摘要: 以最新的微观评价库CENDL-2.1为基础,用先进的群常数制作程序系统——NJOY来制作新的WIMS69群截面库,研究不同的 NJOY输入参数对 WIMS程序所计算的积分量的影响,并给出了详细的参数研究结果,同时还分析和讨论了计算结果与基准实验结果的比对.WIMS multi group constant library is the associated working library of WIMS/D4 lattice code, and it was created by using rather old and obsolete data based on ENDF/B3 (1972). Recently, the new evaluated data files such as ENDF/B 6.5, JEF 2.2, CENDL 2.1 and JENDL 3.2 were released. It s necessary to update the old library by the new evaluated data. The parameter study is performed to investigate the sensitivity of the integral parameters calculated with WIMS/D4 on the selection...
