PROGRESS ENERGY FIRE PRA: PUTTING OUR TOOLS TO WORK SE OF LINKED DATABASES IN DEVELOPMENT OF THE PROGRESS ENERGY HNP FIRE PRA

摘要

For the pilot NFPA805 submittal for Harris Nuclear Plant, Progress Energy developed a set of linked database tools to bring together the data necessary to process the Fire PRA. This linked database method is being implemented with development of our subsequent Fire PRAs, providing consistency among the fleet for creation of the Fire PRAs as well as simplifying the process for future PRA updates. The linked database format is based on creating a series of tables, queries, and visual basic coding to link each of the Fire PRA data gathering tasks, Safe Shutdown Analysis, cable routing information, and the Fire PRA model. The linked database method is expected to facilitate many applications, including future updates to the Fire PRA. Updates to data can be as simple as adding new lines to the linked tables and re-running the associated queries. This also simplifies sensitivities, by allowing the data to be treated in aggregate as well as with individual modeling. Progress Energy's utilization of the linked databases allows us to put our tools to work for us.
