19-1 NRC Exam Scenario 1 Revision 00 Facility: LaSalle County Generating Station Scenario #: 19-1 NRC Exam Scenario 1 PURPOSE Examine the ILT candidates ability to operate the plant in normal, abnormal, and emergency conditions.

SUMMARY

OF EVENTS

1. The crew with perform LOS-HP-Q1.

2. With HPCS running, the pump breaker will trip requiring the crew to place HPCS in a shutdown lineup and enter TS 3.5.1.

3. Gland seal steam PCV will fail requiring the crew to place main steam on gland sealing steam.

4. With a minor leak on 1B steam jet air ejector, the crew will lower power to recover backpressure.

5. An oil leak on 1A TDRFP will require the crew to trip the 1A TDRFP and verify operation of the MDRFP.

6. The 1B RR FCV will fail closed and the FCV lockup pushbutton will also fail initially if depressed immediately.

This will require the crew to take action per LOA-RR-101 and enter TS 3.4.1.

7. The SJAE leak will increase, requiring a manual scram.

8. A hydraulic ATWS will occur requiring the crew to enter LGA-010.

9. The crew will take action to initiate SBLC to combat the ATWS, the first SBLC pump discharge relief valve will fail open, requiring the crew to swap SBLC pumps.

Critical Tasks

1. 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.

2. With a reactor scram required and insufficient control rod worth inserted to maintain the reactor shutdown under all conditions without boron, inhibit ADS prior to ADS auto initiation to prevent an uncontrolled RPV depressurization, causing a significant power excursion.

3. During an ATWS with reactor power above 3%, rapidly lower RPV water level to at least -60 inches within 16 minutes and not to go below -150 inches as indicated on WR level indication.

19-1 NRC Exam Scenario 2 Revision 00 Facility: LaSalle County Generating Station Scenario #: 19-1 NRC Exam Scenario 2 PURPOSE Examine the ILT candidates ability to operate the plant in normal, abnormal, and emergency conditions.

SUMMARY

OF EVENTS

1. The crew will withdraw all IRMs as directed per the turnover and LGP-1-1.

2. When withdrawing IRMs, the F IRM will stick and require the crew to bypass the stuck IRM IAW LOA-NR-101.

3. The crew will withdraw control rods per LGP-1-1 and LOP-RM-01 until 1 1/2 bypass valves are open.

4. The 1A VT Exhaust Fan will trip, requiring the crew to start the 1C VT Exhaust Fan

5. A control rod will drift out, requiring the crew to take action per LOA-RD-101, to insert the control rod and enter Tech Specs.

6. RCIC will spuriously initiate, requiring the crew to secure RCIC and enter Tech Specs.

7. A leak will occur in the RCIC system that will require and isolation. The isolations will fail both manually and automatically requiring a scram per LGA-002. With two areas above max safe, blowdown per LGA-004 will be required.

8. With ADS initiated, only 3 SRVs will open requiring the crew to manually open 4 SRVs.

Critical Tasks

1. With a steam leak in the RCIC Room and the temperature and radiation levels trending toward the max safe values, the crew will scram the reactor IAW LGA-002 before reaching any area radiation/temperature max safe value.

2. With a steam leak in the RCIC Room, temperature and radiation levels will reach the max safe values in the RCIC Room and LPCS Ventilation. The crew will wait until two or more areas are above the max safe value of the same parameter (in the RCIC Room and LPCS Ventilation) to transition to LGA-004 to blowdown within 20 minutes.

3. With blowdown required by LGA-002, the crew will initiate blowdown per LGA-004. When the crew manually initiates ADS, only 3 of the required 7 ADS valves will open. The crew will manually open SRVs, one at a time, until 7 SRVs are open within 10 minutes of manually initiating ADS.

Operations Representative Date

19-1 NRC Exam Scenario 3 Revision 00 Facility: LaSalle County Generating Station Scenario #: 19-1 NRC Exam Scenario 3 PURPOSE Examine the ILT candidates ability to operate the plant in normal, abnormal, and emergency conditions.

SUMMARY

OF EVENTS

1. The crew will synchronize the main generator to the grid per LOP-TG-02.

2. The crew will raise reactor power per the turnover using control rods per LGP-1-1 step E.7.6.

3. Due to a failure of the manual initiation logic, the SBGT system to auto start. Once started, the primary fan will indicate a low flow condition and require a system shutdown and Tech Specs to be entered.

4. A loss of A RCMS Interface will occur, causing the crew to take actions to reset per LOA-RM-101.

5. A VC Rad Monitor will fail, causing the Unit Supervisor to enter Tech Specs.

6. The MDRFP flow instrument will fail upscale requiring the crew to take manual control and open the min flow valve.

7. Main Turbine vibrations will rise, causing the crew to initiate a turbine trip. With a turbine/generator trip, OCB 10-11 will fail to auto trip and must be manually tripped.

8. A leak will develop in the A MSL to the MST causing LGA-002 entry and scram.

9. With a leak from A MSL the crew will attempt to isolate the leak by closing MSIVs and drains. Both A line MSIVs will fail to close.

10. With a high offsite release due to a failure of 1VT79A/B/C, the crew will perform an RPV blowdown per LGA-004.

Critical Tasks

1. Scram the reactor prior to one reactor building designated area (MSL Tunnel) temperature reaching its Maximum Safe value.

2. With a primary system discharging outside primary and secondary containment, manually scram the reactor if a reactor scram has not yet been initiated, enter LGA-001, and INITIATE emergency depressurization before offsite release rate reaches the General Emergency level (8.26 E9).

19-1 NRC Exam Scenario 4 Revision 00 Facility: LaSalle County Generating Station Scenario #: 19-1 NRC Exam Scenario 4 PURPOSE Examine the ILT candidates ability to operate the plant in normal, abnormal, and emergency conditions.

SUMMARY

OF EVENTS

1. The crew will swap from 1B WT pump to 1A WT pump per LOP-WT-02.

2. The 1A RT Pump will trip requiring the crew perform a 5 minute flush and start the 1B RT pump per LOA-RT-101 and LOP-RT-02.

3. HPCS will spuriously start due to a failure of the Level 2 instrumentation and the crew will secure HPCS and enter Tech Specs.

4. A loss bus 138 due to a contractor knocking the breaker, the crew will re-energize bus 138.

5. A failure of the level instrumentation will cause the 16A heater to isolate and the crew to reduce power per LOA-HD-101.

6. A leak in the motor of the 1A RR pump will require the crew to trip the RR pump and enter Tech Specs.

7. A large break in the feedwater system inside the drywell with a bypass path will cause the crew to scram and take action per LGA-001 and LGA-003.

8. With a scram required, RPS B will fail, requiring the crew to insert rods using ARI.

9. With ECCS signals present, LPCS will fail to auto start, requiring the crew to manually start LPCS to maintain RPV level.

Critical Tasks

1. In LGA-003, Primary Containment Control, with suppression chamber pressure above 12 psig, containment flood level below 722 feet, and drywell parameters below the Drywell Spray Initiation Limit; trip all recirculation pumps and start drywell sprays using RHR pumps not needed for adequate core cooling prior to 60 psig drywell pressure.

2. With a Scram signal present and the reactor not shutdown, commence inserting control rods (ARI) prior to Suppression Pool temperature exceeding 110 degrees F.

3. In LGA-003, Primary Containment Control, with suppression chamber pressure above the Pressure Suppression Pressure (PSP) and unable to restore, blowdown IAW LGA-004, RPV Blowdown using ADS prior to 60 psig drywell pressure.
