INSTALLATION FOR PRODUCING DURABLE NUCLEAR FUEL PELLETS Russian patent published in 2023 - IPC B01J2/00 B01J2/22 

FIELD: fuel industry.

SUBSTANCE: formation of high-strength fuel granules of the required size from powder materials used in various fields of metallurgy, chemical industry, nuclear industry, in particular when operating with radioactive and toxic materials. The installation for producing durable nuclear fuel pellets contains a hopper-container with the initial product, a pressing unit, which is a flatbed press containing a shoe, a matrix, an upper punch, a lower punch, a transporting device; in addition, it contains a grinding unit, which is a mill with installed grinding nozzle in the form of a rotor with knives and a separating nozzle. The hopper-container is connected to the pressing unit via a sealed pipe with shut-off valves. A flatbed press can be used, for example, an electromechanical one.

EFFECT: production of high-strength fuel granules of the required size from radioactive and toxic materials.
