Modular pressure pipe type air-cooled micro-reactor core

Abstract

The invention discloses a modular pressure pipe type air-cooled micro-reactor core which comprises a fuel assembly, a reflecting layer and a control rod assembly, the fuel assembly is placed in the pressure pipe so that the pressure pipe is used as a pressure-bearing boundary of a reactor core, and the reflecting layer and the control rod assembly are mounted outside the pressure pipe. The modular pressure pipe type air-cooled micro-reactor core has the beneficial effects that the fuel assembly is put into the pressure pipe, modularization is formed through pressure bearing of the pressure pipe, installation is convenient, and the problems that the high-temperature gas cooled reactor is large in number of transportation elements, complex in assembly and slow in response deployment are solved. The temperature of the reactor core outside the pressure pipe is low, so that the high-temperature tolerance requirements of the control rod part, the pipe outside moderation material and the reflecting layer material are reduced. The reactor core has excellent inherent safety, design flexibility, environmental adaptability and transportation and assembly convenience, and has great market potential in the fields of remote mountainous area power supply, aerospace, island power supply, deep sea power supply and the like.

Description

technical field [0001] The invention belongs to the field of nuclear industry, and in particular relates to a modular pressure tube type air-cooled micro-reactor core. Background technique [0002] Energy is an important basis for social and economic development, and the increasingly prominent problem of environmental pollution poses a higher challenge to the optimization of energy structure. As a clean, stable, and high-power-density new energy source, nuclear energy is the best candidate for base-load electricity. The safety of nuclear power has always been the focus of general public concern, and it is also the direction of efforts of nuclear power researchers. Especially after the Fukushima accident in Japan, people paid more and more attention to the safe use of nuclear energy, and the design and development of various advanced nuclear energy systems accelerated. [0003] High-temperature gas-cooled reactor, as one of the advanced reactor types of the fourth-generatio...

AI Technical Summary

Problems solved by technology

However, a large number of components such as fuel assemblies, reflective layers, and control rods require a long period of installation and commissioning on site before they can reach normal operating conditions. It is difficult to meet the requirements of container transportation, simple assembly, and rapid deployment in special application scenarios.
