I ILT NRC-ESG-001 Enabling Objectives A. Given the unit at power the crew will reduce power to remove a Heater Drain Pump from sewice, IAW approved station procedures. | |||
. | B. Given the unit at power with a failure of a Pressurizer Pressure control channel, the crew will take action to stabilize RCS pressure and swap to a non-failed channel, IAW approved station procedures. | ||
C. Given the unit with a leak in a SW bay, the crew will take action to isolate the leak, IAW approved station procedures. | |||
D. Given a SGTL, the crew will identify and isolate the leaking SG, IAW approved station procedures. | |||
E. Given the unit with a SGTR and loss of off-site power, take actions to minimize off site dose and RCS leakage, IAW approved station procedures. | |||
A. Power Reduction to 90% | |||
: | B. Pressurizer Pressure Channel 1 Fails High C. #2 SW Bay Leak D. SGTL E. SGTR on 21 SG with Loss of Off-Site Power and B Vital Bus 2 of 24 | ||
I ILT NRC-ESG-001 A. The crew will receive the unit at 100% power with all system in automatic. One major piece of equipment will be C/Ted, 2B DIG. | |||
B. Once the crew takes the watch they will reduce reactor power to 90% at 30% per hour to remove 22 Heater Drain pump fkom service due to an emergent mechanical seal leak. | |||
C. Once the power reduction to 90% is underway Channel 1 Pressurizer Pressure will fail high. | |||
The RO will take manual control of the Master Pressure Controller and adjust demand to stabilize RCS pressure. The CRS will enter AB.PZR-0001 and direct crew actions to remove the channel from service. | |||
RO | D. After AB.PZR-0001 has been completed to the point of determining channel operability a leak will begin in #2 SW Bay. The CRS will enter AELSW-0003 and direct crew actions to isolate and remove #2 bay fiom service. | ||
E. When the bay isolated a SGTL will occur on 21 SG. The CRS will enter AE3.SG-0001 and direct the crew to perform actions to address the SGTL. During the SGTL, the SG tube will rupture. The CRS will direct a manual SI initiation. | |||
F. The RO will manually initiate SI and commence the Immediate Actions of EOP-TRIP-1. The CRS will enter EOP-TRIP-1. During the performance of EOP-TRIP-1 a loss of off-site power will occur coincident with the loss of B Vital Bus. This will necessitate the crew manually isolating service water to the turbine building. | |||
G. The crew wilI perform actions of EOP-TRIP-l and then transition to EOP-SGTR-1 3 of24 | |||

I ILT NRC-ESG-001 CT#1 (E-3 --A): Close 21AFll and 21 within 10 min on identification of fault and complete isolation of Ruptured Steam Generator Basis Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and intact SGs. Upon loss of differential pressure the crew must transition to a contingency procedure that necessitates the crew taking compensating action that complicates the event mitigation strategy.. . | |||
For feedwater, isolation must occur after ruptured SG level exceeds minimum indication (9%). ..Any delay in the AFW isolation allows the ruptured SG level to increase as the AFW adds additional inventory along with the primary to secondary leakage. Too long a delay (>lo min) prevents the crew fi-om depressurizing and terminating SI before excessive inventory seriously damages the SG as a fission product barrier. | |||
CT#2 (E-0 --L): Manually start and align the minimum ESW pumps in an operating safeguard train Basis Failure to manually start and align the minimum required number of ESW pumps in an operating safeguards train represents a demonstrated inability by the crew to: | |||
Recognize a failurehcorrect auto actuation of and ESF system or component 0 Effectively direcumanipulate ESF controls. | |||
CT#3 (E-3 --B) EstablisWmaintain an RCS temperature so that a transition from SGTR-1 does not occur Basis Failure to establish and maintain correct RCS temperature during a SGTR leads to a transition from SGTR-1 to a contingency procedure, which constitutes an incorrect performance that necessitates the crew taking compensating action that complicates the event mitigation strategy.. . | |||

I ILT NRC-ESG-001 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant. | |||
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant. | |||
I. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents... | |||
e degradation of any barrier to fission product release e degraded emergency core cooling system (ECCS) or emergency power capacity e a violation of a safety limit e a violation of the facility license condition e incorrect reactivity control (such as failure to initiate Emergency Boration or Standby Liquid Control, or manually insert control rods) e a significant reduction of safety margin beyond that irreparably introduced by the scenario A. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to ... | |||
e effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition described in the previous paragraph. | |||
e recognize a failure or an incorrect automatic actuation of an ESF system or component. | |||
e take one or more actions that would prevent a challenge to plant safety. | |||

I ILT NRC-ESG-002 CT-1 (E-0 -D): Manually actuate at least 1 train of Safety Injection before transition to any LOCA, or FR procedure or completion of step 9 of Trip-2. | |||
BASIS: Failure to manually actuate SI under postulated conditions constitutes mis-operation or incorrect crew performance that leads to degraded ECCS capacity Additionally, failure to manually actuate SI (when it is possible to do so) results in a significant reduction in safety margin beyond that irreparably introduced by the scenario. Finally, failure to manually actuate SI is a violation of the facility license condition CT #2 (E-1-C): Trip all RCPs prior to RCS inventory becoming depleted to critical inventory. (within 5 mins of RCS pressure < 1350 with ECCS flow) | |||
BASIS: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200. Thus, failure to perform the task represents mis-operation or incorrect crew performance which leads to the degradation of a barrier to fission product release. | |||
WOG sponsored analysis to demonstrate that the operating crew would have sufficient time (fiom the point at which the criteria was met) to recognize the indications that the criteria are met and trip RCPs before the window for adverse consequence begins.. .The minimum response time for the operating crew is 5 minutes.. . if the RCPs are tripped within 5 minutes of the trip criteria being met, PCT remains below 2200 CT#3: Re-establish plant design basis conditions by starting at least one train of ECCS equipment after a loss of off-site power occurs with SI Reset. | |||
BASIS: FSAR assumption of minimum ECCS flow per section 15.3.1.2. | |||

I ILT NRC-ESG-002 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant. | |||
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant. | |||
I. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents... | |||
e degradation of any barrier to fission product release e degraded emergency core cooling system (ECCS) or emergency power capacity e a violation of a safety limit e a violation of the facility license condition e incorrect reactivity control (such as failure to initiate Emergency Boration or Standby Liquid Control, or manually insert control rods) e a significant reduction of safety margin beyond that irreparably introduced by the scenario A. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to ... | |||

I ILT NRC-ESG-003 CT#l(E-0 -P) Manually initiate MSLI before a severe challenge develops to either subcriticality or Integrity CSF or transition to LOSC BASIS: Failure to close the MSIVs under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Additionally, such an omission constitutes a demonstrated inability by the crew to recognize a failure of the auto actuation of an ESF system or component and to take action that would prevent a challenge to plant safety. | |||
CT#2A (FR-H.l-A)Establish feedwater flow into at least one Steam Generator before RCS Bleed and Feed is required. | |||
BASIS: Failure to establish feedwater flow to any SG results in the crews having to rely upon the lower priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that leads to degradation of any barrier to fission product release. | |||
NOTE: This Critical Task will be considered NOT satisfied if in the opinion of the Evaluators the bleed and feed criteria is reached due to mis-operation, inaction or delay by the crew. If the bleed and feed criteria is reached as a direct result of the failure of the automatic MSLI then the action of the crew will be based on CT-2B. Thus, when the crew fails to simply establish available feedwater flow (as it could, given postulated conditions) before SG dryout occurs, it necessitates the crew taking compensating action which complicates the event mitigation strategy. | |||

This constitutes a | BASIS: Failure to establish RCS bleed and feed before automatic opening of the PORVs reduces the probability of success to establish a heat sink for the core. This constitutes a significant reduction of the safety margin beyond that irreparably introduced by the scenario NOTE: The PORV opening as stated in the critical task means opening caused by the RCS heatup from loss of heat sink. If the PORV opens for any other cause, it does not constitute a misoperation of the critical task. | ||

I ILT NRC-ESG-003 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant. | |||
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant. | |||
I. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents.. | |||
e degradation of any barrier to fission product release e degraded emergency core cooling system (ECCS) or emergency power capacity a violation of a safety limit e a violation of the facility license condition e incorrect reactivity control (such as failure to initiate Emergency Boration or Standby Liquid Control, or manually insert control rods) e a significant reduction of safety margin beyond that irreparably introduced by the scenario A. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to ... | |||
e effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition described in the previous paragraph. | |||
a recognize a failure or an incorrect automatic actuation of an ESF system or component. | |||

I ILT NRC-ESG-004 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant. | |||
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant. | |||
I. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents... | |||
e degradation of any barrier to fission product release e degraded emergency core cooling system (ECCS) or emergency power capacity e a violation of a safety limit e a violation of the facility license condition e incorrect reactivity control (such as failure to initiate Emergency Boration or Standby Liquid Control, or manually insert control rods) e a significant reduction of safety margin beyond that irreparably introduced by the scenario A. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to ... | |||

B. Given the unit at power with a failure of a Pressurizer Pressure control channel, the crew will take action to stabilize RCS pressure and swap to a non-failed channel, IAW approved station procedures.
C. Given the unit with a leak in a SW bay, the crew will take action to isolate the leak, IAW approved station procedures.
D. Given a SGTL, the crew will identify and isolate the leaking SG, IAW approved station procedures.
E. Given the unit with a SGTR and loss of off-site power, take actions to minimize off site dose and RCS leakage, IAW approved station procedures.
A. Power Reduction to 90%
B. Pressurizer Pressure Channel 1 Fails High C. #2 SW Bay Leak D. SGTL E. SGTR on 21 SG with Loss of Off-Site Power and B Vital Bus 2 of 24
I ILT NRC-ESG-001 A. The crew will receive the unit at 100% power with all system in automatic. One major piece of equipment will be C/Ted, 2B DIG.
B. Once the crew takes the watch they will reduce reactor power to 90% at 30% per hour to remove 22 Heater Drain pump fkom service due to an emergent mechanical seal leak.
C. Once the power reduction to 90% is underway Channel 1 Pressurizer Pressure will fail high.
The RO will take manual control of the Master Pressure Controller and adjust demand to stabilize RCS pressure. The CRS will enter AB.PZR-0001 and direct crew actions to remove the channel from service.
D. After AB.PZR-0001 has been completed to the point of determining channel operability a leak will begin in #2 SW Bay. The CRS will enter AELSW-0003 and direct crew actions to isolate and remove #2 bay fiom service.
E. When the bay isolated a SGTL will occur on 21 SG. The CRS will enter AE3.SG-0001 and direct the crew to perform actions to address the SGTL. During the SGTL, the SG tube will rupture. The CRS will direct a manual SI initiation.
F. The RO will manually initiate SI and commence the Immediate Actions of EOP-TRIP-1. The CRS will enter EOP-TRIP-1. During the performance of EOP-TRIP-1 a loss of off-site power will occur coincident with the loss of B Vital Bus. This will necessitate the crew manually isolating service water to the turbine building.
G. The crew wilI perform actions of EOP-TRIP-l and then transition to EOP-SGTR-1 3 of24

I ILT NRC-ESG-001 CT#1 (E-3 --A): Close 21AFll and 21 within 10 min on identification of fault and complete isolation of Ruptured Steam Generator Basis Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and intact SGs. Upon loss of differential pressure the crew must transition to a contingency procedure that necessitates the crew taking compensating action that complicates the event mitigation strategy.. .
For feedwater, isolation must occur after ruptured SG level exceeds minimum indication (9%). ..Any delay in the AFW isolation allows the ruptured SG level to increase as the AFW adds additional inventory along with the primary to secondary leakage. Too long a delay (>lo min) prevents the crew fi-om depressurizing and terminating SI before excessive inventory seriously damages the SG as a fission product barrier.
CT#2 (E-0 --L): Manually start and align the minimum ESW pumps in an operating safeguard train Basis Failure to manually start and align the minimum required number of ESW pumps in an operating safeguards train represents a demonstrated inability by the crew to:

CT#3 (E-3 --B) EstablisWmaintain an RCS temperature so that a transition from SGTR-1 does not occur Basis Failure to establish and maintain correct RCS temperature during a SGTR leads to a transition from SGTR-1 to a contingency procedure, which constitutes an incorrect performance that necessitates the crew taking compensating action that complicates the event mitigation strategy.. .

- 1. THE SCENARIO HAS CLEARLY STATED OBJECTIVES IN THE SCENARIO.
- 2. The initial conditions are realistic, equipment and/or instrumentation may be out of service, but it does not cue the crew into expected events.
- 3. Each event description consists of:
0 The point in the scenario when it is to be initiated, 0 The malfunction(s) that are entered to initiate the event, 0 The symptoms/cues that will be visible to the crew, The expected operator actions (by shift position), and The event termination point.
- 4. The use of non-mechanistic failures (e.g. pipe break) should be limited to one or a credible preceding event has occurred.
- 5. The events are valid with regard to physics and thermodynamics.
- 6. Sequencingtiming of events is reasonable (e.g. the crew has time to respond to the malfunctions in an appropriate time fiame and implements procedures and/or corrective actions).
- 7. Sequencinghiming of events is reasonable, and allows for the examination team to obtain complete evaluation results commensurate with the scenario objectives.
- 8. If time compression techniques are used, scenario summary clearly so indicates.
- 9. The simulator modeling is not altered.
-10. All crew competencies can be evaluated.
- 11. Appropriate reference materials are available (SOERs, LERs, etc.).

I ILT NRC-ESG-001 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant.
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant.
I. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents...
e degradation of any barrier to fission product release e degraded emergency core cooling system (ECCS) or emergency power capacity e a violation of a safety limit e a violation of the facility license condition e incorrect reactivity control (such as failure to initiate Emergency Boration or Standby Liquid Control, or manually insert control rods) e a significant reduction of safety margin beyond that irreparably introduced by the scenario A. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to ...
e effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition described in the previous paragraph.
e recognize a failure or an incorrect automatic actuation of an ESF system or component.
e take one or more actions that would prevent a challenge to plant safety.
e prevent inappropriate actions that create a challenge to plant safety (such as an unintentional Reactor Protection System (RPS) or ESF actuation.

I ILT NRC-ESG-002 CT-1 (E-0 -D): Manually actuate at least 1 train of Safety Injection before transition to any LOCA, or FR procedure or completion of step 9 of Trip-2.
BASIS: Failure to manually actuate SI under postulated conditions constitutes mis-operation or incorrect crew performance that leads to degraded ECCS capacity Additionally, failure to manually actuate SI (when it is possible to do so) results in a significant reduction in safety margin beyond that irreparably introduced by the scenario. Finally, failure to manually actuate SI is a violation of the facility license condition CT #2 (E-1-C): Trip all RCPs prior to RCS inventory becoming depleted to critical inventory. (within 5 mins of RCS pressure < 1350 with ECCS flow)
BASIS: Failure to trip the RCPs under the postulated plant conditions leads to core uncovery and to fuel cladding temperatures in excess of 2200. Thus, failure to perform the task represents mis-operation or incorrect crew performance which leads to the degradation of a barrier to fission product release.
WOG sponsored analysis to demonstrate that the operating crew would have sufficient time (fiom the point at which the criteria was met) to recognize the indications that the criteria are met and trip RCPs before the window for adverse consequence begins.. .The minimum response time for the operating crew is 5 minutes.. . if the RCPs are tripped within 5 minutes of the trip criteria being met, PCT remains below 2200 CT#3: Re-establish plant design basis conditions by starting at least one train of ECCS equipment after a loss of off-site power occurs with SI Reset.
BASIS: FSAR assumption of minimum ECCS flow per section 15.3.1.2.

I ILT NRC-ESG-002 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant.
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant.

I ILT NRC-ESG-003 A. The crew takes the watch at 100% power. 21 AFW Pump is tagged for bearing replacement.
B. Once the crew assumes the watch the DC neutral ground current will rise to 25 amps. The crew will enter AB.GRID-0001 and reduce power to 942 MWe. During the power reduction 22 Loop Tavg will fail as is resulting in excessive rod motion. The crew will enter AB.ROD-0003 and remove the channel fi-om service.
C. After the channel is removed from service, a leak develops in the CCW system. The crew should implement AB.CC-0001 to establish makeup flow and isolate the leak.
D. Following isolation of the CCW leak, an OHA alarm comes in on MPT Phase 1. The N E 0 will report a major oil leak on the MPT and a desire to leave the area because of electrical arcing noises.
The CRS should order a manual reactor trip.
E. The Turbine fails to trip on the reactor trip and MSLI fails to auto initiate. The crew should initiate a MSLI as part of immediate actions of EOP-TRIP-1. Safety Injection will occur based on the high steam flow.
F. 23 AFWP trips when it auto starts and is not able to be reset. After AFW flow is throttled to 22e4, 22 AFWP breaker trips open. The crew should transition to FRHS-1 when the RED PATH conditions are met. In FRHS-1, the crew should stop the RCPs; select 1 SG for depressurization to allow feed using a Condensate pump.
G. The Lead Evaluator can terminate the scenario any time after S/G WR level is observed rising.
H. NOTE: Depending on timing of the MSLI and progress through the procedures, RCS Bleed and Feed criteria may be met before the Condensate pump is feeding the S/G. In that case, the crew will initiate RCS Bleed and Feed then feed the S/Gs via a Condensate Pump.

I ILT NRC-ESG-003 CT#l(E-0 -P) Manually initiate MSLI before a severe challenge develops to either subcriticality or Integrity CSF or transition to LOSC BASIS: Failure to close the MSIVs under the postulated plant conditions causes challenges to CSFs beyond those irreparably introduced by the postulated conditions. Additionally, such an omission constitutes a demonstrated inability by the crew to recognize a failure of the auto actuation of an ESF system or component and to take action that would prevent a challenge to plant safety.
CT#2A (FR-H.l-A)Establish feedwater flow into at least one Steam Generator before RCS Bleed and Feed is required.
BASIS: Failure to establish feedwater flow to any SG results in the crews having to rely upon the lower priority action of establishing RCS bleed and feed to minimize core uncovery. This constitutes incorrect performance that leads to degradation of any barrier to fission product release.
NOTE: This Critical Task will be considered NOT satisfied if in the opinion of the Evaluators the bleed and feed criteria is reached due to mis-operation, inaction or delay by the crew. If the bleed and feed criteria is reached as a direct result of the failure of the automatic MSLI then the action of the crew will be based on CT-2B. Thus, when the crew fails to simply establish available feedwater flow (as it could, given postulated conditions) before SG dryout occurs, it necessitates the crew taking compensating action which complicates the event mitigation strategy.
CT#2B (FR-H.l --B) Establish RCS Bleed and Feed before PZR PORVs open due to loss of heat sink.
BASIS: Failure to establish RCS bleed and feed before automatic opening of the PORVs reduces the probability of success to establish a heat sink for the core. This constitutes a significant reduction of the safety margin beyond that irreparably introduced by the scenario NOTE: The PORV opening as stated in the critical task means opening caused by the RCS heatup from loss of heat sink. If the PORV opens for any other cause, it does not constitute a misoperation of the critical task.

I ILT NRC-ESG-003 ATTACHMENT 2 CRITICAL TASK METHODOLOGY In reviewing each proposed CT, the examination team assesses the task to ensure, that it is essential to safety. A task is essential to safety if, in the judgment of the examination team, the improper performance or omission of this task by a licensee will result in direct adverse consequences or in significant degradation in the mitigative capability of the plant.
The examination team determines if an automatically actuated plant system would have been required to mitigate the consequences of an individuals incorrect performance. If incorrect performance of a task by an individual necessitates the crew taking compensatory action that would complicate the event mitigation strategy, the task is safety significant.
I. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents..
e degradation of any barrier to fission product release e degraded emergency core cooling system (ECCS) or emergency power capacity a violation of a safety limit e a violation of the facility license condition e incorrect reactivity control (such as failure to initiate Emergency Boration or Standby Liquid Control, or manually insert control rods) e a significant reduction of safety margin beyond that irreparably introduced by the scenario A. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to ...

I ILT NRC-ESG-004 A. Given the unit at power and a failure of a Power Range Nuclear Instruments, the crew will take corrective actions to stabilize the plant, IAW approved station procedures.
B. Given a situation with an OHA alarm, perform action(s) to investigate and correct the cause of the alarm, IAW approved station procedures.
C. Given the unit at power with a failed closed stop or governor valve, the crew will reduce load to <75% at 5%/min, AW approved station procedures.
D. Given RCPs with a malfunction, the crew will take action to remove the RCPs from service, IAW approved station procedures.
E. Given the unit with a loss of all vital busses, the crew will perform actions to attempt to recover vital busses and maintain RCP seal integrity, IAW approved station procedures.
A. PR NIS Fails High B. 23 SW Pump Strainer Clogs C. Main Turbine Governor Valve Fails Closed D. Inadvertent Phase B E. LOPA 2 of 24
I ILT NRC-ESG-004 A. The crew will receive the unit at 100% power with all systems in automatic. 2B D/G will be C/Ted. 2PR1 will be isolated due to a leak.
B. Once the crew assumes the watch, 2N44 will fail high. The RO will place rods in manual and the CRS will enter AB.NIS-0001 to remove the channel fiom service.
C. Before the channel is removed fiom service a high DP will occur on 23 SW strainer, header pressure will lower and the stand-by pump will fail to auto start. The crew will refer to the alarm response procedure stop the pump and start a stand-by pump.
D. Once the service water issue is addressed, a main turbine governor valve will fail closed. The crew will reduce power at S%/min to 75% power. When boration is started for the power reduction the auto boron setpoint will fail to 5 gpm, the RO will initiate a manual boration E. During the power reduction, an inadvertent Phase B will occur and the crew will trip the reactor and stop all RCPs IAW AB.RCP-0001.
F. During the reactor trip response all vital busses will be deenergized. The crew will transition to EOP-LOPA-1 and perform a rapid RCS cooldown. Once the cooldown is established the only source of AFW will trip and all feedflow capability will be lost. The crew will stop the cooldown on all but one SG.
G. Once the steaming strategy is established, the crew will be informed 2B D/G has been released and then they will start and load 2B Bus.
H. The scenario will terminate once the vital bus is energized or at the lead evaluators discretion.

I ILT NRC-ESG-004 CT# 1: Manually trip the reactor from the control room within 5 minutes of OHA C- 16 BASIS: Conditions requiring immediate attention for operation of the RCPs. These recommendations are incorporated from Westinghouse Tech Bulletin ESBU-TB-93-01-R1 CT# 2: (LOPA-1 CAS) Stop any EDG running w/o SW BASIS: Running the EDG without ESW cooling leads to a high temperature condition that can result in EDG failure due to damage caused by engine overheating. F O G ERG Based Critical tasks)
IF a Diesel is started and can not be promptly supplied with SW cooling, it is tripped to prevent damage until SW cooling is available (LOPA-1 Basis Document)
CT# 3: (ECA-0.0-H ) Isolate RCP seal injection before a Charging Pp starts or is started BASIS: Failure to isolate RCP seal injection before starting a charging pump, under the postulated plant conditions, can result in unnecessary and avoidable degradation of the RCS fission-product barrier. (WOG ERG Based Critical tasks)
CT# 4: (ECA-0.0-G ) Depressurize intact SGs at max rate such that of the following limiting conditions are met:
0 SG depressurization is initiated until narrow range level in at least one intact SG is
>9%
0 If narrow range level cannot be maintained >9% in at least one intact SG, then depressurization is stopped until narrow range is restored to >9% in at least one intact SG a SG pressure does not lower to 4 3 5 psig a RCS cold leg temperature does not lower to <3 10°F 0 If positive SUR is indicated on either the source range or intermediate range, then the depressurization is stopped and the RCS is allowed to heat up BASIS: Failure to depressurize the secondary and cool down the RCS, under the postulated plant conditions, results in a greater possibility for core damage. The intact SGs should be depressurized as quickly as possible to minimize RCS inventory loss, but within the constraint of controllability.. .. The PORVs on all intact SGs should be wide open, provided that none of the limiting conditions associated with this critical task are violated. (WOG ERG Based Critical tasks) 18 of24
