Abstract

Considering characteristics of nuclear power plant digital instrumentation and control system, challenges of reliability assessment of digital instrumentation and control system are pointed out. As for its dynamic behavior and multi-states failure mode, limitation of traditional methods, research status and applicability of dynamic flowgraph methodology and other advance dynamic reliability assessment approach were introduced and compered. It´s concluded that Dynamic flowgraph methodology maybe the dominant one in future after simplify its model procedure and reduction computational cost of its deductive analysis.
