Estimate of earth media shear strength at the Nevada Test Site

Description: A method is presented of estimating the effective shear strength of the fractured rock that surrounds a nuclear detonation. To do this, we measure the cavity radii from previous detonations. We also use numerical computer codes to model the explosion phenomenology and develop the functional relationship between the normalized cavity displacement and the normalized shear strength of the rock. In this sense, the computer codes serve as replica models that are dimensionally analyzed to interpret t… more

Age changes in human bone: an overview

Description: The human skeleton steadily changes structure and mass during life because of a variety of internal and external factors. Extracellular substance and bone cells get old, characteristic structural remodeling occurs with age and these age-related changes are important in the discrimination between pathological and physiological changes. Perhaps 20 percent of the bone mass is lost between the fourth and the ninth decades, osteoblasts function less efficiently and gradual loss of bone substance is … more

Interim report on the creepdown of Zircaloy fuel cladding

Description: This report describes the creepdown phenomenon in Zircaloy fuel cladding and the methods by which it will be measured and analyzed. Instrumentation for monitoring radial deformation in the cladding is described in detail--in terms of theory, design, and stability. The programs that control the microcomputer are listed, both to document the level of sophistication of the instrumentation and to indicate the flexibility of the test equipment.

Tandem mirror rate code and cyclic purging of alphas in tandem reactors

Description: A set of coupled rate equations for densities and energies in a tandem mirror machine have been incorporated into a fast-running code. The code is suitable for parameter-searching and studying time-dependent processes. The code has been used to study buildup of thermalized alphas in a tandem mirror reactor, and cyclic schemes for limiting the alpha population. The principal findings are: Q/sub av/ is drastically reduced as alphas build up from a steady-state in which alphas were artificially el… more

Mark I 1/5-sale boiling water reactor pressure suppression experiment quick-look report

Description: This report is intended as a ''quick-look'' report summarizing the experimental results obtained from pressure suppression experiment numbers 1.3.1, 1.4, 1.5, and 1.6 that were performed on the Lawrence Livermore Laboratory's 1/5-scale boiling water reactor (BWR) Mark I pressure suppression experimental facility on April 26, 1977. A brief description of the general nature of the tests and a summary of the actual tests that were performed are given.

Electrostatic bounce modes in mirror plasmas

Description: Electrostatic bounce modes are standing waves that occur in a mirror plasma when the relative spread in electron bounce frequencies is small. The modes can be destabilized by an ion distribution with a peaked perpendicular energy, and experimental data suggest that this mechanism was the principal cause of instability in certain low-density mirror experiments. After a review of theoretical work on electrostatic waves in mirror plasmas, a general matrix eigenvalue equation for the wave potential… more

Summary progress report for fiscal year 1976 and the transition quarter describing technical assistance work for the Division of Systems Safety, U. S. Nuclear Regulatory Commission. [HTGR]

Description: The report reviews briefly the HTGR core analytical methods that were developed during the course of the program. The features of these analytical methods are compared with methods used to perform similar analyses, and examples of the use of these methods are cited. Included are discussions of HEATUP (a computer code for the thermal analysis of an LOFC accident in an HTGR), HEATING 5 (an IBM 360 heat-conduction code), CCCM (a coupled conduction-convection model for core thermal analysis), FLODI… more

Environmental assessment report: joint ERDA/GPE massive hydraulic fracturing experiment, Natural Buttes Unit, Uintah Co. , Utah

Description: This environmental assessment was prepared as a negative declaration regarding the environmental impacts associated with the joint Gas Producing Enterprises (GPE) and ERDA project to stimulate six natural gas wells by massive hydraulic fracturing in the Uinta Basin of Utah. The results of this program could prove valuable in the exploitation of those potentially recoverable gas reserves in low permeability reservoirs as identified in the National Gas Survey by the Federal Power Commission.

Measurement of energy deposited by charged particle beams in composite targets. [0. 5 to 28. 5 GeV]

Description: The energies deposited in composite targets by proton beams from 0.8 to 28.5 GeV energy and by an electron beam at 0.5 GeV energy were measured. The targets consisted of various thicknesses of /sup 238/U shower plates backed by a composite detector plate consisting of a 5-cm-thick CH/sub 2/ moderator and a 0.635-cm /sup 238/U plate. The spacing between the shower and detector plates was varied to allow different spreading of the shower between plates. Passive detectors (thermoluminescence dosim… more

Interim report on performance tests of a total flow impulse turbine for geothermal applications

Description: A new two-phase expander was successfully tested in the laboratory. An engine efficiency of 23 percent for a single-nozzle test was measured. Performance predictions of a numerical model agree well with experimental results. Full admission performance, based upon the numerical model and achievable nozzle thrust coefficients indicate that full admission engine efficiency between 38 and 48 percent can be realized with present technology. Droplet size reduction and enhanced two-phase flow analysis… more

Experimental investigation of retrofit options for mobile homes

Description: A mobile home located (outdoors) in Oak Ridge, Tennessee, was tested to determine its energy-use characteristics for both space heating and cooling. The main objective was to determine the energy savings that can be achieved by the addition of retrofit items such as storm windows, skirting, and extra insulation and how these savings vary with weather conditions. Analyses of space heating data show that energy savings approaching 50 percent can be achieved, but analyses of space cooling data wer… more

Proposed apparatus for measuring internal friction in rocks at high temperatures and pressures: a design analysis

Description: An apparatus is described that measures internal friction in rocks at high temperatures (approximately 800/sup 0/C) and pressures (approximately 1.0 GPa). Steady oscillations (approximately 1.0 Hz) are induced in a jacketed sample while coaxial capacitive transducers monitor the resulting radial strain. Sample strains are continuously compared to the deformation of a low-loss standard, which acts as a stress transducer. The stress state produced is uniaxial stress. We use the theory of viscoela… more
