APPARATUS FOR COLLECTING SPILLS OF SPENT NUCLEAR FUEL PELLETS Russian patent published in 2014 - IPC G21C19/32 

FIELD: physics.

SUBSTANCE: invention relates to means of ensuring safety when reloading spent fuel assemblies of the VVER-100 reactor from transfer baskets into storage covers, and is intended for use in water-filled spent nuclear fuel storages as an emergency tool. The apparatus for collecting spills of spent nuclear fuel pellets comprises a bar mounted on a hoisting apparatus with a protective cup mounted in the lower part of said bar. A collector, having a receiving tray and a dispensing tray, is mounted between plates of the cup such that it can be rotated by torsional springs. A scraper is mounted in the receiving tray such that it can be rotated by torsional springs, and the force of the torsional springs of the collector is greater than that of the torsional springs of the scraper. A rope is tied to the scraper, said rope being connected to a drive which is mounted in the top part of the bar. A funnel is placed on the rotation path of the dispensing tray. The drive of the scraper used is a handle - lift latch, which is movable on a longitudinal groove in the bar and fixed in transverse grooves connected to the longitudinal groove.

EFFECT: facilitating the unloading of collected pellets into a container, minimal maintenance.
