'Absolutely stunning. . . a formidable achievement. A six-part historical thriller that is essential reading for both our politicians and the ordinary citizen' Kai BirdBest-selling historian Serhii Plokhy returns with an illuminating exploration of the atomic age through the history of six nuclear disasters In 2011, a 43-foot-high tsunami crashed into a nuclear power plant in Fukushima, Japan. In the following days, explosions would rip buildings apart, three reactors would go into nuclear meltdown, and the surrounding area would be swamped in radioactive water. It is now considered one of the costliest nuclear disasters ever. But Fukushima was not the first, and it was not the worst. . . In Atoms and Ashes, acclaimed historian Serhii Plokhy tells the tale of the six nuclear disasters that shook the world: Bikini Atoll, Kyshtym, Windscale, Three Mile Island, Chernobyl and Fukushima. Based on wide-ranging research and witness testimony, Plokhy traces the arc of each crisis, exploring in depth the confused decision-making on the ground and the panicked responses of governments to contain the crises and often cover up the scale of the catastrophe. As the world increasingly looks to renewable and alternative sources of energy, Plokhy lucidly argues that the atomic risk must be understood in explicit terms, but also that these calamities reveal a fundamental truth about our relationship with nuclear technology: that the thirst for power and energy has always trumped safety and the cost for future generations.

This SpringerBrief presents a brief introduction to probabilistic risk assessment (PRA), followed by a discussion of abnormal event detection techniques in industrial control systems (ICS). It also provides an introduction to the use of game theory for the development of cyber-attack response models and a discussion on the experimental testbeds used for ICS cyber security research. The probabilistic risk assessment framework used by the nuclear industry provides a valid framework to understand the impacts of cyber-attacks in the physical world. An introduction to the PRA techniques such as fault trees, and event trees is provided along with a discussion on different levels of PRA and the application of PRA techniques in the context of cybersecurity. A discussion on machine learning based fault detection and diagnosis (FDD) methods and cyber-attack detection methods for industrial control systems are introduced in this book as well.A dynamic Bayesian networks based method that can be used to detect an abnormal event and classify it as either a component fault induced safety event or a cyber-attack is discussed. An introduction to the stochastic game formulation of the attacker-defender interaction in the context of cyber-attacks on industrial control systems to compute optimal response strategies is presented. Besides supporting cyber-attack response, the analysis based on the game model also supports the behavioral study of the defender and the attacker during a cyber-attack, and the results can then be used to analyze the risk to the system caused by a cyber-attack. A brief review of the current state of experimental testbeds used in ICS cybersecurity research and a comparison of the structures of various testbeds and the attack scenarios supported by those testbeds is included. A description of a testbed for nuclear power applications, followed by a discussion on the design of experiments that can be carried out on the testbed and the associated results is covered as well.This SpringerBrief  is a useful resource tool for researchers working in the areas of cyber security for industrial control systems, energy systems and cyber physical systems. Advanced-level students that study these topics will also find this SpringerBrief useful as a study guide.

Calculation exercises are provided, and a Bibliography lists authoritative print and online sources of information for readers who wish to pursue more detailed study of this fascinating topic.

This book looks at the early history of nuclear power, at what happened next, and at its longer-term prospects. The main question is: can nuclear power overcome the problems that have emerged? It was once touted as the ultimate energy source, freeing mankind from reliance on dirty, expensive fossil energy. Sixty years on, nuclear only supplies around 11.5% of global energy and is being challenged by cheaper energy options. While the costs of renewable sources, like wind and solar, are falling rapidly, nuclear costs have remained stubbornly high. Its development has also been slowed by a range of other problems, including a spate of major accidents, security concerns and the as yet unresolved issue of what to do with the wastes that it produces. In response, a new generation of nuclear reactors is being developed, many of them actually revised versions of the ideas first looked at in the earlier phase. Will this new generation of reactors bring nuclear energy to the forefront of energy production in the future?

Drone warfare has raised profound ethical and constitutional questions both in the halls of Congress and among the U.S. public. Not since debates over nuclear warfare has American military strategy been the subject of discussion in living rooms, classrooms, and houses of worship. Yet as this groundbreaking new work shows, the full implications of drones have barely been addressed in the media.In a unique take on a subject that has grabbed headlines and is consuming billions of taxpayer dollars each year, philosopher Grégoire Chamayou applies the lens of philosophy to our understanding of how drones are changing our world. For the first time in history, a state has claimed the right to wage war across a mobile battlefield that potentially spans the globe. Remote-control flying weapons, he argues, take us well beyond even George W. Bush's justification for the war on terror.What we are seeing is a fundamental transformation of the laws of war that have defined military conflict as between combatants. As more and more drones are launched into battle, war now has the potential to transform into a realm of secretive, targeted assassinations of individuals—beyond the view and control not only of potential enemies but also of citizens of democracies themselves. Far more than a simple technology, Chamayou shows, drones are profoundly influencing what it means for a democracy to wage war. A Theory of the Drone will be essential reading for all who care about this important question.
