OSTI ID:491867
Concrete decontamination from organics, metals, and radionuclides requires removal of up to one inch of the surface layer. The Electro- Hydraulic Scabbling (EHS) technique has been developed within a 3- phase program. A prototype 8 kW EHS unit was designed and assembled in Phase II. This system was tested initially by scabbling noncontaminated concrete, and later at the DOE Fernald site where a concrete floor containing uranium was decontaminated. In the latter test, the unit operated without problems and reduced the counts per minute by more than 90%. Currently in Phase III, a larger 30 kW unit has been assembled and prepared for testing/demonstration.
