CA 2084503

When cleaning contaminated surfaces of components of nuclear plant, it is important to avoid the release of radioactive aerosols into the atmosphere and to limit the amount of radioactive waste arising. The invention therefore proposes a mechanical process, using a blast-cleaning agent (4), in which the area (2) to be decontaminated is surrounded, during treatment with the jet, by a dust-tight enclosure (10) and a closed-circuit jet unit (70) is used to recycle the blast-cleaning agent. In addition, the invention includes a device for carrying out the dry decontamination process. In a preferred embodiment, this device includes a manipulator with a jet-nozzle mounted so that it can move on a hollow guide rail through which the dry-agent/dust mixture (6) produced is evacuated.

Enter Lorsqu'on nettoie des surfaces contaminées de composants d'une centrale nucléaire, il est important d'éviter de libérer des aérosols radioactifs dans l'atmosphère et de limiter la quantité de déchets radioactifs produits. La présente invention propose un procédé mécanique comportant l'utilisation d'un agent de décapage au jet (4) selon lequel la zone (2) à décontaminer est entourée, durant le traitement au jet, d'une enveloppe étanche aux poussières (10). Une unité de jet en circuit fermé (70) est utilisée pour recycler l'agent de décapage au jet. En outre, l'invention comprend un dispositif permettant d'entreprendre le procédé de décontamination à sec. Selon un modèle préféré, le dispositif comprend un manipulateur sur lequel est montée une tuyère d'éjection, pour se déplacer sur un rail-guide creux, par laquelle le mélange agent sec-poussières (6) produit est évacué.
