| 摘 要： | 基于蒙特卡罗方法的MCNP程序,研究了反应堆屏蔽水箱失水过程中的水箱表面辐射剂量的变化情况.在屏蔽计算时为了节省计算时间,运用了堆芯均匀化方法,通过调整均匀化堆芯的核素密度和等效直径,使得均匀化等效堆芯在屏蔽水箱表面的中子和光子注量率与非均匀堆芯近似相同.

| Abstract: | Based on the Monte Carlo MCNP code,the changes of radiation dose at the shield water tank surface during the process of lost water is studied.For saving the time of calculation,the paper used the core homogenized method.And by adjusting the nuclide density and the equivalent diameter of homogenized core,the neutron and photon flux of homogenized core can be regarded the same as that of non-homogenized core. |
