X-Ray, Digital Imaging with Volumetric Density Measurement and Profiling, Applied to the Characterization of Waste Drums

The European Commission's Joint Research Centre Ispra Site (JRC-Ispra) has initiated a decommissioning and waste management program that will span about two decades. The program includes a requirement to characterize the contents of about 6,500 radioactive, 220 litre waste drums whose documented history is incomplete. To render the characterization process more efficient, the drums will be initially divided into homogeneous groups, an activity that will be based on existing documentation and non-destructive examination (NDE) by X-ray digital imaging. This paper describes the X-ray imaging techniques chosen, and the planned performance validation of the equipment. (authors)
