An Implementation of Operational Experience Analysis for Addressing Human Reliability Analysis Issues in Nuclear Power Plants

Human reliability analysis (HRA) is an integral part of probabilistic risk assessments (PRAs). Although various approaches and methods have been proposed since the first HRA was performed almost four decades ago, the technology associated with HRA is still not fully developed. The limitations of the existing HRA approaches become particularly apparent when the role of the human is examined in the context of nuclear power plants (NPPs). HRA approaches in the cognitive perspective try to take into consideration the operator, the system and their interactions. Cognitive models can help in analyzing human mental processes that can lead to error. This study documents the implementation of operating experience analysis in nuclear domains and describes the future improvement of HRA approaches. This review provides a summary of the HRA literature in order to the field of HRA approaches. Researchers may have knowledge of the capability of the tools and an understanding of their strengths and weaknesses in variety types of nuclear reactors
