DETERMINATION AND CONTROL OF ACTIVITY IN RADIOACTIVE WASTE AS PART OF PRODUCT CONTROL

Objective


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.
