Machine-replaceable plasma-facing tile for fusion power reactor environments

摘要

An apparatus and method are disclosed for machine-replaceable plasma-facing tiles for fusion-power reactor environments. The apparatus and method involve a tile that is fish-scale shaped, and a tile support tube that is attached to the back portion of the tile. The tile support tube includes at least one coolant channel and at least one guard vacuum channel. In one or more embodiments, the method for removing the tile comprises providing a tile that is installed in a manifold channel of a first wall of a fusion power reactor, rotating the tile such that it is in an install/removal orientation, inserting two tines of a removal tool between the outer edges of the tile and the first wall of the fusion power reactor, rotating the removal tool such that the two tines grasp the tile support tube, and lifting the tile away from the wall with the removal tool.

主权项

1. A method for installing a replaceable plasma-facing tile for fusion power reactor environments, the method comprising:
inserting a tile support tube of the replaceable plasma-facing tile into a manifold channel of a first wall of the fusion power reactor such that the tile is in an install/remove orientation, wherein the tile support tube is attached to a back portion of the tile and the tile support tube comprises at least one coolant channel and wherein the tile support tube is configured to provide direct contact between coolant from the at least one coolant channel and the back portion of the tile, and wherein the at least one coolant channel is perpendicular to the back portion of the tile; and rotating the tile until the tile is in a locked orientation in the manifold channel of the first wall of the fusion power reactor.
