The calculations for thermal conductivity of electronic origin in UN as a function of temperature are shown for nonmagnetic UN with (short, black, dashed line) and without (black solid line) correction for nonresidual resistivity. The previously estimated phonon contribution to the thermal conductivity at 1000 K [8] is indicated by a pink diamond and at lower temperatures by a pink dashed line [7] and the electron contribution at 1000 K [8] is indicated by a green square. The dotted line indicates the phonon contribution evaluated by the linear interpolation between the estimates from [7, 8]. The electronic contribution, calculated from the experimental resistivity [7], is shown by blue triangles. The measured total thermal conductivity is indicated by the long, red, dashed line [3] and black spheres [16].
