The Savannah River Site's Groundwater Monitoring Program: Fourth quarter 1991

Description: The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site's (SRS) Groundwater Monitoring Program. During fourth quarter 1991, EPD/EMS conducted extensive sampling of monitoring wells. EPD/EMS established two sets of criteria in 1986 to assist in the management of sample results. The flagging criteria do not define contamination levels; instead, they aid personnel in sample scheduling, interpretation of data, and trend identification. … more

Imaging algorithms for geophysical applications of impedance tomography

Description: The methods of impedance tomography may be employed to obtain images of subsurface electrical and conductivity variations. For practical reasons, voltages and currents are usually applied at locations on the ground surface or down a limited number of boreholes, but almost never over the entire surface of the region being investigated. The geophysical inversion process can be facilitated by constructing algorithms adopted to these particular geometries and to the lack of complete surface data. I… more

Slidesurfaces with Adaptive New Definitions (SAND) for transient analysis

Description: This paper describes some recent developments in adaptive contact algorithms for the transient analysis of penetration and material failure. A failure criterion is defined for volumes of potentially failing material on each side of a contact surface. As material within an element fails, the element is removed from the calculation and the contact surface is adaptively redefined to include the newly exposed outer material boundary. This contact algorithm admits arbitrary combinations of shell and… more

A computational model for coal transport and combustion. Quarterly technical progress report, March 1, 1992--May 31, 1992

Description: In the period of March 1, 1992 to May 30, 1992 considerable progress has been made in the development of the stress transport model for rapid granular flows in a rotating frame of reference. The derivation of thermodynamically consistent constitutive equations were complete. It was shown that the model contains the existing kinetics theories as special limiting cases. The model predictions for the special case of rapid simple shear flows were evaluated and the results are compared with the simu… more

Advanced wall-fired boiler combustion techniques for the reduction of nitrogen oxides (NO{sub x}): Low NO{sub x} burner test phase results

Description: This paper discusses the technical progress of a US Department of Energy Innovative Clean Coal Technology project demonstrating advanced wall-fired combustion techniques for the reduction of nitrogen oxide(NO{sub x}) emissions from coal-fired boilers. The primary objective of the demonstration is to determine the performance of two low NO{sub x} combustion technologies applied in a stepwise fashion to a 500 MW boiler. A target of achieving 50 percent NO{sub x} reductions has been established fo… more

Plutonium pyrophoricity

Description: A review of the published literature on ignition and burning of plutonium metal was conducted in order to better define the characteristic of pyrophoric plutonium. The major parameter affecting ignition is the surface area/mass ratio of the sample. Based on this parameter, plutonium metal can be classified into four categories: (1) bulk metal, (2) film and foils, (3) chips and turnings, and (4) powder. Other parameters that can alter the ignition of the metal include experimental, chemical, phy… more

Bus industry market study. Report -- Task 3.2: Fuel cell/battery powered bus system

Description: In support of the commercialization of fuel cells for transportation, Georgetown University, as a part of the DOE/DOT Fuel Cell Transit Bus Program, conducted a market study to determine the inventory of passenger buses in service as of December, 1991, the number of buses delivered in 1991 and an estimate of the number of buses to be delivered in 1992. Short term and long term market projections of deliveries were also made. Data was collected according to type of bus and the field was divided … more
