Mixed material cells have long posed challenges for radiation hydrodynamic treatments in multi-physics codes. Baer and Nunziato developed a two-phase mixture formulation which is recently expanded by Baer and Schumacher to a generalized model. We present an extension to this generalized continuum mixture theory by this model incorporating energy-based gray radiation diffusion in a multi-component fluid. The extended model is presented along with a numerical approach including verification examples.
