Book Description
The research and development of new technology in support of the tank waste remediation system (TWRS) program at Hanford is largely driven by the unique situation with the Hanford radioactive tank wastes. The operational history at Hanford has involved three different major processes and several major campaigns to recover fission products from the wastes, and has not maintained a segregation of the high-level wastes. The result is a very diverse inventory with very high content of solids of many different chemical constituents and great complexity. The R & D program must not only assure that an acceptable strategy for remediation of these wastes can be put in place, it must also define ways of improving the cost effectiveness of the strategy to make the mammoth task more tractable.

Book Description
The primary purpose of systems engineering is to organize information and knowledge to assist those who manage, direct, and control the planning, development, production, and operation of the systems necessary to accomplish a given mission. However, this purpose can be compromised or defeated if information production and organization becomes an end unto itself. Systems engineering was developed to help resolve the engineering problems that are encountered when attempting to develop and implement large and complex engineering projects. It depends upon integrated program planning and development, disciplined and consistent allocation and control of design and development requirements and functions, and systems analysis. The key thesis of this report is that proper application of systems analysis and systems engineering will improve the management of tank wastes at the Hanford Site significantly, thereby leading to reduced life cycle costs for remediation and more effective risk reduction. The committee recognizes that evidence for cost savings from application of systems engineering has not been demonstrated yet.

Book Description
As part of the overall Hanford Tank Waste Remediation System (TWRS) Part B Project, BNFL, Inc. has contracted DOE-Westinghouse Savannah River Company's Savannah River Technology Center (SRTC) to provide research and development services in characterization, pretreatment, and immobilization of actual Hanford tank wastes. Additionally, SRTC is developing design basis data using simulants of Handord tank wastes in areas of ion exchange, filtration, precipitation, glass former blending, evaporation, and slurry mixing. This paper will provide an overview of the SRTC TWRS development program.

Book Description
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.

Book Description
The U.S. Department of Energy (DOE) continues to face a major radioactive waste tank remediation problem with hundreds of waste tanks containing hundreds of thousands of cubic meters of high-level waste (HLW) and transuranic (TRU) waste across the DOE complex. Approximately 80 tanks are known or assumed to have leaked. Some of the tank contents have reacted to form flammable gases, introducing additional safety risks. These tanks must be maintained in a safe condition and eventually remediated to minimize the risk of waste migration and/or exposure to workers, the public, and the environment. However, programmatic drivers are more ambitious than baseline technologies and budgets will support. Science and technology development investments are required to reduce the technical and programmatic risks associated with the tank remediation baselines. The Tanks Focus Area (TFA) was initiated in 1994 to serve as the DOEs̀ Office of Environmental Managements̀ (EMs̀) national technology development program for radioactive waste tank remediation. The national program was formed to increase integration and realize greater benefits from DOEs̀ technology development budget. The TFA is responsible for managing, coordinating, and leveraging technology development to support DOEs̀ four major tank sites: Hanford Site (Washington), Idaho National Engineering and Environmental Laboratory (INEEL) (Idaho), Oak Ridge Reservation (ORR) (Tennessee), and Savannah River Site (SRS) (South Carolina). Its technical scope covers the major functions that comprise a complete tank remediation system: waste retrieval, waste pretreatment, waste immobilization, tank closure, and characterization of both the waste and tank with safety integrated into all the functions. The TFA integrates program activities across organizations that fund tank technology development EM, including the Offices of Waste Management (EM-30), Environmental Restoration (EM-40), and Science and Technology (EM-50).
