摘　　要：蒙特卡罗方法对于复杂核系统的模拟具有明显优势,然而在实际工程应用中存在巨大的挑战,如复杂结构与材料分布精准建模难度大、计算收敛速度慢、海量数据难以及时有效分析等。超级蒙特卡罗核计算仿真软件系统SuperMC设计为支持以辐射输运为核心,包含燃耗、辐射源项/剂量/生物危害、材料活化与嬗变等的综合中子学计算,支持热工水力学、结构力学、化学、生物学等多物理耦合模拟。SuperMC目前已发展了精准建模、高效计算、四维可视化等关键技术,通过2 000余个国际基准模型及实验的验证与确认,在反应堆工程等方面获得广泛应用,本文对其发展概况进行介绍。Monte Carlo method has distinct advantages in simulating complicated nuclearsystems. However, great challenges to current MC methods and codes prevent its application in engineering projects, such as difficulties in the accurate modeling of complex geometries and material distribution, slow convergence of calculation, prompt and effective analysis of massive data. Super Monte Carlo Simulation Program for Nuclear and Radiation Process （SuperMC） is designed to perform the comprehensive neutronics calculation, taking the radiation transport as the core and including the depletion, radiation source term/dose/biohazard, material activation and transmutation, etc. It supports the multi-physics coupling calculation including thermo-hydraulics, structural mechanics, chemistry, biology, etc. Key techniques including automatic and accurate modeling, high efficient calculation, 4D visualization were developed and more than 2000 international benchmark models and experiments were used to verify and validate SuperMC. SuperMC has been widely used in reactor engineering projects and etc. In this paper, the overview of SuperMC development was introduced.
