With the completion of commissioning, these giant tools are now cleared for operation in 2020, when the first 440-tonne vacuum vessel sectors will be delivered to ITER. The tools will suspend the sectors vertically in their centre while they are pre-assembled with toroidal field coils and thermal shield panels prior to transport to the assembly pit.
The 360-tonne megalith is lowered to the Assembly Hall floor. After six months hooked up first to one, then the other, of the sector sub-assembly tools (left), the test loads will be stored in laydown areas until called for use to commission the upending tool.
With testing completed, the test loads have now been removed from the tools and transferred to a laydown area. They will be used again in the months to come—this time to test the
Tool commissioning is an important activity, during which the all specified functional requirements are demonstrated. Also, for tools sourced outside of the European Union, it is the occasion to show compliance with EU regulations.
