我们开发了一个CAD/MCNP接口程序原型，可以使用详细的计算几何结构轻松地进行高精度的蒙特卡罗聚变核设计计算。通常，在实体区域上只有CAD数据。然而，CAD空区数据必须输入到MCNP。我们新开发的CAD/MCNP接口程序自动生成空区数据。通过使用布尔运算减去实心区域数据来创建空心区域数据。该程序还具有将整体数据均匀划分为小立方体的功能，以简化空洞区域数据。它已被应用于创建3D CAD数据在ITER基准模型。结果表明，使用我们的程序成功地创建了ITER模型中的空洞区域的数据。
We developed a CAD/MCNP interface program prototype to easily perform Monte Carlo fusion nuclear design calculation with high accuracy using detailed calculation geometry. Usually, there is only CAD data on the solid region. However, CAD void region data must be input to MCNP. Our newly developed CAD/MCNP interface program creates the void region data automatically. The void region data is created by subtracting the solid region data using Boolean operations. The program has also the function of uniformly dividing the overall data into small cubes to simplify the void region data. It has been applied to create 3D CAD data in the ITER benchmark model. It was demonstrated that data of the void region in the ITER model were successfully created using our program.
