Problems solved by technology

However, a disadvantage of the processes described in these patents is that they are complex and accordingly the parts produced in the described manner are very expensive
Also, due to engineering limitations of the process, the techniques described above can only be applied to tile-like structures

Embodiment 1

[0029] Fusion reactor splitter plates 1 are fabricated as tiled tiles (see figure 1 ). In a first step, a tungsten sheet 2 of 20 x 40 x 6.5 mm is cut from a tungsten rod with a diameter of 60 mm. Tungsten flakes are cut from tungsten rods in such a way that the height of the flakes (6.5 mm) is parallel to the axis of the rod). In this way, the particles are aligned in the direction of the main heat flow in the future. Then, the intermediate sheet 3 is cut out from a plate made of a tungsten-copper composite material (referred to as T750) with a copper content of 15% by weight, and has a thickness of 2 mm, a width of 20 mm, and a length of 40 mm.

[0030] In a suitable casting system, a tungsten sheet 2, a 0.1 mm thick OHFC copper foil, a T750 intermediate sheet 3 and a 20 x 40 x 10 mm OFHC copper block 4 are stacked. Next, the stack was post-cast with OHFC copper in an inert gas furnace under a hydrogen atmosphere at 1250°C. Hold at this temperature for 30 minutes to ensur...

Embodiment 2

[0035] Figure 4 The splitter plate 1 shown in is fabricated as a monolithic structure in a similar process. A channel with a length of 10 mm and a diameter of 15.2 mm is processed in the center of the tungsten block 2 of 30×20×10 mm.

[0036] The ring 3 with an outer diameter of 15mm, a wall thickness of 1mm and a length of 10mm is made of a plate of tungsten-copper composite material (marked as T800) with a copper content of 20% (weight percent).

[0037] Insert an OHFC copper foil with a thickness of 0.1 mm, a ring 3 made of T800, and an OFHC copper rod with a diameter of 13 mm and a length of 15 mm into a channel machined in a tungsten block, in which the sequence of materials is as follows figure 2 shown. Next, the punches were post-cast with OFHC copper in an inert gas furnace under a hydrogen atmosphere at 1250 °C and kept at this temperature for 30 min. After removing the post-cast monolith, a 12 mm diameter hole was punched in the post-cast copper concentric to th...

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. [0003] The...
