[Energy and environmental research emphasizing low-rank coal]: Task 5. 8, Development of a coal by-product classification protocol for utilization. Topical report, January--September 1995

Date: October 1, 1995
Creator: Dockter, B.A. & Pflughoeft-Hassett, D.F.
Description: The scope of work for this task was limited to the development of a general process to evaluate coal fly ash for use in applications beyond cement and concrete. Two coal fly ash samples were evaluated for appropriateness in structural fill as an example of how to use alternative classification protocol as ash use standards are developed for the industry. The goal of this project is to develop a classification system for fly ash based on parameters that relate to performance specification of engineering and construction applications. The new classification system will provide a means of evaluating the suitability of coal ash for use in certain products that currently have no reality-based standards or classifications. Recent work by the American Society for Testing and Materials (ASTM) Committee E50 on Pollution Prevention has proposed a standard practice for use of coal ash for structural fill applications. Energy & Environmental Research Center (EERC) coal ash researchers have worked on preparing this standard practice, and the development of criteria for the coal ash to be used in this application will facilitate the use of this standard once approved by ASTM. A preliminary flowchart for classification criteria was developed and is shown in figure ...

Evaluation of decommissioning alternatives for the Pilot Plant Complex, Aberdeen Proving Ground

Date: September 1, 1995
Creator: Rueda, J. & Zimmerman, R.E.
Description: This report presents an evaluation of four decommissioning alternatives for the Pilot Plant Complex (PPC), an inactive chemical weapons research, development, and production facility consisting of nine buildings located in the Edgewood Area of the Aberdeen Proving Ground in Maryland. Decommissioning the PPC involves six steps: (1) assessing existing conditions; (2) dismantling the aboveground portions of the buildings (including the floor slabs, paved roads, and sidewalks within the PPC); (3) reducing the size of the demolition debris and sealing the debris in containers for later testing and evaluation; (4) testing and evaluating the debris; (5) conducting site operation and maintenance activities; and (6) recycling or disposing of the debris with or without prior treatment, as appropriate.

Over-the-road tests of nuclear materials package response to normal environments

Over-the-road tests of nuclear materials package response to normal environments

Date: December 1, 1991
Creator: Gwinn, K.W.; Glass, R.E. & Edwards, K.R.
Description: In support of the development of American National Standards Institute standards for the transport of radioactive materials, Sandia has a program to characterize the normal transport environment. This program includes both analytical modeling of package and trailer responses, and over-the-road tests to measure those responses. This paper presents the results of a series of over-the-road tests performed using Chem-Nuclear equipment in the Barnwell, SC, area. The test events included a variety of road types such as rough concrete, shock events such as railroad grade crossings, and driver responses such as sharp turns. The response of the package and trailer to these events was measured with accelerometers at various locations to determine the inertial loads. Either load cells or strain gages were used to measure tiedown response. These accelerations and loads were measured on systems with flexible and ``rigid`` tiedowns. The results indicated that while significant accelerations occur on the trailer bed, these do not translate into equivalent loads in either the package or the tiedown system. This indicates that trailer-bed response should not be used in determining the load factor for fatigue calculations of the package components or in determining design loads for tiedowns.

Traffic jam dynamics in stochastic cellular automata

Traffic jam dynamics in stochastic cellular automata

Date: September 1, 1995
Creator: Nagel, K. & Schreckenberg, M.
Description: Simple models for particles hopping on a grid (cellular automata) are used to simulate (single lane) traffic flow. Despite their simplicity, these models are astonishingly realistic in reproducing start-stop-waves and realistic fundamental diagrams. One can use these models to investigate traffic phenomena near maximum flow. A so-called phase transition at average maximum flow is visible in the life-times of jams. The resulting dynamic picture is consistent with recent fluid-dynamical results by Kuehne/Kerner/Konhaeuser, and with Treiterer`s hysteresis description. This places CA models between car-following models and fluid-dynamical models for traffic flow. CA models are tested in projects in Los Alamos (USA) and in NRW (Germany) for large scale microsimulations of network traffic.

Assessment of the energy impacts of improving highway-infrastructure materials

Assessment of the energy impacts of improving highway-infrastructure materials

Date: April 1, 1995
Creator: Stammer, R.E. Jr. & Stodolsky, F.
Description: Argonne National Laboratory has conducted a study to ascertain the relative importance of improved highway materials compared to vehicle energy consumption on US energy consumption. Energy savings through an improved highway infrastructure can occur in at least three ways. First, replacing aged and failing materials with improved and advanced materials can produce energy ``use`` savings. Second, advances in materials science can yield energy efficiency gains in the production of infrastructure materials. Third, using new or improved transportation-infrastructure materials that have longer service life reduces the energy expended in producing replacement materials and installing or repairing facilities. The Argonne study finds that energy savings from highway materials improvements are on the order of 0.1 {times} 10{sup 12} to 2.1 {times} 10{sup 12} Btu. This savings is relatively small compared with energy savings from improvements in vehicle fuel economy. Several infrastructure improvement scenarios were examined, with results that were highly dependent on the assumptions. Reducing traffic congestion, particularly in high-traffic-volume locations, produces major energy savings compared with the other scenarios.

Description: Mound, located in Montgomery County, Miamisburg, Ohio, on the east bank of the Great Miami River, was established in 1948 by the Atomic Energy Commission to develop and manufacture explosive devices for the United States Government. Mound occupies 305 acres and at present the facility is operated by EG&G Mound Applied Technologies. It is devoted to research, development, testing and manufacturing of components for nuclear weapons systems under the auspices of the United States Department of Energy (DOE). The complex employs approximately 2,200 people generating an annual payroll in excess of $75 million. Whereas Government sponsors have traditionally placed great emphasis on new technological concepts and manufacturing processes for weapons, unfortunately, such has not been the case in the maintenance of the roadway infrastructure. The roadway system which, for the most part is 40 years old, must be restored to a condition which will ensure smooth transportation of weapon component production, safe access for emergency and fire vehicles and safe ingress and egress for pedestrian personnel. This Facilities Capability Assurance Program (FCAP) project will provide this much needed restoration.

1995 Bird survey Foothills parkway section 8B National Park Service, Tennessee

Date: May 1, 1996
Creator: Wade, M.C.; Giffen, N.R. & Wade, B.A.
Description: The Foothills Parkway Section 8B right-of-way (ROW) is a stretch of land between Pittman Center and Cosby, Tennessee that is approximately 14.2 miles long and 1,000 ft wide, with a considerably wider section on Webb Mountain. A breeding bird survey was conducted at selected sample points along the ROW. The intent of the survey was to identify bird communities, area sensitive species (birds dependent on extensive forest systems for all their needs) and endangered, threatened, federal candidate, and state `in need of management` species now using the ROW. The survey also provides baseline data to assess future habitat impacts as well as cumulative impacts of the project.
