摘要： An object of the invention is to provide a nuclear reactor fuel rod in which a SiC material is used as materials of a fuel cladding tube and an end plug, and air tightness, heat resistance, and corrosion resistance are provided at a bonding portion between the fuel cladding tube and the end plug, and to provide a fuel assembly in which nuclear reactor fuel rods are bundled. According to the invention, a nuclear reactor fuel rod is a fuel rod for a light-water reactor. The nuclear reactor fuel rod includes a fuel cladding tube and an end plug, both of which are formed of a silicon carbide material. A bonding portion between the fuel cladding tube and the end plug is formed by brazing with a predetermined metal bonding material interposed, and/or by diffusion bonding. The predetermined metal bonding material has a solidus temperature of 1200°C or higher. An outer surface of the bonding portion, and a portion of an outer surface of the fuel cladding tube and the end plug, which is adjacent to the outer surface of the bonding portion are covered by bonding-portion coating formed of a predetermined coating metal. The predetermined metal bonding material and the predetermined coating metal have an average linear expansion coefficient which is less than 10 ppm/K.
