Long-term performance of candidate materials for HLW / spent fuel disposal containers

Objectif

The proposal addresses the qualification of corrosion resistant materials for long- lived HLW/Spent Fuel disposal containers. Such containers as a component of the multi-barrier system will improve the safety in the disposal in geological formations. Based on the findings and recommendations of the previous EU-project the corrosion studies will be concentrated on the most promising container materials such as carbon steel, stainless steels, Ti99.8-Pd Hastelloy and Cu-Ni alloys.

The project will include corrosion studies in rock salt, granite and clay environments. The work will consist of:
(i) long-term immersion tests to determine the final corrosion rate of the materials and their susceptibility to local corrosion;
(ii) electrochemical studies to examine the corrosion mechanisms and the influence of various parameters on corrosion;
(iii) slow strain rate tests to examine the stability of the materials to stress corrosion cracking.
