Development of an inter-layer solute transport algorithm for SOLTR computer program. Part 1. The algorithm

Description: In order to perform studies of the influence of regional groundwater flow systems on the long-term performance of potential high-level nuclear waste repositories, it was determined that an adequate computer model would have to consider the full three-dimensional flow system. Golder Associates' SOLTR code, while three-dimensional, has an overly simple algorithm for simulating the passage of radionuclides from one aquifier to another above or below it. Part 1 of this report describes the algorith… more

Energy analysis of geothermal-electric systems

Description: Standard energy analysis was applied to 4 types of geothermal-electric technologies: liquid dominated, hot dry rock, geopressure, and vapor dominated. It was found that all are net energy producers. Expected uncertainties are not large enough to threaten this conclusion. Vapor dominated, the only technology in current commercial use to produce electricity in the US, has the highest energy ratio (13 +- 4). These results for energy ratio are equal to or less than some from other workers. In the c… more

Instrument evaluation, calibration, and installation for the heater experiments at Stripa

Description: Borehole instrumentation for the measurement of temperature, displacement, and stress was evaluated, modified, calibrated, and installed in an underground site at Stripa, Sweden where experiments are currently underway to investigate the suitability of granite as a storage medium for nuclear waste. Three arrays of borehole instrumentation measure the thermomechanical effects caused by electrical heaters which simulate the thermal output of canisters of radioactive waste. Because most rock mecha… more

Accuracy of various alternate methods of calculating total mass flow rate for PKL instrumented pipe spool prototype tests in single- and two-phase steam-water flows

Description: Instrumented spool pieces for installation in the piping of the German Primarkreislauf (PKL) test reactor have been designed and tested. The primary objective of the spools is to provide measurements of two-phase steam-water flow parameters (pressure, temperature, velocity) from which mass flow rates can be calculated. Each spool contains a three-beam densitometer, flow turbine, drag screen, and pressure and temperature sensors. The spools were prototype tested in single- and two-phase steam-wa… more

Modeling approaches to long-run integrated technological impact analysis

Description: Analysis of the energy-economic-environmental impacts of energy policies, such as a major synthetic fuels program, requires methodologies that reflect the potential benefits and costs of proposed policy alternatives. Energy policies typically have secondary economic and environmental effects as well as direct effects on energy itself, and these must collectively be assessed to provide a complete basis for policy selection. The focus of this report is on approaches to the analysis of long-term i… more

Recovery of anaerobic digestion after exposure to toxicants. Final report

Description: The concept that methane fermentation cannot tolerate chronic or slug doses of toxicants has almost totally precluded methane fermentation as a viable contender for the treatment of industrial wastewaters. This study assayed a wide variety of toxicants, heavy metals, inorganic salts, organic chemicals, solvents, and antibiotics which are used in industrial processes and, therefore, appear in the industrial wastewaters therefrom. Toxicity was related to the reduction in methane production of a c… more
