基于ENDF/B-Ⅶ.0评价核数据库开发了172n×42g多群截面数据库MUSE1.0,利用二维离散纵标法程序DORT,针对美国H.B.Robinson-2号机组压力容器基准实验,对辐照监督管处中子能谱、核反应率及比活度等参数进行了详细的计算分析,并与基于ENDF/B-Ⅵ的BUGLE-96多群参数库计算结果及实验测量值进行了比较分析.结果表明:MUSE1.0比活度计算值与实验测量值之比(C/M)平均为0.98土0.04,较BUGLE-96计算结果(平均C/M为0.90±0.04)精度有较大提高,满足压水堆压力容器快中子注量计算精度要求.

Multi-group library MUSE1.0 based on the ENDF/B-Ⅶ. 0 was developed.The key responses, such as neutron spectrum, reaction rate and specific activity of the surveillance capsule benchmark of H.B. Robinson unit-2 in the USA were calculated by the two-dimensional discrete-ordinates code DORT. The results were compared with those calculated by the BUGLE-96 cross section library which was based on ENDF/B-Ⅵ. The average ratio of calculated-to-measured (C/M) specific activities with MUSE1.0 is 0.98±0.04, which is more accurate than the value of 0.90±0.04 with BUGLE-96. The result indicates that MUSE1.0 satisfies the accuracy requirement of fast neutron fluence calculation for RPV of PWR.
