Title: Method and apparatus for separation of heavy and tritiated water

Abstract: The present invention is a bi-thermal membrane process for separating andrecovering hydrogen isotopes from a fluid containing hydrogen isotopes,such as water and hydrogen gas. The process in accordance with the presentinvention provides counter-current cold and hot streams of the fluidseparated with a thermally insulating and chemically transparent protonexchange membrane (PEM). The two streams exchange hydrogen isotopesthrough the membrane: the heavier isotopes migrate into the cold stream,while the lighter isotopes migrate into the hot stream. The heavy andlight isotopes are continuously withdrawn from the cold and hot streamsrespectively.
