Engineering integrator — ITER poloidal field coils PF2, PF3, PF4, PF5 and PF6

The European Joint Undertaking for ITER and the Development of Fusion Energy ('Fusion for Energy')

The engineering integrator shall provide the engineering integration services for the supply of the poloidal field coils (PF2 to PF6 coils) as described in Section 2 of the technical specifications.
The coils are wound adjacent to the ITER site in a dedicated PF coil fabrication building and handed over to F4E for cold testing and assembly in the ITER machine. Cold testing is considered to be the final acceptance test before handing over the coils to the ITER organisation for final assembly in the tokamak hall.
The PF magnet system is composed of 6 circular coils, the winding packs (WPs) consisting of a stack of double pancakes (DPs). The PF3, PF4, and PF5 coils consist of 8 DPs, whereas PF2 and PF6 consist of 6 and 9 DPs respectively.
The coils are composed of stacks of double pancakes (DPs). Each DP is wound with two-in-hand CICC and consists of an upper and lower pancake. Each continuous section of CICC used in the two-in-hand winding is referred to as a unit length (UL). Because of the two-in-hand winding, there are 2 ULs per DP.
The two-in-hand winding scheme and stacking of DPs allows for all joints to be located at the coil outer diameter, about 15 cm away from the winding pack. The winding pack current terminals are located at the outer diameter of the coil, where the CICC has its minimum bending radius of 500 mm. Given the two-in-hand winding, there is a joint between the 2 conductors within a DP (internal joint or PJ joints), as well as joints between adjacent DPs (external joints or DPJ). Having all joints on the outer diameter allows for the ability to bypass a double pancake in the event of a short by opening 3 joints and reconnecting 2 of them.
The ULs are delivered to the coil supplier for coil winding and fabrication. After reception at the PF coil fabrication building, the conductor ULs are bent to the coil radius, insulated, and wound into the final coil dimensions using appropriate tooling. The DPs are impregnated, stacked together and the outer joints are completed. The stack is then wrapped in a layer of ground insulation and impregnated in a mould to complete the WP. After completion of the winding pack all support clamps, cover plates, jumpers, cooling pipes and instrumentation systems will be installed and the coil prepared for cold testing.
