This book was released on 2017-09-15 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy (DOE) is demonstrating a technology called bulk vitrification, in parallel with the Hanford waste treatment plant, to treat a portion of the radioactive waste stored in 177 tanks at its Hanford site in southeastern Washington state. DOE faces technical and management problems that have affected the original objectives to justify demonstrating the bulk vitrification technology. This report discusses the extent to which DOE (1) has managed the bulk vitrification demonstration project consistent with DOE management guidance and (2) continues to need a supplemental technology, such as bulk vitrification, to treat a portion of the low-activity tank waste. To assess DOE's management of the project, GAO reviewed reports by DOE and others and discussed the project with DOE and contractor officials.

Book excerpt: The Dept. of Energy¿s Office of Environ. Mgmt. (EM) is responsible for one of the world¿s largest cleanup programs: treatment and disposal of radioactive and hazardous waste created as a by-product of nuclear weapons production and energy research at sites across the country, such as EM¿s Hanford Site in Wash. State and the Savannah River Site in S. Carolina. Computer models (CM) -- which represent physical and bio-geochemical processes as math formulas -- are one tool EM uses in the cleanups. This report: (1) describes how EM uses CM in cleanup decisions; (2) evaluates how EM ensures the quality of its CM; and (3) assesses EM¿s overall strategy for managing its CM. This is a print on demand report.

This book was released on 2020-04-30 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy's Office of Environmental Management is responsible for managing and cleaning up the waste and contamination at the Hanford Nuclear Reservation, the nation's biggest and most complex nuclear cleanup challenge. At the site, 177 underground tanks collectively contain about 211 million liters of waste that includes high-activity and low-activity materials. At the request of Congress, Final Review of the Study on Supplemental Treatment Approaches of Low-Activity Waste at the Hanford Nuclear Reservation: Review #4 focuses on approaches for treatment and disposal of the supplemental portion of the low-activity waste from the tanks. This review report discusses developments since the publication of Review #3 and provides a summary of public comments on the third committee review report. The authoring committee then shares their views on these comments and whether they change any of the findings or recommendations in the third review report.
Download or read book High Risk Series written by Gene L. Dodaro and published by DIANE Publishing. This book was released on 2009-12 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fed. gov¿t. is the world's largest and most complex entity, with about $3 trillion in outlays in FY 2008. Reports on high-risk areas bring focus to areas needing attention due to their greater vulnerabilities to fraud, waste, abuse, and mismanagement. These reports also identify areas needing transformation to address major economy, efficiency, or effectiveness challenges. This 2009 update presents the status of high-risk areas listed in 2007 and identifies new high-risk areas. Solutions to high-risk problems offer the potential to save billions of dollars, dramatically improve service to the public, strengthen confidence and trust in the performance and accountability of the U.S. gov¿t., and ensure the ability of gov¿t. to deliver on its promises.

This book was released on 2006-10-12 with total page 214 pages. 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.

Download or read book Strategy and Methodology for Radioactive Waste Characterization written by International Atomic Energy Agency and published by IAEA. This book was released on 2007 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade significant progress has been achieved in the development of waste characterization and control procedures and equipment as a direct response to ever-increasing requirements for quality and reliability of information on waste characteristics. Failure in control procedures at any step can have important, adverse consequences and may result in producing waste packages which are not compliant with the waste acceptance criteria for disposal, thereby adversely impacting the repository. The information and guidance included in this publication corresponds to recent achievements and reflects the optimum approaches, thereby reducing the potential for error and enhancing the quality of the end product. -- Publisher's description.
Download or read book Nuclear Wastes written by National Research Council and published by National Academies Press. This book was released on 1996-02-23 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
