A comparative analysis of the role of various ripple-induced classical transport processes of high-energy alpha particles in International Thermonuclear Experimental Reactor (ITER)-like tokamaks is presented. It is shown that alpha particles escape from a plasma mainly because of collisional, rather than stochastic, diffusion. The poloidal distribution of the alpha wall load in ITER is determined.
