摘要：在运用燃耗信任制技术进行乏燃料储存、运输等环节的临界安全分析时，临界计算所采用的条件是否具有足够的包络性十分关键。本文借助于OECD/NEA发布的若干燃耗信任制临界安全基准题，使用SCALE5.1软件中的STARBUCS模块进行分析，对信任核素选取、乏燃料冷却时间以及端末效应
等因索对乏燃料系统临界安全性的影响进行了研究，得出了各参数保守性的有关结论。关键调：燃耗信任制；核索选取；冷却时间；端末效应；轴向燃耗分布

Abstract, When applies the burnup credit technology to perform criticality safety analysis for spent fuel storage or transportation problems, it is important for one to confirm that all the conditions adopted are adequate to cover the severest conditions that may encounter in the engineering applications. Taking the OECD/NEA burnup credit criticality benchmarks as sample problems, we study the effect of some important factors that may affect the conservatism of the results for spent fuel system criticality safety analysis. Effects caused by different nuclides credit strategy, different cooling time and axial burnup profile are studied by use of the STARBUCS module of SCALE5. 1 software package, and related conclusions about the conservatism of these factors are drawn.
