Zusammenfassung:The process for limiting the supporting effort applied to a nuclear reactor fuel assembly comprises making and inserting an elastic bush (15) that engages with a friction fit on the end of centering pin between the fuel assembly and a cage end unit (7). The bush has at least two lengthwise slits (17) between its fixing section (15a) and its free end, forming two or more flexible branches (16) in a section with an outer diameter smaller than that of the centering aperture (18).
