This book is designed to help for developing the general understanding of all the knowledge essential to ensure the reactor’s structural integrity. For this purpose, it not only explains basic knowledge of nuclear reactor structure engineering but also allows readers to learn how to systematize this knowledge as they study structural standards. This book first defines structural integrity and explains the concept of structural standards that is used for ensuring integrity, and then describes strength of materials (or mechanics of materials), which is vital as a means of designing components’ dimensions and other elements, and the finite element analysis, which has been developed on the basis of strength of materials and has been going mainstream in recent years. Subsequently, the book explains how components are designed, fabricated and examined in practice. In particular, with respect to design, the book places emphasis on what should be considered insizing of components, and provides a description of practical activities of sizing and other elements.

This book explores recent developments and advances in femtosecond beam science, making these more accessible through contributions from leaders in the field. Each contribution aims to make the particular area of femtosecond beam science accessible through explaining the particular field, reviewing recent advances worldwide, and featuring important results and possible future uses of femtosecond pulses in the field.Femtosecond beam science is expected to lead to the development of technology realizing dynamic microscopy, that is, the visualization of atomic motions, chemical reactions, protein dynamics and other microscopic dynamics. Advances have enabled the visualizations of phonons, thermal expansion and shock-wave propagation by advanced time-resolved X-ray diffraction, at a time resolution of 10 picoseconds. These achievements will extend to the development of femtosecond X-ray sources and fourth generation synchrotron light sources. Dynamic microscopy promises to be one of the most important issues in dynamic nanotechnology in the future. As a result, the overview of femtosecond beam science provided by this book will be useful.
