Book Identification of Potential Transuranic Waste Tanks at the Hanford Site

Download or read book Identification of Potential Transuranic Waste Tanks at the Hanford Site written by and published by . This book was released on 1995 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this document is to identify potential transuranic (TRU) material among the Hanford Site tank wastes for possible disposal at the Waste Isolation Pilot Plant (WIPP) as an alternative to disposal in the high-level waste (HLW) repository. Identification of such material is the initial task in a trade study suggested in WHC-EP-0786, Tank Waste Remediation System Decisions and Risk Assessment (Johnson 1994). The scope of this document is limited to the identification of those tanks that might be segregated from the HLW for disposal as TRU, and the bases for that selection. It is assumed that the tank waste will be washed to remove soluble inert material for disposal as low-level waste (LLW), and the washed residual solids will be vitrified for disposal. The actual recommendation of a disposal strategy for these materials will require a detailed cost/benefit analysis and is beyond the scope of this document.

Book Hanford Site Secondary Waste Roadmap

Download or read book Hanford Site Secondary Waste Roadmap written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy (DOE) is making plans to dispose of 54 million gallons of radioactive tank wastes at the Hanford Site near Richland, Washington. The high-level wastes and low-activity wastes will be vitrified and placed in permanent disposal sites. Processing of the tank wastes will generate secondary wastes, including routine solid wastes and liquid process effluents, and these need to be processed and disposed of also. The Department of Energy Office of Waste Processing sponsored a meeting to develop a roadmap to outline the steps necessary to design the secondary waste forms. Representatives from DOE, the U.S. Environmental Protection Agency, the Washington State Department of Ecology, the Oregon Department of Energy, Nuclear Regulatory Commission, technical experts from the DOE national laboratories, academia, and private consultants convened in Richland, Washington, during the week of July 21-23, 2008, to participate in a workshop to identify the risks and uncertainties associated with the treatment and disposal of the secondary wastes and to develop a roadmap for addressing those risks and uncertainties. This report describes the results of the roadmap meeting in Richland. Processing of the tank wastes will generate secondary wastes, including routine solid wastes and liquid process effluents. The secondary waste roadmap workshop focused on the waste streams that contained the largest fractions of the 129I and 99Tc that the Integrated Disposal Facility risk assessment analyses were showing to have the largest contribution to the estimated IDF disposal impacts to groundwater. Thus, the roadmapping effort was to focus on the scrubber/off-gas treatment liquids with 99Tc to be sent to the Effluent Treatment Facility for treatment and solidification and the silver mordenite and carbon beds with the captured 129I to be packaged and sent to the IDF. At the highest level, the secondary waste roadmap includes elements addressing regulatory and performance requirements, waste composition, preliminary waste form screening, waste form development, process design and support, and validation. The regulatory and performance requirements activity will provide the secondary waste-form performance requirements. The waste-composition activity will provide workable ranges of secondary waste compositions and formulations for simulants and surrogates. Preliminary waste form screening will identify candidate waste forms for immobilizing the secondary wastes. The waste form development activity will mature the waste forms, leading to a selected waste form(s) with a defensible understanding of the long-term release rate and input into the critical decision process for a secondary waste treatment process/facility. The process and design support activity will provide a reliable process flowsheet and input to support a robust facility design. The validation effort will confirm that the selected waste form meets regulatory requirements. The final outcome of the implementation of the secondary waste roadmap is the compliant, effective, timely, and cost-effective disposal of the secondary wastes. The work necessary to address the programmatic, regulatory, and technical risks and uncertainties identified through the Secondary Waste Roadmap Workshop are assembled into several program needs elements. Programmatic/Regulatory needs include: Select and deploy Hanford tank waste supplemental treatment technology Provide treatment capability for secondary waste streams from tank waste treatment Develop consensus on secondary waste form acceptance. Technology needs include: Define secondary waste composition ranges and uncertainties Identify and develop waste forms for secondary waste immobilization and disposal Develop test methods to characterize secondary waste form performance. Details for each of these program elements are provided.

Book Existing Data on the 216 Z Liquid Waste Sites

Download or read book Existing Data on the 216 Z Liquid Waste Sites written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During 36 years of operation at the Hanford Site, the ground has been used for disposal of liquid and solid transuranic and/or low-level wastes. Liquid waste was disposed in surface and subsurface cribs, trenches, French drains, reverse wells, ditches and ponds. Disposal structures associated with Z Plant received liquid waste from plutonium finishing and reclamation, waste treatment and laboratory operations. The nineteen 216-Z sites have received 83% of the plutonium discharged to 325 liquid waste facilities at the Hanford Site. The purpose of this document is to support the Hanford Defense Waste Environmental Impact Statement by drawing the existing data together for the 216-Z liquid waste disposal sites. This document provides an interim reference while a sitewide Waste Information Data System (WIDS) is developed and put on line. Eventually these and additional site data for all Hanford waste disposal sites will be available on WIDS. Compilation of existing data is the first step in evaluating the need and developing the technology for long-term management of these waste sites. The scope of this document is confined to data describing the status of the 216-Z waste sites as of December 31, 1979. Information and sketches are taken from existing documents and drawings.

Book Hanford Site Mixed Waste Disposal

Download or read book Hanford Site Mixed Waste Disposal written by and published by . This book was released on 2001 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant volumes of mixed low-level waste (MLLW) will be generated as part of the management and remediation of the Hanford Site. The MLLW that is generated as part of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) process will largely be managed as part of that remediation effort, with disposal likely in the centralized Environmental Restoration Disposal Facility (ERDF). Other unique MLLW streams will be produced as part of the Hanford program to disposition tank wastes, and will include failed equipment (melters) and immobilized low-activity wastes. These disposal operations are in the early planning stages and will likely require development of specialized disposal facilities. This paper will focus on disposal of the more ''routine'' waste streams, those currently stored onsite in permitted Resource Conservation and Recover Act (RCRA) facilities, or those newly-generated MLLW streams requiring management in permitted RCRA facilities. These waste streams typically include RCRA regulated MLLW debris, sludges, soils and solidified liquids. In September 1999, the United States Department of Energy, Richland Operations Office and Fluor Hanford began disposing of Land Disposal Restrictions (LDR) compliant MLLW in a RCRA mixed waste disposal facility at the Hanford Site. This facility, one of two at Hanford, is an integral part of a comprehensive program to treat and dispose of the Hanford inventory of stored MLLW, and may aid the DOE Complex in disposing of its legacy of MLLW. The Final Waste Management Programmatic Environmental Impact Statement (WM PEIS) record-of-decision (ROD) for MLLW identifies Hanford as one of the disposal sites for much of the DOE complex MLLW. A few actions remain to be completed before waste from offsite generators can be shipped to the Hanford Mixed Waste Facilities for disposal. These actions include, but are not limited to, completion of the Hanford Site Solid (Radioactive and Hazardous) Waste Program Environmental Impact Statement (SW EIS), resolving equity issues associated with the receipt of offsite MLLW, and verification that the candidate waste streams meet the Hanford Site Waste Acceptance Criteria (WAC). The ROD for the SW EIS is expected in 2002, equity discussions are ongoing, and waste acceptance criteria are already established and can be used to determine acceptability.

Book Topical Report on Release Scenario Analysis of Long term Management of High level Defense Waste at the Hanford Site

Download or read book Topical Report on Release Scenario Analysis of Long term Management of High level Defense Waste at the Hanford Site written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Potential release scenarios for the defense high-level waste (HLW) on the Hanford Site are presented. Presented in this report are the three components necessary for evaluating the various alternatives under consideration for long-term management of Hanford defense HLW: identification of scenarios and events which might directly or indirectly disrupt radionuclide containment barriers; geotransport calculations of waste migration through the site media; and consequence (dose) analyses based on groundwater and air pathways calculations. The scenarios described in this report provide the necessary parameters for radionuclide transport and consequence analysis. Scenarios are categorized as either bounding or nonbounding. Bounding scenarios consider worst case or what if situations where an actual and significant release of waste material to the environment would happen if the scenario were to occur. Bounding scenarios include both near-term and long-term scenarios. Near-term scenarios are events which occur at 100 years from 1990. Long term scenarios are potential events considered to occur at 1000 and 10,000 years from 1990. Nonbounding scenarios consider events which result in insignificant releases or no release at all to the environment. Three release mechanisms are described in this report: (1) direct exposure of waste to the biosphere by a defined sequence of events (scenario) such as human intrusion by drilling; (2) radionuclides contacting an unconfined aquifer through downward percolation of groundwater or a rising water table; and (3) cataclysmic or explosive release of radionuclides by such mechanisms as meteorite impact, fire and explosion, criticality, or seismic events. Scenarios in this report present ways in which these release mechanisms could occur at a waste management facility. The scenarios are applied to the two in-tank waste management alternatives: in-situ disposal and continued present action.
