Computational modeling study demonstrates radiation-induced corrosion dynamics in copper-coated fuel containers, highlighting accurate long-term safety predictions for nuclear repositories.
This paper presents the development and validation of a mixed‐potential model that couples a bulk radiolysis model to interfacial electrochemical reactions, enabling long‐term prediction of radiation‐induced corrosion of copper‐coated used fuel containers in a deep geological repository. Time‐dependent concentration profiles of molecular radiolysis products were compared between the bulk radiolysis model and the coupled model, highlighting the effects of interfacial reactions on bulk species evolution. Finally, the extent of corrosion from simulations was validated against experimental measurements, demonstrating the capability of the coupled approach to accurately reproduce observed corrosion behaviour on copper systems.
