Potential for Stress Corrosion Cracking of Copper Containers in a CanadianNuclear Fuel Waste Disposal Vault (Possibilite de Fissuration par Corrosion sous Contrainte des Conteneurs en Cuivre dans une Installation de Stockage Permanent des Dechets de Combu

摘要

The potential for stress corrosion cracking (SCC) of copper nuclear fuel wastecontainers in a conceptual Canadian disposal vault has been assessed through a review of the literature and comparison of those environmental factors that cause SCC with the expected disposal environment. Stress-corrosion cracking appears to be an unlikely failure mode for Cu containers in a Canadian disposal vault because of a combination of environmental factors. Detailed reviews of the SCC literature are presented as Appendices.
