[La corrosion des matériaux de conteneurs pour déchets HAVL – crédibilité scientifique de la prévision à long terme]
La résistance à la corrosion des matériaux de conteneur en situation de stockage est généralement prédite à partir de résultats d'expériences de durée limitée, courte à l'échelle des temps d'un stockage. La situation est illustrée pour deux classes de matériaux aux comportements bien typés et assez différents : les aciers non ou faiblement alliés, qui subiront une corrosion généralisée, et les matériaux passivables (aciers inoxydables ou alliages Ni–Cr–Mo), qui sont susceptibles de subir une corrosion par piqûres ou une corrosion caverneuse. Pour améliorer la crédibilité scientifique de la prévision à long terme et accroı̂tre la robustesse de la démonstration, il est nécessaire d'approfondir notre compréhension des mécanismes de la corrosion du conteneur couplée avec son champ proche. La tâche est vraisemblablement plus difficile pour les matériaux passivables que pour les matériaux dits consommables.
Traditionally, the corrosion behaviour of container materials can be predicted by extrapolation from relatively short-term experiments. Approaches to life prediction are described for two kinds of materials: carbon steel (corrosion allowance material) which must resist general corrosion, and passive materials (corrosion-resistant materials) which may suffer localized corrosion phenomena (pitting and crevice corrosion). The current theoretical and empirical basis for extrapolating the behavior of these materials to long periods emphasizes the significant gaps in understanding. To improve the credibility of life prediction, and to prove the robustness of geological disposal systems, predictive models based on mechanistic understanding are needed. This work is probably more difficult for the corrosion-resistant materials than for corrosion-allowance materials.
