Abstract: The fluidized bed applications involved in all processes of the uranium fuel industry，including uranium ore leaching，the uranium chemical conversion，enrichment of uranium isotopes，fabrication process of fuel elements of water reactors and high temperature gas cooled reactors，spent fuel reprocessing，nuclear fuel industrial waste treatment，as well as the fluidized bed nuclear reactor design process，were introduced and reviewed. A variety of fluidized bed type，structure，and the advantages and disadvantages were summarized，the specific design processes of the fluidized bed were also included in this paper. The extensive applications of the fluidized bed in the uranium fuel industry and possible development area in the future were proposed. This paper is helpful in the development of better study on the scope and basis of the fluidized bed technology applications in the industry，and provides references to the interdisciplinary research in the uranium fuel industry.
