Non-linear saturation of the toroidal Alfvén eigenmodes (TAE) and of the resistive periodic shear Alfvén eigenmodes (RPSAE) due to magnetohydrodynamic (MHD) non-linearities is investigated numerically. The numerical code uses the reduced MHD model expanded to the third order in the inverse ratio parameter epsilon. Model equations are presented and the numerical simulations and results of non-linear simulations show the non-linear MHD saturation of TAEs and RPSAEs.
