A new separation method of hydrogen isotope by dynamically created nonequilibrium state.

Composition of deuterium (heavy) water in light water was drastically reduced to one-half by one stage of a newly invented device that can create a nonequilibrium vapor state driven by a dynamic system. Vapor density of heavy and light water is arbitrarily controlled. This system works at 20–60°C, even under atmospheric pressure. The mechanism should equally work even for tritium water, as tritium-contaminated water is a problem in the treatment of nuclear reactors as well as fusion reactors. [ABSTRACT FROM AUTHOR]
