TRANSIENT ELECTROMAGNETIC ANALYSIS IN TOKAMAKS USING TYPHOON CODE

The transient electromagnetic analysis of conducting structures in tok amaks is presented. This analysis is based on a three-dimensional thin conducting shell model. The finite element method has been used to so lve the corresponding integrodifferential equation. The code TYPHOON h as been developed to calculate transient processes in tokamaks. Calcul ation tests and the code verification have been carried out. The calcu lation results of eddy current and force distribution and a.c. losses for different construction elements for both ITER and TEXTOR tokamaks magnetic systems are presented.
