ABSTRACT:
A flow of hydrogen and steam is first passed into isotope exchange with fresh water of natural deuterium concentration to effect enrichment of the hydrogen with deuterium. Thereafter, the enriched hydrogen and steam mixture is heated to superheat the steam and the mixture is passed into a reactor and over a suitable catalyst to effect a further isotope exchange. The hydrogen is thus further enriched with deuterium from the superheated steam. The further enriched hydrogen is then delivered to a heavy water recovery plant.
