摘　　要：介绍了高通量工程试验堆 (HFETR)堆芯三维稳态物理热工计算程序系统的验证结果。该程序系统由 6个部分组成 :基于WIMS D4的栅元均匀化少群参数计算程序、基于SIXTUS 3的三维堆芯燃料管理程序S3BURN、节块精细注量率重组程序HFETRPPC、堆芯流量分配计算程序HFETRFD、燃料元件流场和温场三维数值计算程序CASH以及基于COBRA 1V的燃料考验组件热工水力分析程序。通过程序计算值与实测值广泛范围的比较 ,对程序系统进行了验证。从结果可以看出 ,该程序系统功能强、性能好、计算速度快 ,可以完成HFETR及配套设施的堆芯运行方案设计计算。This paper describes the validation of the three - dimensional physical-thermal code system of HFETR. The six codes of this system are:the lattice homogenized few group parameters code based on WIMS-D4,the thr ee-dimensional core fuel management code S3BURN based on SIXTUS-3,the node fin e flux reconstruction code HFETRPPC,the core flow distribution code HFETRFD, the three-dimensional fuel assembly flow and temperature distribution numerical si mulation code CASH and the irradiation testing fuel assembly thermo-hydraulic a nalysis code based on COBRA-Ⅳ. Calculational results of the code system are gi ven and compared with measurements. It may be conclude that the code system has strong function,good performance and high speed. It has the ability for the job of HFETR and its associate facilities.
