摘要
采用WIMSD4 栅元程序及其国内通用的两个数据库计算了铀氢锆脉冲堆(TRIGA 堆) 的两种燃料栅元类型的栅元k ∞、能谱和各个核素的吸收率, 并与Monte Carlo 程序VIM 的结果进行了比较。比较结果表明, 对单棒栅元, WIMS 数据与VIM 吻合较好; 对束棒栅元, WIMS 计算模型对水中H 的吸收和栅元能谱的计算带来了误差; 对两种栅元, 用WIMSCNDC 库和WIMSIJS 库计算的k∞的最大误差分别为0-8 % 和- 1-7 % 。
The cell parameters of two kinds of TRIGA fuel are calculated with WIMS D4 cell code and two general libraries The calculations show that results for single rod cell are consistent with the VIM—a Monte Carlo code.An energy spectrum deviation appears for four rods cell due to model.The maximum deviation for k ∞with WIMS CNDC and WIMS IJS are 0.8%and -1.7%respectively.
