According to the double-layer electrically-charged waterway penetration piece, a first layer electrical isolation constraint structure is arranged in a second layer electrical isolation constraint structure concentrically to form an electrical isolation constraint structure; an insulation cavity is composed of the first layer electrical isolation constraint structure and the second layer electrical isolation constraint structure; the right end of the first layer electrical isolation constraint structure and the right end of the second layer electrical isolation constraint structure are arranged on a separating plate; the center of the separating plate is provided with a through hole; the left end of an external sleeve pipe is welded on the left side surface of the separating plate; the external sleeve pipe and the through hole on the separating plate are designed to be concentric; an ITER flange is provided with a plurality of bolt holes; the ITER flange is arrangedon a constraint barrier CP flange atmosphere side using ITER flange fastening bolts; a fourth ceramic tube is arranged in the external sleeve pipe; the left end of the fourth ceramic tube is designedto pass through the separating plate center through hole, the first layer electrical isolation constraint structure, an ITER flange center through hole, and a CP flange center through hole, and stretch into a vacuum side; an electrically-charged water pipe is arranged in the fourth ceramic tube, and is used for communicating the vacuum side and the atmosphere side.

Description

technical field [0001] The invention belongs to the technical field of fusion reactor penetrating parts, and in particular relates to a double-layer electrified waterway penetrating part used for the atmosphere side of a fusion reactor. Background technique [0002] In the deuterium-tritium fusion reactor, the penetrating parts of water and electricity penetrating the confinement barrier, and the penetrating parts of the electrified cooling water circuit are one of the commonly used important parts of fusion reactor engineering. Since the fusion reactor works in the working environment of deuterium-tritium fusion plasma, the working environment is harsh, such as: high temperature, radioactive radiation, thermal shock and mechanical shock, and various nuclear safety requirements: safety level of tritium and radioactive constraints, earthquake The safety level, vacuum level, tritium classification and remote manipulator operation classification level requirements make the wate...
