IAEA publications on Integrity of Reactor Pressure Vessels (RPV)
The IAEA has established an International Working Group on Lifetime Management of NPPs and conducted a series of IAEA Co-ordinated Research Projects (CRPs) as well as created a worldwide database to store the results from RPV surveillance programmes. The primary purpose shall be to collect all accessible data from these programmes and specimens and then perform a more general analysis of these results than can be performed using national (or utility) databases, only. Creation of the database started in 1996 under the coordination of the aforementioned International Working Group on Lifetime Management of Nuclear Power Plants. To date, results from surveillance programmes from 10 countries are included in this database. Access to the databases is controlled by agreements with the IAEA.
