Device for volume delimitation during work with contaminated parts
First Claim
1. A device for volume delimitation when working with radioactively contaminated parts within the device, such as a control rod for a nuclear power plant for preventing contamination of a total volume of liquid medium surrounding the device and forming a pool, such as a nuclear reactor pool, said device comprising a transportable tank with a substantially horizontal bottom part and with substantial vertical side walls and an open top, means within the tank connectable with cleaning equipment for the cleaning of liquid medium delimited within the tank, wherein at least the side walls are foldable and are comprised of a material of synthetic fibers of a strength resistant to puncture, the material comprising polyethylene.

Abstract
The invention relates to a volume delimitation tank (1) for preventing or limiting contamination of the surrounding liquid medium when working with contaminated parts. The volume delimitation tank (1) comprises a sack or channel which constitutes at least the substantially vertical walls (1a-d) of the tank and is made of a material which is capable of being folded, which is radiation-resistant, and resistant to puncture. The walls (1a-d) can be provided with fold notches (27) to obtain a well-defined folding when, for example, lowering at least one wall portion (1a-d) for passing objects out of the tank (1). The walls (1a-d) of the tank (1) are arranged at a bottom part (9). Cleaning equipment (16) is arranged inside the tank (1) for continuous cleaning of the contained volume.
