Magma Energy Research Project. Project summary, July 1, 1974--June 30, 1975

Description: The objective of the Magma Energy Research Project now under way at Sandia Laboratories is to investigate the feasibility of extracting energy directly from deeply buried circulating magma sources. Project plans describe a concept whereby a fully closed heat exchanger system is inserted directly into such a magma source to allow the heat energy to be brought to the surface with minimal environmental impact. A summary of previous efforts is given. The achievements and future plans for source loc… more

Conceptual design of a regional water quality screening model. [RFF; Reach; HANFORD; ARQUAL; SEAS; NASQUAN]

Description: This water quality assessment methodology is intended to predict concentrations at future times and to estimate the impacts on water quality of energy-related activities (including industrial boilers). Estimates of impacts on water quality at future times are based on incremental changes in pollutant inputs to the body water. Important features of the model are: use of measured concentrations to account for existing conditions; consideration of incremental changes in pollutant loads; emphasis o… more

Measurement uncertainties and minimum detectable concentrations for the in situ NaI gamma spectroscopy systems used at the Fernald site.

Description: This report determines the uncertainties associated with measurements made by using the mobile gamma-ray spectrometers deployed at the U.S. Department of Energy's Fernald Closure Project to characterize soil contaminated with {sup 238}U, {sup 226}Ra, and {sup 232}Th. It also examines minimum detectable concentrations (MDCs) for these instruments. The spectrometers use sodium iodide (NaI) detectors and are mounted on a variety of platforms that allow access to all areas of the site, including de… more

Assessing Potential Impacts Associated With Contamination Events in Water Distribution Systems : A Sensitivity Analysis.

Description: An understanding of the nature of the adverse effects that could be associated with contamination events in water distribution systems is necessary for carrying out vulnerability analyses and designing contamination warning systems. This study examines the adverse effects of contamination events using models for 12 actual water systems that serve populations ranging from about 104 to over 106 persons. The measure of adverse effects that we use is the number of people who are exposed to a contam… more

Tokamak first-wall coating program development

Description: The development of a research program to study coatings for control of impurities originating from the first wall of a Tokamak reactor is extensively discussed. The first wall environment and sputtering, temperature, surface chemical, and bulk radiation damage effects are reviewed. Candidate materials and application techniques are discussed. The philosophy and flow chart of a recommended coating development plan are presented and discussed. Projected impacts of the proposed plan include benefi… more

Effects of atmospheric deposition of energy-related pollutants on water quality: a review and assessment

Description: The effects on surface-water quality of atmospheric pollutants that are generated during energy production are reviewed and evaluated. Atmospheric inputs from such sources to the aquatic environment may include trace elements, organic compounds, radionuclides, and acids. Combustion is the largest energy-related source of trace-element emissions to the atmosphere. This report reviews the nature of these emissions from coal-fired power plants and discusses their terrestrial and aquatic effects fo… more

Hierarchical analysis of molecular spectra

Description: A novel representation of molecular spectra in terms of hierarchical trees has proven to be an important aid for the study of many significant problems in gas-phase chemical dynamics. Trees are generated from molecular spectra by monitoring the changes that occur in a spectrum as resolution is changed in a continuous manner. A tree defines a genealogy among all lines of a spectrum. This allows for a detailed understanding of the assignment of features of a spectrum that may be difficult to obta… more

Material surface modification for first wall protection

Description: The elements and strategy of a program to develop low Z surfaces for tokamak reactors is described. The development of low Z coated limiters is selected as an interim goal. Candidate materials were selected from the elements: Be, B, Al, Ti, V, C, O, N and their compounds. The effect of low energy erosion on surface morphology is shown for Be, TiC and VBe/sub 12/. The tradeoffs in coating design are described. Stress analysis results for TiB/sub 2/ coated POCO graphite limiters for ORNL's ISX-B … more

Water quality issues and energy assessments

Description: This report identifies and evaluates the significant water quality issues related to regional and national energy development. In addition, it recommends improvements in the Office assessment capability. Handbook-style formating, which includes a system of cross-references and prioritization, is designed to help the reader use the material.

Case study: Evaluation of a scenario for the reuse of structures in the production area at Fernald

Description: The potential for the reuse of uncontaminated structures at federal facilities that are being remediated should be evaluated. Although various factors often limit the viability of such reuse, it may be economically attractive to reuse selected structures. Consideration of a hypothetical reuse scenario for the US Department of Energy`s Fernald, Ohio facility shows that the reuse of selected buildings that were not significantly contaminated by production activities at the site may be considerabl… more

Estimating D and D costs for structures at DOE facilities: Some considerations

Description: A number of issues are examined related to estimating decontamination and decommissioning costs for structures at US Department of Energy facilities. The ability to develop detailed estimates for such facilities is generally well established and the general range of costs for such activity is well understood. However, current ability to quickly develop credible planning estimates is more limited. A need exists for a continuing synthesis of experience to allow for an improved ability to develop … more

On-site disposal of decontaminated and dismantled (D and D) materials: A management approach

Description: The Fernald Environmental Management Project (FEMP) is a federal facility located near Cincinnati, Ohio that is being remediated. Operable Unit 3 (OU3) of the FEMP consists of 232 buildings and other structures that formerly housed various uranium and thorium metallurgical and chemical processes. The buildings are constructed primarily of steel and concrete, with transite siding. The structures are being decontaminated and dismantled using an interim remedial action approach. The disposition of… more

Standard review plan on antitrust reviews. Final report

Description: This standard review plan describes the procedures used by NRC staff to implement the antitrust review and enforcement provisions in Sections 105 and 186 of the Atomic Energy Act of 1954, as amended (the Act), and replaces NUREG-0970. These procedures are principally derived from the Commission`s Rules and Regulations in 10 CFR Sections 2.101, 2.102, Part 2-Appendix A, Section X, 50.33a, 50.80, 50.90, and 52.77. These procedures set forth the steps and criteria the staff uses in antitrust revie… more

Energy Randomisation. How Much of Rotational Phase Space Is Explored? How Long Does It Take?

Description: In applying modern theories (RRKM) of unimolecular reaction, it is necessary to decide the volume of phase space in which the energy is assumed to be randomized. The question of whether the K rotational quantum number is conserved impacts on that choice. The conceptual sequence from experimental spectra, through analysis, and interpretation in terms of K relaxation is described for ethanol and 1-butyne in the 3 micron region. The interpretation of molecular eigenstate spectra involves identific… more

Land use and energy

Description: This report provides estimates of the amount of land required by past and future energy development in the United States and examines major federal legislation that regulates the impact of energy facilities on land use. An example of one land use issue associated with energy development - the potential conflict between surface mining and agriculture - is illustrated by describing the actual and projected changes in land use caused by coal mining in western Indiana. Energy activities addressed i… more
