The Simulation Research for The Dynamic Performance of Integrated PWR

The mathematical model of the reactor core of integrated PWR has been studied and simplified properly in this paper. With the lumped parameter method, we have established the mathematical model of the reactor core, including the neutron dynamic equation, the feedback reactivities model and the thermo-hydraulic model of the reactor. Based on the above equations and models, the incremental transfer functions of the reactor core model have been built. By simulation experimentation, we have compared the dynamic characteristics of the integrated PWR with the traditional dispersed PWR. The simulation results show that the mathematical models and equations are correct.
