SUMMARY

Length : 90 minutes Initial Power Level: 4% with plant shutdown in progress Mitigating Strategy Code: RR4, fuel leak with a failure of EC tubes and EC fails to isolate, requires RPV Blowdown to stop release The crew assumes the shift with the plant being shutdown.

The crew is directed to de-inert the containment in accordance with N1-OP-9, FJ2 lnerting and H2-02 Monitoring Systems. When drywell pressure is lowered to 0 psig, the operator will secure the lineup, but one of the containment isolation valves will fail to fully close. This will require entry into Technical Specifications and ensuring a second valve in the line is isolated.

Then the crew will continue the shutdown by inserting control rods. Next Reactor Building Radiation Monitor 12 will fail upscale causing a trip of RBVS and a start of RBEVS. Additionally there will be a failure of the Reactor Building to isolate.

The crew must isolate the Reactor Building to restore Secondary Containment and the SRO must address Technical Specifications. When these acticins are complete, both seals on the 1 I Recirculation Pump will fail requiring the crew to shutdown and isolate the pump. Following the loss of the Recirculation Pump, a fuel failure will cause offgas and main steam line radiation levels to rise, requiring a reactor scram and vessel isolation.

Multiple control rods will fail to fully insert during the scram requiring the crew to enter N1-SOP-1 and take alternate actions to insert the control rods. The rods are inserted using RMCS. NRC Scenario 1 1 October 2008 Following the scram, the crew will diagnose an Emergency Condenser tube leak. They will try to isolate the affected EC but the isolation valves will fail to fully close. Rising off site radiation levels will require an RPV blowdown before General Emergency levels are reached.

SUMMARY

Length : 90 minutes Initial Power Level: 90%, 4 Loop Operation Mitigating Strategy Code: SCI, unisolable primary system leak in the Secondary Containment, RPV Blowdown required The crew assumes the shift with the plant operating at 90% power and four recirculation loops in service.

Immediately after assuming the shift the crew will be directed to restore Recirculation Pump 15 to service and return to full power. The crew will assess plant conditions and lower power with Recirculation Flow until flow is less than 50 Mlbm/hr. They will then return Recirculation Pump 15 to service. After the crew has placed the pump in service, the Main Generator Auto Voltage Regulator will fail. The crew will diagnose the failure and take manual control of generator voltage and restore the correct generator output. When a normal generator output is established, the Control Rod Drive Flow Control Valve fails closed, requiring shifting to the alternate FCV. After CRD flow is returned to normal, a loss of power to Power Board 11 occurs. The SRO will address Technical Specifications.

A Reactor Water Cleanup system line break will occur in the Secondary Containment downstream of the Supply Isolation Valves. Reactor Water Cleanup will fail to isolate on high area temperature. The crew will attempt to isolate the system, but the valves will fail to fully close. This break will require a scram and RPV blowdown due to exceeding the Maximum Safe Value for general area temperatures. When the Mode Switch is placed in SHUTDOWN and/or the Reactor Trip pushbuttons on the E Panel are pushed, the reactor will NOT scram. ARI must be manually initiated to scram the control rods.

SUMMARY

Length: 90 minutes Initial Power Level: Approximately 1 OO%, above 100%

rodline Mitigating Strategy Code: RL2, Small LOCA, RPV Blowdown required to permit injection with low presisure systems to recover RPV water level above TAF

SUMMARY

The crew assumes the shift with the plant at 100% power with Feedwater Pump 12 under clearance for maintenance. The crew will perform N1 -PM-Q7, Turbine Thrust Bearing Test from the Control Room. Next, APRM 13 fails. The crew will bypass the APRM and reset the half scram. Next, Powerboard 103 trips on fault. The crew will take action to secure EDG 103 and attempt to restore Powerboard 17B. F'owerboard 103 and Powerboard 17B are both faulted and are not restored.

The trip of CliD Pump 12 (PB 17B) will require starting CRD Pump 11 and the SRO must address Technical Specifications. When the necessary steps for the loss of Powerboard 103 are completed, Feedwater Booster Pump 11 will trip with a failure of the standby pump to start. The standby pump can be manually started. The SRO must again address Technical Specifications.

When the standby Feedwater Booster Pump is manually started, the Master Feedwater Controller will fail as-is. RPV water level will slowly deviate from the set level. The crew must diagnose the failure and the BOP operator will be required to take nianual control of RPV water level. With RPV water level in manual control, Feedwater Pump 11 will trip because of delayed effects from the earlier NRC Scenario 3 1 October 2008 Feedwater Booster Pump trip. This will require an entry into N1-SOP-1 .I, Emergency Power Reduction to lower power to within the capacity of Feedwater Pump

13. While troubleshooting the electrical faults and troubles with the Feedwater system, the crew recognizes a coolant leak in the containment. Drywell pressure and temperature rise, requiring the crew to insert a manual SCRAM on rising drywell pressure.

When the turbine trips, Powerboards 11 and 12 fail to automatically transfer. This results in a loss of feedwater, condensate, circulating water and other loads. Operators are able to restore these power boards. RPV water level continues to drop with only one liquid poison pump and CRD pump 11 available for injection.

The crew will determine they cannot restore and maintain RPV water level above -1 09" and enter N1 -EOP-8, RPV Blowdown.

While blowing down the crew must diagnose that the inboard IV for Core Spray 11 1 fails to open and Core Spray pump 121 fails to start. With Core Spray unavailable for injection, the crew will inject with the feedwater booster pumps using N1-EOP-1, Att 25 or 26.

Next, the crew will be directed to return TBCLC Pump 12 to service and secure TBCLC Pump 11. When this is complete, an RPS pressure transmitter will fail low, followed closely by the in-service feedwater system pressure transmitter also failing low. The crew will be required to shift to manual feedwater level control. The crew may then shift reactor pressure/level columns and return to automatic feedwater level control. Technical Specifications must be addressed due to the RPS pressure transmitter failure. Next the crew must respond to high D/P across one of the Service Water Pump Discharge Strainers.

This will require placing another Service Water Pump in service. Once the standby Service Water Pump has been started, Main Steam Line Radiation Monitor 11 1 will become inoperable.

The SRO will determine the Technical Specification implications. Next the intake structure traveling screens clog causing higii D/Ps. This will eventually result in a low level in the intake structure with the subsequent tripping of the Circulating Water pumps. This will require entering N1-SOP-18.1, Service Water Failure/Low Intake Level. As intake level continues to lower, the crew will insert a manual scram.

When the scram occurs the control rods will not insert.

This ATWS is complicated by the total NRC Scenario 4 - October 2008 loss of the normal heat sinks. Additionally, following the ATWS, a Recirculation Line break will cause RPV water level to lower, requiring the crew to re-establish injection.

When the crew attempts to re-establish Feedwater flow, the Feedwater isolation valves will not re-open.

When it is determined that RPV water level cannot be restored and maintained above -1 09 inches, the crew will perform an RPV Blowdown, and re-inject with Core Spray. Major Procedures:
