Abstract：
 This invention involves a preparation of UO2 fuel ceramic microspheres method, belongs to nuclear material technology. First mix organic monomer with water to prepare premixed liquid, and then make some solid content of the stable slurry through vibration become droplets, decentralized to a certain temperature oily medium, can also add catalysts N, N, N ', N'- tetramethyl ethylenediamine into oily medium. Small drop under the interfacial tension change into ball; the droplet internal polymer monomer carry out polymerization, thereby solidif to ball. Then after washing, drying, roasting and sintering process and ultimately achieve high yields and with the design requirements of UO2 fuel ceramic microspheres. Because in this method slurry contains less organic matter, so skim is easy, and reduce the tendency of crack when microspheres drying and calcination, thus eliminating the need of nitrate dissolving U3O8 powder and plastic cooking processes.
