乏燃料桶外部剂量的MCNP分析

The External Dose of Lack Fuel Cask for Analyses with MCNP

乏燃料运输容器是运输反应堆乏燃料的专用设备。文章使用MCNP4C软件计算西屋MC-10乏燃料桶的外部剂量率,方法是基于网格的定义,得到桶周围外部整体剂量率,并与前研究工作者Georgeta Radulescu的计算结果相比,结果一致性符合较好,使用网格造成机时耗费较大,也存在一定误差,但能够比较全面,详尽地得到关于乏燃料桶外部剂量的一些数据,可以对工作人员确定乏燃料桶外部剂量有一定的参考意义。

The transport vessel of lack fuel cask is a special facilities which is for reactor lack fuel transportation. MCNP4C is used to count the external dose rate of Westinghouse MC-10 lack fuel cask, it is based on mesh definition, to get the whole external dose rate of the cask, and in connection with the resuit from previous researcher Georgeta Radulescu, the outcome in consistency is good, using mesh causes long-playing machine hours and comes to some error, but it can get many data about external dose rate of the lack fuel cask roundly and at any rate. So it makes sense to the definition on the external close rate of the lack fuel cask for missionary.
