The neoclassical scaling relations satisfying kenetic requirements are derived for a mul-ticomponent plasma in an axisymmetric toroidal magnetic configuration, using a model collision-operator and the variational principle developed by Rosenbluth and Glasser. On the basis of these scaling relations, explicit expressions for the neoclassical fluxes of the multi-component system are obtained in terms of the component parameters nj,mj,Zj and Tj. Finally, the dependence of the neoclassical transport coefficients on the aspect ratio R/r is discussed in detail.
