Compact reactor core applied to land mobile power supply and land mobile power supply

Abstract

The invention provides a compact reactor core applied to a land mobile power supply and the land mobile power supply, relates to the technical field of nuclear reactors, and is designed for solving the problem that the structure of the existing land small-sized gas-cooled nuclear reactor is not compact enough. The compact reactor core applied to the land mobile power supply comprises a reactor core active area, a reflecting layer wrapping the periphery of the reactor core active area and a pressure bearing layer wrapping the periphery of the reflecting layer, the reactor core active area comprises a plurality of hexagonal fuel elements, and the plurality of fuel elements are closely arranged in a honeycomb shape; the center of the fuel element is a fuel rod with a circular cross section, and the hexagon is a coolant inlet channel; the fuel rod comprises uranium carbide fuel; the cooling agent is helium and xenon mixed gas. The land mobile power supply comprises the compact reactor core applied to the land mobile power supply. The compact reactor core applied to the land mobile power supply and the land mobile power supply provided by the invention are more compact in structure on the premise of the same power.

Description

technical field [0001] The invention relates to the technical field of nuclear reactors, in particular to a compact core applied to a land mobile power supply and the land mobile power supply. Background technique [0002] At present, the technical route of land-use small nuclear reactors is mainly based on heat pipe reactors and gas-cooled reactors. For the heat pipe stack, although it can theoretically achieve a higher output power, its power output is more sensitive to the size and number of heat pipes, and it is extremely important for industrial manufacturing to drill hundreds of thousands of millimeter-scale channels on the substrate. big challenge. Therefore, from the perspective of feasibility, air-cooled nuclear reactors will be a better solution. [0003] Generally, a gas-cooled nuclear reactor includes a core, wherein fuel elements are inside the core, and gas flows directly through the fuel elements as a coolant. The middle of the fuel element is fuel, and the...
