摘要
本文以后处理厂溶解槽、含拉西环溶液为例,通过分析其栅元特性,采取一系列合理近似,在现有的AMPX群截面库计算系统的基础上,寻找较为理想的栅元共振自屏及截面权重平均的近似处理方法,为最终迁移计算(或蒙特-卡洛模拟计算)提供较为满意的群截面库。从而为这类非常规栅元系统的临界安全分析开辟一条可靠途径。
In reprocessor, solution tanks, sometimes containing rasching rings, are always composed of anomalous cells. Based on AMPX code system and by analysing this kind of cells, the present work was done to find a rational approximate method for resonance self-shieldling analysis and cell homogenization. A reliable multigroup cross section library for transportation calculations is provided. It gives an useful method for critical evaluation of anomalous cells system.
