Available in PDF, EPUB and Kindle. Book excerpt: DOE Tank Waste: How clean is clean enough? The U.S. Congress asked the National Academies to evaluate the Department of Energy's (DOE's) plans for cleaning up defense-related radioactive wastes stored in underground tanks at three sites: the Hanford Site in Washington State, the Savannah River Site in South Carolina, and the Idaho National Laboratory. DOE plans to remove the waste from the tanks, separate out high-level radioactive waste to be shipped to an off-site geological repository, and dispose of the remaining lower-activity waste onsite. The report concludes that DOE's overall plan is workable, but some important challenges must be overcomeâ€"including the removal of residual waste from some tanks, especially at Hanford and Savannah River. The report recommends that DOE pursue a more risk-informed, consistent, participatory, and transparent for making decisions about how much waste to retrieve from tanks and how much to dispose of onsite. The report offers several other detailed recommendations to improve the technical soundness of DOE's tank cleanup plans.

Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from Congress, the U.S. Department of Energy (DOE) asked the National Academies to evaluate its plans for managing radioactive wastes from spent nuclear fuel at sites in Idaho, South Carolina, and Washington. This interim report evaluates storage facilities at the Savannah River Site in South Carolina, with a particular focus on plans to seal the tanks with grouting. The report finds that tanks at the site do not necessarily need to be sealed shut as soon as the bulk of the waste has been removed. Postponing permanent closure buys more time for the development and application of emerging technologies to remove and better immobilize residual waste, without increasing risks to the environment or delaying final closure of the "tank farms." The report also recommends alternatives to address the lack of tank space at the site, as well as the need for focused R&D activities to reduce the amount and improve the immobilization of residual waste in the tanks and to test some of the assumptions used in evaulating long-term risks at the site.

Book Synopsis Nuclear Waste by : Gene Aloise

Download or read book Nuclear Waste written by Gene Aloise. This book was released on 2009-02. Available in PDF, EPUB and Kindle. Book excerpt: The Dept. of Energy (DoE) manages more than 56 million gallons of radioactive and hazardous waste stored in 177 underground tanks at its Hanford Site in Wash. State. Many of these aging tanks have already leaked waste into the soil. Meanwhile, DoE¿s planned process for emptying the tanks and treating the waste has experienced delays, lengthening the time the tanks will store waste and intensifying concerns about the tanks¿ viability during a long cleanup process. This report addresses: (1) the condition, contents, and long-term viability of Hanford¿s underground tanks; (2) DoE¿s strategy for managing the tanks; and (3) the extent to which DoE has weighed the risks and benefits of its tank mgmt. strategy against the growing costs of that strategy.

Book Synopsis Waste Forms Technology and Performance by : National Research Council

Download or read book Waste Forms Technology and Performance written by National Research Council. This book was released on 2011-09-05. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy's Office of Environmental Management (DOE-EM) is responsible for cleaning up radioactive waste and environmental contamination resulting from five decades of nuclear weapons production and testing. A major focus of this program involves the retrieval, processing, and immobilization of waste into stable, solid waste forms for disposal. Waste Forms Technology and Performance, a report requested by DOE-EM, examines requirements for waste form technology and performance in the cleanup program. The report provides information to DOE-EM to support improvements in methods for processing waste and selecting and fabricating waste forms. Waste Forms Technology and Performance places particular emphasis on processing technologies for high-level radioactive waste, DOE's most expensive and arguably most difficult cleanup challenge. The report's key messages are presented in ten findings and one recommendation.
