This publication presents a comprehensive summary of the technical work carried out under an IAEA coordinated research project and provides an overview of Member States' approaches to mitigating challenges that are encountered in achieving reliability, sustainability and safety with advanced pressurized heavy water reactor (PHWR) fuels. These challenges, which were discussed and analysed by the project participants, include fuel performance degradation, insufficient availability of operating experience at high burnup and margin erosion by ageing.
