CONNECTION METHOD FOR SILICON CARBIDE CLADDING FOR NUCLEAR APPLICATION, AND SILICON CARBIDE CLADDING AND APPLICATION THEREOF
Disclosed in the present invention are a connection method for a silicon carbide (SiC) cladding for nuclear application, and a SiC cladding and an application thereof. The connection method comprises the following steps: S1, preparing a connection slurry; S2, uniformly applying the connection slury on connection surfaces of a SiC end plug and/or a SiC cladding tube, and relatively matching the connection surfaces of the SiCend plug and the SiC cladding tube to form a connection structure; S3, heating the connection structure to 100-300°C in a protective atmosphere, keeping the temperature for 0.1-4 h, and curing the connection slurry between the SiC end plug and the SiC cladding tube to form a connection layer; and S4, performing resistance welding treatment on the cured connection structure to densify the connection layer, and connecting the SiC end plug and the SiC cladding tube densely to form the SiC cladding. According to the connection method for a SiC cladding for nuclear application in the present invention, rapid connection between the end plug and the cladding tube is achieved by using the resistance welding techology, thereby greatly saving the working time, and improving the connection efficiency; and a heat-affected zone of resistance welding connection is small, such that a nuclear fuel inside the cladding cannot be affected, and the reliability of the cladding is improved.
