Appendix D Scenario Outline Form ES-D-1 Events
- 1. The BOP operator will secure from Suppression Pool Cooling using 2-01-74. When Suppression Pool Cooling is secured the scenario may continue.
- 2. The Instrument Mechanic Foreman will call the SRO and report that during performance of 2-SR-3.3.6.1.5(4A/A), Core and Containment Cooling Systems RCIC Turbine Steam Line High Flow Instrument Channel A Calibration, 2-RLY-071-13A-K12 did not energize when 2-PDT-71-1A was pressurized and that they have stopped at step 7.4[7]B. The SRO will evaluate Tech Spec 3.3.6.1 and table 3.3.6.1-1 to determine that function 4a is the affected function and that the Tech Spec requires placing the channel in trip within 24 hours. Once the Tech Spec call is completed the scenario may continue.
- 3. 2-XA-55-4B window 20, RECIRC Pump Motor B Vibration High alarms.
The BOP operator will dispatch an AUO to 2-LPNL-925-0712 and he/she will report that 2-Xl-68-71 D and E are in alarm reading 12.0 mils and rising slowly. The SRO will direct lowering 2B Recirc speed to attempt to clear the alarm. The ATC operator will lower 2B Recirc pump speed. The AUO will report that 2-Xl-68-71 D and E lowered to -10 mils and will reset the alarm locally. When the lead examiner is ready the scenario may continue.
- 4. 2-XA-55-4B window 20, RECIRC Pump Motor B Vibration High alarms again and 2-XA-55-4B, window 25 Recirc Pump B no. 1Seal Leakage ABN, alarms. The number 2 seal pressure will rise to approximately Reactor Pressure. The SRO will direct tripping the 2B Recirc Pump and entering 2-AOl-68-1A. The ATC operator will lower Reactor Power IAW the RCP and 2-AOl-68-1A. The BOP operator will carry out the subsequent actions of the AOI. The SRO will address Tech Spec 3.4.1.
When conditions have stabilized and the lead examiner is ready the scenario may continue.
- 5. The running steam packing exhauster will trip and the standby exhauster will fail to auto start. The BOP operator will place the standby steam packing exhauster in service IAW 2-0l-47C section 6.3 and adjusts its operation to obtain 10-12 inches of H20 vacuum. At that point the scenario may continue.
- 6. The in service 2A CRD Flow Control Valve develops a control air leak causing the valve to slowly drift closed, causing the CRD Charging Header Pressure to go high. The ATC will enter the ARP for High Charging Pressure and attempt to control flow and pressure. The FCV will not respond to any attempt to control and after the AUO is sent to investigate, he reports an air leak, and the ATC uses 01-85 to swap Flow Control
Appendix D Scenario Outline Form ES-D-1 Valves. When the 2B CRD FCV is in service and the lead examiner is ready the scenario may continue.
- 7. A leak in the Drywell will develop causing Drywell Temperature and Pressure to rise. The SRO will set a trigger value for a Reactor Scram and when that value is reached a manual Scram will be inserted or the Reactor will Scram at 2.45 psig Drywell Pressure. All control rods will be inserted on the scram. The SRO will direct entry into 2-AOl-100-1. The SRO will direct Suppression Chamber spray per EOl-2 Appendix 17C.
The BOP operator will attempt to spray the Suppression Chamber however the select logic will fail on both loops of RHR. The SRO/BOP operator will determine that neither the Suppression Chamber nor the Drywell can be sprayed. The SRO may attempt to cool down or anticipate that an ED will be required and attempt to rapidly depressurize the Reactor using the bypass valves however the bypass valves will fail closed. An ED will be required based on Drywell Temperature. As the Reactor depressurizes the action required area of curve 8 RPV Saturation Temp will be entered and Reactor Water Level indication will be lost. The SRO will direct entry into C-4 and the crew will inject using available systems until one of the conditions in C-4, Note 7 is met.
- 8. When the SRO directs a cool down or rapid depression of the RPV using the main turbine bypass valves, the operator will determine and report that the bypass valves have failed closed. This will lead to an ED being required.
- 9. With an accident signal present the Core Spray loop II injection valve will fail to automatically open, the BOP operator will manually open the injection valve.
The Scenario ends when the crew has performed an emergency depressurization and flooded the RPV to the Main Steam Lines.
Appendix D Scenario Outline Form ES-D-1 Critical Tasks: 2
- 1. Emergency Depressurize before 300°F.
- 1. Safety Significance Precludes failure of Primary Containment
- 2. Cues Procedural compliance High Suppression Chamber or Drywell pressure
- 3. Measured by Observation-SRO updates or briefs the crew that ED is required based on not being able to restore and maintain drywell temperature below 280°F AND the operator opens 6 ADS/MSRVs
- 4. Feedback MSRV open indications RPV Pressure lowering
- 2. evel instruments flash, level unknown, inject into the available sources until one of the conditions in C-4, Note 7 is met.
- 1. Safety Significance Prevent fuel damage by establishing adequate core cooling
- 2. Cues Procedural compliance Loss of all RPV level indications
- 3. Measured by Observation-Indications that the Main Steam Lines are flooded are listed in C-4 Note 7
- 4. Feedback MSRV tail pipe temperature MSRV acoustic monitor RPV Pressure trend

Date Title of Evolution: Ur ent Load Reduction/Recirculation Pum Plan Purpose/Overview of Evolution: Maneuver Reactor to maintain acceptable operating conditions during and following unexpected plant conditions. These Urgent Load Reduction steps do not support a . shutdown using the Improved BPWS Control Rod Insertion Process. Maneuver Steps 1 Recirculation Pump Trip:
- 1. IF both pumps trip, SCRAM the reactor per 2-AOl-68-1A.
For a single recirculation pump trip, IMMEDIATELY insert rod groups to lower rod line below 74% using Shove Sheets.
- 2. Change speed of the Operating recirculation pump, as needed, until Core Flow is 46-49% to exit POWER/FLOW region II and Operating Recirculation pump drive flow is below 46,610 gpm.
Urgent Load Reduction: 1A Lower power by lowering core flow until either the desired operating power level is reached or core flow is -60% of rated core flow. (If a recirculation pump trip is imminent, only lower using the pump to be tripped). 2A. Insert control rods per Shove Sheets to lower power until either the desired operating power level is reached or until Load Line is between 55% and 66% .
. 3A. Lower recirculation pump speed to -28% (-480 rpm).
- 4A. Insert control rods per Shove Sheets until desired ower level is reached or SCRAM the reactor.
IUnit2 BFN Reactivity Control Plan Attachment 7 (Page 2 of 5) Reactivity Control Plan Form Reactivity Maneuver Plan #U2 SIMULA TOR Operating Experience ANO General Issues: Operating Experience Perry Nuclear Plant scrammed on OPRM signals -9 minutes after receiving a dual recirculation pump shift to slow speed, before control rods were inserted. CONCLUSIONS/RECOMMENDATIONS: In the event of a Recirculation pump trip or both pumps running back to minimum speed, the control rod insertion should be accomplished as soon as practical due to potential OPRM trip. General Issues This should be considered a guideline, not covering all possible situations. Contact On-Call Reactor Engineer as soon as possible to provide assistance. Note that in the event of a Recirculation Pump trip the Load Line may go over 113.6% and MFLCPR may exceed 1.0 but the insertion of the recommended control rod groups will return Load Line and MFLCPR below the required limits. If a Powerplex case runs in the transient condition, the case is considered invalid. An automatic case may be triggered in the event of a recirculation pump trip and that case should be considered invalid and another case requested as soon as reactor power stabilizes. ff shutdown is required while operating in single roop with the OOS loop isolated, Scram unit prior to going to minimum flow on operating recirculation pump to avoid flow stratification concerns. Recommend scramming between 40 to 45% RTP. Cautions/Error Likely Situations/Special Monitoring Requirements/Contingencies: During SLO, reactor power and flow conditions will be near to Region 2. Operation in SLO requires the following conditions to be met:
- Reactor power ,:::50% of rated power
- Core Flow _:::50% of rated core flow
- Operating pump drive flow .::;46.610 GPM Operating pump speed ,:::100% of rated speed
- POWERPLEX using a SLO thermal limit set
- MFLCPR <0.94 The RE must be contacted to change the PowerPlex calculation using the correct Thermal Limit set while in SLO. Th RE must also change the Thermal Limit set if the plant is operating with reduced feedwater heating.
In the event of change in Feedwater heating, then evaluate Final FW Temperature versus Core Thermal Power graph to determine if change required to Fuel Thermal Limits. Graph may be found on ICS as FWTCTP. in Appendix S of O-Tl-248 or in this Attachment. In the event of change in steam path to turbine (such as a MSIV or turbine valve malfunction). then evaluate Dome Pressure versus Fraction Rate Thermal Power to determine if operation is within limits. Graph may be found on ICS as RXPCTP, in Appendix S of O-Tl-248 or in this Attachment.

Appendix D Scenario Outline Form ES-D-1 Events
- 1. BOP secures Drywell Purge in accordance with 2-01-64 Section 8.1. After the OW and Torus Purge has been secured, the scenario may continue.
- 2. ATC will withdraw control rods in order to raise power to 8% for a mode change from 2 to 1. Once the Chief Examiner has seen an appropriate amount of power rise he may choose to continue with the next event which will halt control rod withdrawal.
- 3. Control Rod 02-39 will begin to drift in to approximately position 10, and the ATC will respond IAW 2-AOl-85-5 and bypass the RWM and insert Control Rod 02-39 to position 00. The SRO will declare Control Rod 02-39 inoperable and refer to Tech Spec 3.1.3 condition C. The SRO will also refer to Tech Spec 3.1.6 condition A for BPWS and 3.3.2.1 condition C for RWM. Once the rod has been inserted and the Tech Spec call has been made the scenario may continue.
- 4. Loss of SJAE A, BOP operator swaps to B SJAE IAW 2-AOl-47-3, Loss of Condenser Vacuum or IAW 2-01-66 or the hardcard. After the standby SJAE has been placed in service and Main Condenser vacuum has recovered, the scenario may continue.
- 5. The ATC will respond to a failure of IRM 'B' upscale and notice and report that a% scram failed to come in on the upscale condition. The crew will be unable to bypass IRM 'B' since IRM 'D' is currently bypassed. The SRO will refer to Tech Spec 3.3.1.1 and enter condition 'A'. The required action is to place a channel in trip in 12 hours. After the SRO has completed the Tech Spec call the scenario may continue.
- 6. D 4KV Shutdown Board will lose power and the D Diesel Generator will fail to automatically tie to the Shutdown Board. The BOP will manually tie the Diesel to the board. SRO will refer to Tech Specs and determine TS 3.8.1 condition A, B, and G, and TS 3.8.7.A. The ATC will be resetting RPS and PCIS. After the BOP Operator ties the Diesel to the Buss and the SRO has completed the Tech Spec call the scenario may continue.
- 7. The ATC will respond to a trip of the 2C RFP IAW 2-AOl-3-1 by raising the speed of the warm RFP 2B to feed the RPV. Once the ATC has entered AOl-3-1 and raised the speed on the standby Reactor Feedpump to maintain RPV Water Level the scenario may continue.
- 8. At the cue of the Chief Examiner initiate the next event. An unisolable leak will develop on the suppression chamber. The US will direct entry into EOl-3 on secondary containment area flood alarms and EOl-2 on suppression pool water
Appendix D Scenario Outline Form ES-D-1 level. Prior to 12. 75 ft, in the Suppression Pool, the US will direct HPCI to be secured and locked out. Prior to 11.5 ft in the Suppression Pool the US will transition to EOl-1 and direct a SCRAM. An ATWS will exist on the SCRAM. The crew will work through EOl-1 and C-5 to insert control rods, maintain reactor water level, and reactor pressure. The US will transition to C-2 to emergency depressurize before Suppression Pool water level lowers to 11.5 feet.
- 9. The US will direct terminating and preventing IAW EOI Appendix 4, and the 2B RFP governor will fail as is. The ATC/BOP will Trip the 2B RFP.
- 10. The BOP will report that two of the ADS SRV's failed for Emergency Depressurization. Two additional non ADS SRV's will be opened at the direction of the SRO.
The Scenario ends when Emergency Depressurization and Reactor Water Level is restored and maintained within the assigned band or upon request of Lead Examiner.
Appendix D Scenario Outline Form ES-D-1 Critical Tasks 3
- 1. When Suppression Pool Level cannot be maintained above 12.75 feet HPCI secured to prevent damage.
- 1. Safety Significance:
Prevent failure of Primary Containment from pressurization of the Suppression Chamber
- 2. Cues:
Procedural compliance Suppression Pool Level indication
- 3. Measured by:
Observation - HPCI Auxiliary Pump placed in Pull to Lock
- 4. Feedback:
HPCI does not Auto initiate No RPM indication on HPCI
- 2. When Suppression Pool level cannot be maintained above 11.5 feet the US determines that Emergency Depressurization is required, RO initiates Emergency Depressurization as directed by US.
- 1. Safety Significance:
Precludes failure of Containment
- 2. Cues:
Procedural compliance Suppression Pool Level Trend
- 3. Measured by:
Observation - US determines (indicated by announcement or observable transition to C-2) that Emergency Depressurization is required before Suppression Pool level drops below 11.5 feet. Observation - RO opens at least 6 SRV's during performance of Emergency Depressurization actions.
Appendix D. Scenario Outline Form ES-D-1
- 4. Feedback:
RPV pressure trend SRV status indications Suppression Pool temperature trend
- 3. With RPV pressure <MSCP, slowly increase and control injection into RPV to restore and maintain RPV level above TAF as directed by US.
- 1. Safety Significance:
Maintaining adequate core cooling and preclude possibility of large power excursions.
- 2. Cues:
Procedural compliance RPV pressure indication
- 3. Measured by:
Observation - Injection not commenced until less than MSCP, and injection controlled such that power spikes are minimized, level restored and maintained greater than TAF

When power has been restored to the RMOV boards, the crew will respond to a trip of RBCCW Pump 3B IAW 3-AOl-70-1, and notice the RBCCW sectionalizing valve failing to auto close and manually closing the sectionalizing valve. When the Tech Spec calls are completed and the lead examiner is ready the scenario may continue.
- 4. Condenser Vacuum will begin to degrade causing the Crew to enter 3-AOl-47-3 and direct reducing reactor power in an attempt to maintain condenser vacuum. Condenser Vacuum will continue to degrade. The SRO will set a trigger value to trip the main turbine and scram the reactor before an automatic turbine trip occurs at approximately 24.3 inched Hg.
- 5. If the Crew attempts to place RCIC in service, it will trip on low suction pressure. It will remain unavailable from that point forward.
- 6. After the Reactor Scram on vacuum, a Loss of Offsite Power will occur. The crew will respond to the Reactor Scram IAW 3-AOl-100-1 and O-AOl-57-1A.
- 7. During the LOOP DG 3EA will fail to automatically start and will have to be manually started and after it starts auto tie to the buss.
- 6. Sometime after the LOOP a LOCA will develop requiring the crew to use systems to maintain Reactor Level and Containment parameters.
- 7. The HPCI Steam Supply Valve, 3-FCV-73-16, will fail to OPEN on an automatic HPCI initiation signal, but can be initiated manually.
The scenario ends when Drywell Sprays have been initiated and Reactor Level is maintained above TAF ((-)162 inches) or upon request of Lead Examiner.

4.2 Subsequent Actions NOTES
- 1) SBO Unit does attachment 12 only; the other two units perform subsequent actions of AOI.
- 2) If a Unit is in a Station Blackout condition, performance of this instruction will also require implementation of 1(2)(3)-AOl-30B-BOP 1, Reactor Building Ventilation Failure, on the Unit in Station Blackout.
- 3) The following is the preferred pump combinations of Unit 1 and Unit 3 RHR pumps used in SOC: 1B/20, 1A/3C, 1A/2D, 1B/3C.
By using these pumps it ensures that a loss of a Diesel during a station blackout would not result in a loss of Shutdown cooling for both Unit 1 and Unit 3. Page 42of68 Unit 3

Maneuver Steps Recirc Pump Trip:
- 1. IF both pumps trip, SCRAM the reactor per 3-AOl-68-1A For a single recirculation pump trip, IMMEDIATELY insert rod groups to lower rod line below 95%.
- 2. Change core flow with the Operating recirculation pump to exit POWER/FLOW region 2 and prevent loop delta temperature concerns (>45%).
Urgent Load Reduction: 1A. Lower power by reducing core flow until either the desired operating power level is reached or core flow is 74% to 75% of rated core flow. (If a recirculation pump trip is imminent, only lower using the pump to be tripped). 2A. Insert control rods by groups per Emergency Shove Sheet to obtain the desired power level.
BFN Reactivity Control Plan Page 3of15 Unit 3 Attachment 7 (Page 2 of 4) Reactivity Control Plan Form Reactivity Maneuver Plan #: U3 NRC Exam Maneuver Steps (continued) Urgent Load Reduction (continued): 3A. Lower core flow to 46% core flow. (If a recirculation pump trip is imminent, only lower using the pump to be tripped.) 4A. Insert control rods Emergency Shove Sheet until load line is between 55% and 66.7%. SA. Reduce recirculation pump speed to -28% (-480 rpm). SA. SCRAM the reactor or continue control rod insertion until SCRAM.
BFN Reactivity Control Plan Page 4of15 Unit 3 Attachment 7 (Page 3 of 4) Reactivity Control Plan Form Reactivi Maneuver Plan #: U3 NRC Exam Operating Experience AND General Issues: Operating Experience Perry Nuclear Plant scrammed on OPRM signals -9 minutes after receiving a dual recirc pump shift to slow speed, before control rods were inserted. CONCLUSIONS/RECOMMENDATIONS: In the event of a Recirc pump trip or both pumps running back to minimum speed, the control rod insertion should be accomplished as soon as practical due to potential OPRM trip. General Issues This should be considered a guideline, not covering all possible situations. Contact On-Call Reactor Engineer as soon as possible to provide assistance. Note that in the event of a Recirc Pump trip the loadline may go over 113.6% and MFLCPR may exceed 1.0 but the insertion of the recommended control rod groups will return loadline and MFLCPR below the required limits. If a Powerplex case runs in the transient condition, the case is considered invalid. An automatic case may be triggered in the event of a recirc pump trip and that case should be considered invalid and another case requested as soon as reactor power stabilizes. If shutdown is required while operating in single loop with the OOS loop isolated, Scram unit prior to going to minimum flow on operating recirc pump to avoid flow stratification concerns. Recommend scram min between 40 to 45% RTP.
BFN Reactivity Control Plan Page 5of15 Unit 3 Attachment 7 (Page 4 of 4) Reactivity Control Plan Form Reactivity Maneuver Plan#: U3 NRC Exam Cautions/Error Likely Situations/Special Monitoring Requirements/Contingencies: During SLO, reactor power and flow conditions will be near to Region 2. RE must calculate and substitute core flow value when reducing flow in the active jet pump loop below 41 Mlbm/hr per 3-SR-3.4.1 (SLO). Prerequisites for starting an idle Recirc Pump, (3-01-68):
- Operating recirc pump flow is below 46,600 gpm.
- Operating recirc pump speed is less than 860 RPM speed.
- Reactor operating conditions are outside of Region 1,2 and 3.
- 10% margin between reactor power and APRM rod block setpoint.
The RE must be contacted to change the PowerPlex calculation using the correct Thermal Limit set while in SLO. (#15 SLO NSS BOC to NEOC RPTOOS). The RE must also change the Thermal Limit set if the plant is operating with reduced feedwater heating. (#16 - TLO NSS ICF BOC to NEOC RPTOOS, FHOOS)
