Course Overview

The U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research (RES), will sponsor a fire module workshop on fire probabilistic risk assessment (PRA). Working under a Memorandum of Understanding (MOU) for Cooperative Nuclear Safety Research, RES and Electric Power Research Institute (EPRI) have been developing state-of-the-art methods for conducting fire PRAs. In September 2005, the collaboration produced "EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities" (NUREG/CR-6850/EPRI 1011989), which is the subject of this 2019 course. Training will also include discussions relating to the fire PRA portion of the ASME/ANS PRA Standard.

Module I: PRA

This module covers the technical tasks for development of both the system and operator response to a fire. Specifically, this module covers NUREG/CR-6850, EPRI 1011989 Volume 2, Tasks:

• Component Selection (Task 2)
• Qualitative Screening (Task 4)
• Fire-Induced Risk Model (Task 5)
• Quantitative Screening (Task 7)
• Fire Risk Quantification (Task 14)
• Uncertainty and Sensitivity Analysis (Task 15)

This module is suited for PRA practitioners responsible for the systems modeling aspects of the fire PRA. Specifically, participants in this module should possess the following knowledge:

• A general knowledge of PRA as applied to nuclear power plants, including typical approaches, modeling techniques (event trees, fault trees, interfaces between PRA and HRA), and the quantification of PRA models.
• Some familiarity with plant systems typically found in nuclear power plants. A simplified, but reasonably realistic example of a few plant systems will be used to demonstrate the methodology.
• Some familiarity with P&IDs and their use in developing PRAs
