摘要： A nuclear reactor includes a vessel having an outer wall and vessel bottom, and an enclosure delimited by a cylindrical inner wall disposed inside the vessel such that the inner wall and outer wall define a circuit with an annular cross-section. A support element is located adjacent the bottom of the enclosure to hold control elements of the core. A flow diffusion element is positioned between the support element and the vessel bottom and has a circular flat surface portion including disc shaped orifices of the same diameter. The space between the flat portion and the vessel bottom forms an unobstructed mixing zone to allow uniform distribution of flow rates of fluid circulated through the enclosure.

摘要： A riser cone has a lower end sized to engage a cylindrical lower riser section of a nuclear reactor and an upper end sized to engage a cylindrical upper riser section of the nuclear reactor. The riser cone defines a compression sealing ring that is compressed between the lower riser section and the upper riser section in the assembled nuclear reactor. In some embodiments the riser cone comprises: a lower element defining the lower end of the riser cone; an upper element defining the upper end of the riser cone; and a compliance spring compressed between the lower element and the upper element. In some embodiments the riser cone comprises a frustoconical compression sealing ring accommodating a reduced diameter of the upper riser section as compared with the diameter of the lower riser section.

摘要： A SiC ceramic material includes a bundle of SiC continuous fibers in a porous SiC ceramic matrix, has thermal insulation properties, a high level of strength and a high degree of toughness. A SiC ceramic structure is made of the SiC ceramic material. It is produced by preparing a pressure-sintered compact using a slurry prepared by mixing SiC powder and carbon powder in a liquid and by gasifying and releasing the carbon powder. The SiC ceramic structure can be produced by heating a reaction preparation containing a bundle of SiC continuous fibers and Si powder to a temperature equal to or higher than the melting point of silicon causing a reaction of the carbon component and Si powder and thereby obtaining a reaction-sintered compact, and by gasifying and releasing the carbon component from the reaction-sintered compact. The SiC ceramic can be produced by a chemical vapor deposition method.

摘要： A nuclear reactor and method for generating energy from fertile and fissile nuclear fuel material. The reactor may comprise a pressure vessel for housing a nuclear reactor core, the vessel having a lower vessel with an upwardly facing opening and a vessel closure head having a sealable access port. The vessel closure head may be positionable in differing positions relative to the lower vessel so that differing portions of the interior of the pressure vessel may be accessed through the access port. The lower vessel may include penetrations for lateral insertion of one or more reactor control blades into the interior of the lower vessel. The reactor core may comprise an inner driver region having substantially fissile nuclear fuel material, a breeder region substantially surrounding the driver region and having substantially fertile nuclear fuel material, a moderator substantially surrounding the breeder region, and a distal burner region having substantially fissile nuclear fuel material with higher fission product concentration than the driver region and being adaptable to receive neutrons from the driver and breeder regions. Generated heat from nuclear fuel in the reactor core may be removed by a gaseous coolant whereby the heated coolant is utilized to maintain the temperature of the moderator.

摘要： Core spray line riser repair apparatus and methods for axially restraining a reactor core spray line riser to a T-box are described. In one embodiment, the repair apparatus includes a sleeve, a threaded draw bolt extending through the axial bore, and a threaded block. The sleeve includes a substantially cylindrical main body having an axial bore extending therethrough and a flange at one end of the main body. The sleeve is configured to be inserted into the T-box until the flange abuts against the T-box. The draw bolt is configured to extend through the sleeve flange, the sleeve bore, and an opening in the core spray line riser. The draw bolt engages the block to draw the block in tight engagement with the core spray line riser.

摘要： A method and apparatus for improving the operating efficiency of a boiling water reactor is disclosed. Instead of coolant water being injected simultaneously at the bottom of the fuel rod assemblies and core bypass regions, the two flows then proceeding in parallel to the top of the reactor, the top of the bypass regions is sealed off and bypass coolant water is directed at the bottom of the sealing cover. This forces the bypass coolant water to flow down through the bypass regions. At the bottom of the bypass regions, provision is made to allow the bypass water to flow into the bottom of the fuel rod assemblies where it is entrained by the fuel rod coolant water flow. By converting flow through the core bypass region into a single series flow, increased operating efficiency is achieved.
