DEVELOPMENT OF IRON CORE MODELS IN DINA CODE FOR DETERMINATION OF TOKAMAK PLASMA EQUILIBRIUM.
Problem definition of iron core taking into account for free boundary tokamak plasma equilibrium modeling in axisymmetrical approximation together with diffusion of poloidal magnetic flux, energy and particles in frame of DINA code is presented. Results of plasma current ramp-up modeling are shown for T-15 tokamak, which is modernized to be able to obtain the divertor magnetic configuration.
