Progress on R&D and design work for the ITER toroidal field coils

The European Participant Team of ITER has assessed and validated the design and manufacturing of the ITER toroidal field (TF) coils with the production and test of one model coil, the toroidal field model coil (TFMC), and the fabrication of three full scale sections of the TF coil cases. A vast campaign of development and qualification of strands, cables, joints, insulation systems and structural materials has also been carried out. The R&D work has validated the choice of the superconducting strands and structural materials, as well as the manufacturing techniques and procedures for the winding, electrical joints and cases. The main goal of this paper is to highlight the impact of the European R&D results on the design of the ITER TF coil.
