Abstract

Abstract

Based on the analysis of Secondary System of Nuclear Power Plants,a MFM model of Secondary System is established in this paper.Utilizing Visual C++,together with the theory of MFM model and CDG consequence analysis method,a trial fault diagnosis system is built and two simulation cases are used for the evaluating of the fault diagnosis performance.The emulation test proves that the system is able to identify the potential root fault exactly and have the advantage of high vision and understandability.
