Abstract

The invention relates to a portable passive nuclear power reactor, and belongs to the technical field of reactors. The portable passive nuclear power reactor comprises a shell, a neutron reflecting layer, a thermoelectric converter, a hydrogen inlet valve, a hydrogen regulator, fuel, a hydrogen conduction pipe, a heat pipe group and a current output terminal, wherein the shell defines a cylinder structure with an accommodating chamber; the accommodating chamber is divided into a hydrogen regulation chamber and a fuel chamber by the neutron reflecting layer; the thermoelectric converter is positioned on the upper part of the fuel chamber; the hydrogen inlet valve is positioned on the top of the shell; the hydrogen regulator is positioned in the hydrogen regulation chamber; the fuel is positioned in the fuel chamber; the hydrogen regulation chamber is communicated with the fuel chamber by the hydrogen conduction pipe; the heat pipe group is communicated with the thermoelectric converter and the fuel; the current output terminal is positioned outside the accommodating chamber, and penetrates through the shell to be communicated with the thermoelectric converter. According to the reactor disclosed by the invention, by utilizing the characteristic that hydrogenation and dehydrogenation performance of metal uranium can be changed along with the temperature, the design of the passive reactor utilizing the hydrogen as a neutron moderator and an operation control agent is realized.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a portable passive nuclear power reactor. Background technique [0002] In the context of human energy crisis, the effective use of nuclear energy is one of the ways to effectively solve the energy crisis in the near future and even in the future. Since the current mature controllable nuclear energy technology is mainly the fission reactor technology that utilizes the fission energy of heavy materials, all countries in the world are scrambling to develop advanced fission reactor technology in this field. Although the current mature and commercialized fission reactor nuclear power plants have been widely used, there are still considerable technologies worthy of further research to improve the safety and economy of its operation. In particular, the breakthrough of small reactor technology has made it initially have commercial development value, especially as people's understandin...
