This publication presents the results of the Coordinated Research Project, “Ageing Management Programmes for Dry Storage Systems”, which brought together organisations from seven countries and ran from 2016 to 2021. It provides an overview of the methodologies for developing ageing management programmes for the different dry storage systems used for the storage of spent fuel, as well as national regulatory requirements in this field. It also examines the operating experience from participating countries with different systems, technologies to support monitoring, mitigation and repair, and guidance on how ageing management programmes should be updated.
