摘　　要：为了检验HENDL2.1/CG数据库的制作方法,并测试主要易裂变核截面的可靠性,使用自主研发的大型集成多功能中子学计算与分析系统VisualBUS和《国际临界安全基准评价实验手册》中的基准临界例题,对HENDL2.1/CG数据库中的233U2、35U2、39Pu2、37Np和244Cm五个易裂变核素进行了校核。计算结果与实验结果进行了对比,相对误差在0.5%左右,验证了HENDL2.1/CG数据库能群结构和权重谱合理,主要易裂变核素截面数据可靠。To validate and qualify the reliability of the process of producing HENDL2.1/ CG and test the reliability of some major fissional nuclides cross sections＇ reliability, the evaluated critical benchmark experiments including some major fissional nuclides of HENDL2.1/CG data library, such as ^233U, ^235U,^239Pu, ^237Np and ^244Cm, were simulated using the home-developed integrated multi-functional neutronics calculation and analysis system VisualBUS. By the comparison with the experimental results in the International Handbook of Evaluated Criticality Safety Benchmark Experiments, HENDL2.1/CG data library are validated and qualified to be reliable.
