Cel The objective of the project was to evaluate the potential and the limits of various nondestructive methods for testing the contents of 200 l drums filled with radioactive waste. The following test problems were to be studied: detection of free water on the surface of the waste matrix (concrete); determination of the waste matrix level; determination of internal gas pressure.The following methods were found to be suitable. For detection of free water: measurement of Lamb wave attenuation; acoustic impedance measurement (AIM); and analysis of swash sound. For determination of the waste matrix level: acoustic impedance measurement (AIM); and measurement of Lamb wave attenuation. For determination of internal gas pressure: a method of pressure compensation; and analysis of cover resonances after striking the cover. It was not possible, however, to detect the concrete level by localization of friction points using acoustic emission methods.
