Book excerpt: Further validation of the Hanford Waste Vitrification Plant (HWVP) feed simulants will be performed by analyzing offgases during crucible melting of actual waste glasses and simulants. The existing method of vitrifying radioactive laboratory-scale samples will be modified to allow offgas analysis during preparation of glass for product testing. The analysis equipment will include two gas chromatographs (GC) with thermal conductivity detectors (TCD) and one NO/NO[sub x] analyzer. This equipment is part of the radioactive formating offgas system. The system will provide real-time analysis of H[sub 2], O[sub 2], N[sub 2], NO, N[sub 2]O, NO[sub 2], CO, CO[sub 2], H[sub 2]O, and SO[sub 2]. As with the prior melting method, the product glass will be compatible with durability testing, i.e., Product Consistency Test (PCT) and Material Characterization Center (MCC-1), and crystallinity analysis. Procedures have been included to ensure glass homogeneity and quenching. The radioactive glass will be adaptable to Fe[sup +2]/[Sigma]Fe measurement procedures because the atmosphere above the melt can be controlled. The 325 A-hot cell facility is being established as the permanent location for radioactive offgas analysis during formating, and can be easily adapted to crucible melt tests. The total costs necessary to set up and perform offgas measurements on the first radioactive core sample is estimated at $115K. Costs for repeating the test on each additional core sample are estimated to be $60K. The schedule allows for performing the test on the next available core sample.

Book Synopsis Evaporation of a Large Decontaminated Hanford Tank Sample by :
Download or read book Evaporation of a Large Decontaminated Hanford Tank Sample written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A radioactive sample (approximately 15 L) from Hanford tank 241-AN-102 was concentrated via evaporation at reduced pressure and temperature, to support flowsheet development and regulatory approval for the Hanford River Protection Project Waste Treatment Plant (RPP-WTP). The received sample (Envelope C) had been pretreated at the Savannah River Technology Center (SRTC) for removal of strontium and transuranic ions by precipitation and removal of cesium and technetium via ion exchange. The resulting pretreated Low Activity Waste (LAW) stream was the feed material for this evaporation test. The goals of this evaporation were to: (1) provide operating data -- including foaming and scaling tendencies -- for scale-up purposes, (2) obtain liquid and off-gas samples during steady-state operation for regulatory analysis, (3) conduct a ''final boildown'' after the steady-state operation to determine the solubility endpoint of the solution and the major precipitants, and (4) provide concentrated feed for a melter vitrification study to produce several kilograms of immobilized LAW glass product.

Book Synopsis Strategy and Methodology for Radioactive Waste Characterization by : International Atomic Energy Agency
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.

Book Synopsis Nuclear Waste Cleanup Technologies and Opportunities by : Robert Noyes
Download or read book Nuclear Waste Cleanup Technologies and Opportunities written by Robert Noyes and published by Elsevier. This book was released on 1995-12-31 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the largest, most complicated and expensive environmental problems in the United States is the cleanup of nuclear wastes. The US Department of Energy (DOE) has approximately 4,000 contaminated sites covering tens of thousands of acres and replete with contaminated hazardous or radioactive waste, soil, or structures. In addition to high-level waste, it has more than 250,000 cubic meters of transuranic waste and millions of cubic meters of low-level radio-active waste. In addition, DOE is responsible for thousands of facilities awaiting decontamination, decommissioning, and dismantling. DOE and its predecessors have been involved in the management of radioactive wastes since 1943, when such wastes were first generated in significant quantities as by-products of nuclear weapons production. Waste connected with DOE's nuclear weapons complex has been accumulating as a result of various operations spanning over five decades. The cost estimates for nuclear waste cleanup in the United States have been rapidly rising. It has recently been estimated to be in a range from $200 to $350 billion. Costs could vary considerably based on future philosophies as to whether to isolate certain sites (the ""iron fence"" philosophy), or clean them up to a pristine condition (the ""greenfields"" philosophy). Funding will also be based on Congressional action that may reduce environmental cleanup, based on budget considerations.
Book Synopsis Tank Waste Retrieval, Processing, and On-site Disposal at Three Department of Energy Sites by : National Research Council
Download or read book Tank Waste Retrieval, Processing, and On-site Disposal at Three Department of Energy Sites written by National Research Council and published by National Academies Press. This book was released on 2006-09-12 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.
