摘要
将基于节块法的三维时空中子动力学模型应用于船用堆堆芯物理仿真,建立了船用堆工程仿真模型。通过对掉棒事故瞬态过程的模拟分析表明:本文所建立的模型在满足船用堆工程仿真实时计算要求的同时可获得更高的计算精度,适用于局部反应性畸变较大问题的模拟分析。
Three-dimension space-time neutron kinetics model based on nodal method was applied in the simulation of core transient analysis,and the marine power plant simulation model was built.The results of control rod dropping accident analysis show that the model can satisfy the need of real-time engineering simulation with higher efficiency,and it has remarkable advantage in simulating transient process with large local reactivity disturbance.
