      The difference scheme KREST (cross) has been developed for the numerical solution of the nonstationary spectral radiation transport equation and energy balance equation in a 3D geometry. An approach to approximating boundary conditions has been suggested. The scheme stability in energy norm has been analyzed. The Kellogg lemma has been generalized for the estimation of the transition operator norm. The calculated results are presented for a model problem having exact solution.
