铀富集厂容器取料过程中的核临界安全计算

Calculation of Nuclear Criticality Safety for Duration of Materials Handling from Container at Uranium Enrichment Plant

介绍了在中国核工业集团公司兰州铀浓缩厂的核燃料生产中 ,针对某容器取料过程中存在的核临界安全问题 ,采用蒙特卡罗方法 KENO 程序进行的计算。通过计算表明 ,某容器在取料过程中 ,在保护杯起作用的情况下 ,是可以保证临界安全的 ,从而解决了该厂核燃料生产中 。

Monte Karlo KENO Ⅳ program was used to calculate nuclear criticality safety in taking materials from the materials container during nuclear fuel production at a uranium enrichment plant. The results show that nuclear criticality safety can be ensured during materials handling when protection cup being effective, thus leading to a solution to nuclear criticality safety problem in duration of container materials handling.
