Nuclear energy is contributing to the long-term solution to stave off climate change. However, current nuclear fission technology accesses only about 1-3% of the nuclear energy content of natural uranium, which is inefficient, and also creates a radioactive waste disposal problem. Combining nuclear fission technology with emerging nuclear fusion technology to create a fusion-fission hybrid would yield extra fusion neutrons to 1) convert much more of the uranium into fissionable material, which would increase efficient utilization of the nuclear fuel resource, and 2) significantly reduce (by fission) the most long-lived radioactive nuclear waste. This book describes fusion-fission hybrid physics and technology. The first parts briefly review nuclear fission principles and describe design and safety of nuclear fission reactors; then the fundamentals of nuclear fusion and fusion reactor concepts are described, together with ongoing and future challenges and anticipated developments in this not-yet matured technology. Chapters cover the scientific basis of nuclear fission and the fission fuel cycle, advanced fission reactors, safety aspects, the scientific and technological basis of nuclear fusion power, future improvements expected, and then the fusion-fission hybrid (FFH) breeder and burner reactor concept principles, with illustrative FFH design concepts, safety analyses, and examples of the use of fusion neutrons for helping to achieve burning and breeding fission fuel cycles. This concise work is essential reading for researchers and policy makers in nuclear energy research and engineering, including advanced students.

" With brief, humorous stories the author paints a vivid picture of his development from a Southern boy more concerned with fishing and football into an applied nuclear physicist. His stories from youth, insider's view of academia and firsthand account of a life in physics should interest a wide audience." -- Kirkus Reviews This book is both a scientific memoir of a prominent applied physicist and a chronicle of the history of his family from the earliest days of America. The first part of this expansive memoir traces the Stacy family from the original settling of Georgia in the Midway Church community in the 18th century, their migration to southwest Georgia to escape the devastation left behind by Sherman's army in the 19th century, through the author's unusual experiences as a youth in the vanished world of the small-town South of the mid-20th century. His serendipitous path from southwest Georgia through Georgia Tech and the Marine Corps to the world of applied nuclear science is amusingly described. The second part of the book is a broad scientific memoir covering the author's advanced education at Georgia Tech and MIT as an applied nuclear physicist and his 50 years of internationally recognized research, design and teaching about nuclear reactors and nuclear fusion. This memoir provides unique insights into the history of physics and into the world of applied nuclear physics laboratories and of a major research university, as well as an interesting account of the author's personal life, family, friendships, travels and reading.
