      The formulation of 1-D boundary-value problems in radiation gas dynamics approximated with radiant heat conduction equations for heterogeneous media is considered. A calculation method based on the gas dynamics approximation with the "Crest" scheme is briefly described. The heat transfer is computed using a purely implicit difference scheme. The package structure and its principal capabilities are given.

      A method is developed to solve a 2-D nonstat ionary kinetic radiation transport equation in a nonhomo- geneous region being a rotational body. The method takes into account isotropic radiation scattering and absorption and also material equilibrium radiation. The radiation entering a region through its boundary surface is assumed to be Lambert-distributed. A system of source equations is given. The computational scheme derivation is described and its major features are presented.
