Verification of SIGACE Code for Generating ACE Format Crosssection Files with Continuous Energy at High Temperature
-
摘要: 以最新发布的ENDF/BVII.1评价库为基础， 使用SIGACE程序将低温ACE格式中子截面文件加工成较高温度的ACE格式文件， 生成了一个与温度相关的中子截面文档。 为校核截面数据， 选取ICT、 标准CANDU组件燃料温度反应性系数、 LWR栅格多普勒系数以及SEFOR基准题对SIGACE加工的核数据进行了验证。 基准题计算结果均与参考值符合较好， 表明SIGACE生成的高温度ACE格式截面数据可用于反应堆相关中子学参数的计算。 Based on the recently released ENDF/B-VII.1 library, high temperature neutron cross section files are generated through SIGACE code using low temperature ACE format files. To verify the processed ACE file of SIGACE, benchmark calculations are performed in this paper. The calculated results of selected ICT, standard CANDU assembly, LWR Doppler coefficient and SEFOR benchmarks are well conformed with reference value, which indicates that high temperature ACE files processed by SIGACE can be used in related neutronics calculations.Abstract: Based on the recently released ENDF/B-VII.1 library, high temperature neutron cross section files are generated through SIGACE code using low temperature ACE format files.
