Abstract
The apparatus for positioning a fuel assembly () comprises, on a respective side of the core support plate () and the upper core plate () directed towards an endpiece () of the fuel assembly () at least two projecting positioning pins () adapted to engage in openings in the lower endpiece () or upper endpiece (). Each of the positioning pins () is fixed in a blind opening () comprising a threaded bore and a support surface perpendicular to the axis of the blind opening () and comprises a flange adapted to come into contact with the support surface when the positioning pin () is screwed into the threaded bore. A gudgeon enables the positioning pin to be locked to secure it against unscrewing. The invention also relates to a process and apparatus for replacing damaged positioning pins on the core support plate () or on the upper core plate ().
