Module IV – Human Reliability Analysis

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 IV: HRA

This module covers technical tasks related to modeling human failure events (i.e., the failure of operator responses) in a fire context. This module will focus on the guidance provided in draft EPRI 1019196, NUREG-1921, "EPRI/NRC-RES Fire Human Reliability Analysis Guidelines" which largely replaces the human reliability analysis (HRA) guidance provided in EPRI 1011989, NUREG/CR-6850, Volume 2, Section 12. This module is suited for HRA/PRA practitioners responsible for the HRA 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. Simplified, but reasonably realistic examples of plant systems that may be represented in PRAs and manipulated by operators will be used to demonstrate the methodology.
  • Some familiarity with plant operations and operating procedures. Examples of HRA tasks, such as human failure event identification, will use typical operator actions and simplified examples of operating procedures to demonstrate the methodology.
  • A general understanding of the typical influences on operator performance and how they are represented in HRA tasks such as human failure event definition and quantification.
