The joint European testing program on HLW container materials

Within the framewark of the R and D program on Management and Storage of Radioactive Waste of the European Atomic Energy Community, one project is dedicated to the development of containers for vitrified high-level waste to be disposed of in geological formations. In particular, a joint testing program has been established for the assessment of the corrosion behavior of potential materials in the different disposal environments considered, respectively granite, salt and clay. As a result of previous screening tests on a number of materials, a detailed testing program is presently concentrated on three most promising reference materials, respectively Hastelloy C4, Ti-Pd (0.2%Pd) and a mild steel
