Scenario Event Description NRC Scenario #1 SCENARIO
SUMMARY
NRC #1 The crew will assume the watch at 100% power with no scheduled activities per Operating Instruction (OI) SO23-5-1.7, Power Operations.
The first event is a Pressurizer Spray Valve that fails 25% open. The crew will respond per Annunciator Response Procedures (ARPs) and Abnormal Operating Instruction (AOI) SO23-13-27, Pressurizer Pressure and Level Malfunction. If pressure drops below 2025 PSIA, the SRO will refer to Technical Specifications.
When Pressurizer pressure is normal, the Train A Salt Water Cooling Pump will seize. This will require a transfer to Train B Component Cooling Water System per AOI SO23-13-7, Loss of Component Cooling Water (CCW) / Salt Water Cooling (SWC). The SRO will refer to Technical Specifications.
When CCW and SWC are restored, Control Element Assembly (CEA) #56 will drop into the core. Crew actions are per AOI SO23-13-13, Misaligned or Immovable Control Element Assembly, and include a power reduction as required per procedure. The crew will restore Reactor Coolant System Cold Leg temperature and then continue with a power reduction using AOI SO23-13-28, Rapid Power Reduction.
The SRO will refer to Technical Specifications.
When power has been lowered an additional 3% to 5%, a second CEA (#01) will drop into the core necessitating a manual Reactor Trip. An automatic trip is not initiated as this is not a Targeted CEA.
When the Reactor Trip pushbuttons are depressed, the Reactor Trip Circuit Breakers (RTCBs) will fail to open. This condition creates an Anticipated Transient Without Scram and is remedied by deenergizing 480 Volt Buses B15 and B16 on CR-63 which open the Control Element Drive Mechanism Motor Generator output contactors. The Reactor Trip is complicated by a loss of both Reactor Coolant Pump (RCP) Buses 2A01 and 2A02, High Pressure Turbine Stop Valves that fail to close, loss of Condenser Vacuum, and Motor Driven Auxiliary Feedwater Pumps that fail to start on an Emergency Feedwater Actuation Signal. The RTCBs will eventually open when a bona fide Reactor Protection System signal is received when RCPs are lost.
The crew will perform Emergency Operating Instruction (EOI) SO23-12-1, Standard Post Trip Actions (SPTAs) and then transition to EOI SO23-12-7, Loss of Forced Circulation / Loss of Offsite Power. The scenario is terminated when Natural Circulation is verified per EOI SO23-12-11, EOI Supporting Attachments, Floating Step 3 (FS-3), Monitor Natural Circulation Established.

Scenario Event Description NRC Scenario #2 SCENARIO
SUMMARY
NRC #2 The crew will assume the watch at 100% power with no scheduled activities per Operating Instruction (OI) SO23-5-1.7, Power Operations. When the Shift Turnover is complete, a Pressurizer Pressure Channel fails high. Actions are per Abnormal Operating Instruction (AOI) SO23-13-27, Pressurizer Pressure and Level Malfunction. The alternate controlling channel will be placed in service and Pressurizer Heaters will be restored to operation. If pressure drops below 2025 PSIA, the SRO will refer to Technical Specifications.
When Technical Specifications have been referenced, a Steam Generator Pressure Channel fails low.
The crew will respond per AOI SO23-13-18, Reactor Protection System Failure, and OI SO23-3-2.38, Digital Control System Operation. Steam Generator Pressure trips will be bypassed in the Reactor Protection System and the Feedwater Control System. The SRO will refer to Technical Specifications.
The next event is a low failure of the Letdown Temperature Control Valve (TCV) Transmitter. Letdown temperature quickly rises, causing a high temperature alarm, with a failure of automatic actions to isolate the Boronometer. The crew will respond per the Annunciator Response Procedures (ARPs) to manually satisfy the automatic actions and restore Letdown temperature to normal. The TCV will remain in MANUAL.
When Letdown temperature is stable, a loss of Train A 1E Bus 2A04 will occur due to an overcurrent trip and lockout. The crew will enter AOI SO23-13-26, Loss of Power to an AC Bus. Crew actions include placing a Charging Pump in service, transferring to the Train B Component Cooling Water System, initiating Train B Toxic Gas Isolation System, and starting a Containment Dome Air Circulating Fan. The SRO will refer to Technical Specifications.
When conditions are stable, a Loss of Offsite Power will occur. The crew will enter Emergency Operating Instruction (EOI) SO23-12-1, Standard Post Trip Actions (SPTAs), and perform actions to stabilize the plant. During the trip, three Control Element Assemblies will be stuck, Train B Emergency Diesel Generator (EDG) will fail to start, and the Turbine Driven Auxiliary Feedwater (TDAFW) Pump will fail to start on the Emergency Feedwater Actuation Signal (EFAS). The SRO will recognize a Loss of Reactivity Control, Station Blackout, and Loss of Feedwater requiring entry into EOI SO23-12-9, Functional Recovery.
The Loss of Feedwater event is remedied by manually starting P-140, TDAFW Pump. The Station Blackout cannot be remedied until power is available, therefore, reenergizing the 1E 4 kV Bus is a priority and is accomplished by cross connecting with the Unit 3 Train B Emergency Diesel Generator.
The Loss of Reactivity Control is remedied by Reactor power level lowering below 1x10-4% power. The crew may opt to initiate Emergency Boration when 1E Bus power is restored. The scenario is terminated when power is restored to Bus 2A06 and a Charging Pump and Component Cooling Water Train are returned to service.
Risk Significance:
- Failure of risk important system prior to trip: Loss of 1E 4160 Volt Bus 2A04
- Risk significant core damage sequence: Loss of Reactivity Control Station Blackout / Loss of Feedwater Flow
- Risk significant operator actions: Restore Flow to Non-Critical Loop Restore Power to 4160 Volt Bus 2A06 SONGS 2011 NRC Sim Scenario #2 Rev f.doc

Scenario Event Description NRC Scenario #3 SCENARIO
SUMMARY
NRC #3 The crew will assume the watch at 100% power with no scheduled activities per Operating Instruction (OI) SO23-5-1.7, Power Operations.
The first event is a trip of the running Component Cooling Water (CCW) Pump P-025. The crew will attempt to start the standby Train A CCW Pump P-024, however, this pump also fails to start. Operator actions are per Abnormal Operating Instruction (AOI) SO23-13-7, Loss of Component Cooling Water/Salt Water Cooling. The crew will transfer CCW to Train B along with the Non-Critical Loop and Letdown Heat Exchanger. The SRO will refer to Technical Specifications.
When the plant systems are stable, Linear Power Channel C will fail low. The crew will refer to AOI SO23-13-18, Reactor Protection System Failure / Loss of Vital Bus. The RO will determine the affected instrument by operating the Channel C Core Protection Calculator ROM Station. Once identified, the affected Channel C trips will be bypassed. The SRO will refer to Technical Specifications.
When the channel is bypassed, a partial loss of Condenser vacuum will occur. The crew will respond per the Annunciator Response Procedures (ARPs) and AOI SO23-13-10, Loss of Condenser Vacuum and lower power level until the Turbine Vacuum Limit is in the Area of Unrestricted Operation. Once power level is reduced, the source of the vacuum leak will be located and Condenser vacuum will be restored.
When plant parameters are stable, Steam Generator E-088 Master Controller Setpoint slowly fails to 45%. Entry into SO23-13-24, Feedwater Control System Malfunction is required. Steam Generator level control is restored by placing the Master Controller in MANUAL and will remain in this position until the Main Steam Line break occurs.
When control of level is established, a Main Steam Line break will occur inside Containment on Steam Generator E-088. The crew will enter Emergency Operating Instruction (EOI) SO23-12-1, Standard Post Trip Actions (SPTAs) and then transition to EOI SO23-12-5, Excess Steam Demand Event (ESDE).
Procedure entries include EOI SO23-12-11, EOI Supporting Attachments, Floating Step 30 (FS-30),
Establish Stable RCS Temperature during ESDE, which is required to stabilize Reactor Coolant System (RCS) temperature when E-088 dryout is reached or pressure lowers below 200 PSIG.
This scenario is complicated by a failure of Train B Safety Injection Actuation System valves to open, a Train A Containment Spray Pump start failure, and a Main Steam Isolation Signal that fails to actuate.
This scenario is terminated when RCS Cold Leg temperature has been stabilized per FS-30 and the affected Steam Generator isolated per SO23-12-5, Excess Steam Demand Event.
Risk Significance:
- Failure of risk important system prior to trip: Loss of Component Cooling Water
- Risk significant core damage sequence: ESDE Inside Containment

Scenario Event Description NRC Scenario #4 SCENARIO
SUMMARY
NRC #4 The crew will assume the watch at 100% power with no scheduled activities per Operating Instruction (OI) SO23-5-1.7, Power Operations. When the Shift Turnover is complete, a Pressurizer Pressure Channel fails low. Actions are per the Annunciator Response Procedures (ARPs) and Abnormal Operating Instruction (AOI) SO23-13-27, Pressurizer Pressure and Level Malfunction. The alternate controlling channel will be placed in service and Pressurizer Heaters will be restored to operation. If pressure rises above 2275 PSIA, the SRO will refer to Technical Specifications.
When conditions are stable, a tube leak will develop on the Train A Component Cooling Water (CCW)
Heat Exchanger. The crew will respond per AOI SO23-13-7, Loss of Component Cooling Water /
Saltwater Cooling. Crew actions include transferring to the Train B Component Cooling Water System as well is attempting to isolate the Train A leakage. The SRO will refer to Technical Specifications.
When CCW actions are complete, a Control Element Assembly Calculator (CEAC) will fail. The crew will perform actions per the ARPs and OI SO23-3-2.13, Core Protection / Control Element Assembly Calculator Operation. The SRO will refer to Technical Specifications.
The next event is a trip of Main Feedwater Pump P-062. The crew will reference AOI SO23-13-28, Rapid Power Reduction. A Rapid Power Reduction is performed to reduce Main Turbine load to 70%.
Actions include a Boration to the Charging Pump suction per OI SO23-3-2.2, Makeup Operations and insertion of Control Element Assemblies per OI SO23-3-2.19, Control Element Drive Mechanism Control System Operation.
When power is stable at 70%, a second Main Feedwater Pump will trip requiring a manual Reactor trip.
The crew will enter Emergency Operating Instruction (EOI) SO23-12-1, Standard Post Trip Actions (SPTAs), and determine that two Control Element Assemblies have failed to insert and requiring an Emergency Boration.
The scenario is complicated with a failure of Non-1E Bus 2A07 to AUTO transfer on Reactor Trip. The Motor Driven Auxiliary Feedwater Pumps will operate for two minutes prior to tripping and the Turbine Driven AFW Pump will trip after five minutes rendering a total Loss of Feedwater Flow.
The crew will transition from EOI SO23-12-1, SPTAs, to EOI SO23-12-6, Loss of Feedwater. When the Reactor Coolant Pumps are secured in EOI SO23-12-6, the Turbine Driven Auxiliary Feedwater Pump overspeed trip will be reset per EOI SO23-12-11, EOI Supporting Attachments, FS-11, Reset P-140 Overspeed Trip.
The scenario is terminated when Auxiliary Feedwater System flow is restored to either Steam Generator.
Risk Significance:
- Failure of risk important system prior to trip: Train A CCW Heat Exchanger

SUMMARY
NRC #5 The crew will assume the watch at 100% power per Operating Instruction (OI) SO23-5-1.7, Power Operations. Scheduled activities include performance of Return-to-Service testing of Containment Sump Pump P-008 per OI SO23-2-16, Operation of Waste Water Systems.
When the Containment Sump is pumped, a Steam Generator Level Transmitter will fail low. The crew will determine level instrument failure per Annunciator Response Procedures (ARPs), enter Abnormal Operating Instruction (AOI) SO23-13-18, Reactor Protection System Failure, and be required to bypass the failed signal using SO23-3-2.38, Digital Control System Operation. The SRO will refer to Technical Specifications.
When bypassing is complete, the controlling Pressurizer Level Channel will fail high. Actions are per the ARPs and AOI SO23-13-27, Pressurizer Pressure and Level Malfunction. This event is complicated by a Train B 1E Pressurizer Heater overcurrent trip. The SRO will refer to Technical Specifications.
Once Technical Specifications are addressed, the running Nuclear Service Water (NSW) Low Pressure Pump will trip. The standby NSW High Pressure Pump will fail to AUTO start and require manual actions as outlined in the Annunciator Response Procedures.
When NSW flow is restored, an Operating Basis Earthquake will occur which is immediately followed by an inadvertent Turbine trip. The Reactor will fail to trip upon Turbine trip and require manual actions by the crew. A Small Break Loss of Coolant Accident, failed fuel, and an Excess Steam Demand Event (ESDE) inside Containment are initiated when the Reactor is manually tripped.
The crew will enter Emergency Operating Instruction (EOI) SO23-12-1, Standard Post Trip Actions (SPTAs), and then transition to EOI SO23-12-9, Functional Recovery. Recovery actions include entry into EOI SO23-12-11, EOI Supporting Attachments, Attachment 29, Isolation of Steam Generator with ESDE, and FS-30, Establish Stable RCS Temperature during ESDE.
This scenario is complicated by failure of the Train B Component Cooling Water and High Pressure Safety Injection Pumps to automatically start upon a Safety Injection Actuation Signal (SIAS).
Additionally, the Train A High Pressure Safety Injection Pump (P-018, Swing Pump) will overcurrent trip upon SIAS.
The scenario is terminated when Steam Generator E-089 is isolated per SO23-12-11, EOI Supporting Attachments, Attachment 29, Isolation of Steam Generator with ESDE.
Risk Significance:
- Failure of risk important system prior to trip: Loss of Train B 1E Pressurizer Heaters

SUMMARY
NRC #6 The crew will assume the watch with Reactor power at 4% per Operating Instruction (OI) SO23-5-1.3.1, Plant Startup from Hot Standby to Minimum Load. The Steam Bypass Control System is in operation controlling Reactor Coolant System temperature.
When Shift Turnover is complete, the Auxiliary Feedwater System will be placed in Standby per OI SO23-2-4, Auxiliary Feedwater System Operation. When the Auxiliary Feedwater Pumps are secured, a power increase to 18% using CEAs and Reactor Coolant System Dilution with entry into MODE 1 will be performed.
When power has been raised 3% to 5%, a Reactor Coolant System (RCS) Loop 1 THOT Channel will fail high. Actions are per Abnormal Operating Instruction (AOI) SO23-13-27, Pressurizer Pressure and Level Malfunction. Actions include transferring to an OPERABLE channel, changing the input to the TAVE program, and restoring Pressurizer level.
When Pressurizer level is restored, the running Turbine Plant Cooling Water (TPCW) Pump will trip. The crew will respond per the Annunciator Response Procedures (ARPs) and start the standby TPCW Pump.
When plant conditions are stable, a Refueling Water Storage Tank Level Transmitter fails low. The crew will reference AOI SO23-13-18, Reactor Protection System Failure, and place the failed unit in BYPASS.
The SRO will refer to Technical Specifications.
The next event is a Steam Generator E-089 Tube Leak. Entry into AOI SO23-13-4, Reactor Coolant Leak, will direct the crew to identify the source and quantity of leakage. The SRO will refer to Technical Specifications and based on leakage indications, will direct a Reactor Trip and entry into Emergency Operating Instruction (EOI) SO23-12-1, Standard Post Trip Actions (SPTAs).
When the Reactor is tripped, a Steam Generator Tube Rupture will occur. The event is complicated with a loss of 1E 480 Volt Buses 2B06 and 2B26 and a failure of the Safety Injection Actuation (SIAS) and Containment Cooling Actuation Signals (CCAS). Both signals must be manually initiated from the Control Room and the Train B Emergency Diesel Generator placed in Maintenance Lockout.
Actions to cooldown and isolate the Steam Generator are performed per EOI SO23-12-4, Steam Generator Tube Rupture. During the cooldown, all Reactor Coolant Pumps must be secured and Natural Circulation verified per EOI SO23-12-11, EOI Supporting Attachments, FS-3, Monitor Natural Circulation Established. The scenario is terminated when Reactor Coolant System THOT is lowered below 530°F, the ruptured Steam Generator is isolated, and Natural Circulation is verified.
