Mobile worksystems for decontamination and decommissioning operations. Final report

This project is an interdisciplinary effort to develop effective mobile worksystems for decontamination and decommissioning (D&D) of facilities within the DOE Nuclear Weapons Complex. These mobile worksystems will be configured to operate within the environmental and logistical constraints of such facilities and to perform a number of work tasks. Our program is designed to produce a mobile worksystem with capabilities and features that are matched to the particular needs of D&D work by evolving the design through a series of technological developments, performance tests and evaluations. The Phase I effort was based on a robot called the Remote Work Vehicle (RWV) that was previously developed by CMU for use in D&D operations at the Three Mile Island Unit 2 Reactor Building basement. During Phase I of this program, the RWV was rehabilitated and upgraded with contemporary control and user interface technologies and used as a testbed for remote D&D operations. We established a close working relationship with the DOE Robotics Technology Development Program (RTDP). In the second phase, we designed and developed a next generation mobile worksystem, called Rosie, and a semi-automatic task space scene analysis system, called Artisan, using guidance from RTDP. Both systems are designed to work with and complement other RTDP D&D technologies to execute selective equipment removal scenarios in which some part of an apparatus is extricated while minimally disturbing the surrounding objects. RTDP has identified selective equipment removal as a timely D&D mission, one that is particularly relevant during the de-activation and de-inventory stages of facility transitioning as a means to reduce the costs and risks associated with subsequent surveillance and monitoring. In the third phase, we tested and demonstrated core capabilities of Rosie and Artisan; we also implemented modifications and enhancements that improve their relevance to DOE`s facility transitioning mission.

Three-dimensional subsurface imaging synthetic aperture radar (3D SISAR). Final report, September 22, 1993--September 22, 1996

The concept developed under this applied research and development contract is a novel Ground Penetrating Radar system capable of remotely detecting, analyzing, and mapping buried waste containers from a mobile platform. From the testing and analysis performed to date, the 3-D SISAR has achieved the detection, accurate location, and three-dimensional imaging of buried test objects from a stand-off geometry. Tests have demonstrated that underground objects have been located to within 0.1 meter of their actual position. This work validates that the key elements of the approach are performing as anticipated. The stand-off synthetic aperture radar (SAR) methodology has been demonstrated to be a feasible approach as a remote sensing technique. The radar sensor constructed under this project is providing adequate quality data for imaging, and the matched filters have been demonstrated to provide enhanced target detection. Additional work is on-going in the area of underground propagation and scattering phenomena to provide enhanced depth performance, as the current imaging results have been limited to a few feet of depth underground.

The atlas of major Appalachian gas plays. Final report

This project will evaluate the technical, economic and environmental feasibility of filling abandoned underground mine voids with alkaline, advanced coal combustion wastes. Both pneumatic and hydraulic injection methods will be investigated. Success will be measured in terms of technical feasibility of the approach (i.e. % void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). Phase 1 is concerned with the development of the grout and a series of predictive models. Phase 1 will also redesign a pneumatic ejector, that was developed to stow limestone, to efficiently stow FBC ash. Phase 2 is a small scale field test at Anker Energy`s Fairfax mine. An inactive panel will be used to evaluate flow, strength, and pressure requirements for hydraulic (grout) injection. The Phase 2 pneumatic injection activities will take place at an Anker Energy mine in Preston County, West Virginia. Air flow requirements, pressure requirements, stowing rate (tons per hour), and stowing efficiency (distance blown) will be determined. Phase 3 is to take 26 months and will be a full scale test at Anker`s eleven acre Long Ridge mine site. The mine will be filled using both pneumatic and hydraulic injection methods. It is expected that the FBC ash will replace what is now an acid mine pool with an alkaline solid so that the ground water will tend to flow around rather than through the previously mined areas. The project will demonstrate whether FBC ash can be successfully disposed of in underground mines.

Advanced sorbent development program. Annual report, November 1, 1994--November 30, 1995

The overall objective of this program is to develop regenerable sorbents for hydrogen sulfide removal from coal-derived fuel gases in the temperature range 343--538 C. Two categories of reactor configurations are being considered: fixed-bed/moving-bed reactors and fluidized-bed (bubbling and circulating) reactors. In addition, a cost assessment and a market plan for large-scale fabrication of sorbents will be developed. As an optional task, a long-term bench-scale testing (100 cycles) of the best fixed-bed/moving-bed and fluidized-bed sorbents will be conducted. The sorbents will have chemical characteristics that permit cyclic regeneration over many cycles without a drastic loss of activity. They must also have physical characteristics that are compatible with the selected reactor, e.g., fixed vs. fluidized bed, and which remain acceptable during absorption and regeneration. The sorbents must be capable of reducing the hydrogen sulfide level in the fuel gas to less than 20 ppmv in the specified temperature range and pressures in the range of 1 to 20 atmospheres. The proposed program is divided into several tasks: NEPA Report; Sorbent Preparation; Provision of Bench Unit; Bench Testing; Sorbent Cost Assessment; Topical Report; Market Plan; and Long-Term Testing. Progress on each of these is described.

Geological and petrophysical characterization of the Ferron Sandstone for 3-D simulation of a fluvial-deltaic reservoir. Quarterly progress report, October 1, 1997--December 31, 1997

The objective of this project is to develop a comprehensive, interdisciplinary, and quantitative characterization of a fluvial-deltaic reservoir which will allow realistic inter-well and reservoir-scale modeling to be constructed for improved oil-field development in similar reservoirs world-wide. The geological and petrophysical properties of the Cretaceous Ferron Sandstone in east-central Utah will be quantitatively determined. Both new and existing data will be integrated into a three-dimensional representation of spatial variations in porosity, storativity, and tensorial rock permeability at a scale appropriate for inter-well to regional-scale reservoir simulation. Results could improve reservoir management through proper infill and extension drilling strategies, reduction of economic risks, increased recovery from existing oil fields, and more reliable reserve calculations. Transfer of the project results to the petroleum industry is an integral component of the project.

Task 23 -- User`s guide to GRI-ShowFlow

GRI-ShowFlow is a compilation of flow and transport groundwater models under one user-friendly, graphical interface in the Microsoft{reg_sign}Windows{trademark} 3.1 environment. The groundwater models as well as the interface were derived from existing codes. The motivation behind the development of GRI-ShowFlow was twofold: (1) there is a need to compare and assess various analytical and screening-level models that are being used by regulatory agencies and (2) there is a need for the nonexpert to be able to use these screening-level models and the resulting information without expert interpretation. GRI-ShowFlow was developed for use by gas industry environmental staff who may have little experience with hydrogeology or groundwater models but must be able to quickly determine whether there is sufficient chance of groundwater contamination and whether a site does or does not require a more extensive examination. Special attention was therefore given to the Help System in GRI-ShowFlow, which aids the development of the minimal amount of data required by the program and the interpretation of the resulting data. The objective of GRI-ShowFlow is to bring together the existing EPA models in a user-friendly environment and to compare them to each other as well as to new models that contain analytical solutions to three-dimensional source descriptions. A three-dimensional body will more closely reflect the shapes of contaminant sources than one- or two-dimensional geometries. In the real world, contamination sources such as landfills, storage pits, and lagoons will, after all, occupy a three-dimensional space.

Houdini{trademark}: Reconfigurable in-tank mobile robot. Final report, June 1995--January 1997

This report details the development of a reconfigurable in-tank robotic cleanup system called Houdini{trademark}. Driven by the general need to develop equipment for the removal of radioactive waste from hundreds of DOE waste storage tanks and the specific needs of DOE sites such as Oak Ridge National Laboratory and Fernald, Houdini{trademark} represents one of the possible tools that can be used to mobilize and retrieve this waste material for complete remediation. Houdini{trademark} is a hydraulically powered, track driven, mobile work vehicle with a collapsible frame designed to enter underground or above ground waste tanks through existing 24 inch riser openings. After the vehicle has entered the waste tank, it unfolds and lands on the waste surface or tank floor to become a remotely operated mini-bulldozer. Houdini{trademark} utilizes a vehicle mounted plow blade and 6-DOF manipulator to mobilize waste and carry other tooling such as sluicing pumps, excavation buckets, and hydraulic shears. The complete Houdini{trademark} system consists of the tracked vehicle and other support equipment (e.g., control console, deployment system, hydraulic power supply, and controller) necessary to deploy and remotely operate this system at any DOE site. Inside the storage tanks, the system is capable of performing heel removal, waste mobilization, waste size reduction, and other tank waste retrieval and decommissioning tasks. The first Houdini{trademark} system was delivered on September 24, 1996 to Oak Ridge National Laboratory (ORNL). The system acceptance test was successfully performed at a cold test facility at ORNL. After completion of the cold test program and the training of site personnel, ORNL will deploy the system for clean-up and remediation of the Gunite storage tanks.

Encoal mild coal gasification project: Encoal project final report, July 1, 1997--July 31, 1997

This document is the summative report on the ENCOAL Mild Coal Gasification Project. It covers the time period from September 17, 1990, the approval date of the Cooperative Agreement between ENCOAL and the US Department of Energy (DOE), to July 17, 1997, the formal end of DOE participation in the Project. The Cooperative Agreement was the result of an application by ENCOAL to the DOE soliciting joint funding under Round III of the Clean Coal Technology Program. By June 1992, the ENCOAL Plant had been built, commissioned and started up, and in October 1994, ENCOAL was granted a two-year extension, carrying the project through to September 17, 1996. No-cost extensions have moved the Cooperative Agreement end date to July 17, 1997 to allow for completion of final reporting requirements. At its inception, ENCOAL was a subsidiary of Shell Mining Company. In November 1992, Shell Mining Company changed ownership, becoming a subsidiary of Zeigler Coal Holding Company (Zeigler) of Fairview Heights, Illinois. Renamed successively as SMC Mining Company and then Bluegrass Coal Development Company, it remained the parent entity for ENCOAL, which has operated a 1,000-ton/day mild coal gasification demonstration plant near Gillette, Wyoming for nearly 5 years. ENCOAL operates at the Buckskin Mine owned by Triton Coal Company (Triton), another Zeigler subsidiary.

Advanced sulfur control concepts in hot-gas desulfurization technology. Quarterly report, January 1, 1996--March 31, 1996

The last experimental tests involving FeS regeneration in both the atmospheric pressure and high pressure electrobalance reactors were completed during the quarter. The effects of temperature, reactant composition, and flow rate were studied in the atmospheric pressure electrobalance in atmospheres of O{sub 2}/N{sub 2}, H{sub 2}O/N{sub 2}, and O{sub 2}/H{sub 2}O/N{sub 2}. The same parameters plus pressure were studied in the high pressure electrobalance. Essentially all runs were carried out at volumetric flow rates sufficiently large to eliminate external mass transfer resistance. The initial regeneration rate was found to be a weak function of temperature and to be first-order in both O{sub 2} and H{sub 2}O. In tests involving both O{sub 2} and H{sub 2}O, the initial reaction rate was equal to the sum of the individual rates involving O{sub 2} only and H{sub 2}O only. The effect of pressure on the initial reaction rates in high pressure tests was somewhat unexpected in that the initial rate increased with pressure between 1 and 5 atm, and subsequently decreased between 5 and 15 atm. Statistical analysis and correlation of the electrobalance data have been completed and results are presented in this report. Equations for the initial rate of regeneration of FeS in O{sub 2} and H{sub 2}O as a function of temperature and reactive gas concentration have been developed. Slow progress has been made with the fixed-bed reactor. A number of reactor scoping tests involving FeS regeneration in O{sub 2} and H{sub 2}O, and CeO{sub 2} sulfidation in H{sub 2}S were completed during the quarter. Chromatographic product gas analysis is now working reliably. Final repairs on the PMT temperature controller for the Antek total sulfur analyzer were completed and the unit seems to be functioning as expected. The Antek and GC responses in FeS regeneration runs in which all sulfur should be liberated as SO{sub 2} tracked reasonably well.

Environmental Management Technology Leveraging Initiative. Topical report, October 1, 1995--September 30, 1996

The ``Environmental Management Technology Leveraging Initiative,`` a cooperative agreement between the Global Environment and Technology Foundation and the Department of Energy-Morgantown Energy Technology Center, has completed its second year. This program, referred to as the Global Environmental Technology Enterprise (GETE) is an experiment to bring together the public and private sectors to identify, formulate, promote and refine methods to develop more cost-effective clean-up treatments. Working closely with Department of Energy officials, National Laboratory representatives, business people, academia, community groups, and other stakeholders, this program attempts to commercialize innovative, DOE-developed technologies. The methodology to do so incorporates three elements: business assistance, information, and outreach. A key advance this year was the development of a commercialization guidance document which can be used to diagnose the commercialization level and needs for innovative technologies.

Task 50 - deposition of lignites in the Fort Union Group and related strata of the northern Great Plains

Late Cretaceous, Paleocene, and early Eocene geologic and paleontologic studies were undertaken in western North Dakota, eastern and south-central Montana, and northwestern and northeastern Wyoming. These study areas comprise the Williston, Bighorn, and Powder River Basins, all of which contain significant lignite resources. Research was undertaken in these basins because they have the best geologic sections and fossil record for the development of a chronostratigraphic (time-rock) framework for the correlation of lignite beds and other economic resources. A thorough understanding of the precise geologic age of the deposition of sediments permits a powerful means of interpreting the record of geologic events across the northern Great Plains. Such an understanding allows for rigorous interpretation of paleoenviromnents and estimates of resource potential and quality in this area of economically significant deposits. This work is part of ongoing research to document change in the composition of molluscan fossil faunas to provide a paleoenvironmentally sensitive independent means of interpreting time intervals of brief duration during the Late Cretaceous, Paleocene, and Eocene. This study focuses on the record of mollusks and, to a lesser extent, mammals in the (1) Hell Creek-Tullock Formations, which include the Cretaceous-Paleocene boundary, in the western portion of the Williston Basin, Montana; (2) uppermost Cretaceous, Paleocene, and lowermost Eocene strata in western North Dakota, which -includes the last interior seaway in North Dakota; (3) upper Paleocene and lowermost Eocene of the northern portion of the Bighorn Basin of south-central Montana and northwestern Wyoming; and (4) Powder River Basin of northeastern Wyoming and southeastern Montana. The geologic record provides different physical and paleontological information to aid in interpreting the geologic record through the study interval.

LTC vacuum blasting maching (concrete): Baseline report: Greenbook (Chapter)

The LTC shot blast technology was tested and is being evaluated at Florida International University (FIU) as a baseline technology. In conjunction with FIU`s evaluation of efficiency and cost, this report covers the evaluation conducted for safety and health issues. It is a commercially available technology and has been used for various projects at locations throughout the country. The LTC 1073 Vacuum Blasting Machine uses a high-capacity, direct-pressure blasting system which incorporates a continuous feed for the blast media. The blast media cleans the surface within the contained brush area of the blast. It incorporates a vacuum system which removes dust and debris from the surface as it is blasted. The safety and health evaluation during the testing demonstration focused on two main areas of exposure: dust and noise. Dust exposure during maintenance activities was minimal, but due to mechanical difficulties dust monitoring could not be conducted during operation. Noise exposure was significant. Further testing for each of these exposures is recommended because of the outdoor environment where the testing demonstration took place. This may cause the results to be inaccurate. It is feasible that the dust and noise levels will be higher in an enclosed environment. In addition, other safety and health issues found were ergonomics, heat stress, tripping hazards, electrical hazards, lockout/tagout, and arm-hand vibration.
