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.
Both discrete and continuous descriptions are developed. Finally, three-dimensional dislocation configurations are discussed, including the cross slip, kinks, and dislocation junctions.
Chapter 9 focuses on two-dimensional wall defects surfaces, stacking faults, grain boundaries and serves as the basis for the consideration of microstructures within materials. The author highlights their role in producing confinement in the context of elastic waves, mass transport, and plastic action.
The notion of an interfacial energy and that of a surface reconstruction are defined and exemplified in a number of representative cases. Chapter 10 analyzes some types of microstructures that exist in materials. First, the author discusses a considerable diversity of microstructures and a possibility of their production by appropriate processing strategies, and what the consequences of such microstructures are to the underlying physical properties of a material.
The solution the Eshelby inclusion problem is derived and used in investigating the equilibrium morphologies of second phase particles. Also, the issue of temporal evolution of two-phase microstructures has been considered. Special attention is given to the realization of the compatibility condition in the context of martensitic microstructures.
In the consideration of grain growth in polycrystals, the author has made use of the Potts model, phase field models, and sharp interface models. Part IV, Facing the Multiscale Challenge of Real Material Behavior , constitutes the culmination of preceded developments discussed in the book with the aim to build effective theories based on a reduced set of degrees of freedom.
Chapter 11 concerns a mutual interplay between the different types of defects defined earlier. Three groups of problems are considered: diffusion, mass transport assisted deformation, and dis-location-grain boundary interaction. In particular, these include exchange mechanisms for surface diffusion, Nabarro-Herring and Coble mechanisms for creep and the Rice model of dislocation nucleation at acrack tip, and the phenomenon of hardening approached from various perspectives.
Chapter 12 is a crowning part of the book, being explicitly devoted to the problem of bridging scales and effective theory construction. Here, Phillips revisits his previous considerations and generalizes the philosophy behind multi-scale modeling.
Indicating to a tradition of multiscale approach, the author records some historic examples of multiscale modeling. He discusses cohesive surface models and mixed approaches in which constitutive models of different sophistication hierarchical structure are used, eg, a conventional continuum model in a region far from defects cracks, dislocations , whereas in the immediate vicinity of defects a more refined analysis pertinent to subscales.
In the format of gradient flow dynamics, variational derivations of the Allen-Cahn equation which describes the spatio-temporal evolution of a non-conserved order parameter field, and the Cahn-Hillard equation for such evolution of conserved fields are obtained. He shows how to create a family of effective Hamiltonians by the renormalization procedure and indicates the Monte Carlo method and hyperdynamics methods as a scheme for the hierarchical treatment of diffusive processes, raising the question on how to connect the notion of temperature and time.
Phase field models are invoked in the context of both solidification and phase separation, and the finite element interpolation and its consequences in elimination of atomic degrees of freedom. Finally, in Chapter 13, the author has collected his reflections on the universality and specificity in materials and posed a series of intriguing open questions. The presentation of this difficult and complex subject matter is organized in an accessible and attractive fashion, being pedagogically well balanced as concerns both the level of detail discussed and the notations used.
It contains a lot of enlightening descriptions of the current theoretical concepts and many case studies. The included graphical illustrations of numerical results and of experimental findings substantiate the theoretical constructs and, in addition to that, will be provocative to the perspicacious reader.
Each chapter closes with a useful section, Further Reading , and a set of problems to solve, which are related to the topics discussed in that chapter. There is a single list of references and a subject index at the end of the book. A careful reading of the entire book shows that the text is well edited; this reviewer spotted only a few misprints.
The various chapters can be read independently, but the logic of the book is intertwined, so in order to better appreciate the message conveyed the book should be treated as a single entity. Phillips has undertaken a very difficult and venturesome enterprise to write a book that encompasses such a wide spectrum of different concepts and issues under one roof.
This reviewer believes that the value of this book is in that, on the one hand, it substantiates the need for a multiscale approach and, on the other hand, presents a framework for a mechanism of the information passage from the microscopic scales to those associated with macroscopic observables.

Kjems, J. Abstract Abstract. Recent results of diffraction studies of texture, residual stresses, and foreign phases are reviewed. An example of Huang scattering due to thermal disorder is mentioned, and the use of this technique is advocated in combination with diffuse and small angle scattering for the study of phase separation and segregation.
Finally, the results are summarized of extensive studies of the thermally induced disorder in the fluorites using coherent and incoherent quasielastic scattering as well as single-crystal diffraction.
