DEVELOPMENT OF A MULTIDISCIPLINARY FRAMEWORK FOR IMPROVING HUMAN RELIABILITY ANALYSIS

摘要

A multidisciplinary human reliability analysis (HRA) framework is currently beiAg--developed that more realistically represents the roles of humans in the initiai-ton, prevention and mitigation of accidents at nuclear power plants [1, 2]. This framework will support the characterization of errors of commission (EOCs) and human dependences as well as guide their representation (i.e., modelling and quantification) in probabilistic risk analyses (PRAs). The graphic description of the framework, illustrating the interrelationships between unsafe human actions, their impact on the plant, the incorporation of their impact in the PRA model, and the influences of the plant conditions and performance
