考虑到液态熔盐堆中熔盐燃料在主回路系统中流动,堆芯出口处燃料温度可有效表征堆芯运行状态。因此,为开展对液态熔盐堆堆芯出口温度控制的研究,直接采用堆芯微分方程组,设计一种基于堆芯出口温度控制的运行策略。基于堆芯微分方程模型,设计堆芯出口温度控制器,并基于Matlab/Simulink建立堆芯仿真系统。以MSBR堆芯为对象,开展堆芯反应性扰动、堆芯进口温度扰动、堆芯出口温度跟踪的仿真。分析表明,基于堆芯出口燃料温度控制策略设计的模糊PID控制器可以很好地实现堆芯稳定运行。

Considering the flow of molten salt fuel in the main loop system of liquid molten salt reactor,the core fuel temperature can effectively represents the core operation state.Therefore,in order to study the core outlet temperature control of liquid molten salt reactor,a core outlet temperature control strategy based on differential equations is designed.Based on the core differential equation model,the core outlet temperature controller is designed,and the core simulation system is established based on MATLAB/Simulink.The simulation of reactor core reactivity disturbance,core inlet temperature d...
