A numerical algorithm for solving 2D equations of heat radiation transport in multigroup kinetic approximation is studied. The algorithm is based on DDAD-scheme, which is a scheme of DSn-method with artificial dissipation. A method of diagonal matrix segregation (DMS-method) is used to accelerate iterations in solving a transport equations set. The computational data for two model problems are presented.
