摘要
利用ITER三维基准模型对蒙特卡罗方法粒子输运自动建模软件MCAM4.2进行了检验测试,实现了CAD工程模型的预处理,自动转换生成MCNP计算输入文件,并完成测试要求的中子壁负载和偏滤器中子注量率与核热沉积的计算。ITER模型的成功处理与计算表明MCAM能够正确和有效地处理大型复杂几何模型。
MCAM （Monte-Carlo Automatic Modeling System） is an integrated tool, developed by FDS Team, for CAD model preprocessing, bi-directional conversion between CAD/Monte Carlo （MCNP/TRIPLO etc. ） neutronics models. The ITER （International Thermonuclear Experimental Reactor） benchmark model is set by ITER International Team（IT） to compare the CAD/MCNP programs developed by different ITER participating teams. The benchmarking of MCAM4.2 has been carried out by using the ITER benchmark model. This paper introduces the benchmark procedure of MCAM4. 2 and presents the nuclear response of neutron wall loading on the first wall and the neutron flux and nuclear heating in the diverter cassette. The results show that MCAM can correctly and effectively process the large scale and complex ITER three-dimensional model.
