Abstract

The objective of the project was to evaluate the potential and the limits of various non-destructive methods for testing the contents of 200 litre drums filled with radioactive waste. The following test problems were to be studied: (1) detection of free water on the surface of the waste matrix (concrete); (2) determination of the waste matrix level; (3) determination of internal gas pressure. The following methods were found to be suitable: For test problem (1): - measurement of Lamb wave attenuation, - acoustic impedance measurement (AIM) and - analysis of swash sound; For test problem (2): - acoustic impedance measurement (AIM) and - measurement of Lamb wave attenuation; For test problem (3): - a method of pressure compensation and - analysis of cover resonances after striking the cover. It was not possible to detect the concrete level by localisation of friction points using acoustic emission methods.
