The heat-exchanger is a critical component that affects the efficiency and performanceof nuclear power plants. In order to make the surface heat-exchanger work under highefficiency and security, advanced simulation methods for heat-exchangers need to bedeveloped. Establishing high-precision simulation model of surface heat-exchanger is veryimportant for the development of high-precision nuclear power engineering simulator. Thisthesis took the surface heat-exchanger commonly used in nuclear power plant as object. Onthe basis of learning the structure of surface heat-exchanger and analyzing liquid flow andheat transfer behavior of feed-water heater,residual heat removal heat-exchanger andlubrication heat-exchanger, the distributed thermodynamic models of three types ofheat-exchangers were established. The corresponding algorithms were also selected.This model was evaluated by comparing with the design parameters of the QinshanPhase II NPP feed-water heater, Daya Bay NPP residual heat removal heat-exchanger andlubrication heat-exchanger. It was shown that the relative error between steady-statecalculation result and design parameters is within1%. In the end, these heat-exchangermodels were used to study the transient conditions of Qinshan Phase II NPP feed-waterheater, Daya Bay NPP residual heat removal heat-exchanger and lubrication heat-exchanger.The practicability of the model is proved through working out the characteristic curve ofheat-exchangers variation working-state feature. Then the dynamic response ofheat-exchangers in the step change of different control parameters were worked out. Thepredictions from the models were compared with the actual circumstantialities and theagreement was satisfactory.The results show that the heat-exchanger established models can satisfy with therequirements of engineering simulation analysis. These heat-exchanger models can also beused as a basic part of engineering simulator.
