Description

technical field

[0001] The invention relates to a cladding installation and cooling structure, in particular to a multifunctional backboard for future fusion reactor multiplication cladding. Background technique

[0002] With the development of industry and the gradual depletion of fossil energy, magnetic confinement fusion is one of the important research directions of energy development. The cladding system is an important part of a fusion reactor and one of the key technologies for realizing nuclear fusion power generation. Its main function is to generate enough tritium to sustain the fusion reaction and convert heat energy into electricity. In the future, the cladding of fusion reactors generally adopts a modular design to facilitate remote maintenance of cladding modules. However, with the enlargement of fusion reactor devices, more and more cladding is divided into blocks, and the maintenance methods of individual modules are greatly increased. Maintenance ti...
