Design of the ITER Tokamak assembly tools

ITER (International Thermonuclear Experimental Reactor) Procurement allocation among the seven Parties, EU, JA, CN, IN, KO, RF and US have been decided in Dec. 2005. ITER Tokamak assembly tools is one of the nine components allocated to Korea for the construction of the ITER. Assembly tools except measurement and common tools are supplied to assemble the ITER Tokamak and classified into 9 groups according to components to be assembled. Among the 9 groups of assembly tools, large-sized Sector Sub-assembly Tools and Sector Assembly Tools are used at the first stage of ITER Tokamak construction and need to be designed earlier than seven other assembly tools. ITER proposed Korea to accomplish ITA (ITER Task Agreement) on detailed design, manufacturing feasibility and engineering design specification of large-sized tools such as Sector Sub-assembly Tools and Sector Assembly Tools in Jan. 2007. Based on the concept design by ITER, Korea carries out ITA on detailed design of large-sized Sector Sub-assembly and Sector Assembly Tools until Sep. 2007. The Sector Sub-assembly Tools mainly consist of the Upending, Lifting, Vacuum Vessel Support and Bracing, and Sector Sub-assembly Tool. The Sector Assembly Tools mainly consist of the Toroidal Field (TF) Gravity Support Assembly, Sector In-pit Assembly, TF Coil Assembly, Vacuum Vessel (VV) Welding Tool. The design of Sector Sub-assembly Tools and Sector Assembly Tools are described herein. (orig.)
