用于TRIGA堆计算的WIMS-D/4核数据库的评价

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． The 69 groups constants of Hin ZrH,166Er and 167Er generated by NJOY and GASKET codes are inserted into WIMS nuclear data library WIMS CNDC and WIMS NINT libraries used on RTIGA rector calculation are obtainedIn order to check WIMS CNDC and WIMS NINT libraries,the scattering cross section is compared with that in WIMS IJS li brary.The group constant,K->∞ and temperature coefficient are calculated by using WIMS C NDC,WIMS NINT and WIMS IJS.The results show the both libraries are...
