Current State and Approaches to Further Development of Methods for Human Factors in Probabilistic Safety Assessments

Abstract

Human interactions attract growing attention in the context of safety analysis. They are widely recognized as an important factor when evaluating the reliability and safety of complex industrial facilities such as nuclear power plants. This fact has been reflected in several probabilistic safety assessments (PSAs), often leading to the conclusion that human errors significantly contribute to the estimated risk level of the plants. Therefore, the modeling of human factors in PSA is an important topic. The current state of human reliability analysis and necessary issues for the further development of models and methods are described.
