This report examines the recycling of plutonium as thermal mixed-oxide (MOX) fuel in pressurised water reactors (PWRs) in order to discover the number of times plutonium can effectively be recycled. In particular, it describes an exercise based on a realistic, multiple-recycle scenario, which followed plutonium through five generations of recycling in a PWR. It considers both a standard PWR design currently in use and a highly moderated design, in order to provide a better understanding of their relative merits, as well as giving an insight into the limitations of multiple recycling and the long-term toxicity of fission products and actinides.

One of the greatest challenges for nuclear energy is how to properly manage the highly radioactive waste generated during irradiation in nuclear reactors. Accelerator Driven Systems (ADSs) may offer new prospects and advantages for the transmutation of such high level nuclear waste. ADS or accelerator driven transmutation of waste (ATW) consists of a high power proton accelerator, a heavy metal spallation target that produces neutrons when bombarded by the high power beam, and a sub-critical core that is neutronically coupled to the spallation target. This publication provides a comprehensive state of the art of the ADS technology by representing the different ADS concepts proposed worldwide in the last 15 years, as well as the related R&D activities and demonstration initiatives carried out at national international level.

A survey of recent developments in the field of plutonium disposal by the application of advanced nuclear systems, both critical and subcritical. Current national R&D plans are summarized. The actinide-fuelled critical reactors are associated with control problems, since they tend to have a small delayed neutron fraction coupled with a small Doppler effect and a positive void coefficient. Current thinking is turning to accelerator-driven subcritical systems for the transmutation of actinides. The book's conclusion is that the various systems proposed are technically feasible, even though not yet technically mature. The book presents a unique summary and evaluation of all relevant possibilities for burning surplus plutonium, presented by experts from a variety of different disciplines and interests, including the defence establishment. The obvious issue - the non-proliferation of nuclear weapons - is vital, but the matter represents a complex technological challenge that also requires an assessment in economic terms.

Advanced Reactors: Physics, Design and Economics contains the proceedings of the International Conference held at Atlanta, Georgia on September 8-11, 1974. Organized according to the sessions of the conference, this book first describes the national programs for the development of advanced reactors. Subsequent sessions centers on economics of advanced reactors; developments in reactor theory; advanced reactor experiments and analysis; cross section data and calculational methods. The last three sessions focus on sensitivity analysis of integral reactor parameters; problems in the design of advanced reactors; and the design and operational experience for advanced reactors.
