An Electrochemical Approach to Predicting Corrosion Performance of Container Materials
The pitting potentials of nickel-rich Alloy 825 are measured in chloride-containing solutions at different temperatures and adjusted to different pH values. The pitting potentials were...

Future Supply of, and Demand for, Titanium, Copper and Lead
A literature survey has been conducted to assess the future world supply of, and demand for, titanium, copper and lead. These metals are candidates for the fabrication of containers for...

Variation of Permeability with Temperature in Fractured Topopah Spring Tuff Samples
Fractures will play an important role in the near-field hydrology of a nuclear-waste package in a mined repository. Our previous studies showed that the water permeability of fractured...

An Alternative Method to Mariotte Reservoir System for Maintaining Constant Hydraulic Pressure
Several problems with the Mariotte reservoir system were discovered when it was used to apply a constant water pressure as a boundary condition for a prolonged period. The constant-pressure...

Pore-Water Extraction from Unsaturated Tuffs Using One-Dimensional Compression
To support the study of the unsaturated-zone hydrochemistry at Yucca Mountain, Nevada, a one-dimensional compression system was developed and tested to extract unaltered and uncontaminated...

A Model for Effective Intergovernmental Planning
Effective intergovernmental planning processes are essential to the resolution of potential affects created by federal projects. In this paper, two successful planning efforts are described....

Building Consensus in Developing Radioactive Waste Management Systems
To successfully develop radioactive waste management systems, national authorities must work to establish consensus on numerous complex issues among many affected and interested parties....

Source Term Model for Radioactive Waste Repository
A radioactive waste repository source term model is developed to predict radionuclide release rates from solidified waste packages disposed of in underground repository. Leach rates, i.e.,...

Effects of Spent Fuel Aging on Repository Disposal Requirements
A study has been carried out to analyze the effects of extended spent fuel aging on spent fuel disposal requirements. The analysis considers additional spent fuel aging up to a maximum...

Evaluation of Alternative MGDS Development Strategies
A methodology has been developed to explicitly and quantitatively evaluate acceptable alternative repository development strategies, in terms of the degree to which they are likely to...

Determination of Cost Effective Waste Management System Receipt Rates
A comprehensive logistics and cost analysis has been carried out to determine if there are potential benefits to the high-level waste management system for receipt rates other than the...

Performance Assessment Calculational Exercises (PACE-90): Overview and Summary
PACE-90 was undertaken by the Yucca Mountain Site Characterization Project in order to develop expertise in computational capabilities and to aid in identification of critical elements...

Regulatory Systems-Based Licensing Guidance Documentation
The U.S. Nuclear Regulatory Commission (NRC) has developed a series of licensing guidance documents based on the regulatory requirements in Part 60 of Title 10 of the Code of Federal Regulations...

Location and Assessment of Groundwater Discharge
Methods have been developed for locating and measuring groundwater discharges, which are often obscured by the presence of overlying surface water. A sediment probe, towed behind a moving...

An Empirical Data Base for the Investigation of Earthquake-Related Changes in Crustal Hydrology
Both fracture permeability and fluid flow velocity can alter as a result of sudden strain changes associated with earthquake fault rupture. Testing the hydrological signatures of numerous...

The Shaft Excavation Effect Experiment
The Shaft Excavation Effect (SEE) experiment has been carried out by Power Reactor and Nuclear Fuel Development Corporation (PNC). Corresponding to this experiment, an evaluation system...

Two Double Porosity Models for Groundwater Radioactive Contamination
This paper describes two models for groundwater radioactive contamination in a naturally fractured rock. The first one for a saturated rock and the other one for an unsaturated rock. Numerical...

The Last Twelve Months at Yucca Mountain
The U.S. Department of Energy (DOE) is evaluating Yucca Mountain in Nevada to determine if the site would be a safe location for a high-level radioactive waste repository. As mandated...

Being Responsive and Getting the Job Done Right
The United States Department of Energy (DOE) Yucca Mountain Site Characterization Project Office (YMSCPO) has been given the responsibility for characterization of the potential repository...

An Integrated Systems Approach to Institutional/Technical Program Milestone Planning and Implementation in the Civilian Radioactive Waste Management Program
A broad spectrum of public and private sector institutions in the United States has concerns about the high-level radioactive waste management program. An integrated systems approach is...
