ABSTRACT:
Apparatus and method for remotely decontaminating, cleaning, scrubbing or polishing the surface of a nuclear reactor cavity wall. The apparatus includes brushes for scrubbing the surface and a drive mechanism for rotating the brushes. The drive mechanism may be a gear drive, a chain and sprocket drive, or a belt and pulley drive. Connected to the brushes and enclosing the drive mechanism is an sealable enclosure. A drive axle extends from the drive mechanism to a motor which is disposed in a housing connected to and located proximate the enclosure. The motor is capable of rotating the drive axle which in turn operates the drive mechanism for rotating the brushes. A fluid dispenser is also provided for dispensing a cleaning agent against the surface to enhance the cleaning ability of the brushes. A container is attached to the housing for receiving ballast therein so that the brushes may exert a bearing pressure against the surface of the wall for suitably scrubbing the surface. Connected to the housing are lifting lugs for receiving lift cables which are connected to an overhead crane. The overhead crane is used to raise and lower the apparatus and to horizontally position the apparatus along the surface of the wall to be decontaminated.
