Hardcover. Condizione: Very good. Presumed first edition/first printing. xiii, [1], 362 p. Illustrations. References. Index. This is one of the NATO ASI Series, 1. Disarmament Technologies, Vol. 15. This volume presents the proceedings of the NATO Advanced Research Workshop on Advanced Nuclear Systems Consuming Excess Plutonium, Moscow, Russia, 13-16 October 1996. This is a survey of current developments in the field of plutonium disposal by the application of advanced nuclear systems, both critical and subcritical. National research and development plans are also 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 volume draws the conclusion that the various systems proposed are technically feasible, even though not yet technically mature. The book presents a 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.…

Hardcover. Condizione: Very good. Presumed first edition/first printing. xv, [1], 339, [1] p. Illustrations. Bibliography. Index. This is part of the NATO ASI Series, 1. Disarmament Technologies, Vol. 4. This was published in cooperation with the NATO Scientific Affairs Division. This volume presents the Proceedings of the NATO Advanced Research Workshop on Disposal of Weapons Plutonium--Approaches and Prospects, St. Petersburg, Russia, May 14-17, 1995. In the immediate term, plutonium recovered from dismantled nuclear warheads will have to be stored securely, under international safeguards where possible. One of the principal alternatives for the disposition of this plutonium is to blend it with high-level waste as it is vitrified for final disposal in a geologic repository. The high radioactivity of the resulting product provides self-shielding and ensures that the Pu cannot be separated without the development of highly sophisticated technology. This third NATO ARW on the disposal of weapons-grade plutonium discusses the non-reactor disposition option, presenting a thorough evaluation of the pros and cons. In broad terms, the workshop presents an exchange of information on waste vitrification, including technical feasibility as well as the necessary stringent safeguards. It discusses the different approaches to the optimum techniques and credible alternatives for immobilizing transuranics and fission products for disposal. It introduces new disposal techniques, in particular matrix immobilization followed by deep borehole disposal. It assesses the implications of safeguarding requirements. And it identifies common areas in which defined research tasks can be initiated in cooperative partnership. Carl E. Walter was associated with the Lawrence Livermore National Laboratory.…
