Science Applications International Corporation and Florida Power Corporation (FPC) have joined in a tailored-collaboration project on behalf of Electric Power Research Institute (EPRI) to provide shutdown risk management analysis products for EPRI-member utilities. The objectives of the shutdown project are to (1) determine the usefulness of plant safety status information derived from component out-of-service data available from the outage schedule; (2) demonstrate that shutdown safety and reliability models can be efficiently adapted from a probabilistic risk assessment (PRA) model to support shutdown analysis; (3) show that computerized data sources containing shutdown schedule information are available and applicable to the model; (4) demonstrate that software can be created to process the information in a realistic time frame; and (5) use the software tool to assist in the development of the outage schedule and support an actual outage. In addition, the resources required to produce a complete riskbased outage management tool in a subsequent project phase are determined. Use of FPC's investment in the Crystal River-3 PRA can save FPC as much as a million dollars in creating the logic necessary to support a component-level shutdown analysis.
