| 摘 要： | 易裂变材料运输过程中重要的安全问题之一是临界安全。在对运输货包进行临界安全分析中必须要同时考虑多货包阵列形式、事故后货包损伤对临界安全影响、最佳水慢化条件等因素。本文采用MCNP程序针对CEFR-MOX新燃料组件运输货包进行了临界安全计算。计算结果表明:MCNP程序(采用核截面库为ENDF/B-V库)对本问题的次临界限值为0.924 6;正常运输条件下无限个运输货包的最大keff值为0.574 4,运输事故条件下无限个运输货包的最大keff值为0.659 7。根据临界安全指数的定义,确定CEFR-MOX新燃料组件运输货包的临界安全指数为0。

| Abstract: | Criticality safety analysis was carried out for the container loaded with fresh CEFR-MOX fuel assemblies using MCNP code and ENDF/B-V nuclear data. Several factors including package arrays, container damages under hypothetical accident condition and water moderation conditions were taken into account in criticality safety analysis of the transport of fissile material. The results show that the subcritical limit in this case is 0.924 6; the maximum keff of infinite packages array under normal situation is 0.574 4 and the maximum keff of infinite packages array under accident situation is 0.659 7. The criticality safety index (CSI) of fresh CEFR-MOX fuel assembly transport package is 0. |
