The quasilinear Fokker–Planck formulation is generalized for lower‐hybrid current drive to include the wave‐induced radial transport of fast electrons. Toroidal ray tracing shows that the wave fields in the plasma develop a large poloidal component associated with the upshift in k and the filling of the ‘‘spectral gap.’’ These fields lead to an enhanced radial E×B drift of resonant electrons. Two types of radial flows are obtained: an outward convective flow driven by the asymmetry in the poloidal wave spectrum, and a diffusive flow proportional to the width of the poloidal spectrum. Numerical results relevant to Alcator C [Phys. Rev. Lett. 53, 450 (1984)] and JT‐60 [Nucl. Fusion 29, 1815 (1989)] are presented; they show that the radial convection velocity has a broad maximum of nearly 1 m/sec and is independent of the amplitude of fields. In both cases, the radial diffusion is found to be highly localized near the magnetic axis. For JT‐60, the peak of the diffusion profile can be quite large, nearly 1 m2/sec.
