中文摘要：
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．Robinson2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-Ⅶ的BUGLE96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±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。
英文摘要：
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-Ⅶ. 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 4-0.04 with BUGLE-96. The result indicates that MUSE1.0 satisfies the accuracy requirement of fast neutron fluence calculation for RPV of PWR.
