Title:
ADVANCED TRITIUM SYSTEM FOR SEPARATION OF TRITIUM FROM RADIOACTIVE WASTES AND REACTOR WATER IN LIGHT WATER SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2014/172360
Kind Code:
A3
Abstract:
Systems, methods, and processes for a high throughput, low concentration processing of low activity tritiated light water include the electrolysis of at least some of the tritiated water to produce hydrogen and tritium gas. The hydrogen and tritium gas produced by electrolysis in some cases are combined with heated water vapor to increase throughput and passed through a liquid phase catalytic exchange column, which generally includes a catalyst that includes palladium coated with a hydrophobic polymer. As the hydrogen and tritium gas, along with heated water vapor, rise through the LPCE column, the tritium is retained on the catalyst. Deionized wash water passes down the column (i.e., in the opposite direction of the flow of the hydrogen gas and heated water vapor) and carries the retained tritium out of the LPCE column.
