Hybrid simulations of quasineutral phenomena in magnetized plasma

Description: A new class of numerical algorithms for computer simulation of low frequency electromagnetic and electrostatic phenomena in magnetized plasma is presented. Maxwell's equations are solved in the limits of quasineutrality and negligible transverse displacement current (Darwin's model). Electrons are modeled as a fluid with polarization effects ignored. Ions are described as particles. A novel feature of these algorithms is the use of the electron fluid equation of motion to determine the electric… more

Research on the physical properties of geothermal reservoir rock. Annual report, September 1, 1977

Description: Measurements have been made of the electrical resistivity, the acoustic wave speed, density, and water content of six groups of rock samples taken from Cenozoic volcanic units. It has been found from these measurements that the correlations between physical properties are significantly different in the case of volcanic rocks than in the case of sandstones and limestones. For a given porosity and water content, the resistivity of a volcanic rock is several fold greater than that of a sandstone o… more

Summary of ORNL investigation of in-core vibrations in BWR-4s

Description: This report describes the use of noise analysis to investigate in-core instrument tube vibrations in BWR-4 reactors. Neutron noise signals from in-core fission chambers and acoustic noise signals from externally mounted accelerometers were used in these studies. The results show that neutron noise can be used to detect vibration and, more importantly, impacting of instrument tubes against adjacent fuel channel boxes. Externally mounted accelerometers detect impacting but not rubbing of instrume… more

Geophysical and geochemical models of the Earth's shields and rift zones

Description: This report summarizes a collection of, synthesis of, and speculation on the geophysical and geochemical models of the earth's stable shields and rift zones. Two basic crustal types, continental and oceanic, and two basic mantle types, stable and unstable, are described. It is pointed out that both the crust and upper mantle play a strongly interactive role with surface geological phenomena ranging from the occurrence of mountains, ocean trenches, oceanic and continental rifts to geographic dis… more

Tank study committee report

Description: Six major problem areas have surfaced in the past twenty-five years concerning the use of plutonium tankage. The most significant of these involves the use of borosilicate glass as a neutron absorber. Approximately thirty recommendations and criteria resulted from a study of these problem areas. Not all of the criteria and recommendations are unanimously supported by all members of the committee. The committee agrees that problem areas that can be handled on a short-term basis are being pursued… more

Blistering effects in neutral injection systems operated with helium and hydrogen gases: a preliminary assessment

Description: The practical effects of blistering and flaking in neutral injection systems are studied. These effects will soon be more important because of energy increases in systems now under development and because of their operation with fast helium ions as well as hydrogen and deuterium ions. Two main effects were studied: enhanced erosion rate and possible voltage breakdown from sharp flakes and gas emission.

Design, operation, and initial results from capsule OC-1, the first of a series of graphite creep irradiation experiments. [HTGR]

Description: A series of 12 irradiation experiments was designed to evaluate the creep characteristics of graphites when exposed to elevated temperatures and high fast fluences. Various graphites of interest to HTGR designers are to be examined. The series encompasses the irradiation of 28 specimens, each 15.24 mm (0.6 in.) in diameter by 25.4 mm (1 in.) long, to incremental exposures of 1, 2, 4, and 8 E + 25 n/m/sup 2/ (E greater than 0.18 MeV) at 900/sup 0/C; 28 similar specimens to the same exposures at … more

Geologic characteristics of a portion of the Salton Sea geothermal field

Description: The examination of drill cuttings and core samples from the Magmamax Nos. 2 and 3 and Woolsey No. 1 wells indicate that the sequence of sedimentary rocks in the Salton Sea geothermal field from the surface to below 4000 ft can be divided into three categories: cap rock, unaltered reservoir rocks, and hydrothermally altered reservoir rocks. The cap rock extends from the surface to a depth of approximately 1100 ft in all three wells. There is evidence to suggest that the cap rock has undergone se… more

Chattanooga shale: uranium recovery by in situ processing

Description: The increasing demand for uranium as reactor fuel requires the addition of sizable new domestic reserves. One of the largest potential sources of low-grade uranium ore is the Chattanooga shale--a formation in Tennessee and neighboring states that has not been mined conventionally because it is expensive and environmentally disadvantageous to do so. An in situ process, on the other hand, might be used to extract uranium from this formation without the attendant problems of conventional mining. W… more

Flooding and mass transfer in Goodloe-packed columns, Part 2. [HTGR]

Description: Krypton gas is recovered from HTGR off-gas streams by countercurrent absorption in liquid carbon dioxide. Goodloe stainless steel wire mesh packing was chosen for the absorption columns since the process operates at -20/sup 0/C and about 20 atm pressure. Flooding points and an overall mass transfer coefficient for Goodloe-packed columns were determined with a carbon dioxide-air-water system for 6.4 and 15.2-cm-ID columns. Flood points were obtained for liquid-to-gas mass velocity ratios of 20 t… more

Compressible fluid flow through rocks of variable permeability

Description: The effectiveness of course-grained igneous rocks as shelters for burying radioactive waste can be assessed by determining the rock permeabilities at their in situ pressures and stresses. Analytical and numerical methods were used to solve differential equations of one-dimensional fluid flow through rocks with permeabilities from 10/sup 4/ to 1 nD. In these calculations, upstream and downstream reservoir volumes of 5, 50, and 500 cm/sup 3/ were used. The optimal size combinations of the two res… more
