液态熔盐堆以流动的氟化物作为燃料,燃料熔盐靠主泵驱动在主回路系统中流动,采用控制棒对堆芯功率进行控制。为研究液态熔盐堆堆芯功率控制,基于多节点建模方法,将熔盐实验堆堆芯划分为9个节点区域,建立熔盐实验堆堆芯非线性模型,并对模型进行线性化。基于堆芯线性化模型,采用PID控制方法设计堆芯功率控制系统,对堆芯反应性扰动等工况开展控制研究。结果表明,基于堆芯多节点模型设计的堆芯功率PID控制器可以实现对液态熔盐堆堆芯功率的良好控制。

The liquid molten salt reactor uses fluoride as fuel,and the fuel molten salt flows in the main loop system driven by the main pump.The control rod is used to control the core power.In order to study the power control of liquid molten salt reactor core,based on multinode modeling method,the core of molten salt reactor is divided into nine node regions,and the core nonlinear model of molten salt reactor experiment is established,and the model is linearized. Based on the core linearization model,the core power control system is designed by using the PID control method,and the control of the core...
