摘要
ITER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。介绍了ITER真空室的结构特点及屏蔽结构料材的选取情况,发展了屏蔽设计思想及相关的支撑结构,对铁磁性材料填充区域进行了布局设计。依据ITER真空室物理学计算结果,确定了屏蔽区域屏蔽材料的填充率。基于三维建模软件进行了屏蔽块零件库的仿真设计和屏蔽结构的模拟仿真。
Neutron shielding structure of the ITER vacuum vessel (VV) will be applied to shielding neutron and gamma-ray and reducing the toroidal field ripple. The features of ITER vacuum vessel and the material selection for shielding structures are briefly discussed. A shielding conceptual design and some correlative support structures have been developed. The layout of ferromagnetic inserts was performed. Filling ratios of shielding materials between VV shells were acquired according to ITER W physics calculation results. In term of the ITER VV design criteria, the detailed design work for library of the shielding blocks and the emulational structure have been finished based on the 3D modeling software.
