Fusion-Fission Hybrid Nuclear Reactors

Fusion-Fission Hybrid Nuclear Reactors

For enhanced nuclear fuel utilization and radioactive waste reduction  

by Weston M. Stacey

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 with emerging nuclear fusion technology to create a fusion-fission hybrid would yield extra neutrons to convert much more of the uranium into fissionable material, which would increase efficiency and reduce the radioactive waste. While nuclear energy is presently contributing to the solution of the global climate change problem, it has the potential to make a much larger contribution by combining relatively neutron-sparse nuclear fission reactors with copious nuclear fusion neutron sources in order to more efficiently utilize uranium (and later thorium) nuclear fission energy fuel resources and to destroy long-lived high level radioactive waste, in “fusion-fission hybrid” reactors.

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.
