Caracciolo, V. P.

Sufficient data were obtained with a semiworks-scale dissolver to permit design of plant-scale equipment for the dejacketing and subsequent dissolving of aluminumclad uranium fuel elements of various shapes and sizes. The aluminum dejacketing reaction occurred as fast as caustic was added and was independent of the shape of the elements. The rate of uranium dissolving increased with increasing acidity, was proportional to the exposed surface areas and was independent of the shape of the elements. A mechanism for uranium dissolution is discussed that explains the variation of acid consumption and the rate of gas evolution. (auth)
