Description
The plasma confinement of the International Tokamak Experimental Rector (ITER) is provided by the magnetic field generated by 18 toroidal filed coils (TFC). Fusion for Energy, the European Domestic Agency for ITER, is responsible for the supply of 10 TFC to ITER project.
Their procurement has been divided in three main work packages: I) the production of the radial plates, structural stainless steel components housing the Nb3Sn conductors, II) the manufacture of 10 Winding Packs (WP) and III) the cold test of 10 WP plus their insertion into the Coil Cases (CC).
This article gives an update of the status of the production of third and last work package performed under the framework of a F4E contract assigned to SIMIC SpA, an Italian company.
In particular the details of the WP thermal cycle, the insertion of the firsts TF coil in their coil cases, the closure weld, the gap filling and the machining strategy adopted to optimize the final TF coil shape optimized to minimize the field errors are presented.
