Abstract: A new method of risk monitor system of a nuclear power plant has been proposed by Harbin Engineering University. The Risk Monitor provides a system stability overview and details about events that impact reliability. It calculates the reliability over the lifetime of the system. An important part of the risk monitor is monitoring the dynamic reliability of subsystems, which will help the plant operators to find the problems before real loss of service appears during the plant operation. The GO-FLOW is an important part of the knowledge base system of reliability monitor. In the present paper, available function of the GO-FLOW is explained and discussions are given for how to incorporate the GO-FLOW into the reliability monitor system. An interface between the GO-FLOW and the risk monitor system is a key point of the development of the total system. With well designed interface, operator (=analyst) can easily reflect the change of plant conditions to the evaluation results of risk monitor.
