Scenario-01 Revision: 00 Date: 12/13/2004 Narrative Summary NRC Scenario-01:

Event Description

1. Initial conditions have the plant returning to full power following a load drop. Power is approximately 93% RTP. The examinees are directed to continue ramping power to 100% using Reactor Recirculation Flow Control Valves.
2. The RCIC drain pot high level alarm will annunciate. The examinees will recognize that the drain bypass valve 1E51-F054 has automatically opened. Following the annunciator procedure, when the high level alarm does NOT clear, they will have to close the RCIC Trip and Throttle Valve 1E51-F360. This will render the RCIC system inoperable and the Unit Supervisor will have to make a Technical Specification determination.
3. The running CRD Pump will trip. Per the annunciator procedure, the NSO will verify that Charging Water Pressure is greater than 500 psig, and then start the standby CRD pump, and follow up with normal operating procedure.
4. This event is a Technical Specification for the Unit Supervisor. The event starts with an annunciator indicating trouble at a heat-tracing panel. When sent to investigate, the NLO discovers that the breaker is tripped and will NOT reset. This makes both the Hydrogen and Oxygen Post-LOCA monitors inoperable. The Unit Supervisor will enter the appropriate time clock to restore the monitors to operable.
5. This event simulates a blow fuse that causes an outboard RR HPU hydraulic isolation valve to fail closed. The RO is expected to follow the annunciator procedures and lockup the associated flow control valve.
6. For this event a Reactor Recirculation line will break causing LOCA conditions in the Drywell. Automatic RPS Scram will fail however manual actions to scram will be successful. The Unit Supervisor will enter the EOPs and take actions to control Reactor Water Level and Drywell Pressure. The MDRFP trips shortly after starting. Bus 143 trips on overcurrent. RCIC is not available from an earlier event. This will require a blowdown for level control. MSIVs close when Mode Switch contacts fail such that the 854 psig interlock is not bypassed.

Termination The scenario can be terminated when the examinees have RPV and Containment parameters stable and under control.

Critical Steps:

1. Manually scram the reactor when or before the automatic setpoint is exceeded.
2. Perform a blowdown per the EOPs when level cannot be restored and maintained above -150 inches.

Scenario-02 Revision: 00 Date: 12/13/2004 Narrative Summary NRC Scenario-02:

Event Description

1. This event is a normal swap of the running CRD pump (from 1A to 1B) per the procedure.
2. Drywell pneumatic trouble alarm is received, an NLO is send to investigate. The NLO reports back to the control room that the South Bottle bank pressure is actually below the alarm setpoint. The Unit Supervisor is expected to make a Technical Specification determination.
3. The running TDRFP Seal Injection Pump will trip and the standby pump will fail to automatically start. The NSO will take actions per the annunciator procedure.
4. Next a CRD HCU Accumulator will alarm. The examinees are expected to dispatch an NLO to the effected HCU. The NLO reports that the accumulator has low pressure. The Unit Supervisor is expected to declare the accumulator inoperable and make a Technical Specification determination.
5. A Heater Drain Pump trips. The RO starts the standby Heater Drain pump.
6. The second Heater Drain Pump trips. The examinees are expected to enter LOA-HD-101 and reduce power. If this is not done before Heater Drain Tank level increases to 9-feet the HD Flushing valves will fully open and the Feedwater Pumps will trip on low suction pressure.
7. Next a LOCA will develop in the Drywell. The event is entered when directed by the lead examiner or immediately if the reactor automatically scrams due to loss of Feedwater. The examinees are expected to enter the EOP based on RPV Level and Containment Pressure.
8. This event is an electrical ATWS when RPS B fails to trip when required.

The examinees are expected to enter LGA-010 and LGA-NB-01 and take actions to shutdown the reactor. When the first fuse is pulled rods will start to move however the SDV will fill and they will have to reset the scram, drain the SDV and re-scram reactor to get rods to go full-in.

Termination Scenario can be terminated when the examinees have Control Rods inserted and Containment parameters stable and under control.

Critical Steps:

1. Reduce power per the abnormal operating procedure following the loss of HD pump forward.
2. Use multiple methods per LGA-NB-01 to insert control rods during an ATWS.
3. Initiate Suppression Chamber and Drywell sprays for containment control.

Scenario-03 Revision: 00 Date: 12/13/2004 Narrative Summary NRC Scenario-03:

Event Description

1. The RO will continue to pull control rods per the startup sequence package.
2. One control rod is determined to be stuck. Several attempts to free the rod using the normal operating procedure (LOP) will fail. The LOP will direct the operator to take actions per the abnormal operating procedure. When drive water pressure is increased sufficiently, the rod will free itself. And the startup can continue.
3. One control rod will start to drift in. The crew will take actions per the abnormal operating procedure and the SRO will make a Technical Specification determination.
4. One of the four Reactor Building Ventilation Fuel Pool Exhaust Radiation Monitors fails upscale. This will cause an annunciator to alarm in the control room. The Unit Supervisor is expected to make a Technical Specification determination.
5. A rupture in the Off-Gas 2nd Stage Air Ejector line will cause a slow loss of vacuum. The crew will have time to dispatch operators to look for air leakage into the main condenser. The size of the leak continues to increase until the crew is forced to manually scram the reactor. When the reactor is scrammed, 3 control rods will stick full-out rendering a low power ATWS.

The RO will be able to close the Drive Water Pressure control valve and then manually drive the three control rods full-in.

6. Next a steam leak LOCA will develop with a containment bypass path.

Termination The scenario can be terminated when the examinees have RPV and Containment Parameters stable and under control.

Critical Steps:

1. Initiate Suppression Chamber Sprays and Drywell Sprays to control containment parameters
2. Use EOP Support Procedures to insert control rods following the scram.

Scenario-03 Revision: 00 Date: 12/13/2004 OSG Validation Checklist Scenario Number: Scenario-03 1._____ Verify that if not run from a protected IC that setup information is provided to reproduce the stated initial conditions.

2._____ Verify that all stated objectives are identified in the body of the OSG.

3._____ Verify that turnover sheets are completed, and are in agreement with both the narrative summary and shift turnover information sheet. Turnover sheets are not required for initial license scenarios.

4._____ Verify that if the scenario requires documents to be provided to the crew, they are filled out as appropriate (i.e., if an LOS is used, it is filled out).

5._____ If this is the initial validation of the revision affects ramp times, event triggers, malfunctions, overrides, remote functions or procedure changes that could affect the scenario, then validate the scenario for proper response using a crew. It is preferable to use a crew unfamiliar with the scenario when ever possible. Verify the following while running the scenario:

  • The scenario runs as written and all tasks are performed.
  • The stated time line agrees with actual times.
  • Critical task statements clearly define the expected plant and student response. They should also be written so that they are achievable as written. If any questions exist, it is preferable to have operations management participate in the validation.
  • Anticipate instructor role-play / cues are identified.
  • Management expectations are captured and re-enforced.
  • Verify administrative documentation requirements (i.e., ARs) are identified.
  • Verify Technical Specifications items / LCO declarations are correct.
  • Verify soft skills expectations are captured and are re-enforced.
  • If procedure steps may cause confusion or disagreement between higher level procedures and LOPs / LORs that operations management is consulted.

6._____ Shutdown scenarios include shutdown risk assessment, time to boil calculations and shutdown status board information.

7._____ QNE review if needed.
