Recently the nonlinear characteristic scheme for spatially discretizing the discrete-ordinate equations was introduced. This scheme is accurate for both optically thin and optically thick spatial meshes and produces strictly positive angular fluxes. The nonlinear characteristic discrete-ordinate equations can be solved using the source iteration method; however, it is well known that this method converges prohibitively slowly for optically thick problems with scattering ratios at or near unity. In this paper the authors describe a diffusion accelerated solution method for solving the nonlinear characteristic equations in slab geometry.
