Abstract
Previously known extraction columns for fissionable material (nuclear fuel) and breeder material in the reprocessing of spent fuel elements with pulsation mechanisms working by air impulses, drag along the radioactive aerosols. These difficulties are avoided with the extraction column of the invention in which the column body contains a central tube filled with extraction agent which is connected with a pulsating pump via a multiple part sealing liquid container with the parts joined together according to the principle of communicating tubes.
