Abstract:
New material compositions, designs and configurations for components for an apparatus that produces a neutron flux such as a nuclear fusion reactor, and methods of manufacturing said new components.
Abstract:
Methods, apparatuses, devices, and systems for producing and controlling and fusion activities of nuclei. Hydrogen atoms or other neutral species (neutrals) are induced to rotational motion in a confinement region as a result of ion-neutral coupling, in which ions are driven by electric fields. The controlled fusion activities cover a spectrum of reactions including aneutronic reactions such as proton-boron-11 fusion reactions.
Abstract:
Zusammengefasst betrifft die Anmeldung ein Metallrohr, das zumindest eine Folie (10; 10'; 10"; 10"'; 10""; 10S) aus einem Refraktärmetall aufweist. Dabei weist ein Rohrmantel (2) des Metallrohrs (1) eine Mehrzahl von Lagen Folie (10; 10'; 10"; 10"'; 10""; 10S) aus Refraktärmetall auf, und zumindest zwei Lagen Folie (10; 10'; 10"; 10"'; 10""; 10S) aus Refraktärmetall sind zumindest bereichsweise stoffschlüssig miteinander verbunden. Die Erfindung betrifft weiterhin eine Verwendung eines Metallrohrs als Strukturbauteil, ein Verfahren zum Herstellen eines Metallrohrs, ein metallisches Strukturbauteil und einen Divertor.
Abstract:
Un composant de première paroi pour réacteur de fusion nucléaire comprend un élément en alliage de cuivre (3), une couche intercalaire métallique (6) en niobium et un élément en béryllium (4), directement en contact avec la couche intercalaire métallique (6). La couche intercalaire en niobium (6) est, de plus, avantageusement associée à une couche réductrice des contraintes mécaniques (8), constituée par un métal choisi parmi le cuivre et le nickel. Cette couche réductrice des contraintes mécaniques (8) est, en particulier, disposée entre la couche intercalaire en niobium (6) et l'élément en alliage de cuivre (3). De plus, lorsque la couche réductrice des contraintes mécaniques (8) en cuivre pur, une couche en nickel pur peut être interposée entre le niobium et le cuivre pur avant le soudage par diffusion. Un tel composant présente l'avantage d'avoir un comportement en fatigue thermique amélioré tout en évitant la formation de composés intermétalliques à la jonction entre le béryllium et l'alliage de cuivre.
Abstract:
A method, system, and apparatus are disclosed for a complex shape structure for liquid lithium first walls of fusion power reactor environments. In particular, the method involves installing at least one tile on the surface area of the internal walls of the reactor chamber. The tile(s) is manufactured from a high-temperature resistant, porous open-cell material. The method further involves flowing liquid lithium into the tile(s). Further, the method involves circulating the liquid lithium throughout the interior network of the tile(s) to allow for the liquid lithium to reach the external surface of the tile(s) that faces the interior of the reactor chamber. In addition, the method involves outputting the circulated liquid lithium from the tile(s). In one or more embodiments, the reactor chamber is employed in a fusion reactor. In some embodiments, the tile is manufactured from a ceramic material or a metallic foam.
Abstract:
The invention refers to a method useful for obtaining junctions having high qualities of mechanical resistance and capabilities of heat conduction between materials with different physical properties, and in particular ceramic/metal junctions or ceramic/metal composites in which the different thermal expansion coefficient entails remarkable stresses in the interface both during the junction process and their industrial application. The issues solved with the proposed method are the metal's difficulty of wetting the surfaces to be coupled and the general low mechanical resistance to tensile stress of ceramics or ceramic compounds. The first issue is solved with the application of a Titanium-base alloy that, by combining with the ceramic at a surface level enables metal to wet the surface. The second issue is solved by increasing the specific surface of the ceramic or compound, machining it through long-pitch multi-start thread.
Abstract:
A plasma-facing component for a plasma chamber, comprising: a plasma-facing target surface; an inlet through which to receive a coolant fluid and an outlet through which to expel the coolant fluid; and a plurality of internal cooling channels. Each cooling channel is connected to the inlet by a plurality of feed channels and to the outlet by a plurality of return channels, the feed channels being configured to direct coolant fluid against a region of a wall of the cooling channel. Respective openings of the feed and return channels into the cooling channel are arranged in non-overlapping repeating units along a length of the cooling channel. Each unit comprises openings of at least one feed channel and at least one return channel.

Abstract:
The invention relates to a method for producing a tile-substrate assembly 1 which comprises an array of tiles 3 bonded to a substrate 2, said method comprising: arranging the tiles 3 in an array on the substrate 2; bonding the tiles 3 to the substrate 2 to form a tile-substrate assembly 1, wherein the step of bonding is performed while adjacent tiles 3 in the array are separated by spacers 4 comprising a spacer material which remains solid during bonding of the tiles 3 to the substrate 2, and removing the spacers 4 from the tile-substrate assembly 1 by a removal process which comprises physically or chemically altering the bulk structure of the spacer material.
