Fusion Friday (5): ITER Machine Assembly

The International Thermonuclear Experimental Reactor (ITER), when completely assembled, will have a mass of 23,000 tonnes (excluding external support equipment) with components manufactured around the world to tolerances, in some sections, in the fractions of a millimetre. Assembling all of this is an intricate three-dimensional jigsaw puzzle which has been underway since 2018. This talk describes the challenges and approaches taken to machine assembly.
