摘要:ITER(国际热核聚变实验堆)真空室中子屏蔽主要是屏蔽中子流、伽马射线以及降低环
向场波纹度。根据 ITER 真空室内屏蔽结构的特点,基于单元化的初期概念设计,对中子屏
蔽进行了空间结构布局,提出了中子屏蔽组件的设计模型。利用 CATIA 软件,通过骨架驱
动方法与参数化技术完成了屏蔽组件的实体建模与装配。该设计方法有别于传统的设计方
法,对于复杂模型的建模,缩短了设计周期,提高了设计效率。为中子屏蔽结构的虚拟分析
与修改,提供了便利。

Abstract: Neutron shielding structure of the ITER vacuum vessel will be applied to shielding
neutron and gamma ray reducing the toroidal field to in-wall shielding structural
features of ITER (International Thermonuclear Experimental Reactor) vacuum vessel and based
on the concept design of shielding block, the neutron shielding structure was done pace layout and
design model was applied. By using CATIA software, the skeleton drive method and parametric
technology parametric design, preliminary solid models of the shielding units and the assembly
simulation process were finished. This design method is different from traditional design methods
