Abstract

L'invention concerne un système de contrôle de la position d'un assemblage combustible et le procédé afférent, ledit système comportant des organes de palpation pour mettre en oeuvre un palpage mécanique de la tête de l'assemblage combustible afin de déterminer une position absolue des assemblages combustible, au moyen de dispositifs mécanique de recopie de position de l'assemblage combustible. De préférence, le système comprend un bras articulé (30) de type SCARA et une perche instrumentée (40) montée en translation sur ledit bras articulé (30), une tête de mesure (50) étant disposée sur la perche instrumentée (40).The invention relates to a system for controlling the position of a fuel assembly and the related method, said system comprising palpation members for carrying out mechanical probing of the head of the fuel assembly in order to determine an absolute position of the fuel assembly. fuel assemblies, by means of mechanical devices for copying the position of the fuel assembly. Preferably, the system comprises an articulated arm (30) of the SCARA type and an instrumented pole (40) mounted in translation on said articulated arm (30), a measuring head (50) being placed on the instrumented pole (40).
