A large variety of spent fuels from research reactors around the world are currently stored underwater in basins. Most of this fuel is clad in aluminium based alloys that are susceptible to corrosion in water. Studies have shown that the important problem of localized corrosion is a very complex phenomenon and difficult to predict. This publication documents a study of corrosion mechanisms and corrosion control on all types of aluminium clad research reactor spent fuel stored in water. It will contribute to the understanding of localized corrosion and serve as guidance to those faced with extending the interim wet storage of research reactor spent fuel.
