The spherically-symmetric spectral (group) problem of heat radiation transfer and numerical solution method for the problem are formulated. The method is based on combination of the first- and second-order finite-difference approximations and on iterative amendment algorithm used to solve a set of non-linear difference equations.
      Convergence of iterations and accuracy of mesh solutions are discussed. A numerical solution of a multi-group problem is given.
