一体化压水堆动态特性的仿真研究

研究了一体化压水堆堆芯模型的简化问题．用集总参数法建立了堆芯数学模型，包括中子动力学模型．反应性反馈模型和堆芯热工水力模型。得到了堆芯模型的增量式的传递函数方程组，并通过仿真对一体化压水堆和传统的分散布置压水堆的动态特性进行了比较，验证了模型的是合理性。

The Simulation Research for The Dynamic Performance of Integrated PWR

The mathematical model of the reactor core of integrated PWR has been studied and simpli- fied 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.
