Development of ITER sector sub-assembly procedure and assembly tools

The sub-assembly strategy and tools for the complete 40° sector assembly have been developed to meet technical and functional requirements. Based on the concept of sub-assembly procedure and tools provided from ITER organization (IO), detailed procedure and relevant tools are developed by Korea domestic agency (KODA). Tools described in this paper contain upending tool, lifting tool, sector sub-assembly tool, radial beam with align units and mid-plane bracing tools. To verify the 6 degrees of freedom system for fine alignment of components, scaled-down mock -up has been manufactured and tested. This paper presents the overall 40° sector sub-assembly procedure, fundamental specifications of the relevant assembly tools and the current status of the mock-up developments.
