摘要
国际热核试验堆(ITER)核分析的主要计算工具是三维蒙特卡罗输运程序MCNP。MCAM(MCNP Auto-Modeling system)作为MCNP自动建模与可视化软件,其主要功能是CAD模型与MC-NP计算模型之间的数据交互。一方面MCAM可将通用格式的CAD模型转换成MCNP计算模型,另一方面作为一个可视化工具,它可以以CAD模型的方式显示MCNP计算模型中几何及材料等相关信息。主要介绍利用MCAM对ITER三维MCNP模型的改进,主要包括:包层模块的重建和内包层几何细化;模型环向角度从20°到40°的扩展。
In order to conduct nuclear analyses on neutronics issues for ITER （International Thermonuclear Experimental Reactor） , a standard three-dimensional model of the ITER reactor is being developed. The complex nuclear analyses are conducted by MCNP/4C in three dimensions. MCAM （MCNP Auto-Modeling system） , as an implementation of the interface code between modern CAD system and MCNP, is a modeling and visualization tool which can convert a CAD model to neutronics model for MCNP and vice versa. This paper presents the application of MCAM to modify ITER 3-D neutronics model, which include blanket segmentation update, incorporation of fine structures of inboard blanket and the model extension from 20° to 40° in toroidal direction.
