Development of the tools and interpretation techniques for ultrasonic surveys to monitor the rock barrier around radioactive waste packages in geological repositories OMNIBUS, Final report

Project ID: FIKW-CT-2001-00202
Funded under: FP5-EAECTP C

Abstract

The overall objective of the OMNIBUS project was to develop operational hardware and software technology that can be used to monitor the rock barrier at potential geological radioactive waste disposal sites. The project has involved two main aims. The first aim includes the design and construction of a down-hole tool that can be deployed in a variety of field situations so as to collect ultrasonic data at both hard-rock (e.g. granite) and soft-rock (e.g. argillite) sites. The tool development has involved hardware and software components as well as a field test. The second aim of the project has involved developing new methodologies for processing and interpreting ultrasonic survey data collected by the tool. To maximise the potential for this technology it is important that the data can be interpreted in terms of useful engineering parameters that provide information on the stability of a given rock mass, such as the location, severity and extent of induced crack damage. The project has aimed to address these issues through a series of laboratory, in situ and numerical modelling experiments.
