Catawba Nuclear Station NRC Exam December 2010 Scenario I - Summary Initial Condition Unit I is at 50% power BOL. IA LH pump is tagged out.

Turnover:

1A LH pump is tagged out to repair a leak on the motor cooler. Maintenance estimates that repairs will take 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />. Direction for the crew is to increase reactor power to 100%.

Event 1 BOP will perform an NC system dilution and RO will set turbine control setpoints to begin power increase to 100% power.

Event 2 An HVAC panel alarm will require the BOP to step out of the horseshoe area. Subsequently pressurizer PORV I NC-34A will fail open. RO will attempt to manually close the PORV unsuccessfully, and will have to close the PORV isolation valve per the immediate actions of AP/1/N5500/01 I (Pressurizer Pressure Anomalies) Case 1. Crew enters AP/1 1 to address this issue. TS evaluation by SRO is required.

Event 3 KC surge tank B level switch that feeds automatic isolation of both non essential headers fails low. With an A train KC pump running, this causes a loss of cooling flow to the running 1 B NV pump. Crew will enter AP/1/A15500/021 (Loss of Component Cooling Water) to address this issue. The first B train KC pump that the crew tries to start fails. The second pump starts. TS evaluation by SRO is required.

Event 4 A 15 GPM tube leak develops on the 1D SIG. Crew will enter AP/1/A/5500/010 (Reactor Coolant Leak) Case I to address. TS evaluation by SRO is required. A shutdown will be required due to the leak size. AP/1/A!5500/009 (Rapid Downpower) will be entered to direct the shutdown.

Event 5 When a TavglTref mismatch of> 1.5 degrees F exists, RO will recognize that control rods failed to insert as required. Crew will enter AP/1/N5500/01 5 (Rod Control Malfunction).

Event 6 Tube leak size on 1 D SIG increases to the point that the crew will not be able to maintain pressurizer level. AP/1/A15500/01 0 End. 1 guidance states for the crew to manually trip the reactor and safety inject and to go to E-0 (Reactor Trip or Safety Injection).

Event 7 SIG ID PORV fails open, providing a release path to the environment. RO will attempt to manually close the PORV and eventually close the PORV isolation valve Event 8 Automatic actuation of Phase A containment isolation fails, requiring BOP to manually initiate or to ensure that at least one valve in each major penetration from containment is closed.

Critical task I Close containment isolation valves such that at least one valve is closed on each critical phase-A penetration before the end of the scenario.

Critical task 2 Depressurize the RCS to meet SI termination criteria before SIG ID reaches 92% narrow range leveL Appendix D Catawba NRC Exam Dec 2010 NUREG 1021 Revision 9 Page 3of38

Catawba Nuclear Station NRC Exam December 2010 Scenario 2 Summary Initial Condition Unit 1 is just below POAH during startup. 1A LH pump is tagged out.

Turnover:

IA LH pump is tagged out to repair a leak on the motor cooler. Maintenance estimates that repairs will take 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> to complete. Direction for the crew is to increase reactor power to 10%.

Event 1 BOP performs an NC system dilution to offset Xenon buildup. RO withdraws control rods to establish a positive startup rate to increase reactor power.

Event 2 2A RN pump trips. Crew will enter AP/0/A/5500/020 (Loss of Nuclear Service Water) to address this issue. TS evaluation by SRO is required.

Event 3 Intermediate range nuclear instrument N-36 experiences a high voltage failure. Crew will enter API1IA/55001016 (Malfunction of Nuclear Instrumentation System) Case 3 to remove this channel from service. TS evaluation by SRO is required.

Event 4 2 of 3 W/R SIG level channels on 1 C SIG begin to slowly fail to 40% level. This will cause the feedwater regulating bypass valve to slowly open up to maintain SIG level. This will cause an increase in actual level, and will require the RO to take manual control of the bypass valve to decrease SIG level back to program level. Crew will enter AP111A155001006 (Loss of SIG Feedwater) to address this issue.

Event 5 Reactor coolant pump 1A vibration begins to increase to 30 mils on the shaft. This is above the trip criteria for the pump and will require the crew to trip the reactor and trip the reactor coolant pump.

Event 6 As soon as the IA reactor coolant pump is secured a large break LOCA occurs on A loop. Crew will enter E-0 (Reactor Trip or Safety Injection), make a transition to E-i (Loss of Reactor or Secondary Coolant), and when FWST level decreases to 37% will transition to ES-1.3 (Transfer to Cold Leg Recirculation).

Event 7 Automatic Main Steam Isolation trains A and B fails to actuate on containment pressure> 3 psig. This will require manual initiation by the RO.

Event 8 At 45% FWST level, 1A ND pump will trip. When FWST level decreases to 37% (transfer to cold leg recirc setpoint), 1 B ND pump trips. This will require the crew to transition from ES-i .3 to ECA-i.i (Loss of Emergency Coolant Recirc) to address this issue.

Critical task I Trip all reactor coolant pumps on a loss of subcooling per E-O EncL I guidance within 5 minutes of criteria being met.

Critical task 2 Makeup to the FWST and minimIze FWST outflow.

Event 3 Power range N-42 control power fuse blows. Crew will enter AP/1/N5500/016 (Malfunction of Nuclear Instrumentation) Case 4 will be entered to remove this channel from service. TS evaluation by SRO is required..

Event 4 IA CFPT trips. An automatic turbine runback to 65% does not occur and requires RO to manually decrease turbine load. AP/1/A15500/003 (Load Rejection) will be entered Event 5 I B CFPT trips, causing a loss of all feed flow to the SIGs. Immediate actions of AP/1/N5500/006 (Loss of S/G Feedwater) will have the RO trip the reactor with reactor power greater than 5%.

Event 6 Upon reactor trip, the turbine will fail to trip automatically and manually, requiring the RO to manually close the turbine control valves. Crew enters E-0 (Reactor Trip or Safety Injection).

Event 7 IA and I B motor driven CA pumps fail to start automatically and cannot be started manually. CAPT

  1. I will trip on a mechanical overspeed.

Event 8 Once all SIG levels decrease to less than 11% NR level, a transition will be made to FR-H.1 (Response to Loss of Secondary Heat Sink). Crew will establish feed flow to at least one SIG from the main condensate system by depressurizing a SIG to less than 505 psig and aligning CF flow to the CA nozzles on the SIG to be fed.

Critical task I Manually trip the main turbine before a severe (orange-path) challenge develops to either the subcriticallty or the integrity CSF or before transition to ECA-2. I (Uncontrolled Depressurization of All S/Gs), whichever happens first.

Critical task 2 Establish feedwater flow to at least one SIG before reactor coolant system feed and bleed is required.
