Description
This paper presents an overview of the evolution of chemical exchange processes for uranium isotope enrichment from the early unsuccessful solvent extraction studies carried out by the Manhattan Project to the successful U(III) - U(IV), CHEMEX ('French') process and the successful development of the redox, U(IV) - U(VI), ion exchange process, ACEP, by Asahi. The Bigeleisen - Mayer theory of isotopic exchange equilibria, which provided a seminal and major role in the researches leading to practical uranium enrichment processes, is utilized to analyze elementary separation factors for uranium isotope enrichment by chemical exchange reactions. Redox processes are the only known chemical exchange processes that meet the criteria necessary for a useful separation. (author) 61 refs
