Welcome to the central link to the wiki pages available from EPRI's Nuclear Engineering and Plant Performance Department.
EPRI's Nuclear Engineering and Plant Performance Department is comprised of three research programs:
- Plant Reliability and Resilience (PRR) Program - provides research supporting reliable and resilient operations of components, systems, and the nuclear plant, as a whole. This work covers mechanical, electrical, and I&C and addresses maintenance, engineering, and programmatic guidance and best practices.
- Risk and Safety Management (RSM) Program - provides research addressing Probabilistic Risk Analysis (PRA/PSA), External Hazards, and Thermal-Hydraulic applications for nuclear plants.
- Operating Plant Initiatives (OPI) - includes major project initiatives that the plant may undertake during plant life such as Plant Modernization, Longterm Operations (LTO), and Power Uprates (PUR).
Links to individual wikis developed by each of these programs are provides below. The search function above can be used to search across all of these wikis.
Plant Reliability and Resilience (PRR)
The reliability and resilience of plant systems and components is critical to the safe and effective operation of all nuclear plants. The Plant Reliability and Resilience (PRR) Program encompasses a diverse set of research activities related to the mechanical, electrical, and instrumentation and control components and systems in use at nuclear power plants, along with the maintenance and engineering processes and programs that manage this equipment. As of 2024, EPRI’s Plant Reliability and Resilience Program includes all the research formally delivered by EPRI’s Nuclear Maintenance Application Center (NMAC), Plant Engineering (PE) Program, and Instrumentation and Control (I&C) Program and can be categorized into:
- PRR - Nuclear Maintenance / Active Components
- PRR - Balance of Plant (BOP) / Passive Components
- PRR - Electrical
- PRR - Instrumentation and Control (I&C)
- PRR - Equipment Reliability (ER) and Related Processes
- PRR - Procurement Processes
