MCNP程序研究进展

Developments of Research on Code MCNP

摘要: MCNP是用来计算中子、光子、电子或者中子/光子/电子耦合问题的通用蒙特卡罗粒子输运计算程序，它以其灵活、通用的特点以及强大的功能，在诸多领域得到广泛认可和应用。但是由于其使用需要较强的专业水平，因而使得其在某些方面又显出一些弱点。对MCNP程序的发展过程以及今后的发展趋势进行了讨论，同时提出了作者的观点。

Abstract: MCNP is a generalpurpose Monte Carlo NParticle code that can be used for neutron, photon, electron or coupled neutron/photon/electron transport, and it is widely accepted and used in many fields for its features of flexibility, generality and powerful functionality. However, MCNP shows some weakness in some aspects due to its professionusing. In this paper, both the procedure of MCNP development and its tendency are expounded, while the author’s point of view on MCNP code is put forward.
