      SVET technique is proposed for solving heat radiation transfer problems. The technique involves the characteristics method, supplemented with "balancing", considerably improving properties of the difference scheme and allowing computations to be run with energy balancing up to fractions of a per cent. The technique is extended to spectral case, the maximum-minimum principle allowing for scattering being proved for it. The technique proposed is efficient in solving problems of heat radiation propagation without regard to movement in media of low matter density and strong dependence of temperature and radiation intensity on time. It is of satisfactory accuracy, allows easy solution of problem of organizing iterations between energy and nonstationary radiation transfer equations.
