The scenario begins with Unit 1 at 30% power and Unit 2 at 100% power. A small leak on the suction isolation valve for B RWCU pump is being remotely monitored with video equipment in the Reactor Building. The startup is on hold and Extraction Steam will be removed from Feedwater Heater string C immediately after assuming the shift to allow Maintenance to replace a solenoid in panel 1C103.
A temperature sensor element failure in the main turbine lube oil control loop will cause an oil temperature increase resulting in manual operation of the service water temperature control valve to reduce and stabilize oil temperature. A control rod will drift in several notches; the crew will implement an off-normal procedure and fully insert the drifting rod while an investigation and recovery plan is made.
A loss of Reactor Building HVAC will result in a loss of Zone 1 dip and require the crew to implement an off-normal procedure. The Technical Specification for Secondary Containment integrity will not be met requiring entry into Condition A. In addition, the loss of Reactor Building HVAC will cause RWCU pump room temperatures to increase faster than normal due to the small steam leak.
A loss of main condenser vacuum will lead the crew to perform a manual reactor scram. RPS A does not trip when the mode switch is taken to shutdown and no control rods insert. The crew will implement actions for failure to scram and when either division 1 manual scram pushbutton is armed and depressed all control rods will fully insert. A loss of Feedwater occurs when the reactor mode switch is placed to shutdown forcing the crew to restore and maintain Reactor water level with RCIC. As condenser pressure
.___,continues to increase the MSIVs will automatically close and Reactor pressure will be controlled with SRVs.
When RClC is initiated a steam line break occurs in the RClC pump room. RClC room temperatures will increase to the auto isolation setpoint but the isolation valves fail to close and isolate the leakage. Manual isolation attempts will not be successful. The RWCU temperatures will also rise to the isolation setpoint uccessfully isolate either manually or automatically. At this point two secondary temperatures have exceeded maximum safe values and a primary system is discharging requiring the crew to perform Rapid Depressurization.
During Rapid Depressurization 2 ADS SRVs will fail to open requiring the crew to open additional SRVs until 6 valves are open to accomplish the blowdown. The scenario will be terminated after the Reactor is depressurized and actions are in progress to implement Suppression Pool Cooling.

- Recoqnize failure to scram and initiate a manual scram Safety Significance Control rod insertion initiates power reduction immediately.
Consequences for Failure to Perform Task Failure to insert control rods allows power to remain elevated with resultant power oscillations and potential core damage.
Indications/Cues for Event Requiring Critical Task Exceeding an RPS scram setting with NO reactor scram signal, or RPWARI fails to fully insert all control rods.
Performance Criteria Manually insert a reactor scram by arming and depressing the manual scram pushbuttons.
.*-- - Performance Feedback Successful insertion of control rods will be indicated by rod position full-in indication.
- Perform Rapid Depressurization when two Secondary Containment areas exceed max safe temperature Safety Significance A high-energy leak in the Secondary Containment area impacts the integrity of Secondary Containment. Failure of the Secondary Containment directly relates to the 10CFR100 design criteria of dose to the General Public.
Action is taken to isolate systems that are discharging into Secondary Containment to terminate possible sources of radioactivity release. Minimizing radioactive release to Secondary Containment also helps accomplish the objective of precluding a radioactive release outside Secondary Containment under conditions where Secondary Containment integrity cannot be maintained. Previous containment control actions have not, for whatever reason, mitigated the event and now potentially large areas of the Secondary Containment have been challenged.

CRITICAL TASKS Consequences for Failure to Perform Task Failure to take actions to mitigate the energy released to the Secondary Containment directly affects the radiation dose to the General Public.
scrr-9 WHEN RB AREA TEMP EXCEEDS MAX SAFE IN 2 OR MORE AREAS RAPID DEPRESS IS REQ'D Should Secondary Containment area temperatures/radiation/waterlevels continue to increase to their Max Safe values in more than one area with a primary system discharging into Secondary Containment, the RPV must be rapidly depressurized. Depressurizing the RPV promptly 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 un-isolated and discharging into the Secondary Containment.
The criteria of "2 or more areas" identifies the increase in temperature (radiation or water level) trend as a wide spread problem which may Fose a direct and immediate threat to Secondary
, Containment integrity, equipment located in the Secondary Containment, or continued safe operation of the plant.
IndicationslCues for Event Requiring Critical Task Increasing Steam Leak Detection System temperatures and alarms indicating levels at Max Safe values.
Performance Criteria Perform a Rapid Depressurization per EO-000-112 when two or more RB areas exceed max safe temperatures per EO-000-104 Table 8.
Initiate ADS / Manually Open all 6 ADS valves Performance Feedback Initiating a rapid depressurization causes Reactor pressure to lower which lowers the driving force of any primary system breach.
Verify ADS valves are open using red light indication, acoustic monitoring, lowering Reactor pressure and rising Reactor water level.

SUMMARY
The scenario begins with Unit Iin MODE 2 at 5% power and Unit 2 at 100% power. ESS Bus 1A202 is aligned to alternate; the crew will transfer bus 1A202 to its normal power source following routine breaker maintenance.
A Reactor Building steam tunnel leak detection instrument failure results in an isolation instrumentation channel failure for the MSIVs. Technical Specifications require declaring the instrument inoperable and taking the actions for Condition A. A high bearing temperature on Reactor Feedwater Pump A will require the crew to transfer feedwater injection to RFP B and shutdown or trip RFP A.
An upscale failure of IRM G will result in a half scram condition; the crew will bypass IRM G and recognize the bypass was unsuccessful preventing reset of the half scram condition.
A loss of offsite power (LOOP) will occur along with numerous onsite ESS bus and diesel generator failures that result in only one 4KV bus (1A202) being energized from the emergency diesel generator. A small recirculation system suction line break occurs inside the drywell along with the power loss. Following the automatic reactor scram and isolation one control rod fails to insert. The loss of power results in a loss of feedwater injection capability and HPCl injection is prevented by a steam supply valve failure. The only high pressure injection source is RCIC. Inventory loss from the break exceeds makeup capacity while reactor pressure remains above the discharge head of low pressure ECCS injection systems and reactor water level drops below TAF (-161). Logic failure will prevent automatic start of the B RHR pump. Control
--- room manual operation of the failed RHR pump will allow injection from B loop of RHR. The crew will perform Rapid Depressurization and permit low pressure ECCS injection from B RHR and CS pumps.
During reactor water level recovery an automatic trip of Core Spray pump B occurs and the crew will be unable to recover the pump. Following the reactor depressurization, when drywell instrument run temperatures exceed SAT curve limits, the US will declare reactor water level indeterminate and enter EO-000-114, RPV Flooding.
With only B RHR injection capacity flooding pressure can not be achieved. Maintenance assistance will allow recovery of emergency diesel generator D. A failure will prevent the automatic closure of breaker 1A20404 from the diesel generator to the bus. The crew can manually close breaker 1A20404 and provide RHR and Core Spray injection using the D pumps. The crew will maximize injection sources to establish RPV pressure 281 psig above Suppression Chamber pressure.
The scenario will be terminated when the crew has established RPV pressure 281 psig above Suppression Chamber pressure.

As many of these systems as necessary must be used to establish and maintain the conditions required to verify RPV flooding. Establishing adequate core cooling conditions dictates that adherence to Vortex limits not be required.
Three conditions must be satisfied to verify RPV flooding without direct indication of RPV water le vel:
I.At least 4 SRVs must be open. This ensures that adequate steam flow will exist for cooling any un-submerged portion of the core when RPVpressure is 2 81 psid above Suppression Chamber pressure.
.2. RPVpressure must not be decreasing. This ensures that the required steam flow will be maintained.
- 3. RPVpressure must be greater than Suppression Chamber pressure by at least 81 psid, the Minimum RPV Flooding Pressure (MRFP).
The MRFP is defined to be the lowest differential pressure between the RPV and the Suppression Chamber at which steam flow through 4 SRVs is sufficient to remove decay heat. The assumed decay heat generation rate is ten minutes after shutdown from full power. Since ten minutes is the earliest that RPV flooding could reasonably be expected to be needed, establishing and maintaining RPV pressure above the MRFP assures that more than enough steam flows through the SRVs to carry away all core decay heat.
This requires that a sufficient quantity of water reach the core to carry away decay heat by boiling, which in turn requires that RPV water level increase. Maintaining this above the minimum pressure (81 psid) assures that the RPV will ultimately flood to the main steam lines.

CRITICAL TASKS Performance Criteria Recognize failure of RPV level indicators due to reaching saturation conditions on the instrument runs, initiate rapid depressurization by opening ADS valves and then increasing RPV injection until RPV pressure is NOT decreasing and is 81 psig above Suppression Chamber pressure.
Performance Feedback Initiating a rapid depressurization causes Reactor pressure to lower to the shutoff head of the low pressure injection systems allowing water level to rise to the point that RPV pressure will increase to a value that is 81 psid above Suppression Chamber. At this point injection should be stabilized to maintain the DP.
Verify ADS valves are open using light red light indication, acoustic monitoring and lowering Reactor pressure.
Verify injection from available systems raises RPV pressure to a value that is 81 psid above Suppression Chamber.

SUMMARY
The scenario begins with Unit 1 at 90% power EOL and Unit 2 at 100% power EOL. 1B EHC pump is out of service for breaker maintenance. RHR loop A has just been secured from Suppression Pool cooling and 1A RHRSW pump is running for maintenance to record vibration data. The crew will shutdown 1A RHR SW pump.
Following shutdown of ? A RHRSW the RHRSW radiation monitor will fail upscale. The crew will direct Chemistry to obtain a grab sample of RHRSW to validate the indicated high radiation condition. The US will declare the RHRSW radiation detector inoperable and enter TR 3.11 .I .5.
The Stator Cooling TCV-10183 will fail closed causing a loss of Stator Cooling. Investigation will determine that the TCV is operating erratically and investigation/repairs is on going. Stator Cooling temperatures will increase and the crew will decrease generator load IAW Alarm Response ON-197-001.
Even with generator load reduced, Stator Cooling will continue to rise causing a Main Turbine Trip if the crew does not remove the unit from service before hand. A failure of RPS B to trip will result in an Electrical ATWS and all control rods will fail to insert. ARI will not properly actuate, further inhibiting control rod insertion. When the crew initiates SLC a failure of the squib valves to fire will prevent SLC injection. The crew will initiate action to inject boron with the RClC system and inhibit ADS. The crew will decrease core power by lowering RPV water level to c - 6 0 but > -161 using Feedwater. A loss of 1A EHC pump will result in a loss of EHC hydraulic fluid pressure causing the TBVs to close. SRV operation
. will raise Suppression Pool water temperature requiring the crew to enter the Primary Containment Control procedure and maximize Suppression Pool cooling. Actuation of SRVs will eventually cause Drywell pressure to increase > 1.72psig resulting in a loss of Condensate and Feedwater injection due to initiation of Plant Aux Load Shed circuitry. The crew will restore and maintain RPV water level with HPCl and RClC systems.
The crew will be unsuccessful at rod insertion by maximizing CRD and drifting control rods. Manually driving rods and venting the scram air header will be successful for rod insertion.
The scenario will be terminated when all control rods have been inserted and actions are in progress to maximize Suppression Pool cooling and restore RPV water level to +13to +54.

- Recognize failure to scram and iniect SLC and inhibit ADS Safety Significance Early boron injection has the following benefits:
Stop or prevent large magnitude Limit Cycle Oscillations which can lead to core damage.
Limit fuel damage from uneven flux patterns that could result from partial rod inserts.
Inhibiting ADS prevents uncontrolled injection of large amounts of relatively cold, unborated low pressure ECCS water when the reactor is not shutdown with control rods.
Consequences for Failure to Perform Task Failure to inject Boron can result in Cycle oscillations which can lead to core damage.
Fuel damage from uneven flux patterns that could result from partial rod inserts.
Failure to inhibit ADS can result in large amounts of positive reactivity addition due to boron dilution and cold water injection.
LQ/Q-3 IF INITIAL ATWS PWR > 5%
OR CANNOT BE DETERMINED INJECT SLC AND INHIBIT ADS When scram and ARi have failed, reactor power must be considered to determine if immediate boron injection is required. If initial ATWS power was greater than 5%, then a relatively large number of control rods have failed to insert. The seriousness of this condition requires immediate injection of boron to positively terminate the A 7WS event.
ADS initiation may result in the injection of large amounts of relatively cold, unborated water from low-pressure injection systems. With the reactor either critical or shutdown on boron, the positive reactivity addition due to boron dilution and temperature reduction through the injection of cold water may result in a reactor power excursion large enough to cause substantial core damage.
Preventing ADS is therefore appropriate whenever boron injection is required.

CRITICAL TASKS
- Lower RPV level to e -60 inches but > -161 inches Safety Significance Core damage due to unstable operation can be prevented or at least mitigated by promptly reducing feedwater flow so that level is lowered below the feedwater spargers.
Consequences for Failure to Perform Task A General Electric Company study (NEDO-32047) indicates that the major threat to fuel integrity from ATWS is caused by large-amplitude power/flow instabilities. These density-wave instabilities will most likely develop in the non-isolation ATWS where the feedwater system is still available for makeup to the RPV. In this event, the feedwater system maintains normal water level, but feedwater heating is lost due to tripping of the turbine. Without preheating of the feedwater, high levels of core-inlet subcooling develop which can drive the reactor into a highly unstable mode of operation. General Electric calculations indicate that power oscillations become large enough to cause melting of fuel in high-power bundles.
LQ/L-13 MAINTAIN LVL BETWEEN -60" AND -161" USING TABLE 15 SYSTEMS BYPASSING INTERLOCKS AS NECESSARY IAW ANY:
The purpose of this step is to uncover the feedwater spargers sufficiently to reduce core inlet subcooling.
In the non-isolation ATWS event, core damage due to unstable operation can be prevented or at least mitigated by promptly reducing feedwater flow so that level is lowered below the feedwater spargers. Once level drops below the sparger nozzles, which are located at -24': the feedwater is sprayed into a region occupied by saturated steam. Steam will then condense on the injected feedwater, and the coolant will be heated as it falls to the liquid surface within the downcomer.
Heating of the feedwater by steam condensation limits the buildup of core inlet subcooling and can prevent the onset of severe power/flow instabilities.
This step identifies the widest acceptable water level control band. Although level fluctuations within this band are safe, it is very desirable to maintain level within the more restrictive tarqet area of -1 10" to -60". The target area and expanded band are shown in Figure 8, Water Level Operation Guidance. The intent of this step is to remain within the target band at all times unless prohibited by system perturbations, and remain within the expanded band at all times.

--- CRITICAL TASKS Operation outside the target area has the following disadvantages:
The basis for an upper level of -60" is given above.
A lower level of -1 IO" is specified for the following reasons:
I. Provides a margin for core coverage.
- 3. Makes level control easier by maintaining level above the narrow region of the downcomer.
Below -1 10" the downcomer free area reduces from 300 to 88 e resulting in increased magnitude of indicated level oscillations.
- 4. Maintains sufficient core flow to carry liquid boron from lower plenum upward into the core.
As level is decreased below -1 IO, boron mixing efficiency is reduced because the natural circulation flow rate through the jet pumps is reduced and is not as efficient at carrying the injected boron from the lower plenum upward into the core.
At very low downcomer water levels near or below top of active fuel, there is little water available in the region above the jet pump throat for mixing with boron injected via RCIC. In this situation, there is concern that boron may accumulate in the stagnant region of the downcomer which is below the jet pump throat.
- 5. Water level can be determined from wide range level instrumentation.
- 6. Avoids MSlVisolation setpoint of -129".
RP V level below TAF is nof, by itself, a determination of whether or not level can be maintained
> -161". The determination that level cannot be maintained > -161" must be made based upon:
availability of high pressure injection systems, and, present level trend This decision must not be made prematurely since depressurization of a critical core results in destabilizing affects and has a potential to cause core damage.
Controlling reactor pressure, power and level with condensate and SRVs at 500 psig is difficult because all 3 parameters affect each other. Therefore, rapid depressurization is recommended when high pressure injection cannot be obtained.

\ ,
CRITICAL TASKS The initial influence of reactor depressurization is stabilizing since the additional flashing of liquid phase required for depressurization introduces excess voids in the reactor core which can essentially terminate the fission process if the rate of depressurization is high enough. Once the depressurization is complete, however, the result is the immediate initiation of power excursions.
Core damage is expected to occur from high clad stresses induced by: temperature excursions above the rewet temperature, PCI, cyclic fatigue, burnout or having the fuel enthalpy exceed the cladding failure threshold.
Indications/Cues for Event Requiring Critical Task ATWS with initial reactor power level greater than 5% APRM power Performance Criteria Lower reactor water level by manually controlling injection rate from Feedwater, HPCl and/or RCIC.
Preventing injection such as RCIC and HPCl as level drops below -30" and -38" respectively may be required when Feedwater is available.
The preferred systems for use in controlling RPV water level are those Table 75 Systems which inject into the feedwater sparger or outside the core shroud. These are used because cold water is
- preheated by steam and the flow path outside the core shroud mixes the relatively cold injected water with the warmer water in the lower plenum prior to reaching the core. Injection from SLC and CRD are always permitted during ATWS events. The operator throttles existing injection except CRD and SLC and prevents unwanted injection as necessary to decrease level.
Performance Feedback Lowering water level to -60 to -1 10 inches will result in power level lowering as indicated on the Average Power Range Monitors.

SCENARIO
SUMMARY
The scenario begins with Unit 1 at 80% power EOL and Unit 2 in MODE 4. 1B CRD pump is out of service for breaker maintenance. Condensate pump 1B has a possible ground; the crew will shutdown Condensate pump 1B for inspection. The crew will recognize the Condensate pump minimum flow recirc valve failed open and will manually close the valve to maintain proper condensate pump header pressure.
Following the shutdown of 1B Condensate pump the ANarrow Range Level instrument will fail upscale.
Feedwater level control system response will stabilize RPV water level at x +23 in automatic. The crew will implement an Off-Normal procedure to transfer RPV water level control from averaged level control to selected level control and return RPV water level control to automatic.
Following the water level perturbation a fuel clad failure will result in Turbine Building area high radiation and increasing main steam line radiation. The crew will respond by decreasing Reactor power. Radiation levels will continue to rise requiring the crew to manually scram the Reactor and manually close the MSlVs and MSL drains. When the mode switch is placed to shutdown a failure to scram will occur when RPS A fails to trip. The control rods will insert when the crew initiates ARI.
Following the scram a main steam line break will occur in the Turbine Building Steam Tunnel. The D MSL fails to isolate resulting in a sustained release to the Turbine Building. Release rates from the Turbine Building Vent Stack will increase above the ALERT level requiring entry into Radioactive Release Emergency Operating Procedure, EO-000-105. The crew will request performance of dose calculations
--.* and conduct a Reactor cooldown at < I OO°F/hr. When off-site dose calculations exceed the General Emergency level the crew will rapidly depressurize the Reactor.
The scenario will be terminated when the crew has performed a Rapid Depressurization and restored RPV water level to +13to +54.

CRITICAL TASKS It
- Recoqnize failure to scram and initiate ARI Safety Significance Initiation of ARI provides an independent and redundant means of depressurizing the reactor scram air header and operating the scram discharge volume vent and drain valves, causing rapid control rod insertion.
Rapid control rod insertion initiates an immediate power reduction and, in the case of a fuel clad failure, will quickly reduce the amount of radiation being released from the Reactor.
Consequences for Failure to Perform Task Failure to insert control rods allows power to remain elevated with continued release of radiation from the Reactor and also increases the potential for additional fuel damage.
Also, OP-AD-055, Operations Procedure Program, Section 9, defines Immediate Operator Actions as: Actions required immediately after the start of an event to stop the degradation of and mitigate the consequences of conditions that threaten fuel, RPV, or primary containment.. .. Attachment C of this procedure lists the following Immediate Operator Actions:
MSL RAD Increasing but e Reduce Reactor Power Trip Point (Fuel Clad e If Power Decrease did not stop RAD increase:
Failure) - Manually Scram Reactor AND
- Isolate MSlVs and MSL Drains Existing Scram Condition e PLACE Mode SW to S/D e OBSERVE all-rods-in e If More than 1 Rod > 00
- Arm and Depress Manual Scram PBs

CRITICAL TASKS IndicationslCuesfor Event Requiring Critical Task Manual insertion of an RPS scram with NO control rod motion.
Performance Criteria Insert control rods by manually initiating ARI.
Performance Feedback Successful insertion of control rods will be indicated by rod position full-in indication following manual initiation of ARI.
- Perform Rapid Depressurization before EPB proiected dose / dose rates reach General Emergency declaration criteria Safety Significance In order to minimize radiation exposure to the public, Rapid Depressurization of the RPV is required if a L-primary system is discharging and the radioactivity release rate cannot be controlled below the release rate that requires a General Emergency.
Consequences for Failure to Perform Task Failure to take the EOP actions will result in increased dose and/or dose rates at the EPB.
RR-6 BEFORE EPB PROJECTED DOSE/DOSE RATE REACHES GENERAL EMERGENCY DECLARATION CRITERIA RAPID DEPRESS IS REQ'D An offsite radioactivity release rate above the General Emergency action level represents a substantial increase in the severity of the offsite radioactivity release, relative to the entry condition, and accordingly presents a more immediate threat to the continued health and safety of the public.
Rapid depressurization is directed before the release rate reaches the General Emergency level to reduce the radioactivity release rate.

Page 9 Scenario ILO-302 Rev. 0, 2/9/2004 CRITICAL TASKS IndicationslCues for Event Requiring Critical Task Offsite radiation exposures and radiation release rates are obtained from dose projections normally performed by NERO personnel. The results of these projections are then transmitted to the Control Room Crew. The Crew must determine that the calculated results exceed the limits for General Emergency level releases (1R or 1Whour TEDE or 5R or 5Whour Thyroid CDE at the EPB) as noted on EO-000-105 Table 13.
Performance Criteria Perform a Rapid Depressurization per EO-000-112 when EPB dose or dose rates are projected to exceed EO-000-105 Table 13 values.
Initiate ADS / Manually open all 6 ADS valves.
Performance Feedback Initiating a rapid depressurization causes Reactor pressure to lower which lowers the driving force of any primary system breach.
Verify ADS valves are open using red light indication, acoustic monitoring, lowering Reactor pressure and rising Reactor water level.

SUMMARY
The plant is operating with Unit 1 at -70% power and Unit 2 at 100% power. RClC is tagged out for maintenance. The scenario begins with the crew performing the quarterly LOCA test of Drywell Area Unit Coolers and Fans IAW SO-160-001. During this test, fan 1V414A trips, resulting in a failed surveillance test and the need for the Unit Supervisor to take the required actions of Tech Specs.
After the crew responds to the failed Drywell Cooler Fan, Condensate Pump C will trip along with a simultaneous RFPT A control signal failure. The crew will respond by taking manual control of the Feedwater Level Control System.
This is followed by a leak on Containment Instrument Gas pressure transmitter PT-12643. The crew will respond to the Control Room annunciator and dispatch an operator to the field who will report the leak.
The leak causes a swap to the bottle header and requires a Technical Specifications and Technical Requirements review by the US.
After actions for the failed CIG instrument are complete, the outboard MSlVs will fail closed. This initiates a Reactor scram and the resulting RPV pressure surge causes the bottom head drain line inside the Drywell to crack. The SRVs operate to limit the pressure rise as designed; however, two SRVs (G and K) stick open, The crew will attempt to close the stuck open SRVs IAW ON-183-001, but will not be successful. However, 3-4 minutes into the event, the SRVs will close.
.-- The crew will enter EO-000-102, RPV Control, at 1087 psig, and EO-000-103, Primary Containment Control, @ 1.72 psig and 150°F. At 1.72 psig, HPCl will fail to auto start, but when manually initiated, HPCl trips and cannot be restarted. RClC is unavailable (tagged out of service for maintenance).
Drywell pressure and temperature continue to increase. Elevated Drywell temperatures will require the crew to evaluate Figure 1, RPV Saturation Temperature to verify level instrument availability.
RPV level continues to drop due to the break on the bottom head drain line. At -38, the Recirc pumps trip, resulting in a +50 level swell. SRV operation to maintain RPV pressure c 1087 will result in inventory loss (maximized CRD is the only source of high pressure injection). When RPV level is < -161 and RPV pressure is > 125 psig (EO-000-102 step RC/L-15), the crew will be required to rapidly depressurize.
Condensate will not inject due to pre-inserted failures of the Feedwater Low Load Valve (HV-10641) and Bypass (HV-10640). After water level is recovered, the crew will address containment parameters.
The scenario will be terminated when RPV level is restored to + I 3 to +54 and primary containment parameters are being addressed.

- Initiate D w e l l sprays when Suppression Chamber pressure exceeds 13 psig Safety Significance Maintenance of primary containment integrity.
Actions are taken to spray the Drywell during a LOCA when the Suppression Chamber pressure exceeds 13 psig. From the Susquehanna Emergency Operating Procedures basis document, EO-000-103, The value of 13 psig is the lowest suppression chamber pressure which can occur when 95% of the non-condensables (Nitrogen) in the drywell have been transferred to the suppression chamber. At 13 psig suppression chamber pressure, 5% of the non-condensables remain in the drywell. This 5% value is the limit established to preclude chugging - the cyclic condensation of steam at the downcomer openings of the drywell vents. Values in excess of 13 psig are indicative of more non-condensables in the drywell, meaning chugging is more probable.
Chugging (steam bubble collapse at the downcomer exit resulting in a water in-rush to fill the voided areas) induces stresses at the junction of the downcomers and the drywell floor. Repeated such stresses may result in failure of these joints, creating a direct bypass from drywell to suppression chamber.
Bypassing the suppression pool will directly pressurize the primary containment during a LOCA may result in failure.
\_.-
By requiring drywell sprays at 13 psig in the suppression chamber (5% non-condensables in the drywell),
a drywell non-condensable value of >I% will be maintained and chugging should not occur.
From Appendix D of NUREG-1021, Draft Revision 9, the critical task listed above has essential safety action that correctly completed, will prevent degradation of any barrier to fission product release and the crew will take action to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition describe in the previous paragraph.
Consequences of Failure to Perform the Task Potential failure of primary containment.

[Directions to initiate drywell sprays]
Drywell spray operation may affect the availability of electrical equipment located in the drywell.
Therefore, suppression chamber sprays are given the maximum time allowable to reduce primary containment pressure before operation of drywell sprays is required. The allowable time is determined by the suppression chamber pressure which is equated to the amount of non-condensables remaining in the drywell.

Page 8 Scenario ILO-401 Rev. 0, 2/23/2004 CRITICAL TASKS The value of 73 psig is the lowest suppression chamber pressure which can occur when 95% of the non-condensables (NJ in the drywell have been transferred to the suppression chamber. That is, at least 5% non-condensables remain in the drywell when suppression chamber pressure reaches 73 psig. This non-condensable concentration limit is established to preclude chugging - the cyclic condensation of steam at the downcomer openings of the drywell vents. A suppression chamber pressure greater than 13 psis could be indicative of a lower concentration of non-condensables in the drywell, thereby meaning that chugging is more probable.
Chugging occurs when a steam bubble collapses at the exit of the downcomers, the rush of water drawn into the downcomers to fill the void induces stresses at the junction of the downcomers and the drywell floor. Repeated occurrence of such stresses could cause fatigue failure of these joints, thereby creating a direct path between the drywell and suppression chamber. Steam discharged through the downcomers could then bypass the suppression pool and directly pressurize the primary containment. Scale model tests have demonstrated that chugging will K t occur so long as the drywell contains at least I % non-condensables. To preclude conditions under which chugging may occur, drywell sprays are conservatively required when at least 5% non-condensables remain in the drywell, Le., suppression chamber pressure reaches 13 psig.

CRITICAL TASKS
- Limit Drywell sway flow to between 1000 and 2800 nDm for the first 30 seconds Safety Significance Maintenance of primary containment integrity.
Actions are taken to limit the system flowrates when first initiating drywell sprays (1000 to 2800 gpm for the first 30 seconds). The reason for this restriction is to limit the magnitude of the drywell pressure reduction such that it will not go less than atmospheric (prevents air from being drawn in to containment) and ensures a margin to the negative design pressure of the containment.
The BWR Owners Group Emergency Operating Procedures Basis document discusses drywell spray limitations utilizing a Drywell Spray Initiation Limit Curve to protect against containment damage from exceeding the design drywell to suppression chamber differential pressure. From the Susquehanna Emergency Operating Procedures basis document, EO-000-103, A drywell spray initiation limit has been developed by PPL which provides the same protection guarantees without necessitating the use of an additional curve on the EOP flowcharts. By limiting drywell spray flow to between 1000 and 2800 gpm for the first 30 seconds of drywell spray operation, drywell sprays can be initiated without concern in all regions of the BWR Owners Group curve. After 30 seconds of operation, the drywell atmosphere contains sufficient vapor to allow full drywell sprays flow. In other words, spraying the drywell within
.%.--. these limits will not result in a drywell pressure rapid reduction such that the differential pressure limit would be challenged.
From Appendix D of NUREG-I 021, Draft Revision 9, the critical task listed above has essential safety action that correctly completed, will prevent degradation of any barrier to fission product release and the crew will take action to effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition describe in the previous paragraph.

By limiting drywell spray flow to between 1000 and 2800 gpm for the first 30 seconds of drywell spray operation, drywell sprays can be initiated without concern in all regions of this curve. After 30 seconds, the drywell atmosphere contains sufficient vapor to allow full drywell sprays flow. For this reason, the curve is not included.

- Secure D w e l l sprays before D w e l l pressure drops to 0 psig
- Secure Suppression Chamber sprays before Suppression Chamber pressure drops to 0 psig Safety Significance Operation of drywell / suppression chamber sprays is stopped before drywell / suppression chamber pressure decreases to 0 psig to assure that primary containment pressure is not reduced below atmospheric. A positive primary containment pressure precludes air from being drawn in through a primary containment path (which may have been opened for control of primary containment hydrogen and oxygen). It also assures that a margin to the negative design pressure of the primary containment exists.

As many of these systems as necessary must be used to establish and maintain the conditions required to verify RPV flooding. Establishing adequate core cooling conditions dictates that adherence to Vortex limits not be required.
Three conditions must be satisfied to verify RPV flooding without direct indication of RPV water level:
I . At least 4 SRVs must be open. This ensures that adequate steam flow will exist for cooling any unsubmerged portion of the core when RPVpressure is 2 81 psid above suppression chamber pressure.
- 2. RPV pressure must E t be decreasing. This ensures that the required steam flow wi/l be maintained.
- 3. RPV pressure must be greater than suppression chamber pressure by at least 81 psid, the Minimum RPV Flooding Pressure (MRFP).
The MRFP is defined to be the lowest differential pressure between the RPV and the suppression chamber at which steam flow through 4 SRVs is sufficient to remove decay heat. The assumed decay heat generation rate is ten minutes after shutdown from full power. Since ten minutes is the earliest that RPV flooding could reasonably be expected to be needed, establishing and maintaining RPV pressure above the MRFP assures that more than enough steam flows through the SRVs to carry away all core decay heat.
This requires that a sufficient quantity of water reach the core to carry away decay heat by boiling, which in turn requires that RPV water level increase. Maintaining this above the minimum pressure (81 psid) assures that the RPV will ultimately flood to the main steam lines.
Indications/Cues for Event Requiring Critical Task Violation of the RPV Saturation Curve is indicated by PlCSY format (RPVSAT) showing purple indication on the curve, plot on the unsafe side by the Crew and/or RPV level instrumentation failing in the upscale direction.
