摘要/Abstract

摘要： 新燃料组件运输过程中最主要的核安全问题是临界安全。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、事故后货包损伤情况、最佳水慢化条件等因素。本文采用MCNP程序针对美国西屋公司XL型运输容器装载AP1000新燃料组件货包的实例进行了临界安全计算。结果表明,在XL型运输容器设计许可书中允许装载货包数N=75的限制条件下,临界安全是有保障的。

Abstract: Criticality safety needs to be considered carefully during the transport of intact nuclear fuel assemblies. Several factors should be taken in to account, such as package arrays, container damages under hypothetical accident condition and water moderation conditions. In this work, criticality safety analysis has been carried out for a Westinghouse XL shipping container loaded with AP1000 fuel assemblies. The fuel assembly and transport container have been modeled and simulated using the MCNP code. The results of MCNP show that the Westinghouse XL package is subcritical, if the number of packages meets the requirements in the approval of the competent authority.

Key words: AP1000 fuel assembly, transport package, criticality safety analysis
