According to the specific structure of a marine reactor pressurizer and its operating characteristics of frequent pressure and water level fluctuation, a new non-equilibrium four region mathematical and physical model is established for the first time to fulfill the aim of fast and precise simulation. The model includes the bubble rising, condensate dropping, wall condensation and heat transfer through outside wall while the heat and mass transfer at the liquid and gas interface is neglected. The initializing program is also introduced. The Simulink is adopted as the simulating tool and the corresponding Simulink module is established. The simulation proves to be very fast in a common microcomputer, which indicates that Simulink is efficient and is suitable for the fast simulation of marine reactor with the characteristics of frequent variations of power and corresponding physical and thermal parameters. A typical process with surge flow varying very acutely and complicatedly is adopted as an example. The variation of the pressure and the water level of the process by the new model agree well with the results of Relap5/Mod3.3, which proves the validity of the model and some simplification adopted. As one of the main parts of the fast simulation program under development for in the operating field use for a marine nuclear power plant, the achievement of the fast simulation of the pressurizer is of significant importance.
