摘要
为在堆外实验中实现核释热实时模拟,编制了相应的模拟控制程序,其中的反应性模拟子程序采用了点堆模型、一维均匀流模型和瞬态导热模型来模拟慢化剂温度效应和多谱勒效应。用此程序完成了降流量和升功率两项实验,实验结果表明:该程序能够满足核释热瞬态特性模拟的要求。
A simulation program was designed for real-time simulation of nuclear-heat-release in out of pile experiment. Nuclear reactivity simulation program, a subprogram of simulation program, utilized three main models to simulate Doppler effect and moderator temperature effect, that was point-reactor model for neutron dynamic, one-dimensional homogenous flow model for hydrodynamic and one-dimensional transient heat conduction model for fuel dynamic. Two experiments, raising power and lowering flow, were performed, which used that program. Experimental results show that the program can meet the requirement of real-time simulation of nuclear-heat-release.
