APPLICATION OF FRANX SOFTWARE TO EXTERNAL EVENTS

摘要

The EPRI FRANX software has been used for several years as a tool to assist the Probabilistic Risk Assessment (PRA) analyst in incorporating fire related impacts and modeling attributes into existing PRA models. This simplifies the process of performing a Fire PRA and the ultimate incorporation of the fire model into a configuration risk model. Recent developments in FRANX have increased the capabilities to model numerous other spatially-dependent and scenario-dependent situations. More recent applications of the tool have included the modeling of flooding scenarios, thereby including these scenarios into the PRA model in a structured and automated manner, avoiding laborious hand development of models. Of particular note are improvements in the tool to support seismic analysis in a highly structured manner. These seismic add-ons allow for the simple development of seismic scenarios from the hazard curve, automatic implementation of the appropriate fragility information, and integration with the full Level 1 PRA model. This paper discusses the expanded capabilities of the FRANX software tool, with particular emphasis on external event coverage such as flooding and seismic capabilities.
