A first-wall component of a fusion reactor has a heat shield and a heat sink. The heat shield is formed of a material from the group of graphite material, carbidic material, tungsten and tungsten alloy. The heat sink is formed of a spray-compacted copper alloy.

First-wall component for a fusion reactor with a heat sink of a copper alloy

The invention relates to a first-wall component of a fusion reactor, which comprises at least one heat shield of a graphitic material and a cooling tube of copper or a copper alloy. Arranged between the heat shield and the cooling tube is a tube segment, which is connected at least in certain regions to the heat shield and to the cooling tube via copper-containing layers.

A material composite has a part made from steel or a titanium-based material and a part made from a copper-based or aluminum-based material. The parts of the material composite are joined by way of an intermediate piece. The intermediate piece likewise comprises a region made from steel or a titanium-based material and a region made from a copper-based or aluminum-based material, which are connected by explosion welding. The parts of the material composite are connected to the regions of the intermediate piece which are in each case of the same type by means of a fusion or diffusion welding process.
