Abstract

L'invention concerne un procédé pour enlever les structures intérieures du corps cylindrique dun générateur de vapeur d'une installation nucléaire selon lequel le générateur étant partagé par une fente circonférentielle, la partie supérieure est enlevée et une hotte est placée sur la partie inférieure. La hotte comporte une nacelle protégée pour loger les travailleurs et la nacelle est agrippée sur des outils pour couper en morceaux les tubes échangeurs de chaleur, et autres réactions internes et enlever les morceaux. La nacelle est abaissée dans le corps cylindrique au fur et à mesure de la progression du travail. Un courant d'air descendant est maintenu pour enlever toute particule radio-active en les éloignant de la nacelle. Cette méthode permet d'enlever l'intérieur d'un générateur de vapeur d'une enceinte à réacteur nucléaire sans exposer le personnel d'une radiation excessive. L'invention vise également les dispositions correspondantes. Application aux réacteurs nucléaires à eau pressurisée.
