Effects of Core Sealing Methods on the Preservation of Pore Water
Five general core sealing methods (using Protecore, Lexan, wax, Protecore with wax, and Protecore with Lexan) were studied over a two year period to determine their moisture retention...

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...

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...

Radionuclide Transport in Fractured Media
Until recently, the classical advective-dispersive transport equation was considered to be an adequate model for describing the motion of a solute (e.g. radionuclides) in porous and fractured...

Perspectives on Out-of-Pool Spent Fuel Storage Requirements 1992-2036
The estimates of requirements for additional storage capacity for spent nuclear fuel from commercial LWRs in the United States are examined in this study. A comparison of this study's...

Evaluation of Spent Fuel Behavior Under Interim Storage Conditions in Russia
The nuclear power in Russia is based on three types of water cooled power reactors VVER-440, -1000 and RBMK-1000. Two fast sodium cooled reactors-prototypes BN-350 and BN-600 are in commercial...

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...

Dependence of Radionuclide Sorption on Sample Grinding Surface Area, and Water Composition
Experiments are described that were designed to quantify the dependence of sorption properties and surface area on the crushed-particle size of the rock samples used in batch sorption...

Research at Howard University on Retardation of Radionuclides by Sorption Processes During Host Rock?Ground Water Interactions
Extensive sorption measurements were made over a period of several years, of major radionuclides in J-13 Well water with Yucca Mountain tuff samples. Most of these measurements were single...

Diffusion of Sorbing and Non-Sorbing Radionuclides
Diffusion is considered one of the most important retardation mechanisms in fractured media. The diffusion experiments conducted involved solid tuff and groundwater from Yucca Mountain....

Summary of Revised Potentiometric-Surface Map for Yucca Mountain and Vicinity, Nevada
The revised map for the potentiometric surface of the uppermost saturated zone in Tertiary volcanic rocks at Yucca Mountain, Nevada, is based mainly on 1988 water levels. Refinement of...

Isotopic Evidence of Complex Ground-Water Flow at Yucca Mountain, Nevada, USA
Strontium isotopes (expressed as per mill deviation from mean sea water, ?⁸⁷Sr) reflect interaction between ground water and the aquifer through...

Late Quaternary History and Uranium Isotopic Compositions of Ground Water Discharge Deposits, Crater Flat, Nevada
Three carbonate-rich spring deposits are present near the southern end of Crater Flat, NV, approximately 18 km southwest of the potential high-level waste repository at Yucca Mountain....

The SECO Suite of Codes for Site Performance Assessment
Modeling for performance assessment of the Waste Isolation Pilot Plant (WIPP) has led to development of the SECO suite of codes for groundwater flow, particle tracking, and transport....

Modeling of Saturated Zone at Yucca Mountain, Nevada
This paper presents preliminary results of groundwater modeling of the saturated zone in the vicinity of Yucca Mountain. The analysis used both a regional (approximately 250 ? 250 km)...

Borehole Security on the Yucca Mountain Project
A borehole security plan was developed and is being implemented to address safety, environmental protection and restoration, waste isolation, and security concerns related to boreholes...

Robust-Multibarrier Waste Package Thermal Evaluation
One of the key issues to be addressed in developing a successful permanent radioactive waste storage concept is the thermal effect due to the spent nuclear fuel (SNF). The thermal output...

A DAD Example: The Story of the Fourth Nuclear Power Plant in Taiwan
Over the past decade, nuclear power play an important role in help develop Taiwan's internationally recognized economy. The effort for putting the new nuclear power plant onto the grid...
