There is a current trend for the operational life of nuclear power plants to be extended beyond that of their original licence period. This publication is the proceedings of the third International Conference on Nuclear Power Plant Life Management, which demonstrated the value of an open exchange of information between experts from different countries and organizations. The presentations cover a wide range of subjects including: very specific solutions for reactor pressure vessel integrity; material degradation; ageing management and licensing renewal approaches; risk informed inspection; non-destructive examination methods; and tools to be used in various stages of plant life management programmes. The publication provides utilities, operators and regulators with a comprehensive state of the science and technology overview of the main issues concerning nuclear power plant life management.
