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...
