摘　　要：组件均匀化参数的计算是核供热堆物理设计及堆芯燃料管理计算的基础。本文介绍的组件均匀化参数计算的处理方法是以先进的燃料组件软件包ＴＰＦＡＰ为基本工具，对于堆内各种类型组件计算少群截面，按Ｇｄ２Ｏ３不同重量百分比、比燃耗、能群等顺序组成参数截面表，再用函数插值法求得全堆燃耗计算所需的截面。实践表明，用该方法处理的参数计算燃耗的结果可满足工程设计精度要求，它对燃料管理及优化设计计算是极为有效的方法。The calculation of homogeneous parameters is the basis of physics calculation in nuclear heating reactors(NHRs).The method of calculating homogeneous parameters obtained in this paper is the advanced fuel assembly software,TPFAP, which is the base tool. The few group section is calculated for several in core assemblies,and the parameter section table is ordered by different Gd 2O 3 weight percent, burnup, energy group, and then the necessary sections for in core burnup are calculated with function interposition method. Practically, the solutions of burnup calculated with the parameters given by this method are satisfactory with the requirement of engineering design precision, and it is a very effective method for fuel management and optimization design.
