Heat pipe-cooled mixed fuel reactor system

Abstract

The invention discloses a heat pipe-cooled mixed fuel reactor system. The heat pipe-cooled mixed fuel reactor system includes a reactor core active zone, a liquid storage tank, control drums, a reflecting layer and a reactor core cylinder body, wherein the reactor core active zone is composed of multiple hexagonal fuel components, multiple heat pipes are evenly distributed inside the fuel components, the reflecting layer is located on the periphery of the reactor core active zone, multiple symmetrically-arranged control drums are arranged inside the reflecting layer, and the liquid storage tank is arranged below the reactor core active zone. The reactor core active zone, the liquid storage tank, the control drums and the reflecting layer are all arranged inside the reactor core cylinder body. The reactor core of the invention has advantages of both a solid reactor core and a liquid reactor core, and the critical size of the reactor core can be changed by the discharge of a liquid fuelin an accident, so as to realize emergency shutdown of the reactor and improve the inherent safety of the reactor.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactor engineering, in particular to a heat pipe cooling solid-liquid mixed fuel reactor system capable of effectively avoiding reactor core meltdown accidents. Background technique [0002] Human beings have been looking for new energy sources that can replace fossil fuels, and among many new energy sources, nuclear energy is considered to be a new energy source with more development prospects than wind energy and solar energy. It has irreplaceable advantages such as high power, long life, cleanliness and stability. The result of a fission reaction in a reactor core is usually the production of two fission fragments or smaller nuclei, two or more fast-moving high-energy neutrons, and significant heat. The new neutrons produced by the fission reactions will initiate new fission reactions, forming a continuous chain fission reaction. According to the cooling method of the core, the reactor can b...

AI Technical Summary

Problems solved by technology

[0003] The current nuclear reactors are mainly divided into two categories: solid fuel and liquid fuel. Among them, the solid fuel reactor has a stable and compact structure, but has low heat transfer efficiency and poor safety.

Reactors that use molten mixed salt as liquid fuel have high heat transfer efficiency, strong safety, and good neutron economy. Special external influence conditions may cause volume fluctuations in the larger radius liquid core, and there is a risk of unexpected core shutdown
