| |
| * Movement of irradiated fuel is in progress in Containment and the Auxiliary Building
| |
| * All administrative requirements for fuel movement are satisfied Which ONE of the following conditions, if it were to subsequently occur, would require core alterations to be SUSPENDED?
| |
| A. Reactor cavity boron concentration is 2590 ppm B. 'B' RHR Pump has been determined to be INOPERABLE C. Refueling cavity level is 23' 8" and lowering by 0.5" per hour D. Containment Purge has automatically been secured while performing ESFAS testing Answer: A Explanation (Optional):
| |
| A. CORRECT. According to Technical Specification 3.9.1, Boron Concentration "Boron concentrations of the RCS, refueling canal, and the refueling cavity shall be maintained within the limits specified in the COLA (COLA, 2.11 states 2750 ppm)." LCO Action Statement A "Boron concentration not within limit" has a Required Action of "Suspend CORE ALTERATIONS" with a Completion Time of "Immediately".
| |
| B. INCORRECT.
| |
| Plausible since both RHR loops are required to be OPERABLE if cavity level is< 23 feet according to Technical Specification 3.9.5. Incorrect since cavity level is> 23 feet and slowly lowering, Technical Specification 3.9.4requires one RHR loop to be OPERABLE and in operation.
| |
| C. INCORRECT.
| |
| Plausible Technical Specification 3.9.6 requires cavity water level to be maintained 23 feet above the top of the reactor vessel flange and requires an immediate suspension of core alterations if water level is< 23 feet. Incorrect since refueling water cavity level is > 23 feet and slowly lowering, the operating crew has the ability to maintain ES-401 Sample Written Examination Question Worksheet water level within limits with normal sources of makeup water. Form ES-401-5 D. INCORRECT.
| |
| Plausible if the candidate believes that CNMT Purge operation is required for fuel movement and since Technical Specification 3.9.3 requires "Each penetration providing direct access from the CNMT atmosphere to the outside atmosphere shall be either closed or capable of being closed by an OPERABLE CVI System" and the CNMT Purge System is in operation during outage conditions.
| |
| If these requirements are not met then core alterations are immediately suspended.

UFSAR Section 8.3.2.2 states "Each of the two station batteries is capable of carrying its expected shutdown loads following a plant trip and a loss of all ac power for a period of 4 hours without battery terminal voltage falling below 108.6 V." B. INCORRECT.
| |
| Plausible as the first part is correct and the time limitation is that for the EOP network if coping strategies, such as shedding DC loads, are performed.
| |
| C. INCORRECT.
| |
| Plausible since a Normal Float Charge would provide a battery voltage of 135 +/- 0.5 VDC and the candidate may believe that normal battery voltage while on a Float Charge is approximately 140 VDC. The second part is correct. D. INCORRECT.

| |
| RO Question #5 Given the following plant conditions:
| |
| * An SI due to a LOCA outside of Containment has occurred RO 1 1 Form ES-401-5 SRO EPE W/E04 EK1 .3 3.5
| |
| * The source of RCS leakage is back-leakage from either V-853A or V-8538, RHR INLET CHECK VALVES TO THE REACTOR VESSEL CORE DELUGE LINE
| |
| * The leak location is on the common RHR HX discharge line to the reactor vessel and Loop '8' cold leg
| |
| * The crew has transitioned from E-0, REACTOR TRIP OR SAFETY INJECTION, to the appropriate procedure Which of the following identifies:
| |
| (1) The component that, when closed, would result in leak isolation, AND (2) The SI flow change as a result of the successful leak isolation.

| |
| Sample Written Examination Question Worksheet Form ES-401-5 A. INCORRECT.
| |
| Plausible because MOV-720 is checked in ECA-1.2, but it is a verification of a normally shut valve for a normal alignment.
| |
| For the given conditions there would be NO change in parameters even if the valve had started from the OPEN position as back-flow leakage would not be isolated.
| |
| Second part is plausible, if candidate does not know that leak isolation would cause RCS pressure to rise and SI flow to lower, due to SI pumps approaching dead head conditions.
| |
| B. INCORRECT.
| |
| Plausible because MOV-720 is checked in ECA-1.2, but it is a verification of a normally shut valve for a normal alignment.
| |
| For the given conditions there would be NO change in parameters even if the valve had started from the OPEN position as back-flow leakage would not be isolated.
| |
| The second part is correct. C. CORRECT. In accordance with ECA-1.2, MOV-852A and MOV-852B are closed one at a time to attempt leak isolation.
| |
| Since the given leak location is upstream of failed check valve 853A or 853B, isolation is accomplished once MOV-852A or MOV-852B is closed. ECA-1.2 uses indication of RCS pressure rising for leak isolation which corresponds to SI flow lowering as repressurization occurs. D. INCORRECT.
| |
| Plausible as the first part is correct and the candidate may confuse the RCS pressure response with the applicable SI flow response.

PCV-135 eosition RV-203 eosition A. OPEN CLOSED B. OPEN OPEN C. CLOSED CLOSED D. CLOSED OPEN Answer: D Explanation (Optional):
| |
| A. INCORRECT.
| |
| Plausible if the candidate does not recognize that PT-135 senses pressure upstream of PCV-135 which results in the valve closing to attempt to raise pressure.
| |
| Also, plausible if the candidate does not recognize that Relief Valve 209 is located downstream of PCV-135 and therefore will not lift. B. INCORRECT.
| |
| Plausible if the candidate does not recognize that PT-135 senses pressure upstream of PCV-135 which results in the valve closing to attempt to raise pressure.
| |
| Also, the second part is correct. C. INCORRECT.
| |
| Plausible since the first part is correct and if the candidate does not ES-401 Sample Written Examination Question Worksheet Form ES-401-5 recognize that Relief Valve 209 is located downstream of PCV-135 and therefore will not lift. D. CORRECT. PCV-135 controller would get a low input for letdown system pressure and compare that to the setpoint (normally 250 psig). The controller would then send a control signal to CLOSE PCV-135 in an attempt to raise pressure, but would not see a change due to the failed pressure transmitter.
| |
| Eventually PCV-135 would CLOSE causing Relief Valve 203 to lift at 600 psig to the PRT. Technical Reference(s): (Attach if not previously provided, including version/revision number) 33013-1264 (Rev 028) Proposed references to be provided to applicants during examination:

| |
| Injection Steam Line Isolation A. Will initiate Will NOT initiate B. Will NOT initiate Will NOT initiate C. Will initiate Will initiate D. Will NOT initiate Will initiate Answer: A Explanation (Optional):
| |
| A. CORRECT. In accordance with P-1, Containment pressure;;::
| |
| 4 psig as read on PT-945, -947, -949, at a coincidence of 2/3, will result in an automatic actuation of Safety Injection.
| |
| Steam Line Isolation signals are generated from Containment pressure instruments PT-946, -948, and -950; therefore, a Steam Line Isolation signal is NOT generated.
| |
| B. INCORRECT.
| |
| Incorrect since Safety Injection will receive an automatic actuation signal. Plausible since the second part is correct and both Safety Injection and Steam Line Isolation actuation signals occur with a 2/3 coincidence and the candidate may believe that the even numbered CNMT pressure detectors provide the actuation signal for Steam Line Isolation and Safety Injection.
| |
| C. INCORRECT.
| |
| Incorrect since Steam Line Isolation signals for Containment high pressure ES-401 Sample Written Examination Question Worksheet Form ES-401-5 (18 psig) comes from PT-946, -948, and -950. Plausible since the Safety Injection actuation is correct and both Safety Injection and Steam Line Isolation actuation signals occur with a 2/3 coincidence and the candidate may believe that the odd numbered CNMT pressure detectors provide the actuation signal for Steam Line Isolation and Safety Injection.

| * A large Break LOCA has occurred RO 3 2.4.23 3.4 SRO
| |
| * The crew has transitioned to ES-1.3, TRANSFER TO COLD LEG RECIRCULATION, and are aligning the SI System for cold leg recirculation
| |
| * The STA reports Critical Safety Function Status Trees (CSFSTs) are as follows: o Containment
| |
| -YELLOW o Core Cooling -ORANGE o Heat Sink -RED o Integrity
| |
| -RED o Inventory
| |
| -YELLOW o Subcriticality
| |
| -GREEN Which ONE of the following identifies the crew response and the basis for this response?
| |
| A. Transition to FR-C.2, RESPONSE TO DEGRADED CORE COOLING, to preclude an extreme challenge to the Core Cooling CSFST. B. Transition to FR-P.1, RESPONSE TO IMMINENT PRESSURIZED THERMAL SHOCK CONDITION, to ensure reactor vessel integrity is maintained.
| |
| C. Transition to FR-H.1, RESPONSE TO LOSS OF SECONDARY HEAT SINK, to establish Auxiliary Feedwater as a means of restoring core cooling. D. No transition required, continue performing ES-1.3 to ensure a source of water is aligned to provide core cooling. Answer: D ES-401 Explanation (Optional):
| |
| Sample Written Examination Question Worksheet Form ES-401-5 A. INCORRECT.
| |
| Plausible because the basis for transitioning to FR-C.2 is correct. Incorrect because ES-1.3 contains a NOTE prior to step 3 that precludes transitioning to FR Procedures until after step 12 is complete.
| |
| Also, FR-C.2 contains a CAUTION prior to step 13 "The following step will cause SI Accumulator injection which may result in a RED path condition in F-0.4, Integrity Status Tree." This procedure should be completed before transition to FR-P.1, Response to Imminent Pressurized Thermal Shock." B. INCORRECT.
| |
| Plausible because a RED condition on the Integrity CSFST would require a transition to FR-P.1; however, ES-1.3 contains a NOTE prior to step 3 that precludes transitioning to FR Procedures until after step 12 is complete.
| |
| C. INCORRECT.
| |
| Plausible because FR-H.1 is the most urgent FR Procedure with the given conditions and would be transitioned to in most cases during the EOPs. Incorrect because ES-1.3 contains a NOTE prior to step 3 that precludes transitioning to FR Procedures until after step 12 is complete.
| |
| D. CORRECT. In accordance with ES-1.3, NOTE prior to step 3 "Steps 3 through 12 should be performed without delay. FR procedures should not be implemented prior to completion of these steps." ES-1.3 Background Document states "A suction source of water for the SI pumps must be maintained to provide core cooling.

| |
| Sample Written Examination Question Worksheet Form ES-401-5 A. INCORRECT.
| |
| Plausible because first part is correct. Second part is incorrect as SIG pressure will rise with T AVG which will go to ARV setpoint in this plant condition, 1050 psig. This will cause lower Auxiliary Feedwater flow. The second part is plausible since AFW flows are relatively stable post-trip with no extenuating events. B. CORRECT. Following the reactor trip and safety injection, both MDAFW Pumps started and their respective discharge valve fully opened and then throttled back to approximately 215 gpm. Since 'B' MSIV was not closed for 2 minutes, 'B' SIG pressure was much lower than 'A' SIG pressure when the MDAFW Pumps started and the discharge valves automatically throttled.
| |
| Once 'B' MSIV was closed, the pressure in 'B' SIG started to rise resulting in 'B' MDAFW Pump flow to lower (with no operator actions).
| |
| As RCS TAvG continues to rise back to no-load value, the pressure in the S/Gs will rise and stabilize at the ARV setpoints (1050 psig). With no operator actions, MDAFW Pump flow will lower and stabilize at a new lower value due to pumping to a higher pressure S/G. C. INCORRECT.
| |
| Plausible if candidate does not know that MDAFW Pump throttle back is a one-time event following pump start and will throttle back to current Steam Generator pressure.
| |
| Second part is incorrect as S/G pressure will rise with T AVG which will go to ARV setpoint in this plant condition, 1050 psig. This will cause lower Auxiliary Feedwater flow. The second part is plausible since AFW flows are relatively stable post-trip with no extenuating events. D. INCORRECT.

| |
| Sample Written Examination Question Worksheet Form ES-401-5 A. CORRECT. In accordance with P-12 a loss of Offsite Power Circuit 7T, with 'A' EOG failure, will result in Bus 14 being de-energized which causes Instrument Bus 'B' losing power. This will cause a loss of Power Range Nuclear Instrument N-42. Loss of the second PRNI will cause Permissive P-10 to de-energize resulting in a block of Source Range High Voltage, de-energizing both SRNls. B. INCORRECT.
| |
| Plausible since the first part is correct and the candidate may believe that only one Source Range Instrument is required since a majority of safety systems utilize a redundant instrument/component scheme where only half the instruments/components are required.
| |
| Also, the audible count instrument is powered from Instrument Bus 'D' which remains energized in this event.
