Magnetic damping effects in fusion reactor first wall

DOI

Description

This paper describes numerical simulation of magneto-structural coupled vibration of a fusion reactor first wall. A numerical code was developed based on FEM. Current vector potential method based on thin plate approximation was applied to the electromagnetic field calculation including electromotive force by velocity. The code was applied to the ITER first wall. Numerical results show that flexible thin structure is preferably applicable to the first wall and other structural components.
