A device for loading fuel rods into the capsule (8) is fixed to an upper open end of the structure (20). Defective rods are removed one by one and the empty capsules containing no rods are introduced one by one into the loading structure (20). For each of the capsules (8) that are intended to receive a defective rod, an upper end cap (14) is unscrewed from the capsule, a defective rod is introduced into the capsule (8) through a guide device belonging to the loading device, the upper end cap (14) is screwed back onto the capsule (8) and the capsule (8) containing the rod is placed in a slot in the support structure (20).</p> |
