Abstract

La présente invention concerne un procédé pour entretenir l'intérieur du coeur d'un réacteur. Selon cette invention, un corps de protection contre les rayonnements est pourvu sur le rebord d'un caisson sous pression de réacteur, une conduite de guidage est fixée audit corps de protection contre les rayonnements et un rail de guidage est monté à l'intérieur de ladite conduite de guidage et permet de supporter un dispositif d'entretien qui est destiné à l'entretien de l'intérieur du coeur dans le caisson sous pression du réacteur. L'intérieur du coeur est entretenu par utilisation du dispositif d'entretien dans un environnement atmosphérique. Ce dispositif d'entretien, de structure relativement simple, permet d'entretenir rapidement et efficacement l'intérieur d'un coeur en service, même lorsqu'une gaine est montée dans le caisson sous pression du réacteur.
