Lapa Chapter 21 Risk Assessment in Accident Prevention Considering Uncertainty and Human Factor Influence 407 Katarína Zánická Hollá Preface Due to economic growth and increasing population, energy demands must be satisfied in a sustainable manner assuring inherent safety, efficiency and minimized environmental impact. Nuclear power has long posed a dilemma for environmentalists and scientists alike. On the one hand it is seen as a cheap, clean energy source whilst on the other some have concerns over its ability to dispose of radioactive waste. Whichever viewpoint one may assume, nuclear power is at the forefront of clean energy technology and can be made available on a large scale to meet energy needs of the rapidly growing world. Today’s nuclear reactors are safe and highly efficient energy systems that give electricity and a multitude of co-generation energy products ranging from potable water to heat for industrial applications. Meanwhile, a catastrophic earthquake and a tsunami in Japan led to the nuclear accident that forced us to rethink our approach to nuclear safety and design requirements. It also encouraged the growing of interest for advanced nuclear energy systems and next generation nuclear reactors, inherently capable of withstanding natural disasters, avoiding catastrophic consequences and leaving no environmental impact. Advances in reactor designs, materials and human- machine interfaces assure safety and reliability of emerging reactor technologies, eliminating possibilities for high-consequence human error, such as those which have occurred in the past. New instrumentation and control technologies based in digital systems, novel sensors and measurement approaches facilitate safety, reliability and economic competitiveness of nuclear power options. Autonomous operation scenarios are becoming increasingly popular to consider for small modular systems designed for remote regions with limited industrial infrastructure or regions with no such infrastructure but with human population whose safety, prosperity and growth depend on a reliable energy supply. This book is one in a series of books on nuclear power published by InTech. It consists of four major sections and contains twenty-one chapters on topics from key subject areas pertinent to instrumentation and control, operation reliability, system aging and human-machine interfaces.The book opens with the section on instrumentation and control aspects of nuclear power. The following sections and included chapters address selected issues in reliability and failure mechanisms, component aging, plant X Preface operation and human factors. The book shows both advantages and challenges emphasizing the need for further development and innovation. With all diversity of topics in 21 chapters, the issues of nuclear power control, reliability and human factor represent a common thread that is easily identifiable in all chapters of the book. The “systems 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 works together. The goal of this book and the entire book series on nuclear power is to present nuclear power to our readers as a promising energy source that has a unique potential to meet energy demands with minimized environmental impact, near-zero carbon footprint, and competitive economics via robust potential applications. The book targets a broad potential readership group - students, researchers and specialists in the field - who are interested in learning about nuclear power. The idea is to facilitate intellectual cross-fertilization between field experts and non-field experts taking advantage of methods and tools developed by both groups. The book will hopefully inspire future research and development efforts, innovation by stimulating ideas. We hope our readers will enjoy the book and will find it both interesting and useful.
