“…Adsorbent materials need to possess certain critical properties to be designated as a getter material. Several investigators have identified a number of important performance characteristics that getter materials should possess for effective deployment in repository environments (Coons et al 1980;Klingsberg and Duguid 1980;Nowak 1980a;Moak 1981;Viani 1999). Viani (1999) provided the most comprehensive list of criteria that can be used to assess the properties of potential getter materials.…”

Executive SummaryPacific Northwest National Laboratory has initiated a waste-form testing program to support the longterm durability evaluation of a waste form for secondary wastes generated from the treatment and immobilization of Hanford radioactive tank wastes. The purpose of the work discussed in this report is to identify candidate stabilization technologies and getters that have the potential to successfully treat the secondary waste stream liquid effluent, mainly from off-gas scrubbers and spent solids, produced by the Hanford Tank Waste Treatment and Immobilization Plant (WTP). Down-selection to the most promising stabilization processes/waste forms is needed to support the design of a solidification treatment unit (STU) to be added to the Effluent Treatment Facility (ETF). To support key decision processes, an initial screening of the secondary liquid waste forms must be completed by February 2010. Later, more comprehensive and longer term performance testing will be conducted, following the guidance provided by the secondary waste-form selection, development, and performance evaluation roadmap. The resulting waste form will be compliant to regulations and performance criteria and will lead to cost-effective disposal of the secondary wastes.This report starts with a brief review of some of the most commonly used solidification formulations that would be candidates for secondary liquid waste streams. In this review, the available data on performance are discussed, and some preliminary recommendations are provided for materials that should undergo additional screening testing. We also 1) discuss options for disposal of WTP secondary solid waste streams, 2) provide a brief overview of standard regulatory test methods used for measuring contaminant leachability and waste-form physical strength (with emphasis on the U.S. Environmental Protection Agency's [EPA's] new methods as a screening tool for comparing waste solidification materials of interest), and 3) provide an overview of factors that must be considered in long-term performance testing, including state-of-the-art characterization tools that can provide the data needed to technically defend predictive modeling simulations of long-term material behavior. The long-term wasteform testing and solid and leachate characterization must be robust enough to effectively predict material performance in the Integrated Disposal Facility over the 10,000-year period of performance for the engineered system. The solidification technologies for liquid waste streams include cement/grout, containerized Cast Stone, phosphate-bonded ceramics, alkali-aluminosilicate geopolymers, hydroceramics, L-TEM, and fluidized-bed steam reforming (FBSR). In addition to these, other mature technologies and two compounds, namely goethite and sodalite (that are still being developed), that show considerable promise as waste forms or getters are also discussed. It is our recommendation, based upon the available literature, that Cast Stone, chemically bonded phosphate ceramics (Ceramicrete...

“…These barriers, e.g., waste form, canister, buffer, overpack, and backfill ( package. The functions of the different barriers envisaged by Coons et al (1980) involve redundancy to prevent or reduce the effects of premature failure of one or more components of the system (Fig. 1).…”

“…The extent of multiple redundancy in the conceptual waste package is indicated in Table 1 (Coons et al, 1980). After emplacement in the repository, the function of the waste form is to retain the radionuclides; whereas the functions of the canister and remaining engineered barriers vary with time.…”

“…The preceding paragraph summarizes the approach taken by Coons et al (1980) in defining the functions of an engineered barrier system throughout the life of a repository in basalt. These investigators did not, however, make any attempt to estimate performance requirements for the engineered barrier system other than to emphasize that it must meet stringent regulatory criteria (Nuclear Commission, 1980).…”

in Oak Ridge, Tennessee, has been the national center for scientific and technical information for the Department of Energy (DOE) and its predecessor agencies since 1946 In developing and managing DOE's technical information program, the Center places under bibliographic control not only DOE-onginated information but also worldwide literature on scientific and technical advances in the energy field and announces the source and availability of this information Whereas the literature of science is emphasized, coverage is extended to DOE programmatic, socioeconomic, environmental legislative/regulatory, energy analysis, and policy-related areas To accomplish this mission, the Center builds and maintains computerized energyinformation data bases and disseminates this information via computerized retrieval systems and announcement publications such as abstracting journals, bibliographies, and update journals Direct access to the Center's most comprehensive data base, the Energy Data Base, is available to the public through commercial on-line bibliographic retrieval systems The Energy Data Base and many of the Center's energyrelated data bases are available to DOE offices and contractors and to other government agencies via DOE/RECON, the Department's on-line information retrieval system The Center has developed and maintains systems to record and communicate energy-related research-in-progress information, to maintain a register of DOE public communications publications, to track research report deliverables from DOE contractors, and to test and make available DOE-funded computer software programs with scientific and management applications The Center also maintains a full-scale publishing capability to serve special publication needs of the Department To effectively manage DOE's technical information resources, the Center's program is one of continual development and evaluation of new information products, systems, and technologies Donald Paul Hodel DISCLAIMERThis report was prepared as an account of work sponsored by an agency of the United States Government.
