摘　　要：利用IAEA及文献提供的俄罗斯WWER-1000反应堆燃料组件计算的基准问题,对我国研制的压水堆六角形组件均匀化参数计算软件TPFAP-HEX进行了校核计算。通过和CASMO-HEX以及俄罗斯库尔恰托夫研究院等国外研究机构在组件k_∞、栅元的功率分布以及各种反应性效应等方面的比较,可以初步得出结论:TPFAP-HEX软件的研制是成功的,它基本达到了工程计算的功能和精度要求。The hexagonal assembly homogenization code TPFAP-HEX has been verified in this pa- per by comparing the numerical results with those of Russia WWER-1000 fuel assembly bench- mark problems provided by IAEA and some literatures. By comparison with CASMO-HEX and some foreign research institutions, such as Kurchatov Institute, about the fuel assembly k∞ .cell power distributions and some kinds of reactivity affections, a conclusion can be made: the assem- bly code TPFAP-HEX is successfully developed, lt satisfies the function and precision require- ments in the engineering.
