Description of FEP Effects
Identification of corrosion products, including the development of passivating layers, is important in assessing the possible wider effects on EBS performance of corrosion. For example, the formation of magnetite as the overpack corrodes could influence the dissolution rate of the waste and/or the migration of radiolytic oxidants formed near the waste surface, as well as chemical conditions in the buffer porewater. Supercontainer envelope corrosion products may affect chemical conditions in the buffer porewater.
