摘要：AbstractThe nature of risks is ambiguity, diversity and multilayer for the complicated artificial system which is composed by engineering systems and human organization. An idea of how to organize a new risk analysis system is proposed in this paper by applying IAEA’s five-layer Defense-in Depth (DiD) safety concept. Concretely, a method of how to configure integrated DiD risk analysis system is proposed to cope with the capability of treating complex nature of risks of various levels and modes in the behavior of the artificial system effectively. Application of the proposed idea will be conducted in future by an example practice of how to design distributed human interface system (HIS) for the support of safety operation of nuclear power plant.
