Testing Models of Flow and Transport in Unsaturated Porous Media
The design of an intermediate-scale flow and transport experiment in an unsaturated porous media is described. This experiment will be conducted a 3-m-diameter by 6-m-long caisson filled...
Simulation of Fracture Flow to the Kamaishi Validation Drift
The Power Reactor and Nuclear Fuel Development Corporation (PNC) has developed an in-situ test facility in the Kamaishi Mine to resolve technical issues in disposal of radioactive wastes...
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...
Field Investigation of Mining-Induced Seismicity on Local Geohydrology
Hydraulic response of the rock mass due to earthquakes is one of the concerns in the assessment of the long-term performance of a repository. Studies performed by other researchers indicated...
Single-Hole in Situ Thermal Probe for Hydrothermal Characterization at Yucca Mountain
The REKA thermal probe method, which uses a single borehole to measure in situ rock thermophysical properties and provides for efficient and low-cost site characterization, is analyzed...
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...
Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...
Channel Network Models for Solute Migration and Dispersal
We introduce a class of channel-network models for solute migration and dispersal in saturated rock. In discussing the behaviour of any dispersive process it is necessary to compare and...
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...
Fission Product Distribution in Nuclear Test Cavities/Chimneys
When a nuclear device is exploded, residual radioactive material is distributed throughout the resulting underground cavity and rubble chimney. Refractory materials are more concentrated...
Detachment Faults?Regulatory Implications for the Yucca Mountain Site
Site characterization investigations at the Yucca Mountain site, Nye County, Nevada consist of a combination of scientific data collection and analyses, and compliance with regulatory...
Seismic Reflection Profiling: Essential Geophysical Data for Yucca Mountain, Nevada
Yucca Mountain, Nevada, consists of a thick sequence of ashflow tuffs and lavas fractured into intact blocks with east-dipping strata, marginal broken zones characterized by dense faulting...
Characterization of Porosity in Support of Mechanical Property Analysis
Previous laboratory investigations of tuff have shown that porosity has a dominant, general effect on mechanical properties. As a result, it is very important for the interpretation of...
Large-Scale in Situ Heater Tests for Hydrothermal Characterization at Yucca Mountain
To safely and permanently store high-level nuclear waste, the potential Yucca Mountain repository site must mitigate the release and transport of radionuclides for tens of thousands of...
Micromechanics of Deformation in Topopah Spring Tuff, Yucca Mountain, Nevada
Samples of Topopah Spring tuff from Yucca Mountain, Nevada have been tested and analyzed. Laboratory tests conducted include standard uniaxial and triaxial compression tests, and special...
Core and Reaming Bit Studies in Yucca Mountain Tuffs
The Site Characterization Project is a major part of the work in determining the suitability of Yucca Mountain as a potential high level waste repository. Over 100 exploratory drill holes...
Experimental Studies to Calibrate Unsaturated Flow Models
Work is described that has been designed to serve as a laboratory calibration of numerical models for unsaturated flow studies. The experiment size is configured large enough that the...
Durability Testing of the High-Capacity GA-4/GA-9 Trailer
General Atomics (GA) is under contract to the US Department of Energy (DOE), Idaho Field Office, to develop two legal-weight truck from-reactor spent-fuel shipping casks with trailers....
Application of Indicator Geostatistics to the Gorleben Data Set
This paper describes a trial application of Indicator geostatistical methods to borehole data from the Gorleben site. Indicator variograms have been estimated from the site data and fitted...
