The reactor core structure comprises fuel elements 1, heat pipes 2, a limiting base body 3, a cylinder container 4 and a reactor core upper grid plate 5, wherein the fuel elements 1 and the heat pipes 2 are arranged in the cylinder container 4 in a honeycomb shape, the limiting base body 3 is arranged between the arrangement of the fuel elements 1 and the heat pipes 2 and the inner wall of the cylindercontainer 4, and the reactor core upper grid plate 5 is arranged on the cylinder container 4.

Description

technical field [0001] The invention belongs to the technical field of nuclear fuel elements, and in particular relates to a core structure of a heat pipe reactor fuel element using a hexagonal prism cladding. Background technique [0002] The heat pipe is a high-efficiency heat-conducting element with small size and high reliability. The use of heat pipes in the reactor to conduct heat can avoid the large-scale loop structure in the original reactor, avoid the use of high-power mechanical pumps and other equipment, and greatly simplify the original reactor system. Except that the working medium inside the heat pipe is a gas-liquid two-phase medium, the whole core material is a solid structure, which reduces the problems of chemical corrosion and flow-induced vibration. The heat pipe reactor has small core size, high inherent safety, low noise, and simple and reliable system equipment. Combined with thermocouple, thermoacoustic, thermophotovoltaic and other power generation...
