Several OECD member countries agreed to establish the OECD/NEA Piping Failure Data Exchange Project (OECD/NEA OPDE) to encourage multilateral co-operation in the collection and analysis of data relating to degredation and failure of piping in nuclear power plants. The scope of data collection includes service-induced wall thinning, part through-wall cracks, through-wall cracks with and without active leakage and instances of significant degradation of piping pressure boundary integrity.
This final report describes the status of the OECD/NEA OPDE database after 9 years of operation (from May 2002-May 2009), and gives some insights based on approximately 3 800 failure events in the database.
