I ILT NRC-ESG-001 I. OBJECTIVES Enabling Objectives A. Given the unit at power the crew will reduce power to remove a Heater Drain Pump from service, 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.

II. MAJOR EVENTS 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 75

I ILT NRC-ESG-001 III. SCENARIO

SUMMARY

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 D/G.

B. Once the crew takes the watch they will reduce reactor power to 90% at 30% per hour to remove 22 Heater Drain pump from 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 AB.SW-0003 and direct crew actions to isolate and remove #2 bay from service.

E. When the bay isolated a SGTL will occur on 21 SG. The CRS will enter AB.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 will perform actions of EOP-TRIP-1 and then transition to EOP-SGTR-1 3 of 75

I ILT NRC-ESG-001 VII. ESG CRITICAL TASK RATIONAL CT#1 (E-3 --A): Close 21AF11 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 (>10 min) prevents the crew from 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 failure/incorrect auto actuation of and ESF system or component
  • Effectively direct/manipulate ESF controls.

CT#3 (E-3 --B) Establish/maintain 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 CT# 4 (E-3 --C) Depressurize RCS until Ruptured SG and RCS pressure are equal and PZR level is > 11% with Subcooling >0, before water release from ruptured SG PORV or Safety valve Basis Failure to stop reactor coolant leakage into a ruptured SG by depressurizing the RCS needlessly complicates mitigation of the event. It also constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario 19 of 75

I ILT NRC-ESG-001 ATTACHMENT 1 SIMULATOR READY-FOR-TRAINING CHECKLIST 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...

  • degradation of any barrier to fission product release
  • a violation of a safety limit
  • a violation of the facility license condition
  • 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...
  • effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition described in the previous paragraph.
  • recognize a failure or an incorrect automatic actuation of an ESF system or component.
  • take one or more actions that would prevent a challenge to plant safety.

IAW approved station procedures.

B. Given the unit at power with a loss of tripping capability on a reactor trip breaker, the crew will validate the alarm, IAW approved station procedures.

C. Given the unit with a trip of the running charging pump, the crew will place another pump in service, IAW approved station procedures.

D. Given the unit at power with a partial loss of off-site power, the crew will take actions to stabilize the unit, IAW approved station procedures.

E. Given the unit with a LOCA in progress, the crew will take corrective actions to mitigate the accident, IAW approved station procedures.

F. Given the unit with a total loss of off-site power and a LOCA in progress, the crew will take actions to restore safeguards equipment, IAW approved station procedures.

XII. MAJOR EVENTS A. Raise power to place Turbine on Line B. Loss of Tripping Capability on RTB B C. 23 CV Pump Trip D. Loss of 3 SPT E. Small Break LOCA F. Loss of Off-Site Power 2 of 75

I ILT NRC-ESG-002 XIII. SCENARIO

SUMMARY

A. The crew will receive the unit at 4.5% power returning from a forced outage to repair Digital EHC problems. All approvals and surveillances are complete and approval to proceed to mode 1 has been given. Order to the shift is to raise power to 18% in preparation for placing turbine on line.

B. After the power ascension is in progress an electrical malfunction will cause the A Reactor Trip breaker to lose 125V DC causing the loss of Shunt trip capability. The CRS will evaluate the operability of the trip breaker and enter the tech spec action statement.

C. After the tech spec is entered the in service charging pump will trip additionally the letdown orifice isolation valve will fail partially open. The crew will isolate letdown and place a standby charging pump in service IAW AB.CV-0001. Once charging is restored excess letdown will be placed in service.

D. After excess letdown is in service 3 station power transformer will trip. This will cause a loss of 2 group busses and RCPs. No auto trip signal will occur at <P-10. The crew will enter AB.LOOP-0003, which will direct a Reactor Trip.

E. After the crew has transitioned to EOP-TRIP-2, a LOCA will occur and Auto SI initiation will fail. The crew will manually initiate SI and re-enter the EOP network.

F. After the crew has progressed to EOP-LOCA-1 and reset safeguards a loss of Off-site power will occur. The crew will reset the SECs and load the ECCS equipment required for the LOCA conditions. The scenario will end after safeguard loads are started.

I ILT NRC-ESG-002 XVII. ESG CRITICAL TASK RATIONAL 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 (from 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 beginsThe 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 1 SIMULATOR READY-FOR-TRAINING CHECKLIST 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.

II. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents...

  • degradation of any barrier to fission product release
  • a violation of a safety limit
  • a violation of the facility license condition
  • a significant reduction of safety margin beyond that irreparably introduced by the scenario B. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to...
  • effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition described in the previous paragraph.
  • recognize a failure or an incorrect automatic actuation of an ESF system or component.
  • take one or more actions that would prevent a challenge to plant safety.

XXI. MAJOR EVENTS A. Abnormal Grid B. 22 Loop Tavg fails as is C. CCW Leak D. Main Power Transformer Failure E. Loss of Heat Sink 2 of 75

I ILT NRC-ESG-003 XXII. SCENARIO

SUMMARY

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 from 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 NEO 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 XXVI. ESG CRITICAL TASK RATIONAL CT#1(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.1-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.1 --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-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.

III. Examples of CTs involving essential safety actions include those for which operation or correct performance prevents...

  • degradation of any barrier to fission product release
  • a violation of a safety limit
  • a violation of the facility license condition
  • a significant reduction of safety margin beyond that irreparably introduced by the scenario C. Examples of CTs involving essential safety actions include those for which a crew demonstrates the ability to...
  • effectively direct or manipulate engineered safety feature (ESF) controls that would prevent any condition described in the previous paragraph.
  • recognize a failure or an incorrect automatic actuation of an ESF system or component.
  • take one or more actions that would prevent a challenge to plant safety.
