PORT-LIMITER OF A THERMONUCLEAR REACTOR Russian patent published in 2005 - IPC

FIELD: thermonuclear engineering; production of the power thermonuclear equipments of the tokamak type.

SUBSTANCE: the invention is pertaining to the field of thermonuclear engineering, in particular, to production of the power thermonuclear equipments of the tokamak type. The port-limiter of a thermonuclear reactor contains the vertical panel combined in a pack and supplied with the cooling ducts and forming by their lateral butts the front and the rear walls of the port-limiter. The vertical panel are combined by means of a cartridge and fastening elements in the form of threaded pins and nut. At that the internal surface of the cartridge has vertical grooves, in which the panels are installed. At that the cartridge and the panels have horizontal pinholes for the threaded pins and made along the height of the panels equidistant to rear wall. The technical result consists in a decrease of the thermomechanical tensions in the vertical panels at break-ups of the plasma. Besides the offered invention design allows to ensure high accuracy of interposition of the vertical panels due to improved conditions of the heat output from each panel.

EFFECT: the invention ensures the decreased thermomechanical tensions in the vertical panels at breakaways of the plasma, high accuracy of interposition of the vertical panels, an increase of the heat output from each panel.
