Enhanced Ultrasonic Decontamination

Category: Decontamination > Surface Cleaning > Ultrasonic Cleaning
Reference # : Model No :

Sellafield Ltd has examined the use of ultrasonics to aid decontamination on several occasions from 1970-1990’s. These have been reliant upon immersion of items in a liquid to be effective. The University of Southampton have created a device that makes ultrasonic decontamination achievable in localized areas and without total immersion. They have further shown its potential for porous materials against a range of fouling media. The work undertaken is the first stage of proving concept and understanding the applicability for potential deployment at Sellafield. A range of substrates were investigated, including steels, concrete and polymers used in glove boxes to remove sludges, entrained powders and particulates. An example of the intended future use would be to extend the use of Hypalon gloves by decontaminating them to avoid hand/extremity dose uptake. Some emphasis is given to this area due to the current supply issues with gloves. Furthermore, as a low liquid volume recirculating process, it has potential use in glove boxes.
