MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...

Thermal Strain Behaviour of Clays Cooled to Cryogenic Temperatures
The thermal expansion behaviour of two different types of clays (Boom clay from Belgium and a pure kaolinite-water paste) has been studied in a temperature range from +20? to -150?C (LNG...

Designing for Control of Ice Conditions in Marinas
Each marina or small-craft harbor experiencing ice during the winter months must be designed for site specific conditions. These conditions are governed by environmental factors (geology,...

Small-Scale Meteorology of Freezing Precipitation
Freezing rain and glazing are extremely disruptive to transportation, communication and power transmission. Local variations in the occurrence of freezing rain may be difficult to forecast....

Anelastic Straining in Polycrystalline Ice
This paper presents experimental observations on the influence of stress, grain size and total strain level on the magnitude of anelastic strain in granular freshwater ice. Cyclic loading...

Preliminary Results of Direct Tension Tests on First-Year Sea Ice Samples
We present the initial results of our tests to determine the tensile behavior of columnar sea ice over a range of temperatures extending from -20 to -3?C and strain rates of 10-5...

Exploring CO2 Emissions Reduction Strategies
Concern for potential climate change resulting from the greenhouse effect may be the biggest factor in energy planning in the 1990s. A 20% reduction in CO2,...

Electric Utility Planning for Greenhouse Concerns
International concerns for the potential of significant climate change resulting from the greenhouse phenomenon have focused increasing attention on the emissions of carbon dioxide and...

Improved Corrosion Protection for Flue Gas Systems Utilizing a Dual Liner Concept
A unique system of corrosion resistant materials has shown excellent performance and durability in flue gas systems for fossil plants, cogeneration plants, waste incinerators and waste-to-energy...

The Low Temperature Engine System?Status Report
Computer simulations have shown the Low-Temperature Engine System (LTES), a breakthrough in application of long-established thermodynamic principles, to offer double digit power output...

Determination of Diffusivities of Sorbing and Nonsorbing Species in Rocks
Through-diffusion experiments were performed for the sorbing and nonsorbing species in granites. Determining methods of diffusivities were discussed according to sorption properties of...

Effects of Heterogeneity on Actinide Diffusion Rates in Tuffaceous Rock
The pore structure and mineralogy of Topopah Spring Tuff are heterogeneous on scales less than one cm. This heterogeneity creates spatial variation in transport rates for aqueous actinide...

A Probe Method for Measuring In Situ Rock Thermophysical Properties
The application of a thermal probe method for in situ thermophysical property measurement is analyzed. The REKA method (Rapid Evaluation of k and alpha) involves a single-borehole probe...

Predicted Thermal and Stress Environments in the Vicinity of Repository Openings
An understanding of the thermal and stress environment in the vicinity of repository openings is important for preclosure performance considerations and worker health and safety considerations...

Durability, Mechanical, and Thermal Properties of Experimental Glass-Ceramic Forms for Immobilizing ICPP High Level Waste
The high-level liquid waste generated at the Idaho Chemical Processing Plant (ICPP) is routinely solidified into granular calcined high-level waste (HLW) and stored onsite. A research...

Regulatory Requirements and Long-Term Repository Host Rock Performance
The regulatory requirements governing the disposal of high-level radioactive wastes in mined geologic repositories acknowledge the long-lived nature of the wastes and require the consideration...

Modelling of Excavation, Thermal Loading and Bentonite Swelling Pressure for a Waste Repository
For the performance assessment of a future nuclear waste repository, the excavation of the tunnel and deposition hole, thermal loading from waste heat release and the swelling pressure...
