This textbook provides a comprehensive introduction to the physics of laser-plasma interactions (LPI), based on a graduate course taught by the author. The emphasis is on high-energy-density physics (HEDP) and inertial confinement fusion (ICF), with a comprehensive description of the propagation, absorption, nonlinear effects and parametric instabilities of high energy lasers in plasmas.The recent demonstration of a burning plasma on the verge of nuclear fusion ignition at the National Ignition Facility in Livermore, California, has marked the beginning of a new era of ICF and fusion research. These new developments make LPI more relevant than ever, and the resulting influx of new scientists necessitates new pedagogical material on the subject. In contrast to the classical textbooks on LPI, this book provides a complete description of all wave-coupling instabilities in unmagnetized plasmas in the kinetic as well as fluid pictures, and includes a comprehensive description of the optical smoothing techniques used on high-power lasers and their impact on laser-plasma instabilities. It summarizes all the key developments from the 1970s to the present day in view of the current state of LPI and ICF research; it provides a derivation of the key LPI metrics and formulas from first principles, and connects the theory to experimental observables.With exercises and plenty of illustrations, this book is ideal as a textbook for a course on laser-plasma interactions or as a supplementary text for graduate introductory plasma physics course. Students and researchers will also find it to be an invaluable reference and self-study resource.

For over 60 years, scientists and engineers have been trying to crack a seemingly intractable problem: how to build practical devices that exploit nuclear fusion. Access to electricity has facilitated a standard of living that was previously unimaginable, but as the world¿s population grows and developing nations increasingly reap the benefits of electrification, we face a serious global problem: burning fossil fuels currently produces about eighty percent of the world's energy, but it produces a greenhouse effect that traps outgoing infrared radiation and warms the planet, risking dire environmental consequences unless we reduce our fossil fuel consumption to near zero in the coming decades. Nuclear fusion, the energy-producing process in the sun and stars, could provide the answer: if it can be successfully harnessed here on Earth, it will produce electricity with near-zero CO2 byproduct by using the nuclei in water as its main fuel. The principles behind fusion are understood, but the technology is far from being fully realized, and governments, universities, and venture capitalists are pumping vast amounts of money into many ideas, some highly speculative, that could lead to functioning fusion reactors. This book puts all of these attempts together in one place, providing clear explanations for readers who are interested in new energy technologies, including those with no formal training in science or engineering. For each of the many approaches to fusion, the reader will learn who pioneered the approach, how the concept works in plain English, how experimental tests were engineered, the future prospects, and comparison with other approaches. From long-established fusion technologies to emerging and exotic methods, the reader will learn all about the idea that could eventually constitute the single greatest engineering advance in human history.

This book attempts to look into the genesis of security culture as a concept which emerged with the recognition of the role of the human factor in the context of security. It traces the rapid evolution of security culture into a multi-functional discipline reinforced by supplementary tools such as assessment and enhancement methodologies, reviews practical steps to harmonize nuclear safety and security culture as well as recommends its practical application to address insider threats and their consequences. In addition, it demonstrates how to tailor the generic model of nuclear security culture to meet specific needs of diverse facilities and activities in different countries. Finally, the book discusses several challenges which need to be addressed to make security culture a user-friendly, universal, and sustainable instrument to turn the perception of the human factor as a liability into an asset of nuclear security.

This book introduces novel approaches and practical examples of autonomous nuclear power plants that minimize operator intervention. Autonomous nuclear power plants with artificial intelligence presents a framework to enable nuclear power plants to autonomously operate and introduces artificial intelligence (AI) techniques to implement its functions. Although nuclear power plants are already highly automated to reduce human errors and guarantee the reliability of system operations, the term ¿autonomous¿ is still not popular because AI techniques are regarded as less proven technologies. However, the use of AI techniques and the autonomous operation seems unavoidable because of their great advantages, especially, in advanced reactors and small modular reactors.The book includes the following topics:Monitoring, diagnosis, and prediction.Intelligent control.Operator support systems.Operator-autonomous system interaction.Integrationinto the autonomous operation system. This book will provides useful information for researchers and students who are interested in applying AI techniques in the fields of nuclear as well as other industries. This book covers broad practical applications of AI techniques from the classical fault diagnosis to more recent autonomous control. In addition, specific techniques and modelling examples are expected to be very informative to the beginners in the AI studies.

The war in Ukraine, with the exposure of nuclear power stations and the danger of atomic warfare, has made the legacy of the Soviet nuclear sector of critical importance. The two authors map the Soviet nuclear industry in a shifting historical context, making sense of a complex socio-technical and environmental history. Taking an innovative approach, this book explores the history of atomic power in the former Soviet Union using the spatial dimensions of the nuclear industry as a point of departure. The key concept is that of the archipelago - a network of nuclear facilities spread throughout the Soviet territory, but mutually reliant on each other and densely connected. The story traces the emergence of nuclear science and technology for military and civilian purposes through to the post-Soviet Russian nuclear corporations as providers of resources and technology. The book explains how nuclear developments in the Soviet Union interacted with processes of environmental and landscape change. The spatial lens offers an analytically fruitful and pedagogically stimulating way to comprehend the nuclear histories of the Soviet Union and its successor states.
