【Abstract】 The model and the mathematical formulation of the thermohydraulic performance in the steady state natural circulation of nuclear reactor systems was presented in this paper. And the analytical code of the natural circulation, named MISARS, was worked out. Using this code, the effects of the reactor parameters on the capacity of natural circulation were calculated and analysed in detail. The results obtained form the code are in good agreement with the theoretical analysis. The studies in this paper may supply some references for the design and operation of pressurized water reactors.更多还原
