MCAM在ITER装置TRIPOLI三维中子学建模中的应用

Applications of MCAM for ITER TRIPOLI 3D neutronics modeling

目前,国际热核聚变实验反应堆ITER装置仅有针对MCNP程序的三维中子学基准模型(ITERA-lite4),因此无法使用TRIPOLI程序对ITER装置进行中子学计算分析。本文利用蒙特卡罗计算自动建模软件MCAM 5.1创建ITER装置的三维中子学TRIPOLI模型,并通过TRIPOLI程序对其进行中子学计算分析。计算结果与基于ITER A-lite4的MCNP计算结果吻合良好,从而验证了所建模型的正确性。

At present, the ITER 3D neutronics reference model （named ITER A-lite4） is only for MCNP code. In order to use TRIPOLI code to do neutronics analysis of ITER, the 3D TRIPOLI model needs to be created. This paper presents the application of monte carlo automatic modeling program for particle transport simulation （MCAM） version 5.1 to build the ITER 3D neutronics TRIPOLI model. The calculation results of the model performed by TRIPOLI code were consistent with the calculation results of ITER A-lite4 by MCNP code, which demonstrated the correctness of the ITER TRIPOLI model.
