Uranium enrichment device

A device for enriching uranium by the separating-nozzle process, is claimed. It inlcudes a plurality of separating-element units; a plurality of heat-exchangers including tubes and constructed as coolers positioned upstream of the separating-element units; a corresponding number of associated compressors; and gas ducts for supplying the starting gas and for incorporating the separating-element units into cascades during operation. The individual separating-element units and heat exchangers form individual components of a cascade stage, each component being disposed in a compartment of a vessel having a substantially circular cross-section. The compressors are removably mounted under the vessel. The vessel is horizontally disposed on supports and the compartments are formed by diametrical partitions in the vessels. The heat exchangers have tubes which extend through the compartments and diametrical partitions. The device further includes a distribution chamber connected upstream and a header connected downstream of the vessel
