ABSTRACT

This paper presents the development of theoretical model for the purpose to calculate and analyze halo and eddy current effects in the tungsten divertor of Tokamak (Fusion) reactor. In the first step, focal points for plasma energy, sideways forces (on the vessel), impurities, and halo–eddy current effects (in terms of poloidal and toroidal magnetic field orientations) were calculated. During the verge of point calculation, the research was extended to calculate the initial conducting point (halo current) for the tungsten divertor plate. Three cases were considered for investigating the plasma energy during upward and downward flows to the divertor plate. Poloidal and toroidal orientation of plasma energy were investigated and the theoretical model was developed. Initial conducting point with respect to (r,z) was calculated for halo current calculations and its derivatives. A mechanism for the development of the asymmetry and for estimating electromechanical loads was performed. For computational analysis, a Matlab program was developed to calculate and verify halo current and plasma energy calculation points. The main objective of the research is to develop a theoretical-computational model to evaluate plasma behavior and divertor system in any Tokamak reactor.
