| |
| B. More than one but less than four SRVs will open.
| |
| NO SVs will open.
| |
| C. Four SRVs will open.
| |
| NO SVs will open.
| |
| D. Four SRVs will open.
| |
| Two SVs will open.
| |
| Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect - With Reactor pressure at 1153 psig, this is above the set pressure of all four valves and all the valves will correspondingly open.
| |
| B. Incorrect - With Reactor pressure at 1153 psig, this is above the set pressure of all four valves and all the valves will correspondingly open.
| |
| | |
| C. Correct - The safety/relief valves are self actuating Target Rock Relief Valves set between 1095 and 1115 +/- 11 psig per T.S. and have a capacity of 862,125 Ibm/hr each at a reference pressure of 1080 psig. Each SRV is sized to relieve 10% of the main steam system flow. With Reactor pressure at 1153 psig, this is above the set pressure of all four valves and all the valves will correspondingly open.
| |
| The two self-actuating safety valves lift at 1240 +/- 13 psig. The valves open when sufficient reactor pressure forces the valve upward against spring pressure. Spring pressure (and thus the lift setpoint) can be adjusted by a compression screw at the safety valve top. Because Reactor pressure has not reached 1240 psig the SVs will remain closed.
| |
| D. Incorrect - The two self-actuating safety valves lift at '1240 +/- 13 psig. The valves open when sufficient reactor pressure forces the valve upward against spring pressure.
| |
| Spring pressure (and thus the lift setpoint) can be adjusted by a compression screw at the safety valve top. Because Reactor pressure has not reached 1240 psig the SVs will remain closed.

| |
| * Reactor pressure is steady at 880 psig
| |
| * The HPCI Controller is in AUTO Then the flow signal to the HPCI controller fails to zero.
| |
| Which one of the following describes how Reactor pressure and HPCI flow are affected by this failure?
| |
| Reactor Pressure Actual HPCI Flow A. Rises Rises B. Rises Lowers C. Lowers Rises D. Lowers Lowers Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect - Because reactor pressure would lower due to the increased steam demand.
| |
| B. Incorrect - Because reactor pressure would lower due to the increased steam demand and HPCI flow would rise as the controller attempted to increase flow.
| |
| C. Correct - In AUTO or BAL, flow demand signal, as determined by the FIC set point tape, controls turbine speed. The speed control circuit has a 0-4000 rpm range with the lowest flow corresponding to 2000 rpm. With the controller in AUTO (system operating to maintain the selected flowrate), a reduction in reactor pressure will result in HPCI's
| |
| | |
| control valve closing down to maintain the flow rate constant.
| |
| A loss of HPCI flow signal will result in the speed controller raising the output signal.
| |
| This causes the HPCI turbine speed/flow to rise. HPCI will remain in operation at a higher actual flow than before the failure. The effect of the increased HPCI load will be a greater steam demand on the reactor lowering reactor pressure.
| |
| D. Incorrect - Because HPCI flow would rise due to the controller attempting to raise flow.

| |
| * The plant is maneuvering to cold shutdown following an extended high power run
| |
| * Reactor pressure is 10 psig and steady
| |
| * The MSIVs are closed
| |
| * "A" RHR pump is in shutdown cooling in accordance with PNPS 2.2.19.1, RESIDUAL HEAT REMOVAL SYSTEM - SHUTDOWN COOLING MODE OF OPERATION Which of the following malfunctions will result in a rise in reactor pressure? Assume no operator action.
| |
| Malfunction 1: MO-1001-16A, RHR HX A BYP VLV, fails full open.
| |
| Malfunction 2: Loss of all 125 VDC electrical power to the Group 3 Isolation Logic.
| |
| Malfunction 3: Loss of 120 VAC Safeguard bus Y-3.
| |
| A. Malfunction 1 only B. Malfunction 3 only C. Malfunctions 2 and 3 only D. Malfunctions 1 and 2 only Proposed Answer: A Explanation (Optional):
| |
| A. Correct: MO-1001-16A, is the heat exchanger bypass valve. This valve failing open will cause a portion of the RHR flow to bypass the heat exchanger reducing the heat removed from the vessel, causing reactor pressure to rise.
| |
| B. Incorrect: PDC94-24, Shutdown Cooling Logic Improvements, changed the power supply to the PCIS logic for Group 3 SDC isolations from 120V AC (Y3/y4) to 125V DC
| |
| | |
| (D4/D5). These relays were changed from "DE-ENERGIZE TO OPERATE" to "ENERGIZE TO OPERATE", which means on a loss of D4 and/or D5, the MO-1001-47 and MO-1001-50 SDC Isolation Valves will not close.
| |
| C. Incorrect: PDC94-24, Shutdown Cooling Logic Improvements, changed the power supply to the PCIS logic for Group 3 SDC isolations from 120V AC (Y31Y4) to 125V DC (D4/D5). These relays were changed from "DE-ENERGIZE TO OPERATE" to "ENERGIZE TO OPERATE", which means on a loss of D4 and/or D5, the MO-1001-47 and MO-1001-50 SDC Isolation Valves will not close.
| |
| Additionally, a loss of Y-3 will not cause SDC to isolate. Plausible in that it will cause the inboard isolation valves to close for Group 2 and Group 6 isolations and RBIS.
| |
| D. Incorrect: A loss of Y-3 will not cause SDC to isolate. Plausible in that it will cause the inboard isolation valves to close for Group 2 and Group 6 isolations and RBIS.

| |
| Proposed Answer: 0 Explanation (Optional):
| |
| A. Incorrect: The System will initiate as soon as the button is depressed. Pushing the button simulates a low-low water level signal.
| |
| B. Incorrect - RCIC will start RCIC in the full flow injection mode when the switch is depressed.
| |

| |
| * A loss of Turbine Building Closed Cooling Water (TBCCW) occurs
| |
| * The Instrument Air Compressors (lACs) are operating in parallel control mode Which of the following describes the lACs response with no operator action?
| |
| A. The K11 0 and K111 lACs trip on high discharge temperature, the K117 lAC starts and restores Instrument Air pressure.
| |
| B. The K11 0 and K111 lACs trip on low cooling water flow interlock, the K117 lAC starts and restores Instrument Air pressure.
| |
| C. The K111 and K117 lACs trip on low cooling water flow interlock, the K11 0 lAC trips on high discharge temperature.
| |
| D. The K11 0 and K111 lACs trip on high discharge temperature, the K117 lAC trips on high oil temperature, or high intercooler temperature.
| |
| Proposed Answer: A Explanation (Optional):
| |
| A. Correct - With the lACs operating in parallel a trip of either lead compressor (110 or 111) will result in the other compressor (111 or 110) assuming the load. Both these compressors will trip on high discharge temperature with a loss of TBCCW. AS pressure lowers further lAC 117 the Diesel Air Compressor will start. lAC 117 does not use TSCCW for cooling water so it will auto start and restore IA pressure.
| |
| B. Incorrect - K11 0 and K111 lACs trip on high discharge temperature, these compressors do NOT have a trip on low TBCCW flow to the compressor.
| |
| | |
| C. Incorrect - lAC 117 the Diesel Air Compressor will start. lAC 117 does not use TBCCW for cooling water so it will continue to operate and maintain IA pressure. K111 trips on high discharge temperature, this compressor does NOT have a trip on low TBCCW flow to the compressor.
| |
| D. Incorrect - lAC 117 the Diesel Air Compressor will start. lAC 117 does not use TBCCW for cooling water so it will continue to operate and maintain IA pressure. Plausible in that the K-117 will trip on high oil temperature, or high intercooler temperature if either of these two conditions were to occur.

| A. Incorrect - Without the instrument air system the leve! indicator will fail downscale, no dip to measure.
| |
| B. Incorrect - The loss of instrument air fails the SLC tank level instrument downscale since this provides the indication for the low level trip of the SLC tank heater the heater also fails.
| |
| C. Correct - Instrument air supplies the air for the bubbler dip tube, which is associated with the storage tank level transmitters. Loss of instrument air will cause the local and control room level indicators to fail low. Also the level switch for the heaters will be actuated causing a loss of tank heaters in automatic or in manual control.

| |
| A. Incorrect: These pumps will not be available because bus A1 will de-energize when the turbine trips due to the loss of associated breaker control power. Plausible in that this would be the response if D-17 were lost.
| |
| | |
| B. Correct: Normally when the turbine trips, A 1, A3, and A5 transfer to the startup transformer. However the breakers associated with the transfer will be without control power. Therefore when the turbine trips, A1, A3, and A5 will be de-energized and associated loads will be lost. Bus A 1 supplies "A" and "C" feed pumps and "B" condensate pump. The only remaining pumps will be "B" feed pump and "A" and "C" condensate pumps. The buses associated with these pumps are supplied with control power from the "B" battery (0-17).
| |
| C. Incorrect: "B" feed pump and "A" and "C" condensate pumps would be running.
| |
| Plausible if the candidate thinks that 0-16 supplies control power to bus A2. If so the candidate may also believe that when the other two condensate pumps are de energized, that two reactor feed pumps will also trip on interlock. This is not true as the breakers associated with the condensate pumps do not trip as there is no control power.

| |
| * A LOCA is in progress
| |
| * Drywell pressure is 18 pSig
| |
| * RHR Pumps A and C are injecting into the RPV
| |
| * RHR Pump 8 is in containment spray mode
| |
| * RHR Loop Cross-Tie Valve, MO-1001-19, has been closed
| |
| * RHR Pump D has been manually shutdown and its white override light is illuminated.
| |
| Two minutes later, a loss of offsite power occurs, de-energizing both the Startup and the Shutdown Transformers.
| |
| * "An EDG output breaker fails to close
| |
| * "8" EDG output breaker closes and the diesel loads as designed Which one of the following identifies the RHR pump status after power is restored from the EDG?
| |
| A. RHR Pump 8 is running in the injection mode. RHR pump D is not running.
| |
| B. RHR Pumps Band D are running in the containment spray mode only.
| |
| C. RHR Pump B is running in both the injection and containment spray modes. RHR pump D is not running.
| |
| D. RHR Pumps Band D are running in both the injection and containment spray modes Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect - The B EDG re-energizes A6 after a time delay. The "B" RHR pump will start
| |
| | |
| 5 seconds after the bus is re-energized. The "0" RHR pump will start 10 seconds after the bus is re-energized. Although the pump was manually shutdown the bus power monitoring circuit will defeat the operator's manual over ride and the pump restarts.
| |
| : 8. Correct - The white light will illuminate and remain lit if the operator manually shuts down an RHR pump with an auto start signal present (LPCI initiation signal). When offsite power is lost the operating RHR pumps will trip. The 8 EDG re-energizes A6 after a time delay. The "8" RHR pump will start 5 seconds after the bus is re-energized.
| |
| The "0" RHR pump will start 10 seconds after the bus is re-energized. Although the pump was manually shutdown the bus power monitoring circuit will defeat the operator's manual over ride and the pump restarts. Loop select initially selected loop A for injection and was sealed in. It will not re-initiate because the logic never lost power (DC power). 8ecause the containment spray valves remain open RHR Pumps 8 and o will operate in Containment Spray. There are no auto opening signals for the Cross Tie valve.
| |
| C. Incorrect - The 8 EDG re-energizes A6 after a time delay. The "8" RHR pump will start 5 seconds after the bus is re-energized. The "0" RHR pump will start 10 seconds after the bus is re-energized.
| |
| D. Incorrect - The LPClioop selection logic is DC powered and therefore it never lost power. Since it selected the "A" loop initially and seals in, loop "A" is still selected for injection and the "8" loop injection valves do not open. With the Cross-Tie closed and the containment spray valves open the 8 and 0 Pumps will operate in Containment Spray only (There are no auto opening signals for the Cross-Tie valve.)

| |
| * The plant is at rated conditions
| |
| * 'A' Fuel Pool Cooling Heat Exchanger was placed in service 5 minutes ago
| |
| * The BOP operator reports that RBCCW Loop 'A' temperature has risen from 70 degrees to 82 degrees.
| |
| * 'A' and "B' RBCCW pumps are in service.
| |
| * Indications on TIC - 3836, RBCCW Loop 'A' Temperature Controller are as shown in the drawing below.
| |
| Which one of the following is correct regarding the controller operation and what actions are required to restore RBCCW temperature to normal?
| |
| TIC-3836 0.0 WP RL AM A. The controller has NOT responded correctly to the increase in heat load. Place the controller in manual and increase the controller output.
| |
| | |
| B. The controller has NOT responded correctly to the increase in heat load. Manually close MO-4084, Loop 'A' RBCCW Heat Exchanger Bypass Valve, to increase RBCCW flow through the heat exchanger.
| |
| C. The controller IS responding correctly to the increase in heat load. Jog open MO-3800
| |
| 'A' RBCCW Heat Exchanger SSW Outlet Valve to increase SSW flow.
| |
| D. The controller IS responding correctly to the increase in heat load. Start the third RBCCW pump and increase RBCCW flow through the heat exchanger to 5000 gpm.
| |
| Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect: The controller is responding as expected to temperature being higher than the setpoint (70 degrees). The controller controls the position of a bypass valve. As temperature comes up the controller lowers the output which will close down on the bypass valve forcing more RBCCW flow thru the heat exchanger. Plausible in that the output of the controller is zero.
| |
| B. Incorrect: The controller is responding as expected to temperature being higher than the setpoint (70 degrees). The controller controls the position of a bypass valve. As temperature comes up the controller lowers the output which will close down on the bypass valve forcing more RBCCW flow thru the heat exchanger. Plausible in that the output of the controller is zero.
| |
| C. Correct: As discussed above the controller is responding normally. Additional SSW flow is required to lower the RBCCW temperature. Per PNPS 2.2.32 SSW, MO-3800 'N RBCCW Heat Exchanger SSW Outlet Valve is adjusted as required based on plant conditions to control temperature.
| |

| Proposed Question: RO Question # 19 Given the following:
| |
| * The plant is at 30% power with a normal electrical distribution lineup;
| |
| * 480 VAC Load Center B-6 is lost when the supply breaker on B-1, B52-102, trips due to a breaker fault;
| |
| * Operators report the following indications regarding 120 VAC Vital Bus Y-2:
| |
| o Alarm Y-2 AUTOMATIC TRANSFER, C3RC-A2, has annunciated o The Y-2 potential indicating light on C3 extinguished briefly but is now lit.
| |
| Operators have stabilized the plant and are now making preparations to re-energize B6 from 480 VAC Load Center B-2.
| |
| Based on the above information which one of the following is correct regarding (1) The initial response of Y-2 to the transient AND (2) Any automatic response of Y-2 when B-6 is re-energized?
| |
| A. (1) Y-2 responded as designed (2) Y-2 will remain on its alternate power supply, B-15 B. (1) Y-2 did NOT respond as designed (2) Y-2 will remain on its alternate power supply, B-15 C. (1) Y-2 responded as designed (2) Y-2 will automatically transfer back to its preferred power supply, the Y-2 MG Set D. (1) Y-2 did NOT respond as designed (2) Y-2 will automatically transfer back to its preferred power supply, the Y-2 MG Set
| |
| | |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect: Y-2 is normally powered from a MG set that has both a DC and AC driver.
| |
| The AC driver, powered from B-6 is normally powering the MG set. If B-6 power is lost, the DC motor will then power the MG set. A large flywheel on the MG maintains Y-2 voltage and frequency as the drivers shift from AC to DC. If the MG set fails or DC power is not available and Y-2 de-energizes, Y-2 will transfer to its alternate source, B
| |
| : 15. In this case, Y-2 should not have de-energized and auto transferred indicating a failure of the DC motor to maintain the MG set energized.
| |
| B. Correct: Y-2 should not have transferred and should have remained energized during the transient via the DC supply to the MG set. Y-2 will not automatically transfer back to its preferred source when B-6 is re-energized. Any Y-2 automatic transfer to B-15 must be manually reset.
| |
| C. Incorrect: Y-2 should not have transferred and must be manually re-aligned to its preferred source following the automatic transfer.
| |
| D. Incorrect: Y-2 must be manually re-aligned to its preferred source following an automatic transfer. Plausible in that if the MG set is being powering by the DC motor following a loss of B-6 power, and B-6 is subsequently restored, the MG set will automatically shift back to AC power. Additionally Y-1 will also auto transfer back to its preferred source if an automatic transfer to the alternate has occurred.

| A. Incorrect: One ARI valve is associated with each division. Only one ARI valve is required to depressurize the scram air header. Since only Division One tripped, only one ARI valve repositioned. Additionally, either division will trip both recirc pumps. The "B" MG set should have been tripped by the Division one logic.
| |
| B. Incorrect: Only one ARI valve repositioned.
| |
| C. Incorrect: The "B" MG set should have been tripped by the Division one logic.
| |
| D. Correct: Each division will energize its respective ARI valve which is sufficient to de energize the header. Each division will also trip BOTH recirc pumps. The "B" Recirc pump should have tripped.

| |
| * The plant is operating at full power.
| |
| * The Condensate Storage Tank (CST) low level switches have just been declared inoperable.
| |
| Which one of the following is correct regarding the impact on HPCI and RCIC?
| |
| A. HPCI and RCIC remain operable, due to a redundant suction source.
| |
| B. Only HPCI is inoperable, due to HPCI suction valve interlock being inoperable.
| |
| C. Only RCIC is inoperable, due to RCIC suction valve interlock being inoperable.
| |
| D. HPCI and RCIC are inoperable, due to HPCI and RCIC suction valve interlocks being inoperable.
| |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect - Both HPCI and RCIC have a redundant suction source using the Torus; however HPCI has an automatic suction transfer when water in the CST falls below a predetermined level. This suction interlock requires these CST low level switches be operable. RCIC does not have this automatic suction swap and therefore is unaffected by these switches becoming inoperable.

| |
| Low pressure ECCS will recover level when ADS ...
| |
| A. Initiates two minutes later. All four SRVs will open.

| |
| C. Initiates eleven minutes later. All four SRVs will open.
| |
| D. Initiates eleven minutes later. ONLY the "A" and "C" SRVs will open.
| |
| Proposed Answer: A Explanation (Optional):
| |
| A. Correct - A 105 second ADS timer is actuated by either a simultaneous occurrence of high drywell pressure (2.2 psig) and low-low RPV water level (-46 in.). Since the MSIVs also close at -46 inches, conditions have been met to start the timer. C903L-A 1 alarms when a loss of 125 VDC panel 0-4 occurs. This power loss disables ADS Logic Train "A"; however ADS Logic Train "B" is operable. The loss of any battery affects only one two minute timing circuit. Each relief valve is powered by DC from either station battery through auto-transfer switches. Therefore the ADS valves will open when the two
| |
| | |
| minute timer times out.
| |
| B. Incorrect - All four valves will open because each relief valve is powered by DC from either station battery through auto-transfer switches.
| |
| C. Incorrect - The loss of any battery affects only one two minute timing circuit. Each relief valve is powered by DC from either station battery through auto-transfer switches.

| |
| * RCIC is operating in Automatic at rated flow
| |
| * Then, an over-voltage transient on "A" 125 VDC syst'~m results in alarm RCIC INVERTER FAILURE, C904L A4.
| |
| * Three (3) seconds later, voltage on the "An 125 VDC system returns to normal.

| |
| | |
| Explanation (Optional):
| |
| A. Incorrect: The controller loses power and the output will fail to minimum, resulting in a reduction in turbine speed and flow.
| |
| B. Correct: The control circuitry for the RCIC System is 115V AC supplied by an inverter from the 125V DC Bus "A", A high voltage input condition (approximately 160V DC) will trip the inverter. The unit will automatically reset after the input voltage conditions return to normal with an approximately 3-second time delay, The loss of the 115V AC to the control circuitry will cause a reduction in the flow demand signal to the turbine.
| |
| C. Incorrect: The Inverter will auto reset. Plausible in that an earlier version of the inverter required a manual rest.

The #2 speed limiter initiates a runback by immediately changing the controller's output (demand signal to the scoop tube) to 44%. The operator monitors and verifies the response of the scoop tube via the Middle Bar Chart by observing changes in MG set speed.
| |
| Proposed Question: RO Question # 28 The "B" recirc MG set speed controller on the 904 panel is in MANUAL mode with the following initial indications on the controller:
| |
| * Left Bar Chart (Operator Setpoint): 70%
| |

| |
| | |
| Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect - The Left Bar is the Operator Set point and with the controller in Manual, will not automatically respond.
| |
| B. Incorrect - The Left Bar is the Operator Setpoint and with the controller in Manual, will not automatically respond. Additionally, the right bar chart is the output of the controller.
| |
| When the limiter is activated, the output of the controller will immediately drop to 44%.
| |
| This will in-turn reduce the MG set speed.
| |
| C. Correct - No.2 function will override controller output and will limit the speed demand signal to 44%, not subject to rate limiting. The left bar, the operator setpoint will not be changed by the runback to 44#. The center bar graph for controller indicates actual speed indication which would indicate 44% based on the #2 Speed Limiter. The right bar, indicating the controller output will indicate the new controller demand to the scoop tube, which would be 44% for the #2 Speed Limiter.
| |
| O. Incorrect - The right bar chart is the output of the controller. When the limiter is activated, the output of the controller will immediately drop to 44%. This will in-turn reduce the MG set speed.

| |
| * The plant was at rated conditions when a complete loss of normal feed resulted in a reactor scram.
| |
| * Control rods failed to insert and EOP-02, Failure to Scram, is being executed.
| |
| * RPV Pressure is being maintained between 900 and 1050 psig via SRVs
| |
| * RPV level has been intentionally lowered and is now being controlled between -150" and -125 inches (Actual)
| |
| * Standby liquid is being injected When will EOP-02 direct that RPV Level be restored to normal?

| NOT UNTIL. ....
| |
| A. Reactor Power is below the APRM downscales.
| |
| B. The Hot Shutdown Boron Weight has been injected C. The Cold Shutdown Boron Weight has been injected D. Reactor Power is on IRM range 7 or lower, and continuing to lower.
| |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect: Reactor level cannot be restored until the Hot Shutdown Boron Weight has been injected. Plausible in that this is one of the criteria for stopping the intentional lowering of level.
| |
| B. Correct: EOP-02, Step L-7 specifies that when the Hot Shutdown Boron Weight (HSBW) has been injected than the "R" leg of EOP-02 is to be executed. This leg directs that RPV level be restored to normal via step L-23.
| |
| C. Incorrect: Level can be restored when the HSBW has been injected. Delaying the level

| |
| * An inadvertent HPCI injection occurs
| |
| * The reactor automatically scrams in response to the transient What caused the reactor to scram?
| |
| A. Reactor power exceeded the IRM Hi-Hi setpoint B. Reactor power exceeded the APRM Hi-Hi setpoint C. Water level exceeded the high Main Turbine trip setpoint D. Water level exceeded the high MSIV Closure I isolation setpoint Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect: The IRMs will generate a scram when they exceed 120/125ths of scale. A reading of 100 on range 10 equates to - 32% power. Therefore the IRMs will not reach their high-high setpoint until power is somewhat greater than 32%. The APRM Hi-Hi will occur at 15% before power can reach that level.
| |
| B. Correct: With the mode switch in Startup, the APRM set down setpoints are in effect.

| This will cause a scram when power exceeds 15%. Therefore the reactor will scram on
| |
| | |
| APRM Hi-Hi.
| |
| C. Incorrect: Although the turbine may trip when level reaches +45 inches, the main turbine trips are bypassed due to the low 1s1 stage pressure in this condition (on the turning gear)

| |
| A. Incorrect -215°F is the limiting drywell temperature to guarantee that ECCS trips occur on/or before present T.S. values and requires a shutdown be initiated if drywell temperature cannot be restored to less than 215°F within 30 minutes. 281°F is the maximum internal design temperature of the drywell.
| |
| B. Incorrect -215°F is the limiting drywell temperature to guarantee that ECCS trips occur on/or before present T.S. values and requires a shutdown be initiated if drywell temperature is restored less than 215°F within 30 minutes.
| |
| C. Incorrect - The ADS SRV solenoids are designed to operate up to an ambient drywell temperature of 330°F.
| |
| D. Correct- lAW Primary Containment reference text Section C.1. , the maximum internal design temperature of the drywell is 281 degrees F. The ADS SRV solenoids are designed to operate up to an ambient drywell temperature of 330°F. Main Steam System reference text page 16 - Engineering determined that the ambient temperature
| |
| | |
| inside the drywell during a main steam line break may rise to 330°F The design basis MSLB is the most limiting break. This would cause the nitrogen inside the accumulator to increase in pressure due to the lack of area for expansion. The pressure would continue to rise to 160 psi. The 160 psi pressure exceeds the design rating of the previous accumulator (135 psi) solenoid valves. For this reason, new solenoid valves and relief valves designed to operate with a maximum Nitrogen pressure of 160 psid were installed on the accumulators. The maximum internal design temperature of the drywell is 281°F.

| |
| * The reactor is at 10% power
| |
| * EOP-03, Primary Containment Control has just been entered due to rising torus water temperature.
| |
| Based on the above EOP-03 requires that EOP-01, RPV Control, be entered before torus water temperature exceeds the _ _ (1) . The basis for this action is to __ (2) ?
| |
| A. (1) Heat Capacity Temperature Limit (2) ensure that, if possible, the reactor is scrammed and RPV pressure and level control are established prior to commencing an Emergency Depressurization B. (1) Heat Capacity Temperature Limit (2) ensure that, if possible, the reactor is scrammed in order to limit additional heat input to the torus to prevent incomplete steam condensation following a blowdown.
| |
| C. (1) Boron Injection Initiation Temperature Limit (2) ensure that, if possible, the reactor is scrammed and shutdown by control rod insertion before the requirement for boron injection is reached. If rods fail to insert, sufficient boron can be injected before torus water temperature exceeds the Heat Capacity Temperature Limit.
| |
| D. (1) Boron Injection Initiation Temperature Limit (2) ensure that, if possible, the reactor is scrammed and shutdown by control rod insertion before the requirement for boron injection is reached. If rods fail to insert, sufficient boron can be injected before torus water temperature exceeds low pressure ECCS NPSH requirements.
| |
| Proposed Answer: C Explanation (Optional):
| |
| | |
| A. Incorrect: Per EOP-03, step TT-9, EOP-01 is entered before the torus water temperature exceeds the Boron Injection Initiation Temperature limit. Emergency Depressurization is required when the HCTL is exceeded which is much higher than the BIIT limit.
| |
| B. Incorrect: Per EOP-03, step TT-9, EOP-01 is entered before the torus water temperature exceeds the Boron Injection Initiation Temperature limit.
| |
| C. Correct: Per EOP-03, step TT-9, EOP-01 is entered before the torus water temperature exceeds the Boron Injection Initiation Temperature limit. Per the EOP-03 LP, Entering EOP 01 at Step R-1 assures that, if possible, the reactor is scrammed and shutdown by control rod insertion before the requirement for boron injection is reached. Conditions requiring entry into EOP-03 do not necessarily require entry into the RPV Control guideline.
| |
| Therefore, a scram may not have yet been initiated. Also at 10% power the BIIT is 121 degrees. This is, the temperature at which initiation of boron injection will permit injection of the Hot Shutdown Boron Weight (HSBW) before torus water temperature exceeds the Heat Capacity Temperature Limit (HCTL).
| |
| D. Incorrect: The BIIT curve It is the greater of either the highest torus water temperature at which initiation of boron injection will permit injection of the Hot Shutdown Boron Weight (HSBW) before torus water temperature exceeds the Heat Capacity Temperature Limit (HCTL) or the torus water temperature at which a reactor scram is required by Technical Specifications (11 OQF). At 10% power the temperature the HCTL is limiting.

| * ATWS conditions exist
| |
| * EOP-02, Failure to Scram, is being executed
| |
| * All three main turbine bypass valves are open
| |

| |
| * The plant is at rated power
| |
| * "B" Recirc MG Set AC Lube Oil Pump P22S8 is running
| |
| * "8" Recirc MG Set AC Lube Oil Pump P225A is danger tagged out of service Then ...
| |
| * 12S VDC bus D-S is lost
| |
| * Two minutes later the reactor operator reports that current on the "B" Recirc MG set is pegged high and that P22SB is not running Which one of the following actions is required by PNPS S.3.12, LOSS OF ESSENTIAL DC 8US D17 OR DS AND D37, AND why?
| |
| A. Manually trip 4KV bus A4 at panel C3. This will de-energize the "B" Recirc MG set.
| |
| : 8. Locally trip the "B" Recirc MG Drive motor breaker at 4KV bus A4. The Recirc MG set is seized due to a loss of lube oil.
| |
| C. Locally start the "8" Recirc System DC Emergency Bearing Oil Pump at 250 VDC panel D9. The Recirc MG set is seized due to a loss of lube oil.
| |
| D. Manually scram the reactor. Scramming the reactor will cause the turbine to trip, resulting in a loss of 4KV bus A4, de-energizing the "8" Recirc MG set Proposed Answer: D Explanation (Optional):
| |
| A. Incorrect: P22SB tripped as expected following the loss of DS. With no AC lube oil pumps running the MG set is seizing. However with the loss of DS, bus A4 is also without control power.
| |
| | |
| B. Incorrect - The procedure directs that the MG set be tripped locally but only if the current is NOT pegged high due to the electrical hazard of tripping the breaker under such a high load.
| |
| C. Incorrect: Starting the DC pump will not alleviate the condition as it only supplies oil to the coupler bearings and not the motor and generator bearings.
| |
| D. Correct - Per the procedure, if there is indication of severe bearing damage (locked rotor condition), then a Scram is initiated and the resulting Turbine trip will de-energize the Unit Auxiliary Transformer, which in turn results in de-energizing Bus A4 and thereby securing the "B" Recirc MG Set.

| |
| Which one of the following failures or conditions could result in exceeding the NEGATIVE design pressure rating of the containment?
| |
| A. Torus to drywell vacuum breaker failing open.
| |
| B. Torus level rising to 190 inches with drywell sprays in service.
| |
| C. Torus level rising to 175 inches with torus sprays in s!3rvice.
| |
| O. SRV tailpipe vacuum breaker failing closed.
| |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect - This event would challenge the over pressure rating of the containment as steam would bypass the suppression pool.
| |
| B. Correct: At 180 inches the Torus to Drywell Vacuum Breakers begin to be covered.
| |
| With drywell sprays in service, the vacuum breakers would be unable to relieve back to the drywell, resulting in the drywell going negative in pressure. EOP-03, step TL-10 directs that drywell sprays be secured at this level C. Incorrect -175 inches is the point at which the SRVTPLL becomes limiting. If the SRVTPLL failed, a potential loss of pressure suppression might occur which is a ~Iigh pressure challenge to the containment.
| |
| D. Incorrect - A SRV Tailpipe vacuum breaker failing closed would result in a vacuum drag of water up the tailpipe. Subsequent SRV lifts would result in large hydro dynamic forces on the tailpipe with possible failure. At most this would result in a high pressure condition if the tail pipe failed.

| |
| * The plant has been operating at 2028 MWt for the past week.
| |
| * A complete loss of the process computer now occurs.
| |
| * Operators perform a manual heat balance as directed by PNPS 2.1.10 COMPUTER DATA AND ALARMS

| * The heat balance indicates that the reactor is operating at 2040 MWt Which one of the following is correct as prescribed in PNPS 2.1.10 COMPUTER DATA AND ALARMS?
| |
| A power reduction is ..... .
| |
| A. currently required to maintain thermal power less than the licensed power level of 2028 MWt.
| |
| B. not currently required. Provided that future heat balances do not exceed 2040 MWt a power reduction will not be required.
| |
| C. not currently required. Provided that future heat balances do not exceed 2055 MWt a power reduction will not be required.
| |
| D. currently required to lower thermal power to less than 1998 MWt due to loss of the AMAG computer.
| |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect: A power reduction is not required. As discussed in PNPS 2.1.10, a manual heat balance may be up to 3% off from that calculated by the Process computer.
| |
| | |
| B. Correct: As discussed in 2.1.10, the result of the heat balance is known to be up to 3%
| |
| high. The initial heat balance done following the computer loss considered to be equal to the preloss computer value.
| |
| Example: Prior to computer loss, 3DM Core Power And Flow Log power =1995, manual heat balance power = 2024, and no system changes have taken place. Since a difference is known to exist in the manual heat balanc:e due to data inaccuracies and no system changes have occurred, then 3DM power is the same as heat balance power and the baseline difference is set equal to 29 MWth. Future heat balances that indicate greater than this 29 MWth difference would require power reductions equal to the amount that is greater than the baseline difference.
| |
| C. Incorrect: A power reduction would be required if calculated power exceeded 2040 MWt. Plausible in that PNPS 2.1.14 requires operator action be taken if instantaneous power exceeds 2055 MWt.
| |
| D. Incorrect: Plausible in that the AMAG computer is what allows the plant to reach 2028.
| |
| If the plant was being maneuvered, power could not exceed 1998. (ARP 905R-F8) Note that the AMAG computer has also been lost.

The following conditions exist:
| |
| * Reactor pressure is being maintained in a band of 450-550 psig
| |
| * Reactor level as indicated on Narrow Range Level Indicators U-263-100A and B is -42 inches and slowly rising

| |
| | |
| "B".
| |
| D. cannot be determined Exit EOP-01 and enter EOP-16, RPV Flooding and commence flooding the RPV using all available low pressure systems.
| |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect: Per EOP Caution 1, the minimum useable level for the Narrow Range Instruments is -35 inches. Due to the high Rx Building temperatures (Rx Building not accessible) it must be assumed that level is below the variable leg tap and that the instrument is showing a rising level due to reference leg heatup. The fuel zone instrument is not susceptible to this issue and is reflecting actual level changes. If actual level was -42 inches and the fuel zones were deemed not reliable, this would be the action.
| |
| B. Correct: The fuel zone instruments are still reliable. Even though there are high reactor building temperatures there is no indication of flashing. However, they are still off calibrated conditions. Using PNPS 2.2.80, Attachment 8, Figure 2, and given a pressure of 450 - 550 psig, TAF is -155 inches. Therefore actual level is at TAF or, -125 inches. Per EOP-01 the direction is to line up systems for emergency depressurization.
| |
| EOP-17 must be entered when level cannot be restored and maintained above -150".
| |
| Per PNPS 5.3.35.2 the direction is to Enter EOP-17 as soon as level drops below TAF and there is reasonable assurance that the low pressure systems can recover level.

| |
| Assuming conditions do not improve how long can the plant continue to operate?
| |
| A. 24 hours B. 3 days C. 7 days D. 12 days Proposed Answer: B Explanation (Optional):
| |
| | |
| A. Incorrect: Plausible in that this would be correct if TS 3.5.F was not met. Although HPCI is inoperable and is a Core Cooling System it is not a low pressure system. 3.5.F states that during any period when one emergency diesel generator (EDG) is inoperable, continued reactor operation is permissible only during the succeeding 72 hours unless such EDG is sooner made operable, provided that all of the low pressure core and containment cooling systems shall be operable, and the remaining EDG shall be operable in accordance with 4.5.F.1. If this requirement cannot be met, an orderly shutdown shall be initiated and the reactor shall be placed in the Cold Shutdown Condition within 24 hours.
| |
| B. Correct: The 250 VDC battery is inoperable. Per Tech Spec bases, battery voltage must be greater than 210 VDC for the battery to be operable. Tech Spec 3.9.B.5 specifies that from and after the date that the 250 volt battery system is made or found to be inoperable for any reason, continued reactor operation is permissible during the succeeding three days provided repair work Is initiated in the most expeditious manner to return the failed component to an operable state, and Specification 3.5.F is satisfied.
| |
| 3.5.F remains satisfied.
| |
| C. Incorrect: The 250 VDC battery is inoperable. Tech Spec 3.9.B.5 allows continued operation for only three more days. Plausible if the candidate thinks that a loss of the 250 VDC system affects the RHR system which is a 7 day LCOs. Although 250 VDC is the power supply to RHR valve MO-1001-47, a loss of power does to this valve does not render RHR inoperable.
| |
| D. Incorrect: The 250 VDC battery is inoperable. Plausible in that if the battery was considered operable, the EDG LCO would be limiting.

| |
| | |
| D. An Alert at time 00: 50 A Site Area Emergency at time 00: 60 Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect: An EAL has not yet been exceeded at time 00:05. Plausible in that a UE is required if all off-site power is lost. However the Shutdown Transformer is still an available off-site power source negating the necessity to declare the UE. An Alert is also not required. Plausible in that an Alert would be required if the fire was burning out of control. There was no evidence that the fire was "out of control" and spreading.
| |
| B. Incorrect: A UE was exceeded when off-site fire fighting assistance was requested per EAL 7.2.1.1. However a SAE was never exceeded during the event. Plausible in that "any fire which has affected the ability of two or more safety systems (Table 7-1) to perform their intended function and poses a significant potential for release of radioactivity" would result in a SAE per EAL 7.2.1.3. Although multiple safety systems are affected (Core Spray, RHR, SBGT etc.) the plant can still achieve cold shutdown and there is no significant potential for a release.
| |
| C. Correct: The SM was required to declare UE when off-site fire fighting assistance was requested per EAL 7.2.1.1 at time 00:35. No other EALs were exceeded.
| |
| D. Incorrect: The SM was required to declare UE when off-site fire fighting assistance was requested per EAL 7.2.1.1 at time 00:35. An Alert was also not required as discussed above. A SAE was also never exceeded as discussed above.

| |
| * Drywell Spray has just been initiated using "A" and "B" RHR pumps
| |
| * "C" and "0" RHR pumps are secured
| |
| * RHR flow in each loop is 5000 gpm.

| |
| A. The HCTL IS being exceeded. The RHR NPSH will be exceeded when Torus bottom pressure lowers to below 5 psig.
| |
| | |
| B. The HCTL IS being exceeded. The RHR I\JPSH will NOT be exceeded provided there is no further degradation in Torus Water Temperature or Torus Water Level.
| |
| C. The HCTL Is NOT being exceeded. The RHR NPSH will be exceeded when Torus bottom pressure lowers to below 5 psig.
| |
| D. The HCTL Is NOT being exceeded. The RHR NPSH will NOT be exceeded provided there is no further degradation in Torus Water Temperature or Torus Water Level.
| |
| Proposed Answer: A Explanation (Optional):
| |
| A. Correct: At an RPV Pressure of 700 PSIG and a Torus level of 110 inches the HCTL is exceeded when torus water temp exceeds 185 degrees. The NPSH for each pump per loop running at 5000 gpm and 190 degrees torus water temperature will be exceeded when torus bottom pressure lowers to less than 5 psig. Given a torus water level of 110 inches, torus bottom pressure will lower as low as - 4 psig following drywell spray initiation.
| |
| B. Incorrect: The RHR pump NPSH limit will eventually be exceeded as drywell sprays lower the pump over pressure. Plausible in that if the "2 pump value" of 5000 gpm is used it would not appear that the limit would be exceeded as the torus water temperature limit would be - 195 degrees. (drywell sprays could not lower the torus bottom pressure to any lower than - 4 psig due to the weight of the water).
| |
| C. Incorrect: At an RPV Pressure of 700 PSIG and a Torus level of 110 inches the HCTL is exceeded when torus water temp exceeds 185 degrees. Plausible in that if the torus water level line of 127 inches is used, the HCTL would not be exceeded until - 195 degrees.
| |
| D. Incorrect: At an RPV Pressure of 700 PSIG and a Torus level of 110 inches the HCTL is exceeded when torus water temp exceeds 1185 degr,ees. Plausible in that if the torus water level line of 127 inches is used, the HCTL would not be exceeded until - 195 degrees.

| |
| Given the following:
| |
| * The reactor had been operating at 100% power for an extended period when a rising drywell pressure resulted in an automatic scram;
| |
| * Several control rods failed to insert;
| |
| * EOP-02, Failure to Scram has been entered and the RO is inserting rods manually;
| |
| * Reactor Power is on range 2 of the IRMs and lowering;
| |
| * RPV Level is being maintained +12 inches to +45 inches utilizing the feed system.
| |
| * No boron has been injected;
| |
| * An RPV cooldown has commenced utilizing turbine bypass valves.
| |
| With these conditions, the reactor operator reports that power has now risen to range 6 of the IRMs and is continuing to slowly rise.
| |
| Which one of the following is required and the bases for that action?
| |
| A. Terminate injection lAW PNPS 5.3.35.1 ATTACHMENT 35 - STOP AND PREVENT INJECTION CHECKLIST and lower level to below -25 inches in order to decrease the amount of inlet subcooling and thereby reduce power.
| |
| B. Stop reducing pressure and stabilize pressure below 1060 psig lAW EOP-02 Step P-5 to allow the negative temperature coefficient and the reactor operator to insert additional rods to shutdown the reactor.
| |
| C. Stop reducing pressure and inject Boron lAW PNPS 5.3.35.1 ATTACHMENT 44 INITIATION OF STANDBY LIQUID CONTROL. Once boron injection has commenced continue reducing pressure because the boron injection can overcome any positive reactivity addition by the cooldown.
| |
| D. Terminate injection lAW PNPS 5.3.35., 1 ATTACHMENT 35 - STOP AND PREVENT INJECTION CHECKLIST and lower level as required until power lowers to range 6 of the IRMs in order to reduce the amount of natural circulation in the core. Do not intentionally lower level below -125".
| |
| | |
| Proposed Answer: B Explanation (Optional):
| |
| A. Incorrect: Injection is not terminated and prevented and level lowered to <-25" unless power is above 3%.
| |
| B. Correct: Per EOP-02, step P-7, the direction is to stabilize pressure below 1060 psig when the reactor is not shutdown. PNPS 5.3.35 defines reactor shutdown as being on IRM range 7 or lower and power continuing to lower. Stopping the pressure reduction adds negative reactivity be allowing the reactor to re-pressurize and the operator time to insert more control rods.
| |
| C. Incorrect: Once the decision is made to inject boron, further intentional cool down is not allowed until the cold shutdown boron weight has been injected.
| |
| D. Incorrect: Injection is not terminated and prevented and level lowered to control power unless power is above 3% and torus temperature is above the BITT.

| |
| * The plant is at 100%
| |
| * APRM "A" has failed upscale and is bypassed
| |
| * Several LPRM detectors that input into APRM channel "C" have been bypassed
| |
| * The current status of APRM "C" LPRM inputs are as follows:

| (1) Prior to any operator action, what will be the impact of the LPRM failure on APRM "C" (assume all LPRMs were reading the same at the time of the failure)
| |
| ANO (2) Which of the below actions are required for this condition?
| |
| A. (1 ) APRM "C'''s output will lower.
| |
| (2) Enter PNPS 2.4.38, LPRM Failure, bypass LPRM 04-37-8, verify / adjust AGAFs and continue operation without any additional restrictions.

| |
| | |
| C. (1 ) APRM "C"'s output will lower.
| |
| (2) Enter Tech Spec LCO 3.1.1. If APRM "A" or "G" is not restored within the next 12 hours, trip RPS "An or take other equivalent action authorized by Tech Specs.

| |
| (2) Enter Tech Spec LCO 3.1.1. If APRM "A" or "c" is not restored within the next 12 hours, trip RPS "A" or take other equivalent action authorized by Tech Specs.
| |
| Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect: Per TS Table 3.1.1, note 13, an APRM is considered operable if it has two LPRMs per level. That is no longer the case in that there is only one remaining "B" level detector. Plausible in that if this is not recognized, PNPS 2.4.38, would have you bypass the LPRM and verify AGAFs since there are still more than 10 LPRMs available
| |
| << 10 will generate an INOP trip)
| |
| B. Incorrect: The APRM output will lower. Plausible in that unlike the RBM, the APRM does not use downscale trip units which would automatically remove the LPRM from the averaging circuit.
| |
| C. Correct: With the additional failure there are too few LPRM inputs for level B (minimum is 2 and only 1 is available) and APRM "c" is inop. With two APRMs INOP associated with RPS "A", Tech Spec Table 3.1.1 condition "a" specifies that RPS "An must be tripped within 12 hours or actions A or B initiated D. Incorrect: The APRM output will lower. Plausible in that unlike the RBM, the APRM does not use downscale trip units which would automatically remove the LPRM from the averaging circuit.

| |
| Question Justification: In order to answer this question, candidates must apply previous PNPS system Operating Experience (LER) to the condition presented. This information is not documented in the PNPS Tech Specs or its associated bases but captured in plant procedures that are not provided as references to the candidates. Integrating their knowledge of the operating experience, candidates must recognize that the LPCI function is inoperable and then apply this condition to the existing HPCI LCO. Other distracters are based on a common misunderstanding that the operating experience requires that a Suppression Pool Cooling subsystem of RHR is to be declared inoperable since that is the existing RHR lineup.
| |
| Therefore this question is not a "direct lookup".
| |
| Proposed Question: SRO Question # 88 Given the following:
| |
| * The plant is at 100% power
| |
| * HPCI has been declared inoperable and is on day 2 of a 14 day LCO
| |
| * RHR Loop "A" is placed into torus cooling to support post work testing of the HPCI system (1) The SRO is required to declare:
| |
| AND (2) The most limiting LCO is:

| |
| | |
| Proposed Answer: B.
| |
| Explanation (Optional):
| |
| A. Incorrect: LPCI is required to be declared INOP. With HPCI already inoperable TS 3.5.C.3 requires that a 24 hour cold SID LCO be entered.
| |
| B. Correct: Whenever the LPCI System is in the Torus Cooling mode of operation LPCI is to be declared inop <<Tech Spec 3.5.A). This is based on a postulated accident scenario that involves a LOOP-LOCA while in Torus Cooling and a single failure of an EDG. With the loss of the EDG, the Torus Cooling valves will lose power and remain open, diverting flow to the Torus during the subsequent LPCI injection with the remaining two LPCI pumps. With HPCI already inoperable TS 3.5.C.3 requires that a 24 hour cold SID LCO be entered.

| Proposed Question: SRO Question # 89 Given the following:
| |
| * Power has been reduced to 40% with a plant shutdown in progress
| |
| * A momentary loss of 120VAC Vital Bus Y-2 occurs when the Vital MG set trips
| |
| * Y -2 is now re-energized
| |
| * RPV level is 32 inches and slowly rising Based on these conditions the CRS is required to enter:
| |
| A. PNPS 5.3.6, LOSS OF VITAL AC (Y2) and direct resetting the Feed Reg Valves lockups, the Recirc runback, and scoop tube locks.
| |
| B. PNPS 5.3.6, LOSS OF VITAL AC (Y2) and direct resetting the Recirc runback and scoop tube locks. Direct Recirc pump speed be increased to stabilize level until the Feed Reg Valves are locked in the condenser compartment.
| |
| C. Enter PNPS 2.4.49, FEEDWATER MALFUNCTIONS and direct that the Feed Reg Valves be locked in the Condenser Compartment. Enter PNPS 2.4.36, DECREASING CONDENSER VACUUM and direct re-opening AO-3751, Off Gas Isolation Valve.
| |
| D. Enter PNPS 2.4.49, FEEDWATER MALFUNCTIONS and direct that the Feed Reg Valves be locked in the Condenser Compartment. Enter PNPS 2.4.20, REACTOR RECIRCULATION SYSTEM SPEED OR FLOW CONTROL SYSTEM MALFUNCTION and direct resetting the scoop tube locks.
| |
| Proposed Answer: A Explanation (Optional):
| |
| A. Correct: PNPS 5.3.6, LOSS OF VITAL AC (Y2) provides direction on how to stabilize the plant after a momentary loss of Y-2. Resetting the FRV lockups will stabilize level.
| |
| Resetting the run backs and then the scoop tube locks will restore speed control.
| |
| | |
| B. Incorrect: RPV level is stabilized by resetting the FRV lockups. Plausible in that raising reactor power would help stabilize the level rise.
| |
| C. Incorrect: The Feed Reg Valves can be reset on C905 following a momentary loss of Y
| |
| : 2. Plausible in that PNPS 2.4.49, Feedwater Malfunctions, directs that if the FRVs are locked and the valves are drifting open or closed, that the valves should be locked in the condenser compartment. Procedure 2.4.36 is plausible in that the off-gas isolation valve did go close during the Y-2 loss and would have re-opened once power was restored.
| |
| D. Incorrect: PNPS 2.4.49 is plausible for the reason discussed above. PNPS 2.4.20 is also plausible in that the Recirc pumps locked up following the loss of Y-2.

| |
| SRO Level Justification: he Safety Parameter Display System (SPDS) a NPS is a subset of the overall PNPS process omputer also known as EPIC. Whereas all erators utilize the general process computer f ctions to monitor plant status, the SPD unction is the purview of the SRO. This is stated e licitly in PI\IPS 2.6.1 EMERGENCY 0 PLANT INFORMATION COMPUTER ( IC) SYSTEM DISPLAY, on pag 6, when it states that "The Shift Control Room Engineer (S E) is designated as the prim SPDS user". The procedure goes on to state that th rimary location for the S S displays is to be on one of the Control Room Supervisor (CRS) omputer displays. B the SCRE and CRS positions are only filled by SROs at PNPS.
| |
| ed by all operators are similar to those within the SPDS there are significant, addi' nal SP features that are not used within the process computing functions. For example, PIC isplays alarms and instrument readings using three general colors - green (normal), y I (approaching an alarm setting), and red (exceeding an alarm setting). SPDS uses the ame colors plus, white, cyan, dark blue, and magenta. Additionally for some common co rs s ch as yellow, the color means different things depending on the particular SPDS . play. r example, unlike EPIC in general, the displays for critical plant parameters utili inputs fro multiple instruments and go through extensive validation. If the validation orithms deter ine that there are insufficient inputs or the inputs are suspect, the SPDS w s the SRO that t display has not been validated and its value is suspect by outlining the alue in yellow. A ye w display on EPIC means that the value is approaching an alarm se oint. In summary, if the RO candidates based their response to this question on th r knowledge of EPIC color nventions they would arrive at an incorrect response.
| |
| Proposed Question: o Question # 90
| |
| * React level is +30" on the feedwater range level indication and s ady.
| |
| * On t SPDS Critical Plant Variables Display, the digital readout for PV "ACTUAL LE L" is displayed in YELLOW numbers reading +32" and surround by a YELLOW b rder.
| |
| OS display means that the SPDS calculated RPV water level ...... .
| |
| | |
| A. has exceeded the allowable difference between the calculated value and the output of the feedwater level control instruments.
| |
| B. has reached the high level alarm setpoint.
| |
| C. has insufficient data to validate the calculation D. is using at least one bad data input in its calculation.
| |
| Proposed Answer: C Explanation (Optional):
| |
| A. Incorrect: The SPDS value for level is calculated via inputs from several instruments.
| |
| Instruments are compared to one another to determine whether any single instrument has failed but not to the calculated SPDS value.
| |
| B. Incorrect: The yellow border means that the calculation has not been validated.
| |
| Plausible, in that Operational Limit tags will change to yellow when they are approaching an alarm limit. +32 inches is the alarm setting for the feedwater level control system high level alarm.
| |
| C. Correct: The yellow border means that the value has not been satisfied. Plausible in that some displays such as SPDS Alarms and parameters plotted on graphs will turn yellow if the measured value is approaching a limit.
| |
| D. Incorrect: Bad data would result in a magenta display.

| |
| * The reactor scrammed 2 minutes ago due to low RPV water level.
| |
| * RPV water level is currently +5 inches and slowly recovering
| |
| * All but six control rods can be verified as having fully inserted.
| |
| * The RO reports the following indications for the six rods:
| |
| o Neither the Full In or Full Out lights are illuminated on the full core display.
| |
| o The four rod display for these rods indicate "black-black" o EPIC and SPDS Rod Position Displays indicate magenta *** for these six rods o CALLRODS indicates "YES" Which one of the following is correct?
| |
| A. Reactor shutdown status has been confirmed. Rema.in in EOP-01 and direct normal scram recovery actions.
| |
| B. Reactor shutdown status cannot be determined. Exit EOP-01 and Enter EOP-02 and attempt to insert the control rods.

| |
| D. CALLRODS has been triggered but has not yet confirmed rod insertion. Remain in EOP-01 for an additional minute before making a determination of rod position.
| |
| Proposed Answer: A Explanation (Optional):
| |
| | |
| A. Correct: These are the RPIS indications for rods that have gone beyond full-in following the scram. The CALL RODS program detected that the six rods have passed through the 04 position (Max Subcritical Bank Withdrawn Position) as indicated by the word "YES". All rods have been inserted beyond the Max Subcritical Bank Withdrawn Position and stabilization efforts are governed by EOP-01 B. Incorrect: These are the RPIS indications for rods that have gone beyond full-in following the scram.

| Proposed Question: SRO Question # 96 Following a reactor shutdown the following conditions exist:
| |
| * The "A" Miscellaneous Tank is being prepared for overboard discharge
| |
| * The Prerelease Permit listed the following Seawater and Salt Service Water Pump Lineup:
| |
| o "An and "8" Seawater pumps in service o "A" and "D" Salt Service Water pumps in service.
| |
| While reviewing the Release Permit, the Shift Manager notes that the above lineup has changed to:
| |
| * "A" Seawater Pump in service and "8" Seawater Pump secured
| |
| * "N' and "En Salt Service Water pumps in service Which one of the following is correct regarding the discharge?
| |
| The discharge:
| |
| A. Is NOT permitted because the "8" Seawater Pump is secured.
| |
| : 8. Is NOT permitted because the Salt Service Water pump configuration has changed.
| |
| C. Is permitted because the minimum criterion of at least one Seawater pump in service is satisfied.
| |
| D. Is permitted because the minimum criterion of at least one Seawater Pump and two Salt Service Water Pumps is satisfied.
| |
| Proposed Answer: A Explanation {Optional}:
| |
| | |
| A. Correct: The Shift manager is required to verify that the dilution pump combination is the same as on the prerelease report prior to authorizing the discharge. The dilution pump combination is based on the number of SW and SSW pumps running. With the "8" seawater pump secured, the dilution flow used in the prerelease calculations is now less than the existing dilution flow.
| |
| : 8. Incorrect: The release cannot be authorized because the dilution flow assumed has changed in that the "8" Seawater pump is not running. The combination of dilution pumps is based on the number of SSW pumps running and not the specific pumps in service.
| |
| C. Incorrect: The release cannot be authorized because the dilution flow assumed has changed in that the "B" Seawater pump is not runnin!~.
| |
| D. Incorrect: The release cannot be authorized because the dilution flow assumed has changed in that the "8" Seawater pump is not running.

| Proposed Question: SRO Question # 97 With the unit at 55% power, a high Stator Water Cooling temperature condition results in a Turbine Generator run back. The plant is now stable with the following conditions:
| |
| * Reactor level and pressure are within their normal ranges
| |
| * One Turbine Bypass Valve is OPEN Which one of the following is required by PNPS 2.4.156, Stator Cooling Water Malfunctions and what is the reason for this action?
| |
| A. Lower power using PNPS 2.1.14 Station Power Changes to close the bypass valve.
| |
| B. SCRAM the Reactor AND ENTER PNPS 2.1.6, Reactor Scram to close the bypass valve.
| |
| C. Raise the Load Limit using PNPS 2.2.99, Main Turbine Generator to restore feedwater temperature to within the limits of 2.4.150, Loss of Feedwater Heating.
| |
| D. Raise the Speed Load Changer using 2.1.14 to restore feedwater temperature to within the limits of 2.4.150, Loss of Feedwater Heating.
| |
| Proposed Answer: A Explanation (Optional):
| |
| A. Correct - Procedure specifies a power reduction to close the bypass valve B. Incorrect - Procedure directs that a power reduction be conducted to close the bypass valve
| |
| | |
| C. Incorrect - Procedure directs that a power reduction be conducted to close the bypass valve. Plausible in that the bypass valve being open is resulting in a partial loss of feedwater heating. If the candidate believes that the load limit is the device that is actuated during a runback, then this action would close the bypass.
| |
| D. Incorrect - Procedure specifies a power reduction to close the valve. Raising speed load changer would close the valve but also re-initiate the runback Technical Reference(s): 2.4.156, Sect. 3.0 & 4.0 (Attach if not previously provided)
