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.

The PRA Applications Wiki is 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, and rationale for each application. 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.

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.

With the issuance of Regulatory Guide 1.200, Revision 3 the US Nuclear Regulatory Commission (NRC) endorsed the concept of a “Newly Developed Method (NDM)” for use in Probabilistic Risk Assessments (PRAs). This Wiki shares information from previous evaluations within the industry specifically that have been provided to EPRI for inclusion in the Wiki. These evaluations of interest are those related to whether a PRA method is considered an NDM, and whether an NDM Peer review has been conducted to determine the technical adequacy of the method for inclusion in risk applications as necessary.

The EPRI software is designed to be very flexible to support a variety of research in the creating and applying PRA models. In many cases, this diverse set of features can be confusing or can lead to creation of models that cause problems in subsequent applications. Although there is rarely a "best way" to create a PRA model, some techniques will make the software more efficient or enable certain features.
