SUMMARY
Event Description 1
Reactor Building Vent Radiation Monitor A will fail resulting in a Group 6 isolation, Secondary Containment isolation and SBGT initiation. SBGT A will fail to auto start requiring manual action. The crew will address TS.
2 Annunciator A-04 1-1, Drywell Equip Drain Sump Lvl Hi, will annunciate and the sumps will not auto start. One of the sump pumps will need to be manually started 3
A power cell in VFD A will fail. Recirc Pump 2A speed will lower and a speed hold will initiate. Loop flows will be outside mismatch limits. The crew will address TS and reset the speed hold and match loop flows.
4 A tube leak will occur in the main condenser resulting in high conductivity alarms.
The crew will respond per 0AOP-26.0 5
Power should be reduced to 53% for water box removal 6
The water box will be removed from service per 2OP-29.0.
7 A large un-isolable RWCU leak will occur. Crew will enter AOP-5.0 and SCCP. SRO should direct a SCRAM. The south room cooler will not start and the north room cooler will run for 5 minutes and then trip. A cooldown should be established in which the bypass opening jack will fail. The crew should use steam line drains to establish the cooldown.
8 Secondary containment conditions will worsen, forcing the SRO to direct an Emergency Depressurization due to high water levels. Two ADS SRVs will fail to manually open. SRO should direct opening two additional SRVs.
LOI SIMULATOR EVALUATION GUIDE LOIX-029 Rev. 0 Page 6 of 37 3.0 CREW CRITICAL TASKS Description Insert a reactor scram prior to any area reaching its Max Safe Operating Value Perform Emergency Depressurization when two plant areas exceed max safe operating water level.
4.0 TERMINATION CRITERIA When emergency depressurization has been performed and the reactor has been depressurized to <100 psig the scenario may be terminated.

SUMMARY
Event Description 0
The SRO will make a determination of the TS actions for a failure of the C32-LT-N004A failing downscale. (TS 3.3.2.2 - 7 day LCO to place in a trip condition) 1 The crew will transfer BOP 2C and 2D Buses from the SAT to the UAT per OP-50 2
The running ADHR Secondary Loop Pump (RCC Pump D) will trip. The crew will have to start RCC Pump C. Shutdown RCC Pump A. Re-align RCC Pump A for ADHR mode and then start the pump for ADHR. (AOP-38.1 will be entered.
3 The HPCI logic power fuse will blow requiring HPCI to be manually isolated per the APP and declared Inoperable per TS 3.5.1, Condition D.
4 Raise reactor power to ~60% using reactor recirculation flow 5
The master level controller will fail. The crew should either place the master controller in manual, the reactor feed pump controller in manual or place DFCS in manual to control level. (AOP-23) 6 An AOG off gas fire will occur in the guard bed. High temperatures will quickly spread into the charcoal absorber beds. The APPs require bypassing and isolating the AOG system, and initiating a nitrogen purge 7
A Loss of Offsite Power will occur. The crew will respond per 0AOP-36.1. All Diesel Generators will start on the LOOP signal. DG3 will trip on Diff O/C. DG 4 output breaker will fail to auto close. The BOP operator will close DG 4 output breaker to energize bus E4. (AOP-36.1) 8 After scram actions have been completed and level is stabilized, a LOCA will occur in the drywell. The crew will maximize RCIC flow and implement LEP-01 for alternate cooling systems. Level will lower until Emergency Depressurization is required. ADS auto blowdown will not occur. RHR Loop B injection valve E11-F015B will fail to automatically open due to mechanical binding. Annunciator A-03 5-8, RHR B Valves Overload, will be received. The thermal overload may be reset and the valve opened using the control switch.
LOI SIMULATOR EVALUATION GUIDE LOIX-030 Rev. 0 Page 6 of 49 3.0 CREW CRITICAL TASKS Description Close DG4 output breaker to energize E4.

SUMMARY
Event Description 1
In order to swap Condensate pumps the crew will determine that power must be reduced to ~80% (Operating with B & C Condensate pumps, condensate flow is limited to 13,500 gpm). The crew will lower power using recirc.
2 Swap condensate pumps in accordance with 2OP-32. The crew will re-align LOCA/Unit Trip Load Shed switches.
3 The running NSW pump will TRIP on motor overload. The STBY NSW pump will fail to AUTO start. The BOP operator should recognize the failure and manually start the STBY NSW pump. (AOP-18)(TS) 4 APRM 4 will fail upscale resulting in a rod block. The APRM will be declared Inoperable per TS 3.3.1.1. WCC SRO will request APRM TS Actions be taken in order to troubleshoot which requires the APRM mode selector switch to be place in INOP IAW 0OI-18.
5 The Heater Drain Deaerator level control system will fail causing the HD pumps discharge valves to fail full open. The crew will respond per AOP-23.0 stop 1 HD pump before HDD level goes <24 and then use the HD-V57 to control HDD level.
6 Reactor Recirc Pump 2A seal #1 will fail and seal pressures will equalize. Shortly after the seal #1 failure, a seal #2 failure will occur. The crew will respond to the Recirc Pump seal failure and the rising drywell temperature and pressure per 0AOP-14.0. 0AOP-14.0 will direct the Recirc Pump be shutdown and then be isolated. The discharge valve will have thermal overload, can be reset after the crew initiates a reactor scram. A reactor scram signal will occur on high drywell pressure. The auto scram signals will not cause a scram but the manual scram signal will 7
When a scram is inserted due to DW pressure an ATWS will occur. Scram discharge volume vents and drain fail closed on the scram, SLC flowpath will have blockage requiring alternate boron injection. Rods will be able to be driven in with RMCS 8
When actions are taken to control reactor water level during the ATWS after terminating and preventing, the SDV vents and drains will be repaired and rods can be inserted
LOI SIMULATOR EVALUATION GUIDE LOIX-031 Rev. 0 Page 6 of 47 3.0 CREW CRITICAL TASKS Description Inserting a manual reactor scram when an auto scram signal is received and the reactor does not scram.
Terminate and prevent HPCI/Feedwater during the ATWS (CS/RHR if LOCA signal received) to lower reactor water level to 90 inches or until all control rods are inserted.
Direct LEP-03, Alternate Boron Injection.
Perform LEP-02, Alternate Rod Insertion, to insert all control rods.
4.0 TERMINATION CRITERIA When all rods are inserted and level is being controlled above TAF the scenario may be terminated.

LOI SIMULATOR EVALUATION GUIDE LOIX-032 Rev. 0 Page 5 of 51 2.0 SCENARIO DESCRIPTION
SUMMARY
Event Description 1
The crew will continue raising power by pulling control rods in preparation for placing the Mode switch to RUN. Rod 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 IAW 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.
2 The running CRD pump will trip and the crew will start the 2B CRD Pump IAW 2OP-
- 08.
3 Maintenance will contact the control room and request SPEs be swapped due to low oil level. Shift Steam Packing Exhausters (SPE) IAW 2OP-26.1, Section 8.
4 Power to the Main Stack Radiation Monitor will fail. The loss of power will result in a Group 6 Isolation signal, but the Reactor Building Ventilation will fail to isolate and must be manually isolated. Technical Specifications will be addressed. AOP-12 will be entered.
5 Control rods will continue to be withdrawn raising power. When control rod 26-23 is selected for withdrawal, it will be stuck at position 12. AOP-02 may be entered and 2OP-07, Section 8.2 actions are required to withdraw a difficult intermediate control rod.
6 The SULCV will fail closed stopping feed flow to the vessel. Reactor water level will drop requiring action to re-establish flow to the vessel.
7 When level control has been established, multiple control rods will drift. The RO will insert a manual reactor scram IAW the requirements of AOP-02.
8 SRV F will fail open. AOP-30 will be entered. The SRV will not reset using the control switch. Pulling fuses IAW AOP-30 results in loss of indication but the SRV remains open. SRV F tailpipe will rupture, pressurizing containment. Emergency Depressurization is required.
LOI SIMULATOR EVALUATION GUIDE LOIX-032 Rev. 0 Page 6 of 51 3.0 CREW CRITICAL TASKS Description Insert a manual Reactor Scram when more than 1 control rod is drifting.
Emergency Depressurize the RPV when PSP has been exceeded.
4.0 TERMINATION CRITERIA When control rods are inserted, the Reactor is depressurized, level is being restored to normal band, and Containment and Drywell Sprays are being place in service, the scenario may be terminated.
