COUPLED ELECTROMAGNETIC AND THERMOHYDRAULIC ANALYSIS OF THE ITER CABLE JOINT

An analysis of the current distribution in a joint of International To kamilk ITER has been carried out using two separated models (3D static transport current model and 3D thin conducting shell mode) for eddy c urrent). The calculations mere made by two finite element packages KOM POT/C and TYPHOON. The total resistance of tile joint and the total Jo ule loss created by the transport current and induced currents due to the external magnetic field change were estimated. Different modes, of ITER operation were considered, Thermohydraulic response of the cooli ng system on transient and steady state disturbances in the joint were modeled by the VINCENTA code, which allows to define the transient te mperature behavior of the joint assembly materials and Cable-In-Condui t Conductor (CICC) cooled by supercritical helium which flows in therm ally and hydraulically coupled channels.
