“…If tritium is not removed from the fuel (e.g. 3 by the Voloxidation Process) before dissolution in aqueous acid (an early step in Purex reprocessing flow sheets), a major portion of the tritium formed by ternary fission in light water reactors is expected to appear in the low~level aqueous waste (LLAW) stream of the plants r~processing the spent fuel from LWRs. Presently accepted schemes for managing this waste stream include dispersal as a vapor to the atmosphere or as a liquid to surface streams; this waste stream is diluted with air or water to concentrations less than those specified by radiation concentration guid~lines.…”

A pressure-reducing method is used effectively in a water distillation process to enhance the equilibrium separation factor. The feasibility of the technique is established through application to a water-hydrogen chemical exchange process using a prototype separation column. Isotope separation experiments examining the water-hydrogen chemical exchange reaction are performed for column pressures of 12-101 kPa, and the separation factors for hydrogen and deuterium are obtained. The HETP (Height Equivalent to a Theoretical Plate) values were distributed in the range of 6 to 15 cm. By reducing the pressure in the column, the process temperature can be lowered without reducing the molar fraction of water vapor in the gas stream. It confirmed that the separation factors under reduced pressure are larger than under atmospheric pressure. This fact demonstrates the effectiveness of reduced pressure in water-hydrogen chemical exchange processes.
