Electromagnetic transients induced in the tokamak first wall by a plasma disruption using 'TRIFOU'

A complete 3-D electromagnetic analysis of the inboard first wall of the ITER fusion device has been performed using the 3-D general-purpose eddy-current code TRIFOU, based on a mixed FEM (finite element method) and BIEM (boundary integral equation method) technique and using the magnetic field as a state variable. The main objectives were to estimate the circulation of induced currents and to calculate the distribution of body forces from the coupling of eddy-currents and magnetic fields. The use of TRIFOU has demonstrated that eddy currents and Laplace body forces in complex 3-D situations can be predicted accurately.<
