Abstract: The relationship between the control system of the nuclear power plant (NPP) and the condition monitoring system which provides support for the operator is very close, but in most nuclear power plant design, these two systems are designed separately, which affects the system compatibility, the utilization efficiency of the system resources, the extendibility of the systems and the real–time nature of the support, and may have some negative impacts on the plant operation. Focusing on this problem, an integrated design concept for the NPP control system and condition monitoring system is proposed in this paper. The overview scheme of the integrated system is given based on the analysis of the functions required. Furthermore, the study for modeling of the integrated control and condition monitoring system using the IDEF(Integration Definition Language) and UCM (Use Case Maps) methods is introduced in this paper.
