Evaluation of WIMS-D/4 Unclear Data Library Used on TRIGA Reactor Calculation
-
摘要: 分别应用NJOY和GASKET程序将ZrH中H、166Er和167Er核素的69群微观截面补充到WIMS程序的核数据库中,形成了用于TRIGA堆计算的WIMS-CNDC库和WIMS-NINT库.为了评价这两个核数据库是否正确,将它们与国际上通用的TRIGA堆计算库WIMS-IJS作了比较,验证了氢化锆中氢的声子特征;采用上述三种库分别计算了TRIGA堆燃料栅元(标准-8.5燃料元件、标准12燃料元件、LEU燃料元件和FLIP燃料元件)的群常数、倍增因子随燃耗的变化以及燃料的负温度系数,并对结果进行了分析比较.结果表明,WIMS-CNDC库和WIMS-NINT库适用于TRIGA堆的计算.
