Abstract

The eddy current induced in first wall components of a fusion reactor is investigated numerically and experimentally to clarify effects of electromagnetic force on structures branched and with a hole. The eddy current is analyzed by using the current vector potential method T-method) with an application of the finite element method. Partial torus modules of the first wall scaled about 1 20 are made of stainless steel for measurements of the eddy current. The plasma current as a source of the eddy current is simulated by a pulse current from a 16 times turned circular coil. The discharging peak current is 246 kA turns with a period of 1.4 ms and the eddy current is measured with the differential pick-up coil method. Fairly good agreement of numerical and experimental analyses results in validations of both the computational code and the measurement methods. The Lorentz force of the first wall module is also analyzed by the code for an evaluation of the transient electromagnetic force.
