Results of screening activities in salt states prior to the enactment of the Nationall Waste Policy Act

Description: The identification of potential sites for a nuclear waste repository through screening procedures in the salt states is a well-established, deliberate process. This screening process has made it possible to carry out detailed studies of many of the most promising potential sites, and general studies of all the sites, in anticipation of the siting guidelines specified in the Nuclear Waste Policy Act. The screening work completed prior to the passage of the Act allowed the Secretary of Energy to … more

Physical response of backfill materials to mineralogical changes in a basalt environment. [Sand-clay mixture containing 25% bentonite]

Description: Backfill materials surrounding waste canisters in a high-level nuclear waste repository are capable of ensuring very slow flow of groundwater past the canisters, and thereby increase the safety of the repository. However, in the design of a repository it will be necessary to allow for possible changes in the backfill. In this experimental program, changes in permeability, swelling behavior, and plastic behavior of the backfill at the temperatures, pressures, and radiation levels expected in a r… more

Treatment of coke-oven wastewater with the powdered activated carbon-contact stabilization activated sludge process. Final report

Description: The objective of the study was to determine optimum parameters for the operation of an innovative process train used in the treatment of coke-over wastewater. The treatment process train consisted of a contact-stabilization activated sludge system with powdered activated carbon (PAC) addition, followed by activated sludge nitrification, followed by denitrification in an anoxic filter. The control and operating parameters evaluated during the study were: (a) the average mixed-liquor PAC concentr… more

Methodology and concepts for the design of surface storage fills at the Anvil Points Oil Shale Retort Facility

Description: Primary obtectives in design of surface disposal fills for processed and raw oil shales are: (a) to insure long-term physical stability, and (b) to prevent surface runoff, surface erosion, and possible subsurface seepage from degrading the water quality of streams and ground water, it was concluded that the analysis and design of spent shale disposal fills should be based on sound geotechnical engineeering principles, considerable experience, and good judgment. An understanding of the source of… more

Salt site performance assessment activities

Description: During this year the first selection of the tools (codes) for performance assessments of potential salt sites have been tentatively selected and documented; the emphasis has shifted from code development to applications. During this period prior to detailed characterization of a salt site, the focus is on bounding calculations, sensitivity and with the data available. The development and application of improved methods for sensitivity and uncertainty analysis is a focus for the coming years act… more

Hydrogeological characterization of Back Forty area, Albany Research Center, Albany, Oregon

Description: Radiological surveys were conducted to determine the potential migration of radionuclides from the waste area to the area commonly referred to as the Back Forty, located in the southern portion of the ARC site. The survey results indicated that parts of the Back Forty contain soils contaminated with uranium, thorium, and their associated decay products. A hydrogeologic characterization study was conducted at the Back Forty as part of an effort to more thoroughly assess radionuclide migration in… more

Trioxane-initiated formic acid denitration

Description: The Savannah River Laboratory has developed a procedure for controlled low-temperature chemical denitration of acidic solutions. The procedure can be used in semi-continuous denitration facilities and can also be directly applied to nitric acid solutions in a storage tank (in situ denitration) if there is some provision for moderate heating (up to 80/sup 0/C) and cooling. The procedure works well for both highly acidic (approx. 11M) and moderately acidic (approx. 3M) solutions. Trioxane, the cy… more

Description: The purpose of this program is to investigate some of the basic physics and chemistry of the electron beam induced NO/sub x/ and SO/sub x/ removal process. The program involves both kinetic modelling and diagnostic development. The development of an adequate kinetic model is necessary in order to scale the laboratory results, which are currently available, to process conditions closer to those that will be encountered at full scale operation. It is also necessary in order to place the laborator… more

Socioeconomic assessment: issues, status, and plans

Description: Numerous public meetings and hearings have been held in Texas, Mississippi, Louisiana and Utah on the issue of siting a nuclear waste repository in salt. Citizens in these potential site areas have raised many questions about how this facility will affect their quality of life. Questions about population and economic changes have been of particular concern. In developing a socioeconomic program, these issues and others have been an integral part of Battelle's socioeconomic studies. The three el… more

Management of defense beta-gamma contaminated solid low-level wastes

Description: In DOE defense operations, approx. 70,000 m/sup 3/ of beta-gamma low-level radioactive waste are disposed of annually by shallow land burial operations at six primary sites. Waste generated at other DOE sites are transported on public roads to the primary sites for disposal. In the practice of low-level waste (LLW) disposal in the US, the site hydrology and geology are the primary barriers to radioactive migration. To date, little emphasis has been placed on waste form improvements or engineere… more
