The objective of this Safety Report is to provide information on the implementation of IAEA Safety Standards Series SSG-48, to support the ageing management and preparation for the safe, long-term operation of a nuclear power plant. It addresses ageing management of active and passive structures and components for water moderated reactors that can have an effect, directly or indirectly, on the safe operation of the plant and that are susceptible to ageing. This publication is intended for ageing management and long-term operation specialists as well as nuclear power plant managers, regulatory bodies and technical support organizations.
