In ITER the main loss mechanism of fast fusion alpha particles is expected to be due to toroidal field (TF) ripples caused by the finite number of TF coils. The associated radial diffusion of fast alphas is specified by an energy and space dependent diffusion coefficient which can be extended to account also for toroidal Alfven eigenmode (TAE) diffusion. Energy transfer from the fast alphas to the thermal background plasma is considered to occur due to Coulomb collisions and nuclear elastic scattering (NES). The α-transport is described here by a reduced slowing down kinetic equation of which the numerical solution provides for the energy-, space- and time-dependent alpha particle distribution in the tokamak plasma. This alpha distribution then constitutes the basis for a determinative calculation of the actual fusion power allocation to each distinct background species. Though TAE diffusion alone is not a significant fusion power loss mechanism, our recent calculations indicate that the coaction of TF-ripple (TFR) and TAE transport processes synergisticly results in a substantial reduction of fusion alpha power deposition.
