Accurate monotonicity-preserving cubic interpolation

Description: A simple and effective algorithm to construct a monotonicity-preserving cubic Hermite interpolant for data with rapid variations is presented. Constraining the derivatives of the interpolant according to geometric considerations makes the interpolant consistent with local monotonicity properties of the data. Numerical examples are given that compare the quality and accuracy of the proposed interpolation method with other standard interpolants.

Acoustic-emission monitoring of LOFT fuel-cladding-burst tests

Description: Experiments at the Loss-of-Fluid Test Facility (LOFT), beginning with experiment L6-8 (Anticipated Transient Experiment), will use a core equipped with several pressurized fuel rods. Because some of the tests may produce temperature and pressure conditions which could conceivably burst a number of rods, a nondestructive method for burst detection is needed. Acoustic emission monitoring of a number of tests of small zircaloy tubing samples, each with internal gas volume similar to that of an act… more

Aeroelastic stability analysis of a Darrieus wind turbine

Description: An aeroelastic stability analysis has been developed for predicting flutter instabilities on vertical axis wind turbines. The analytical model and mathematical formulation of the problem are described as well as the physical mechanism that creates flutter in Darrieus turbines. Theoretical results are compared with measured experimental data from flutter tests of the Sandia 2 Meter turbine. Based on this comparison, the analysis appears to be an adequate design evaluation tool.

Agricultural implications of reduced water supplies in the Green and Upper Yellowstone River Basins

Description: The growth of the energy sector in the energy-rich but water-restricted Western US has presented a potential conflict with the irrigated agricultural sector. This study measures the direct impacts on farm income and employment resulting from the transfer of water from agriculture to energy in two specific geographical areas - the Green and Upper Yellowstone River Basins. We used a linear programming model to evaluate the impacts of reduced water supplies. Through the use of regional multipliers… more

Los Alamos plutonium facility applied systems integration project status report for period ending August 31, 1981

Description: The conceptual design of an on-line, near-real-time nondestructive assay instrumentation network for the Los Alamos Plutonium Facility is complete. Analysis of instrument history data indicates that the instrument certification procedures need improvement. Analysis of exhaust filter data has led to the derivation of a buildup prediction equation that is a function of throughput. This suggests that development of a generalized model is possible. A number of routine reports are now available from… more

Analysis of large-leak test SWAT-3 Run-6 data by use of sodium-water-reaction analysis code SWAAM-I

Description: The Sodium Water Advanced Analysis Method computer code (SWAAM-I) is used to analyze the large-leak test data SWAT-3 Run-6. The SWAT-3 is the mockup of the secondary system of the Japanese breeder-reactor demonstration plant Monju. The steam-generator design for the Monju reactor was a helical-coil-tube type with a cover-gas space, and the SWAT-3 Run-6 Test vessel simulates this design of the steam generator. The objectives of this work are: (1) to examine the adequacy of the SWAAM-I code for t… more

Analysis of magma-thermal conversion of biomass to gaseous fuel

Description: A wide range of magma types and pluton geometries believed to occur within the upper 10 km of the crust provide suitable sources of thermal energy for conversion of water-biomass mixtures to higher quality gaseous fuel. Gaseous fuel can be generated within a magma body, within the hot subsolidus margins of a magma body, or within surface reaction vessels heated by thermal energy derived from a magma body. The composition, amount, and energy content of the fuel gases generated from water-biomass… more

Analysis of Mirnov oscillations on PDX

Description: Mirnov coils have been used to study MHD oscillations in PDX. We first review the information that can be obtained from Mirnov coils concerning the amplitude of these oscillations and their toroidal and poloidal mode numbers. The usual techniques for analyzing Mirnov coil data do not work well on PDX because of the rectangular arrangement of the coils, substantial noise levels, and poloidal amplitude asymmetries. A technique using digital Fourier analysis to focus attention on the fundamental f… more

Analysis of the cost of mined geologic repositories in alternative media

Description: IN 1981, the Pacific Northwest Laboratory (PNL) conducted an analysis of the costs of using salt, granite, basalt or tuff to isolate spent nuclear fuel. Preliminary cost estimates were made and the conditions affecting cost in each medium were examined parametrically. The analysis was conducted using a repository cost model named RECON, created for this project. Data for the model were gathered from recent conceptual design studies completed and under way, from the Generic Environmental Impact … more

Analysis of the role of an interfacility SNM accounting system

Description: Lawrence Livermore National Laboratory (LLNL) undertook the task of analyzing the actual and potential value of an interfacility NRC material accounting system in deterring and detecting both material diversion and facility material accounting data falsification. The most important conclusion is that only relatively minor changes are needed to upgrade the current NRC interfacility reporting system. The emphasis of the task was on evaluating the usefulness of an NRC-monitored material accounting… more

Analysis of x-ray production in TMX upgrade

Description: TMX Upgrade (TMX-U), a tandem mirror experiment at LLNL, will use high power microwaves for electron cyclotron resonant heating (ECRH). As demonstrated on Elmo Bumpy Torus (EBT) and related experiments which use similar heating techniques, high energy electron populations are created. In these devices, which run CW, significant x-ray production occurs and adequate shielding must be provided for personnel protection. TMX-U is a pulsed experiment; however, significant x-ray production is expected… more

Antiproton physics in the next decade

Description: Notes from a talk at the LAMPF II workshop are given. Topics include antinucleon physics in the next decade - the role of anti p and anti n beams in shedding light on some fundamental problems in nuclear and particle physics. Some particle aspects considered include; a) anti n as a source of antiquarks (anti NN provides a well-suited entrance channel for formation of new kind of mesons), and b) possibility of forming quark-gluon phase in anti N annihilations in nuclei. Some nuclear aspects disc… more

The Application of Neutron-Activation Analysis to the Determination of Leach Rates of Simulated Nuclear-Waste Forms

Description: The application of neutron activation analysis to the determination of element release from simulated nuclear waste forms during leaching is described for several different glasses. Potential neutron irradiation effects are discussed, and it is shown, by a series of leach tests on activated and non-activated glass samples, that neutron irradiation has no discernible effect on the release of silicon and cesium during leaching. The radioisotopes best suited for analysis with this method and their… more

Application of the implicit TENSOR code to studies of containment of undergound nuclear tests

Description: The TENSOR code, a two-dimensional finite-difference code, has been used extensively for the solution of stress wave propagation problems in materials, particularly those associated with the containment of underground nuclear test. These problems are typically characterized by shock waves at early times and by nearly incompressible flow at later times. To address this type of problem more economically, an implicit Newmark time integration has been implemented. Implicit differencing requires the… more

Application of US upper wind data in one design of tethered wind energy systems

Description: The upper atmospheric wind resource for the continental United States, Hawaii, and Alaska is assessed. The raw data were obtained from the National Center for Atmospheric Research, Boulder, Colo. The probability distributions of velocity are presented for 54 sites, and detailed calm wind analyses have been undertaken for five of these locations. On the average, the wind lulls about one day per week for a period in excess of about 30 hours. It is shown that the average power density of this wind… more
