Abstract

An IAEA Technical Committee meeting recommended that tests concerning the disposal of high-level radioactive waste should be performed in realistic environments corresponding to normal and accidental conditions, in order to qualify and apply corrosion monitoring techniques for corrosion evaluation under real repository conditions, and to develop corrosion and near-field evolution models. The Belgian experimental programme for the qualification of a container for long-term HLW storage in clay formations complies with these recommendations. The emphasis in the programme is on in situ corrosion testing and monitoring and in situ control of the near-field chemistry. Initial field experiments were performed in a near-surface clay quarry at Terhaegen. Three reference materials were chosen for extensive in situ overpack testing. Ti/0.2 Pd and Hastelloy C-4 were chosen as reference corrosion resistant materials, and a low-carbon steel as a corrosion allowance reference material. This report summarises progress made in the material qualification programme since 1983-84.
