输运问题蒙特卡罗模拟方法回顾及展望北大核心CSCD

蒙特卡罗(MC)方法具有复杂几何处理能力强,方法通用灵活,核数据完备,模拟忠实于物理过程等特点,成为中子学数值模拟的首选方法之一。在核能领域,MC方法得益于计算机的快速发展,在辐射屏蔽、反应堆堆芯临界安全分析、乏燃料后处理、放射性废物处置、核设施退役、核事故应急、放射性石油测井、核医学等领域均有广泛应用。对MC方法及软件输运计算做简要回顾,并对未来发展进行展望。

Retrospect and outlook of Monte Carlo simulated methods for transport problems

Monte Carlo method is becoming the first choice of particle transport simulation methods because of its strong capability of complicated geometry treatment, perfected nuclear data and universal property. Monte Carlo softwares have been rapidly developing with the development of computers and at present, they are widely used in applications sa radiation shielding, criticality safety analysis, post-treatment of spent fuel, radioactivity waste treatment, decommissioning retire of nuclear facilities, emergence of nuclear accident, nuclear well-logging and nuclear medical science, etc. This paper provides a brief introduction of the development of Monte Carlo simulations in the past and at present and perspectives about its future.
