Magnetic field perturbation and magnetic stress analysis due to a ferromagnetic first wall

Based on a magnetization integral equation, a magnetic field analysis method was developed for 3-D complicated components formed by thin shells. The agreement between numerical results and experimental ones was good, confirming the validity of this method. The method was applied to the analysis of magnetic induction and stress in a ferromagnetic first wall for a tokamak power reactor. It was found that the wall could be used in a fusion reactor without much problem.<
