Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...

Application of a Boundary Fitted Coordinate Mass Transport Model
A three-dimensional, boundary fitted coordinate, finite difference, mass transport model was applied to the Providence River in Upper Narragansett Bay, Rhode Island. The governing advection-diffusion...

Approximation of Convective Processes by Cyclic AOI Methods
Convective or advective processes play a role in many models for civil engineering applications. For example in transport equations, in hydrodynamic equations or wave energy equations....

A Method for Estimating the In Situ Cohesion of Cemented Conglomerate

Temperature Scenarios for a Repository at Yucca Mountain

Validation of the TEXSAN Thermal-Hydraulic Analysis Program

The Implications of Episodic Nonequilibrium Fracture-Matrix Flow on Site Suitability and Total System Performance

The Durability of Rubble Mound Armour in Service — A Case Study
Over the past decade, the ongoing monitoring of Gold Coast rubble mound structures in service has demonstrated a serious loss of durability over a period of time in the rock units after...

Mass Transfer of Volatile Contaminants in Showers

Characterization and Optimization of the Pultrusion Process for Structural Shapes

Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...

Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...

Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...

Application of Discrete Feature Analysis to Repository Characterization
Rock mass heterogeneity plays an important role in the hydrologic and mechanical behavior of radioactive waste repositories. This heterogeneity is, in turn, strongly influenced by the...

Key Scientific Issues for Near-Field Performance Assessment
This paper reviews key scientific issues related to the performance assessment of engineered barrier systems. In contrast to the inherent uncertainties associated with inhomogeneous geologic...

An Analysis of Buffering in Bentonite-Groundwater Systems
Chemical buffering by bentonite can potentially simplify assessments of the performance of engineered barriers to radionuclide migration by decoupling near-field and far-field geochemical...

Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...

Three-Dimensional Thermal Analysis for Temperature Distribution in Geological Formation
A three-dimensional conduction heat transfer program has been developed for use on microcomputer for thermal analysis of a conductive medium subject to, finite length heat sources. The...

The Constructive Use of Heat in an Unsaturated Tuff Repository
By designing the engineered barrier system in an unsaturated tuff repository to constructively use heat, the waste containers can be kept dry for hundreds of years. Without water, the...

A Proposed Regulatory Guide Basis for Spent Fuel Decay Heat
A proposed revision to Regulatory Guide 3.54, 'Spent Fuel Heat Generation in an Independent Spent Fuel Storage Installation' has been developed for the U.S. Nuclear...
