Abstract
The existing literature on UAl2-Al dispersions is surveyed and a comparison with similar data for UAl3-Al dispersions is attempted. The experimental work included the preparation of a practically single-phase UAl2 compound by induction-melting and its grinding to a predetermined particle size. The blending of UAl2 and aluminium powders into suitable dispersions and their compaction by cold pressing to the densities required for roll-bonding are described. The picture-frame technique was used to clad the dispersions with aluminium to produce test-plates for irradiation experiments.
The kinetics of the UAl2 and UAl3 solid-state reactions with aluminium are dealt with on a qualitative basis. Throughout, comparison is made with the known technology of UAl3-Al dispersions, taking into consideration uranium densities, production aspects, pyrophoricity, volume changes, &c.
It is concluded that UAl2-Al dispersions have potential applications as fuels for advanced test reactors.
