摘要： 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.

摘要： The present invention relates to the field of energy generation. More particularly, the present invention relates to devices, systems, and methods for use in generating energy with graphite-moderated nuclear reactors. Embodiments of the invention include devices, systems, and methods for use in generating power that use graphite having a neutron diffusion coefficient higher than that of Acheson graphite. Specifically included embodiments comprise providing artificial graphite manufactured under high pressure during the graphitization process to cause a larger neutron diffusion coefficient than graphite not produced under pressure (Acheson graphite). Suitable graphite according to the invention includes graphite prepared under high pressure during the graphitization phase of the manufacturing process, which produces graphite with an increased diffusion coefficient by reducing the microcrystal diffraction scattering and increasing the non-diffractive (inelastic) scattering of the graphite.

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.

摘要： Systems and methods for providing a molten salt reactor are described. While the systems can include any suitable component, in some cases, they include a graphite reactor core (70) that defines an internal space (135), with multiple fuel wedges (180) being received in the internal space, and with the wedges each defining a fuel channel (155) extending from a first end to a second end of each of the wedges. In some cases, the reactor further includes a fuel pin rod (160) that defines an internal fuel conduit and that is disposed between at least two of the wedges. In some cases, the reactor core defines a fuel ingress port (151) and a fuel egress port (152). In some such cases, the reactor core is rotatably received within a reactor housing such that the ports are configured to become at least one of more occluded and less occluded as the reactor core rotates. Other implementations are described.
