Effect of core-edge coupling on operation regimes of ITER-like reactor

Abstract A model has been developed which is capable to describe in a self-consistent way plasma dynamics in the center and edge region of fusion reactor. The core plasma is treated in the frame of 1D radial transport model whereas in the edge the 2D multifluid code EPIT has been used. The EPIT code solves in the slab geometry the MHD equations for densities and velocities for all ions species as well as for electron and ion temperatures. In the paper the iteration scheme leading to steady state solution of coupled core and SOL system has been analyzed and tested numerically. The model has been used to investigate operation regimes of the ITER-FEAT tokamak.
