PRA Information
EPRI's Risk and Safety Management Program provides on-going research in methods and tools for conducting probabilistic risk assessments (PRAs). Working with experts around the globe, methods are improved by evaluating data and industry experience, developing applied research in numerical and logic modeling techniques, and developing new ways to apply PRAs in a risk-informed framework.
Basic information on PRAs as applied throughout the industry is available in the links below.
(These links are currently only available to EPRI members or members of the EPRI Risk and Safety Management (RSM) program).
The PRA Applications Wiki provides an introduction to the wide applications of PRA in the nuclear industry. This serves the needs of the global PRA community, providing a clear description, purpose, rationale of the applications. Both voluntary and regulatory PRA applications are described and this overview distinguishes those that require license-basis changes. References to more technical information provide a resource to expand your knowledge further.
The Fire PRA Wiki summarizes a structured framework for the conduct of a Fire PRA analysis. This supports your fire risk analysis team by providing an introduction to EPRI 1011989 / NUREG/CR-6850, updated with the latest information. The methodology addresses a Fire PRA that focuses on a Level 1 PRA (Core Damage Frequency) with consideration of Large Early Release Frequency. Additional references to specific recommended practices are provided, which address each key aspect of the analysis.
