Abstract

A laminar component (1) for a fusion reactor, which can accommodate high thermal stresses, comprises tungsten or a tungsten alloy with a tungsten content greater than 90 wt% in the plasma region (2), and copper or a copper alloy in a heat removal region (4). A metallic component (5) is against the copper region. Preferred Features: The latter has a conductivity greater than 250W / mK and a mean granular size in excess of 100 micron. A refractory metal-copper laminate is between them in an intermediate region (3). The laminate is 0.1-4 mm thick, and the refractory metal content is 10-40 Vol%. The refractory metal phase forms a skeleton.

Description

technical field

[0001] The invention relates to a highly heat-resistant layered component of a fusion reactor, which at least comprises copper made of tungsten or a tungsten alloy with a tungsten content > 90% by weight, facing the plasma zone, made of copper with a thermal conductivity > 250 W / mK and an average particle size > 100 μm or copper alloy with a region in between consisting of a refractory metal-copper composite. Background technique

[0002] For stationary fusion reactor operation, powers of up to 10 MW / m in the surface area of ​​the first wall component (also known as PFC, plasma facing component) are expected 2 . When plasma disruption occurs, around 20GJ can be released at some point within a few milliseconds. The development of PFCs specially designed for use in regions of maximum energy concentration, such as diverters, baffles, and confinement regions, reflects key factors in the technical implementation of fusion research results.
