压水堆核电站堆芯集中参数模型的微机仿真

Microcomputer simulation of the centrality parameter modeling for PWR nuclear power plant reactor core

阐述了 PWR核电站堆芯的模型化问题 ,提出了适用于微机仿真的核电站堆芯的物理数学模型。将核电站堆芯分为三大块分别建立模型 :中子动力学模块、反应性反馈模块、堆芯热力学模块。建立系统传递函数 ,运用 MATLA仿真 。

The paper reports the model of the reactor core of the PWR nuclear power plant and established the suitable core physics mathematics model for microcomputer simulation. Set up the neutron dynamic model; reactivity feedback model; corn thermodynamics model. Found the system transfer function use MATLAB simulating and get the result.
