Device to load a sintering boat with nuclear fuel pellets, comprising a loading chute () delimiting a travel pathway () for the pellets, the loading chute comprising an upper end () intended to receive pellets and a lower end () intended to lie close to a sintering boat, said loading chute () comprising gates () forming an obstacle in the pathway of the pellets so as to fractionate said pathway, said gates () able to be actuated alternately, and the lower end () of the loading chute being movable so that it can be drawn close to and away from a bottom part of the sintering boat. A further subject-matter of the present invention is a method to load a sintering boat with nuclear fuel pellets, using a device according to the present invention.

Device to load a sintering boat with nuclear fuel pellets and loading method using said device

The objects (6) fall into a well (10) where their fall is slowed down by slanted blades (13) covered by a damping layer and situated in front of a counter-wall (14) from which they are separated by a gap (16). The counter-wall (14) is elastic so as to make the objects falling onto it rebound towards the lower blade. An outgoing track of the well (26) having a round shape is covered with a damping layer which absorbs the free fall energy at the outlet of the device. The invention can be applied to the continuous bulk carrying of fragile objects, such as pellets.
