SUMMARY
Length: 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> Initial Power Level: 1OO%, above the 100% Rod Line The scenario begins at 100% reactor power. The crew will add water to the Suppression Pool using the High Pressure Core Spray System (CSH) per normal operating procedure N2-OP-33, High Pressure Core Spray. While water is being added to the Suppression Pool, Recirc Flow Unit input to APRM/RBM fails downscale resulting in APRM high power scram signals inputted into the Power Range Monitoring System logic modules. The crew will bypass the affected instrument per normal operating procedure and annunciator response procedures.
The crew experiences a Reactor Feedwater pump trip and partial automatic Recirc Flow Control Valve (FCV) Runback. The partial runback occurs due to a trip RCS FCV hydraulic power units. The result is slowly lowering reactor water level due to failure of reactor power to be automatically reduced to within the capacity of the single remaining operating Feedwater pump.
Reactor water level will slowly approach the automatic scram low water level of 159 inches.
The crew will manually insert CRAM rods to reduce power approximately 10% to within the capacity of the single remaining operating Feedwater pump (65%). This action will return reactor water level to the normal band of 178 to 187 inches.
After the plant is stable, the total Steam flow signal to Feedwater Level Control operates erratically resulting in water level transient. The crew will take manual contol of Feedwater to stabilize level. Manual level control will be required for the remainder of the scenario.
An inadvertent opening of an ADS/SRV valve occurs. The crew will take actions required by procedures to close the valve before a manual scram is required at Suppression Pool water temperature of 1 10°F.
NRC Scenario 1 March 2005
When the ADS/SRV is closed, Main Turbine vibration begins to rise. The crew will manually scram the reactor and trip the Main Turbine when procedure limits of 12 mils are exceeded, since there are no automatic turbine trips associated with turbine vibration. When the reactor is scrammed all control rods will fail to fully insert resulting in reactor power level of approximately 20%. Heat will be added to the containment while operating SRVs for pressure control. The transient is complicated by loss of the remaining operating Feedwater pump and the inability to maintain water level above MSCRWL (-39 inches). The crew will perform an RPV Blowdown to lower RPV pressure which allows the use of RHS via Shutdown Cooling line. This is the last remaining preferred injection system. If, in the SROs judgment, additional injection sources are required to restore and maintain RPV water level above MSCRWL, Alternate Injection systems can now be lined up to restore and maintain level above -39 inches. The crew will execute Alternate Control Rod Insertion procedures to fully insert the stuck control rods, such that the reactor will remain shutdown.
Major Procedures Exercised: EOP-RPV, PC, C5,C2. SOP-6, 29,10lD, 21 and 9.
EOP-6 Attachment 14 EAL Classification: SAE 2.2.2 Any RPS scram setpoint has been exceeded AND automatic and manual scrams fail to result in a control rod pattern which assures reactor shutdown conditions without boron AND EITHER Power >4% OR Suppression Pool temperature >llO°F Termination Criteria: RPV Blowdown is complete and RPV level is restored and maintained in normal level band 160 to 200 inches and all control rods are fully inserted.

ATTACHMENT 1 (Cont) 2.2.2 Site Area Emerqency A~J RPS scram setpoint has been exceeded AND Automatic and manual scrams fail to result in a control rod pattern which assures reactor shutdown under all conditions without boron.
AND Either:
Reactor power >6%
OR Torus temperature >llO°F NUMARC IC:
Failure of Reactor Protection system instrumentation to complete or initiate an automatic reactor trip once a Reactor Protection system setpoint has been exceeded and manual scram trip was not successful.
FPB LosdPotential Loss:
NIA Mode Applicability:
Power Operation Basis:
This condition indicates failure of the Reactor Protection System to shut down the reactor (automatically or manually) and maintain it shutdown under ail conditions without boron. Under these conditions, the reactor is producing more heat than can be removed using available safety systems. A Site Area Emergency is indicated because conditions exist leading to imminent or potential loss of both the fuel clad and the primary containment.
The failure of automatic initiation of a reactor scram followed by an unsuccessful manual initiating actions which can be rapidly taken at the reactor control console does not, by itself, lead to imminent loss of either fuel clad or primary containment barriers, It is the continued criticaiity under conditions requiring a rector scram along with the continued addition of heat to the containment which poses the imminent threat to primary containment or fuel clad barriers. In accordance with the EOPs, Liquid Poison System is initiated based on heat addition to containment in excess of safety system capability under failure to scram conditions.
Page 33 EPMP-EPP-0101 Rev 07
AllACHMENT 1 (Cont)
An immediate manual scram is any set of actions by the reactor operator at the reactor control console which causes control rods to be rapidly inserted into the core and brings the reactor subcritical, including manual scram pushbuttons, ARI and mode switch.

SUMMARY
Length: 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> Initial Power Level: loo%, above the 100°/~Rod Line The scenario begins at 100% reactor power. The crew will swap Control Rod Drive Pumps to return RDS-PI B to service and remove RDS-P1A from service. After the normal evolution is complete, an outer seal leak develops on Recirc Pump (RCS) A. N2-SOP-29.1 is entered RCS pumps is removed from service and isolated. The crew will also enter N2-SOP-29 due to reduced core flow and insert Cram Rods to lower rod line below 100%. The crew will stabilize the plant in single loop and the SRO will implement the required single loop Tech Spec actions.
With the plant now stable, Control Rod Drive suction filter clogging results in the trip of the operating RDS pump and several accumulator trouble alarms. The crew will enter N2-SOP-30, trip Reactor Water Cleanup due to loss of pump seal cooling, swap RDS pump suction filters and restart an RDS pump.
A loss of one offsite 115 KV power Line 5 will occur. The Division I and Division Ill EDGs will fail to start. Manual operator action will be required to start the Division I EDG and preclude a manual scram. The Division Ill High Pressure Core Spray EDG cannot be started. The crew will implement the actions required by N2-SOP-3 to restore Service Water System flow to the Turbine and Reactor Building non safety related headers which have isolated due to the off site power loss.
A small reactor coolant leak develops inside the Drywell. This results in rising drywell temperatures and pressure. The crew will take manual action and scram the reactor. N2-EOP-RPV, PC are entered. The event is complicated by degraded ECCS response and loss of NRC Scenario 2 March 2005
electrical power. An RPV Blowdown is required to establish injection with the only remaining Low Pressure ECCS systems RHR B and C. Suppression Chamber Spray and Drywell Spray should be established to control primary containment pressure and temperature, as the LOCA becomes more severe. Drywell and Suppression Chamber Sprays will be complicated by loss of electrical power and degraded ECCS systems. The only remaining system that can be used for sprays, will also be required for RPV injection.

What we did? Why? (Goals) Other Options? I NRC Scenario 2 March 2005
Ill. PERFORMANCE OBJECTIVES
-- A. Critical Tasks:
CT-1 .O Given the plant at power with RPV pressure >900 psig and two inoperable scram accumulators, the crew will restore charging water pressure >940 psig within 20 minutes of meeting conditions for entering TS 3.1.5 Condition B, by restarting an RDS pump and avoiding the requirement to immediately scram the reactor per N2-SOP-30 and Tech Spec 3.1.5.
CT Justification: Failure to restore Charging Header Pressure by restarting RDS pump results in direct adverse consequences and a challenge to plant safety by requiring a manual scram transient to be initiated. Per Tech Spec Basis 3.1.5 With two or more control rod scram accumulators inoperable and reactor steam dome pressure >900 psig, adequate pressure must be supplied to the charging water header. With inadequate charging water pressure, all of the accumulators could become inoperable, resulting in a potentially severe degradation of the scram performance.
Therefore, within 20 minutes from discovery of charging water header pressure < 940 psig concurrent with Condition B, adequate charging water header pressure must be restored. The allowed Completion Time of 20 minutes is considered a reasonable time to place a CRD pump into service to restore the charging header pressure, if required. This Completion Time also recognizes the ability of the reactor pressure alone to fully insert all control rods.
CT-2.0 Given degraded RPV injection sources, the crew will establish RPV injection using available Preferred Injection Systems listed in Table E l of EOP-RPV to RESTORE AND MAINTAIN RPV water level above MSCRWL (-39 inches Fig 2)to preclude executing EOP-C3 or Flooding the Drywell by entering SAPS, per N2-EOP-RPV.
NRC Scenario 2 March 2005
CT Justification: Failure to restore and maintain RPV water level above -39 inches by implementing actions per EOP-RPV will result in adverse consequences to the plant by abandoning the EOP injection strategy and implementing Drywell Flooding (from EOP-RPV Step L-16) used in the SAPs. It is expected that proper implementation of EOP-RRV will result in performing an RPV Blowdown by opening 7 ADS valves to reduce RPV pressure and manual injecting RHS Pump B and RHS Pump C (either both or any one pump) which are capable of recovering level above -39 inches and ultimately above -14 inches (TAF). Water level is expected to drop below -39 inches for several minutes while executing the steps to blowdown and establish injection. There is no specific time constraints attached to this CT. As long as the crew recovers level without entering EOP-C3, Steam Cooling or the SAPs, this would demonstrate satisfactory completion of the CT.
B. Performance Objectives:
PO-I .o Given the plant with direction to swap Control Rod Drive pumps, the crew will start RDS-PI B and secure RDS-PIA per N2-OP-30 PO-2.0 Given the plant with an RCS pump seal leak, the crew will remove the pump from service per N2-SOP-29.1 and N2-SOP-29, then continue to operate the plant in single loop per with N2-0P-29.
PO-3.0 Given the plant operating at power and a Control Rod Drive pump trip with accumulator trouble alarms, the crew will restart an RDS pump within 20 minutes per N2-SOP-30 PO-4.0 Given the reactor plant operating at power when a loss of offsite line 5 with EDG failures occurs, the crew will take action to start the NRC Scenario 2 March 2005
failed EDG and stabilize service water in accordance with N2-SOP-
- 03. (Operator actions with PRA significance)
PO-5.0 Given a reactor plant operating at power with a LOCA in progress, the crew will manually scram the reactor plant prior to reaching 1.68 psig in the Containment.
PO-6.0 Given a loss of all high pressure injection the crew will restore and .
maintain RPV water level above TAF after performing an RPV Blowdown per N2-EOP-RPV and N2-EOP-C2. (Operator actions with PRA significance)
PO-7.0 Given a failure of Low Pressure ECCS pumps to start on high drywell pressure signal, the crew will manually start the Low Pressure ECCS pumps per EOP Bases and Operations Manual PO-8.0 Given the plant with a LOCA and conditions met for containment spray, the crew will initiate Containment Spray per N2-EOP-PC and EOP-6 Attachment 22.

SUMMARY
Length: 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> Initial Power Level: 4.5% with Mode Switch in STARTUP The scenario begins at about 4.5% reactor power, during plant startup. The crew will continue the startup by withdrawing control rods to raise power above 5% with subsequent Mode Switch transfer to RUN. IRM A failure due to an inop trip occurs resulting in a trip if RPS trip system A. The crew will bypass the failed instrument and reset the resulting RPS channel trip.
Feedwater Pump A minimum flow valve fails open with a concurrent failure of RPV Narrow Range level input to Feedwater Level Control System (FWLC). With the level transmitter failed as-is, an RPV water level transient results requiring crew to take manual control of level control valve to prevent an automatic protective trip function per N2-SOP-6. When level is stabilized the crew will then transfer to redundant Narrow Range transmitter per normal operating procedures and subsequently return FWLC to automatic control.
The startup now continues by withdrawing control rods to raise power to above 5% and the Mode Switch is transferred to RUN. The scenario can continue regardless of whether the crew actually places the Mode Switch to RUN. Control Rod 34-27 will drift out. N2-SOP-8 will be executed to fully insert and isolate the control rod. With power level below RWM setpoint the RWM must be bypassed to insert the drifting rod. Service Water Pump A trips occurs requiring a standby pump to be placed in service.
The major transient begins when a RClC Steam Leak into Reactor Building occurs. Automatic and manual attempts to isolate the RClC steam line will be unsuccessful. Entry in EOP-SC is required and the reactor will be manually scrammed. Reactor Building Ventilation System fails to isolate on high radiation level. This requires action to close Secondary Containment Isolation Dampers and
\
manually start Standby Gas Treatment systems to terminate a potential ground level release pathway. When Reactor Building temperatures exceed 212°F an RPV Blowdown is required. EHC NRC Scenario 3 March 2005
Pump A trips to disable the Bypass Valves as a means of rapidly reducing RPV pressure to mitigate the steam leak. ADS/SRV PSV 126 fails to open during RPV Blowdown due to Loss of N2 supply, requiring operator action to open an additional SRV to obtain the number directed by EOP-c2.

CT-1 .O Given an unplanned power change that is or is likely to cause reactor power as indicated on APRMs to rise, the crew will make an initial reactor power reduction to approximately 85% as indicated on APRMs per SOP-8 and in accordance with SOP-I 01D.
CT-2.0 Given RPV level indication is no longer valid, the crew will execute EOP-C4 to open SRVs with a minimum of 6 and a maximum of 7 ultimately opened.
CT-3.0 Given RPV Flooding in progress with RPV level below the main steam lines, the crew will establish injection to the RPV to restore and maintain RPV level at or above the main steam lines.
CT-4.0 Given the situation, RPV flooded to the main steam lines and RHR Loop A not needed to run in the LPCl mode to maintain level, divert RHR A to spray the Suppression Chamber and the Drywell.
B. Performance Objectives:
PO-I .o Given the plant experiencing an inadvertent initiation of HPCS the crew will act to place the HPCS in a safe configuration.
PO-2.0 Given the plant operating at rated power and a loss of a high pressure heater, the crew will lower power and monitor feedwater temperature and verify limits per N2-SOP-8.
PO-3.0 Given a reactor plant performing a power reduction from rated with a feedwater control malfunction, the operating crew will take NRC Scenario 4 March 2005

Directions to Operators:
Read Before Every JPM Performance:
For the performance of this JPM, I will function as the SSS, CSO, and Auxiliary Operators. Prior to providing direction to perform this task, I will provide you with the initial conditions and answer any questions. During task performance, I will identify the steps to be simulated, or discuss and provide cues as necessary.
Read Before Each Evaluated JPM Performance:
This evaluated JPM is a measure of your ability to perform this task independently. The Control Room Supervisor has determined that a verifier is not available and that additional / concurrent verification will not be provided; therefore it should not be requested.
Read Before Each Traininq JPM Performance:
During this Training JPM, applicable methods of verification are expected to be used.
Therefore, either another individual or I will act as the additional / concurrent verifier.
Notes to Instructor / Evaluator:
- 1. Critical steps are identified as PasslFail. All steps are sequenced critical unless denoted by a e.
- 2. During Evaluated JPM:
Self-verification shall be demonstrated.
- 3. During Training JPM:

ATTACHMENT 1 (Cont) 2.1.2 Site Area Emerqencv RPV water level cannot be restored and maintained > -84 in.(TAF)
OR RPV Flooding is required NUMARC IC:
Loss of reactor vessel water level has or will uncover fuel in the reactor vessel.
FPB LosdPotential Loss:
Fuel Clad Potential Loss, RCS Loss Mode Applicability:
Power Operation, Hot Shutdown, Cold Shutdown, Refuel Basis:
The RPV water level used in this EAL is the top of active fuel (TAF). This value corresponds to the level which is used to indicate challenge to core cooling and loss of the fuel ciad barrier.
Uncovery of the fuel irrespective of the event that causes fuel uncovery is justification alone for declaring a Site Area Emergency. This includes events that could lead to fuel uncsvety in any plant operating mode including cold shutdown and refuel. Escalation to a General Emergency occurs through radiological effluence addressed in EAL 1.3.3for drywell radiation and in the EALs defined for Category 5.0, Radioactivity Release.
The terminology of "cannot be restored and maintained" that is used is intended to be consisfent with the EOP terminology using the same wording. Momentary drops below the level limit would not require classification at this level.
This determination includes making an evaluation that considers both current and future system performance in relation to the current value and trend of the parameter(s). Neither implies that the parameter must actually exceed the limit before the classification is made nor that the classification must be made before the limit is reached.
This definition would require the emergency classification be made prior to water level dropping below TAF if, based on an evaluation of the current trend of RPV water level and in consideration of current and future injection system performance, that RPV water level will not likely be maintained above TAF Page 29 EPMP-EPP-0101 Rev 07
ATTACHMENT 1 (Cont)
The EOPs require RPV Flooding under conditions where RPV water level cannot be determined. The operator is directed to establish RPV Flooding conditions to assure adequate core cooling while attempting to restore RPV water level indication. Because actual RPV water level is not known under these conditions, it must be assumed that RPV water level is below the TAF thus warranting declaration of a Site Area Emergency.
