Erosion/redeposition is examined for the sidewalls of a dissipative divertor using coupled impurity transport, charge exchange, and sputtering codes, applied to plasma solutions for the ITER design. A key issue for this regime is possible runaway self-sputtering, due to the effect of a low boundary density and nearly parallel field geometry on redeposition parameters. Net erosion rates, assuming finite self-sputtering, vary with wall location, boundary conditions, and plasma solution, and are roughly of the following order. 200–2000 Å/s for beryllium, 10–100 Å/s for vanadium, and 0.3–3 Å/s for tungsten.
