Liquid metal cladding used for fusion reactor and based on bionic design

Abstract

The invention discloses a liquid metal cladding used for fusion reactor and based on a bionic design. The liquid metal cladding can solve the problem that an insulating coating is corroded by a lithium-based proliferation agent and a cooling agent. The liquid metal cladding comprises the liquid lithium-based proliferation agent, wherein a liquid middle layer is arranged outside the liquid lithium-based proliferation agent, and a liquid cladding pipe wall coats the liquid middle layer; a runner insert is arranged in the middle of the liquid middle layer; the runner insert adopts a 3D-printed layer; and the liquid middle layer selects liquid metal / alloy / molten salt as a middle layer material. The liquid metal cladding has the beneficial effects that the liquid lithium-based proliferation agent and the cooling agent can be prevented from corroding the insulating coating in virtue of a bionic fusion reactor liquid cladding design and addition of the liquid middle layer.

Description

technical field [0001] The invention belongs to the technical field of liquid cladding in fusion reactors, in particular to a fusion reactor liquid metal cladding based on bionic design. A fluid intermediate layer is added between the lithium-based tritium breeder and coolant and the cladding structure material, which can prevent lithium from corroding the insulating coating. Background technique [0002] Controlled nuclear fusion is the ultimate solution to energy problems. Magnetic confinement nuclear fusion is the fusion method that is most likely to be realized in engineering, and the reaction currently used is tritium-deuterium fusion. The deuterium is extracted from seawater, the initial tritium is provided by the fission reactor, and the fusion reactor must be self-sufficient in tritium during operation. In addition, the energy generated in the fusion reactor also needs to be transmitted to be converted into electrical energy. These functions need cladding to under...
