Summary: This study conducted thermodynamic calculations using the PHREEQC software to select a suitable database for evaluating repository performance, with a focus on activity coefficient models. The assessment of chloride-assisted corrosion revealed varying copper solubilities under different mass transport scenarios.

Summary: The copper sulfide model has been extended to simulate microbial reduction of sulfate in a repository, considering processes such as Monod kinetics, organotrophic and chemotrophic sulfate reduction, and dissolution of solid organic matter and gypsum. Results indicate that siderite dissolution and the precipitation of microbially produced sulfide as mackinawite are important processes in the repository environment.

Summary: A probabilistic pitting model is developed for predicting perforation corrosion probabilities in water-saturated bentonite under aerobic conditions. The model indicates that environments under passive conditions may lead to pitting in the first few years, primarily influenced by oxygen availability.

Summary: This paper presents the development of a mixed-potential model that combines the anodic dissolution of copper with the oxidation and reduction of radiolysis products, enabling the long-term prediction of radiation-induced corrosion of copper. The overall conceptual model is described, followed by a detailed discussion on the use of COMSOL software to predict bulk radiolysis behavior. Several validation methods, including comparison with short-term experimental data, are employed to validate the COMSOL model. The underlying principles, assumptions, and validation results are presented.

Summary: Posiva Oy has applied for an operating license in Finland to dispose of spent fuel in a deep geological repository. The application is based on decades of research and development by experts from Finland, Sweden, and internationally. This paper discusses the corrosion performance of the canister in the long-term safety case, emphasizing the importance of relating laboratory observations to expected environmental conditions and using complementary models to improve long-term predictions. Examples of canister lifetime predictions for different scenarios and climate conditions are provided.

Summary: Natural and archaeological analogues are useful for predicting long-term corrosion in nuclear waste systems, providing confidence to experts and lay audiences. These analogues demonstrate both the expected and unexpected corrosion processes for copper and steel fuel containers under repository conditions. The concept of kinetic versus thermodynamic stability explains the persistence of such analogues and supports long-term corrosion performance predictions.
