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.
Access: Public
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.
PRA Newly Developed Methods Wiki
Access: Public
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.
Access: Public
The seismic probabilistic risk assessment (SPRA) Wiki summarizes a structured framework for the conduct of an SPRA analysis. This wiki is intended to serve the needs of a seismic risk analysis team by describing a structured framework for conduct of the overall analysis, as well as providing references to specific recommended practices to address each key aspect of the analysis. The wiki provides overall guidance, with an emphasis on seismic hazard analysis, SPRA systems analysis, equipment list development, fragility guidance, human reliability analysis, and model development and quantification.
NMAC

EPRI 3D applications demonstrate the disassembly, reassembly, inspection and operation of specific power plant components. The applications consist of single mode or dual mode meaning they can be executed as a desktop application on a desktop/laptop computer and/or as a virtual reality (VR) application using a VR head-mounted display (HMD), such as the HTC VIVE.

The Valve wiki provides basic entry level information related to common valve and actuators found in the nuclear industry. Descriptions are provided within as well as basic design and maintenance related information. EPRI technical reports are referenced within and include live links for quick access downloads.
Access: Member Only
Terry turbines used in the Reactor Core Isolation Cooling (RCIC) and Auxiliary Feedwater (AFW) systems are covered in this wiki. Basic system level information and Turbine specific information is discussed. EPRI reports are referenced and live linked when appropriate.
Access: Member Only
Electronic work packages (eWPs) have become a primary innovation vehicle for integrating work activities with basic plant workflow process and information systems currently used in the work management process. The EPRI NMAC recognizes the potential benefits that eWPs can provide and has promoted industry collaboration to drive this initiative since 2013. This Wiki site was created to assist utilities with technical content needed to drive eWP success at the site.
Access: Member Only
The purpose of this wiki is to gather all the FLEX related documents into one easily accessible location for members who have interest/responsibility in/for FLEX equipment . This wiki is the storage location for past Instant Benchmarking Requests (IBRs), industry best practice documents and anything else generated by the FLEX Industry Working Groups.
Access: Member Only
The CBM Wiki is a comprehensive page for all Condition Based Maintenance (CBM) technologies with focus on Acoustics, Infrared, Lubrication, and Vibration technologies. CBM stories such as Lube Notes, Vibe Notes and others provide an excellent source of case histories and technical reference for solving practical plant/industry issues. Links to active EPRI reports are included as well as past meeting proceedings and materials.
PE/Programs
EPRI Procurement Information Center (EPIC)
Access: Member Only
EPIC contains technical information related to nuclear procurement and supply chain, research focus areas within the Nuclear Plant Engineering Program at EPRI. It’s organized by major activities in the procurement process. The activity-specific pages provide brief descriptions of each activity as well as links to EPRI guidance and training that is available for performing the activity, industry surveys relating to the activity, and related presentations that have been given at past JUTG meetings.
Access: Member Only
The PEER Cable Aging Wiki covers selected content from Instrument Cable, Low Voltage Power & Control Cable, and Medium Voltage Insulations Cable Polymer Handbooks, including Industry Background and History, Basic Cable Structure, Materials Used, Installation Process, Degradation Mechanisms, and Walkdown Inspections.
Access: Member Only
This Wiki provides a consolidated source of information related to the topic of selective leaching degradation. Summarized information associated with this degradation mechanism, as well as NDE techniques, are included within. References and links are also provided to relevant EPRI research reports, as well as past EPRI meeting materials associated with the topic.
Access: Member Only
The Condenser Wiki Site contains content from the Comprehensive Condenser Resource, Main Condenser Integrity Assessment Guide, and Condenser Application and Maintenance Guide, along with material from pertinent heat exchanger references. The material is organized by topic and enable users with a single, searchable, and easily accessible site dedicated to the topics of the main condenser. Because the Condenser Wiki is updated when new research or experience is available, the site should be beneficial for indoctrination of newer engineers and scientists as well as a resource for experienced professionals.
Plant Reliability and Resilience
Maintenance Rule User's Group (MRUG)
Access: Member Only
The purpose of this wiki is to gather all the MRUG meeting materials and member surveys into one easily accessible location for members. This wiki page will store past member benchmarking surveys and meeting material generated for the semi-annual MRUG meetings. Documents and other materials produced by the MRUG will be summarized within this Wiki and links will be provided from this page. This page is also intended to complement EPRI's Maintenance Rule User's Group Page and Collaboration pages.
Equipment Reliability Working Group (ERWG)
Access: Member Only
The purpose of this wiki is to gather all the Equipment Reliability Working Group (ERWG) meeting materials and member surveys into one easily accessible location for members. This wiki page will store past member benchmarking surveys and meeting material generated for the semi-annual ERWG meetings.
Single Point Vulnerability (SPV)
Access: Member Only
Unplanned reactor scrams present generational losses as well as challenges to safety systems and operations staff. This wiki is based on EPRI Report 3002029784, Single-Point Vulnerability Process Guide, Revision 2 and provides the detailed steps needed to develop and implement an SPV program. A comprehensive program, as described herein, will ensure that SPVs are identified and dispositioned appropriately to reduce the likelihood of an unplanned reactor scram. This wiki includes identification of active, passive, and conditional SPVs. Also included is a best-practice approach called SPV hardening. SPV hardening should be implemented when elimination is not an option. This wiki includes industry best practices, different approaches, and specific organizational responsibilities. Best-performing organizations have demonstrated heavy bias for SPV elimination (when feasible) and risk elimination. These types of organizational behavior should be modeled for improving equipment reliability throughout the industry.
