Groundwater maps of the Hanford Site, December 1993 (open access)

Groundwater maps of the Hanford Site, December 1993

This report is an update to the series of reports that document the configuration of the uppermost unconfined aquifer beneath the Hanford Site. This series presents the latest results of the semiannual water level measurement program and the water table maps generated from these measurements. The reports document the changes in the groundwater level at the Hanford Site during the transition from nuclear material production to environmental restoration and remediation. In addition, these reports provide water level data to support the various site characterization and groundwater monitoring programs currently in progress on the Hanford Site. The three major operations areas (the 100, 200 and 300/1100 Areas) where wastes were discharged to the soil are covered in this update. The water level measurements from the wells in these areas are portrayed on a set of maps to illustrate the hydrologic conditions and are also tabulated in an appendix. A summary discussion of the data is included with the well index map, the depth to water map, and the contoured map of the water table surface for each of the three areas.

The effect of frequency on Young`s modulus and seismic wave attenuation (open access)

The effect of frequency on Young`s modulus and seismic wave attenuation

Laboratory experiments were performed to measure the effect of frequency, water-saturation, and strain amplitude on Young`s modulus and seismic wave attenuation on rock cores recovered on or near the site of a potential nuclear waste repository at Yucca Mountain, Nevada. The purpose of this investigation is to perform the measurements using four techniques: cyclic loading, waveform inversion, resonant bar, and ultrasonic velocity. The measurements ranged in frequency between 10{sup {minus}2} and 10{sup 6} Hz. For the dry specimens Young`s modulus and attenuation were independent of frequency; that is, all four techniques yielded nearly the same values for modulus and attenuation. For saturated specimens, a frequency dependence for both Young`s modulus and attenuation was observed. In general, saturation reduced Young`s modulus and increased seismic wave attenuation. The effect of strain amplitude on Young`s modulus and attenuation was measured using the cyclic loading technique at a frequency of 10{sup {minus}1} Hz. The effect of strain amplitude in all cases was small. For some rocks, such as the potential repository horizon of the Topopah Spring Member tuff (TSw2), the effect of strain amplitude on both attenuation and modulus was minimal.

Advanced human-system interface design review guideline. General evaluation model, technical development, and guideline description (open access)

Advanced human-system interface design review guideline. General evaluation model, technical development, and guideline description

Advanced control rooms will use advanced human-system interface (HSI) technologies that may have significant implications for plant safety in that they will affect the operator`s overall role in the system, the method of information presentation, and the ways in which operators interact with the system. The U.S. Nuclear Regulatory Commission (NRC) reviews the HSI aspects of control rooms to ensure that they are designed to good human factors engineering principles and that operator performance and reliability are appropriately supported to protect public health and safety. The principal guidance available to the NRC, however, was developed more than ten years ago, well before these technological changes. Accordingly, the human factors guidance needs to be updated to serve as the basis for NRC review of these advanced designs. The purpose of this project was to develop a general approach to advanced HSI review and the human factors guidelines to support NRC safety reviews of advanced systems. This two-volume report provides the results of the project. Volume I describes the development of the Advanced HSI Design Review Guideline (DRG) including (1) its theoretical and technical foundation, (2) a general model for the review of advanced HSIs, (3) guideline development in both hard-copy and …

Piping benchmark problems for the ABB/CE System 80+ Standardized Plant (open access)

Piping benchmark problems for the ABB/CE System 80+ Standardized Plant

To satisfy the need for verification of the computer programs and modeling techniques that will be used to perform the final piping analyses for the ABB/Combustion Engineering System 80+ Standardized Plant, three benchmark problems were developed. The problems are representative piping systems subjected to representative dynamic loads with solutions developed using the methods being proposed for analysis for the System 80+ standard design. It will be required that the combined license licensees demonstrate that their solution to these problems are in agreement with the benchmark problem set. The first System 80+ piping benchmark is a uniform support motion response spectrum solution for one section of the feedwater piping subjected to safe shutdown seismic loads. The second System 80+ piping benchmark is a time history solution for the feedwater piping subjected to the transient loading induced by a water hammer. The third System 80+ piping benchmark is a time history solution of the pressurizer surge line subjected to the accelerations induced by a main steam line pipe break. The System 80+ reactor is an advanced PWR type.

Carbon taxes and India (open access)

Carbon taxes and India

Using the Indian module of the Second Generation Model 9SGM, we explore a reference case and three scenarios in which greenhouse gas emissions were controlled. Two alternative policy instruments (carbon taxes and tradable permits) were analyzed to determine comparative costs of stabilizing emissions at (1) 1990 levels (the 1 X case), (2) two times the 1990 levels (the 2X case), and (3) three times the 1990 levels (the 3X case). The analysis takes into account India`s rapidly growing population and the abundance of coal and biomass relative to other fuels. We also explore the impacts of a global tradable permits market to stabilize global carbon emissions on the Indian economy under the following two emissions allowance allocation methods: (1) {open_quotes}Grandfathered emissions{close_quotes}: emissions allowances are allocated based on 1990 emissions. (2) {open_quotes}Equal per capita emissions{close_quotes}: emissions allowances are allocated based on share of global population. Tradable permits represent a lower cost method to stabilize Indian emissions than carbon taxes, i.e., global action would benefit India more than independent actions.

Macromolecular structure analysis and effective liquefaction pretreatment. Final report (open access)

Macromolecular structure analysis and effective liquefaction pretreatment. Final report

This project was concerned with characterizing the changes in coal macromolecular structure, that are of significance for liquefaction pretreatments of coal. The macromolecular structure of the insoluble portion of coal is difficult to characterize. Techniques that do so indirectly (based upon, for example, NMR and FTIR characterizations of atomic linkages) are not particularly sensitive for this purpose. Techniques that characterize the elastic structure (such as solvent swelling) are much more sensitive to subtle changes in the network structure. It is for this reason that we focused upon these techniques. The overall objective involved identifying pretreatments that reduce the crosslinking (physical or chemical) of the network structure, and thus lead to materials that can be handled to a greater extent by traditional liquid-phase processing techniques. These techniques tend to be inherently more efficient at producing desirable products. This report is divided into seven chapters. Chapter II summarizes the main experimental approaches used throughout the project, and summarizes the main findings on the Argonne Premium coal samples. Chapter III considers synergistic effects of solvent pairs. It is divided into two subsections. The first is concerned with mixtures of CS{sub 2} with electron donor solvents. The second subsection is concerned with aromatic hydrocarbon …

Estimating Fuel Cycle Externalities: Analytical Methods and Issues, Report 2 (open access)

Estimating Fuel Cycle Externalities: Analytical Methods and Issues, Report 2

The activities that produce electric power typically range from extracting and transporting a fuel, to its conversion into electric power, and finally to the disposition of residual by-products. This chain of activities is called a fuel cycle. A fuel cycle has emissions and other effects that result in unintended consequences. When these consequences affect third parties (i.e., those other than the producers and consumers of the fuel-cycle activity) in a way that is not reflected in the price of electricity, they are termed ''hidden'' social costs or externalities. They are the economic value of environmental, health and any other impacts, that the price of electricity does not reflect. How do you estimate the externalities of fuel cycles? Our previous report describes a methodological framework for doing so--called the damage function approach. This approach consists of five steps: (1) characterize the most important fuel cycle activities and their discharges, where importance is based on the expected magnitude of their externalities, (2) estimate the changes in pollutant concentrations or other effects of those activities, by modeling the dispersion and transformation of each pollutant, (3) calculate the impacts on ecosystems, human health, and any other resources of value (such as man-made structures), (4) …

Projection Gas Immersion Laser Doping (P-GILD): A resistless, nanosecond thermal doping/diffusion technology (open access)

Projection Gas Immersion Laser Doping (P-GILD): A resistless, nanosecond thermal doping/diffusion technology

Projection Gas Immersion Laser Doping (P-GILD) is an innovative doping process that utilizes finely patterned excimer laser light to thermally process discreet regions within an integrated circuit. By reducing the total temperature cycle to nanoseconds and localizing the thermal energy in depth and area, P-GILD fundamentally changes the junction formation process. This paper first reviews the general characteristics of the P-GILD process and equipment. Two variations of the technique, melt and non-melt, and their resulting junction characteristics are then described in detail. The combination of the two laser processes along with the simplification that a resistless technology brings to the process sequence, enables efficient fabrication of impurity profiles that are ideal for a wide array of transistor applications.

Assessment of CO{sub 2} projections (open access)

Assessment of CO{sub 2} projections

Various projections of the relation between future CO{sub 2} concentrations and future emissions were undertaken as part of the scientific assessment for Working Group 1 of the Intergovernmental Panel on Climate Change. There were three type of calculation: (1) forward projections, calculating the atmospheric CO{sub 2} concentrations resulting from specified emission scenarios, (2) inverse calculations determining the emission rates that would be required to achieve stabilization of CO{sub 2} concentrations via specified pathways and (3) impulse response function calculations required for determining Global Warming Potentials. The use of a standardized set of conditions allows an intercomparison of models. The ocean models used in the calculations presented here span a range of forms from response function descriptions to general circulation models. The general issue for all levels of modelling is whether the model parameters can reasonably be regarded as being the same in the future as at present. Sensitivity studies explore other aspects of the uncertainties of such projections. This report documents the specifications, the models that were used and the results that were obtained. Some preliminary interpretations of the results are included.

Environmental surveillance at Los Alamos during 1992 (open access)

Environmental surveillance at Los Alamos during 1992

This report describes the environmental surveillance program at Los Alamos National Laboratory during 1992. The Laboratory routinely monitors for radiation and for radioactive and nonradioactive materials at (or on) Laboratory sites as well as in the surrounding region. LANL uses the monitoring results to determine compliance with appropriate standards and to identify potentially undesirable trends. Data were collected in 1992 to assess external penetrating radiation; quantities of airborne emissions and liquid effluents; concentrations of chemicals and radionuclides in ambient air, surface waters and groundwaters, municipal water supply, soils and sediments, and foodstuffs; and environmental compliance. Using comparisons with standards, regulations, and background levels, this report concludes that environmental effects from Laboratory operations are small and do not pose a demonstrable threat to the public, laboratory employees, or the environment.

P-wave signatures and parameterization of transversely isotropic media: An overview (open access)

P-wave signatures and parameterization of transversely isotropic media: An overview

Progress in seismic inversion and processing in anisotropic media depends on our ability to relate different seismic signatures to the anisotropic parameters. While the conventional notation (stiffness coefficients) is suitable for forward modeling, it is inconvenient in developing analytic insight into the influence of anisotropy on wave propagation. The author gives a consistent description of P-wave signatures in transversely isotropic media with arbitrary strength of the anisotropy, using the notation suggested by Thomsen (1986). The influence of transverse isotropy on P-wave propagation is shown to be practically independent of the vertical S-wave velocity V{sub S0}, even in models with strong velocity variations. Therefore, the contribution of transverse isotropy to P-wave kinematic and dynamic signatures is controlled by just two anisotropic parameters, {epsilon} and {delta}, with the vertical velocity V{sub P0} being no more than a scaling coefficient in homogeneous models.

Development of analytical and numerical models for the assessment and interpretation of hydrogeological field tests (open access)

Development of analytical and numerical models for the assessment and interpretation of hydrogeological field tests

Mathematical models of the flow and tracer tests in fractured aquifers are being developed for the further study of radioactive wastes migration in round water at the Lake Area, which is associated with one of the waste disposal site in Russia. The choice of testing methods, tracer types (chemical or thermal) and the appropriate models are determined by the nature of the ongoing ground-water pollution processes and the hydrogeological features of the site under consideration. Special importance is attached to the increased density of wastes as well as to the possible redistribution of solutes both in the liquid phase and in the absorbed state (largely, on fracture surfaces). This allows for studying physical-and-chemical (hydrogeochemical) interaction parameters which are hard to obtain (considering a fractured structure of the rock mass) in laboratory. Moreover, a theoretical substantiation is being given to the field methods of studying the properties of a fractured stratum aimed at the further construction of the drainage system or the subsurface flow barrier (cutoff wall), as well as the monitoring system that will evaluate the reliability of these ground-water protection measures. The proposed mathematical models are based on a tight combination of analytical and numerical methods, the former being …

Low-temperature geothermal water in Utah: A compilation of data for thermal wells and springs through 1993 (open access)

Low-temperature geothermal water in Utah: A compilation of data for thermal wells and springs through 1993

The Geothermal Division of DOE initiated the Low-Temperature Geothermal Resources and Technology Transfer Program, following a special appropriation by Congress in 1991, to encourage wider use of lower-temperature geothermal resources through direct-use, geothermal heat-pump, and binary-cycle power conversion technologies. The Oregon Institute of Technology (OIT), the University of Utah Research Institute (UURI), and the Idaho Water Resources Research Institute organized the federally-funded program and enlisted the help of ten western states to carry out phase one. This first phase involves updating the inventory of thermal wells and springs with the help of the participating state agencies. The state resource teams inventory thermal wells and springs, and compile relevant information on each sources. OIT and UURI cooperatively administer the program. OIT provides overall contract management while UURI provides technical direction to the state teams. Phase one of the program focuses on replacing part of GEOTHERM by building a new database of low- and moderate-temperature geothermal systems for use on personal computers. For Utah, this involved (1) identifying sources of geothermal date, (2) designing a database structure, (3) entering the new date; (4) checking for errors, inconsistencies, and duplicate records; (5) organizing the data into reporting formats; and (6) generating a map …
