Open the CIPO recordAbstract From the Canadian patent
The invention provides a new high temperature isotopic exchange fuel processing loop for tritium recovery in which tritium is exchanged out of impurities such as tritiated ammonia, methane and water by swamping with Ha and isotopically equilibrating the mixture in a high temperature reactor. Downstream of the reactor is a Pd/Ag permeator for separation of the hydrogen from the impurities, the separated hydrogen being sent to an isotope separation system for tritium recovery and the residual impurities being recycled. The process eliminates the need for impurity oxidation and electrolysis of DTO and does not rely on complicated catalytic decomposition reactions.

Why it's free to use
- Filed July 25, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 25, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 25, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
