Since the early 1970s, Human Reliability Analysis (HRA) has been considered an integral part of Probabilistic Risk Assessments (PRAs). However, current limitations of existing HRA approaches become apparent when the role of the human is explicitly examined in the context of real nuclear power plant (NPP) events. Recent serious events indicate that human performance is a dominant source of plant risk. Development of new or improved HRA methodologies to more realistically represent human performance is recognized by the Nuclear Regulatory Commission (NRC) as a necessary means to increase the robustness of PRAs. In order to accomplish this objective, a Detailed HRA Project, under sponsorship of the NRC`s Office of Nuclear Regulatory Research (RES), was initiated in late February of 1992 by Brookhaven National Laboratory (BNL). The purpose of the BNL Detailed HRA project is to develop an improved method for HRA that enables a more realistic assessment of the human contribution to plant risk and can be fully integrated with PRA. This paper describes the research and development efforts of the project including: the development of a multidisciplinary HRA framework, the characterization and representation of errors of commission, and an approach for addressing human dependencies. Research implications and necessary development requirements are also discussed.
