Page 3 of 33 Facility: LaSalle County Generating Station Scenario #: Scenario 1 PURPOSE To evaluate the ILT candidates ability to operate the plant in normal, abnormal, and emergency conditions.

SUMMARY

OF EVENTS

1. Perform Standby Gas Treatment Inservice test IAW LOS-VG-M1.

2. RCIC will spuriously initiate requiring the crew to secure RCIC IAW LOP-RI-03. The US will evaluate TS 3.5.3 and 3.3.5.3.

3. CRD Flow Control Valve will fail closed requiring the crew to place the Flow Controller in Manual to restore parameters.

4. The 1A Isophase Bus Duct Cooling fan will trip requiring the crew to start the standby fan per the alarm response procedure.

5. The 1W MPT Transformer will alarm on high temperature >120°C requiring the crew to reduce power for transformer loading.

6. The 1A Reactor Recirculation Pump Flow Control Valve will drift open requiring the crew to lock up the FCV. The US will evaluate TS 3.4.1 and will enter TS 3.4.1 if RR jet pump flows are >5.425 Mlbm/hr mismatch.

7. A small RR LOCA will develop in the drywell requiring the crew to insert a manual scram and initiate Suppression Chamber Sprays.

8. The HPCS pump will fail to auto-start on high drywell pressure requiring the crew to manually start the pump.

9. The SAT will trip 30 seconds after the manual scram. This will cause the MSIVs to close directing all heat from the RPV to the primary containment. Further, this will remove all high-pressure injection systems expect HPCS.

CRITICAL TASKS

1. Initiate Chamber sprays prior to Drywell sprays IAW LGA-003 to minimize the impact of chugging in the downcomers.

2. With MSIVs closed and all decay heat from the RPV going into Primary containment, start Suppression Pool cooling prior to Suppression Pool Temperature reaching 110F.

3. With a failure of HPCS to start automatically on high drywell pressure, manually start HPCS prior to RPV level reaching TAF.

SUMMARY

OF EVENTS

1. ATC NSO will insert control rods to 61% rod line for RR Pump Downshift.

2. Startup the RR LFMG Sets per LOP-RR-08.

3. The crew will downshift the RR Pumps IAW LOP-RR-08.

4. The 1A GC Pump will trip and the standby fails to auto-start requiring the crew to manually start the 1B GC Pump.

5. Rod 46-31 will start drifting out requiring the crew to insert the control rod and maintain the insert button depressed.

6. The 1A CRD Pump will trip requiring the crew to immediately start the 1B CRD Pump.

7. LPCS will spuriously initiate requiring the crew to secure the pump and place it in PTL.

8. A leak will occur from RWCU into secondary containment. The leak will fail to isolate and drive RB temps above max normal requiring the crew to insert a manual scram prior to reaching max safe.

The Main Turbine will fail to trip on reverse power requiring the crew to manually trip the Turbine.

9. The RWCU leak will drive two areas above max safe in the RB requiring the crew to initiate an Emergency Depressurization. Two ADS SRVs will fail to open requiring the crew to manually open two additional SRVs for a total of seven SRVs open.

CRITICAL TASKS

1. With a primary system discharging into the secondary containment, and discharge cannot be isolated or isolation attempt failed, scram the reactor prior to radiation or temperature in any area exceeding Max safe.

2. With conditions present to Emergency Depressurize IAW LGA-002 based on two areas trending towards max safe, blowdown using anticipation of blowdown or Emergency Depressurization within 10 minutes of two areas exceeding Max Safe temperatures.

With a failure of two bypass valves to open resulting in the majority of RPV heat going into primary containment, suppression pool cooling must be established to ensure suppression pool temperature does not exceed the limits of the HCTL curve in LGA-010.

With an ATWS and the RPV discharging into primary containment, action must be taken to shut down and maintain shutdown the reactor before suppression pool temperature exceeds the limits of the HCTL curve in LGA-010.

During an ATWS with Reactor Power above 3% or unknown, initiate SBLC within 16 minutes with an early failure.

SUMMARY

OF EVENTS

1. Swap from B to C VR Supply/Exhaust Fans IAW LOP-VR-01.

2. D APRM fails upscale and B RPS fails to half scram. The US will enter TS 3.3.1.1 for the failed APRMs.

3. 1A Post treat rad monitor fails downscale resulting in a half-trip isolation on Off Gas.

4. 1B Circ Water Pump trips requiring reactor power to be lowered to maintain condenser vacuum.

5. The Division 1 Battery Charger fails requiring the crew to swap to the standby battery charger IAW LOA-DC-101. The US will enter TS 3.8.4 for the failed battery charger.

6. The 1A WS Pump trips requiring the crew to start the 1B WS Pump IAW LOR-1PM10J-A501.

7. The Main Generator will trip due to an electrical fault resulting in an automatic reactor scram. 2 bypass valves will fail to open resulting in a majority RPV heat going into primary containment initially.

8. The automatic reactor scram will not be successful due to A RPS bus failing to deenergize and ARI failing to insert control rods.

9. The first SBLC pump started will have its relief valve failed resulting in the pump not reaching RPV pressure requiring the crew to swap SBLC pumps.

CRITICAL TASKS

1. With a failure of two bypass valves to open resulting in the majority of RPV heat going into primary containment, suppression pool cooling must be established to ensure suppression pool temperature does not exceed the limits of the HCTL curve in LGA-010.

2. With an ATWS and the RPV discharging into primary containment, action must be taken to shut down and maintain shutdown the reactor before suppression pool temperature exceeds the limits of the HCTL curve in LGA-010.

3. After failure of ARI and with the reactor power still above 3%, inject boron using SBLC after determining the FIRST SBLC pump has failed, within 16 minutes.

SUMMARY

OF EVENTS

1. Perform LPCS full flow test IAW LOS-LP-Q1.

2. LPCS/RCIC Corner Room fan fails requiring LPCS to be secured. RCIC and LPCS will be declared inoperable and TS 3.5.1 and 3.5.3 will be entered.

3. The 1A Group 3 Scram solenoid fuse will blow resulting in a partial half scram requiring crew to replace blown fuse and reset partial half scram.

4. The 1A TDRFP Seal Injection Pump will trip with a failure of the 1B TDRFP Seal Injection Pump to auto-start requiring the crew to manually start the 1B TDRFP Seal Injection Pump.

5. R SRV will fail open and will not close. The US will enter TRM 3.3.d for loss of SRV indication.

6. The second RHR WS pump (1B or 1D) will trip upon starting. Crew may realign system for single pump operations IAW LOP-RH-05. The US will enter TS 3.7.1 for inoperable RHRSW.

7. Multiple MSIVs will fast close resulting in a Group 1 isolation and reactor scram.

8. R SRV Tailpipe will break in the Suppression Chamber airspace resulting in a containment bypass path condition requiring Suppression Chamber and Drywell Sprays to be initiated.

9. The first DW Spray valve (1E12-F016A or 1E12-F016B) will fail to open requiring swapping DW sprays to the other RHR system.

CRITICAL TASKS

1. With a closure of the MSIVs and Drains resulting in all of RPV heat going into primary containment, suppression pool cooling must be established to ensure suppression pool temperature does not exceed the limits of the HCTL curve in LGA-003.

2. Initiate Chamber sprays prior to Drywell sprays IAW LGA-003 to minimize the impact of chugging in the downcomers.
