Target/blanket Conceptual Design for the Los Alamos ATW Concept


Book Description

The Los Alamos Accelerator Transmutation of Waste (ATW) concept has many potential applications that include defense waste transmutation, defense material production (i.e., tritium and 238Pu), and the transmutation of hazardous nuclear wastes from commercial nuclear reactors (fission products and actinides). A more advanced long-term Los Alamos effort is investigating the potential of an accelerator- driven system to produce fission energy with a minimal nuclear waste stream. All applications employ a high-energy (800- to 1600-MeV), high-current (25--250 mA) proton linear accelerator as the driver. In this report, we discuss only the target/blanket conceptual design for the commercial nuclear waste application. A conceptual design for the target/blanket of the Los Alamos ATW concept has been presented. The neutronics, mechanical design, and heat transfer have been investigated in some detail for the base-case design. Much more work needs to be done, but at this point it appears that the design is feasible and will approach the design goal of supporting two commercial power reactors with each target/blanket module.










Nuclear Wastes


Book Description

Disposal of radioactive waste from nuclear weapons production and power generation has caused public outcry and political consternation. Nuclear Wastes presents a critical review of some waste management and disposal alternatives to the current national policy of direct disposal of light water reactor spent fuel. The book offers clearcut conclusions for what the nation should do today and what solutions should be explored for tomorrow. The committee examines the currently used "once-through" fuel cycle versus different alternatives of separations and transmutation technology systems, by which hazardous radionuclides are converted to nuclides that are either stable or radioactive with short half-lives. The volume provides detailed findings and conclusions about the status and feasibility of plutonium extraction and more advanced separations technologies, as well as three principal transmutation concepts for commercial reactor spent fuel. The book discusses nuclear proliferation; the U.S. nuclear regulatory structure; issues of health, safety and transportation; the proposed sale of electrical energy as a means of paying for the transmutation system; and other key issues.




Planetary Emergencies: 10th International Seminar On Nuclear War


Book Description

This series started in 1981 with the Erice Seminars when the danger of a nuclear East-West confrontation was menacing the world. The volumes reproduce the crucial steps, from the Nuclear Winter to the Strategic Defense Initiative. After the collapse of the U.S.S.R., new emergencies are now to be faced such as the danger of proliferation of Weapons for Mass Destruction (WMD), the North-South confrontation on ecological problems and the new deal for Science and Technology to help developing countries in their struggle for a better standard of life. The Erice Seminars have attracted the attention of world leaders in Science, Technology and Culture.




Nuclear Methods For Transmutation Of Nuclear Waste: Problems, Perspectives, Cooperative Research - Proceedings Of The International Workshop


Book Description

Long-lived radioactive materials from the operation of nuclear power plants and from the maintenance and decommissioning of nuclear weapons pose environmental and security risks. Technologies that would counter such risks are under intense study worldwide. One such technology, transmutation by nuclear means into shorter-lived materials, was the subject of an international workshop in Russia, where the need for a viable solution of this problem is particularly strong.Current problems of that technology and future perspectives and cooperative research possibilities involving Russian and East European facilities are discussed by scientists from Russia, the United States and seven other countries representing basic research institutes, former nuclear weapons laboratories and nuclear industries. Computer modeling, data bases and experimental investigations needed for the conceptualization of demonstration, prototype and production facilities are treated in detail. Progress on the planning and construction of the first demonstration facilities is also described.From these proceedings it becomes evident that the problems inherent in radioactive waste accumulation can be solved only by international cooperation in which conventional methods are supplemented by new technologies, and that such a solution may require a sustained effort comparable to the Manhattan Project and the analogous project in the former USSR at the beginning of the nuclear era.

Bmdo Technology And The Electric Utility Industry


Book Description

Since the early 1980's , the U.S. has encouraged industry to partner with Fed. agencies to transfer and commercialize federally funded R&D. This report, written in support of the Ballistic Missile Defense Organization's (BMDO's) Tech. Applications program, is intended to put the electric utility industry in touch with developers of a wide range of highly advanced technology funded by BMDO that could assist those utilities in meeting a more competitive environment. Includes: transmission and distribution systems, fossil fuel power generation, environmental compliance, and load mgmt. Contacts provided.
