The model of nuclear power plant primary and secondary circuits was established, taking Qinshan Unit 1 as the object. The fault of SG U-tube rupture was calculated based on RELAP5 for solving the fault data source problem. Through analyzing the calculation results, we can know that simulation node is reasonable, input data card is exact, and data based on this model is credible. The designed data combining with fault diagnosis system has been debugged. The result indicates that the data is exact and enough and can be one of the databases for study on fault diagnosis of nuclear power plant.
