Uses of x-ray radiographic and tomographic methods for nondestructive evaluation (NDE) of waste
- Idaho National Engineering Lab., Idaho Falls, ID (United States)
Recent advances in radiographic and tomographic hardware, digital processing hardware, image processing and analysis software, coupled with applications of long-standing inspection methods used in other applications (medical and industrial) may enhance the ability for inspection agents and radiography operators to determine and quantify container contents. The majority of development work in the area of radiographic and tomographic waste inspection to date has emphasized only hardware development of the source and detector, and image display. As the volume of data and data quality improves, new methods of handling and interpreting the information must be developed. This paper will present a summary of recent developments in x-ray radiographic and tomographic methods for waste container inspection and emphasize the use of data derived from these methods to improve interpretations for nondestructive evaluation (NDE) and nondestructive assay (NDA). The emphasis will be on transuranic and mixed wastes from the DOE complex including 55-gallon drums, boxes of various sizes, and conveyor systems. Following a brief survey of developments throughout the waste inspection community, we will describe several recent efforts at the Idaho National Engineering Laboratory (INEL) to advance the state of the art in waste inspection through x-ray imaging. Real time digital image enhancements to analog RTR images, digital acquisition and processing of single digital radiographic projection images, identification and quantification of materials, enhanced image display techniques, and rapid tomographic data acquisition will be presented.
