<p>The uranium content of an alloy of aluminium and uranium is increased by heating the alloy with a metal halide in order to volatilize aluminium halide. The alloy may be heated stepwise to 1000 DEG C. or more with zinc chloride, preferably under vacuum, aluminium chloride being volatilized. Alternatively the alloy may be heated to 800 DEG -1000 DEG C. under vacuum with aluminium fluoride (cryolite) in which case aluminium monofluoride volatilizes. The process may be used to regenerate nuclear fuel element, fission products being removed at the same time (see Group XL(a)).</p> |
