Qualification and Readiness on Feeder-Type Joint Assembly for ITER Magnet System

Feeder-type joint assembly is identified as a non-conventional process that require robust qualification not only on the process, but also on the skill of the operators so as to grant an access to construction site. The joint assembly qualification sample underwent a test program in regards to different operation conditions in various magnetic fields, currents and helium mass flows, etc. The results support the proven process of the joint assembly performed by knowledgeable personnel who service
s
the operator training and qualification. It is also aimed to report that the test performance of the qualification sample reaffirms the previous test result. Further verification on the joint characteristics was performed. The first-of-a-kind assembly on the segmented superconducting busbars is being prepared using an approach where risks are identified, assessed and prioritized. On-site assembly readiness on the busbar joint assembly process through an operator qualification program is addressed.
