Design and Production of industrial systems
End of 2018, CNIM has been untrusted with installing the two Sector Sub-Assembly Tools (SSAT), key tools for the construction of ITER reactor (as they will assembly the sectors of the vacuum chamber), with unparalleled adjustment performance (moving twice 400 tons to the nearest millimeter).

The SSAT assembly operation completed in June 2019, load tests can now be performed. It consists in carrying out a series of kinematic operations with two mockups, simulating the Toroidal Field Coils (superconducting magnets contributing to the confinement of the plasma inside the vacuum chamber) and positioned on both arms of each SSAT.
The complexity of the functional load tests lies in the dimension of the test models - 17 m high, 8 m wide by 8 m, their weight - 353 tons each - and the positioning to the millimeter.
Using lifting equipment supplied by ITER, as well as an 800 tons mobile crane and a 750 tons bridge, CNIM, the maneuver leader, managed the delicate operation of installing 353 tons test loads on SSAT # 1, in particular the lifting of the parts and their very precise positioning.
ITER Organization-supported load tests can now start on SSAT # 1. They will last 1 month.
Delivery of functional SSAT is scheduled for fall 2019.
