The multi-level flow model is applied to the fault diagnosis of High-temperature gas-cooled reactor. Some basic concepts and operations of Causal Dependency Matrix (CDM) are introduced for state expression and state propagation based on MFM. The MFM symbols using CDM for MFM model are constructed with Simulink/MATLAB software. The fault diagnosis system was verified by the case of accidental acceleration of helium circulator trip. The fault diagnosis method can accurately analyze the system fault and give reasonable explanation. Keyword: multi-level flow model; fault diagnosis; HTR-PM; causal dependency matrix
