Abstract

The invention provides a radial modular nuclear reactor, belongs to the technical field of nuclear engineering and nuclear technology, in particular relates to the radial modular nuclear reactor, andsolves the problems of large volume, inconvenient replacement of fuel components, easy occurrence of accidents and poor heat exchange effect of the existing nuclear reactor. The radial modular nuclearreactor comprises a reactor core and control rods, wherein the reactor core comprises a plurality of fuel assembly modules, the plurality of fuel assembly modules are arranged along the circumferential direction to form an annular structure, the center of the annular structure is a central channel, the control rods pass through the fuel assembly modules along the axial direction, the fuel assembly modules comprise a plurality of fuel rods and heat transfer substances, the plurality of fuel rods are distributed along the radial direction of the reactor core, the plurality of fuel rods are distributed in an array and are provided with gaps, and the outer wall of the fuel rods is in contact with the heat transfer substances. The radial modular nuclear reactor is mainly used for radially arranged modular nuclear reactors.

Description

technical field [0001] The invention belongs to the field of nuclear engineering and nuclear technology, in particular to a radial modular nuclear reactor. Background technique [0002] Fuel assemblies in existing nuclear reactor designs are arranged axially. The fuel assembly and the fuel rods therein transfer heat to the coolant entering the core from one end in the axial direction, and realize heat exchange parallel to the pipe direction. This type of nuclear reactor has a large volume and takes up more space, and it is inconvenient to replace fuel assemblies. The fuel rods used are longer and easily deformed, which increases the probability of accidents. The contact area between the fuel rods and the heat transfer material is small, and the heat transfer effect is poor. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention proposes a radial modular nuclear reactor. [0004] To achieve the above object, the present i...
