MCNP程序在ADS屏蔽计算中的应用

Application of MCNP Code in the Shielding Calculation of ADS

摘要: 利用基于蒙特卡罗方法的MCNP程序计算了加速器驱动的次临界系统(ADS)中质子束管内的中子注量率分布以及通过质子束管顶端面和其它外表面逸出的中子注量率,得出了一些对ADS设计有意义的结论。

Abstract: By using MCNP code, the distributions of neutron fluence rate inside the pro ton beam duct and escaping from its entrance or other outside surfaces of accelerator driven sub-critical system (ADS) were calculated. Some conclusions are useful for the design of ADS.
