Deposition of ZrC coats on UO2 particles using the chloride process

Zirconium carbide is the most probable candidate for the replacement of silicon carbide as a force layer in the advanced TRISO fuel particles. To come to such decision in practice first of all it is necessary
• to determine the conditions of ZrC deposition on fuel kernels;
• to assess its viability as a fuel coating before and after irradiation including interactions between ZrC and key fission products.The main goal of the present study is to investigate influence of conditions of zirconium carbide deposition on uranium dioxide kernel in a fluidized bed on composition of coats and some their characteristics. Results of such investigations are given.
