Description

technical field [0001] The invention relates to the technical field of cladding manufacturing technology in nuclear fusion devices, in particular to a connection process suitable for fusion reactor cladding containing complex water-cooling flow channel components. Background technique [0002] As a plasma-facing component, the cladding not only shoulders the tritium task, but because its first wall directly faces the plasma, it also protects the vacuum chamber and the superconducting magnet, and shields the fusion reaction radiation. At the same time, the neutron flow and heat flow generated by the fusion reaction will enter into the cladding, and the thermal energy generated by neutrons in the cladding due to the speed reduction and part of the energy in the heat flow are absorbed by the cooling system of the cladding, which can be used to generate electricity and cool As an important part of the cladding, the system directly affects the cooling effect and safe service of t...
