Abstract

The Supercontainer is the Belgian reference concept for the packaging of vitrified high-level radioactive waste (HLW) and spent fuel. In a previous test performed to evaluate its construction feasibility, micro-cracks developed on the surface of the concrete buffer. The surficial nature of the micro-cracks should neither jeopardize the functionality nor the safety of the Supercontainer. However, through-going cracks should be avoided as they can create preferential pathways for the migration of aggressive species. This paper presents the results of a test performed to evaluate the suitability of using Digital Image Correlation (DIC) to detect the onset of micro-cracking in the concrete buffer. Preliminary tests showed that the DIC method can measure micro-cracks with a crack opening resolution of approximately 12.5 microns, which is sufficiently small to detect the formation of potential micro-cracks in the concrete buffer of the Supercontainer.
