100-D Ponds groundwater quality assessment

Description: The 100-D Ponds facility is regulated under the Resource Conservation and Recovery Act of 1976. The pH of groundwater in a downgradient well is statistically different than local background, triggering an assessment of groundwater contamination under 40 CFR 265.93. Results of a similar assessment, conducted in 1993, show that the elevated pH is caused by the presence of alkaline ash sediments beneath the ponds, which are not part of the RCRA unit. The 100-D Ponds should remain in indicator eval… more

Aerogel derived catalysts

Description: Aerogels area class of colloidal materials which have high surface areas and abundant mesoporous structure. SiO{sub 2} aerogels show unique physical, optical and structural properties. When catalytic metals are incorporated in the aerogel framework, the potential exists for new and very effective catalysts for industrial processes. Three applications of these metal-containing SiO{sub 2} aerogels as catalysts are briefly reviewed in this paper--NO{sub x} reduction, volatile organic compound dest… more

Am/Cm Oxalate Precipitation and Washing Demonstration

Description: The purpose of this report is to discuss the findings of the Am/Cm Oxalate Precipitation and Washing Demonstration carried out at TNX during December 1995. This demonstration consisted of two steps: oxalate precipitation and precipitate washing. The first step reacted Am/Cm stimulant solution with oxalic acid resulting in the formation of insoluble lanthanide oxalates and soluble metal oxalates. The second step consisted of washing the precipitate with equal volumes of a nitric acid/oxalic acid… more

Applied grinding wheel performance evaluation for optical fabrication

Description: We are collaborating with the Center for Optics Manufacturing (Rochester NY) to develop fine diamond grinding wheels for spherical grinding of glass optics. A standardized method for evaluating wheel performance includes in-process acoustic emission (AE). This paper includes recent AE measurements taken during the evaluation of several fine diamond grinding wheels and discusses how this new information might relate to the physical performance of the wheels. An interesting observation is also re… more

Audit of groundwater remediation plans at the Savannah River Site

Description: The Department of Energy was required to reduce groundwater contamination that represented a risk to human health or the environment. To achieve this goal, the Savannah River Operations Office (Savannah River) entered into several formal agreements with Federal and State regulators. The agreements described how Savannah River would reduce the level of contamination until the risks to human health and the environment were lowered to an acceptable level. The agreements called for decreasing groun… more

Bulk metallic glass formation in the Pd-Ni-P and Pd-Cu-P alloy systems

Description: Bulk metallic glasses were prepared in the Pd-Ni-P and Pd-Cu-P systems using a fluxing technique. The formation of bulk amorphous Pd-Cu-P alloys was reported here for the first time. For both alloy systems, bulk glass formation requires maintaining the phosphorus content near 20 at.%. In the Pd-Ni-P system, 10-mm diameter amorphous Pd{sub x}Ni{sub 80{minus}x}P{sub 20} rods can be formed for 25 {le} x {le} 60. In the Pd-Cu-P system, 7-mm diameter amorphous Pd{sub x}Cu{sub 80{minus}x}P{sub 20} ro… more

Cesium determination for the DWPF off-gas system performance test

Description: In an effort to determine the cesium decontamination factors (DF`s) of the Defense Waste Processing Facility (DWPF) melter off-gas system at the Savannah River Site, the system was verified during an off-gas performance test. The off-gas performance test occurred during the DWPF waste Qualification Campaigns, WP-16 and WP-17. The verification of the off-gas system, which eliminated the need for a startup test involving a radioactive cesium addition, was based on the analysis of nonradioactive c… more

China-U.S.-Taiwan Economic Relations

Description: Recent political and military tensions between China and Taiwan have focused new attention on U.S. economic interests in the region. The volume of trade and investment between the United States and Taiwan and China has soared during the last 10 years. This trend has helped forge closer ties between the United States and the two economies, but has also been the source of friction. U.S. economic relations with China and Taiwan are likely to be of concern to Congress during the annual debate over … more

China's Changing Conditions

Description: Congressional interest in the leadership change and economic transformation underway in China has grown substantially over the past few years. Leading congressional concerns focus on how economic conditions in China pose opportunities for U.S. enterprise and how the evolution of conditions in China fosters U.S. security, economic, and political interests. Congressional concern with China grew in 1995 and 1996 as a result of reports of the serious decline in the health of senior Chinese leader D… more

Cold vacuum drying facility site evaluation report

Description: In order to transport Multi-Canister Overpacks to the Canister Storage Building they must first undergo the Cold Vacuum Drying process. This puts the design, construction and start-up of the Cold Vacuum Drying facility on the critical path of the K Basin fuel removal schedule. This schedule is driven by a Tri-Party Agreement (TPA) milestone requiring all of the spent nuclear fuel to be removed from the K Basins by December, 1999. This site evaluation is an integral part of the Cold Vacuum Dryin… more

Comparison of non-thermal plasma techniques for abatement of volatile organic compounds and nitrogen oxides

Description: Non-thermal plasma processing is an emerging technology for the abatement of dilute concentrations of volatile organic compounds (VOCs), nitrogen oxides (NO{sub x}) and other hazardous air pollutants (HAPs) in atmospheric-pressure gas streams. Either electrical discharge or electron beam methods can produce these plasmas. Recent laboratory-scale experiments show that the electron beam method is remarkably more energy efficient than competing non-thermal plasma techniques based on pulsed corona … more

A comprehensive computing initiative for MFE. Revision 1

Description: The authors propose that a national initiative by launched to develop a comprehensive simulation facility for MFE. The facility would consist of physics codes developed by the national MFE community tightly but flexibly coupled through a programmable shell, enabling effectively simultaneous solution of the models in the various codes. The world ``facility`` is chosen to convey the notion that this is where one would go to conduct numerical experiments, using a full set of modules to describe an… more

Conceptual design for a neutron imaging system for thick target analysis operating in the 10-15 MeV energy range

Description: Fast neutron imaging offers the potential to be a powerful non- destructive inspection tool for evaluating the integrity of thick sealed targets. This is particularly true in cases where one is interested in detecting voids, cracks or other defects in low-Z materials (e.g. plastics, ceramics, salts, etc.) which are shielded by thick, high-Z parts. In this paper we present the conceptual design for a neutron imaging system for use in the 10 - 15 MeV energy range and discuss potential application… more

Coresident sensor fusion and compression using the wavelet transform

Description: Imagery from coresident sensor platforms, such as unmanned aerial vehicles, can be combined using, multiresolution decomposition of the sensor images by means of the two-dimensional wavelet transform. The wavelet approach uses the combination of spatial/spectral information at multiple scales to create a fused image. This can be done in both an ad hoc or model-based approach. We compare results from commercial ``fusion`` software and the ad hoc, wavelet approach. Results show the wavelet approa… more
