SCCODRA - Development of an innovative corrosion monitoring methodology for the French radioactive waste disposal application
Résumé
SCCoDRa is an industrial research project which aims to develop characterization and monitoring tools in the perspective of the monitoring program dedicated to the Industrial Centre for Geological Disposal (Cigeo). It has two objectives:
* to screen and develop a potential candidate of a nondestructive testing (NDT) technique (contactless) on metal containers for radioactive waste in order to verify their integrity simply, quickly, reliably, and precisely upon reception at the disposal facility (in the case of ILW-LL). Such a technique must therefore assess the containers for corrosion by means of complete though-thickness mapping.
* to develop one possible methodology for monitoring corrosion in certain metal structures within the facility over time. In particular, this applies to the steel tubes (sleeves) placed inside the micro-tunnels for HLW ("HLW disposal cells"). Here also, the methodology should be based on innovative technology developed in the areas of NDT, electrochemistry, and electrical techniques. In this paper, we will focus on this second part of the project to present the progress of work relating to guided waves and MURE probe to detect and characterize corrosion on the metal lining.
