Recovery of Terminations in ITER CS Module 3

The ITER Central Solenoid (CS) is under fabrication by the US ITER organization and its subcontractors. All CS modules (CSM) were or will be tested at 40 kA in the Final Test facility at General Atomics. CSM 3 testing campaign took place in 2021, and a breakdown occurred that damaged the terminations of the module. To recover, new terminations needed to be designed, qualified and built to make the CSM3 fit for service. This effort had several challenges that were not addressed in the previous projects with large Nb3Sn magnets with cable-in-conduit conductors. This paper describes a design, fabrication and qualification of the terminations.
