  • Patent number: 9682860
    Abstract: Provided are processes and systems for the reclamation of tritium from a tritiated byproduct material. A liquid organic tritium containing material is subjected to a series of reactions to isolate purified tritium gas that can be used in subsequent tritiation reactions. The processes involve in some aspects a semi-automated system that subjects a byproduct liquid organic tritium containing material to an oxidation to produce tritiated water, a chemical splitting of the tritiated water to form a tritiated gas that is substantially free of oxygen or other contaminants, and the isolation of purified tritium gas from hydrogen containing HT gas. The processes and systems provided substantially reduce both the cost to produce tritium source material for labeling of organic molecules and the amount of byproduct that requires disposal.
