Pressurized Fluidized-Bed Hydroretorting of eastern oil shales. Final report, June 1992--January 1993
The Devonian oil shales of the Eastern United States are a significant domestic energy resource. The overall objective of the multi-year program, initiated in September 1987 by the US Department of Energy was to perform the research necessary to develop the pressurized fluidized-bed hydroretorting (PFH) process for producing oil from Eastern oil shales. The program also incorporates research on technologies in areas such as raw shale preparation, beneficiation, product separation and upgrading, and waste disposal that have the potential of improving the economics and/or environmental acceptability of recovering oil from oil shales using the PFH process. The program was divided into the following active tasks: Task 3 -- Testing of Process Improvement Concepts; Task 4 -- Beneficiation Research; Task 6 -- Environmental Data and Mitigation Analyses; and Task 9 -- Information Required for the National Environmental Policy Act. In order to accomplish all of the program objectives, tho Institute of Gas Technology (ICT), the prime contractor, worked with four other institutions: The University of Alabama/Mineral Resources Institute (MRI), the University of Alabama College of Engineering (UA), University of Kentucky Center for Applied Energy Research (UK-CAER), and Tennessee Technological University (TTU). This report presents the work performed by IGT from June …

The potential of PCB photochemistry at Moccasin Bend
The TVA/EPRI Tailored Collaborative Project {open_quotes}Biotransformation of Polychlorinated Biphenyls (PCBS) in Contaminated Soils{close_quotes}, has as its objective biotransformation of PCB contaminated soils at utility sites (Phase I Report March 1992). However, there is recognition of the existence of other types of nonmetabolic alterations of PCBs in the contaminated soils. Of these nonmetabolic alterations, photoalteration is of special interest to the project. Photoalteration has the potential for enhancing PCB transformation with little intervention and little harm to the microbial community. PCBs have pervaded the environment, and the paucity of knowledge about their chemistry is becoming readily apparent. Although PCBs are quite resistant to degradation, photolysis, which is a chemical decomposition process that is induced by radiant energy, may be important in the environmental chemistry of PCBS. The photochemical degradation of PCBs may affect atmospheric levels of contaminants and photolabile chemicals that reside in water bodies or on surfaces, as for example, on leaves and vegetation. Chemicals present in the environment can undergo direct or indirect phototransformation which includes photosensitized degradation and oxygenation as well as photoinduced degradation. Photoalteration is produced by either artificial light or by light from the sun. Ultraviolet radiation (UV) is known to induce chemical reactions in many …

New directions at TVA with special reference to agricultural research
Public Support for the Tennessee Valley Authority`s (TVA) fertilizer research and development program in Muscle Shoals, Alabama, ended in fiscal year 1993. TVA`s research center at Muscle Shoals, formerly known as the National Fertilizer and Environmental Research Center, is now the TVA Environmental Research Center. Efforts at the Center have diversified to include research and support areas of Agricultural Research and Practices, Atmospheric Sciences, Biotechnology, Waste Management, and Remediation, Environmental Site Remediation, Support Services, Environmental Management, and Technology Transfer. ``We`re building on the expertise and success of our earlier research and focusing our new projects on emerging problems of the 21st century,`` TVA`s Chairman Craven Crowell said in prepared remarks to Congress on March 2, 1994. Agricultural Research in TVA has been aligned with corporate objectives to develop solutions to environmental problems of regional, national and international significance because the agency`s business incorporates a broad mix of responsibilities, including power generation, navigation, flood control, shoreline management, recreation, environmental research, and economic development. Agricultural strategies for watershed protection lie at the core of TVA`s new agricultural research agenda. The major influences for this agenda are TVA`s direct stewardship responsibilities for the 60,000 miles of streams that feed the 652-mile-long Tennessee River; …

10-MW demonstration of the gas suspension absorption process at TVA`s Center for Emissions Research. Final report
The Tennessee Valley Authority (TVA) in cooperation with AirPol Inc., and the U.S. Department of Energy (DOE), has recently completed a successful 17-month test program with the AirPol Gas Suspension Absorption (GSA) flue gas desulfurization (FGD) process at TVA`s Center for Emissions Research (CER). This project was selected by DOE for funding in the third round of the Clean Coal Technology Program. This 10-MW demonstration of the GSA FGD system at the CER was the first application of this technology in the U.S. The GSA test program, which was cofunded two-thirds by TVA and one-third by DOE/AirPol, was completed over a 17-month period from November 1, 1992 to March 31, 1993. This test program demonstrated that the GSA FGD technology could achieve high SO{sub 2} removal efficiencies (90+ percent) for a 2.7 percent sulfur (as-fired) coal application, while maintaining particulate emissions below the New Source Performance Standards (NSPS), i.e., 0.03 lb/MBtu, in a four-field electrostatic precipitator. The reliability and operability of this system was also demonstrated in a 28-day, 24 hour/day, continuous run during which the GSA unit simultaneously achieved high SO{sub 2} removal efficiencies (90+ percent) and maintained particulate emissions below the NSPS. Also, the air toxics removal capabilities …

Avoidance of Thermal Effluent by Juvenile Chinook Salmon (Oncorhynchus Tshowytscha) and Its Implications in Waste Heat Management
Knowledge of behavioral responses of aquatic organisms to thermal discharges at power plants is essential to evaluate thermal exposure and subsequent effects on survival and ecological success. Instantaneous responses of juvenile salmon that encountered a simulated river-thermal plume interface were assessed in a model raceway with a thermal discharge. Fish movement and response to the discharge were recorded on videotape. Juvenile chinook salmon (Oncorhynchus tshawytscha) tested under three discharge conditions (no plume, ambient plume and heated plume) avoided plume temperatures greater than 9 to 11/sup 0/C above ambient. Fish occasionally oriented to the discharge current, but were not attracted to the thermal component of the plume when plume ..delta..T's were below the avoidance level of 11/sup 0/C. Fish did not pass to the lower end of the raceway when plume ..delta..T exceeded 9 to 11/sup 0/C. The responses noted in our experiments suggest organismic behavior may prevent juvenile salmon in nature from experiencing lethal conditions from thermal discharges and have application in waste heat management and utilization.

Automated Corrosion System in a Moist Environment
In an effort to assist researchers investigating the moisture-generated corrosion of metals and ceramics, a unique exposure system was developed. The initial goal of this system was to monitor corrosion ranging from a few monolayers at the outset of the corrosion process to high mass gains in more extensively corroded material. The new system uses a small robot arm for sample manipulation; gravimetric and Fourier transform infrared (FTIR) spectroscopy for corrosion-product determination; and a gas blending system to control the moisture content of the glove box in which the system is housed. The system's computer control can be configured to coordinate the examination of as many as 20 samples by periodic weighing and FTIR scanning. The computer also performs such functions as data logging of the temperature and pressure of the system and of the flow rate and moisture content of the purge gas. One main benefit of the computer-controlled robotic system is its ability to monitor samples 2 4 hours a day with precision control; this reduces problems stemming from human error or inconsistency of human technique.

Addition of Tomographic Capabilities to NMIS
This paper describes tomographic capabilities for the Nuclear Materials Identification System (NMIS). The tomographic capabilities add weapons component spatial and material properties information that result in a more detailed item signature (template) and provide more information for physical attributes analyses. The Nuclear Materials Identification System (NMIS) is used routinely to confirm the identity of HEU components in sealed containers. It does this through a radiation signature acquired by shining a {sup 252}Cf source through the container and measuring the radiation at four detectors stacked vertically on the other side. This measurement gives a gamma and neutron radiation transmission profile of the weapons component, mixed with the radiation production due to the induced fissions in the fissile materials. This information is sufficient to match an "unknown" weapons component signature to a template signature from a reference item when measuring under controlled conditions. Tomography measures the interior of an item by making transmission measurements from all angles around the item, whereas NMIS makes the measurements from a single angle. Figure 1 is a standard example of tomographic reconstruction, the Shepp-Logan human brain phantom. The measured quantity is attenuation so high values (white) are highly attenuating areas.

Agreement to Provide Energy Planning, Analysis, and Evaluation
Three separate subjects are analyzed: (1) the incremental pricing requirements of LNG projects, (2) cooperative Arab/Israeli energy programs based on natural gas, and (3) the effects of the 1978 Natural Gas Policy Act on the country as a whole and particularly on Illinois, Michigan, Wisconsin, and Minnesota. The studies found that (1) incremental pricing of LNG complicates the financing of LNG projects and reduces the number of viable projects, leading to increased oil and LP-gas imports, (2) cooperative gas-utilization ventures between Egypt and Israel should aim at developing a regional pipeline network, constructing export facilities, and producing chemical feedstocks, and (3) the peculiarities of each region of the US, along with the interdependency of the factors involved in assessing the NGPA's impact on each region, complicate any attempt to quantify the act's effects, but the profile constructed for Region 5 will facilitate quantification when more data become available.
