文摘A process named gel-casting has been developed for the production of dense UO2 kernels for the high-temperature gas-cooled reactor.Compared with the sol-gel process,the green microspheres can be got by dispersing the U3O8 slurry in gelcasting process,which means that gelcasting is a more facilitative process with less waste in fabricating UO2 kernels.The UO2 kernels with the size of 500 μm,O/U≤2.01,density of 10.70 g·cm-3 were obtained by gel-casting process followed by heat treatment.
