The simulator experimental study on the operator reliability of Qinshan nuclear power plant

摘要

The scarcity of human failure data is a major problem that embarrasses human reliability analysts for a long time. In the human reliability analysis of Qinshan nuclear power plant, a full-size simulator was used to conduct an experiment on the operator's reliability. The experiment involves 23 abnormal events and 55 human interactions covering 3 cognitive types: skill-based, rule-based and knowledge-based. The response time and conditions of 38 operators were recorded and the data were analyzed and processed to develop human cognitive reliability model parameters, which match with the features of Qinshan nuclear power plant system and its staff. This paper introduces the background, theory, methods, process, conclusion of the experiment and their comparison with data obtained abroad.
