【摘要】 在MARIA程序移植、开发的基础上,通过编制INTERFACE接口程序,将69群群常数库与多群能谱、组件参数和反应堆临界计算的程序模块联接起来,组成了PWRCPS程序系统,使程序操作简便,使用方便。多种方案的计算结果表明,程序模块的联接是正确的。按Sn(n=6)中子输运理论和两维(x,y)两群扩散模型,完成10个由不同的PWR组件装载的反应堆临界计算,所需总的机时小于1500s(CPU),计算速度很快。更多还原

【Abstract】 PWRCPS is a program system of PWR criticality calculation. The 69 multi-group constants li-brary, the multi--group spectrum module, the assembly group parameters module and the reactor criti-cality module are combined into the program system by the INTERFACE program, so the programoperation is convenient. The correctness of interface among the modules is verified by the PWR criti-cality calculations. The total CPU time is less then 1500s for the PWR criticality calculations of tendifferent cases, the run speed is fast.更多还原
