The development of a diffusion-accelerated Sn transport method for the solution of temperature-coupled radiation flow problems on a spatial mesh of arbitrary quadrilaterals in r-z geometry is presented. The diffusion acceleration equation is derived from the diamond-like transport spatial discretization. The effectiveness of the method is shown on an example calculation and computation times are indicated.
