| : 76. 008 AG2.4.2 076 Given the following:
| |
| Unit 1 at 100% power when a pressurizer safety valve failed open.
| |
| The operator manually tripped the reactor and initiated a safety injection.
| |
| While performing the step to determine if the RHR spray should be placed in service in accordance with E-1, "Reactor Trip or Safety Injection", the crew determines the following:
| |
| When pressurizer pressure dropped to 1280 psig, the safety valve reclosed and pressurizer pressure started to rise.
| |
| Containment pressure rose to 2.6 psig, and began trending down.
| |
| Pressurizer level is 100%.
| |
| RCS subcooling is 43°F.
| |
| - All four SG levels at 33% narrow range.
| |
| Which ONE of the following identifies the correct procedure implementation and operation of the RCPs for the above conditions?
| |
| A'I Transition from E-1 to ES-1.1, SI Termination; The RCPs will have remained running throughout the event.
| |
| B. Transition from E-1 to ES-1.1, SI Termination; The RCPs would have been shutdown but will be restarted in ES-1.1, SI Termination.
| |
| C. Continue E-1 until a transition is directed to ES-1.2, Post LOCA Cooldown; The RCPs will have remained running throughout the event.
| |
| D. A transition will be made to ES-1.2, Post LOCA Cooldown; The RCPs would have been shutdown but will be restarted in ES-1.2, Post LOCA Cooldown.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA C TOR ANAL YSIS:
| |
| A. CORRECT, with the safety valve reclosed and the conditions as identified in the stem, SI termination criteria is met. While the crew would be beyond the step in E-1 that first checks for SI termination and beyond the followup step for checking the criteria, the SI termination step is a continous action step and if the criteria is met the transition is to be made. Subcooling is greater than he 400F setpoint, pressurizer level above the 10%
| |
| setpoint, heat sink is established and RCS pressure rising meet the entry conditions for ES-1.1. Containment pressure did not rise to the automatic initiation setpoint of 2.8 psig (Phase B) nor did the RCS pressure drop to the 1250 psig setpoint, so the RCP trip criteria was not met and the pumps remained in service.
| |
| B. Incorrect, With the conditions identified in the stem, the SI termination criteria is met and a transition to ES-1.1 is required. The RCP trip criteria was not met and the pumps would have remained in service throughout the even. Plausible because the transition to ES-1.1 is the correct transition and if the RCPs had been stopped they would be restarted in ES-1.1.
| |
| C. Incorrect, While ES-1.2 would be entered if E-1 was continued, the conditions identified in the stem indicate SI termination criteria is met and a transition to ES-1.1 is required. The RCP trip criteria was not met and the pumps would have remained in service through out the event. Plausible because the transition to ES-1.2 would be the correct transition if the SI could not be terminated and the RCPs remaining in service through out the event is correct.
| |
| D. Incorrect, While ES-1.2 would be entered if E-1 was continued, the conditions identified in the stem indicate SI termination criteria is met and a transition to ES-1. 1 is required.
| |
| Because the RCP trip criteria was not met, the pumps would have remained in service through out the event. Plausible because the transition to ES-1.2 would be the correct transition if the SI could not be terminated and if the RCPs had been stopped they would be restarted in ES-1.2.

| - Unit 1 is operating at 100% power when a loss of offsite power occurs.
| |
| - The operators subsequently initiate Safety Injection due to a small break LOCA.
| |
| - Thirty minutes after the Safety Injection, the following conditions exist:
| |
| - E-1, "Loss of Reactor or Secondary Coolant" is being performed.
| |
| - All 4 SG pressures are approximately 1010 psig and stable.
| |
| - RCS pressure is 2230 psig and stable.

| ( DIS TRA CTOR ANAL YSIS:
| |
| A. Incorrect, Natural Circulation does not exist. Tcold (5600F) is approximately 10 degrees higher than saturation temperature of all 4 SGs (-54ffJF). Although SG pressures are at approximately the Atmospheric dump valve pressure, they mayor may not be open. The only way to tell if natural circulation exists is by trending Tcold. The transition to ES-O.2 from E-1 is not correct. Plausible because Thot lowering and Tcold stable could exist with natural circulation and ES-0.2 is a natural circulation procedure.
| |
| B. Incorrect, Natural circulation does not exist. Tcold (5600F) is approximately 10 degrees higher than saturation temperature of all 4 SGs (-54ffJF). The only way to tell if natural circulation exists is by trending Tcold. Steam dumps are unavailable due to the loss of offsite power. The transition to ES-1.2 from E-1 is correct. Plausible because Thot lowering and Tcold stable could exist with natural circulation and ES-1.2 is the correct procedure.
| |
| C. Incorrect, Natural circulation does not exist. Tcold (5600F) is approximately 10 degrees higher than saturation temperature of all 4 SGs (-54ffJF). The only way to tell if natural circulation exists is by trending Tcold. Steam dumps are unavailable due to the loss of offsite power. The transition to ES-0.2 from E-1 is not correct. Plausible because natural circulation does not exist (Core Exit temperatures rising) and ES-0.2 is a natural circulation procedure.
| |
| D. CORRECT, Natural Circulation does not exist. Tcold (5600F) is approximately 10 degrees higher than saturation temperature of all 4 SGs (-54ffJF). Although SG pressures are at approximately the Atmospheric dump valve pressure, they mayor may not be open. The only way to tell if natural circulation exists is by trending Tcold.

| Unit 1 is at 100% power.
| |
| RHR Pump 1B-8 is tagged for motor bearing maintenance.
| |
| - A Safety Injection occurs due to a LOCA.
| |
| RHR Pump 1A-A trips on instantaneous overcurrent when it attempts to start.
| |
| - As the crew transitions from E-1, Loss of Reactor or Secondary Coolant, to ECA-1.1, "Loss of RHR Sump Recirculation", the STA reports a RED path to FR-P.1, "Pressurized Thermal Shock".

| RWST level is 54% and dropping.
| |
| Which ONE of the following describes the required operator action?
| |
| A. The transition to FR-P.1 should NOT be made due to the ECA-1.1 entry requirement.
| |
| B. The transition to FR-P.1 should NOT be made until transfer to the containment sump is accomplished.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DISTRAGTOR ANAL YSIS:
| |
| A. Incorrect, The transition to FR-P.1 is required to be made from EGA-1.1.
| |
| Plausible because some other EGAs suspend the implementation of Status trees or direct the transition to FRGs not be made during the EGA performance.
| |
| B. Incorrect, The transition to FR-P.1 is required to be made from EGA-1.1.
| |
| Plausible because some other EGAs suspend the implementation of Status trees or direct the transition to FRGs not be made during the EGA performance until certain conditions are met and the establishment of sump recirculation is a priority for the given conditions.
| |
| G. Incorrect, The transition to FR-P.1 is required to be made and the transition back to EGA-1.1 is required but not because to the status of SI termination criteria. Plausible because FR-P.1, Step 3 does direct a return to the procedure in effect prior to reaching the SI Termination check which would also direct the same transition back to the instruction in effect.
| |
| D. GORREGT, The transition to FR-P.1 is required to be made and when FR-P.1 is entered, Step 3 will direct a return to the procedure in effect due to the RGS pressure being less than 300 psig along with both RHR pumps being stopped and sump recirculation capability loss.

| |
| : 79. 015 AA2.01 079 Given the following:
| |
| Unit 1 is at 32% power.
| |
| - The following annunciator windows alarm on 1-M-6:
| |
| FS-68-48A REACTOR COOLANT LOOP 3 LOW FLOW RCP BUS UNDERFREQUENCY 1 UNDERVOLTAGE RCP #3 indications are:
| |
| - Ammeter - '0' amps.
| |
| - Green and white lights above the handswitch are lit.
| |
| Flow - '0' on all 3 indicators.
| |
| - The other RCPs remain in service and the reactor trip breakers remain closed.
| |
| - The OATC manually trips the reactor as directed by the SRO.
| |
| Which ONE of the following identifies the condition causing the RCP trip and the earliest NRC notification required by 10CFR50. 72?
| |
| Condition causing RCP Trip Notification Requirement A. Under voltage 1 hour B~ Under voltage 4 hours C. Under frequency 1 hour D. Under frequency 4 hours Page 10
| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRACTOR ANAL YSIS:
| |
| The RCPs have protection from undervoltage and underfrequency via relays.
| |
| Both conditions can cause trips of the RCPs and if conditions and logic is met, the reactor would automatically trip.
| |
| A. Incorrect, The conditions in the stem describe the trip of RCP #3 from an undervoltage condition on the 6.9 Kv Unit Board feeding the RCP, however NO automatic trip would be initiated at the stated power level (below P8) and the emergency plan would not be implemented. (No 1 hour notification would be required). Plausible because the condition causing the RCP trip is correct and if the power level had been greater than P8, an automatic reactor trip should have occurred.. If the reactor had failed to trip automatically, a 1 hour report would be required due to implementation of the Emergency Plan.
| |
| B. CORRECT, The conditions in the stem describe the trip of RCP #3 from an undervoltage condition on the 6.9 Kv Unit Board feeding the RCP. With the reactor power level below P-8, no automatic reactor trip would be initiated from low flow condition in a single loop. AOP-R.04, Malfunction of Reactor Coolant Pump, would be the controlling procedure and at the stated power level, a manual reactor trip would be directed. The reactor trip would require a 4 hour notification.
| |
| C. Incorrect, The conditions in the stem describe the a trip of RCP #3 from an undervoltage condition on the 6.9 Kv Unit Board feeding the RCP not an underfrequency trip. The underfrequency trip of the RCP requires 214 logic to be made in the SSPS which then will trip the reactor and all RCPs. The logic is not met in the stem even though power is above the P7 permissive (10%), only one RCPs is involved and the logic requires 2 out of 4. NO automatic trip would be initiated at the stated power level (below P8) and the emergency plan would not be implemented. (No 1 hour notification would be required). Plausible because underfrequency can cause RCP trip with conditions different than stated in the stem and following the underfrequency initiation at greater than P7, a failure of the reactor to automatically trip would require a 1 hour due to the implementation of the Emergency Plan.

| D. Incorrect, The conditions in the stem describe the trip of RCP #3 from an undervoltage condition on the 6.9 Kv Unit Board feeding the RCP not an underfrequency trip. The underfrequency trip of the RCP requires 214 logic to be made in the SSPS which then will trip the reactor and all RCPs. The logic is not met in the stem even though power is above the P7 permissive (10%), only one RCPs is involved and the logic requires 2 out of 4. the 4 hour notification due to the manual reactor trip is correct. Plausible because underfrequency can cause RCP trip with conditions different than stated in the stem and the 4 hour notification due to the manual reactor trip is correct.

| |
| * A RCP may be stopped from its handswitch or at the switchgear. The (SD page 33) breaker will trip open on a motor protection fault (unit board UV, motor overcurrent) or an underfrequency trip of either reactor protection system train.
| |
| * In addition to providing a trip to the RCP, an UV trip signal provides an input to the reactor protection system (RPS). The purpose of the RPS trip is to provide DNB protection to the reactor by anticipating a complete loss of flow condition.
| |
| * This reactor trip requires an undervoltage condition (~70%) on two RCPs and is blocked below P-7 (10%).

| |
| J. Purpose/function of components COMPONENT PURPOSE / FUNCTION RCPUF logic
| |
| * An UF condition on two of the four RCP buses supplying the RCPs (SDpage 34) will initiate a reactor trip and trip all four RCP breakers. The purpose of the UF trip is to provide DNB protection to the reactor by anticipating a complete loss of flow condition in two or more loops.
| |
| * This reactor trip requires an underfrequency condition (~57 Hz) on two RCP buses and is blocked below P-7 (10%).
| |
| * A rapid decrease in electrical frequency can decelerate the RCPs faster than a complete loss of power. This trip, in conjunction with the rotational inertia provided by the RCP flywheel, ensures the proper flow coast-down time is maintained.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted SO. 022 AG2.1.28 080 Given the following:
| |
| Unit 1 is in Mid-Loop Operation with RHR Train A in service during a refueling outage with the reactor core reloaded.
| |
| SG nozzle dams are installed.
| |
| SI pump 1B-B is tagged and disassembled for impeller replacement CCP 1A-A trips due to motor failure.
| |
| RCS level begins to drop and the RHR pump 1A-A is stopped due to cavitation.
| |
| - Attempts to open 1-FCV-63-1, RHR Pump Suction from RWST, are unsuccessful.
| |
| Core exit thermocouples have increased to 20SoF.
| |
| Which ONE of the following identifies the procedure to be used and how SI pump IA-A will be aligned during performance of the procedure?
| |
| A. AOP-R02, "Shutdown LOCA".
| |
| SI pumps will be aligned for Hot Leg injection.
| |
| B. AOP-R02, "Shutdown LOCA".
| |
| SI pumps will be prevented from injecting due to LTOP requirements.
| |
| C~ AOP-R03, "RHR System Malfunction".
| |
| SI pumps will be aligned for Hot Leg injection.
| |
| D. AOP-R03, "RHR System Malfunction".
| |
| SI pumps will be prevented from injecting due to LTOP requirements.
| |

| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA CTOR ANAL YSIS:
| |
| A. Incorrect, AOP-R03 is the correct procedure to be used not AOP-R02. The AOP-R03 does direct the SI pumps to be aligned in Hot Leg injection. Plausible because the conditions in the stem would exist if a shutdown LOCA was occurring and if AOP-R02 were entered a note at the start of the AOP directs the use of AOP-R03 if the plant is in Mid-Loop operation and the SI pumps alignment in Hot Leg injection is correct.
| |
| B. Incorrect, AOP-R03 is the correct procedure to be used not AOP-R02 and the AOP directs the SI pumps to be aligned in Hot Leg injection. Plausible because the conditions in the stem would exist if a shutdown LOCA was occurring and if A OP-R 02 were entered a note at the start of the A OP directs the use of A OP-R 03 if the plant is in Mid-Loop operation and the SI pumps normal alignment with injection prevented due to the L TOPS requirement.
| |
| C. CORRECT, when the charging pump trips (loss of RCS makeup) the vessel level will start to decrease. When the RHR pump is stopped due to cavitation, core cooling flow is terminated, the core starts heating up and with 1-FCV-63-1 unable to be opened, the AOP -R03 directs the SI pumps to be aligned for Hot Leg Injection. A note prior to the step to align the pumps states that core cooling takes priority over the L TOPS requirements for the SI pumps. The conditions would be the same if a shutdown LOCA was occurring and if AOP-R02 was entered there is a note at the start of the A OP directing the use of A OP-R 03 if the plant is in Mid-Loop operation.
| |
| D. Incorrect, AOP-R03 is the correct procedure to be used but the AOP directs the SI pumps to be aligned in Hot Leg injection. Plausible because the procedure is the correct procedure to be used and and the SI pumps normal alignment is with injection prevented due to the L TOPS requirements.

| |
| NOTE Operation of main generator without automatic voltage control could impact grid voltage requirements. SELD should be notified immediately if automatic voltage regulator is lost.
| |
| Studies show that there is some risk of instability in the event of a fault at high side of SON 500/161 kV Intertie Transformer Bank plus a failure of a high side breaker to clear. Backup breakers would then take the entire 500kV bus section out of service. This double-fault event is not postulated to occur simultaneously with a LOCA and is therefore not a scenario used to determine nuclear offsite power adequacy. This is an issue related to grid reliability only and operating guidelines to ensure stability are included in this document for convenience.
| |
| SON Units 1 and 2 must observe generation limits under certain grid conditions in order to ensure stability under the above double-fault scenario.
| |
| Both Units are limited to a Maximum Outgoing Reactive Load of 240 Mvar. This limitation supports offsite power source qualification.
| |
| Transmission Reliability Organization's SON Grid Operating Guide directs that the Transmission Operator will notify the SON Generator Operator of any Mvar Limits recommended. Grid stabilization following the loss of an element depends on the coordination of multiple changes including SON reactive loading. Real time information on the factors affecting grid stability is not available to SON Operators, therefore the Transmission Operator will coordinate the effort. The limits provided in the following tables are for information only.

Incorrect, The SI will be terminated using AOP-C.04 Appendix F, Terminating SI flow not by the use of ES-1.1, SI Termination and with all MCR actions completed, the reactor coolant pumps are shutdown leaving the RCS cooldown to be trended by the SG pressure instruments which have a saturation temperature scale on them. Thot can only be used when the RCPs are in service. Plausible because procedure ES-1.1, SI Termination, is the procedure used for SI termination in many conditions and Thot could be used to monitor cooldown if the RCPs were in service.
| |
| B. Incorrect, The SI will be terminated using AOP-C.04 Appendix F, Terminating SI flow not by the use of ES-1.1, SI Termination. Since all MCR actions have been completed, the reactor coolant pumps are shutdown resulting in the steam generator pressure instruments being used to trend the RCS cooldown to be correct. Plausible because procedure ES-1.1, SI Termination, is the procedure used for SI termination in many conditions and the steam generator pressure instruments are used to monitor cooldown.
| |
| C. Incorrect, The SI will be terminated using AOP-C.04 Appendix F, Terminating SI flow but with all MCR actions completed, the reactor coolant pumps are shutdown leaving the RCS cooldown to be trended by the SG pressure instruments which have a saturation temperature scale on them. Thot can only be used when the RCPs are in service. Plausible because the procedure used for SI termination is correct and Thot could be used if the RCPs were in service.

| |
| Unit 1 is in Mode 3 with RCS at normal operating pressure and temperature awaiting secondary plant equipment repair to continue the startup.
| |
| - At 1300 on 01/25109 RCS Activity was determined to be 0.38 microcuries/gram DOSE EQUIVALENT 1-131.
| |
| - At 1300 on 01/27/09 Chemistry reports that the RCS Activity has been on a continuous slow increase and is now 0.43 microcuries/gram DOSE EQUIVALENT 1-131.
| |
| Which ONE of the following identifies actions that are required by 1900 on 01/27/09 and the bases for the RCS Specific Activity limit?
| |
| A. Reduce RCS Tavg below 500°F to limit doses at the site boundary in the event of a LOCA in conjunction with 0.25La leakage from containment.
| |
| B~ Reduce RCS Tavg below 500°F to limit doses at the site boundary in the event of a SGTR in conjunction with steady state SG tube leakage of 1 gpm.

| |
| Page 22
| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DISTRACTOR ANAL YSIS:
| |
| A. Incorrect, reducing Tavg below 500°F is correct but the bases is not due to a LOCA with assumed containment leakage. Plausible because the action stated is correct and a LOCA with leakage from containment could cause elevated doses at the site boundary.
| |
| B. CORRECT, with the activity above the 0.35 microcurieslgram limit in the Tech Spec 3.4.8 for 48 continuous hours, Tavg is required to be reduced to less than 500° F within 6 hours in accordance with the Tech Spec. The TIS bases states that reducing Tavg below 500°F prevents the release of activity should a steam generator tube rupture since the saturation pressure of the primary coolant is below the lift pressure of the atmospheric steam relief valves. The limit on activity is based on the resulting 2-hour doses at the site boundary not exceeding a small fraction of the 10 CFR 100 limits following a SGTR in conjunction with an assumed steady state SG tube leak of 1 gpm.
| |
| C. Incorrect, reducing Tavg below 350°F is not correct and the bases is not due to a LOCA with assumed containment leakage. Plausible because lowering Tavg to 350°F would mean changing to Mode 4 within the next 6 hours (which is a directed action in many TIS) and a LOCA with leakage from containment could cause elevated doses at the site boundary.
| |
| ( D. Incorrect, reducing Tavg below 350°F is not correct but the bases is being to limit doses in the event of a SGTR is correct. Plausible because lowering Tavg to 3500F would mean changing to Mode 4 within the next 6 hours (which is a directed action in many TIS) and the bases is to limit doses at the site boundary during SGTR accident.

| REACTOR COOLANT SYSTEM
| |
| ( BASES I
| |
| 3/4A8 SPECIFIC ACTIVITY The limitations on the specific activity of the primary coolant ensure that the resulting 2 hour doses at the site boundary will not exceed an appropriately small fraction of Part 100 limits following a steam generator tube rupture accident in conjunction with an assumed steady state primary-ta-secondary steam generator leakage rate of 1.0 GPM. The values for the limits on specific activity represent interim limits based upon a parametric evaluation by the NRC of typical site locations. These values are conservative in that specific site parameters of the Sequoyah Nuclear Plant site, such as site boundary locatio~ and meteorological conditions, were not considered in this evaluation ..
| |
| The ACTION statement permitting POWER OPERATION to continue for limited time periods with the primary coolant's specific activity greater than 0.35 microcuriesigram DOSE EQUIVALENT 1-131, but within the allowable limit shown on Figure 3.4-1, accommodates possible iodine spiking phenomenon which may occur following changes in THERMAL POWER Operation with specific activity levels exceeding 0.35 microcuriesigram DOSE EQUIVALENT 1-131 but within the limits shown on Figure 3.4-1 should be limited to no more than 800 hours per year since the activity levels allpwed by Figure 3.4-1 increase the 2-hour thyroid dose at the site boundary by a factor of up to 20 following a postulated steam generator tube rupture. A Note permits the use of the provisioris of LCO 3.0.4.c. This allowance permits entry into the applicable MODE(S) while relying on the ACTIONS. This allowance is acceptable due to the significant conservatism incorporated into the specific. activity limit, the low probability of an event which is limiting due to exceeding this limit, and the ability to restore transient specific activity excursions while the plant remains at, or proceeds to power operations ..
| |
| Reducing Tavg to less than 500°F prevents the release of activity should a steam generator tube rupture since the saturation pressure of the primary coolant is below the lift pres5'ureof the atmospheric steam reliefvalves. The surveillance requirements provide adequate assurance that excessive specific activity levels in the primary coolant will be detected insufficient time to take corrective action.
| |
| Information obtained on iodine spiking will be used to assess the parameters associated with spiking phenomefla. A reduction in frequency of isotopic analyses following power changes may be permissible if justified by the data obtained.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRACTOR ANAL YSIS:
| |
| A. Incorrect, if E-O is performed to the last step, the step will direct a loop back to step 8 so that a transition can be identified either to an accident procedure or to the procedure to terminate the safety injection. EPM-4, User's Guide does permit AOP performance while in the EOP network with the conditions stated in the stem. Plausible because the loop back in E-O is correct and the EOPs do have priority over the AOPs except under certain conditions.
| |
| B. CORRECT, if a transition is not made while E-O is performed the last step will direct a loop back to step 8 so that a transition can be identified either to an accident procedure or to the procedure to terminate the safety injection. EPM-4, User's Guide, does permit the AOP performance while in the EOP network with the conditions stated in the stem.
| |
| C. Incorrect, while ES-O.O, Rediagnosis, can be used to determine the correct procedure, it is not applicable until a transition is made from E-O. EPM-4, User's Guide does permit AOP performance while in the EOP network with the conditions stated in the stem.
| |
| Plausible because ES-O.O, Rediagnosis, can be used to determine the correct procedure under different conditions and the EOPs do have priority over the AOPs except under certain conditions.

| D. Incorrect, while ES-O.O, Rediagnosis, can be used to determine the correct procedure, it is not applicable until a transition is made from E-O. EPM-4, User's Guide does permit AOP performance while in the EOP network with the conditions stated in the stem.

| |
| K. Step 7 directs the operator to "CHECK SI termination criteria."
| |
| : 1. If all of the criteria in Substeps a through d are met, the operator remains in the AER column and transitions to ES-1.1 to terminate SI.
| |
| : 2. If any of the criteria in Substeps a through d are NOT met, the operator moves to the RNO column and proceeds to Step 8.
| |
| L. St~p"8 directs the operator to "GO TO E-1, Loss of Reactor or Secondary Coolant."
| |
| : 1. This step ends performance of procedure E-2 with a transition to E-1.
| |
| : 2. The highlighted word "END" centered after the last step emphasizes that the action steps for E-2 are complete.
| |
| 3.11.5 Use of ES-O.O, Rediagnosis A. ES-O.O, Rediagnosis, is unique among the EOPs in that it has no specific transition into it. It is entered strictly based on operator judgment and is applicable only if SI is in progress and E-O has already been performed (diagnostic steps completed and!.!:ansition made to another procedure).
| |
| ES-O.O should be used when the operator has any concern that he may not be in the right EOP based on plant conditions. This is most likely to happen if multiple accidents occur either simultaneously or sequentially.
| |
| B. Once entered, ES-O.O will either transition the operator to ECA-2.1, E-1, E-2, or E-3, or will return him to the procedure and step in effect, depending on
| |
| ,diagnostics done within the procedure. If ES-O.O determines that an operator should be in a certain series of procedures (e.g., E-1 or ECA-1 series), and he is, then he simply returns to the procedure and step in effect. If ES-O.O determines that an operator should be in a certain series of procedures (e.g.,
| |
| E-3 or ECA-3 series), and he is NOT, then he is sent to either E-1 (if he should be in E-1 or ECA-1 series) or E-3 (if he should be in E-3 or ECA-3 series) to enter the appropriate series at the beginning and work his way through the series normally from that point on.

| SQN EOI EPM-4 PROGRAM USER'S GUIDE Rev. 20 MANUAL Page 65 of 97 3.11.7 Use of AOPs Within the EOP Network A. EOPs have priority over AOPs at all times, except when a reactor trip or safety injection has occurred in conjunction with an Appendix R fire (AOP-N.08), Control Room abandonment(AOP-C.04), or Loss of all ERCW capability (AOP-M.01).
| |
| B. AOP performance while in the EOP network is allowable under the following two circumstances: [C.1]
| |
| : 1. AOPperformance is directed by EOPs in effect.
| |
| : 2. AOP performance is deemed necessary by the SM or US to address abnormal plant conditions NOT directly addressed by the EOPs but which have a significant impact on the ability of the EOPs to perform their function (e;g., loss of ERCW, CCS, off-site power, vital instrument power board, etc.) In this case, the following guidelines should be followed:
| |
| : a. Concurrent performance of the EOPs and the AOP should enhance, NOT degrade, the performance of EOPs in progress ..
| |
| : b. Manpower reSources are adequate to allow performing the EOPs and the AOP concurrently.
| |
| c.* The AOP should be performed using the single perfomer method so the procedure reader remains dedicated to the EOPs in progress, which are mitigative in nature. The SM may elect to deviate from this requirement when in ES-O.1.
| |
| : d. Certain AOPs may be required to be performed concurrently with the EOPs in order for the EOPs to function as intended; for example, loss of CCS, loss of ERCW, loss of air or vital power to equipment important to safety-- any of these could have a significant impact on the ability of the EOPs to achieve their goals.
| |
| : e. Upon transition to ES-O.1, the SM will designate the mitigating crew responsibilities as appropriate, based on the events in progress.
| |
| Normally, the procedure reader and OATC will perform ES-O.1 while the CRO performs the AOP using the single perfomer method.

| |
| A. Incorrect, the level is the sump is below the 68% level required to enter FR-Z. 2, Containment Flooding but if the level was high enough for entry the transition would be required. Plausible because the containment sump level is elevated and if the required level was present an Orange would be present and require immediate transition to FR-Z.2.
| |
| B. Incorrect, the level is the sump is below the 68% level required to enter FR-Z. 2, Containment Flooding but if the level was high enough for entry the transition would not be optional. Plausible because the containment sump level is elevated and if the required level being met resulted in a yellow path, the entry would be optional.
| |
| C. Incorrect, the radiation in lower containment is greater than the threshold level for entering FR-Z.3, High Containment Radiation, but the challenge is a Yellow path which allows the performance of the procedure to be optional. Only Red and Orange path challenges are required to be immediately implemented. Plausible because the entry conditions are met and if the challenge had been an Orange path, immediate transition would be required.
| |
| D. CORRECT, the radiation in lower containment is greater than the threshold level for entering FR-Z.3, High Containment Radiation, and the challenge is a yellow path which allows the performance of the procedure to be optional.

| 3.10.5 Status Tree Rules of Usage (continued)
| |
| : 6. If any ORANGE challenge is encountered, the person monitoring status trees continues monitoring until all six status trees have been evaluated.
| |
| This is necessary because a subsequent RED challenge has priority over any ORANGE challenge. If any RED is encountered, then Rule 3.10.5.0.4 applies. Otherwise, once it is determined that no RED challenges exist, then the person monitoring status trees informs the procedure reader of the highest priority ORANGE challenge.
| |
| : 7. RED or ORANGE challenges must be addressed immediately by implementing appropriate FRPs in order of priority and per the rules of usage. When the person monitoring status trees informs the procedure reader that a RED or ORANGE challenge exists, the procedure reader immediately suspends the ORP (or lower priority FRP) in progress and implements the appropriate FRP, as indicated at the terminus point of the CSF under challenge.
| |
| : 8. YELLOW challenges may be addressed by implementing appropriate FRPs if desired, but do not require immediate operator action.
| |
| Addressing YELLOW challenges is optional since these are usually temporary, off-normal conditions that will be restored to normal status by actions already in progress. In other cases, the YELLOW path might provide an early indication of a developing RED or ORANGE condition.
| |
| Following FRP implementation, a YELLOW might indicate a residual off-normal condition. When the person monitoring status trees informs the procedure reader that a YELLOW challenge exists, the procedure reader should evaluate if the YELLOW challenge FRP should be implemented.
| |
| This decision will be based on the following:
| |
| * Whether the procedures in effect will address the challenge as a matter of course.
| |
| * Whether the procedures in effect are more important at that time based upon available time and current plant conditions.
| |
| * Whether the challenge is of a nature that it will likely develop into an ORANGE or RED condition if action is not taken early.

| |
| ( Given the following:
| |
| Unit 1 in Mode 3 with RCS at normal operating temperature and pressure.
| |
| RCPs #1, #2 and #3 are running.
| |
| Following the start of RCP #4, the pump stabilizes as follows:
| |
| - Motor current at 625 amps.
| |
| - #1 sealleakoff at 1.1 gpm.
| |
| - All pump and motor temperatures stable and within limits.
| |
| - The operators implement AOP-R.04, "Reactor Coolant Pump Malfunctions".
| |
| Which ONE of the following identifies why AOP-R.04 entry was required and the action directed by the AOP?
| |
| A'I The AOP was entered due to the high motor current and the AOP will direct removal of the RCP from service.
| |
| B. The AOP was entered due to the high motor current but the AOP will NOT direct removal of the RCP unless bearing or stator temperatures are increasing.
| |
| C. The AOP was entered due to the low #1 seal leakoff flow and the AOP will direct removal of the RCP from service.
| |
| D. The AOP was entered due to the low #1 sealleakoff flow but the AOP will NOT direct removal of the RCP unless lower bearing or seal water temperatures are increasing.
| |
| Page 31
| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA CTOR ANAL YSIS:
| |
| A. CORRECT, the AOP entry was required due to the high current flow to the motor and the with the current flow greater than 608 amps, the procedure directs the RCP to be stopped.
| |
| B. Incorrect, the AOP entry being required due to the high current flow to the motor is correct but with the current flow greater than 608 amps, the procedure does not require the bearing or stator temperatures to be increasing to direct the RCP to be stopped. Plausible because the high motor current is why the procedure entry was required and increasing temperatures do result in stopping the RCP with other conditions in the procedure.
| |
| C. Incorrect, the AOP entry was not required due to low #1 sealleakoff flow as the leakoff is above the low flow alarm, and if the flow was low with the bearing and seal water temperature stable, the AOP would not require the pump be stopped unless the #1 sealleakoff flow was further reduced. Plausible because low seal leakoff flow would require the procedure to be entered and if the flow were low enough the stopping of the RCP would be required.
| |
| D. Incorrect, the AOP entry was not required due to low #1 sealleakoff flow but if the seal was less than entry conditions, rising temperature would result in stopping the RCP. Plausible because low sealleakoff flow would require the procedure to be entered and if the lower bearing or seal water temperatures were increasing, the stopping of the RCP would be required.

| ( 87. 026 G2.4.20 087 Given the following:
| |
| Unit 1 at 100% power with Containment Spray Pump 1A-A out of service and tagged.
| |
| - A LOCA results in a Reactor Trip and Safety Injection.
| |
| - After transferring to the containment sump the crew observes the amps fluctuating on Containment Spray Pump 1B-B.
| |
| In response, the crew stops the pump and transitions to ECA-1.3, "Containment Sump Blockage".
| |
| - The STA reports a RED path to FR-Z.1, "High Containment Pressure".
| |
| Which ONE of the following identifies the condition that results in the restart of Containment Spray Pump 1B-B and what would be the desired flow rate?
| |
| A. Due to implementing FR-Z.1 , the pump will be restarted and the desired flow rate is the DESIGN spray flow due to the challenge to the Containment Barrier.
| |
| B. Due to implementing FR-Z.1 , the pump will be restarted and the desired flow rate is the MINIMUM spray flow required to control containment pressure provided it does not cause the RHR pump to cavitate.
| |
| C. ECA-1.3 will restart the spray pump after TSC evaluation and the desired flow rate is the DESIGN spray flow due to the challenge to the Containment Barrier.
| |
| D!" ECA-1.3 will restart the spray pump after TSC evaluation and the desired flow rate is the MINIMUM spray flow required to control containment pressure provided it does not cause the RHR pump to cavitate.
| |

| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA CTOR ANAL YSIS:
| |
| A. Incorrect, when ECA-1.3 is entered FRGs are monitored for information only and the implementation of FRGs is suspended. Transition to FR-Z 1 will not be made and a note in the ECA Appendix E for throttling spray flow identifies the desired flow rate to be the MINIMUM to control containment pressure without causing cavitation of the RHR pump not the MAXIMUM without causing cavitation. Plausible because FR-Z 1 would restart the spray pump and with a RED path identified the Containment pressure is at or above the design pressure and a severe challenge to the barrier exists and establishing the maximum flow would cause a greater drop in containment pressure.
| |
| B. Incorrect, when ECA-1.3 is entered FRGs are monitored for information only and the implementation of FRGs is suspended. Transition to FR-Z 1 will not be made. A note in the ECA Appendix E for throttling spray flow identifies the desired flow rate is the MINIMUM to control containment pressure without causing cavitation of the RHR pump.
| |
| Plausible because FR-Z 1 would restart the spray pump and establishing the minimum flow to control containment pressure without causing cavitation of the RHR pump is correct for the conditions in the stem.
| |
| C. Incorrect, The FRGs are monitored for information only so ECA-1.3 is continued and the ECA directs the TSC evaluation if containment pressure is greater than 9.5 psig and the pressure would be with a RED path present (12psig). A note in the ECA Appendix E for throttling spray flow identifies the desired flow rate to be the MINIMUM to control containment pressure without causing cavitation of the RHR pump not the MAXIMUM without causing cavitation. Plausible because the ECA is the procedure which restart and control the pump and with a RED path identified the Containment pressure is at or above the design pressure and a severe challenge to the barrier exists and establishing the maximum flow would cause a greater drop in containment pressure.
| |
| D. CORRECT, A RED path on the Containment Status Tree occurs when the pressure is greater than 12 psig. The FRGs are monitored for information only so ECA-1.3 is continued. The ECA directs the TSC evaluation if containment pressure is greater than 9.5 psig and the pressure would be with a RED path present (12psig). A note in the ECA Appendix E for throttling spray flow identifies the desired flow rate is the MINIMUM to control containment pressure without causing cavitation of the RHR pump.

| : 89. 062 G2 4.18089 Given the following:
| |
| Unit 1 is operating at 100% power Diesel Generator 1B-B is out of service and is expected to return to service in 2 hours.
| |
| Subsequently, the following events occur:
| |
| - A loss of offsite power occurs.
| |
| - The reactor trips and the crew enters the emergency procedures.
| |
| - SI is NOT actuated.
| |
| - The crew transitions to FR-H.1, "Loss of Secondary Heat Sink" due to a RED Path condition and is performing the first step.
| |
| No other Status Tree RED paths are present.
| |
| - A fault on Shutdown Board 1A-A results in the emergency supply breaker from Diesel Generator 1A-A tripping due a differential relay.
| |
| Which ONE of the following identifies the correct action to be taken and the bases for the action?
| |
| A. Transition to ECA-O .0, Loss of All AC Power because the ECA will direct actions to establish heat sink with the TD-AFW pump.
| |
| B. Remain in FR-H.1 unless a higher priority RED path occurs because the FR will direct actions to establish heat sink with the TD-AFW pump.
| |
| C~ Transition to ECA-O .0, Loss of All AC Power because all other procedures in the EOP network assume a minimum of at least one 6.9kV Shutdown Board is available.
| |
| D. Remain in FR-H.1 and initiate actions to manually restore 6.9kV Shutdown Board 1B-B from 2B-B 6.9kV Shutdown Board maintenance breaker because restoring heat sink is the highest priority evolution in progress.
| |
| Page 40
| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA GTOR ANAL YSIS:
| |
| A. Incorrect, The transition to EGA-O.O is the correct action and the EGA will direct actions ensuring the TO AFW pump is in service but the reason is not because the EGA establishes the heat sink. Plausible because the transition is correct and EGA will direct actions to place the TO AFW pump in service and establish a heat sink.
| |
| B. Incorrect, Remaining is FR-H.1 is not correct, a transition to EGA-O.O is required.
| |
| Plausible because other EGAs do not take precedence over the FRGs and with a RED path there is a severe challenge to the Heat Sink function that would be addressed if the TO AFW pump were in service.
| |
| G. GORREGT, The transition to EGA-O.O is the correct action and the reason is because all other procedures, including FR-H. 1, assume a minimum of at least one train of shutdown power is available.
| |
| O. Incorrect, Remaining is FR-H.1 is not correct, a transition to EGA-O.O is required.
| |
| Plausible because power could be restored to the 1B-B board using the maintenance breaker and restoring Heat Sink is critical safety function being challenged.

| 2007 ill NRC Exam ill SRO 100. Given the following plant conditions:
| |
| * The plant is operating at 100% power.
| |
| * EDG "B" is out of service and is expected to return to service in two (2) hours.
| |
| * Subsequently, the following events occur:
| |
| * A loss of offsite power.
| |
| * The reactor is tripped and the crew enters EOP-l.O, Reactor Trip or Safety Injection.
| |
| * 51 is NOT actuated.
| |
| * The crew made a transition to EOP-1S.0, Loss of Secondary Heat Sink, based on a CSFST RED Path.
| |
| * EDG "A" output breaker subsequently trips on a differentia/lockout on Bus 1DA.
| |
| Which ONE (1) of the following describes the actions that will be taken and its bases?
| |
| A. Immediately transition to EOP-6 .0, Loss OfAlI ESF AC Power. All other procedures in the ERG network assume both 7.2 KV ESF busses are available.
| |
| B. Immediately transition to EOP-6 .0, Loss OfAlI ESF AC Power. All other procedures in the ERG network assume a minimum of ONE (1) 7.2 KV ESF bus is available.
| |
| C. Remain in EOP-1S.0 until feed is restored and the RED condition is cleared, and then transition to EOP-6.0 , Loss of All ESF AC Power. RED path Function Recovery procedures must be performed until the condition is cleared.

| SON EOI BASIS DOCUMENT FOR ECA..O.O EPM ..3 ..ECA.. 0.0 PROGRAM LOSS OF ALL AC POWER Rev. 10 MANUAL Page 8 of 98 EOP Step Number: 1 SUSPEND FRP implementation and MONITOR status trees for information only.
| |
| ERG Step Number: 1, Note 2 of 2 CSF Status Trees should be monitored for information only. FRGs should not be implemented.
| |
| | |
| ==Purpose:==
| |
| To inform the operator that this guideline should not be exited to perform any FRP in response to an identified CSF challenge.
| |
| ERG Basis:
| |
| The guideline has priority over all FRGs and is written to implicitly monitor and maintain critical safety functions. This priority is necessary since all FRGs are written on the premise that at least one shutdown board is energized.
| |
| Knowledge:
| |
| Guideline ECA..O.O has priority over the FRGs.
| |
| EOP Basis:
| |
| Same.
| |
| Deviation:
| |
| Converted note into a step.
| |
| Justification:
| |
| Converted note into a step since it contains a hidden action. SON EOP writer's guide disallows hidden actions in cautions and notes. Since the action is required upon entry to ECA..O.O, it is made an immediate action step.
| |
| Setpoint:

| : 90. 076 A2.02 090 Given the following plant conditions:
| |
| Both Units operating at 100% power.
| |
| ERCW system in normal alignment.
| |
| - The following annunciators are LIT on Essential Raw Cooling Water 0-XA-55-27A panel on 1-M-27:
| |
| - "UNIT 1 HEADER A PRESSURE LOW".
| |
| - "UNIT 2 HEADER A PRESSURE LOW".

| - "ERCW DECK SUMP PUMP A RUNNING" is LIT.
| |
| ERCW headers 1A and 2A indicating LOW flow.
| |
| - The crew implements AOP-M.01, "Loss of Essential Raw Cooling Water".
| |
| Which ONE of the following identifies the correct section of AOP-M.01 to be implemented for the conditions and a mitigating action directed to be taken in response to the conditions?
| |
| A. Section 2.7, "Supply Header 1A/2A Failure in the Yard";
| |
| Start additional ERCW pumps to maintain pressure.
| |
| B. Section 2.7, "Supply Header 1A12A Failure in the Yard";

| |
| Page 43
| |
| | |
| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRACTOR ANAL YSIS:
| |
| A. Incorrect, All conditions match entry conditions for Section 2.7 except for sump pump running alarm and the Strainer Dp alarm being lit if the leak were downstream of the strainer. While starting additional pumps might restore pressure,the mitigating action is to stop and lock out the A Train pumps to terminate the leakage for a leak at the location identified by the stem conditions.
| |
| Plausible because Section 2.7 would be the correct procedure section and the starting on additional pumps is a mitigating action during performance of Section
| |
| : 2. 7 for a leak downstream of the strainer.
| |
| B. Incorrect, All conditions match entry conditions for Section 2.7 except for sump pump running alarm and the Strainer Dp alarm being lit if the leak were downstream of the strainer. The A Train pumps being directed to be stopped and locked out is correct for the conditions stated. Plausible because Section 2.7 would be the correct procedure section for a leak downstream of the strainer and the stopping and locking out of the pumps in correct for the leak identified in the stem.
| |
| C. Incorrect, All alarms stated would be lit for a header break upstream of the Strainer. Header pressure sensors are located is located just upstream of the strainers. the sump pump running differentiates the leak upstream from a yard leak (i .e. downstream of the strainer). While starting additional pumps might restore pressure,the mitigating action is to stop and lock out the A Train pumps to terminate the leakage. Plausible because Section 2.9 is the correct procedure section and the starting on additional pumps is a mitigating action for a leak downstream of the strainer (Section 2.7).
| |
| D. CORRECT, All alarms stated would be lit for a header break upstream of the Strainer. Header pressure sensors are located is located just upstream of the strainers. the sump pump running differentiates the leak upstream from a yard leak (i .e. downstream of the strainer). Mitigating action in the AOP section is to stop and lock out all A Train pumps.

| |
| * During operation, CCP and SI Pumps may experience bearing failure 10 minutes after loss of ERCW cooling.
| |
| * Loss of 2A ERCW Supply Header affects both Units' Train A CCS Heat Exchangers. Isolation of ruptured Unit and restoration of ERCW to intact CCS Heat Exchangers is time critical to prevent tripping both Units.
| |
| NOTE:
| |
| * Engineering may be able to identify ruptured yard header using yard piping drawings (17W300 series).
| |
| : 1. DISPATCH personnel to locate failure.

| |
| * Airbome Dose Assessment per SON EPIP-13 "Dose Assessment"
| |
| * ODCM Liquid Release Rate assessment per SON 0-TI-CEM-030.030.0
| |
| * Integrated Airborne Release Rate assessment per SON 0-TI-CEM-030.030.0 (1) The calculated value is outside of the upper range for this detector. The maximum monitor output which can be read is 1.0E+07 cpm. Releases in excess of monitor capacity should be evaluated for proper classification by use of Dose Assessment.
| |
| (2) These unit values are based on flow rates through one PORV of 890,000 Ib/hr at 1078.7 psia with 0.25% carry over (0.9975 quality). Before using these values, ensure a release to the environment is ongoing, (e.g., PORV).
| |
| NOTE 1: These EALs are based on the assumption that an emergency release is restricted to one pathway from the plant. In all cases, the total site EAL is the limiting value. Therefore, in the case where there are multiple release paths from the plant, it is the total release EAL (obtained from ICS and/or SON 0-TI-CEM-030-030, "Manual Calculation of Plant Gas, Iodine, and Particulate Release Rates for Offsite Dose Calculation Manual (ODCM) Compliance") that will determine whether an emergency classification is warranted.
| |
| NOTE 2: In the case when there is no CECC dose assessment available, the length and relative magnitude of the release is the key in determining the classification. For example, in the case of the NOUE EAL of 2 times the Tech Spec limit, the classification is based more on the fact that a release above the limit has continued unabated for more than 60 minutes, than on the projected offsite dose.
| |
| NOTE 3: See REP Appendix B for basis information.

| : 92. 071 A2.05 092 Given the following:
| |
| - A planned release of Waste Gas Tank B is in progress when power is lost to 0-RM-90-118, Waste Gas Effluent Rad Monitor.
| |
| Which ONE of the following identifies (1) the effect the loss of power will have on the release and (2) the requirement to allow any additional release of the tank with the radiation monitor out of service?
| |
| A'! (1) The release will automatically terminate; (2) A new 0-SI-CEM-077-41 0.4, "Waste Gas Decay Tank Release", package would be required for any additional release of the tank after ODCM actions were met.
| |
| B. (1) The release will automatically terminate; (2) The existing 0-SI-CEM-077-41 0.4, "Waste Gas Decay Tank Release",
| |
| package could used for any additional release of the tank after ODCM actions were met.
| |
| C. (1) An alarm will be generated and MANUAL termination of the release will be required; (2) A new 0-SI-CEM-077-41 0.4, "Waste Gas Decay Tank Release", package would be required for any additional release of the tank after ODCM actions were met.
| |
| D. (1) An alarm will be generated and MANUAL termination of the release will be required; (2) The existing 0-SI-CEM-077-41 0.4, "Waste Gas Decay Tank Release",

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRACTOR ANAL YSIS:
| |
| A. CORRECT, the release would be automatically terminated due to an instrument malfunction and a new package would be required to make any additional releases from the tank.
| |
| B. Incorrect, the release would be automatically terminated due to an instrument malfunction but the current SI package would not be used to make any additional releases from the tank, a new package would be required. Plausible because the release would be automatically terminated and releases can be stopped and restarted using the same package under other conditions.
| |
| C. Incorrect, the release would not require manual actions to terminate, it would be automatically terminated due to an instrument malfunction. A new SI package would be required to make any additional releases from the tank. Plausible because some release point radiation monitor instrument malfunctions only alarm and ta new SI isrequiredd for any addition release from the tank.
| |
| D. Incorrect, the release would not require manual actions to terminate, it would be automatically terminated due to an instrument malfunction. The current SI package would not be used to make any additional releases from the tank, a new package would be required. Plausible because some release point radiation monitor instrument malfunctions only alarm and releases can be stopped and restarted using the same package under other conditions.

| |
| Ability to determine and interpret the following as they apply to the Accidental Liquid Radwaste Release:
| |
| Failure modes, their symptoms, and the causes of misleading indications on a radioactive-liquid monitor.
| |
| Question:
| |
| Given the following:
| |
| * The unit is at 100% power and all equipment is available.
| |
| * A planned Cask Decontamination Collector Tank Release is in progress when the following occurs:
| |
| o Annunciator 181-C 'WOS RELEASE LINE 0-RM-90-122 INSTR MALF" alarms.
| |
| o Annunciator 181-A 'WOS RELEASE LINE 0-RM-90-122 L1Q RAO HI" remains dark.
| |
| Which ONE of the following failures would cause the above to prevent an accidental release, and the action required to allow the restart of the release with the radiation monitor out of service?
| |
| A. Loss of power to the rate meter.
| |
| The existing 001 package could be used to resume the release.
| |
| B. Loss of power to the rate meter.
| |
| The existing 001 package closed and new 001 package issued prior to resuming the release.
| |
| C. Loss of signal from the detector.
| |
| The existing 001 package could be used to resume the release.
| |
| O. Loss of signal from the detector.
| |
| The existing 001 package closed and new 001 package issued prior to resuming the release DISTRACTOR ANALYSIS
| |
| : a. Incorrect. The 'loss of power to the rate meter' would generate both the 181 C and 181 A alarms so the 181A alarm would also be LIT. The existing 001 package could not be used to continue the release.
| |
| Plausible because the candidate may not recall the inputs to the alarms correctly and there are conditions identified in the release instructions that do allow the release to be continued using the current 001 package.
| |
| : b. Incorrect. The 'loss of power to the rate meter' would generate both the 181 C and 181 A alarms so the 181A alarm would also be LIT. A new 001 package would be needed to continue the release.
| |
| Plausible because the candidate may not recall the inputs to the alarms correctly, but realize a new 001 package is required to continue the release.
| |
| : c. Incorrect. The 'loss of signal from the detector' would generate a 181-C alarm but would NOT generate a 181 A alarm as stated in the distractor, however the existing 001 package could not be used to continue the release. Plausible because the alarm status listed is correct for the listed condition would cause the termination of the release and the there are conditions identified in the release instructions that do allow the release to be continued using the current 001 package.
| |
| : d. CORRECT. The 'loss of signal from the detector' would generate a 181-C alarm but would NOT generate a 181 A alarm and a new 001 package would be required prior to continuing the release.

| |
| Unit 2 in MODE 6 with the core off-load in progress An internal electrical failure causes the output of Spent Fuel Pit area radiation monitor 0-RM-90-103 to fail above the HI RAD setpoint.
| |
| Which ONE of the following identifies how the Auxiliary Building Isolation (ABI) is affected by the failure and whether the actuation is required to be reported to the NRC in accordance with SPP-3.5, "NRC Reporting Requirements"?
| |
| A. Only Train B is initiated; 8-hour notification required.

| D. Both Train A & Train B are initiated; 8-hour notification NOT required.
| |
| DISTRACTOR ANAL YSIS:
| |
| A. Incorrect, Only the Train B ABI will be initiated from the monitor but no 8-hour notification would be required because the actuation would be an invalid actuation. Plausible because the initiation of Train B only is correct and ESF actuations are normally reportable.
| |
| B. CORRECT, Only the Train B ABI will be initiated from the monitor and actuation would be an invalid actuation, thus,no 8-hour notification would be required.
| |
| C. Incorrect, Both'trains will not be initiated, only the Train B will initiate and no 8-hour notification would be required because the actuation would be an invalid actuation.
| |
| Plausible because other actuations do come from multiple sensors through isolation/separation relays and ESF actuations are normally reportable.
| |
| D. Incorrect, Both trains will not be initiated, only the Train B will initiate and no 8-hour notification would be required because the actuation would be an invalid actuation.
| |
| Plausible because other actuations do come from multiple sensors through isolation/separation relays and the actuation not being reportable is correct.

| paragraphs as well as under 10 CFR 50.72(b){3)(v) and 10 CFR 50.73(a)(2)(v) (event or condition that could have prevented the fulfillment of the safety function of .... ).
| |
| With regard to preplanned actuations, operation of a system as part of a planned test or operational evolution need not be reported. Preplanned actuations are those which are expected to actually occur due to preplanned activities covered by procedures. Such actuations are those for which a procedural step or other appropriate documentation indicates the specific actuation is actually expected to occur. Control room personnel are aware of the specific signal generation before its occurrence or indication in the control room. However, if during the test or evolution, the system actuates in a way that is not part of the planned evolution, that actuation should be reported. For example, if the normal reactor shutdown procedure requires that the control rods be inserted by a manual reactor scram, the reactor scram need not be reported.
| |
| However, if unanticipated conditions develop during the shutdown that cause an automatic reactor scram, such a reactor scram should be reported. The fact that the safety analysis assumes that a system will actuate automatically during an event does not eliminate the need to report that actuation. Actuations that need not be reported are those initiated for reasons other than to mitigate the consequences of an event (e.g., at the discretion of the licensee as part of a planned evolution).
| |
| Note that if an operator were to manually scram the reactor in anticipation of receiving an automatic reactor scram, this would be reportable just as the automatic scram would be reportable.
| |
| Valid ESF-actuations are those actuations that result from "valid signals" or from intentional manual initiation, unless it is part of a preplanned test. Valid signals are those signals that are initiated in response to actual plant conditions or parameters satisfying the requirements for initiation of the safety function of the system. Note tRis definition of "'Velid" refjuires tRet the initietion signel must be en [SF signel. TRis distinction eliminetes ectuetions They do not include those which are the result of other signals from tRe elessof velid ectuetions. Invalid actuations are, by definition, those that do not meet the criteria for being valid. Thus, invalid actuations include actuations that are not the result of valid signals and are not intentional manual actuations.
| |
| Except for critical scrams, invalid actuations are not reportable by telephone under § 50.72. In addition. invalid actuations are not reportable under § 50.73 in any of the following circumstances:
| |
| (A) The invalid actuation occurred when the system is already properly removed from service.
| |
| This means all requirements of plant procedures for removing equipment from service have been met. It includes required clearance documentation, equipment and control board tagging, and properly positioned valves and power supply breakers.
| |
| (8) The invalid actuation occurred after the safety function has already been completed. An example would be RPS actuation after the control rods have already been inserted into the core.
| |
| If an invalid ESF-actuation reveals a defect in the ESF-system so the system failed or would fail to perform its intended function,the event continues to be reportable under other requirements of 10 CFR 50.72 and 50.73. When invalid tsF-actuations excluded by the conditions described 49 NUREG-1022, Rev. 2

An ISFSI which is located on the site of another facility licensed under §Part 72 or a facility licensed under §Part 50 (e.g., an operating nuclear power plant) and which shares common utilities and services with that facility or is physically connected with that other facility may still be considered independent.
| |
| Initiation of Shutdown - Physical act of reducing power or temperature to change modes.
| |
| Invalid Actuation (Signal) - Signals that do not meet the criteria for being valid. Invalid actuations include instances where instrument drift, spurious signals, human error or other invalid signals that result in manual or automatic actuation of the systems listed in
| |
| §50.73(a)(2)(iv)(8).
| |
| Major Loss of Communication - Constitutes the loss of communication capabilities.
| |
| Major Deficiency - A condition or circumstance which under normal operating conditions, an anticipated transient, or postulated design basis accident could contribute to exceeding a safety limit or cause an accident. "Major deficiency" also means a condition or circumstance which in the event of an accident due to other causes could, considering an independent single failure, result in a loss of safety function necessary to mitigate the consequences of the accident.
| |
| Natural Phenomenon - Act of nature (e.g., fire, flood, tornado).
| |
| News Release - Known items which may be distributed to the media (UPI, television, radio, newspaper, etc.) and those items identified to be going on TVA news tape distributed by the TVA Public Affairs Staff.
| |
| Noncompliance (Failure To Comply) - A noncompliance for the purposes of this procedure means any failure to comply with the Atomic Energy Act of 1954, as amended, or with any applicable rule or regulation of the NRC relating to sUbstantial safety hazards.
| |
| A noncompliance may be in operations, engineering, or construction of the facility or basic component thereof.
| |
| Organization Manager - This is the most senior manager available who is in the same organization as the individual who discovered the abnormal event. The senior manager is not normally interpreted to be the plant manager or site vice president.
| |
| Preplanned Sequence - Part of an approved procedure, including workplans, work request, work orders, surveillance instructions, general operating instructions and system operating instructions.
| |
| Prevented The Fulfillment - Failure or possible failure of a safety system to properly complete a safety function.
| |
| | |
| NPG Standard Regulatory Reporting Requirements SPP-3.5 Programs and Rev. 0020 Processes Page 15 of 64 5.0 DEFINITIONS (continued)
| |
| Principal Safety Barrier - Fuel cladding, RCS pressure boundary, or the containment.
| |
| Redundant Equipment - Equipment, systems, structures capable of performing the same intended function within the same Technical Specification allowable values. (In most cases, this means opposite train equipment.)
| |
| Safe Shutdown - Mode 3, as defined by the Technical Specifications.

| |
| * A major deficiency in design, construction, or operation having potential generic safety implications,
| |
| * A significant loss of integrity of the fuel, the primary coolant boundary, or the primary containment boundary,
| |
| * A loss of safety function or multiple failures in systems used to mitigate an actual event,
| |
| * Significant unexpected system interactions,
| |
| * Repetitive failures or events involving safety related equipment or deficiencies in operation,
| |
| * Questions or concerns pertaining to licensee operational performance.
| |
| Substantial Safety Hazard - Loss of safety function to the extent that there is a major reduction in the degree of protection provided to public health and safety for any facility or activity licensed.
| |
| Threat - Physical hazard (e.g., fire, severe radioactive release).
| |
| Unanalyzed Condition - Plant Condition outside the bounds of the initial conditions as described in the FSAR accident analysis.
| |
| Valid Actuation (Signal) - Valid actuations are those that result from "valid signals" or from intentional manual initiation. Valid signals are those that are initiated in response to actual plant conditions or parameters satisfying the requirements for initiation of the safety function of the system.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA CTOR ANAL YSIS:
| |
| A. Incorrect, BA T A volume of 9600 gallons at 6500 ppm with an RWST boron concentration of 2575 ppm is in the unacceptable region of TRM Figure 3.1.2.6 for BA T Tank Limits. Near the of life peak xenon is when the maximum expected boration capability requirement occurs as identified in Technical Requirement bases. Plausible because the BA T volume, BA T boron concentration, and the RWST boron concentration are near the limit and require interpolation when using the graph. Also, the higher level in the tank is not the correct answer and the limiting conditions occurring at near EOL is correct.
| |
| B. Incorrect, BA T A volume of 9600 gallons at 6500 ppm with an RWST boron concentration of 2575 ppm is in the unacceptable region of TRM Figure 3.1.2.6 for BAT Tank Limits, and the Beginning of life peak xenon is not when the maximum expected boration capability requirement occurs. Technical Requirement bases identifies the requirement to be at near EOL with peak Xenon conditions. Plausible because the BA T volume, BA T boron concentration, and the RWST boron concentration are near the limit and require interpolation when using the graph. Also, the higher level in the tank is not the correct answer and for other circumstances the limiting conditions occur at the beginning of life.
| |
| C. CORRECT, BA T A volume of 9200 gallons at 6775 ppm with an RWST boron concentration of 2575 ppm is in the acceptable region of TRM Figure 3.1.2.6 for BAT Tank Limits and the bases for the Technical Requirement states that the maximum expected boration capability requirement occurs at near EOL with peak Xenon conditions.
| |
| D. Incorrect, BA T A volume of 9200 gallons at 6775 ppm with an RWST boron concentration of 2575 ppm is in the acceptable region of TRM Figure 3.1.2.6 for BAT Tank Limits, but the Beginning of life peak xenon is not when the maximum expected boration capability requirement occurs. Technical Requirement bases identifies the requirement to be at near EOL with peak Xenon conditions. Plausible because the combination of BA T volume and boron concentration place the tank in an acceptable region of the graph and other limiting conditions to occur at the beginning of life.

| REACTIVITY CONTROL SYSTEMS
| |
| ') BASES TRB 3/4.1.2 BORATION SYSTEMS The boron injection system ensures that negative reactivity control is available during each mode of facility operation. The components required to perform this function include 1) borated water sources,
| |
| : 2) charging pumps, 3) separate flow paths, 4) boric acid transfer pumps, and 5) an emergency power supply from OPERABLE diesel generators.
| |
| With the RCS average temperature above 350°F, a minimum of two boron injection flow paths are required to ensure single functional capability in the event an assumed failure renders one of the flow paths inoperable. The boration capability of either flow path is sufficient to provide a SHUTDOWN MARGIN from expected operating conditions of 1.6% delta klk after xenon decay and cooldown to 200°F. The maximum expected boration capability requirement occurs at near EOl from full power peak xenon conditions and requires borated water from a boric acid tank in accordance with Figure 3.1.2.6, and additional makeup from either: (1) the common boric acid tank and/or batching, or (2) a minimum of 26,000 gallons of 2500 ppm borated water from the refueling water storage tank. With the refueling water storage tank as the only borated water source, a minimum of 57,000 gallons of 2500 ppm borated water is required.
| |
| The boric acid tanks, pumps, valves, and piping contairi a boric acid solution concentration of between 3.5% and 4.0% by weight. To ensure that the boric acid remains in solution, the air temperature is monitored in strategic locations. By ensuring the air temperature remains at 63°F or above, a 5°F margin is provided to ensure the boron will not precipitate out. To provide operational flexibility, if the area temperature should fall below the required value, the solution temperature (as determined by the
| |
| ) pipe or tank wall temperature) will be monitored at an increased frequency to compensate for the lack of solution temperature alarm in the main control room.
| |
| With the ReS temperature below 350°F, one injection system is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and operations involving positive reactivity additions that could result in loss of required SDM (Modes 40r 5) or boron concentration (Mode 6) in the event the single injection system becomes inoperable. Suspending positive reactivity additions that could result in failure to meet minimum SDM or boron concentration limit is required to assure continued safe operation. Introduction of coolant inventory must be from sources that haVe a boron concentration greater than or equal to that required in the RCS for minimum SDM or refueling boron concentration. This may result in an overall reduction in RCS boron concentration but provides acceptable margin to maintaining subcritical operation. Introduction of temperature changes including temperature increases when operating with a positive MTC must also be evaluated to ensure they do not result in a loss of required SDM.
| |
| The boron capability required below 350°F, is suffiCient to provide a SHUTDOWN MARGIN of 1.6% delta klk after xenon decayand cool down from 350"F to 200°, and a SHUTDOWN MARGIN of 1%
| |
| delta klk after xenon decay andcooldown from 200°F to 140°F. This condition requires either 6400 gallons of 6120 ppm borated water from the boric acid storage tanks or 13,400 gallons of 2500 ppm borated water from the refueling water storage tank.

| |
| - During the Operations review of a Work Orde~O), the SRO determines the return to operability (RTO) Post Maintenance Test (PMT) needs revision.
| |
| - The WO did not require an Independent Qualified Review (IQR), a 10CFR50.59 review, or 10CFR72.48 review.
| |
| In addition to documenting the reason for the revision, which ONE of the following identifies both ...
| |
| (1) the requirement to revise the RTO test without routing the WO back through the review process and (2) when this type PMT revision would require Shift Manager approval?
| |
| A'! (1) Revision signed by 2 SROs.
| |

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRACTOR ANAL YSIS:
| |
| A. CORRECT, SPP-6.3 allows revisions to RTO tests to be made by 2 SROs without routing back through the review cycle for the conditions identified in the stem of the question and does require Shift Manager approval if a generation critical component is involved.
| |
| B. Incorrect, SPP-6.3 allows revisions to RTO tests to be made by 2 SROs without routing back through the review cycle for the conditions identified in the stem of the question but does not require Shift Manager approval because a configuration change on the unit would be involved. Plausible because 2 SRO being required to make the revision is correct and verification of configuration changes are identified in the SPP as needing independent verification.
| |
| C. Incorrect, SPP-6.3 allows revisions to RTO tests to be made by 2 SROs, not an SRO and the Work Week Manager but Shift Manager approval if a generation critical component is involved is correct. Plausible because the Work Week Manager has other functions and requiring Shift Manager approval if a generation critical component is involved is correct.
| |
| D. Incorrect, SPP-6.3 allows revisions to RTO tests to be made by 2 SROs, not an SRO and the Work Week Manager and Shift Manager approval because a configuration change on the unit would be involved is also not correct. Plausible because the Work Week Manager has other functions and verification of configuration changes are identified in the SPP as needing independent verification.

| |
| B. Incorrect, IQR review for minor editorial changes for Quality Related procedures is required and SPP-2.2 allows for the SRO on the Unit being the approval authority. Plausible because the IQR review is required for minor/editorial changes to quality related procedures and the SRO on the unit is not the approval authority for normal procedure revisions.
| |
| C. Incorrect, SPP-2.2 requires IQR review for minor editorial changes for Quality Related procedures and allows for the SRO on the Unit being the approval authority. Plausible because the IQR review is not required for minor/editorial changes to non-quality related procedures and the SPP allows for the SRO on the unit being the approval authority.
| |
| D. Incorrect, IQR review for minor editorial changes for Quality Related procedures is required and allows for the SRO on the Unit being the approval authority.

| |
| S. Due to relative air pressure differences between the Containment and Auxiliary Buildings which causes excessive air flow through the transfer tube, if the Transfer Tube Wafer Valve 1,2-78-610 is open, at least one of four conditions should exist to minimize the potential spread of airborne contamination: Reference TS 3.9.4.
| |
| : 1. The Containment equipment hatch stays open. This is not permitted during movement of recently irradiated fuel within containment (less than 100 hours since shutdown).
| |
| : 2. A Containment airlock is breached open (both doors) (not permitted during fuel movement within the containment unless one train of ABGTS is operable and one door of each breach airlock is capable of closure).
| |
| : 3. The lower reactor cavity has water filled to a level above the transfer tube elevation.
| |
| : 4. Containment ventilation purge supply/exhaust are stopped and measured differential pressure is approximately 0.25 psid or less between Computer Points P1001A to P1002A.
| |
| T. The use of the 1 ton Jib Crane in Unit One Containment is limited to Modes 6 and defueled conditions. The 1 ton Jib Crane will not be used during fuel handling operations or when there is the potential for interference with other cranes operation in the vicinity.
| |
| 3.2 LIMITATIONS A. Do not allow reactor vessel head to come into contact with the refueling water.
| |

| |
| A. Incorrect, The 690 pipe chase on both units is not a Very High Radiation Area (VHRA) but a key being located in the MCR under the administrative control of the Shift Manager is correct. Plausible because VHRA do exist and the Shift Manager does have access to a key located in the MCR.
| |
| B. Incorrect, The 690 pipe chase on both units is not a Very High Radiation Area (VHRA) and Rad Ops does not have not only key. Plausible because if the area had been a VHRA then only Rad Ops would have a key.
| |
| C. CORRECT, The 690 pipe chase on both units is a Locked High Radiation Area (LHRA). RCI-29 identifies the area as such and designates 2 key locations. One in the Rad Ops Lab and the other in the MCR under the administrative control of the Shift Manager.
| |
| D. Incorrect, The 690 pipe chase on both units is a Locked High Radiation Area (LHRA). Rad Ops is not the only location of a key. Another key is located in the MCR under the administrative control of the Shift Manager. Plausible because if the area is a locked high radiation area and for all other LHRA only Rad Ops has a key.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRA CTOR ANAL YSIS:
| |
| A. CORRECT, with the fire a the ERCW pumping station still burning and the staffing at minimum (8 AVOs), all AVOs will report to the main control room because in accordance with AOP-N.01, the requirement to assemble AVOs to assign and brief the actions of AOP-N.08 take priority over staffing the OSC and Level II Fire Brigade. Separate entry into AOP-N.08 is allowed in accordance with AOP-N.01 because the criteria requiring both units to enter the AOP at the same time are not met. The fire is not in one of the four limiting areas that require simultaneous entry by both units ..
| |
| B. Incorrect, with the fire a the ERCW pumping station still burning and the staffing at minimum (8 AVOs), all AVOs will report to the main control room because in accordance with AOP-N.01, the requirement to assemble AVOs to assign and brief the actions of AOP-N.08 take priority over staffing the OSC and Level II Fire Brigade. However the AOP-N.08 entry does not met the criteria requiring both units to enter at the same time. Plausible because the directions to the AVOs is correct and a fire in a different location could cause the units to enter the AOP at the same time.
| |
| C. Incorrect, with the fire a the ERCW pumping station still burning and the staffing at minimum (8 AVOs), 2 AVOs would not be sent to the OSC, all would report to the main control room in accordance with AOP-N.01 because the requirement to assemble A VOs to assign and brief the actions of A OP-N. 08 takes priority over staffing the OSC and Level II Fire Brigade. The AOP-N.08 can be made separately because entry does not met the criteria requiring both units to enter at the same time. Plausible because the directions to send 2 AVOs to the OSC is the normal protocol during an emergency event and the units entry into the AOP being allowed at separate times in correct.
| |
| D. Incorrect, with the fire a the ERCW pumping station still burning and the staffing at minimum (8 AVOs), 2 AVOs would not be sent to the OSC, all would report to the main control room in accordance with AOP-N.01 because the requirement to assemble AVOs to assign and brief the actions of AOP-N.08 takes priority over staffing the OSC and Level II Fire Brigade. Also, the AOP-N.08 entry does not met the criteria requiring both units to enter at the same time. Plausible because the directions to send 2 AVOs to the OSC is the normal protocol during an emergency event and a fire in a different location could cause the units to enter the AOP at the same time.

| |
| : 2. Operations Personnel
| |
| : a. The protocol requires two AUOs to go to the OSC and the remaining AUOs go to the Main Control Room. The SM may send the AUOs to a waiting area within the protected ventilation area of the Control Building (such as the SM Office) if noise or congestion become a problem in the MCR.
| |
| : b. When the OSC Ops Advisor arrives in the OSC, he and the SM will collectively manage the resources to have the fastest response to problems yet still provide a check of radiological conditions prior to I Obj S.b dispatching an AUO. Dispatching AUOs into plant areas needs input by RP as to appropriate protective equipment. This is best done by the OSC Ops Advisor once he/she arrives. The OSC Ops Advisor is expected to relieve the SM of some of the administrative burden of tracking field personnel so he/she can focus on the higher priority of operational safety.
| |
| : c. The Shutdown Board Rooms and Control Building are spaces with protected ventilation similar to the MCR. Until advised by RP that these areas are becoming unsafe, they should be considered part of the MCR for the purpose of dispatching AUOs. This means that AUOs may be dispatched into these areas for tasks without being considered a "team" (much like sending an AUO behind the panels in the MCR to perform a task). As always, communications must be maintained at all times with AUOs while out on assignments and the TSC should be informed of AUO activities.
| |
| : d. This protocol allows dispatching AUOs by telephone briefing and/or radio briefing as well as transfer of oversight of individual AUOs between the OSC SRO and SM as needed. This provides the best utilization of personnel while still protecting the AUOs from radiological hazards.
| |
| : e. AUOs assigned to the OSC will report directly to the OSC when required.
| |
| : f. The SM is responsible to account for MCR personnel.

| |
| Both units trip from power operation due a loss of off site power and sabotage is suspected.
| |
| Nuclear Security reports the following:
| |
| - Information has been received that a specific credible insider threat exists associated with the loss of offsite power.
| |
| and
| |
| - Concerns exist for the health and safety of any oncoming emergency responders.

| Proposed 2/6/2009 Sequoyah NRC SRO Written Exam as submitted DIS TRACTOR ANAL YSIS:
| |
| A. Incorrect, In accordance with the Emergency Plan, if concerns exist for the health and safety of oncoming responders, the "Staging Area" choice is to be selected when initiating the staffing of the Emergency Centers but when the two-man rule is implemented, the individuals do not have to have the same qualifications. Plausible because choosing the "Staging Area" when initiating the staffing of the Emergency Centers is correct and typically when personnel are sent to perform a task both would be qualified.
| |
| B. CORRECT, In accordance with the Emergency Plan, if concerns exist for the health and safety of oncoming responders, the "Staging Area" choice is to be selected when initiating the staffing of the Emergency Centers and the individual do not have to posses the same qualification when the two-man rule is implemented.
| |
| C. Incorrect, the "Staging Area" choice is to be selected when initiating the staffing of the Emergency Centers (not the the "Emergency''), when concerns exist for the health and safety of oncoming responders, and the individual do not have to posses the same qualification when the two-man rule is implemented. Plausible because the the "Emergency" choice would be correct with different conditions when inititiating the staffing of the Emergency Centers and typically when personnel are sent to perform a task both would be qualified.
| |
| D. Incorrect, the "Staging Area" choice is to be selected when initiating the staffing of the Emergency Centers (not the the "Emergency''), when concerns exist for the health and safety of oncoming responders, and the individual do not have to posses the same qualification when the two-man rule is implemented. Plausible because the the "Emergency" choice would be correct with different conditions when inititiating the staffing of the Emergency Centers and the requirement for only one of the individuals to be qualified is correct.
