Title: (DE) VORRICHTUNG ZUM ABBRECHEN EINER REAKTORSTRAHLENSCHUTZWAND.
(EN) REACTOR SHIELDING WALL DISMANTLING APPARATUS
(FR) DISPOSITIF DE DEPOSE DE LA PAROI DE BLINDAGE D'UN REACTEUR.
Abstract: front page image
(EN) Reactor shielding wall dismantling apparatus provided with a support (2) disposed in such a manner as to extend from the upper portion of a reactor to its bottom, an upper support means (3) for supporting the upper part of this support (2) at the upper portion of the reactor, and cutting means (5, 6) disposed vertically movably on the support (2). The support (2) is rotatably supported by the support means (3). The support means (3) is further provided with a rotating means (30, 31, 32) for rotating the support (2). Thus, when the support (2) is rotated, the cutting means (5, 6) can be rotated inside the reactor. Since the rotating means is disposed on the upper portion of the reactor, its maintenance and inspection is easy.
(FR) Dispositif de dépose de la paroi de blindage d'un réacteur, pourvu d'un support (2) disposé de manière à s'étendre de la partie supérieure d'un réacteur jusqu'à la partie inférieure, d'un organe de support supérieur (3) supportant la partie supérieure du support (2) dans la partie supérieure du réacteur, et d'un organe de coupe (5, 6) mobile et disposé verticalement sur le support (2). Le support (2) est supporté par l'organe de support (3) de manière à pouvoir tourner. L'organe du support (3) est en outre pourvu d'un organe rotatif (30, 31, 32) permettant la rotation du support (2). Par conséquent lorsque le support (2) tourne, l'organe de coupe (5, 6) peut tourner à l'intérieur du réacteur. Etant donné que l'organe rotatif est disposé sur la partie supérieure du réacteur, la maintenance et l'inspection sont aisées.
