AFBC Roadbed Project groundwater data

Description: TVA permitted the use of AFBC material in a section of roadbed at Paducah, Kentucky, for the purpose of demonstrating its usability as a roadbed base. To determine if the material would leach and contaminate groundwater, four wells and seven lysimeters were installed beside and in the roadbed base material. In August 1991, TVA Field Engineering visited the AFBC Roadbed Project to collect samples and water quality data. The goal was to collect samples and data from four wells and seven lysimeter… more

Carbon dioxide, climate and the deep ocean circulation: Carbon chemistry model

Description: The objective of this study was to investigate the role of oceanic carbon chemistry in modulating the atmospheric levels of CO[sub 2]. It is well known that the oceans are the primary sink of the excess carbon pumped into the atmosphere since the beginning of the industrial period. The suspended particulate and the dissolved organic matters in the deep ocean play important roles as carriers of carbon and other elements critical to the fate of CO[sub 2]. In addition, the suspended particulate ma… more

Characterization of high-power RF structures using time-domain field codes

Description: We have modeled gyrotron windows and gyrotron amplifier sever structures for TE modes in the 100--150 GHz range and have computed the reflection and transmission characteristics from the field data. Good agreement with frequency domain codes and analytic analysis have been obtained for some simple geometries. We present results for realistic structures with lossy coatings and describe implementation of microwave diagnostics.

Chemical interactions in multimetal/zeolite catalysts

Description: Research is proposed on two groups of zeolite based catalysts that contain two transition elements. In one group both metals are fully reduced, in the other group one element is left as a positive ion; it can act as a chemical anchor'', or as a catalyst promoter for the reduced metal. The objective is to explore the potential of such materials for designing superior catalysts for synthesis and conversion of hydrocarbons and other energy carriers. ENDOR, EXAFS, CO-FTIR and TPD will be used to id… more

Configurational diffusion of asphaltenes in fresh and aged catalyst extrudates

Description: The objective of this research is to determine the relationship between the size and shape of coal and petroleum macromolecules and their diffusion rates i.e., effective diffusivities, in catalyst pore structures. That is, how do the effective intrapore diffusivities depend on molecule configuration and pore geometry.

Deforestation: An Overview of Global Programs and Agreements

Description: In recent years, global environmental concerns have figured prominently on the American political agenda. In particular, tropical deforestation and its implications for global climate change and biological diversity loss have prompted public outcry. Concerns have since grown to include other forest types as well. The Congress has considered a variety of legislation to stem the tide of increasing deforestation and the United States has supported a number of bilateral and multilateral initiatives… more

Guidebook for Farmstead Demand-Side Management (DSM) program design

Description: The acceptance and growth of Demand-Side Management (DSM) continues to increase in the US. According to latest estimates, total expenditures on electric utility DSM programs now exceed $1.2 billion annually, with these investments ranging from 1 to 5 percent of a utility's gross revenues. In addition, due to increasing environmental concerns and the high cost of new capacity, these expenditure levels are expected to increase. While the vast majority of these DSM programs are directed at the mor… more

Hazardous metals in yellow items used in RCAs

Description: Yellow items used in Radiologically Controlled Areas (RCAs) that could contain hazardous metals were identified. X-ray fluorescence analyses indicated that thirty of the fifty-two items do contain hazardous metals. It is important to minimize the hazardous metals put into the wastes. The authors recommend that the specifications for all yellow items stocked in Stores be changed to specify that they contain no hazardous metals.

The impact of changing land use, nitrate deposition and CO sub 2 fertilization on soil carbon storage

Description: This research strives to assess the impact of changing land use, nitrate deposition and CO{sub 2} fertilization on soil carbon storage. Our motivation is that this reservoir is the most likely candidate for the so-called missing carbon sink. We are working on several aspects of this problem by measuring carbon content, nitrogen content and radiocarbon ratios in paired soil samples from neighboring sites, to determine the impact of land use on soil carbon inventories and turnover times. We are a… more
