Abstract

The Japan Domestic Agency (JADA) for ITER will procure toroidal field (TF) coil structures and winding packs and assemble them into a final TF coil configuration. Because the manufacturing schedule of the TF coils is a critical path toward the first plasma of ITER, coil manufacturing must be successful and proceed on schedule. Therefore, risk assessment and management for its manufacturing are essential. JADA performed a risk assessment on the basis of past manufacturing experiences and a risk mitigation policy for ITER-TF coil manufacturing. The results show that risks can be mitigated to a level that we can assure sufficient quality of the TF coil by sound design, manufacturing, and quality management processes that are developed through R&D activities and the use of prototypes.
