摘要

The oxide morphology of films on fuel cladding undergoing enhanced corrosion in BR3 is compared with laboratory observations of degradation of zirconium oxide films in concentrated LiOH solutions. It is concluded that such an LiOH concentration process could have caused the enhanced corrosion in BR3. This probably was initiated by crud deposition raising the surface temperature of the cladding above the saturation temperature during the first cycle of operation in BR3.
