摘要

为进行燃料组件的辐照性能分析,需要提供导向管或燃料栅元快中子注量。本文针对目前SCIENCE软件堆芯计算结果中不能给出组件内pin-by-pin的中子注量问题进行分析研究,首先通过蒙卡程序计算分析寿期末燃料栅元燃耗深度与寿期末快中子注量之间的关系,以及寿期末导向管栅元快中子注量与周围燃料栅元快中子注量之间的关系。然后根据这两个关系,通过SCIENCE结果中寿期末燃料栅元燃耗深度分布即可得到导向管栅元快中子注量分布。
        In order to analyze the radiation performance of fuel assembly, the fast neutron fluence of guide tubes or fuel grid elements should be provided. At present, there is a problem of that the pin-by-pin neutron fluence of the assembly can not be given in calculation results of SCIENCE, but it can provide the burnup distribution of the assembly. In order to obtain the fast neutron fluence in guide tube at the end of life, in this paper,the relationship between the burnup of fuel elements and the fast neutron fluence of fuel elements at the end of life was studied by Mote Colo program RMC, so was the relationship between the fast neutron fluence of the guide tube and that of fuel elements around. And then according to these two relations, the fast neutron fluence in guide tube can be obtained by the burnup distribution of fuel elements at the end of life in the SCIENCE results.
