Here, both an analytic model and the toroidal MARS-F code have been employed to study the effect of the anisotropic thermal transport on the stability of the resistive wall mode (RWM) in resistive tokamak plasmas. The results show that thermal transport destabilizes the resistive plasma RWM, by effectively eliminating the Glasser-Greene-Johnson favorable average curvature stabilization associated with the resistive layer. Modification of the mode eigenfunction is also observed in MARS-F computations, due to the presence of the anisotropic thermal transport.
