The paper deals with a system of equations that describes steady-state process of radiative-conductive heat transfer in a bounded domain with boundary conditions of specular and diffuse reflection of radiation and boundary conditions of the third kind for temperature. For the description of radiative energy field, the $SP_3$ approximation of the simplified spherical harmonics method is used. We establish properties of existence and uniqueness of the solution of the boundary value problem under constraints on coefficients in boundary conditions which are fulfilled over entire range of feasible physical data.
Keywords: radiative heat transfer, $SP_3$ approximation, $SP_N$ approximation, unique solvability.
