Problems solved by technology

Nuclear fission power plants mainly use radioactive elements such as uranium and cesium as fuel. The reaction products are generally buried deep but will cause certain pollution to the environment. At the same time, the resources of radioactive elements on the earth are limited, and the radiation produced by them will also cause harm to human health.

Abstract

The invention provides an internal part cooling power generation system for a future tokamak fusion reactor. The system comprises a divertor cooling circuit, a cladding cooling circuit and a main cooling circuit. The system is characterized in that the divertor cooling circuit comprises a first heat exchanger, a pump and a divertor; a coolant is inflated by the pump from one side of the first heat exchanger, flows into the divertor, and flows back to the first heat exchanger from the other side of the divertor; the cladding cooling circuit comprises a first main circuit, a first auxiliary circuit and a supplemental coolant circuit; and the main cooling circuit comprises a second main circuit and a second auxiliary circuit. According to the invention, on the premise that a tokamak device can continuously stably operate, cooling and power generation are integrated, and the system has the advantages of stability, safety, reliability and high efficiency.

Description

technical field [0001] The present invention relates to the application field of nuclear energy technology, in particular to a cooling power generation system for internal components of a future Tokamak fusion reactor, that is, in the case of continuous operation of a magnetic confinement nuclear fusion device, the energy released by deuterium-tritium fusion is used to generate electricity while cooling its components. Internal components - divertor and cladding. Background technique [0002] At present, the earth's fossil energy reserves are limited and pollute the atmosphere, while renewable energy (wind energy, solar energy, tidal energy) is underutilized due to various restrictions, and countries around the world are facing problems such as energy shortage and environmental pollution. Therefore, people pay more and more attention to the development of nuclear power technology. A nuclear power plant is a power plant that uses the energy released by nuclear fission or fus...
