The purpose of this report is to evaluate the effect of near-field rock treatment by injection of reactive material (calcite) above the drift for the purpose of decreasing postclosure drift seepage. The method used for the calculation was a coupled reaction-transport numerical model for gas-water-rock interaction. This includes the mass conservation of heat, liquid and gas for thermohydrological calculations, of aqueous and gaseous species for advective and diffusive transport, and the kinetics of mineral-water reactions.

In the 106th Congress, no comprehensive activity on reauthorizing the Clean Water Act occurred, although a number of individual clean water bills were enacted. Other issues have been debated recently, such as reforming the law to provide regulatory relief for industry, states and cities, and individual landowners. The debate over many of these issues highlights differing views of the Act and its implementation by some who seek to strengthen existing requirements and others who believe that costs and benefits should be more carefully weighed before additional control programs are mandated.

The objective of the CRADA was to cooperate in the development of a moldable transient suppression polymer composite that can be used to protect electrical equipment and electronics from damage caused by electrical disturbances and faults. The composite was to provide a solid- state means of fault current limitation, particularly for high-current applications. The composite was envisioned to have the following properties: (1) be moldable and therefore suited to the automated manufacture at a low cost; (2) operate with greater speed and reliability than electromechanical devices; and (3) operate in conjunction with appropriately designated mechanical breakers to limit the current and energy under short-circuit fault conditions, thereby providing improved protection to equipment connected to the circuit. The technical work of the project was in part shared between Lockheed Martin and the General Electric Company and in part divided between the participants according to their capabilities. Work was performed in the Oak Ridge K-25, Y-12, and X-10 facilities of Lockheed Martin and at the General Electric Company Corporate Research and Development (GE-CR&D) and Electrical Distribution and Control (GE-ED&C) facilities. Materials were fabricated in facilities of the Y-12 Development. Department, where polymers were filled with varying amounts of conductive materials. However, as …

A series of experiments were conducted in fiscal year 1998 at the Pacific Northwest National Laboratory as part of the Immobilized Low-Activity Waste-Performance Assessment. These experiments evaluated the sorption and transport of uranium, U(VI), under conditions of partial moisture saturation that are relevant to arid region burial sites and vadose-zone far-field conditions at the Hanford Site. The focus was on measuring breakthrough curves (from which distribution coefficient [K{sub d}] values can be calculated) for U(W) in three Hanford Site sediments that represent different texture classes in two unsaturated moisture conditions. Previous research showed that K{sub d} values measured during transport in unsaturated sediments varied with moisture saturation.

The Oak Ridge National Laboratory (OWL) Refinery Yield Model (RYM) has been used to estimate the demand for ethanol in U.S. gasoline production in year 2010. Study cases examine ethanol demand with variations in world oil price, cost of competing oxygenate, ethanol value, and gasoline specifications. For combined-regions outside California summer ethanol demand is dominated by conventional gasoline (CG) because the premised share of reformulated gasoline (RFG) production is relatively low and because CG offers greater flexibility for blending high vapor pressure components like ethanol. Vapor pressure advantages disappear for winter CG, but total ethanol used in winter RFG remains low because of the low RFG production share. In California, relatively less ethanol is used in CG because the RFG production share is very high. During the winter in California, there is a significant increase in use of ethanol in RFG, as ethanol displaces lower-vapor-pressure ethers. Estimated U.S. ethanol demand is a function of the refiner value of ethanol. For example, ethanol demand for reference conditions in year 2010 is 2 billion gallons per year (BGY) at a refiner value of $1.00 per gallon (1996 dollars), and 9 BGY at a refiner value of $0.60 per gallon. Ethanol demand could …

A logical extension of his early work on the path of carbon during photosynthesis, Calvin's studies on the production of hydrocarbons by plants introduced many in the scientific and agricultural worlds to the potential of renewable fuel and chemical feedstocks. He and his co-workers identified numerous candidate compounds from plants found in tropical and temperate climates from around the world. His travels and lectures concerning the development of alternative fuel supplies inspired laboratories worldwide to take up the investigation of plant-derived energy sources as an alternative to fossil fuels.
