Modularized transverse prism type air-cooled micro-reactor core system

Abstract

The invention discloses a modularized transverse prism type air-cooled micro-reactor core system which comprises a fuel assembly, a drum control rod, an absorber ball and a reflecting layer; the reflecting layer covers a reactor core formed by the fuel assembly; the drum control rod is arranged on the side reflecting layer; the reactor core is provided with a central graphite ribbon; an absorber ball channel is arranged in the central graphite ribbon; the fuel assembly is provided with fuel rod channels, coolant channels and beryllium oxide rods which are regularly arranged at intervals so as to enhance moderation. The system has the beneficial effects that the fuel is microencapsulated by the ceramic so that the fuel is prevented from being eroded; the system has the advantages of high heat capacity, high temperature resistance, high heat conductivity, high slowing-down ratio, small thermal neutron absorption cross section and the like; the inherent safety of automatic thermal shutdown only depending on temperature negative feedback is achieved; the drum control rod and the absorber ball not only can effectively control reactivity and ensure the safety of the reactor core, but also can save space, so that the reactor core system and the reactor can be arranged in a common container and are convenient to transport.

Description

Technical field [0001] The present invention belongs to the field of nuclear reactor engineering, and in particular, the present invention relates to a modular transverse prismatic air-cooled microcomputer core system. Background technique [0002] The rapid development of the economy improves energy demand, but traditional coal and other fossil fuels will bring serious environmental issues, which prompted my country's continuous improvement and development of clean energy, and continuously optimizes existing energy structures and reduces fossil fuel. The ratio in energy. In various types of new energy, the nuclear energy has a clean, high energy density, and almost unsained with a low greenhouse gas, the fuel transport pressure is low. In recent years in the 21st year, nuclear energy has been continuously developed, and has become an important option for my country's improvement of energy structure and has continued to strengthen in the energy development strategy. As of the end...

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.
