DEVICE FOR CONTINUOUS MONITORING OF DENSITY OF PRESSED POWDER OF NUCLEAR FUEL DURING ITS LOADING IN DEVICE FOR FUEL TABLETS PRESSING Russian patent published in 2016 - IPC G21C17/06 

FIELD: power industry.

SUBSTANCE: device contains a silo 1 with pressed powder, connected by vertical loading pipe 2 with tablets pressing device 3. Near the pressing device 3 at opposite sides of the pipe 2 the gamma source 4 is installed (at sufficient quantity of pressed powder for registration its own gamma radiation can be used), and detection unit 5, connected with registration unit comprising signal transducer 6, and electronic graphic register 7, connected in series with communication lines 8. The registration unit is made with possibility to communicate signals to control system of the pressing device to regulate pressed powder delivery or for its shutdown.

EFFECT: timely monitoring of density decreasing of pressed powder and pressing termination to exclude production of the fuel tablets with wrong geometry and reduced density.
