SIMULATION AND VALIDATION OF THE IMPROVED DYNAMIC MATHEMATICAL MODEL FOR THE PRESSURIZER PRESSURE CONTROL SYSTEM OF THE AP1000 NUCLEAR POWER PLANT
According to the characteristics of the pressurizer dynamic process of nuclear power plants, a threeregion model of pressurizer pressure control system for nuclear power plant is established on the base of the SNERDI control system model in this paper, for the purpose of the improvement of the two-region model. Simulation experiments have been performed using acslX software according to the actual data of the CHASHMA nuclear power plant unit-2. By the comparison between the simulating results and the data of the CHASHMA nuclear power plant unit-2 in Pakistan, the three-region model has been proved to be more precise than the traditional two-region model. A three-region model and a two-region model of AP1000 pressurizer are established with the use of AP1000 nuclear power plant data afterwards. The simulation results have been compared between the two models. The improved model can be used for future simulation of CAP1400 pressurizer.
