ppendix D Scenario Outline Form ES-D-1 I Scenario 1 Summary Initial Conditions:
The plant is at BOL. A startup is in progress from a forced outage to repair an EHC high pressure piping leak. Power is stable at 2%. GO-3 Section 5.2 step 12 which required the completion of Appendix A (Mode 2 to Mode 1 approval) was just completed. The Operation Superintendents approval to enter Mode 1 was just obtained. The crew is in GO-3 Unit Startup From Less Than 4% Reactor Power to 30%
Reactor Power section 5.3 step 3. The crew is then expected to raise reactor power to between 13% and 15% utilizing control rods.
- 1. Commence a power increase, in accordance with the reactivity plan.
- 2. Auctioneered Tavg fails high. Charging flow rises due to PZR level setpoint failing to 60%. RO manually controls charging lAW AOI-2 Malfunction of Reactor Control.
- 3. 1 A CCS Pump bearing starts to wear to the point it trips on overcurrent. The 1 B CCS Pump fails to auto start on low pressure. BOP manually starts the lB CCS Pump lAW AOl-15, Loss of Component Cooling Water. SRO evaluates Tech Specs.
- 4. Control rod H-12 drops to the bottom of the core. AOI-2, Malfunction of Reactor Control, is entered.
SRO evaluates Tech Specs.
- 5. At Lead Evaluators discretion, control rod C-S drops into the core, requiring reactor trip and E-0 and ES-0.1 entry.
- 6. Main Steam pressure transmitter 1-PT-i -33 fails high resulting in steam dumps opening, requiring BOP action to close lAW ES-0.i.
- 7. Large Break LOCA with failure of both SI trains to automatically actuate and a loss of 1A 6.9 KV Shutdown Board. RO manually actuates SI. Requires entry into E-0 and later E-i.
- 8. Failure of automatic RHR Pump swap over to Containment Sump in ES-i .3, requiring manual actions by RO.
- 9. Just after RO takes manual action to swap suction lB RHR Pump over to Containment Sump in ES-1.3, the lB RHR Pump will trip, requiring transition to ECA-i .1. The scenario will end when the crew has addressed commencing a cooldown at less than 1000 F/Hr.

RXES or designee / Date Ops / Date RXE support required Onsite? DYes No Describe: Simulator Scenario Title of Reactivity Control Plan: Power Escalation for Simulator Assumptions: 1. Criticality is attained with Control Bank D (CBD) at 130 steps
- 2. Power escalation proceeds according to schedule Major Steps: 1. Reactor power raised from HZP to 15% RTP
- 2. Unit is maintained at 15% RTP for 6 hrs
- 3. Unit is ramped to 30% per the schedule
- 4. Unit is maintained 30% for flux map Detailed
Description:
NOTE: See attached plots.
NOTE: Should deviations occur from the projected power ascension profile, particularly delays, there should be no major effects on the predicted parameters. Should delays occur, lower dilution rates could be expected later due to the additional Xenon build-in during the delays.
NOTE: This Reactivity Control Plan only covers power escalation through 30% RTP. A Reactivity Control Plan covering the remainder of the power escalation will be issued prior to completion of the 30% RTP hold.
Power Increase to -159 RTP:
- 1. WITHDRAW CBD to facilitate power rise. (The actual amount of rod withdrawal necessary to attain 15% RTP depends upon the CBD position at criticality.)
- 2. IF CBD has been withdrawn to -165 steps and reactor power has not reached 15%
RTP, THEN DILUTE as necessary to raise power to -15% for synchronization of the Turbine-Generator. (The actual amount of dilution necessary depends upon the CBD position at criticality.)
Operation on Steam Dumps until Generator Synchronization:
- 1. ENSURE CBD has been withdrawn to -165 steps.
- 2. DILUTE 200 gal PW per hour to compensate for Xenon build-in.
WBN Administration Of The Tl-7.012 1 Reactivity Briefing Sheets And Rev. 0004 Reactivity Control Plans Page 21 of 23 Power Escalation for Simulator Continued Power Increase to 30% RTP:
- 1. DILUTE -2700 gal PW to raise power to -30% and maintain Tave matched with Tref.
- 2. INITIATE ramp up.
- 3. MAINTAIN CBD at 165 steps. Temporary rod withdrawal above 165 steps is allowed to support increases in reactor power provided CBD is re-inserted to approximately 165 steps once the desired power level is achieved and the dilution effects have caught up.
30% RTP Power Maintenance:
- 1. DILUTE -300 gal PW per hour to compensate for Xenon build-in.
- 2. MAINTAIN CBD at 165 steps.
Critical Parameter Limit Required Action Rate of Power Increase As specified in TI-45 Reduce ramp rate or hold power until limits satisfied.

I Appendix D Scenario Outline Form ESD-1 Scenario (Spare) Summary Initial Conditions:
75% power, BOL, 1305 ppm boron. 1 B Main Feedwater Pump tripped 5 days ago, and power has been maintained at 75% while repairs were being completed. 1 B MFP has been restarted and placed in service, minimizing some of the Standby MFP forward flow. The crew is to shutdown Standby MFP per SOl-2&3.01, section 5.11. [41.16]. The crew is then to perform a power escalation using GO-4, Section 5.2 at 2%/hour. 1A MD AFW Pump is out of service for pump bearing replacement. LCC 3.7.5.b was entered 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> ago. 1A MD AFW Pump is expected to be returned to service in 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />.
- 1. Shutdown Standby MFP using SOI-2&3.01 starting at step 5.11. [41.16].
- 2. The crew performs a power escalation using GO-4, Section 5.2 at 2%/hour.
- 3. 1-PT-1-33 Main Steam Header Pressure transmitter fails low. Affects automatic MFP speed control for Feed Reg Valve AP. MFP speed drops, S/G levels lower. BOP takes MANUAL control of the MFP Master Controller and controls speed and Feed Reg Valve AP lAW AOl -16, Loss of Normal Feedwater.
- 4. 1-LT-68-339 fails high, causing charging flow and RCP seal injection flows to drop. RO takes 1-FCV-62-93 to MANUAL and raises charging and RCP seal injection flow. AOl-20, Malfunction of PZR Level Control, is entered. SRO evaluates Tech Specs.
- 5. Containment Pressure transmitter PDT-30-45 fails high. SAC evaluates Tech Specs.
- 6. 1 B MFP trips due to low bearing oil pressure. Since the plant load is not >85%, an automatic runback does not occur, requiring the BOP to perform a manual runback. When the Standby MFP automatically starts, it trips on overcurrent. BOP runs back the turbine to <800 MWe. AOl -16, Loss of Normal Feedwater, is entered.
- 7. During the plant runback and resulting Tave/Tref mismatch, automatic rod control fails. AC takes MANUAL control of rods to reduce reactor power during the runback. Crew enters AOl -2, Malfunction of Reactor Control System.
- 8. SG #2 MSIV fails closed. The resultant pressure transient lifts S/G safety valves. Two safety valves on the same S/G stick open. If the reactor is not tripped manually, a reactor trip occurs due to Cverpower AT. The steam leak requires the operators to actuate a safety injection. The crew performs E-0, and transitions to E-2. When termination criteria are met, the crew performs ES-i .1.
- 9. On the reactor trip, feedwater isolation signal fails. BOP closes valves and stops pumps manually to isolate feedwater.
- 10. BIT Cutlet Isolation Valve i-FCV-63-25 fails to close from the Main Control Room handswitch. RO must implement ES-i .1 Appendix F, Operation of MOVs at Train B Electrical Board.
- 11. The scenario terminates when the crew secures both SI Pumps and places them in automatic lAW ES-1.1.
Critical 1 2 Tasks: Identifies failure of Feedwater Isolation: Isolates faulted S/G prior to transition from E-2:
- Closes MEW isolation valves.
- Isolates AFW flow.
- Closes #1 EW Heater Outlet Valves.
- Closes MEW reg and bypass reg valves.
- Trips MEW pumps.
- Trips demin pumps and cond booster pumps.
