SILICON CARBIDE CLADDING AND BRAZING CONNECTION METHOD THEREFOR, AND FUEL ROD AND FUEL ASSEMBLY
A brazing connection method for a silicon carbide cladding, comprising the following steps: S1, using Al and Si as connection materials, providing the connection materials between a cladding pipe and an end plug which are matched with each other, forming a middle connection material of an Al/Si/Al three-layer structure, and forming, by means of the middle connection material, the cladding pipe, and the end plug, an assembly to be connected; and S2, placing said assembly in a vacuum or inert atmosphere for brazing connection, the middle connection material forming a connection layer, and connecting the cladding pipe and the end plug into a whole. The present invention further relates to a silicon carbide cladding formed by the method, a fuel rod comprising same, and a fuel assembly. In the present brazing connection method, Al and Si are used as the connection materials, and the connection layer of the Al/Si/Al three-layer structure is formed between the cladding pipe and the end plug, such that high-strength and reliable connection of the SiC cladding is achieved, and the SiC cladding is good in high-temperature resistance and hydrothermal corrosion resistance, thereby meeting nuclear application requirements.
