Abstract:

Based on port C of ITER machine, design of Chinese helium-cooled ceramics breeder test blanket module (CH HCCB TBM) is updated and its main properties and design parameters are given by comprehensive analyses including neutronics optimization, structure mechanics analyses, thermo-hydraulics and thermo-mechanics analyses, flowing analyses, electromagneticanalyses and fabrication consideration. Chinese updated TBM is designed with 484mm in toroid, 1660mm in longitude and 675mm in poloidal. According to this design, fabrication processes such as vacuum diffusion welding and vacuum electron-beam welding on new material CLF-1 being developed are studied. Fabrication procedures for key components such as first wall etc. are explored. Mockups for first wall and submodules’ cooling plates have been trial-produced.

Key words: TBM, Modified design, Critical processes

摘要：

基于ITER装置窗口C，完成了中国氦冷固态增殖剂试验包层模块的设计改进，给出了模块主要性能参数和设计参数。改进后的TBM包层模块外围尺寸为环向484mm、纵向1660mm和极向675mm。根据该模块设计的结构特点，对研制用材料CLF-1钢真空扩散连接和真空电子束焊等关键工艺进行了研究，初步探索了第一壁等关键部件的研制工艺流程，并最终成功试制了第一壁和子模块冷却板模拟件。
