Modeling of Strongly Heat-Driven Flow Processes at a Potential High-Level Nuclear Waste Repository at Yucca Mountain, Nevada
Two complementary numerical models for analyzing high-level nuclear waste emplacement at Yucca Mountain have been developed. A vertical cross-sectional (X-Z) model permits a realistic...

Modeling of the Ventilation for Emplacement Drift Re-Entry and Rock Drying
Different ventilation scenarios were analyzed for a hot repository with a 114 kw/Acre heat load, to determine the time required to cool a drift to the point where the temperature of the...

Organic Carbon Input in Shallow Groundwater at ?SP?, Southeastern Sweden
The variation in carbon and oxygen isotopes in calcite fissure fillings and dissolved carbonate from shallow groundwaters has been examined at Aspo, southeastern Sweden. The shallow water...

Modelling Colloidal Transport of Radionuclides Through Porous Media
General acknowledgement of the potential role of colloids in enhancing radionuclide transport has prompted the preliminary development of a mechanistic colloid transport model as part...

The Role of Fault Zone in Affecting Multiphase Flow at Yucca Mountain
Within Yucca Mountain, the potential High Level Nuclear-Waste Repository site, there are large scale fault zones, most notably the Ghost Dance Fault. The effect of such high-permeability,...

Studies of the Role of Fault Zones on Fluid Flow Using the Site-Scale Numerical Model of Yucca Mountain
The three-dimensional grid of the site-scale model developed for the unsaturated zone at Yucca Mountain was used to perform two-dimensional simulations with the TOUGH2 computer program....

Discontinuities, Rock Deformation and Fluid Flow Around Emplacement Rooms
One of the major concerns for the design of the potential nuclear waste repository at Yucca Mountain is how to identify the fast flow paths and how to minimize the flow of the fast paths....

Sensitivity and Probabilistic Analyses of Ground Water Travel Time in a Fractured and Variably-Saturated Geologic Medium
This paper presents a method for sensitivity and probabilistic analyses of performance of a hypothetical nuclear waste repository located in a layered, fractured, and variably-saturated...

Review and Selection of Unsaturated Flow Models
The Civilian Radioactive Waste Management System Management and Operating Contractor (CRWMS M&O) is conducting a thorough review and evaluation of existing flow and transport models....

Regulatory Issues for WIPP Long-Term Compliance with EPA 40 CFR 191B and 268
Before disposing of transuranic radioactive waste at the Waste Isolation Pilot Plant (WIPP), the United States Department of Energy (DOE) must evaluate compliance with long-term regulations...

Full-Field Dye Concentration Measurement Within Saturated/Unsaturated Thin Slabs of Porous Media
This paper presents a full-field dye concentration measurement technique that extends our experimental capabilities to the measurement of transient dye concentration fields within steady...

Determination of Water Content in Unsaturated Flow Experiments Using TDR and Capacitance
Electromagnetic techniques have been used for many years for the determination of moisture content in materials. We are adapting two of these techniques to the estimation of moisture in...

Inference of Moisture Content in Unsaturated Media Using Ultrasonics
This study focuses on the ability of commercial ulltrasonics equipment to determine the moisture content in unsaturated media. We are interested in the possible application of this technology...

Effect of Interconnection of Fractures on Dispersion in Flow Through Fractured Networks
A stochastic modeling technique in a 2-D discrete fracture network with two orthogonal sets of fractures is developed to investigate mass transport dispersion and to investigate the relation...

Flow and Transport in Hierarchically Fractured Systems
Preliminary results indicate that flow in the saturated zone at Yucca Mountain is controlled by fractures. A current conceptual model assumes that the flow in the fracture system can be...

Connectivity and the Continuum Approximation in Fracture Flow Modeling
The continuum assumption is frequently made when modeling flow in fractured media. The approach presented in this paper helps evaluating the validity of such an assumption. Two indices...

Modeling of Fluid and Solute Transport in Fractured Rock
A new model for flow and solute transport in fractured rock is proposed. It is based on the concept of a network of channels. The individual channel members are given stochastically selected...

Solute Transport Characteristics of Fractured Dolomite in Southern Nevada, USA
Recirculating tracer tests in fractured Cambrian dolomite beneath the Amargosa Desert revealed (1) and 83-percent increased in apparent dispersivity resulting from a two-percent increase...

Experimental Synthesis of Crystalline Matrices Based on Ce, Ba, Sr Zirconates for Immobilization of High-Level Radioactive Actinides
Experimental investigations are carried out at the Radium Institute to create different by their properties crystalline matrices, alternative to SYNROC, for incorporation of partitioned...

A Comparison of Geostatistically-Based Inverse Techniques for Use in Performance Assessment Analyses at the WIPP Site?Results from Test Case No. 1
The groundwater flow pathway in the Culebra Dolomite aquifer at the Waste Isolation Pilot Plant (WIPP) has been identified as a potentially important pathway for radionuclide migration...
