During the fabrication and / or irradiation of the
dispersion fuel elements, the fuel particles react with the surrounding Al
matrix. This reaction results in the formation of a
zone consisting of intermetallic compounds. The low thermal conductivity of these compounds
has a major effect on the fuel temperature as well as on the swelling of the
between U-Mo /Al is being investigated using chemical
diffusion couples. In this paper the first
results obtained with optical and scanning electron microscope, electron
microprobe and X-Ray diffraction are presented.
of the effect on the formation of the interdiffusion zone of small additions of
Mg to Al is the primary purpose of this study.
