摘　　要：用由ＥＮＤＦ／ＢⅣ产生的ＺｒＨ中Ｈ及Ｅｒ等元素的６９群群常数，补充了ＷＩＭＳＤ／４库中的核数据，形成了用于铀氢锆脉冲堆计算的ＷＩＭＳＣＮＤＣ库。校核了该库中ＺｒＨ中Ｈ的散射截面，并利用该库及栅元计算程序ＷＩＭＳＤ／４，计算了铀氢锆脉冲堆燃料栅元的能谱、群常数、ｋ∞、功率分布以及温度系数。最后用一维两群扩散程序ＴＲＩＧＡＰ进行了堆芯临界计算。以上结果均与有关文献符合得很好。The 69 groups constants of H in ZrH and Er generated from ENDF/B Ⅳ library are maked up into WIMS D/4 library.WIMS CNDC library is obtained which used on uranium zirconium hydride reactor calculation.The scattering cross section for H in ZrH is checked.The energy spectrum,group constants,k∞,power distribution and negative temperature coefficient of uranium zirconium hydridereactor fuel cell are calculated.The critical core is calculated by TRIGAP coed.These results agree very well with those of references.
