ABSTRACT
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 fuel.
Interdiffusion 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.
Investigation of the effect on the formation of the interdiffusion zone of small additions of Mg to Al is the primary purpose of this study.
