The International Thermanuclear Experimental Reactor (ITER) tokamak device is composed of 9 vacuum vessel (VV)/toroidal field coils (TFCs)/vacuum vessel thermal shields (VVTS) 40 degrees sectors. Each VV/TFCs/VVTS 40 degrees sector is made up of one 40 degrees VV, two 20 degrees TFCs and associated VVTS segments. The 40 degrees sectors are sub-assembled at assembly hall respectively and then nine 40 degrees sectors sub-assembled at assembly hall are finally assembled at tokamak in-pit hall.
The assembly strategy and tools for the 40 degrees sector sub-assembly and final assembly should be developed to satisfy the basic assembly requirements of the ITER tokamak device. Accordingly, the purpose-built assembly tools should be designed and manufactured considering assembly plan, available space, cost, safety, easy operation, efficient maintenance, and so on. The 40 degrees sector assembly tools are classified into 2 groups. One group is the sub-assembly tools including upending tool, lifting tool, sub-assembly tool, VV supports and bracing tools used at assembly hall and the other group is the in-pit assembly tools including lifting tool, central column, radial beams and their supports.
This paper describes the current status of the assembly strategy and major tools for the VV/TFCs/VVTS 40 degrees sector assembly at in-pit hall and assembly hall. The conceptual design of the major assembly tools and assembly process at assembly hall and tokamak in-pit hall are presented also.
