Description
Feeders, as key components located on the upper and bottom of ITER tokomak, provide power supply, cooling and signal measurement to ITER superconductive magnets (PF, TF and CC coils). The installation of Feeder joints consists of three major stages (joint assembly, joint insulation, mechanical installation) and hundreds of precise operations, and involves thorough planning, engineering, special process, qualification, challenging welding, etc. To date, a significant progress of ITER feeder joints installation has been made, including completion of the first CFT-CTB joint assembly, closure of the CFT-CTB connection of first superconductive joint. This paper will provide a brief overview of the recent progress of Feeder joint assembly, as well as some critical process, challenges and lesson learned in construction.
