RECEIVING PLATE OF DIVERTOR OF STATIONARY FISSION REACTOR Russian patent published in 2020 - IPC G21B1/13 

FIELD: physics.

SUBSTANCE: invention relates to a receiving plate of a divertor of a stationary thermonuclear reactor. Device contains a receiving surface facing the plasma and a heat removal zone connected to it, which includes a group of heat carrier supply nozzles and heat carrier supply channels connected to them. Receiving wall made of thin sheet of metal forms, with parallel to it support plate for installation of nozzles and side walls of closed cavity of heat removal zone, nozzles of pneumatic-hydraulic type are supplied to inner side of receiving wall fine-dispersed gas-drop heat carrier. At that, the sprayed heat carrier flow is directed to the wall by means of plate-shaped deflectors installed at an angle to the nozzles axis and connecting the mechanically receiving wall and the bearing plate, deflectors have steam outlet openings at the point of contact with the receiving wall, thereby separating the closed heat removal cavity into the heat carrier supply and discharge zone, and the heat carrier discharge channel is connected to the discharge zone.

EFFECT: technical result is higher efficiency of cooling of receiving plate of divertor of stationary thermonuclear reactor at high densities of incoming heat flow, low temperature of the receiving surface, limited flow of the evaporated substance from the surface of the plate to tokamak plasma, high reliability owing to low level of electromagnetic loads in the structure.
