The Integrity and Aging of Components and Structures Working Group (IAGE) of the Organisation for Economic Cooperation and Development (OECD)/Nuclear Energy Agency (NEA) was established under the Committee on the Safety of Nuclear Installations (CSNI) for three reasons: (i) to advance the current understanding of those aspects relevant to ensuring the integrity of structures, systems, and components ; (ii) to provide for guidance in choosing the optimal ways to handle challenges to the integrity of operating as well as new nuclear power plants, and (iii) to take an integrated approach to design, safety, and nuclear power plant life management. The group operates through annual plenary meetings and technical workshops and by issuing state-of-the-art reports and topical opinion papers. This paper details some recent IAGE activities and products, focusing on those dealing with the degradationmechanisms of metal and concrete components.
