Starting EU Production of Strand and Conductor for JT-60SA Toroidal Field Coils

Included in the Broader Approach (BA) treaty, the JT-60SA project foresees to upgrade the existing JT-60U tokamak by substituting superconducting magnets to the present resistive magnets system. For this, a bilateral EU-JA procurement agreement drives EU, represented by Fusion for Energy (F4E) entity, to procure in-kind the totality of the 18 JT-60SA Toroidal Field (TF) Coils. Being almost the totality of the in-kind procurement of F4E for JT-60SA, the TF conductor manufacture monitoring is directly held by F4E, finalized by a delivery of components to collaborative EU institutes (CEA and ENEA) for its transformation into TF coils [1]. The organization of TF conductor procurement lies on two con- tract placed in December 2010 by F4E to industrial operators for strand manufacture on one side and cabling - jacketing transformation on the other side. After a general overview the present paper describes the different steps reached up to the present state of fabrication achievement. The status of the ongoing manufacture and the foreseen next steps targeted in the near future will also be mentioned.
