Aiming at the problem of concurrent fault diagnosis of small modular reactor(SMR),a concurrent fault diagnosis method based on knowledge matrix for knowledge expression and reasoning is proposed.This method gives an efficient expert knowledge expression,which transforms the complex logical reasoning of traditional expert system into simple matrix operation,improves the efficiency of fault diagnosis,and can meet the requirements of online concurrent fault diagnosis of SMR.The effectiveness of this method is proved by the diagnosis examples of main coolant pipeline damage and control rod failure in SMR.
