Acidification of geothermal wells: Laboratory experiments. Geothermal Reservoir Well-Stimulation program

Description: The laboratory testing of the reactions of acetic, formic, hydrochloric, and hydrofluoric acids with calcium carbonate, kaolin, sepiolite, and two formation materials at geothermal temperatures is described. A workable test procedure was developed which provided information regarding the relative reactivities of selected minerals or formation materials with three of the four acids investigated. Tests with hydrochloric acid were complicated by reactions of the acid with the test vessel materials… more

Acoustic agglomeration of power plant fly ash. Final report

Description: The work has shown that acoustic agglomeration at practical acoustic intensities and frequencies is technically and most likely economically viable. The following studies were performed with the listed results: The physics of acoustic agglomeration is complex particularly at the needed high acoustic intensities in the range of 150 to 160 dB and frequencies in the 2500 Hz range. The analytical model which we developed, although not including nonlinear acoustic efforts, agreed with the trends obs… more

Acoustic disturbance at ionospheric heights caused by the MILL RACE explosion

Description: The principal objective of the Los Alamos National Laboratory in the MILL RACE experiment was to measure the over-head ionospheric response due to the MILL RACE explosion. Such a measurement enables one to test computer models designed to quantitatively predict ionospheric disturbances caused by known sources. The emphasis of the models has been directed at calculating effects on rf propagation associated with the predicted ionospheric disturbances. Consequently vertical incidence phase soundin… more

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

An Adaptive Finite Difference Method for Hyperbolic Systems in OneSpace Dimension

Description: Many problems of physical interest have solutions which are generally quite smooth in a large portion of the region of interest, but have local phenomena such as shocks, discontinuities or large gradients which require much more accurate approximations or finer grids for reasonable accuracy. Examples are atmospheric fronts, ocean currents, and geological discontinuities. In this thesis we develop and partially analyze an adaptive finite difference mesh refinement algorithm for the initial bound… more

Adaptive Mesh Refinement for 1-Dimensional Gas Dynamics

Description: We consider the solution of the one-dimensional equation of gas-dynamics. Accurate numerical solutions are difficult to obtain on a given spatial mesh because of the existence of physical regions where components of the exact solution are either discontinuous or have large gradient changes. Numerical methods treat these phenomena in a variety of ways. In this paper, the method of adaptive mesh refinement is used. A thorough description of this method for general hyperbolic systems is given else… more

Additional Pu-238 production

Description: Possible DOD demands for up to 1 MW thermal of heat sources could be partially met by increasing SRP Pu-238 production. The Pu-238 would be an alternate or supplement to Sr-90 in these heat sources. There is a growing surplus of Np-237 target material which could be used to produce high-assay Pu-238 (83.5%). In addition SRP produces low assay Pu-238 (approx. 27%) that could be extracted instead of being sent to the waste tanks. About 216 kg or 121 kw thermal of additional high-assay Pu-238 coul… more

Adiabatic compression of elongated field-reversed configurations

Description: The simplest model of plasma dynamics is the adiabatic model. In this model the plasma is assumed to be in MHD equilibrium at each instant of time. The equilibria are connected by the requirement that they all have the same entropy per unit flux, i.e., the equilibria form a sequence generated by adiabatic changes. The standard way of computing such a sequence of equilibria was developed by Grad, but its practical use requires a fairly complicated code. It would be helpful if approximately the s… more

Adiabatic invariants for field-reversed configurations

Description: Field reversed configurations (FRCs) are characterized by azimuthal symmetry, so two exact constants of the particle motion are the total particle energy E and the canonical angular momentum P/sub theta/. For many purposes it is desirable to construct a third (diabatic) constant of the motion if this is possible. It is shown that for parameters characteristic of current FRCs that the magnetic moment ..mu.. is a poor adiabatic invariant, while the radial action J is conserved rather well.

Adsorption of organics from tar sand water by activated carbon in packed beds. Final report

Description: The adsorption of TS-1S and TS-2C tar sand waters were studied at 278 and 298/sup 0/K on activated carbon in both batch and packed bed experiments. The isotherms were nonlinear over the entire liquid concentration ranges. Breakthrough curves were obtained in packed bed experiments as a function of bed lengths, particle size, and liquid velocity. A mechanistic approach was used to solve the mass transfer equations for the packed adsorber, the mass transfer coefficients and the rates of adsorptio… more

Advanced design of positive-ion sources for neutral-beam applications

Description: The APIS ion source is being developed to meet a goal of producing ion beams of less than or equal to 200 keV, 100 A, with 10-30-s pulse lengths. In a continuing effort to advance the state of the art and to produce long pulse ion beams, APIS ion sources with grid dimensions of 10 x 25 cm, 13 x 43 cm, and 16 x 48 cm are being developed. In the past year, the 10- x 25-cm ion source has been operated to produce ion beams in excess of 100 keV for many seconds pulse length. An advanced design conce… more

Advanced gas-cooled nuclear reactor materials evaluation and development program: corrosion behavior of experimental alloys in controlled-purity helium at temperatures in the 750 to 1050/sup 0/C range. [Ni-20Cr + Al, Ti, Si, Nb and/or Y]

Description: A series of 10 experimental alloys (basically Ni-20Cr with addition of one or more of the elements Al, Ti, Si, Nb and Y) has been examined after exposure to controlled purity helium for periods of 1000 to 6000 hours at temperatures of 750 to 1050/sup 0/C. Alloys containing aluminum were particularly susceptible to internal oxidation at the lower temperatures, but at 950/sup 0/C and above carburization became the dominant corrosive mechanism. The most corrosive resistant alloys were Ni-Cr20 and … more
