General address of the contracting authority (URL):


The ITER Tokamak requires a superconducting magnet system, which consists of four main sub-systems: the 18 Toroidal Field coils (TF coils), the Central Solenoid (CS), the 6 Poloidal Field coils (PF coils) and the Correction Coils (CC coils).

The TF conductor is a Cable-In-Conduit Conductor (CICC) and relies on twisted, multifilament Nb3Sn-based composite strands that are Chromium plated. The un-reacted strands are cabled and the cable is jacketed into thin tubes to become a CICC. After compaction the conductors are heat-treated to temperatures up to 650 ̊C.

The PF conductor is also a CICC but made of twisted NbTi strands that are Ni plated. After cabling of the strands the cable is jacketed into a thick round-in-square jacket and compacted to final dimensions. The JT-60SA TF conductor is made of NbTi strand and is also a Cable in Conduit Conductor. The JT-60SA TF jacket is a thin stainless steel rectangular tube.

The scope of the contract is the acquisition of the following supplies: TF and PF conductors in conformity with the terms provided in the Tender Specifications: 20 km of TF; 28 km of JT-60SA TF; 22 km of PF (PF1 and PF 6).
