The aim of the invention is to provide an aligning device (6) for fuel elements (1) with which fuel elements (1) of a pressurized water reactor can be aligned in a comparatively easy and quick manner. To this end, the invention provides that an aligning device (6) for fuel elements comprises an aligning body (8), which extends in a longitudinal direction and whose lateral faces that are formed from side metal sheets (14) can be displaced out of a position of rest in a direction that is perpendicular to the longitudinal direction. The cross-sectional dimensions of the lateral faces of the aligning body in the position of rest are selected so that they are less than the corresponding cross-sectional dimension of a reference fuel element by a predetermined nominal value.

L'invention concerne un dispositif de disposition (6) destiné aux crayons de combustible (1) et conçu de manière permettre la disposition des crayons de combustible (1) d'un réacteur à eau sous pression de manière comparativement simple et rapide. A cet effet, un dispositif de disposition (6) destiné aux crayons de combustible (1) selon l'invention présente un corps de disposition (8) élargi dans le sens longitudinal et dont les faces latérales constituées de tôles latérales (14) se déplacent passant d'une position de repos à une position perpendiculaire au sens longitudinal. Les dimensions transversales des faces latérales du corps de disposition en position de repos sont sélectionnées avec une valeur nominale donnée inférieure à la dimension transversale correspondante d'un crayon de combustible de référence.
