摘要: 介绍了中国科学院等离子体物理研究所与德国Forschungszentrum Karlsruhe合作开展的国际聚变材料辐照装置（IFMIF）屏蔽中子学方面的相关设计研究工作。重点介绍了新开发的三维耦合屏最计算方法，包括其基本原理和程序系统等，以及基于该方法的IFMIF的三维屏蔽计算典型结果与分析。The International Fusion Materials Irradiation Materials Irradiation Facility （IFMIF） is a joint project within the framework of the Fusion Materials Implementing Agreement of the International Energy Agency （IEA）. Shielding is one of the key issues of the IFMIF engineering design. Due to the complex geometry and large size of the shields, it is difficult to make accurate shielding design using the conventional computational tools. To handle this problem, a coupled 3-D computational scheme has been developed under the cooperation of the Institute of Plasma Physics of Chinese Academy of Sciences and Forschungszentrum Karlsruhe Germany. This paper presents the newly-developed 3-D coupled computational scheme and its application to the IFMIF shielding design.
