Plutonium

This NATO Advanced Research Workshop on Disposal of Weapons Plutonium is a follow-up event to two preceding workshops, each dealing with a special subject within the overall disarmament issue: "Disposition of Weapon Plutonium", sponsored by the NATO Science Committee. The first workshop of this series was held at the Royal Institute of International Affairs in London on 24-25 January 1994, entitled "Managing the Plutonium Surplus, Applications, and Options". Its over all goal was to clarify the current situation with respect to pluto nium characteristics and availability, the technical options for use or disposal, and their main technical, environmental, and economic constraints. In the immediate term, plutonium recovered from dismantled nuclear warheads will have to be stored securely, and under international safeguards if possible. In the intermediate term, the principal alter natives for disposition of this plutonium are: irradiation in mixed oxide (MOX) fuel assemblies in existing commercial light-water reac tors or in specially adapted light-water reactors capable of operation with full cores of MOX fuel .and irradiation in future fast reactors. Another option is to blend plutonium with high-level waste as it is vitrified for final disposal in a geologic repository. In both cases, the high radioactivity of the resulting products provides "self shielding" and prevents separation of plutonium without already developed and available sophisticated technology. The so-called "spent fuel standard" as an effective protection barrier is - quired in either case.

This book explains the characteristics of plutonium, where it is found, how it is used by humans, and its relationship to other elements found in the periodic table.

The first atomic bombs were constructed at the Los Alamos National Laboratory, where lab workers disposed of waste plutonium in nearby canyons leading to the Rio Grande. Today, the environmental consequences are just beginning to be understood as scientists examine the effects created by past mishandling of one of the most toxic chemical wastes known. Written in an engaging, accessible style, Plutonium and the Rio Grande is the first book to offer a complete exploration of this environmental history. It includes an explanation of what plutonium is, how much of it was released by the Los Alamos workers, and how much entered the river system directly from waste disposal and indirectly, as a result of atomic bomb fallout. The book includes extensive appendices, maps, diagrams, and photographs. Environmental managers, ecologists, hydrologists and other river specialists, as well as concerned general readers will find the book readable and informative.

The Toxicity of Plutonium, Americium and Curium provides a biological basis for an assessment of the radiological health problems resulting from human exposure to americium, curium, and plutonium. This book discusses the method of injection of the chelating agent DTPA for removing soluble forms of americium, curium, and plutonium. Organized into 10 chapters, this book begins with an overview of the biological effects in man that are attributed to exposure to actinides. This text then examines the uses of americium and curium in transmission scanning studies in tissues, in smoke detectors, and in neutron sources. Other chapters consider the metabolism or effects of plutonium in humans that can be employed to predict the potential consequences of human exposure. This book discusses as well routes of entry of radioactive materials into the body by inhalation, by ingestion, through cuts, or by absorption through the intact skin. The final chapter deals with the assessment of the radiological health problems resulting from the use of mixed oxide fuels of uranium and plutonium in light water reactors. This book is a valuable resource for scientists.
