CWIP 2B needs to be removed from service to support motor oil replacement.

Event 1 Reduce reactor power to 90% to support CWIP shift lAW 20P-29 (third Condensate Pump is not available, power reduction required).

Event 2 Shift CWIPs lAW 20P-29, Section 8.14 Event 3 HPCI CST level transmitter will fail low causing auto swap of HPCI suction to the Suppression Pool. Event 3a E41-F004 (HPCI CST Suction Valve) will fail to automatically close when both the Suppression Pool Suction valves reach full open position.

Event 4 Heater Drain Pump 2A shaft seizes and trips on overcurrent.

Heater Drain tank level will rise and the crew will throttle HD-V57 to stabilize HD Tank level. If the standby HOP is not started, RFP suction pressure will lower during the transient requiring power reduction to stabilize Condensate/feedwater.

Event 5 A line rupture will develop in the RWCU system in the 77' elevation.

Event 6 MCC 2XC will de-energize due to fault from steam leaking into the Reactor Building (loss of power to G31-F001)

Event 7 G31-F004 will thermally trip. OAOP-05 will be entered and the Reactor Building temperatures and water levels will rise requiring a manual scram. Event 8 Manual Scram prior to reaching the Maximum Safe Operating Temperature or Level. Event 9 When the turbine is tripped, BOP Bus 20 will fail to auto transfer to the SAT. DG3 will auto start and energize E3. DG1 will auto start on Loss BOP Bus 20 with UAT de-energized.

Loss of BOP Bus 20 will require entry into OAOP-36.1 and causes a loss of FW injection.

Reactor water level will drop due to the inventory loss through the leak. Event 10 If level drops to the LL2 initiation, RCIC will fail to auto initiate, but can be manually started. With RCIC injection maximized, LEP-01 alternate coolant injection systems, along with SEP-09 CRD flow maximized (RB inaccessible)

RPV level will be maintained above TAF. Event 11 Area temperatures and water levels will rise. South Core Spray will exceed Max Normal, then Max Safe Operating Water Level. Then South RHR will exceed Max normal then Max Safe Operating Water Level. The crew is directed to consider anticipating emergency depressurization as soon as EOP-03-SCCP directs inserting a manual scram. If the crew does not anticipate emergency depressurization (rapid depressurization to the main condenser) a second area will exceed Max Safe Operating Water Level requiring Emergency Depressurization.

Event 12 Once the reactor is depressurized and RPV level is being maintained

+170-200", the scenario may be terminated.

Suppression Chamber to Drywell Vacuum Breaker D indication is unavailable.

PT-02.3.1A, Vacuum Breaker Position Check Alternate Method has been completed.

The crew will vent the DrywelllAW 20P-10 Section 8.2. Event 2 RCIC will inadvertently initiate.

The crew should respond per OAOP-03.0 and trip RCIC. Event 3 230 kV Line 30 will trip. The Load Dispatcher will request power be reduced to <800 MWe. Power must be reduced using ENP-24.5.

Event 4 The B RBCCW pump will trip with the standby pump failing to auto start. OAOP-16.0 should be entered and the standby pump started to recover system pressure.

Event 5 The HPCI logic power fuse will blow requiring HPCI AOP to be secured per the APP and declared Inoperable.

With RCIC also Inoperable, Tech Specs requires a plant shutdown.

Event 6 The SAT will trip resulting in loss of Recirculation Pumps requiring a manual scram. Manual scram push button B will fail. Rods can be inserted using ARI. Off-site power is lost when the turbine trips. Diesel Generator

  1. 3 will start, tie to E3, then trip on over current. Diesel Generator
  1. 4 will fail to auto start and tie, but can be manually auto started and manually tied to energize E4. The crew will respond per AOP-36.1 and EOP-01-RSP.

Bus E3 cannot be cross-tied due to the electrical fault, but 480V E7 can be cross-tied to E8. SRVs will be available for pressure control. RCIC can be restarted with an initiation signal following trip to provide inventory makeup to the RPV. CRD flow can be maximized (1 pump) and SLC can be aligned for demin water injection (1 pump until E7 is cross-tied, then both). Event 7 A small Recirculation line break will occur. Available injection sources will be unable to stabilize RPV level. RPV level will drop to LL3 resulting in actuation of ADS timers. The crew may allow ADS to automatically initiate, or manually initiate ADS when level drops below TAF. Low pressure ECCS initiation logic will fail at LL3 requiring manual actions to start available pumps and align injection when RPV pressure drops below 400 psig. Event 8 When the RPV has been depressurized and RPV level restored to the normal band, the scenario may be terminated.

Event 1 Continue with startup to -62% power using recirc flow. Event 2 Places the second reactor feed pump in service. Event 2a Annunciator A-04 1-1, Drywell Equip Drain Sump Lvi Hi, will annunciate and the sumps will not auto start. One of the sump pumps will need to be manually started. Event 3 Power to the Main Stack Rad Monitor will be lost. The power results in Group 6 isolation and Secondary containment isolation.

Event 4 TCC Pump 2B will trip and TBCCW low header pressure will alarm. The crew will respond per OAOP-17.0 and place 2C TBCCW pump in service. Event 5 The main turbine lube oil controller will fail closed causing the lube oil to heat up and vibrations to occur on the main turbine. This will require the main turbine to be tripped (>12 mils on bearing 1-8 and >10 mils on bearings 9/10) and the reactor to be scrammed.

Event 6 Most control rods will fail to insert on the scram. The crew will respond to the A TWS per EOP-01-LPC.

Event 7 When SLC initiation is attempted, neither SLC pump will start due to switch failure. The crew will enter LEP-03 and align for alternate boron injection using CRD. Event 8 When scram jumpers are installed the scram discharge vents and drains will fail to open which will result in inability to insert control rods by resetting RPS and inserting additional manual scrams. Event 9 When level has been lowered and level band has been established, the scram discharge volume vents and drains will be repaired.

Control rods can then be inserted by manual scram. When all control rods are inserted and level is being maintained 170 to 200 inches the scenario may be terminated.

Reactor startup is in progress per GP-03. GP-10 sequence A2X is complete up to Step 10 Item 166. Event 1 The crew will continue raising power by pulling control rods in preparation for placing the Mode switch to RUN. Rods pulls will commence at Step 166 (10-23 @ 12) of the A2X sequence.

While withdrawing control rod 10-23 from position 12, IRM C will fail upscale causing a rod block and half scram. SRO will address IRM A and C inoperability lAW TS 3.3.1.1. Once addressed, I&C will report IRM A is ready to be returned to service following proper channel check. The crew will take the actions of the APP and bypass IRM C and reset the half scram. Event 2 Maintenance will contact the control room and request SPEs be swapped due to low oil level. Shift Steam Packing Exhausters (SPE) lAW 20P-26.1, Section 8. Event 3 Following SPE shift, control rods will continue to be withdrawn raising power. Event 4 When control rod 26-23 is selected for withdrawal, it will be stuck at position 12. AOP-02 may be entered and 20P-07, Section 8.2 actions are required to withdraw a difficult intermediate control rod. Event 5 When control rod 26-23 is fully withdrawn, HCU 30-07 accumulator light and annunciator will alarm. AO will be dispatched to investigate and determine accumulator alarm is due to low pressure and requires charging.

TS 3.1.5 evaluation will be required.

Event 5a When HCU 30-07 accumulator is re-pressurized and TS addressed, The TM-25 actuator will fail on 2A RFP. The crew will raise the discharge pressure of the idling RFP and open the discharge valve to maintain level lAW OAOP-23.0.

Event 6 After the TM-25 Actuator failure a spurious Group 1 isolation (MSIV closure) causes reactor pressure and power rise. Manual SRV opening or Scram may be performed.

HPCI and/or RCIC may be manually started to control RPV water level due to loss of RFPTs. Event 7 2 minutes following MSIV closure, SRV F will fail open requiring entry into OAOP-30.0 to attempt to close. Event 8 With SRV F failed open, PCCP will be entered and as reactor pressure falls below 700 psig, the tail pipe will rupture causing direct pressurization of the Suppression Pool air space (loss of PSP). Event 9 When containment spray is attempted with RHR Loop A, the Spray logic will fail to actuate, making sprays unavailable.

Emergency depressurization will be required due to pressure suppression pressure limit. Logic will be available following ED. Event 10 When containment spray is attempted with the B RHR Loop, the E11-F028B will trip on thermal overload.

RHR Loop B will be the only loop available to provide OW Spray lAW SEP-02. Emergency depressurization will be required due to pressure suppression pressure limit. Valve will be available following ED. Event 11 Once the reactor is depressurized with OW & SP Sprays in service and RPV water level being maintained in the normal band, the scenario may be terminated.

Objectives:

seo Directs actions Emergency Depressurization and restoration of reactor water level. Direct drywell and torus spray per SEP-02 and SEP-03 following level restoration.

ROIBOP Performs actions for emergency Depressurization and restoration of reactor water level. Places RHR Loop A in Suppression Chamber and DW spray Success Path: Restore reactor water level to 170-200 inches. RHR Loop has been placed in SP & DW Sprays Simulator Operator Actions: Instructor Activities o Following emergency depressurization actions and by direction of the Lead examiner, DELETE K1227A overrides and contact the control room as I&C to report RHR A Spray logic has been repaired.

o Following emergency depressurization actions and by direction of the Lead examiner, DELETE Q1717LGN, RRN,& ZA358 overrides and report as AO the thermal overload has been reset for the E 11-F028B.

o When RPV level is being controlled above170" with DW & SP spray in service, the scenario may be terminated o When directed by the lead evaluator, place the simulator in FREEZE. Required Operator Actions Emergency Depressurize the RPV (Critical Task) SRO Time Action Notes Determine Emergency Depressurization is required.

Direct placing 7 ADS valve switches to open. (Critical Task) Direct RPV level be restored and maintained

+170-200 inches Evaluate level instruments lAW Caution 1. Page 31 of 34 EVENT 11 cont'd EMERGENCY DEPRESSURIZATION, CONTAINMENT SPRAY SRO (Cont'd) Time Action Notes Directs controlling condensate injection when RPV pressure is less than 440 psig. Directs controlling Low Pressure EGGS injection when RPV pressure is less than 400 psig Directs OW and SP spray when level is being controlled.

RO/BOP Time Action Notes Places 7 ADS valve control switches (Critical Task) Operates LP EGGS to restore and maintain RPV level 170-200 inches. Re-align RHR for LPGI injection.

Ensures Drywell Sprays / SP Sprays / Torus Gooling removed from service Low Pressure EGGS systems may be overridden to prevent uncontrolled injection.

Termination Cue When RPV water level is being maintained above 170 inches with a Loop of RHR spraying the OW and Suppression Pool, by direction of the Lead examiner, the scenario may be terminated.
