Abstract

Engineered barrier for HLW repository is composed of the waste form, the canister and the buffer/backfill material. Assessment of the applicability of metal as candidate materials of canister for HLW has been conducted in some countries. Many bronze relics from the XiZhou Dynasty, China, dated from more than 3,000 years ago, have been preserved perfectly. The study on the corrosion of the bronze relics could contribute to the material selection and design of canisters for HLW. The corrosion products of ancient bronzes consist of copper carbonate hydrate, lead carbonate, copper oxides etc. The corrosion mechanism of the substrate was mainly characterized by electrochemical corrosion, whereas the corrosion mechanism of surface layers was characterized by direct chemical corrosion and electrochemical corrosion.
