The world is rapidly growing; country economies developing at accelerated growth rates, technology advances improve quality of life and become available to larger and larger populations. At the same time we are coming to a realization that we are responsible for our planet. We have to make sure that our continuous quest for prosperity does not backfire via catastrophic irreversible climate changes, and depleted or limited resources that may challenge the very existence of future generations. We are at the point in our history when we have to make sure that our growth is sustainable. Energy demands due to economic growth and increasing population must be satisfied in a sustainable manner assuring inherent safety, efficiency and no or minimized environmental impact. New energy sources and systems must be inherently safe and environmentally benign. These considerations are among the reasons that lead to serious interest in deploying nuclear power as a sustainable energy source. Today’s nuclear reactors are safe and highly efficient energy systems that offer electricity and a multitude of co-generation energy products ranging from potable water to heat for industrial applications. At the same time, catastrophic earthquake and tsunami events in Japan resulted in the nuclear accident that forced us to rethink our approach to nuclear safety, design requirements and facilitated growing interests in advanced nuclear energy systems, next generation nuclear reactors, which are inherently capable to withstand natural disasters and avoid catastrophic consequences without any environmental impact. This book is one in a series of books on nuclear power published by InTech. It consists of six major sections housing twenty chapters on topics from the key subject areas pertinent to successful development, deployment and operation of nuclear power systems worldwide: Nuclear Power Deployment 1. Nuclear Naval Propulsion 2. Deployment Scenarios for New Technologies 3. The Investment Evaluation of Third-Generation Nuclear Power - from the Perspective of Real Options 4.

Hydrogen Output from Catalyzed Radiolysis of Water. Our book opens with the section on general aspects of nuclear power deployment. Later sections address selected issues in operation and decommissioning, economics and environmental effects. The book shows both advantages and challenges emphasizing the need for further development and innovation. Advances in nuclear waste management and thorium-based fuel cycles lead to environmentally benign nuclear energy scenarios and ultimately, towards nuclear energy sustainability. Improvements in applications and efficiency of energy conversion facilitate economics competitiveness of nuclear power. With all diversity of topics in 20 chapters, the nuclear power deployment, operation and sustainability is the common thread that is easily identifiable in all chapters of our book. The “system-thinking” approach allows synthesizing the entire body of provided information into a consistent integrated picture of the real-life complex engineering system – nuclear power system – where everything is working together.
