Toroidal field coils

Finishing touches on site

2 Jun 2020
Between the time a toroidal field coil is delivered to ITER and the moment it is ready to enter the pre-assembly process, certain tasks must be performed: the welds in the helium piping need to be leak-tested and additional handling and pre-assembly equipment must be added.

Delivered on 17 April, TF9 from Europe is now stored in a dedicated building, where tests are being performed and handling and pre-assembly equipment is being installed.
Two toroidal field coils, TF9 from Europe and TF12 from Japan, were recently delivered to ITER. A third coil, TF13, sailed from Kobe harbour in Japan on 15 May 2020 and is expected reach France in mid-June.

Temporarily alone in the Cryostat Workshop, TF12 from Japan was recently extracted from its transport frame.
On each component, preparatory work must be accomplished before the coils are transferred to the upending tool in the Assembly Hall to be lifted to vertical and installed on the wings of the sub-sector assembly tools.

TF13, which will be paired with TF12 in the first "pre-assembly," sailed from Kobe harbour in Japan on 15 May 2020 and is expected reach France in mid-June.
The first toroidal field coil "pair"—TF12 and TF13—will be associated with vacuum vessel sector # 6 (which Korea recently finalized) and thermal shield panels to form the first of nine "sector sub-assemblies" to be descended into the Tokamak assembly pit.
