摘要
建立堆芯闭式组件与开式组件的自然循环流量分配的瞬态计算模型,用以计算堆芯各组件的热工水力参数及组件的均匀化物理参数的瞬变值,实现堆芯一维热工水力与三维时空中子动力学计算程序的耦合计算。利用包含所建数学模型的分析程序对典型工况下自然循环及其过渡过程进行计算分析,结果表明主要参数的计算值和试验数据吻合较好。
Transient calculation models of core flow-rate distribution of natural circulation were established for shelled and unshelled fuel assemblies,which can calculate thermal-hydraulic and homogenization physics parameters of assemblies in the core.And coupling calculation of one-dimension thermal-hydraulic and three-dimension space-time neutron kinetics of core was achieved.Representative condition of natural circulation and its transient process was calculated and analyzed by programs embedded with the models,and the results indicated that the calculation of main parameters was well fitted with the experimental data.
