MCNP源程序修改及应用

MCNP程序是一个大型多功能蒙特卡罗计算程序,它适应于核科学和工程方面的多种课题.虽然MCNP程序的通用性很强,可以满足大多数的实际应用,但针对一些特殊的应用还是需要用户对源程序进行修改并重新编译.目前,大多数MCNP程序用户对如何修改和编译源程序了解得比较少,与之相应的文献资料也很少见.有鉴于此,本文对该问题进行了总结并对如何处理作了详细的介绍,目的是为用户更好的理解程序构成、提高对程序的应用能力提供帮助.

Modification and Application of MCNP4C Source Code

The MCNP code is a big and powerful Monte Carlo N-particle transport one which is widely used in the nuclear science and engineering design.It is very general and can satisfy most applications in many fields.But,for some particular users,the code has to be modified and recompiled.At present,most users still do not know how to do that and there are also few references about it.In this paper the method is introduced in a detail,which will be helpful for the MCNP code users to better understand its structure and mechanism.In addition,two application examples are given in this paper to improve the users' ability of using this code.
