Abstract

The invention discloses a multifunctional back plate used for installing and cooling future fusion reactor breeding cladding. The back plate comprises a supporting back plate body. The supporting back plate body is provided with a back plate self-cooling circulation pipeline, a breeding cladding cooling pipeline and a tritium extraction pipeline, the breeding cladding cooling pipeline is connected with the back plate self-cooling circulation pipeline through a series of partition boards, the contact surfaces of the back plate self-cooling circulation pipeline and the breeding cladding cooling pipeline are coated with heat-insulating material coatings, the surface of the tritium extraction pipeline is coated with a tritium leakage prevention coating, and the supporting face of the supporting back plate body is provided with a flexible support. The back plate meets the requirements of cladding installation and cooling, meanwhile achieves the aims of self-cooling of the back plate and tritium leakage prevention, facilitates centralized design of the cladding, improves maintenance efficiency of the cladding, and meanwhile solves the back pipeline integration problem of the cladding.

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...

Problems solved by technology

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 time and complexity

At the same time, the increase in the number of cladding blocks will inevitably require more helium cooling pipelines to meet the cooling needs of each piece of cladding, and the integration and fixing of a large number of pipelines in a limited space has also become one of the difficulties in design
