Abstract

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.
