Installation, commissioning and acceptance tests of the Switching Network Units for the central solenoids of JT-60SA

JT-60SA is an international tokamak being built in Naka (Japan) as a joint collaboration between Europe and Japan for the applied researches on the use of nuclear fusion as a new energy source. The procurement of the different systems composing JT-60SA is managed as in-kind contribution shared between European and Japanese institutions. The procurement of the Switching Network Units (SNUs) for the Central Solenoid (CS) is supported by Europe. After a four-year design and manufacturing in Europe, the JT-60SA CS SNUs and the related components were delivered to Japan in October 2016. This paper describes the activities for the on-site installation, commissioning and tests of this procurement.
