Topeka Dispatch/System Operator called to inform Wolf Creek that 345-50 KV Benton line will be removed from service in 20 minutes for four hours. Directive #300 was performed. Per Directive

1. 300 Wolf Creek will be divorced from the Athens line (also opening 69-14 Breaker). Reduce power and decrease turbine load to less than 900 MWE NET.

The Call Superintendent has directed the crew to use OFN MA-038, RAPID PLANT SHUTDOWN to maneuver the unit at a rate of 1%/minute.

Event 1: The Crew commences a power reduction and turbine load reduction to 900 MWE NET (945 MWE GROSS) per OFN MA-038, RAPID PLANT SHUTDOWN at a rate of 1%/minute.

Event 2: Steam Generator D pressure channel AB PT-545 fails low. Meter indications change, and Main Control Board alarms annunciate. ALRs 00-111C, SG D FLOW MISMATCH or 00-111B SG D LEV DEV, may be entered and performed. OFN SB-008, INSTRUMENT MALFUNCTIONS, is entered and Attachment C performed. These procedures diagnose and mitigate the instrument failure.

The Control Room Supervisor determines Technical Specifications.

Event 3: Pressurizer (PZR) pressure channel BB PI-456 fails high. The PZR spray valves close, meter indications change and various Main Control Board alarms annunciate. ALRs 00-034B, PZR PRESS HI, 00-034C, PZR PORV BLOCK; 00-034E, PRT PRESS HI; 00-035B, PORV OPEN; 00-035D, PZR PORV DISCH TEMP HI; 00-083C, RX PARTIAL TRIP annunciate. OFN SB-008, INSTRUMENT MALFUNCTIONS, is entered and Attachment K performed. These procedures diagnose and mitigate the instrument failure.

The Control Room Supervisor determines Technical Specifications.

Event 4: The Main Event is a Large Break Loss of Coolant Accident.

Diagnostics include: PZR level decreases and RCS pressure decreases. OFN BB-007, SG/RCS LEAKAGE HIGH, may be entered & performed. A Reactor trip and Safety Injection occur. EMG E-0, REACTOR TRIP OR SAFETY INJECTION, is entered & performed.

RCPs are tripped per EMG E-0 Foldout page criteria.

The unit is at ~74% power, middle of life. Monitor MFP B vibration. Started the downpower and are currently on HOLD at ~74% waiting an Engineering Evaluation. Annunciator 00-058B, VCT VLV NOT IN VCT POS, due to recent 200-gallon dilution to hold power. Diluting ~100 gallons every 10-15 minutes. No equipment is out of service.

Event 1: RCS Loop A BB TI-411 Tcold fails high. Meter indication changes and the Control Rods insert - the Reactor Operator (RO) places control rods in MANUAL, stopping the insertion.

Many Main Control Board alarms annunciate: 00-065C, 00-065E, 00-066B, 00-067D, 00-068D, 00-069D, 00-082B and 00-083C. OFN SB-008, INSTRUMENT MALFUNCTIONS, is entered and Attachment L performed. This procedure will diagnose and mitigate the instrument failure.

The Control Room Supervisor determines Technical Specifications.

Event 2: Steam Generator C controlling level channel AE LI-553 fails high. Meter indications change and Main Control Board alarms, 00-110A, SG C LEV HI/LO and 00-110B, SG C LEV DEV, annunciate. ALR 00-110A, SG C LEV HI/LO, or 00-110B, SG C LEV DEV, may be entered and performed. OFN SB-008, INSTRUMENT MALFUNCTIONS, is entered and Attachment F is performed. These procedures diagnose and mitigate the instrument failure.

The Control Room Supervisor determines Technical Specifications.

Event 3: Pressurizer Pilot Operated Relief Valve (PORV) BB PCV-455A fails to 25% open due to control circuitry problems. Diagnostic parameters include dual indication on hand indicating switch BB HIS-455A, and alarms 00-035B, PORV OPEN, 00-035C, PZR SFTY DISCH TEMP HI, 00-035D, PZR PORV DISCH TEMP HI, 00-034E, PRT PRESS HI annunciating. ALR 00-035B may be entered and performed to close the PZR Seal Iso Valve using BB HIS-8000A. This action mitigates the event.

The Control Room Supervisor determines Technical Specifications.

Event 4: The Main Event is a Steam line break inside Containment (Steam Generator A).

Diagnostic parameters include Secondary steam flow to feed flow meters mismatch, increasing SG steam flow, Containment pressure and humidity while it decreases Main Turbine load and RCS pressure and temperature. OFN AB-041, STEAMLINE OR FEEDLINE LEAK may be entered. A Reactor trip and Safety Injection occurs. EMG E-0, REACTOR TRIP OR SAFETY INJECTION, is entered and performed. The faulted SG is identified and isolated (EMG E-0 foldout page criteria). Adverse Containment is identified and setpoints for various parameters are used. The Crew transitions to EMG E-2, FAULTED STEAM GENERATOR ISOLATION.

Eventually the Crew transitions to EMG ES-03, SI TERMINATION, to mitigate PZR overfill and RCS high pressure.

Post trip malfunctions:

1. Event 5: LOCA Sequencer A failure at five second time interval frame. This component failure requires the Crew to start ECCS equipment per EMG E-0 Attachment F.

2. Event 6: Main Generator and Exciter breakers fail to automatically trip. This component failure requires the BOP to permit MA HS-5, SWYD 345-50/60 MAN TRIP PERMIT switch, BEFORE opening the breakers per EMG step 6RNO.

Scenario summary:

Unit is at ~ 10 % power, beginning of life. Power ascension in progress, negative MTC. Perform step 6.40 through step 6.46 of GEN 00-003, HOT STANDBY TO MINIMUM LOAD. Use SYS AC-120, MAIN TURBINE GENERATOR STARTUP to synchronize the Main Generator to the grid.

Increase power to ~15% immediately after synchronizing Main Turbine Generator to the grid.

Event 1: The Crew, using GEN 00-003, HOT STANDBY TO MINIMUM LOAD, from step 6.40 through step 6.46 will synchronize Main Generator to the grid, verify valve alignments, increase turbine load using load potentiometer, and verify Permissive states etc.

Event 2: Loss of NN02 occurs. White train meter indications change and many Main Control Board alarms annunciate aid in diagnosing the component failure. The Crew may enter ALR 00-026A, NN02 INST BUS UV. The Crew enters OFN NN-021, LOSS OF VITAL 120VAC INSTRUMENT BUS, and performs Attachment B to restore power.

The Control Room Supervisor determines Technical Specifications.

Event 3: Atmospheric Relief Valve (ARV) C fails PARTIALLY open and manual control is unavailable. The Crew enters OFN AB-041, STEAMLINE OR FEEDLINE BREAK to mitigate the component failure. An Operator is dispatched to locally close the valve.

The Control Room Supervisor determines Technical Specifications.

Event 4: A Seismic event occurs. Main Control Board alarms 00-098D, OBE and 00-098E, SEISMIC RECORDER ON, annunciate. OFN SG-003, NATURAL EVENTS, is entered. The only running Main Feed Pump trips three minutes later. Main Control Board alarm 00-123A, MFP B TRIP, annunciates. The Crew determines a Reactor trip is necessary. A Reactor trip condition occurs; only the reactor fails to trip.

Event 5: The Main Event is an Anticipated Transient Without Trip (ATWT).

The Crew enters EMG E-0, REACTOR TRIP OR SAFETY INJECTION, and from step 1RNO transitions to EMG FR-S1, RESPONSE TO NUCLEAR POWER GENERATION/ATWS.

Event 6: The turbine will not trip manually - the BOP must manually trip the turbine within thirty seconds to prevent an uncontrolled cooldown of the RCS due to steam flow that the turbine would require (2RNO EMG FR-S1 and EMG E-0).

Event 7: When aligning emergency boration, BG HV-8104 does not open. The ATC aligns Refueling Water Storage Tank to charging pump suction instead (6RNO of EMG FR-S1).

Successful mitigation strategy requires the Crew continues performance of EMG FR-S1, RESPONSE TO NUCLEAR POWER GENERATION/ATWS.

FINAL 2 of 4

Post trip malfunction:

1. Event 6: Post trip malfunction #1: The turbine will not trip manually. As part of Immediate Actions of EMG FR-S1, RESPONSE TO NUCLEAR POWER GENERATION/ATWS, step 2RNO, the BOP must trip the turbine.

2. Event 7: Post trip malfunction #2: EMER BORATE TO CHG PUMP SUCT BG HIS-8104 does not open (see step 6 of EMG FR-S1, RESPONSE TO NUCLEAR POWER GENERATION/ATWS). RNO performed: aligns RWST to charging pump suction.

Scenario Critical Tasks (CT):

Event 5: CT: Insert negative reactivity into the core by at least one of the following methods before the Steam Generators dry-out:

• De-energize the control rod drive MG sets

• Manually insert control rods Event 6: CT: Manually trip the turbine to prevent an uncontrolled cooldown of the RCS due to steam flow that the turbine would require.
