| |
| : 1. Procedure Step: 2.4 FPC Attachment 5 ESTIMATED TIME-to-200°F for Critical step spent FUEL POOL NOTE 1 - The 72 hour mark on the curves is utilized by Procedure 0. PROTECT-EQP during on-line periods when the time for SFP to reach 200°F upon loss of normal cooling is < 72 hours. This is performed to develop protection of systems and equipment required to maintain the functions of spent fuel pool decay heat removal and inventory control.
| |
| NOTE 2 - If fuel pool temperature falls between curves, use next highest temperature curve.
| |
| Standard Examinee reviewed the notes. Examinee understands that if the temperature is between the temperature lines not to interpolate and that the higher temperature line is used.

| |
| : 3. Procedure Step: 2. Assumptions of Figure 2, Figure 3, Figure 4, and Figure 5 (reference NEDC 11-080, SFP Heatup to 200°F; Revision 3).
| |
| NOTE - These graphs are based on conservative estimates and are intended to give initial estimates.
| |
| Actual temperature trending will provide more accurate time estimates and can override these curves.
| |
| 2.1 Figure 2 and Figure 3 are post RE-30 to determine Fuel Pool Heatup rate considering the expected discharge from the reactor for 30 days after refueling shutdown to 800 days.
| |
| 2.2 Figure 4 and Figure 5 are post RE-30 for the period of 30 days after refueling shutdown to 800 days for spent fuel pool temperatures between 70°F and 190°F.
| |
| 2.3 Figure 4 and Figure 5 assumes a full core off-load occurring 60 days after RE-30 shutdown to 800 days over a range of spent fuel pool temperatures between 70°F and 190°F. Even though they utilize decay heat of 60 days operation as a design assumption, they may be utilized any time after startup from refueling outage.
| |
| 2.3.1 Data shows relative stability in heat input (from decay) from off-loaded core after 60 days full power operation.
| |
| NOTE - Although Attachment 2 actions will have FPC pumps running, these graphs remain conservative and are to be utilized.
| |
| 2.4 No FPC pumps running.
| |
| 2.5 Gates Closed/In.
| |
| 2.6 All decay heat removal and inventory makeup methods have been lost.
| |
| | |
| CNS NRC Exam 2020-9 JPM A1 Page 8 of 13 Standard Examinee determined that step 2.2. was the applicable step to know to use Figure 4 to determine time to 200°F and the rest of the conditions required were given in the Initial Conditions and Cues.

| | |
| ==SUMMARY==
| |
| | |
| The plant is operating at 95% power near the end of the operating cycle.
| |
| After the crew takes the watch, the BOP will shift REC pumps from A in operation to B in operation IAW Procedure 2.2.65.1. The CRS will enter LCO 3.7.3 Condition B for this evolution due to manipulation of REC pump mode select switches.
| |
| After REC pumps have been shifted, the crew will raise power with Reactor Recirculation. When power reaches 100%, a minor earthquake will occur. This will cause the running gland steam exhauster to trip. The crew will take alarm card actions and start the standby gland steam exhauster. The earthquake also causes failure of the Division 1 drywell H2/O2 analyzer. The CRS will enter TLCO 3.3.3 Condition B for the inoperable H2/O2 analyzer.
| |
| After response to the earthquake is complete and the TRM requirements have been addressed for the H2/O2 analyzer, RFPT A governor valve will gradually fail open, resulting in RFPT A speed and reactor water level rising and a RFPT A control trouble alarm. The crew will enter Procedure 2.4RXLVL. RFPT B speed will lower automatically in response to rising reactor water level. The crew will diagnose RFPT A is not responding properly to its control signal and will trip RFPT A IAW the alarm card and enter Procedure 2.4MC-RF.
| |
| After the crew has stabilized plant conditions, Feedwater line B will rupture in the drywell. An automatic scram will occur on high drywell pressure. The crew will enter EOP-1A and EOP-3A on high drywell pressure. Five control rods will fail to insert on the scram, and the crew will transition from EOP-1A to EOP-6A and EOP-7A. Reactor power will be 0%.
| |
| Reactor water level will promptly fall to approximately -50 inches wide range, then it will slowly lower. The crew will re-enter Procedure 2.4MC-RF and secure Feedwater and Condensate. The crew will secure HPCI since it injects into the broken FW line. RCIC will fail to automatically start on low reactor water level, and when the crew attempts to start it manually, RCIC injection valve RCIC-MO-21 will fail closed. Elevated drywell pressure will require operation of Torus and drywell sprays.
| |
| The crew will begin inserting SRMs and IRMs following the scram, but an intermittent failure of the drive control switch will require a second attempt to fully insert SRMs/IRMs. The crew will attempt to insert the five control rods that failed to scram using RMCS, but will only be successful in inserting one of the five rods, requiring the crew to continue ATWS strategies. The crew will inhibit ADS to prevent uncontrolled depressurization and cold water injection (CT#1).
| |
| Page 5 of 46 Rev 1
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 1 Page 6 of 46 Reactor water level will continue to slowly lower to -183 inches Corrected Fuel Zone, and emergency depressurization will be required IAW EOP-7A/6B. The crew will stop and prevent all available injection systems except boron and CRD (CT#2), then the crew will emergency depressurize using SRVs. When reactor pressure lowers to the Minimum Steam Cooling Pressure, 145 psig, the crew will restore reactor water level to +3 inches to +54 inches using RHR.
| |
| The exercise ends when emergency depressurization is complete and level is being restored to +3 inches to +54 inches.

| |
| In order to effect a reduction in reactor power, actions in Contingency #5 may deliberately lower RPV water level to a level below the automatic initiation setpoint of ADS. Actuation of this system imposes a severe thermal transient on the RPV and complicates the efforts to maintain RPV water level within the ranges specified in Contingency #5. Further, rapid and uncontrolled injection of large amounts of relatively cold, unborated water from low pressure injection systems may occur as RPV pressure decreases to and below the shutoff heads of these pumps. Such an occurrence would quickly Safety Significance dilute in-core boron concentration and reduce reactor coolant temperature. When the reactor is not shutdown, or when the shutdown margin is small, sufficient positive reactivity might be added in this way to cause a reactor power excursion large enough to severely damage the core. Therefore, ADS initiation is purposely prevented as the first action of the level/power control procedure. When required, explicit direction to depressurize the RPV is provided in the PSTG, thereby negating any requirement to maintain the automatic initiation capability of ADS.

Inhibiting chosen performance ADS before the Tech Spec cooldown limit is exceeded limit ensures the RPV fission product barrier is not challenged by a significant thermal transient.
| |
| BWR Owners Group App. B, step RC/Q-6 Appendix The scenario must be designed to make the crew lower RPV level per EOP-7A step FS/L-6 or FS/L-7 (i.e. ATWS with Scenario Guide power >3% following trip of both recirc pumps, and Requirements Feedwater or HPCI maintaining level above -60 CFZ).

| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 1 Page 9 of 46 When Emergency Depressurization is required during a failure to scram condition, stop and prevent all injection into the RPV except for RCIC, Boron Injection, and CRD prior to opening an SRV for emergency depressurization.
| |
| Critical Task #2 (Failure to fully stop and prevent a subsystem IAW the hard card before an SRV is opened does not constitute failure of this CT if the subsystem is subsequently aligned such that it does not inject during depressurization.)
| |
| Injection into the RPV is terminated and prevented while emergency RPV depressurization proceeds, in order to prevent uncontrolled injection of large amounts of cold water as RPV pressure decreases below the shutoff head of operating system pumps. Injection from boron injection systems and CRD is not terminated because operation of these systems may be needed to establish and maintain Safety Significance reactor shutdown. Further, the injection flowrates from these systems are small compared to those of the other systems used to control RPV water level. Injection from RCIC is not terminated because the injection flowrate from this system is small, continued operation of the turbine aids in depressurizing the RPV, and operation during RPV depressurization is not expected to result in significant injection flowrate variations.
| |
| Cues Emergency Depressurization is required by EOP-3A, EOP-5A, or EOP-7A during a failure to scram event with power above 3%. EOP-7A step FS/L-15 is required.

| |
| | |
| ==SUMMARY==
| |
| | |
| The plant is operating at 100% power near the end of the operating cycle.
| |
| After the crew takes the watch, the BOP will perform Procedure 15.TG.304, Main Turbine DEH High Pressure Fluid System Functional Test.
| |
| After procedure 15.TG.304 is completed, RCIC will spuriously initiate. The crew will enter Procedure 2.4CSCS and secure RCIC. RCIC injection must be secured or reactor power must be lowered to prevent exceeding the licensed power limit (CT#1). The CRS will enter TS 3.5.3 Condition A due to RCIC initiation capability being prevented.
| |
| After TS for RCIC have been addressed, APRMs A and C will fail. APRM A will spike high then fail to 0%. APRM A will spike high then fail to ~82%. The crew will respond IAW alarm cards, bypassing APRM C and resetting the RPS A half scram . The CRS will enter TS 3.3.1.1 Condition A.
| |
| After TS for APRM A and C have been addressed, a small leak from Reactor Recirc loop B will develop. The crew will enter procedure 2.4PC and vent primary containment.
| |
| After primary containment venting has stabilized drywell pressure, Recirc loop B will rupture. Drywell pressure and temperature will rise, requiring a manual scram. EOPs 1A and 3A will be entered due to high drywell pressure. RPV water level will lower due to the leak. HPCI Auxiliary Oil Pump (AOP) will develop an oil leak, and the HPCI AOP will be secured by the crew, preventing HPCI operation. CRD and SLC will not be able to keep up with the leak. RPV water level will continue to fall to TAF, -158.
| |
| Shortly after the scram, a loss of offsite power will occur. DG2 output breaker will fail to automatically close, and the crew will close it manually from Panel C (CT#2) to energize Div 2 low pressure ECCS systems. Elevated drywell pressure will require operation of Torus/Drywell Spray using systems not required to maintain adequate core cooling. CRD flow will be maximized and SLC will be initiated for level control, but they will not be able to stabilize reactor water level. When level reaches TAF, as indicated on SPDS using Corrected Fuel Zone (CFZ) at -158, and with Core Spray Pump B and LPCI Pumps C and D lined up for injection, the crew will enter EOP-2A and conduct emergency depressurization due to RPV water level below TAF and cannot be restored and maintained above -183 CFZ (CT#3).
| |
| When reactor press lowers below the low pressure permissive for LPCI injection valves, RHR-MO-25A will lose power. The crew will align RHR loop A to containment spray or suppression pool cooling, since RHR Pumps A and C will Page 6 of 40 Rev 1
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 1 Page 7 of 40 be operating on minimum flow. The crew will use Core Spray Pump B and RHR Pumps B and D to restore reactor water level.
| |
| The exercise ends when emergency depressurization is complete and reactor water level is being raised to the normal band, +3 to +54 inches.

| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 1 Page 8 of 40 CRITICAL TASK BASIS When a spurious RCIC initiation occurs that would cause power to rise above 100% rated thermal power, crew lowers power to restore and maintain power 100% rated Critical Task #1 thermal power by lowering Reactor Recirc flow before PMIS point NSSRP640 exceeds 2419 MWt.
| |
| License Condition C.1 states 2419 MWt is the Maximum Power Level authorized. The licensed 100% power limit is a basis for assumptions in the plants safety analysis.
| |
| Sustained operation above 2419 MWt may place unit Safety Significance operation outside of the plant design basis. NUREG 1021 App. D, section D states a CT must be essential to safety, and lists actions to for which operation or correct performance prevents violation of a facility license condition as one example of a CT.
| |
| Cues Annunciators 9-4-1/A-1, RCIC Logic Initiated, RCIC turbine speed rising, RCIC-MO-21 opening, RCIC flow on RCIC-FI-91 rising, Reactor power rising indicated on IRM/APRM recorders NM-NR-46A-D, SPDS, PMIS.
| |
| Operator depresses RCIC Turbine Trip button and closes RCIC-MO-131 on panel 9-4, AND/OR Measurable Performance If reactor power rises above 100%, Operator Selects S on Indicators RR flow controllers RRFC-SIC-16A(B) on panel 9-4 and lowers RR pump flow (by turning speed demand counter-clockwise on one speed controller at a time) until power stabilizes below 100% on IRM/APRM recorders NM-NR-46A-D.
| |
| Reactor power stabilizes below 100% on IRM/APRM Performance recorders NM-NR-46A-D and on PMIS points NSSRP640, Feedback NSSRP641, NSSRP642, NSSRP643, and NSSRP645.
| |
| Applicability Any time a cold water injection from RCIC causes FW temperature to lower such that reactor power would exceed 100% with no operator intervention.
| |
| License Condition C.1 lists 2419 MWt as the Maximum Power Level for CNS. Procedure 2.1.10, Station Power Changes, sections 10 and 11 describes the methodology for adherence to this limit. A note at step 11.1 states Minor power fluctuations due to automatic control system response, Justification for the random processes such as bi-stable flow, and flow meter chosen performance measurement uncertainties are inherent to BWR operating limit characteristics. Small, short-term fluctuations in power that are not under the direct control of a Licensed Reactor Operator are not considered intentional. Step 11.1 states It is prohibited to intentionally operate greater than the applicable licensed power limit as determined in Section 10. If core Page 8 of 40 Rev 1
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 1 Page 9 of 40 thermal power 1 hour average calculation exceeds applicable licensed power limit, action shall be taken to ensure subsequent hourly average remains less than or equal to applicable limit. Step 11.4 directs monitoring and maintaining PMIS Point NSSRP643 (running 1 hour average) and PMIS Point NSSRP645 (running 8 hour average) below 2419 MWt.
| |
| The 8 hour point is the legal record for plant power level.
| |
| PMIS point NSSRP640 (15 minute average) was chosen because it is more limiting and provides the most rapid update to core thermal power available.
| |
| BWR Owners Group N/A Appendix Initial power level must be near 100% so injection from RCIC Scenario Guide would cause reactor power to rise above 100% with no Requirements operator intervention.

| |
| 183 CFZ (TAF)
| |
| Failure to recognize the failure of DG2 output breaker to automatically close and energize the safety bus and failure to take manual action per Procedure 5.3EMPWR will result in Safety Significance unavailability of safety-related equipment necessary to provide adequate core cooling, otherwise resulting in core damage and a large offsite release.

| |
| This is only applicable if manual action from the Control Room would be effective in energizing the bus.
| |
| Attempting to energize ECCS systems must be performed to determine their availability by the time -183 is reached in order to properly implement EOP-1A decision steps regarding Justification for the restoring and maintaining RPV level. The MSCWL (-183 chosen performance CFZ) is the lowest RPV water level at which the covered limit portion of the reactor core will generate sufficient steam to preclude any clad temperature in the uncovered portion of the core from exceeding 1500°F.

(Momentary shrink below -183 CFZ due to automatic SRV operation in Low-Low Set mode does not constitute failure of this CT.)
| |
| The MSCWL is the lowest RPV water level at which the covered portion of the reactor core will generate sufficient steam to preclude any clad temperature in the uncovered Safety Significance portion of the core from exceeding 1500°F. When water level decreases below MSCWL with injection, clad temperatures may exceed 1500°F.
| |
| Cues Corrected Fuel Zone indication (SPDS) falls to -158 and lowering trend continues, and, before -158 CFZ is reached, initial conditions, field reports, and control room indications convey that adequate high pressure injection cannot be restored before level falls below -183 CFZ.

| |
| Emergency depressurization is allowed when level goes Justification for the below TAF (-158 CFZ) and should be performed, if in the chosen performance judgment of the CRS, level cannot be maintained above -183 limit CFZ. Since it is intended for the scenario supporting this CT to, early in the event, clearly indicate no high pressure injection systems can be made available to reverse the lowering level trend, the crew will have time to communicate and open 6 SRVs before -183 CFZ.
| |
| BWR Owners Group App. B, Contingency#1 Appendix LOCA severity should result in a near linear RPV level reduction that causes level to fall to TAF over approximately 15-20 minutes from the time the initial LOCA signal is received. It is very important to design the scenario such that the crew has information early during the LOCA event to determine high pressure injection systems cannot be recovered or optimized in order to stabilize level before -183 Scenario Guide CFZ is reached. The crew should know this within Requirements approximately 10 minutes from the start of the LOCA and by the time level lowers to -100 CFZ to allow time to align/realign low pressure systems for injection before level reaches -158 CFZ, so that the only remaining action when TAF is reached will be to conduct emergency depressurization.

| | |
| ==SUMMARY==
| |
| | |
| The plant is operating at 5% power during startup, beginning of life.
| |
| After the crew takes the watch, the ATC will withdraw control rods IAW the startup rod sequence to establish Bypass valves 17% open.
| |
| During the power ascension, SRM D will fail upscale. The crew will respond IAW the alarm card and bypass SRM D.
| |
| After Bypass valves are at least 17% open, the crew will align HPCI to standby IAW procedure 2.2.33. When HPCI-MO-15 is being opened, it will lose power.
| |
| The CRS will enter TS 3.6.1.3 Condition A and TS 3.5.1 Condition C. The crew will isolate HPCI steam supply.
| |
| After TS for HPCI-MO-15 have been addressed, CRD-FCV-19A will fail closed.
| |
| The crew will enter procedure 2.4CRD and shift CRD flow control valves.
| |
| After CRD flow control valves have been shifted, RPS B EPA breaker 1B2 will trip, resulting in a half scram, half PCIS Group 1, 2, 3, 7 isolations, and a full PCIS Group 6 isolation. RWCU will isolate and the pump will trip. The crew will transfer RPS B to its alternate supply per alarm card C-1/F-2, reset the Div 2 half scram IAW 2.1.5, and enter 2.1.22 to begin recovery from group isolations.
| |
| SGT B exhaust fan will trip after it automatically starts. The CRS will enter TS 3.6.4.3 Condition A for SGT B. The crew will not be given time to complete all of the actions of 2.1.22, such as restoring Reactor Building HVAC realignments, due to the timing of the scenario.
| |
| When response to the loss of RPS B is complete, a small RCIC steam line break will occur in the Reactor Building. Secondary containment area temperatures will rise, requiring entry into EOP-5A. If RCIC area temperatures reach 195°F, MSO limit and isolation setpoint, before the crew attempts manual isolation of RCIC steam supply valves, the automatic isolation will fail to occur.
| |
| When the crew attempts manual isolation of the RCIC steam supply valves, both valves will fail to fully close due to mechanical binding in their gear boxes.
| |
| EOP-1A entry and reactor shutdown will be required before two areas exceed the MSO limit (CT#1).
| |
| Following the scram, 480V Bus 1A will lose power. The crew will respond IAW procedure 5.3AC480 and will be required to start TEC Pump C.
| |
| When the crew has stabilized the plant following the scram, the RCIC steam leak will get worse, causing area temperatures in more than one area of the Reactor Building to approach the MSO limit. When two areas have reached the MSO limit, emergency depressurization will be required IAW EOP-5A, and
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 3 Page 6 of 40 the crew will enter EOP-2A to perform emergency depressurization (CT#2).
| |
| The crew may anticipate emergency depressurization and fully open Bypass valves, which also satisfies CT#2.
| |
| The exercise ends when the reactor has been depressurized and RPV water level is being restored to between +3 and +54 inches.
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 3 Page 7 of 40 CRITICAL TASK BASIS When a primary system is discharging into the secondary containment through a break and cannot be isolated, the crew scrams the reactor prior to reaching Maximum Safe Operating Critical Task #1 Temperatures in two areas. (For this scenario, RCIC-TE-77C Torus 890 ENE is the first area to exceed MSO and RHR-TE-99C Torus 885 NNW is the second area to exceed MSO.)
| |
| EOP-5A directs entering the RPV Control guideline and scramming the reactor when a maximum safe operating value is approached or exceeded. Failing to do so can result in an unnecessary offsite release and endanger plant personnel. Entering the RPV Control Safety Significance guideline shuts down the reactor and allows controlled RPV pressure reduction to lower the driving head of the leak to reduce the effect on secondary containment, in order to avoid or anticipate emergency RPV depressurization..
| |
| Cues Indication of rising or Maximum Operating values in an area of a system which is connected to the RCS, combined with abnormal system parameters (e.g. such as levels, pressures, and flow rates).
| |
| Field reports of visible/audible leaks into secondary containment.
| |
| Measurable Performance Operator depresses both manual scram pushbuttons, or places the Indicators Reactor Mode Switch to SHUTDOWN on panel 9-5.
| |
| RPS Group lights de-energized on panel 9-5.
| |
| Performance Feedback Control Rod full -in indication on panel 9-5.
| |
| Reactor power trend on nuclear instrumentation on panel 9-5.
| |
| Applicability EOP-5A conditions where a system (primary or non-primary) is discharging into the secondary containment and manual isolation capability from the control room is possible. This includes manipulation of valve control switches and valve power supply control switches, as applicable. If the leaking system is required for adequate core cooling (or meets the other criteria in EOP-05A), this task is not applicable.
| |
| EOP-5A directs that this action be taken when a maximum safe operating value is approached or exceeded and the source of a discharge cannot be isolated or determined. If temperatures, radiation levels, or area water levels in any one of the areas listed in the Secondary Containment Control guideline approach their maximum safe operating value, adequate core cooling, containment integrity, safety of personnel, or continued operability of equipment required to perform EPG actions can no longer be assured. A reactor scram is initiated through entry of the RPV Control guideline Justification for the to reduce the primary system discharge into secondary containment chosen performance limit and in anticipation of possible emergency RPV depressurization.
| |
| The scram is effected indirectly, through entry of the RPV Control guideline, rather than through an explicit direction in the Secondary Containment Control guideline, to ensure that RPV water level, RPV pressure, and reactor power are properly coordinated following the scram and to avoid potential conflicts with alternate rod insertion strategies in Step RC/Q if the RPV Control guideline is already in use. Failing to do so can significantly change the mitigation strategy as an unnecessary release will result and possibly endangering plant personnel.
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 3 Page 8 of 40 Before reaching two Maximum Safe values in two areas for the same parameter was chosen because that is the next EOP-5A significant action threshold, when Emergency Depressurization is required. Shutting down the reactor and entering the RPV Control guideline before reaching this level may avert the significant thermal transient on the RPV caused by Emergency Depressurization. If BWR Owners Group emergency depressurization is ultimately required, first shutting Appendix down the reactor reduces the amount of energy introduced into secondary containment, thus mitigating the effects on secondary containment temperature, radiation, and water levels, as well as offsite release rates. Emergency depressurization without reactor shutdown creates an unnecessary challenge to the secondary containment barrier.

| Appendix D Scenario Outline Form ES-D-1 NRC CNS 2020-09 Scenario 3 Page 9 of 40 When a primary system is discharging into the secondary containment through an unisolable break, the crew Emergency Depressurizes by opening 6 SRVs when maximum safe operating temperatures are exceeded in two areas and prior to exceeding Maximum Safe Operating temperature in a third area. (For this scenario, RCIC-TE-77C Torus 890 ENE and Critical Task #2 RHR-TE-99C Torus 885 NNW are the two areas that will exceed MSO first. RWCU-TE-117F Torus 896 W would be the third area to exceed MSO.) Anticipating Emergency Depressurization and fully opening Bypass valves also satisfies this CT.
| |
| Should secondary containment parameters exceed their maximum safe operating values in more than one area, the RPV must be depressurized to preclude further degradation. RPV depressurization places the primary system in its lowest possible energy state, rejects heat to the suppression pool in preference to outside the containment, and reduces the driving head and flow of primary systems that are unisolated and discharging into the Safety Significance secondary containment.
| |
| The criteria of "two or more areas" specified identifies the rise in secondary containment parameters as a wide-spread problem which may pose a direct and immediate threat to secondary containment integrity, equipment located in the secondary containment, and continued safe operation of the plant.
| |
| Cues SPDS indication for secondary containment parameters indicate area radiation, area temperature, or area water level has exceeded its maximum safe operating value in two areas.

| |
| SRV-71A SRV-71B SRV-71E Measurable Performance SRV-71G Indicators SRV-71H SRV-71C SRV-71D SRV-71F Crew will observe SRV light indication go from green to red, amber pressure switch lights illuminate, reactor pressure lowering on Performance Feedback SPDS and panel 9-3 and 9-5 meters and recorders, and SRV tailpipe temperatures rise on recorder MS-TR-166.
| |
| Applicability EOP-5A conditions, RCS leaks into secondary containment with the RPV pressurized.
| |
| Emergency Depressurization is required due to effects of a break spreading into and potentially affecting safety equipment and operations in more than one area; however, emergency Justification for the depressurization is not allowed until the second area exceeds its chosen performance limit Max Safe limit. Before the Max Safe limit is exceeded in a third area gives reasonable time for the crew to perform emergency depressurization before the leak hampers equipment or operations in an even more widespread area.

| |
| Appendix The scenario must be able to drive the selected parameter to its Max Safe value in three plant areas. If temperature is chosen, a failure to scram event, where RPV pressure is not allowed to be lowered, is well suited. Also, ensure the leak severity itself, or subsequent cold water injection, does not deplete RPV pressure Scenario Guide (driving head) so low that Max Safe in a third area cannot be Requirements reached. The crew should be driven to ED, versus just reducing pressure, to provide a consistent, measurable performance indicator. The CT listed in the scenario should list which instruments/areas will exceed their MSO limit first, second, and third.

(For this scenario, RCIC-TE-77C Torus 890 ENE and RHR-TE-99C Torus 885 NNW are the two areas that will exceed MSO first. RWCU-TE-117F Torus 896 W would be the third area to exceed MSO.) Anticipating Emergency Depressurization and fully opening Bypass valves also satisfies this CT.

| ==SUMMARY==
| |
| | |
| The plant is operating at 100% power near the middle of the operating cycle.
| |
| After the crew takes the watch, the BOP will begin placing RHR Pump B in Suppression Pool Cooling IAW Procedure 2.2.69.3. When the operator attempts to open RHR-MO-34B, its breaker will immediately trip. RHR Pump B, operating on minimum flow, must be secured within 15 minutes. The CRS will enter TS 3.6.2.3 Condition A.
| |
| After TS for RHR-MO-34B have been addressed, CRD Pump A will trip. The crew will respond IAW the alarm card and place CRD Pump B in service.
| |
| After CRD Pump B has been placed into service, Reactor Building Exhaust Fan 1A trips and Fan 1B will not start. Secondary Containment pressure will rise, requiring entry into EOP-5A and TS 3.6.4.1. The crew must enter 2.4HVAC to restore Reactor Building negative pressure with SGT.
| |
| After response to loss of RB ventilation is complete, three control rods will simultaneously drift in. The crew will respond IAW the alarm card and insert a manual scram. RPS will de-energize, but the scram air header will fail to vent.
| |
| Manual initiation of ARI will fail. The crew will enter EOP-1A and transition to EOP-6A and EOP-7A. The crew will trip Recirc pumps. Power will be approximately 50%. The crew will install MSIV low level isolation bypass jumpers (CT#1) and inhibit ADS (CT#2) and lower reactor water level IAW EOP-7A to control power. When reactor water level is lowered and RCIC automatically initiates, its speed controller will fail low in automatic, and the crew will raise RCIC speed in MANUAL.
| |
| CRD Pump B will trip, preventing manual control rod insertion. Both SLC pumps will trip after they have been started. The crew must direct the building operator to manually vent the scram air header IAW procedure 5.8.3 (CT#3). If the crew has not manually vented the scram air header, the main turbine will spuriously trip 25 minutes following the scram, resulting in SRVs opening.
| |
| After the scram air header has been vented and all control rods have fully inserted, the crew will transition to EOP-1A and stabilize plant conditions. The exercise ends when all control rods are inserted and reactor water level is being raised to the normal band, +3 to +54 inches.

| |
| If the MSLs isolate with power >30%, SRV operation is required to control RPV pressure. If the reactor is still generating appreciable power, the Heat Capacity Temperature Limit could then be reached in a relatively short time. Exceeding HCTL would challenge primary containment Safety Significance integrity, especially during ATWS conditions, and would require emergency depressurization. Step C5-2 therefore defeats certain main steam line isolations to prevent closure of the MSIVs and permit continued use of the main condenser as a heat sink, even if RPV water level must be lowered below the low level isolation setpoint.

| |
| In order to effect a reduction in reactor power, actions in Contingency #5 may deliberately lower RPV water level to a level below the automatic initiation setpoint of ADS. Actuation of this system imposes a severe thermal transient on the RPV and complicates the efforts to maintain RPV water level within the ranges specified in Contingency #5. Further, rapid and uncontrolled injection of large amounts of relatively cold, unborated water from low pressure injection systems may occur as RPV pressure decreases to and below the shutoff heads of these pumps. Such an occurrence would quickly Safety Significance dilute in-core boron concentration and reduce reactor coolant temperature. When the reactor is not shutdown, or when the shutdown margin is small, sufficient positive reactivity might be added in this way to cause a reactor power excursion large enough to severely damage the core. Therefore, ADS initiation is purposely prevented as the first action of the level/power control procedure. When required, explicit direction to depressurize the RPV is provided in the PSTG, thereby negating any requirement to maintain the automatic initiation capability of ADS.

| |
| Failure to effect shutdown of the reactor when a RPS setting has been exceeded would unnecessarily extend the level of degradation of the safety of the plant. This could further degrade into damage to the principle fission product barriers if left unmitigated. Action to shut down the reactor is required when RPS and control rod drive systems fail.

| * The highest suppression pool temperature at which initiation Safety Significance of boron injection will permit injection of the Hot Shutdown Boron Weight of boron before suppression pool temperature exceeds the Heat Capacity Temperature Limit.
| |
| * The suppression pool temperature at which a reactor scram is required by plant Technical Specifications.
| |
| The BIIT is a function of reactor power. If all control rods are inserted before suppression pool temperature reaches the BIIT, the HCTL will not be exceeded, so emergency RPV depressurization will be precluded.
