摘要
辐射屏蔽计算是核工程设计的核心内容之一。MCNP是最常用到的屏蔽计算软件,但MCNP在处理深穿透问题上存在一定困难,计算误差较大。本文以简单的深穿透屏蔽计算为例,介绍了MCNP的减方差技巧在深穿透屏蔽计算中的应用效果,并提出了一种应用减方差技巧进行深穿透计算的思路。
The radiation shielding calculation is the core content in the design of nuclear engineering. MCNP is the most widely used shielding calculation code. But it has some difficulties when dealing with deep penetration shielding calculation. For solving this problem,a series of variance reduction techniques in MCNP are experimented and a new thought based on variance reduction technique for deep penetration shielding calculation is introduced.
