Several OECD member countries agreed to establish the OECD/NEA Piping Failure Data Exchange Project (OPDE) to encourage multilateral co-operation in the collection and analysis of data relating to degration and failure of piping in nuclear power plants. The scope of the 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. The project was formally launched in May 2002 under the auspices of the OECD/NEA.

This report describes the status of the OECD/NEA OPDE database after six years of operation from 2002-2008, and gives some insights based on approximately 3 600 piping failure events in the database.
