Research on Cognitive Reliability Model for Main Control Room Considering Human Factors in Nuclear Power Plants

Facing the shortcomings of the traditional cognitive factors and cognitive model,this paper presents a Bayesian networks cognitive reliability model by taking the main control room as a reference back-ground and human factors as the key points.The model mainly analyzes the cognitive reliability affected by the human factors,and for the cognitive node and influence factors corresponding to cognitive node,a series of methods and function formulas to compute the node cognitive reliability is proposed.The model and cor-responding methods can be applied to the evaluation of cognitive process for the nuclear power plant opera-tors and have a certain significance for the prevention of safety accidents in nuclear power plants.
