Abstract
A nuclear fuel assembly bottom nozzle, of the type including a perforated plate to allow water to pass through it, the nozzle having lateral faces, and at least one anti-debris element positioned on a lateral face to block out debris likely to infiltrate between the bottom nozzle and another adjacent bottom nozzle, characterized in that, in the free state, the or each anti-debris element permanently projects from the lateral face on which it is positioned, the or each anti-debris element being elastically deformable so as to retract towards the lateral face in the event of a force being exerted on the anti-debris element towards the lateral face.

A nuclear fuel assembly bottom nozzle comprising:
- a perforated plate to allow water to pass through the perforated plate;
- lateral faces;
- and
- at least one anti-debris element positioned on one of the lateral faces to block out debris likely to infiltrate between the bottom nozzle and another adjacent bottom nozzle,
- wherein in a free state, the at least one anti-debris element permanently projects from the lateral face on which the anti-debris element is positioned, the at least one anti-debris element being elastically deformable so as to retract towards the lateral face when a force is exerted on the at least one anti-debris element towards the lateral face.
