When nuclear power plants reach the end of their nominal design life, they undergo a special safety review and an ageing assessment of their essential structures, systems and components for the purpose of validating or renewing their licence to operate for terms beyond the service period originally intended. Three different plant life management models have been used to qualify these nuclear power plants to operate beyond their original design life. This publication presents a collection of sample licensing practices for long term operation among IAEA Member States. The various plant life management models used to obtain long term operation authorizations are described and comparisons drawn against the standard periodic safety review model. Lessons learned and warnings about possible complications and pitfalls are also described to minimize the licensing risk during operation and future long term operation applications. The main intention of this publication is to support nuclear power plant owners and operators planning an extension of plant operation beyond its original design life, but it also serves as a useful guide for those interested in procuring, from the beginning, the necessary tools to implement ageing management in their future plant with long term operation in mind.

Plant life management (PLiM) is a methodology focussed on the safety-first management of nuclear power plants over their entire lifetime. It incorporates and builds upon the usual periodic safety reviews and licence renewals as part of an overall framework designed to assist plant operators and regulators in assessing the operating conditions of a nuclear power plant, and establishing the technical and economic requirements for safe, long-term operation. Understanding and mitigating ageing in nuclear power plants critically reviews the fundamental ageing-degradation mechanisms of materials used in nuclear power plant structures, systems and components (SSC), along with their relevant analysis and mitigation paths, as well as reactor-type specific PLiM practices. Obsolescence and other less obvious ageing-related aspects in nuclear power plant operation are also examined in depth. Part one introduces the reader to the role of nuclear power in the global energy mix, and the importance and relevance of plant life management for the safety regulation and economics of nuclear power plants. Key ageing degradation mechanisms and their effects in nuclear power plant systems, structures and components are reviewed in part two, along with routes taken to characterise and analyse the ageing of materials and to mitigate or eliminate ageing degradation effects. Part three reviews analysis, monitoring and modelling techniques applicable to the study of nuclear power plant materials, as well as the application of advanced systems, structures and components in nuclear power plants. Finally, Part IV reviews the particular ageing degradation issues, plant designs, and application of plant life management (PLiM) practices in a range of commercial nuclear reactor types. With its distinguished international team of contributors, Understanding and mitigating ageing in nuclear power plants is a standard reference for all nuclear plant designers, operators, and nuclear safety and materials professionals and researchers. Introduces the reader to the role of nuclear power in the global energy mix Reviews the fundamental ageing-degradation mechanisms of materials used in nuclear power plant structures, systems and components (SSC) Examines topics including elimination of ageing effects, plant design, and the application of plant life management (PLiM) practices in a range of commercial nuclear reactor types

This publication provides an overview of the various plant life management (PLiM) methodologies, technologies and processes to ensure long term operation of heavy water reactors (HWRs). Implementation of a systematic and comprehensive PLiM programme, such as that outlined in the publication, goes a long way towards meeting the overall goal of HWR owners and operators to successfully achieve design life and continued operation. Included in this publication are technical aspects of HWR PLiM, component specific technology considerations for condition assessment, an example of a proactive ageing management programme, and Ontario power generation experiences. Country reports from Argentina, Canada, India, the Republic of Korea and Romania are attached in an annex in order to share practices and experiences of PLiM programmes.

This report explains the general approach to plant life management (PLiM), shows and defines the relationship between nuclear power plant maintenance and PLiM, assembles a list of good practices and formulates guidelines for ageing management of critical structures, systems and components. Additionally, the issues of PLiM for long term operation are discussed in terms of human, technological, economic and regulatory aspects, as well as the importance of the exchange of information regarding lessons learned. PLiM is not only a technical system but is also an attitude of the owners to retain plants in operation as long as possible from a safety and business point of view. Asset management is thus a significant parameter and driving force for PLiM implementation.--Publisher's description.

A plant life management (PLiM) programme is an effective tool that allows an operator to manage ageing effects in structures, systems and components (SSCs) for long term operation of nuclear power plants. Such a programme helps facilitate decisions concerning when and how to repair, replace or modify SSCs in an economically optimized way, while assuring that the highest levels of safety are maintained. This publication is the proceedings of the fourth in a series of international conferences convened by the IAEA on nuclear power plant life management. The conference provided a forum for information exchange on national and international policies, as well as on regulatory practices, and for the demonstration of strategies, including their application in ageing management and PLiM programmes for operating and new nuclear power plants. The proceedings include the opening address, presentations of the keynote speakers, summaries of the individual technical sessions, and conclusions and recommendations of the chairperson of the conference.
