Mathematical Modeling and Evaluation of Radionuclide Transport Parameters from the ANL Laboratory Analog Program

Description: Computer model simulation is required to evaluate the performance of proposed or future high-level radioactive waste geological repositories. However, the accuracy of a model in predicting the real situation depends on how well the values of the transport properties are prescribed as input parameters. Knowledge of transport parameters is therefore essential. We have modeled ANL's Experiment Analog Program which was designed to simulate long-term radwaste migration process by groundwater flowing… more

Burner Stabilized Flames in Fluids

Description: In this report it is shown that a burner placed in a combustible fluid can have a stabilizing effect on a plane flame. A mathematical model is derived in which the flame is modeled as a surface of discontinuity in the flow field. Jump conditions for the fluid variables, as well as an expression for the flame speed, are obtained from an asymptotic analysis of the detailed structure of the flame. The model is applied to investigate the linear stability of a plane flame. Stable behavior is shown t… more

Implementation of Monitors with Macros: A Programming Aid for the HEP and Other Parallel Processors, Revision 1

Description: In this report we give a detailed presentation of how monitors can be implemented on the HEP using a simple macro processor. We then develop the thesis that a small body of general-purpose monitors can be defined to handle most standard synchronization patterns. We include the macro packages required to implement some of the more common synchronization patterns, including the fairly complex logic discussed in a previous paper. Code produced using these macro packages is portable from one multip… more

Radiation doses in granite around emplacement holes in the Spent Fuel Test - Climax. Final report

Description: Final comparisons are made between measured and calculated radiation doses around the holes in which the spent fuel was emplaced in the Spent Fuel Test - Climax. Neutron doses were found to be negligible compared with gamma doses. Good agreement was found between the doses predicted by Monte Carlo calculations and those measured by short-exposure thermoluminescence dosimetry. Poor agreement was found between the calculational results and doses measured by exposure of LiF optical-absorption-type… more

Reaction of the Topopah Spring Tuff with J-13 water at 120{sup 0}C

Description: This report describes a series of hydrothermal experiments using crushed tuff from the Topopah Spring Member and natural ground water from well J-13. The purpose of these experiments is to define the changes in water chemistry that would result from temperature changes caused by emplacing high-level nuclear waste in a repository in the Topopah Spring tuff. Experiments were conducted at 120{sup 0}C in Teflon-lined reaction vessels at four separate rock-to-water ratios and for reaction times up t… more

Panel report on coupled thermo-mechanical-hydro-chemical processes associated with a nuclear waste repository

Description: Four basic physical processes, thermal, hydrological, mechanical and chemical, are likely to occur in 11 different types of coupling during the service life of an underground nuclear waste repository. A great number of coupled processes with various degrees of importance for geological repositories were identified and arranged into these 11 types. A qualitative description of these processes and a tentative evaluation of their significance and the degree of uncertainty in prediction is given. S… more

Americium thermodynamic data for the EQ3/6 database

Description: Existing thermodynamic data for aqueous and solid species of americium have been reviewed and collected in a form that can be used with the EQ3/6 database. Data that are important in solubility calculations for americium at a proposed Yucca Mountain nuclear waste repository were emphasized. Conflicting data exist for americium complexes with carbonates. Essentially no data are available for americium solids or complexes at temperatures greater than 25{sup 0}C. 17 references, 4 figures.

Rate of Pu(IV) polymer formation in nitric acid solutions. A parametric study

Description: The kinetics of Pu(IV) polymer formation has been examined with the intent of developing a simple mathematical equation that would predict the appearance of polymer. The fundamental polymerization rate has been found to be dependent on [Pu(IV)]{sup 1} {sup 2} and [HNO{sub 3}]{sup -6}. The activation energy for polymer formation is real temperature dependent, varying from 66.9 kJ/mol (16 kcal/mol) at 25{sup 0}C to 150.5 kJ/mol (36 kcal/mol) at 105{sup 0}C. These relationships have guided the dev… more

Geothermal Orientation Handbook

Description: This is a useful overview of the Department of Energy's outlook on geothermal energy development in the U.S. as of late 1983. For example, Exhibit 4 shows how electric utility planners' estimates of likely amounts of geothermal power on line for 1990 and 2000 first increased and then declined over time as they were surveyed in 1977 through 1983 (date are from the EPRI Survey). Additions to direct heat uses in 1979 through 1981 are in Exhibit 7. A Table (not numbered) at the back of the report "… more

THE GENERALIZATION OF A CIRCULAR BOUNDARY CONDITION IN THE PROGRAM POISSON TO INCLUDE NO SYMMETRY AND AXIS-SYMMETRY OF REVOLUTION

Description: We have previously reported on the incorporation of a circular boundary condition into the program POISSON for two-dimensional problems (Incorporation of a Circular Boundary Condition into the Program POISSON, S. Caspi, M. Helm, and L.J. Laslett, LBID-887, SSC MAG Note-S, February 13, 1984). The least square method has now been generalized to accept any suitable set of orthogonal functions which can describe the vector potential function outside a circular boundary so located that no external s… more

Final Report: Phase II Geothermal Exploration and Geothermal Power Plant Update for Ascension Island, South Atlantic Ocean

Description: The Phase I study of the geothermal potential of Ascension Island concluded that the possibility of a geothermal resource existing under the island was excellent. This conclusion was based on the presence of young volcanic rocks (a heat source close to the surface), an ample supply of water from the sea, and high permeability of many of the rocks which make up the island. The assumption was made that the resource would be similar to geothermal systems in the Azores or Japan, and a conceptual de… more

Description: This technical report on the Phase II geothermal exploration of Ascension Island documents the data collected during thermal gradient drilling and the subsequent thermal and fluid chemical investigations. It also documents the completion of the Phase II exploration strategy which was proposed at the end of the Phase I--Preliminary Examination of Ascension Island. The thermal gradient drilling resulted in seven holes which range from 206 to 1750 ft (53-533 m) deep, with a cumulative footage of 6… more

A technical and economic evaluation of thermal spallation drilling technology

Description: Thermal spallation of rock may be defined as a type of progressive rock failure caused by the creation of thermal stresses induced by a sudden application of heat from a high temperature source. This technology is applicable to only certain types of hard rock, such as dolomite, taconite, and granite. In 1981 and 1982, the deepest holes ever drilled by this process were drilled in granite to depths of 1086 feet and 425 feet respectively. Penetration rates at the bottom of the deeper hole reached… more
