燃料组件少群参数计算程序AFGPB及其基准验证

Fuel Assembly Few Group Parameter Calculation Code AFGPB and Benchmarking

介绍了自行开发的反应堆燃料组件少群参数计算程序AFGPB的理论方法和模型,并利用IAEA板元件组件基准问题对其进行了验证分析,同时给出了TPFAP和CPM程序对美国CE公司燃料组件功率分布的校算结果。结果表明,AFGPB的计算值与国际上其他机构的结果符合良好。

This paper briefly introduced theoretical model and methodology of the reactor fuel assembly few group parameter calculation code AFGPB. The verification and validation of the code have been made by calculations of the IAEA plate-type fuel assembly benchmark problem and comparisons are made with the power distribution for CE company fuel assembly between the calculation values of the AFGPB, TPFAP and EPRI-CPM codes . The numerical results indicated that the calculated values of AFGPB are in good agreement with those of other international organizations.
