摘　　要：KYLIN-V2.0是中国核动力研究设计院自主研发的一款先进中子学栅格物理程序,本文利用日本原子能机构发布的JAEA基准题中的燃料单栅元及载钆UO2燃料组件等基准问题对程序进行了验证分析。数值结果表明:KYLIN-V2.0程序计算得到的有效增殖因子、重要核素的原子核密度及裂变率分布等结果与基准题给出的国际上其他知名程序的计算结果吻合良好;表明KYLIN-V2.0程序满足燃料组件中子学参数计算精度要求,可用于科研和堆芯设计工作。KYLIN-V2. 0 is an advanced neutron transport lattice physics code developed by Nuclear Power Institute of China( NPIC).Verification of KYLIN-V2. 0 code has been made by the analysis for JAEA benchmark problem with fuel single pin and UO2 fuel assembly within burnable poison gadolinium, which was released by the Japan Atomic Energy Research Institute. The numerical verification results show that the effective multiplication factor,atomic nucleus density of important nuclides and fission rate distribution that are calculated by KYLIN-V2. 0 are in better agreement with the calculation results of other international known codes given by the benchmark;Which indicated that KYLIN-V2. 0 code meets the neutrons parameters requirement of fuel assembly, and it can be used for scientific research and nuclearreactor core design.
