Abstract

Procédé et dispositif électronique d'aide à la surveillance d’un élément de réacteur nucléaire, programme d’ordinateur et système associés Ce procédé d'aide à la surveillance d’un élément de réacteur nucléaire, mis en œuvre par un dispositif électronique, comprend les étapes : - (120) entrainer un algorithme d'intelligence artificielle ; - (140) acquérir une image de l’élément ; - (150) estimer, à partir de l’image et via l’algorithme d'intelligence artificielle, une présence d’un défaut de l’élément ; - (160) afficher l’image de l’élément ; et - si au moins un défaut est estimé présent, (170) générer une alerte. Lors de l’étape d’estimation, une entrée de l'algorithme d'intelligence artificielle est une image d’une zone comportant l’élément, et une sortie est un niveau de confiance quant à une absence de défaut de l’élément pour ladite zone. Si le niveau de confiance est inférieur à un seuil, alors un défaut est estimé présent. Lors de l’étape d’entraînement, seules des images de l’élément sans défaut sont fournies à l’entrée de l'algorithme d'intelligence artificielle. Figure pour l'abrégé : Figure 4
