<p>T I T L E PROCESS FOR THE EXTRACTION OF TRITIUM FROM A LIQUID HEAVY WATER STREAM I N V E N T O R Allan H. Dombra A process for the extraction of protium and tritium from a liquid heavy water stream comprising contacting the liquid heavy water with a countercurrent gaseous deuterium stream in a column packed with a catalyst such that tritium is transferred by isotopic exchange from the liquid heavy water stream to the gaseous deuterium stream, passing the gas enriched in tritium from the column through means for removing tritium therefrom and returning the gas lean in tritium to the column, taking a portion. of the liquid heavy water stream after it leaves the column and passing it through an electrolysis stage to produce a gaseous deuterium output which is returned to the column and a gaseous oxygen output that is sent to waste or to other uses, obtaining the remaining fraction of the liquid heavy water output from the column, said heavy water being reduced in tritium content.</p> |
