A Los Alamos Concept for Accelerator Transmutation of Waste and Energy Production (ATW); December 10 - 12, 1990 External Review
Los Alamos, NM: Los Alamos National Laboratory, 1990. One of a relatively few copies made for the Review. Comb Binding. A RARE surviving copy! Illustrated cover. Vugraphs with text and illustrations. Unpaginated [about 1 inch of material, most sheets printed on each side.] Name in ink on front cover [Kinkead, one of the presenters!]. Ink notations made by a participant. Some transfer between pages but information on pages clearly legible. The first item present is the agenda. This is followed by Overview of the Concept presented and an Overview of a Near-Term Application of ATW High-Level Defense Wastes Hanford, both by Edward Arthur. The next presentation was LINAC Technology, Accelerator Technology for the ATW System by George Lawrence. The next day started with a presentation on Intense Thermal Neutron Source ATW Neutron Production by Paul Lisowski and this was followed by a presentation on ATW Target/Blanket Design: Application to Hanford Defense Waste by Michael Cappiello which in turn was followed by a Chemistry and Materials presentation on Aqueous Chemical Processing for the Tc and Tc/Np Transmutation Blankets by Stephen Yarbro and ATW Materials Issues by Karl Staudhammer. Next was an Overview of Advanced Application by Edward Arthur followed by Advanced Technology: Fission Energy Without a High Level Waste Stream by Charles Bowman and Advanced Chemistry: Molten Salt Chemistry for the Advanced ATW Concept by Scott Kinkead. The concluding presentation was Summary and Research Issues by Edward Arthur. "Accelerator transmutation of waste" (ATW) and is being investigated as an alternative to the geologic storage solution. The basic concept of ATW is simply to "finish the job" of burning or transmuting the radioactive waste through intense neutron flux, thereby drastically reducing its radioactivity. Again, bombardment with large numbers of neutrons is considered as a way to either fission the heavier elements into less dangerous species or convert the lighter ones through absorption. A particle accelerator can be used as a source of high-energy protons, which can then be used to create neutrons through a process known as "spallation." This occurs when a proton collides with a heavy nucleus in the spallation target, after which the nucleus ejects a large number of neutrons proportional to the energy of the original proton. However, advances both in the technology needed to accelerate the protons and the understanding of spallation physics have prompted investigation of accelerator-created neutrons for waste treatment. While doing so may create further radioactive elements both in the spallation target and in the bulk of the waste, by eliminating the long-lived ones ATW can theoretically change the nature and the timescale of the problem considerably. Condition: Good.
