitter or misses that the level transmitter failed and believes there is an actual lo level, then makeup valve LV-1850 would be expected to open.

The second part is incorrect. SR 3.7.7.2 can not be met and CCW Pmp #3 and #5 are both inoperable. LCO 3.7.7 cannot be met. However, a candidate not familiar with the requirements of SR 3.7.72 & SR 3.0.1 or the pump start logic could conclude that the non-safety related surge tank low level trip would be bypassed on an SI or LOSP or that auto makeup would restore a low level condition and CCW Pmp #3 would remain OPERABLE.

B. Incorrect. Plausible. The first part is incorrect. See the first part of choice A above.

The second part is correct. SR 3.7.7.2 can not be met and CCW Pmp #3 and #5 are both inoperable. LCO 3.7.7 cannot be met.

Thursday, February 20, 2014 3:54:06 PM 2

C. Incorrect. Plausible. The first part is correct. Since automatic makeup valve LV-1850 is controlled by level switches 1-LSL-1850 &

1-LSH-1850, its operation is not affected. No actual low level condition exists, therefore LV-1850 will not open.

The second part is incorrect. See the second part of choice A above.

D. Correct. The first part is correct. See the first part of choice C above.

The second part is correct. See the second part of choice B above.

Per TS 3.4.13 Bases, identified leak is defined as being from a specifically known and located source, ie it must be collected and quantifiable, and not pressure boundary. Based on the given conditions, the leakrate is approximately 98 gpm, [charging-(letdown + seal leakoff)]. Total seal leakoff is normally about 12 gpm.

Since the leakage is across a vavle seat, it is not pressure boundary. Therefore, the leakage described fully meets the definition of IDENTIFIED.

Per NMP-EP-110-GL03 Figure 1, a potential loss of the RCS barrier exists if RCS leak rate is non-isolatabe and >120 gpm. Since leakrate is calculated to be 98 gpm, this threshold has not been exceeded. Per NMP-EP-110-GL02 Figure 2, NOUE threshold SU5 is exceeded if identified leakage is > than 25 gpm. Therefore, this threshold has been exceeded.

ANSWER / DISTRACTOR ANALYSIS A. Correct. Part 1 is correct it required the candidate to determine the type of RCS leakage based on information provided and knowledge of the Tech Spec definition of the various leakage categories.

From the information the candidate should determine this is identified leakage. LEAKAGE, such as that from pump seals or valve packing (except reactor coolant pump (RCP) seal water injection or leakoff), that is captured and conducted to collection systems or a sump or collecting tank.

Part 2 required the candidate to take the information gathered in Part 1 and apply it to the various Emergency Action Level classification thresholds. From that a leak rate of 98 gpm is determined and limits for NOUE recognized as exceeded.

B. Incorrect. Plausible. Part 1 is correct. See Part 1 of choice A above.

Part 2 is incorrect but plausible because the candidate may determine that 110 gpm charging added to 32 gpm seal injection (which is alreay included in the charging flow indicator reading) going into RCS is 142 GPM leak. This minus the RCP seal return flow of 3.2 each gpm would be above the ALERT threshold of 120 gpm for the potential loss of the RCS barrier. (Reference P&IDs 1X4DB114 and 1X4DB116-1)

C. Incorrect. Plausible. Part 1 is incorrect but 'plausible' in that the candidate must first identify the type of RCS leakage. As the PRT continues to recieve effluent from the Przr Code Safety, it will eventually Friday, February 21, 2014 10:13:47 AM 2

rupture. If the candidate assumes that once this occur the leakage is no longer being "collected" in the PRT and not think about the leakage now being colleted in the containment sump, then it would be reasonable to interpret the indications as UNIDENTIFIED RCS leakage.

Part 2 is correct. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is incorrect. See Part 2 of choice B above.

RCS Operational LEAKAGE B 3.4.13 BASES (continued)

APPLICABLE Except for primary to secondary LEAKAGE, the safety analyses SAFETY ANALYSES do not address operational LEAKAGE. However, other operational LEAKAGE is related to the safety analyses for LOCA; the amount of leakage can affect the probability of such an event. The safety analyses for an event resulting in steam discharge to the atmosphere assumes that primary to secondary LEAKAGE from all steam generators (SGs) is one gallon per minute or increases to one gallon per minute as a result of accident induced conditions. The LCO requirement to limit primary to secondary LEAKAGE through any one SG to less than or equal to 150 gallons per day is significantly less than the conditions assumed in the safety analysis.

The RCS operational LEAKAGE satisfies Criterion 2 of 10 CFR 50.36 (c)(2)(ii).

LCO RCS operational LEAKAGE shall be limited to:

a. Pressure Boundary LEAKAGE No pressure boundary LEAKAGE is allowed, being indicative of an off-normal condition. LEAKAGE of this type is unacceptable as the leak itself could cause further deterioration, resulting in higher LEAKAGE. Violation of this LCO could result in continued degradation of the RCPB. LEAKAGE past seals and gaskets is not pressure boundary LEAKAGE.
b. Unidentified LEAKAGE One gallon per minute (gpm) of unidentified LEAKAGE is allowed as a reasonable minimum detectable amount that the containment air monitoring and containment sump level monitoring equipment can detect within a reasonable time period. Violation of this LCO could result in continued degradation of the RCPB, if the LEAKAGE is from the pressure boundary.
c. Identified LEAKAGE Up to 10 gpm of identified LEAKAGE is considered allowable because LEAKAGE is from known sources that do not interfere with detection of unidentified LEAKAGE and is well within the capability of the RCS Makeup System. Identified LEAKAGE includes LEAKAGE to the containment from specifically known and located sources, but does not include pressure boundary (continued)

Vogtle Units 1 and 2 B 3.4.13-2 Rev. 2-9/06

RCS Operational LEAKAGE B 3.4.13 BASES LCO c. Identified LEAKAGE (continued)

LEAKAGE or controlled reactor coolant pump (RCP) seal leakoff (a normal function not considered LEAKAGE). Violation of this LCO could result in continued degradation of a component or system.

d. Primary to Secondary LEAKAGE through Any One SG The limit of 150 gallons per day per SG is based on the operational LEAKAGE performance criterion in NEI 97-06, Steam Generator Program Guidelines (Ref. 4). The Steam Generator Program operational LEAKAGE performance criterion in NEI 97-06 states, The RCS operational primary to secondary leakage through any one SG shall be limited to 150 gallons per day. The limit is based on operating experience with SG tube degradation mechanisms that result in tube leakage. The operational leakage rate criterion in conjunction with the implementation of the Steam Generator Program is an effective measure for minimizing the frequency of steam generator tube ruptures.

APPLICABILITY In MODES 1, 2, 3, and 4, the potential for RCPB LEAKAGE is greatest when the RCS is pressurized.

In MODES 5 and 6, LEAKAGE limits are not required because the reactor coolant pressure is far lower, resulting in lower stresses and reduced potentials for LEAKAGE.

LCO 3.4.14, "RCS Pressure Isolation Valve (PIV) Leakage,"

measures leakage through each individual PIV and can impact this LCO. Of the two PIVs in series in each isolated line, leakage measured through one PIV does not result in RCS LEAKAGE when the other is leak tight. If both valves leak and result in a loss of mass from the RCS, the loss must be included in the allowable identified LEAKAGE.

The 10 gpm value for the unidentified and pressure boundary leakage was selected as it is observable with normal control room indications. Lesser values must generally be determined through time-consuming surveillance tests (e.g., mass balances). The Threshold Value for identified leakage is set at a higher value due to the lesser significance of identified leakage in comparison to unidentified or pressure boundary leakage.

K/A MATCH ANALYSIS Friday, February 21, 2014 11:25:14 AM 1

The question sets up plausible scenario where the candidate must first determine which instruments are required to be referenced when complying with the Containment temperature monitoring verification surveillance of Technical Specifications. A decision is required based on the operating limit in comparison with an IPC screen shot. The second part matches the KA for the Shift Supervisor to evaluate Containment Cooling requirements used to control within environmental limits and the first part makes this SRO required knowledge when the surveillance requirement is tested.

EXPLANATION OF REQUIRED KNOWLEDGE Per TS SR 3.6.5.1, containment average temperature is required to be verified <120F on a periodic bases. The IPC screen for Control Room TS Rounds lists values for CMNT Levels 2, C, & B and an average temperature. Individual readings above 120F are acceptable as long as the average temperature is <120F.

Per OSP 14000-1, page 15, if the IPC points for containment temperature are not available, annunciator ALB01-E06 can be verified extinquished as an alternate. This annunciator utilzes temperature elements from all three levels and has a setpoint of

<120F. If the annunciator is in alarm and the IPC is unavailable, then local temperature readings are required.

Per ARP 17001-1 for ALB01-E06, if any of the three containment temperature indicators rise above 120F, the operator is instructed to start an additional pair of Containment Coolers. Containment Coolers must be started in specific pairs (1&2, 3&4, 5&6, and 7&8) due to the backdrafter damper for the individual fans being de-energized open on a common plentum (reference P&ID 1X4DB212 and SOP 13120-1 section 4.1). Starting the fans one at a time will result in the non-running fan of the pair to spinning backwards. When the second fan is subsequently started, the supply breaker will trip open from high in-rush current produced by the increased electrical slip angle.

Since fan #1 tripped, fan #2 should be stopped prior to starting an additional pair. Fan

  1. 2 is mostly recirculating short-cycled flow in the current configuration and is producing little cooling to containment. Simply starting a second fan on another pair would only create the same condition on a second pair and would also do little to lower containment temperature.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is correct and sets up a circumstance were the candidate must determine which instrumentation in particular is required to be monitored the ensure compliance with SR 3.6.5.1 for Containment temperature. The SR requires the average temperature of three levels in Containment be noted to ensure Containment temperature remains within the accident analyses.

Part 2 is incorrect but 'plausible' because the candidate may determine that the only required action is to start an additional Containment Cooler to replace the tripped Containment cooler not recalling that the system operating procedure would require Friday, February 21, 2014 11:25:14 AM 2

the fans be operated in pairs.

B. Correct. Part 1 is correct. See Part 1 of choice A above.

Part 2 is correct per the ARP 17001-1, and the SOP 13120-1, an additional pair of Containment Coolers would be started.

C. Incorrect. Plausible. Part 1 is incorrect but 'plausible' in that the candidate may determine that Technical Specification if any of the three levels listed on the IPC printout exceeded 120F. This assumption would be consistent with the use of ALB01-E06 as an alternate as described in OSP 14000-1.

Part 2 is incorrect. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is correct. See part 2 of choice B above.

Which one of the following completes the following statement?

At time 1115, the Shift Manager must declare a(n) __(1)__ per NMP-EP-110, "Emergency Classification Determination and Initial Action,"

and no later than time 1130, as a minimum, the __(2)__ must be notified of the declaration per NMP-EP-111, "Emergency Notifications."

REFERENCE PROVIDED

__(1)__ __(2)__

A. NOUE NRC, state, and local authorities B. NOUE state and local authorities C. Alert NRC, state, and local authorities D. Alert state and local authorities K/A 025 Loss of RHR System G2.4.30 Knowledge of events related to system operation/status that must be reported to internal organizations or external agencies, such as the State, the NRC, or the transmission system operator.

K/A MATCH ANALYSIS The question sets up a plausible scenario which includes the first required element of Friday, February 21, 2014 12:40:33 PM 1

the KA loss of RHR cooling, then has the candidate evaluate plant conditions and make determination of reporting requirements which meets the second part of the KA and brings the knowledge to the SRO required level.

EXPLANATION OF REQUIRED KNOWLEDGE Based on the conditions in the stem, 2 EPIPs classification thresholds have been exceed. First, an LOSP has existed with only the 'B' DG energizing 1BA03. As such NOUE CU3 has been exceeded. Additonally, due to both RHR pumps not running, RCS temperature has risen above 200F while in Mode 4. Containment integrity is not established. Since all pressurizer safeties are removed, RCS integrity is also not established. As shuch, ALERT CA4 has also been exceeded. Therefore, the Emergency Director is required to declare an ALERT emergency on or before 11:15 per NMP-EP-110.

Per NMP-EP-111 steps 5.1.1 ad 5.1.3, state and local agencies must be notified within 15 minutes of the declaration, which would be 11:30. Additionally, the NRC shall be notified immediately follwoing the state and local agencies and within an hour of the declaration.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is incorrect but plausible because the candidate may determine the loss of power event is driving the initial classification not recognizing the loss of RHR Cooling and CU3 would be the correct.

Part 2 is incorrect but plausible because the candidate may determine that the NRC must be notified in this condition within 15 minutes. Per NMP-EP-111, Notification of the NRC shall be completed immediately following notifications to the state and local agencies and within an hour of the declaration of an emergency. Therefore, the NRC is not REQUIRED to be notified by 11:30, but instead is allowed additonal time if needed up to an hour, but is to be done as soon as possible following the state and locals.

B. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice A above.

Part 2 is correct in that within 15 minutes of the classification of the NOUE the state and local authorities must be notified per NMP-EP-111, "Emergency Notifications". Notifications of applicable State and Local Agencies shall be accomplished as soon as practicable and within 15 minutes of the declaration of an emergency, an upgrade to a higher emergency classification level, or the approval of protective actions recommendations.

C. Incorrect. Plausible. Part 1 is correct and has the candidate evaluate plant conditions and determine the event meets the ALERT threshold for CA4 due to being in Mode 5 with RCS temperature >200F without containment and RCS integrity established.

Friday, February 21, 2014 12:40:33 PM 2

without containment and RCS integrity established.

Part 2 is incorrect. See Part 2 of choice A above.

D. Correct. Part 1 is correct. See Part 1 of choice C above.

Part 2 is correct. See Part 2 of choice B above.

SRO JUSTIFICATION (5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.

-Can the question be answered solely by knowing systems knowledge, i.e.,

how the system works, flowpath, logic, component location? No, the answer requires specific knowledge of emergency classification thresholds.

-Can the question be answered solely by knowing immediate operator actions?

No, IOAs are not addressed by this question.

-Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, the question does not address AOP or EOP entry conditions.

-Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, the answer requires specific knowledge of emergency classification thresholds.

-Does the question require one or more of the following?

  • Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed
  • Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps
  • Knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific subprocedures or emergency contingency procedures
  • Knowledge of administrative procedures that specify hierarchy, implementation, and/or coordination of plant normal, abnormal, and emergency procedures. Yes, the answer requires specific knowledge of emergency classification thresholds and determination of the specific classification based on current plant conditions. This is an SRO ONLY job link associated with an SRO ONLY objective. [LO-LP-40101-13 Given an emergency scenario, and the procedure, classify the emergency (SRO only).]

Southern Nuclear Operating Company Emergency NMP-EP-111 Implementing Emergency Notifications Version 8.0 Procedure Page 7 of 12 4.3.3 The ENS functions DO NOT normally transfer to the EOF. The EOF has an ENS communicator position that coordinates with the TSC ENS communicator to maintain a continuous open communication line with the NRC. The role of the EOF ENS Communicator is to assist in communications with the NRCOC relevant to activities performed from the EOF (i.e., offsite interface, public information, PAR development, Dose assessment activities, etc.).

5.0 PROCEDURE 5.1 Precautions and Limitations 5.1.1 Notifications of applicable State and Local Agencies shall be accomplished as soon as practicable and within 15 minutes of the declaration of an emergency, an upgrade to a higher emergency classification level, or the approval of protective actions recommendations.

5.1.2 Electronic notification using the electronic Emergency Notification Form (ENF) in WebEOC is the preferred method of notification of State and Local Agencies. Should WebEOC be unavailable the back-up notification method is completion of a hard copy ENF and reading the form to the applicable State and Local Agencies via the ENN. Whether using the electronic or back-up ENF the emergency notification to an agency is considered complete when the agency verbally confirms receipt of the message via the ENN. To expedite availability of WebEOC in an emergency, the crew members responsible for completing the ENF and making electronic notifications should login to WebEOC as soon as possible and remain logged-in.

5.1.3 Notification of the NRC shall be completed immediately following notifications to the state and county agencies and within an hour of the declaration of an emergency. Follow-up notifications of the NRC shall be made promptly after any further degradation in the plant conditions, any change from one emergency class to another, or for the termination of an emergency. NRC notifications are typically performed utilizing the Federal Telephone System (FTS). The Emergency Notification System (ENS) line is normally utilized. An open line is maintained for the duration of the event at the request of the NRC communicator receiving the initial notification.

5.1.4 For security based emergencies, notifications to the NRC should be performed within 15 minutes of discovery of an imminent threat or attack against the plant to ensure proper mobilization of federal resources.

CAUTION An initial notification of an upgrade in emergency Classification should take precedence over a follow-up message of a lower ranking emergency. (i.e., an initial site area emergency notification takes precedence over an alert follow-up notification.)

5.1.5 If the plant condition degrades and a higher emergency classification is declared before the notifications are confirmed for the lesser emergency declaration, then a notification reflecting the higher emergency classification should be made. This notification should be made within 15 minutes of the lesser emergency declaration. This should be performed IF the notification can be made within 15 minutes of the lesser (first) classification.

Which one of the following completes the following statement?

To prevent damage to the RCP, the RCP must be stopped no later than time __(1)__,

and after the reactor is tripped, the Shift Supervisor directs the OATC to stop the affected RCP per __(2)__ direction.

- The length of time after the loss of CCW flow to a component Friday, February 21, 2014 1:21:51 PM 1

before that component may be damaged.

K/A MATCH ANALYSIS To answer this question, the applicant must know that loss of ACCW will lead to entry into 19000-C, requiring a manual trip (even though it does not approach or exceed any automatic setpoints), and which procedure provides the action. Since the Shift Supervisor is required to recall the specific strategy from the 18022-C procedure, the choices involve SRO only knowledge of the procedure flow path of the AOP (past the entry conditions and there are no immediate actions in 18022-C), and knowledge of the need to enter 19000-C. In addition, the question requires the candidate to recall not only how long the RCPs can operate without ACCW cooling but to evaluate other parameters that may require immediate stopping of the pumps.

EXPLANATION OF REQUIRED KNOWLEDGE At 1005, annunciators ALB04-A03 and A04 indicate a complete loss of ACCW flow to RCP #1 only. AOP 18022-C is entered. Step 6 checks to see if the RCP should be stopped. At 1016, RCP #1 would have sustained a total loss of ACCW for >10 minutes and must be stopped. The stem also states that seal water inlet temperature is rising at a rate of 1F/min. At 1018, the RCP must be stopped due to seal water inlet temperature. Additionally, motor stator winding temperature is also rising at a rate f 1F/min. At 1012, 311F would have been exceeded and the RCP must be stopped.

Therefore, the most limiting operationg condition would be the stator winding temperature and the the RCP must be stopped no later than 1012. The RCP operationg parameters in 18022-C are the same as those listed in SOP 13003-1 Limitation 2.2.10.

Since the reactor is greater than 15% RTP, the reactor must be tripped prior to tripping the RCP. Tripping the reactor is a direct entry condition into EOP 19000-C. On step 11 of 19000-C, a check of ACCW status is made and the RNO directs stopping the RCP.

However, 18022 step 6 is specifically design to trip the reactor and stop the RCP prior to performing EOP 19000-C. This is done to ensure the RCP is not damaged in the time required to perform the initial steps of 19000-C before direction to stop the RCP is encountered.

ANSWER / DISTRACTOR ANALYSIS A. Correct. Part 1 is correct. Based of Westinghouse vendor requirements the RCPs must be stopped under normal conditions when ACCW cooling is lost to the motors to prevent potential damage. This is supported by SOP 13003-1, which establishes the ACCW operating time limit of 10 minutes and other trip parameters. In the case presented to the candidate the most limiting parameter is the stator limit of 311F which will require the pump to be stopped within 5 minutes of 10:07 (i.e. 10:12).

Part 2 is correct because 18022-C directs manual reactor trip, verify trip, the stop RCPs then perform 19000-C, therefore the correct direction to stop the RCP is 18022-C as opposed to 19000-C.

Friday, February 21, 2014 1:21:51 PM 2

B. Incorrect. Plausible. Part 1 is correct. See Part 1 of choice A above.

Part 2 is incorrect but plausible because the candidate may determine that the direction that is provided in 19000-C step 11 would be used to stop the RCPs as opposed to 18022-C step 1.

The 10 minute time allowance could lead the candidate to determine there is no real pressure to speed up the action to stop the RCPs, prior to the initial steps in 19000-C.

C. Incorrect. Plausible. Part 1 is incorrect however is plausible since the candidate may determine that none of the operating limits provided in the stem is above limits or will reach their limit within 10 minutes, therefore the 10 minutes becomes the most limiting factor.

Part 2 is correct. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is correct. See Part 2 of choice B above.

SRO JUSTIFICATION (5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.

-Can the question be answered solely by knowing systems knowledge, i.e.,

how the system works, flowpath, logic, component location? No, the system parameter needed to determine if the RCP should be stopped is system level knowledge. However, the direction to stop the RCP requires specific knowledge and priortization of steps in both the AOP and EOP.

-Can the question be answered solely by knowing immediate operator actions?

No, there are no IOAs associated with the actions addressed in this question.

-Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, stopping an RCP has nothing to do with the entry conditions for either AOP 18022-C or EOP 19000-C. 19000-C does have entry conditions associated with trip of the reactor, which would stem from stopping an RCP at 100% RTP. However, this would lead a candidate down the incorrect path.

-Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, specific knowledge of individual procedure steps is required.

-Does the question require one or more of the following?

  • Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed
  • Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps
  • Knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific subprocedures or emergency Friday, February 21, 2014 1:21:51 PM 3

Initial condition:

- Unit 1 reactor trip and SI occurred.

Current conditions:

- 19011-C, "SI Termination," Step 21, is in progress to evaluate if a bubble exists in the pressurizer.

- Controlling pressurizer level channel, 1LT-459, fails low.

- Actual pressurizer level is 92% and slowly rising.

Which one of the following completes the following statement?

Per 10020-C, "EOP and AOP Rules of Usage," the Shift Supervisor __(1)__ direct the use of 18001-C, "Systems Instrumentation Malfunction," guidance to restore pressurizer heaters to service while performing 19011-C actions, and in response to actual pressurizer level, the Shift Supervisor __(2)__ required to transition to 19261-C, "Response to High Pressurizer Level."

__(1)__ __(2)__

A. may is NOT B. may is C. may NOT is NOT D. may NOT is K/A 028 Pressurizer Level Malfunction G2.4.8 Knowledge of how abnormal operating procedures are used in conjunction with EOPs.

K/A MATCH ANALYSIS The question is requires the candidate to determine if AOP 18001-C can be used in conjunction with EOP 19011-C to mitigate complications arising from a failed pressurizer level instrument. The question is elevated to the SRO level by requiring the candidate to make decision on whether to direct implementation of procedures during EOP implementation.

Friday, February 21, 2014 3:33:47 PM 1

EXPLANATION OF REQUIRED KNOWLEDGE Per EOP and AOP rules of usage 10020-C step 3.5.9, other procedures such as AOPs and ARPs may be performed in parallel with EOPs as long as their actions do not conflict with the EOP steps. EOP actions take priority. In both steps 21 and 26 of EOP 19011-C, pressurizer heaters are required to be energized to saturate the pressurizer.

With pressurizer level at 92% and rising, this becomes a crucial action, however the step cannot be accomplished due to heaters being tripped off as a result of LT-459 failing low. The use of 18001-C to select away from the failed channel and restore pressurizer heaters is a prudent and necessary action.

With pressurizer level at 92% and rising, a yellow path on the CSFST for INVENTORY should exist. Per 19200-C step 1 RNO, if a yellow path exist, then initiate FRP based on plant conditions with Shift Supervisor approval. Per step 11 RNO, transition to FRP 19261-C should only be made if solid plant condtions exist, which are not currently present. Therefore, 19261-C is not required to be entered and should not be entered at this time. Instead, the priority should be placed on restoring pressurizer heaters and continuing efforts to lower pressurizer level via charging/letdown mismatch.

ANSWER / DISTRACTOR ANALYSIS A. Correct. Part 1 is correct. Per 10020-C 'EOP and AOP Rules of Usage', Other procedures such as AOPs or ARPs may be performed in parallel with EOPs as long as their actions do not conflict with the EOP steps. EOP actions take priority.

Additionally, performance of 18001-C to restore pressurizer heaters is prudent and necessary.

Part 2 is correct. 19200-C 'Critical Safety Function Status Trees', states IF a Yellow condition exists, THEN initiate FRP after evaluating plant conditions with Shift Supervisor's approval. 19011-C "SI Termination' states IF solid plant conditions are present, THEN refer to 19261 C, FR I.1 Response to High Pressurizer Level. Solid plant conditions are not present. Entry into 19261-C would actually impede the success path in 19011-C.

B. Incorrect. Plausible. Part 1 is correct. See Part 1 of choice A above.

Part 2 is incorrect but 'plausible' because the candidates know that EOP actions always take priority. The candidate may not realize 19261-C does not contain any steps that would be different from those already in progress in 19011-C and believe transition to 19261-C is necessary to prevent going solid in the pressurizer.

C. Incorrect. Plausible. Part 1 is incorrect but plausable because 10020-C 'EOP and AOP Rules of Usage', Other procedures such as AOPs or ARPs may be performed in parallel with EOPs as long as their actions do not conflict with the EOP steps. EOP actions take priority.

Friday, February 21, 2014 3:33:47 PM 2

The candidate may not realize that the sucess path for current plant conditions resides in restoring pressuirzer heaters and deems use of 18001-C as unnecessarily slowing the progress of the EOP 19011-C.

Part 2 is correct. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is incorrect. See Part 2 of choice B above.

(Note: At Vogtle, Source Range NIs high voltage power supplies are no longer automatically removed - GAMAMETRICS now installed.)

EXPLANATION OF REQUIRED KNOWLEDGE Wednesday, February 26, 2014 8:20:39 AM 1

The candidate is required to know TS 3.9.3 Bases to determine the Operability of the Source Range NIs. In Mode 6, one SR NI can be powered from a Non-1E power supply provided the other SR NI is powered from it's normal 1E power supply.

Additionally, the candidate is required to determine the SR NI indication following a loss of the high voltage power supply. In this situation, the NI detector would be down powered and the indication would drop to bottom of scale.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is correct. When any of the safety-related busses supplying power to one of the detectors (NI-0031 or NI-0032) associated with the source range neutron flux monitors are taken out of service, the corresponding source range neutron flux monitor may be considered OPERABLE when its detector is powered from a temporary nonsafety-related power source, provided the detector for the opposite source range neutron flux monitor is powered from its normal source.

The second part is incorrect. Loss of the high voltage power supply will constitute a complete loss of power to the SR NI detectors, resulting in indication failing to bottom of scale.

However, the NI's have 3 different power supplies that support various functions. If a loss of control power only occurs, all bistables trip, however NI indication is unchanged and remains "as-is". Therefore, this distractor is plausible.

B. Correct. The first part is correct. See the first part of choice A above.

The second part is correct. The loss of the High Voltage Power Supply will result in a complete loss of power to the SR NIs and indication will read bottom of scale.

C. Incorrect. Plausible. The first part is incorrect. Per TS 3.9.3 Bases, one SR NI can be powered from a Non-1E power supply provided the other SR NI is powered from it's normal 1E power supply in Mode 6. It is abnormal for a Safety-Related, Tech Spec required component to be powered from a non-1E power supply and be considered OPERABLE. It is reasonable for a candidate without knowledge of this specific exception to determine the LCO not met. Therefore, this distractor is plausible.

The second part is incorrect. See the second part of choice A above.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

The second part is correct. See the second part of choice B above.

Nuclear Instrumentation B 3.9.3 B 3.9 REFUELING OPERATIONS B 3.9.3 Nuclear Instrumentation BASES BACKGROUND The source range neutron flux monitors are used during refueling operations to monitor the core reactivity condition. The installed source range neutron flux monitors (NI-0031 and NI-0032) are part of the Nuclear Instrumentation System (NIS). These detectors are located external to the reactor vessel and detect neutrons leaking from the core. Temporary neutron flux detectors which provide equivalent indication may be utilized in place of installed instrumentation.

The installed source range neutron flux monitors are fission chamber detectors. The detectors monitor the neutron flux in counts per second. The instrument range covers seven decades of neutron flux (1E-1 cps to 1E +6 cps) with a 2% instrument accuracy. The detectors also provide continuous visual indication in the control room.

The NIS is designed in accordance with the criteria presented in Reference 1.

APPLICABLE Two OPERABLE source range neutron flux monitors are required SAFETY ANALYSES to provide a signal to alert the operator to unexpected changes in core reactivity such as an improperly loaded fuel assembly. The need for a safety analysis for an uncontrolled boron dilution accident is minimized by isolating all unborated water sources except as provided for by LCO 3.9.2, "Unborated Water Source Isolation Valves."

The source range neutron flux monitors satisfy Criterion 3 of 10 CFR 50.36 (c)(2)(ii).

LCO This LCO requires that two source range neutron flux monitors be OPERABLE to ensure that redundant monitoring capability is available to detect changes in core reactivity. To be OPERABLE each monitor must provide visual indication.

When any of the safety-related busses supplying power to one of the detectors (NI-0031 or NI-0032) associated with the source range neutron flux monitors are taken out of service, the corresponding source range neutron flux monitor may be considered OPERABLE when its detector is powered from a temporary nonsafety-related (continued)

Nuclear Instrumentation B 3.9.3 BASES LCO source of power, provided the detector for the opposite source range (continued) neutron flux monitor is powered from its normal source.

APPLICABILITY In MODE 6, the source range neutron flux monitors must be OPERABLE to determine changes in core reactivity. There are no other direct means available to check core reactivity levels. In MODES 2, 3, 4, and 5, the operability requirements for the installed source range detectors and circuitry are specified in LCO 3.3.1, "Reactor Trip System (RTS) Instrumentation."

ACTIONS A.1 and A.2 With only one source range neutron flux monitor OPERABLE, redundancy has been lost. Since these instruments are the only direct means of monitoring core reactivity conditions, CORE ALTERATIONS and positive reactivity additions must be suspended immediately. Performance of Required Action A.1 shall not preclude completion of movement of a component to a safe position or normal cooldown of the coolant volume for the purpose of system temperature control.

B.1 Condition B is modified by a Note to clarify the requirement that entry into or continued operation in accordance with Condition A is required for any entry into Condition B. The Note reinforces conventions of LCO applicability as stated in LCO 3.0.2 and as reflected in examples in 1.3, Completion Times.

With no source range neutron flux monitor OPERABLE, action to restore a monitor to OPERABLE status shall be initiated immediately.

Once initiated, actions shall be continued until a source range neutron flux monitor is restored to OPERABLE status.

B.2 With no source range neutron flux monitor OPERABLE, there are no direct means of detecting changes in core reactivity. However, since CORE ALTERATIONS and positive reactivity additions are not to be (continued)

Procedure 13719-1, "Spent Fuel Pool Cooling and Purification," sections as follows:

- Section 4.2.2, "SFP Makeup from the RWST through the SFP Purification Loop"

- Section 4.2.4, "SFP Makeup from the RMWST" Initial conditions:

- Unit 1 is defueled.

- Transfer canal is drained for transfer cart inspection.

- Spent fuel shuffle is in progress in the FHB.

Current conditions:

- ALB05-E02 SPENT FUEL PIT LO LEVEL is received.

- Personnel in the FHB report SFP level is slowly lowering.

- 18030-C, "Loss of Spent Fuel Pool Level or Cooling," is entered.

Which one of the following completes the following statement?

To mitigate the consequences of the event, the Shift Supervisor is required to direct makeup to the SFP using 13719-1, Section __(1)__,

and per the Bases of Tech Spec 3.7.15, "Fuel Storage Pool Water Level," maintaining the required minimum water level in the SFP __(2)__ ensure adequate iodine decontamination factors are met for a fuel handling accident.

K/A MATCH ANALYSIS The question tests the candidate's ability to predict the impact of low spent fuel pool level by having to recall the bases for TS 3.7.15 level. The candidate is also required to mitigate the consequence of the event through the selection of a makeup source by selecting the appropriate procedure section to perform.

EXPLANATION OF REQUIRED KNOWLEDGE Per ARP 17005-1, ALB05-E02 alarms at a Spent Fuel Pool Level of 217'-0". Reports from the field have verified and low and decreasing pool level. AOP 18030-C is entered to mitigate the event. Per step 6 of this procedure, makeup to the SFP per SOP 13719-1 is directed. The specific procedure section is not specified. The candidate must recognize that makeup due to leakage will be from the RWST and not the RMWST. This ensures SFP boron concentration will be maintained. This requirement is stipulated in SOP 13719-1 Precaution and Limitation 2.1.7 and in a CAUTION at the beginning of sections 4.2.3 and 4.2.4. These state that non-borated makeup is usually only allowed for normal evaporative level losses. Borated water sources are the preferred maekup source for abnormal or unexplained level losses. Objective LO-PP-25102-11 is utilized during LOIT to re-enforce the use of borated water sources only during leakage.

With SFP level less than the Tech Spec limit of 217'-0", less than 23 feet of water exist over the spent fuel stored in the racks. Per TS 3.7.15 Bases, the minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident. The bases also discusses TS 3.7.15 water level as providing shielding to minimize general area dose and provide shielding during spent fuel movement.

ANSWER / DISTRACTOR ANALYSIS A. Correct. The first part is correct. Per SOP 13719-1 Spent Fuel Pool Cooling and Purification System, makeup due to leakage is from a borated source.

The second part is correct. Per Technical Specification 3.7.15 Fuel Storage Pool Water Level bases, the minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident.

B. Incorrect. Plausible. The first part is correct. See the first part of choice A above.

The second part is incorrect. Per Technical Specification 3.7.15 Fuel Storage Pool Water Level bases, the minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident.

However, the bases also discusses the shielding function of the water, which is a more commonly known benefit. A candidate without adequate knowledge of the TS Bases, may conclude that iodine decontamination is not a factor at all for water level, Friday, February 21, 2014 3:41:24 PM 2

or may assume the normal minimum water level of 218'-0" required. Therefore, this distractor is plausible.

C. Incorrect. Plausible. The first part is incorrect. Per SOP 13719-1 Spent Fuel Pool Cooling and Purification System, makeup due to leakage is from a borated source. However, normally SFP makeup is made from either Demin Water or the RMWST since the level change is due to evaporative loss and the boron is left in solution. A candidate with inadequate knowledge of the purpose behind using the different sources would find it reasonable to makeup using a normal source. Therefore, this distractor is plausible.

The second part is correct. See the second part of choice A above.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

The second part is incorrect. See the second part of choice B above.

-Need to make sure Section 4.2.4 cannot be argued as a correct answer. 13719 and EOP caution say borated water "should" rather than "shall" be used.

-Having Keff requirements as a basis for the SFP water level does not seem plausible. However, I think this can be solved by reframing the second question to state "per Bases of Tech Spec 3.7.15", maintain the required minimum water level in the SFP does/does not ensure adequate idodine decontamination factors are met.

Fuel Storage Pool Water Level B 3.7.15 B 3.7 PLANT SYSTEMS B 3.7.15 Fuel Storage Pool Water Level BASES BACKGROUND The minimum water level in the fuel storage pool meets the assumptions of iodine decontamination factors following a fuel handling accident. The specified water level shields and minimizes the general area dose when the storage racks are filled to their maximum capacity. The water also provides shielding during the movement of spent fuel.

A general description of the fuel storage pool design is given in the FSAR, Subsection 9.1.2 (Ref. 1). A description of the Spent Fuel Pool Cooling and Cleanup System is given in the FSAR, Subsection 9.1.3 (Ref. 2). The assumptions of the fuel handling accident are given in the FSAR, Subsection 15.7.4 (Ref. 3).

APPLICABLE The minimum water level in the fuel storage pool meets SAFETY ANALYSES the assumptions of the fuel handling accident described in Regulatory Guide 1.25 (Ref. 4). The resultant 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> thyroid dose per person at the exclusion area boundary is a small fraction of the 10 CFR 100 (Ref. 5) limits.

According to Reference 4, there is 23 ft of water between the top of the damaged fuel bundle and the fuel pool surface during a fuel handling accident. With 23 ft of water, the assumptions of Reference 4 can be used directly. In practice, this LCO preserves this assumption for the bulk of the fuel in the storage racks. In the case of a single bundle dropped and lying horizontally on top of the spent fuel racks, however, there may be < 23 ft of water above the top of the fuel bundle and the surface, indicated by the width of the bundle. To offset this small nonconservatism, the analysis assumes that all fuel rods fail, although analysis shows that only the first few rows fail from a hypothetical maximum drop.

The fuel storage pool water level satisfies Criterion 2 of 10 CFR 50.36 (c)(2)(ii).

K/A MATCH ANALYSIS The question requires the candidate to utilize radiation monitors associated with Condenser Air Removal (1RE-0810) to recognize entry level for Tech Specs on RCS leakage. The candidate is then required to select which procedure will be utilzied based on the current primary to secondary leakage for plant shutdown.

EXPLANATION OF REQUIRED KNOWLEDGE Friday, February 21, 2014 3:43:48 PM 1

Per TS 3.4.13, 150 gpd primary to secondary LEAKAGE through any one steam generator exceeds allowable RCS operational LEAKAGE. In this condidtion, a shutdown to Mode 3 in 6 hrs and Mode 5 in 36 hrs is required. This shutdown can be accomplished using either the guidance of 12004-C or 18013-C. The decision is based on the characteristics of the leak and directed out of 18009-C.

Per 18009-C, if the tube leak is <5gpm and changing at a rate of < 30 gpd/hr, then a shutdown per 12004-C is sufficiently aggressive. If the tube leak is >5gpm or <5 gpm but changing at a rate >30 gpd/hr, then a more agressive shutdown utilizing 18013-C is necessary to ensure the plant is shutdown before the leak propogates into a rupture.

The rate of change is determined using 1RE-0724, N-16 Rad Monitor and/or 1RE-0810, SJAE Exhaust Rad Monitor, whose rate of change indications become valid after 20 mintues.

This decission tree is a complex set encompassing steps 5 thru 10 of 18009-C and is often mis-navigated. A high level understanding of steps are required to ensure internal self-checking of this operational decision.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is incorrect. Per TS 3.4.13, 150 gpd LEAKAGE in any steam generator exceeds the TS limit. Since both rad montiors have leakage below this value, the limit has not be exceeded. However, the threshold between a tube leak and a tube rupture is 120 gpm. Therefore, a candidate without sufficient knowledge of the TS limits could transpose in their minds the 120 and 150 values and conclude that the TS limit has been exceeded. Therefore, this distractor is plausible.

The second part is correct. Per 18009-C, with the leak rate <5 gpm and the rate of change > 30gpd/hr, a power reduction using 18013-C would be required.

B. Incorrect. Plausible. The first part is incorrect. See the first part of choice A above.

The second part is incorrect. Per 18009-C, with the leak rate

<5 gpm and the rate of change > 30gpd/hr, a power reduction using 18013-C would be required. However, a candidate without specific knowledge of the procedure decision tree values could conclude that the leak rate (120 gpd = 0.0833 gpm) is not sufficiently large to justify such an aggressive shutdown as 18013-C. Therefore, this distractor is plausible.

C. Correct. The first part is correct. Per TS 3.4.13, 150 gpd LEAKAGE in any steam generator exceeds the TS limit. Since both rad montiors have leakage below this value, the limit has not be exceeded.

The second part is correct. See the second part of choice A above.

(5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.

-Can the question be answered solely by knowing systems knowledge, i.e.,

how the system works, flowpath, logic, component location? No, the procedure direction decision is based out of NEI guidance on leak characteristics. It is not a logic decision, it is purely based on imperical data from the industry.

-Can the question be answered solely by knowing immediate operator actions?

No, the procedure knowledge required is not an IOA.

-Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, the procedure knowledge required is neither associated with entry conditions. It is specific to plant conditions the procedure utilizes to make operational decisions.

-Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, detailed and not overall knowledge of steps and sequencing is required to answer the question.

-Does the question require one or more of the following?

  • Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed Yes, the question requires the candidate to have a high level of understanding of the operational goals associated with a decision tree encompassed by 5 steps in AOP 18009-C which then determine the mitigating strategy that will be utilized.
  • Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps

Procedure titles are as follows:

- 18034-1, "Loss of Class 1E 125 VDC Power"

- 19000-C, "Reactor Trip or Safety Injection" Initial condition:

- Unit 1 is at 100% reactor power.

Current conditions:

- All Train 'A' MSIV red and green handswitch lights extinguish.

- RTB 'A' red and green lights extinguish.

- RCP #1 1E breaker red and green handswitch lights extinguish.

- Channel I TSLB bistable lights illuminate.

A. is is B. is is NOT C. is NOT is D. is NOT is NOT K/A 058 Loss of DC Power AA2.03 Ability to determine and interpret the following as they apply to the Loss of DC Power:

- DC loads lost; impact on ability to operate and monitor plant systems.

K/A MATCH ANALYSIS The question tests the candidates ability to relate multiple indications and the immediate impact to plant operations. They must interpret these various indications Friday, February 21, 2014 3:47:35 PM 1

and make a decision on which procedures would address the problem.

EXPLANATION OF REQUIRED KNOWLEDGE The indications given are the symptoms of a loss of power to 125VDC bus 1AD1. All 'A' train 1E switchgear breakers will loose control power. As such, the breaker will remain in its current state without electrical protection and all handswitch indication lights will be de-energized. The MSIVs and MFIVs will fail CLOSED as their solenoids are de-energized resulting in a Reactor Trip. All Channel I TSLBs lights will illuminate due to the loss of 1AY1A, which is normally feed from an inverter supplied by 1AD1.

Entry conditions for 18034-1 are met. Step 1 of 18034-1 directs a reactor trip and INITIATION of 19000-C. Per Admin procedure 10020-C step 3.3, "Initiate" means the referenced procedure will be used as a supplement to, and it will be performed concurrently with the one in effect. Therefore, 18034-C and 19000-C are expected to be worked in conjunction due to the complications resulting from a loss of DC.

18034-1 will address all issues required by the loss of the supported 120V Vital AC bus.

ANSWER / DISTRACTOR ANALYSIS A. Correct. The first part is correct. Entry conditions for 18034-1 are met.

The second part is correct, Step 1 of 18034-1 directs a reactor trip and INITIATION of 19000-C.

B. Incorrect. Plausible. The first part is correct. Entry conditions for 18034-1 are met.

The second part is incorrect. Per step 1 RNO of 18034-1, a reactor trip should have occured and is required. However, step 1 is not an IOA. A candidate without specific knowledge of the procedure and who did not realize the MISIVs could conclude the reactor did not trip and entry into 19000-C is not required. Therefore, this distractor is plausible.

C. Incorrect. Plausible. The first part is incorrect. The loss of indication on the associated handswitches and TSLBs indicate a loss of 1AD1.

However, a candidate with insufficient knowledge of power supplies could conclude that the handswitches are feed from 120V Vital AC and not the 125VDC supply. This is a common misconception. As such, it would be reasonable for the candidate to conclude a loss of 1AY1A to have occurred and entry into 18034-1 is not required. Therefore, this distractor is plausible.

The second part is correct. Step 1 of 18034-1 directs a reactor trip and INITIATION of 19000-C. However, a candidate that believes 18032-1 was entered instead of 18034-1, would still find it reasonable that the reactor would trip based on other trips. Therefore, this distractor is plausible.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

Friday, February 21, 2014 3:47:35 PM 2

The second part is incorrect. Step 1 of 18034-1 directs a reactor trip and INITIATION of 19000-C. However, a candidate that believes 18032-1 was entered instead of 18034-1 and has knowledge of 18032-1, would not expect the reactor to trip.

SRO JUSTIFICATION (10CFR43(b))

(5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.

-Can the question be answered solely by knowing systems knowledge, i.e.,

how the system works, flowpath, logic, component location? No, selection of the appropriate AOP/EOP combination is NOT associated with system knowledge.

-Can the question be answered solely by knowing immediate operator actions?

No, the direction to initiate 19000-C concurrent with 18034-C is the RNO of step 1 of 18034-C and is not an IOA.

-Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, the entry condition for each AOP/EOP is part of the question. However, the specific knowledge of 18034-C step 1 RNO is required. Normally, AOP use is discontinued upon entry into 19000-C. Most AOPs that direct tripping the reactor say "go to 19000-C", indicating that a transition to the EOP network is made. There are only a select few AOPs that required concurrent implementation of the AOP with the EOP. In most situation, the AOP is only performed at SS discretion and is typically not needed. 19000-C is designed to be successful with only one train of electrical power.

-Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, specific knowledge of 18034-C step 1 RNO is required.

-Does the question require one or more of the following?

  • Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed. Yes, the candidate is required to select the appropriate procedure/combination of procedures to mitigate the plant conditions.
  • Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps
  • Knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific subprocedures or emergency contingency procedures
  • Knowledge of administrative procedures that specify hierarchy, implementation, and/or coordination of plant normal, abnormal, and emergency procedures Level: SRO Tier # / Group # T1 / G1 K/A# 058AA2.03 Importance Rating: 3.5 / 3.9 Friday, February 21, 2014 3:47:36 PM 3

Question origin: BANK - HL15 NRC Question # 058AA2.03 Cognitive Level: C/A 10 CFR Part 55 Content: 41.7 / 41.10 / 43.5 Comments: Question appears to match the KA. Not sure if the procedure question is at the SRO-only level. The second question is systems knowledge and not at the SRO-only level.

Choices A-D have 4 different answers; the applicant does not need to know the answer to the second question to answer the question correctly.

The explanation states that an automatic reactor trip has occurred, however, the justification for the correct answer is that the RNO step for "Verify Reactor Trip," states to initiate 19000-C. Does this mean that, although it occurred automatically, Reactor Trip cannot be verified?

One possible fix could be dropping the second question (and anything in the stem that was solely used to answer the second question) and separate the first question to ask:

"the Shift Supervisor <is/is not> required to enter 18034-1 and the Shift Supervisor <is/is not> required to enter 19000-C."

(I still need to think about whether asking it this way is at the SRO-only level. I'm leaning towards it IS at the SRO-only level.)

- JAT 12/19/2013 (Editorial)

New question incorporates the above comments. SRO-only Friday, February 21, 2014 3:47:36 PM 4

1. 076A2.02 001/LOIT AND LOCT/SRO/C/A 2.7/3.1/076A2.02/LO-TA-60003/63013///

Initial conditions:

- Unit 1 is at 100% reactor power.

- SI Pump 'A' is tagged out.

Current conditions:

- Train B NSCW supply header pressure is 75 psig and lowering.

- Train 'B' NSCW supply header flow is 25,000 gpm.

- Train 'B' NSCW return header flow is 10,000 gpm.

- 18021-C, "Loss of Nuclear Service Cooling Water System," is entered.

Which one of the following completes the following statement?

Per 18021-C, the crew is required to __(1)__ the standby Train B NSCW pump, and after completing the actions of 18021-C, the Shift Supervisor will determine per 10008-C, "Recording Limiting Conditions for Operation," that a LOSF __(2)__ exist.

__(1)__ __(2)__

A. start does B. start does NOT C. place in PTL does D. place in PTL does NOT K/A 076 Service Water A2.02 Ability to (a) predict the impacts of the following malfunctions or operations on the SWS; and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations:

- Service water header pressure K/A MATCH ANALYSIS The question addresses a problem identified on an NSCW System to include low Monday, February 24, 2014 2:02:36 PM 1

header pressure and the candidate must determine the correct procedure action based on the indications provided. In addition, the candidates must determine the impact on plant operations using the information provided in the stem as related to LOSF evaluation. This concept brings the question to the SRO knowledge level.

EXPLANATION OF REQUIRED KNOWLEDGE Per 18021-C symptoms, a drop in NSCW header pressure accompanied by a large difference between supply and return header flows indicates a large (catastrophic) leak.

Per steps 1 and 2, all pumps in the affected train will be placed in PTL.

Since NSCW 'B' is a support system for all 'B' train ECCS pumps, a LOSF function exists with SIPs. With SIP 'A' tagged out in the stem and a subsequent loss of SIP 'B' due to loss of a support system, no medium head injection is available. Since TS 3.5.2 does not have a condition for two trains of ECCS inoperable, TS 3.0.3 must be entered.

(Reference 10008-C for LOSF evaluation guidance.)

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is incorrect however plausible since the candidate may believe the stem indications are due a pump problem such as a broken coupling, as opposed to a leak since the symptoms would be the same with exception of the supply and return flow deviation. Per 18021-C step 6, the correct action for this condition would be to start the standby pump.

Part 2 is correct. The candidate should determine that with both Train A SI Pump and Train B NSCW System inoperable a LOSF exists per 10008-C 'Recording Limiting Conditions for Operation'. However, if the candidate misses the catastrophic leak in Part 1, it would still be plausible for them to incorrectly determine that the standby NSCW pump is inoperable due to the failure to start on low header pressure and determine a LOSF exists for the wrong reason.

B. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice A above.

Part 2 is incorrect. The candidate should determine that with both Train A SI Pump and Train B NSCW System inoperable a LOSF exists per 10008-C 'Recording Limiting Conditions for Operation'. However, if the candidate misses the catastrophic leak in Part 1 and recognizes that the failure of the start on low header pressure in not a required function, then determining that a LOSF does not exist would be correct for these erroneous conditions..

C. Correct. Part 1 is correct. The candidate should determine that from the stem information provided that a large leak has occurred in the NSCW piping and the correct actions per 18021-C Loss of NSCW, is to place the affected pumps in PTL.

Monday, February 24, 2014 2:02:36 PM 2

Part 2 is correct. The candidate should determine that with both Train A SI Pump and Train B NSCW System inoperable a LOSF exists per 10008-C 'Recording Limiting Conditions for Operation'.

D. Incorrect. Plausible. Part 1 is correct. See Part 1 of choice C above.

Part 2 is incorrect however plausible since the candidate may not make the operability connection between the two systems or assume that NSCW could be run in single pump operations to supply cooling and therefore believe a LOSF condition is not present.

Approved By Procedure Version J.B. Stanley Vogtle Electric Generating Plant 10008-C 30 Effective Date Page Number 02/08/2013 RECORDING LIMITING CONDITIONS FOR OPERATION 3 of 32 1.0 PURPOSE 1.1 This procedure prescribes the method to record the failure to meet the Limiting Conditions for Operation (LCO), or Technical Requirement, the associated ACTION requirements, any change in status effecting the ACTION, and the return to compliance with LCO/TR.

1.2 This procedure also includes instructions for implementing Technical Specification 5.5.15, the Safety Function Determination Program. As required by LCO 3.0.6, this program ensures that proper actions are taken such that multiple inoperable Structures, Systems, or Components (SSC) do not result in an undetected LOSS OF SAFETY FUNCTION.

1.3 This procedure also ensures that the allowed out of service time of SUPPORTED SYSTEMS is not inappropriately extended as a result of multiple inoperable SUPPORT SYSTEMS.

2.0 PRECAUTIONS AND LIMITATIONS 2.1 Technical Specification LCO 3.0.2 states that the required Actions of an LCO MUST be performed when the requirements of the LCO are NOT met. LCO 3.0.6 provides an exception to LCO 3.0.2 for SUPPORTED SYSTEMS by NOT requiring the Required Actions for the SUPPORTED SYSTEMS to be performed WHEN the failure to meet an LCO is SOLELY due to the inoperability of a SUPPORT SYSTEM. In this situation, LCO 3.0.6 requires ONLY the Required Actions of the SUPPORT SYSTEM to be performed. Since cascading is NOT required in this case, a possibility exists that unrelated concurrent failures of more than one SUPPORT SYSTEM could result in the complete loss of both trains of a SUPPORTED SYSTEM. THEREFORE, upon a failure to meet two or more LCOs during the same time period, an evaluation SHALL be conducted to determine if a LOSS OF SAFETY FUNCTION (LOSF) exists. This LOSF Evaluation satisfies the criteria of Technical Specification Administrative Control 5.5.15, Safety Function Determination Program.

2.2 If the failure of a SSC not addressed by Technical Specification results in the inoperability of a required SUPPORT and/or SUPPORTED SYSTEM, then the LCO(s) for the required SUPPORT and/or SUPPORTED SYSTEM would be entered.

K/A MATCH ANALYSIS Monday, February 24, 2014 4:10:27 PM 1

The question sets up a plausible scenario which includes all the required KA elements.

First the SRO candidate must recognize in a timely manner the requirements for RCS sampling following the power reduction trend provided in the stem. Timely RCS activity sampling following a power reduction of more than 15% in one hour is required verify no fuel damage, which leads to high coolant activity. Then the candidate must determine the Tech Spec bases for lowering the energy level in the RCS if limits are exceeded.

EXPLANATION OF REQUIRED KNOWLEDGE TS SR 3.4.16.2 requires verification of DOES EQUIVALENT I-131 specific activity less than or equal to 1.0 uCi/gm between 2 and 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> following a power change of greater than or equal to 15% RTP within a 1 hr period. By definition, the 1 hr period is a rolling hour. As stated in the stem, the power change between 1100 and 1200 is 14%RTP.

The power change between 1115 and 1215 is 18%. Therefore, the 15% RTP in an hour has been exceeded.

Per TS 3.4.13, if I-131 is in excess of limits or LCO completion time of Cond A or B cannot be met, then the plant is required to be placed in Mode 3 with RCS Tavg <500F.

Per TS 3.4.13 Bases, with RCS Tavg <500F, the release of radioactivity in the event of a SGTR is unlikely since the saturation pressure of the reactor coolant is below the lift pressure settings of the main steam safety valve lift setpoint.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. Part 1 is correct the candidate should determine that from the stem information provided that a power reduction of more than 15% in one hour occured between 1115 and 1215 and require chemistry sampling of the RCS to verify no fuel damage.

Part 2 is incorrect however plausible since the candidate may determine that the bases for the RCS temperature limit is to prevent the ARVs from lifting since they would normally open an a lower setpoint.

B. Correct. Part 1 is correct. See Part 1 of choice A above.

Part 2 is correct. Per Tech Spec 3.4.16 Bases, the purpose of lowering RCS temperature below 500°F is to prevent radioactive releases due to main stream safety valves lifting.

C. Incorrect. Plausible. Part 1 is incorrect however plausible since the candidate may determine based on the time line given that RCS sampling is not required. The rolling hour starting at times 1100 and 1130 are <15% change.

Part 2 is incorrect. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is correct. See Part 2 of choice B above.

RCS specific activity satisfies Criterion 2 of 10 CFR 50.36 (c)(2)(ii).

LCO The specific iodine activity is limited to 1.0 Ci/gm DOSE EQUIVALENT I-131, and the gross specific activity in the reactor coolant is limited to the number of Ci/gm equal to 100 divided by (average disintegration energy of the sum of the average beta and gamma energies of the coolant nuclides).

The limit on gross specific activity ensures the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> whole body dose to an individual at the exclusion area boundary during the DBA will be a small fraction of the allowed whole body dose.

The SGTR accident analysis (Ref. 2) shows that the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> site boundary dose levels are within acceptable limits. Violation of the LCO may result in reactor coolant radioactivity levels that could, in the event of an SGTR, lead to exclusion area boundary doses that exceed the 10 CFR 100 dose guideline limits.

APPLICABILITY In MODES 1 and 2, and in MODE 3 with RCS average temperature t 500qF, operation within the LCO limits for DOSE EQUIVALENT I-131 and gross specific activity are necessary to contain the potential consequences of an SGTR to within the acceptable site boundary dose values.

For operation in MODE 3 with RCS average temperature < 500qF, and in MODES 4 and 5, the release of radioactivity in the event of a SGTR is unlikely since the saturation pressure of the reactor coolant is below the lift pressure settings of the main steam safety valves.

K/A G2.1.34 Knowledge of primary and secondary plant chemistry limits.

K/A MATCH ANALYSIS The question tests the candidate's knowledge of primary and secondary plant chemistry limits by requiring the student to select Tech Spec 3.7.16, "Secondary Specific Activity,"

specific activity limit for Dose Equivalent I-131 and the associated limiting design bases accident. This value is pitted against the limit for Tech Spec 3.4.16, "RCS Specific Activity".

EXPLANATION OF REQUIRED KNOWLEDGE Per Tech Spec 3.7.16, "Secondary Specific Activity" bases, the accident analysis of the main steam line break (MSLB), assumes the initial secondary coolant specific activity to have a radioactive isotope concentration of 0.10 µCi/gm DOSE EQUIVALENT I-131.

This assumption is used in the analysis for determining the radiological consequences of the postulated accident. The accident analysis, based on this and other assumptions, shows that the radiological consequences of an MSLB do not exceed a small fraction of the unit EAB limits for whole body and thyroid dose rates.

Per Tech Spec 3.4.16, "RCS Specific Activity" bases, the limit of 1.0 µCi/gm DOSE EQUIVALENT I-131 on specific activity of ensures that the doses are held to a small fraction of the 10 CRF 100 limits during a steam generator tube rupture accident. The maximum dose to the whole body and the thyroid considers exposure to an individual at the exclusion boundary for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

ANSWER / DISTRACTOR ANALYSIS A. Correct. Part 1 is correct. Per Tech Spec 3.7.16, Secondary Specific Activity, the specific activity of the secondary coolant shall be <

or = 0.10 µCi/gm DOSE EQUIVALENT I-131.

Part 2 is correct. Per Tech Spec 3.7.16, Secondary Specific Activity bases, the accident analysis of the main steam line break (MSLB), assumes the initial secondary coolant specific activity to have a radioactive isotope concentration of 0.10

µCi/gm DOSE EQUIVALENT I-131. This assumption is used in the analysis for determining the radiological consequences of the postulated accident. The accident analysis, based on this and other assumptions, shows that the radiological consequences of an MSLB do not exceed a small fraction of the unit EAB limits for whole body and thyroid dose rates.

B. Incorrect. Plausible. Part 1 is correct. See Part 1 of choice A above.

Part 2 is incorrect however plausible since the candidate may Tuesday, February 25, 2014 9:36:10 AM 1

recall the LOSP as the most limiting accident not taking into account the remaining steam generators are available for core decay heat dissipation by venting steam to the atmosphere through the MSSVs and steam generator atmospheric dump valves (ARVs). The Auxiliary Feedwater System supplies the necessary makeup to the steam generators. Venting continues until the reactor coolant temperature and pressure have decreased sufficiently for the Residual Heat Removal System to complete the cooldown.

C. Incorrect. Plausible. Part 1 is incorrect however plausible since its reasonable to assume the candidate may confuse primary limit for specific activity with the secondary limit since the numbers are only distinguish by the movement of the decimal point.

Part 2 is correct. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is correct. See Part 2 of choice B above.

B 3.4.16 RCS Specific Activity BASES BACKGROUND The maximum dose to the whole body and the thyroid that an individual at the exclusion area boundary can receive for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> during an accident is specified in 10 CFR 100 (Ref. 1). The limits on specific activity ensure that the doses are held to a small fraction of the 10 CFR 100 limits during analyzed transients and accidents.

The RCS specific activity LCO limits the allowable concentration level of radionuclides in the reactor coolant. The LCO limits are established to minimize the offsite radioactivity dose consequences in the event of a steam generator tube rupture (SGTR) accident.

The LCO limits specific activity for both DOSE EQUIVALENT I-131 and gross specific activity. The allowable levels are intended to limit the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> dose at the exclusion area boundary to a small fraction of the 10 CFR 100 dose guideline limits. The limits in the LCO are standardized, based on parametric evaluations of offsite radioactivity dose consequences for typical site locations.

The parametric evaluations showed the potential offsite dose levels for a SGTR accident were an appropriately small fraction of the 10 CFR 100 dose guideline limits. Each evaluation assumes a broad range of site applicable atmospheric dispersion factors in a parametric evaluation.

APPLICABLE The limits on the specific activity of the reactor coolant SAFETY ANALYSES ensures that the resulting 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> doses at the site boundary will not exceed a small fraction of the 10 CFR 100 dose guideline limits following a SGTR accident. The SGTR safety analysis (Ref. 2) assumes that the reactor has been operating at the maximum allowable Technical Specification limit for primary coolant activity and primary to secondary leakage for sufficient time to establish equilibrium concentrations of radionuclides in the reactor coolant and in the secondary coolant.

Vogtle Units 1 and 2 B 3.4.16-1 Revision No. 0

Secondary Specific Activity B 3.7.16 BASES (continued)

APPLICABLE The accident analysis of the main steam line break (MSLB),

SAFETY ANALYSES as discussed in the FSAR, Chapter 15 (Ref. 2) assumes the initial secondary coolant specific activity to have a radioactive isotope concentration of 0.10 Ci/gm DOSE EQUIVALENT I-131. This assumption is used in the analysis for determining the radiological consequences of the postulated accident. The accident analysis, based on this and other assumptions, shows that the radiological consequences of an MSLB do not exceed a small fraction of the unit EAB limits (Ref. 1) for whole body and thyroid dose rates.

With the loss of offsite power, the remaining steam generators are available for core decay heat dissipation by venting steam to the atmosphere through the MSSVs and steam generator atmospheric dump valves (ARVs). The Auxiliary Feedwater System supplies the necessary makeup to the steam generators.

Venting continues until the reactor coolant temperature and pressure have decreased sufficiently for the Residual Heat Removal System to complete the cooldown.

In the evaluation of the radiological consequences of this accident, the activity released from the steam generator connected to the failed steam line is assumed to be released directly to the environment. The unaffected steam generator is assumed to discharge steam and any entrained activity through the MSSVs and ARVs during the event. Since no credit is taken in the analysis for activity plateout or retention, the resultant radiological consequences represent a conservative estimate of the potential integrated dose due to the postulated steam line failure.

Secondary specific activity limits satisfy Criterion 2 of 10 CFR 50.36 (c)(2)(ii).

LCO As indicated in the Applicable Safety Analyses, the specific activity of the secondary coolant is required to be d 0.10 PCi/gm DOSE EQUIVALENT I-131 to limit the radiological consequences of a Design Basis Accident (DBA) to a small fraction of the required limit (Ref. 1).

Monitoring the specific activity of the secondary coolant ensures that when secondary specific activity limits are exceeded, appropriate actions are taken in a timely manner (continued)

(*) NPO - Individual with a Reactor Operator License.

Which one of the following completes the following statement?

Per TRM 15.1, "Unit Staffing," the total number of NPOs assigned __(1)__ meet the minimum required for the given conditions, and per NMP-OS-001, "Reactivity Management Program," any changes to the Unit 1 reactivity plan must be approved by the __(2)__.

__(1)__ __(2)__

A. does Reactivity Management SRO B. does Shift Supervisor C. does NOT Reactivity Management SRO D. does NOT Shift Supervisor K/A Conduct of Operations 2.1.37 Knowledge of procedures, guidelines, or limitations associated with reactivity management.

K/A MATCH ANALYSIS The question tests the candidate's knwoledge of administrative procedural requirements assoicated with the required approvals for changing reactivity plans during low power ascention following a reactor startup.

Tuesday, February 25, 2014 9:43:40 AM 1

EXPLANATION OF REQUIRED KNOWLEDGE The candidate is required to evaluate the minimum shift staffing for the given Modes per TRM 15.1 for the RO positions. Per Table 15.1.2-1, (3) ROs are required with both Units in Modes 1-4. (2) RO's must be assigned to the OATC position on each of the Units.

Per NMP-OS-001 step 6.1.2.1, the Shift Manager, who has ultimate responsibility for controlling the reactor core, approves formal Reactivity Management Plans as described in paragraph 6.6. The Shift Supervisor, or a designated Senior Reactor Operator, directly supervises reactivity changes. A written plan is developed by reactor engineering and approved for significant reactivity changes. The Shift Manager, Shift Supervisor, OATC, Shift Technical Advisor, and Reactor Engineer concur on Reactivity Management Plans and changes thereto, prior to implementation.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is correct. Per TRM 15.1 Table 15.1.2-1, (3) ROs are required with both Units in Modes 1-4. (2) RO's must be assigned to the OATC position on each of the Units. This condition is met.

The second part is incorrect. Per NMP-OS-001 step 6.1.2.1, the Shift Manager, Shift Supervisor, OATC, Shift Technical Advisor, and Reactor Engineer concur on Reactivity Management Plans and changes thereto, prior to implementation. However, the Reactivity Management SRO has oversight of all reactivity changes. As such, it is reasonable for a candidate without specific knowledge of the procedural requirements to assume the Reactivity Management SRO would also have this authority. Therefore, this distractor is plausible.

B. Correct. The first part is correct. See the first part of choice A above.

The second part is correct. Per NMP-OS-001 step 6.1.2.1, the Shift Manager, Shift Supervisor, OATC, Shift Technical Advisor, and Reactor Engineer concur on Reactivity Management Plans and changes thereto, prior to implementation.

C. Incorrect. Plausible. The first part is incorrect. Per TRM 15.1 Table 15.1.2-1, (3)

ROs are required with both Units in Modes 1-4. (2) RO's must be assigned to the OATC position on each of the Units. This condition is met. However, administrative procedure 00012-C Shift Manning limits are not currently met. Per 00012-C, the ENN communication position is normally filled by each of the UOs which results in (4) NPOs being required. This is the normal shift alignment. It is reasonable for a candidate who does not have adequate knowledge of TRM 15.1 requirements to determine insufficient NPOs exist. Therefore, this distractor is plausible.

Tuesday, February 25, 2014 9:43:40 AM 2

The second part is incorrect. See the second part of choice A above.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice C above.

The second part is correct. See the second part of choice B above.

Southern Nuclear Operating Company Nuclear NMP-OS-001 Management Reactivity Management Program Version 17.0 Procedure Page 9 of 39 6.1.2 Expectations 6.1.2.1 Reactivity Management Controls NOTE: Prior to implementing any activity that has the potential to add positive reactivity; the plant shall be ramped down, as necessary, to ensure that the reactor does not exceed 100.0% of the unit's Rated Thermal Power limit.

Reactivity management involves a systematic process of controlling evolutions with the potential to affect reactivity:

Planned reactivity changes are conducted in a controlled and conservative manner Unexpected changes in reactivity are minimized Conservative actions are taken in response to unexpected reactivity changes Reactivity control systems, including reactivity monitoring instrumentation, are available and reliable Modifications, analyses, and predictions are correct and effectively implemented The Shift Manager, who has ultimate responsibility for controlling the reactor core, approves formal Reactivity Management Plans as described in paragraph 6.6. The Shift Supervisor, or a designated Senior Reactor Operator, directly supervises reactivity changes.

A strong relationship exists between reactor engineering and operations. Reactor engineering is actively engaged in the planning of significant reactivity changes such as reactor startup, reactor shutdown, planned power changes, and special tests with the potential to affect reactivity. A written plan is developed by reactor engineering and approved for significant reactivity changes. The Shift Manager, Shift Supervisor, OATC, Shift Technical Advisor, and Reactor Engineer concur on Reactivity Management Plans and changes thereto, prior to implementation.

6.1.2.2 Control Room Operations Only operators with an active license (NPO or SRO) manipulate the controls of the reactor. An individual in a NRC-approved license training program may manipulate reactor controls when under the direction and in the presence of a licensed operator.

The OATC obtains concurrence from the Shift Supervisor prior to allowing or performing planned reactivity manipulations. Directions that affect reactivity go through the Shift Supervisor.

A briefing is conducted prior to the start of a planned reactivity change. The reactor operator performing rod movement, the OATC and Shift Supervisor monitor reactivity manipulations and verify that the end state of the reactivity manipulation is as expected.

Initial condition:

- ALB34-D01 125 VDC SWGR 1AD1 TROUBLE is received due to a bus ground.

Current conditions:

- Per NMP-AD-002, "'Problem Solving and Troubleshooting Guidelines," a troubleshooting plan has been written.

- As part of the plan, operations personnel will open various breakers and maintenance personnel will open links to measure resistance inside the 1AD1 panel.

Which one of the following completes the following statement?

This type of Troubleshooting Monitoring is called __(1)__,

and the tracking of the equipment out-of-service time while troubleshooting 1AD1 is the responsibility of the __(2)__ Department.

A. (1) Intrusive (2) Maintenance B. (1) Intrusive (2) Operations C. (1) Non-Intrusive (2) Maintenance D. (1) Non-Intrusive (2) Operations G2.2.20 Equipment Control Knowledge of the process for managing troubleshooting activities.

K/A MATCH ANALYSIS:

The candidate is presented with a plausible scenario where Troubleshooting is to be performed in the 1AD1 Panel by both maintenance personnel and operations personnel. The activity involves opening links, breakers and measuring resistance to Tuesday, February 25, 2014 10:15:47 AM 1

resolve a ground problem. The candidate must determine if this is intrusive or non-intrusive trouble shooting and also has to determine the person responsible for maintaining the system status of the panel during Trouble Shooting activities.

EXPLANATION OF REQUIRED KNOWLEDGE Per NMP-AD-002 definition 3.5, non-intrusive monitoring is defined as the act of monitoring a component or system by not affecting normal oepration of the conponent or system.

Per NMP-AD-002 definition 3.6, intrusive monitoring is defined as the act of temporarily altering the system to allow monitoring a component or system. This applies to electrical or mechanical testing methods.

Per NMP-AD-002 responsibility 4.2, the Operation Department is responsible for maintaining approved system status during troubleshooting activities (ie Out of Service).

ANSWER / DISTRACTOR ANALYSIS:

A. Incorrect. Plausible. Part 1 is correct. Opening breakers by Operations and opening links by Maintenance is an intrusive troubleshooting per NMP-AD-002.

Part 2 is incorrect. Operations Department is responsible for tracking systems status, however the answer is 'plusable' because opening links, measuring resistance, etc. would all be maintenance activities and some amount of individual component status control is required. These components are typically tracked using a "lifted lead" sheet inside the MWO.

Even though maintenance tracks status of some components, Operations still retains overall responsibility for ensuring equipment status and configuration control.

B. Correct. Part 1 is correct. See Part 1 of choice A above.

Part 2 is correct. Per NMP-AD-002 responsibility 4.2, the Operation Department is responsible for maintaining approved system status during troubleshooting activities.

C. Incorrect. Plausible. Part 1 is incorrect however 'plusable' because the word intrusive is very subjective and would require procedure knowledge to make this distinction. The candidate may determine that allowing intrusive troubleshooting on 1AD1 with the unit on line would imply too much risk to operations and thus eliminate this possibility.

Part 2 is incorrect. See Part 2 of choice A above.

D. Incorrect. Plausible. Part 1 is incorrect. See Part 1 of choice C above.

Part 2 is correct. See Part 2 of choice B above.

Tuesday, February 25, 2014 11:49:11 AM 1

EXPLANATION OF REQUIRED KNOWLEDGE Per TS SR 3.5.4.1, the RWST borated water temperature must be maintained greater than or equal to 44°F and less than or equal to 116°F. Per TS 3.5.4 Bases, the maximum temperature ensures that the amount of cooling provided from the RWST during the heatup phase of a feedline break is consistent with the safety analysis assumptions. The minimum temperature is an assumption in both the MSLB and inadvertent ECCS actuation. The inadvertent ECCS actuation is typically non-limiting.

Per TS SR 3.5.4.1, the RWST borated water must be maintained greater than or equal to 686,000 gallons. Per Tech Spec rounds OSP 14000-1, 686,000 gallons corresponds to an indicated level of 94%. Per TS 3.5.4 Bases, the RWST volume is an explicit assumption for LOCA events. The desired volume limit is set by LOCA and containment analyses. The volume is not an explicit assumption for non-LOCA events since the required volume is a small fraction of the available volume. The deliverable volume is different from the total volume contained since, due to the design of the tank, more water can be maintained than can be delivered.

ANSWER / DISTRACTOR ANALYSIS A. Incorrect. Plausible. The first part is correct. 93% level will place the unit in a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> shutdown.

The second part is incorrect. RWST level ensures sufficient injection volume for a DBA LOCA, not a DBA MSLB. However, Safety Injection is required to mitigate a main steam line break and requires suction from the RWST, but is not a limiting factor since the required volume would be a small fraction of that available.

B. Correct. The first part is correct. See the first part of choice A above.

The second part is correct. Per TS 3.5.4 Bases, the RWST volume is an explicit assumption for LOCA events C. Incorrect.Plausible. The first part is incorrect. Per TS SR 3.5.4.1, the RWST borated water temperature must be maintained greater than or equal to 44°F and less than or equal to 116°F.

The second part is incorrect. Per TS 3.5.4 Bases, the maximum temperature ensures that the amount of cooling provided from the RWST during the heatup phase of a feedline break is consistent with the safety analysis assumptions, not a main steamline break.

D. Incorrect.Plausible. The first part is incorrect. See the first part of choice C above.

The second part is the correct for the first part. Per TS 3.5.4 Bases, the maximum temperature ensures that the amount of cooling provided from the RWST during the heatup phase of a Tuesday, February 25, 2014 11:49:11 AM 2

RWST B 3.5.4 BASES BACKGROUND reduction of SDM or excessive boric acid precipitation in the core (continued) following the LOCA, as well as excessive stress corrosion of mechanical components and systems inside the containment.

APPLICABLE During accident conditions, the RWST provides a source of SAFETY ANALYSES borated water to the ECCS and Containment Spray System pumps.

As such, it provides containment cooling and depressurization, core cooling, and replacement inventory and is a source of negative reactivity for reactor shutdown (Ref. 1). The design basis transients and applicable safety analyses concerning each of these systems are discussed in the Applicable Safety Analyses section of B 3.5.2, "ECCS Operating"; B 3.5.3, "ECCS Shutdown"; and B 3.6.6, "Containment Spray and Cooling Systems." These analyses are used to assess changes to the RWST in order to evaluate their effects in relation to the acceptance limits in the analyses.

The RWST must also meet volume, boron concentration, and temperature requirements for non-LOCA events. The volume is not an explicit assumption in non-LOCA events since the required volume is a small fraction of the available volume. The deliverable volume limit is set by the LOCA and containment analyses. For the RWST, the deliverable volume is different from the total volume contained since, due to the design of the tank, more water can be contained than can be delivered. The minimum boron concentration is an explicit assumption in the main steam line break (MSLB) analysis to ensure the required shutdown capability. The maximum boron concentration is an explicit assumption in the inadvertent ECCS actuation analysis, although it is typically a nonlimiting event and the results are very insensitive to boron concentrations. The maximum temperature ensures that the amount of cooling provided from the RWST during the heatup phase of a feedline break is consistent with safety analysis assumptions; the minimum is an assumption in both the MSLB and inadvertent ECCS actuation analyses, although the inadvertent ECCS actuation event is typically nonlimiting.

The MSLB analysis has considered a delay associated with the interlock between the VCT and RWST isolation valves, and the (continued)

Vogtle Units 1 and 2 B 3.5.4-3 Revision No. 0

RWST B 3.5.4 BASES APPLICABLE results show that the departure from nucleate boiling design SAFETY ANALYSES basis is met. The delay has been established as 27 seconds, (continued) with offsite power available, or 39 seconds without offsite power (includes 12 seconds for the Emergency Diesel Generator). This response time includes an electronics delay, a stroke time for the RWST valves, and a stroke time for the VCT valves.

For a large break LOCA analysis, the minimum water volume limit of 499,091 gallons and the lower boron concentration limit of 2400 ppm are used to compute the post LOCA sump boron concentration necessary to assure subcriticality. The large break LOCA is the limiting case since the safety analysis assumes that all control rods are out of the core.

The upper limit on boron concentration of 2600 ppm 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.

In the ECCS analysis, the containment spray temperature is assumed to be equal to the RWST lower temperature limit of 44qF. If the lower temperature limit is violated, the containment spray further reduces containment pressure, which decreases the rate at which steam can be vented out the break and increases peak clad temperature. (The reduction in containment pressure correspondingly reduces the density of the vented steam. This reduces the flow of steam out of the core, which translates into a decrease in the ECCS flooding rate. This decrease in the flooding rate causes the increase in peak clad temperature.) The upper temperature limit of 116qF is used in the small break LOCA analysis and containment OPERABILITY analysis.

Exceeding this temperature will result in a higher peak clad temperature, because there is less heat transfer from the core to the injected water for the small break LOCA and higher containment pressures due to reduced containment spray cooling capacity. For the containment response following an MSLB, the lower limit on boron concentration and the upper limit on RWST water temperature are used to maximize the total energy release to containment.

The RWST satisfies Criterion 3 of 10 CFR 50.36 (c)(2)(ii).

K/A MATCH ANALYSIS:

The candidate is presented with a scenario where an Auxiliary Building Operator is required to enter several rooms with high dose rates in the area. The Operator is also on the verge of exceeding his Annual TEDE limits of 4000 mrem. The candidate has to determine the minimum level of authority that may approve exceeding the annual TEDE limits.

EXPLANATION OF REQUIRED KNOWLEDGE Per NMP-HP206 step 5.3.31.2 states that RED RWPs are "Single Use" type briefings.

Step 5.3.11.1.4 defines Single Use as "individuals must be authorized and the authorization is good for one entry only."

Per NMP-HP-001 step 6.2.3, there are 3 different administrative levels that require 3 different levels of approval:

2. 4000 mrem in a year requres AGM or Plant General Manager approval.
3. 4500 mrem in a year requires Project Vice President approval.

Dose in excess of 5mrem requires special NRC approval for normal operation, ED approval during emergencies. These different admin limits do not have a noun description/name and therefore are generally referred to by the associated dose limit.

DISTRACTOR ANALYSIS:

6.2.3.3 4500 mrem in a year requires Project Vice President approval.

6.2.4 Discrepant Dosimeter Investigation Criteria An assessment of workers dose should be initiated for discrepant dosimetry results when the following criteria are met: the primary or secondary dosimeter dose exceeds 100 mrem; and the secondary dosimeter reading differs by more than 25% from the primary dosimeter.

6.2.5 Dose Monitoring Threshold All individuals entering an RCA will be monitored for radiation exposure. A single dosimeter suffices for Visitors or Radiation Workers whose annual dose from sources external to the body is not expected to exceed 100 mrem at a particular station. An Optically Stimulated Luminescent Dosimeter (OSLD) and a self-reading dosimeter, such as an Electronic Dosimeter (ED), will be provided to all other individuals.

6.2.6 Training Requirements for Visitors or Temporary Radiation Workers Who Enter RCAs All SNC plants will administer training to all who must enter the RCAs in the following manner:

6.2.6.1 If the individual is expected to receive < 100 mrem in a year, the individual will be escorted by a GET qualified worker and will be provided instructions.

6.2.6.2 If the individual is expected to receive >100 and <500 mrem in a year, the individual will receive a visitor handout (containing all of the instruction elements required by 10CFR19.12) and will acknowledge receipt of the instructions or handout by signing a form. The individual will have a GET-trained radiological escort. If special circumstances dictate that entries into contaminated areas are required, the individual will receive dress-out training (if he has no history of such training at our plants). Similarly, if the individual requires entry to high radiation areas, special training or instructions may be required.

6.2.6.3 If the individual is expected to receive >=500 mrem in a year, the individual is required to complete GET which includes testing. If the individual has previous GET training at a nuclear facility within the past two years or as allowed by the Training Department, then exemption GET and the exemption GET test can be administered.

- ALB37-A01 4160V SWGR 1BA03 TROUBLE alarms, then subsequently clears.

- ALB38-F10 DG1B EMERGENCY START The question stem states that the plant is in Mode 6 and 20 minutes has elapsed since the loss of power event occured. Per NMP-EP-110 Figure 3, an NOUE should be classified based on Loss of All Offsite Power to Essential Buses for GREATER THAN 15 minutes and one EDG is supplying the 4160VAC bus.

An upgrade to an ALERT would occur if at any time the 1B DG fails to keep 1BA03 energized.

On NMP-EP-110 Figure 2, there are two similar classifications. The ALERT threshold is the same as the NOUE threshold in Mode 6. The difference arise out of a requirement to maintain 1 train in Mode 6 and 2 trains in Modes 1-4. A similar NOUE also exist for a Loss of All Offsite Power to Essential Buses for GREATER THAN 15 minutes and one EDG is supplying each of the 4160VAC buses.

ANSWER / DISTRACTOR ANALYSIS:

A. Incorrect. Plausible. CU3 is the correct classification. However, if the candidate does not recognize that 1BA03 is energized by the 1B DG and believes both 4160V buses are de-energized, then CA3 would be the correct classificaton.

B. Incorrect. Plausible. CU3 is the correct classification. However, if the candidate incorrectly utilizes NMP-EP-110 Figure 2 instead of Figure 3, then SA5 would match the conditions of the stem for the, but for the incorrect mode.

C. Incorrect. Plausible. CU3 is the correct classification. However, if the candidate incorrect diagnoses 1AA02 and believes it is energized by the 1A DG and also incorrect utilizes NMP-EP-110 Figure 2 instead of Figure 3, then SU1 would be the correct threshold.

D. Correct. CU3 is the correct classification. Loss of All Offsite Power to Essential Buses for GREATER THAN 15 minutes and one EDG is supplying the 4160VAC bus in Mode 6.

Tuesday, January 21, 2014 4:27:30 PM 1

ANSWER / DISTRACTOR ANALYSIS:

A. Incorrect. CA3 is a Cold Matrix classification, the plant is in Mode 4, not Mode 5 or 6. The mode was NOT stated in the question but just an RCS temperature given to increase the plausibility the candidate may select the wrong classification matrix. If the candidate selects the wrong matrix with the given alarms, it is plausible he could misinterpret the event and classify wrong. With the multiple alarms and indications, this can easily occur.

B. Correct. SA5 is the correct classification using the Hot Matrix, this is still a difficult determination with the multiple annunciator windows illuminated. The plant is only one failure away from a total plant blackout in this condition but the candidate has to determine this and correlate the event has been ongoing for > 15 minutes.

C. Incorrect. SU1 is a Hot Matrix classification. The plant is only one failure away from a total plant blackout in this condition but the candidate has to determine this and correlate the event has been ongoing for > 15 minutes. This choice is very plausible as the only difference between this and SA5 is that both diesels have to be carrying the buses to classify as SU1 versus 1 DG as in the correct choice.

This is a difficult determination with the mulitiple annuciators illuminated.

D. Incorrect. CA3 is a Cold Matrix classification, the plant is in Mode 4, not Mode 5 or 6. The mode was NOT stated in the question but just an RCS temperature given to increase the plausiblity the candidate may select the wrong classification matrix. IF, the plant were in Mode 5 and the Cold Matrix required to be used, this choice would then be correct.

- Adherence to appropriate procedures and operation within the limitations in the facility's license and amendments K/A MATCH ANALYSIS Thursday, February 27, 2014 9:13:31 AM 1

The question requires the candidate to make two decisions based on plant conditions while in 19111-C, "Loss of Emergency Coolant Recirculation" - stopping all ECCS pumps and transitioning out of 19111-C. Both decisions challenge the candidate's ability to adhere to the rules for using EOPs in compliance with WOG and facility requirements. Actions taken in accordance with these EOPs are part of the bases for granting the facility's license.

EXPLANATION OF REQUIRED KNOWLEDGE Per 19111-C steps 6 and 33 if RWST level lowers to <8%, all ECCS pumps taking suction from the RWST are to be placed in Pull-to-Lock (PTL).

Transition to any ORANGE or RED CSFST will be made when conditions are met. Per the rules of EOP usage, CSFSTs are initiated when either step 22 of 19000-C is reached, or a transition out of 19000-C is made. CSFSTs remain in effect during the entire EOP network unless otherwise directed. 19111-C does NOT contain any exceptional guidance on CSFST implementation.

ANSWER / DISTRACTOR ANALYSIS A. Correct. The first part is correct. Per continuous actions step 6 and steps 33 and 34, if RWST lowers to <8%, all ECCS pumps taking suction from the RWST are placed in PTL.

The second part is correct. CSFST monitoring was initiated on transition out of 19000-C. There is no guidance in 19111-C that prohibits actions based on CSFSTs. Therefore, a transition to 19241-C will be made as soon as ORANGE path conditions are verified.

B. Incorrect. Plausible. The first part is incorrect. Per continuous actions step 6 and steps 33 and 34, if RWST lowers to <8%, all ECCS pumps taking suction from the RWST are to be placed in PTL.

However, step 15 does reduce ECCS flow to only one train.

This is a mitigation strategy that prolongs RWST inventory. A candidate who does not possess the knowledge of the overall mitigating strategy of 19111-C could find it unreasonable to stop all ECCs pumps with a LOCA in progress and then transition to another procedure that does not address loss of injection flow.

The second part is correct. See the second part of choice A above.

C. Incorrect. Plausible. The first part is correct. See the first part of choice A above.

The second part is incorrect. There is no guidance in 19111-C that prohibits actions based on CSFSTs. Therefore, a transition to 19241-C would be made as soon as conditions for the ORANGE path are verified to exist. However, step 1 of EOP 19113-C, "Recirculation Sump Blockage" directs the operator to "initiate monitoring CSFSTs for information only. Function Thursday, February 27, 2014 9:13:31 AM 2

Restoration Procedures (FRP) should NOT be implemented." A candidate may confuse the two EOPs and believe transition out of 19111-C on CSFSTs is not allowed.

D. Incorrect. Plausible. The first part is incorrect. See the first part of choice B above.

The second part is incorrect. See the second part of choice C above.

SRO JUSTIFICATION (10CFR43(b))

(5) Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations.

-Can the question be answered solely by knowing systems knowledge, i.e.,

how the system works, flowpath, logic, component location? No, CSFSTs are symptom based, not system based.

-Can the question be answered solely by knowing immediate operator actions? No, stopping the ECCS pump and transitioning to FRPs is not governed by IOA's.

-Can the question be answered solely by knowing entry conditions for AOPs or plant parameters that require direct entry to major EOPs? No, the decisions made in the question require specific step knowledge.

-Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure? No, the decision to transition is based on specific parameters and direction.

-Does the question require one or more of the following?

  • Assessing plant conditions (normal, abnormal, or emergency) and then selecting a procedure or section of a procedure to mitigate, recover, or with which to proceed
  • Knowledge of when to implement attachments and appendices, including how to coordinate these items with procedure steps
  • Knowledge of diagnostic steps and decision points in the EOPs that involve transitions to event specific subprocedures or emergency contingency procedures. Yes, the question requires the SRO to make a transition decision to an FRP after stopping all ECCS pumps. The decision requires application of EOP rules of usage, knowledge of specific limitations on FRP implementation, and a high level knowledge of ECA and FRP mitigations strategy and interrelationships.
  • Knowledge of administrative procedures that specify hierarchy, implementation, and/or coordination of plant normal, abnormal, and emergency procedures Thursday, February 27, 2014 9:13:31 AM 3

Transitioning to the FRG's on an Orange path is not SRO-only knowledge.

Knowledge of what to do when RWST reaches 8% may be SRO-only knowledge. Since the 8% RWST does not govern a procedure transition, please make sure this is required knowledge of the operators (i.e., not minutia).
