The invention provides a component or composite part, such as a divertor plate for the &ldquo;first wall&rdquo; of a fusion reactor, adapted to endure a high thermal load, which is made, at least in some sections, of tungsten or a tungsten alloy. In accordance with the invention, the sections are not constructed massively from tungsten or a tungsten alloy, but rather are made as a laminated packet, in order to improve the susceptibility to fissures.

Composite for high thermal stress

A process for manufacturing a structural element capable of carrying high thermal loads, such as a heat shield for fusion reactors. The structural element comprises components of high heat-resistant material (such as graphite) joined to metallic components. A metallic, ductile intermediate layer is applied to the components of high heat-resistant material and then, the components of high heat-resistant material and metallic components are joined by high-energy beam welding.

Process for the manufacture of a structural element capable of carrying

A process for the manufacture of a cooling unit particularly for fusion reactors. The cooling unit consists of one or more parts made of heat-resistant material, preferably graphite, which are joined to at least one metallic coolant conduit, preferably made of copper or a copper alloy. The joint is produced by bringing molten metal of the coolant conduit into contact with the parts made of heat-resistant material. One or more metals of the secondary groups IV and/or V of the periodic table are introduced at the contact surface between the coolant conduit and the heat-resistant parts. The metal of the coolant conduit is thereafter cooled to solidify the coolant conduit in the desired shape.
