Testing and Evaluation of High Capacity, Multi-Strand Rock Anchors for Lake Lynn Dam
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...
Ultrafine Cement Tests and Drilling Warm Springs Dam
Ultrafine cement was chosen by the Corps of Engineers for tertiary grouting the Warm Springs Dam because of its ultrafine particle size, low settlement, medium viscosity and longevity....
Experimental Evaluation of Reservoir Bottom Remediation Material
Open trenches developed through a compacted clay liner on the bottom of a reservoir. An experimental investigation has been conducted to evaluate the feasibility of using silt-sized, nonplastic...
Seismic Stability Modification Requirements for Pineview Dam
Pineview Dam is located 8 km upstream from Ogden, Utah, and about 8 km from the Wasatch Fault Zone. Preconstruction information and construction records available at the outset of the...
The Causticity of Accelerator for Shotcrete and its Impairment on Strength of Shotcrete
How on earth is the toxic and caustic injury of accelerator for shotcrete to operators and animals? How about its impairment on strength of shotcrete? The paper gives some reports and...
Large Scale Testing of Shotcrete
A large scale test program was carried out to evaluate the relative roles of steel fiber and mesh reinforced shotcrete for hard rock stabilization. The most realistic conditions in a tunnel...
Principles for a Rational Design of Shotcrete Linings in Hard Rock
The rock load on a shotcrete lining is hard to determine. This fact, however, does not prevent from designing the lining in a rational and consequent way. The paper treats the problem...
Cask Storage Verification Test?Full Scale Test
In Japan, the cask-storage method of spent fuel will be licensed in the near future and the related R&D works (partly of the Japanese Government have been carried out mainly by...
The Most Likely Groundwater Flux Through the Unsaturated Tuff Matrix at USW H-1
Using a probabilistic inverse method, an estimate is made of the groundwater flux through the unsaturated tuff matrix at drill hole USW H-1 in Yucca Mountain. The most likely flux is found...
U.S. Nuclear Regulatory Commission Staff Technical Position on Investigations to Identify Fault Displacement Hazards and Seismic Hazards at a Geologic Repository
This paper outlines the guidance provided to the U.S. Department of Energy by the Nuclear Regulatory Commission (NRC) staff in its Staff Technical Position (STP) on appropriate investigations...
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...
