Abstract

In the field of Tokamak fusion devices, a critical engineering design issue is related to the complete knowledge of the electromagnetic transient phenomena induced by a disruption event (rapid quenching of the plasma current). This work concerns the specific use of the 3D general purpose eddy-current code TRIFOU, based on a mixed FEM and BIEM technique and using the magnetic field as a state variable. The main objectives are to estimate the circulation of Foucault induced currents and to calculate the distribution of Laplace body forces generated from the coupling of the eddy-currents with the magnetic fields. The application is dedicated to the inboard First Wall component designed for the ITER (International Thermonuclear Experimental Reactor) machine.
