Plans for Characterization of the Potential Geologic Repository Site at Yucca Mountain, Nevada
Site investigations in the vicinity of the potential repository site at Yucca Mountain, Nevada, have occurred for many years. This is due to the proximity of the potential repository site...
Surface-Based Site Characterization Testing to Determine the Suitability of the Yucca Mountain Site for a Nuclear Waste Repository
The Yucca Mountain Site in Nevada is currently being evaluated by the U.S. Department of Energy to determine its suitability for the first U.S. high-level radioactive waste repository....
Assessment of Natural Resources in Repository Siting
One way to discourage people from intruding into a repository for high-level radioactive waste is to locate it at a place that is not valuable for mineral resources. Thus, the Nuclear...
Geochemical Modeling: An Integrated Approach to Nuclear Waste Disposal Issues
To meet nuclear waste repository licensing requirements, the response of repository components and of the enclosing host rocks and fluids to temperature fluctuations, fluid flow, radionuclide...
Thermal Stability of Zeolitic Tuff from Yucca Mountain, Nevada
Thermal models of the potential repository at Yucca Mountain, Nevada, suggest that rocks near the potential host rock will experience elevated temperatures for at least 1000 yr. In order...
Drill-Back Studies Examine Fractured, Heated Rock
To investigate the effects of heating on the mineralogical, geochemical, and mechanical properties of rock by high-level radioactive waste, cores are being examined from holes penetrating...
Simulation of Heat Transfer in the Unsaturated Zone
It is well known that heat transfer can play an important roll in fluid flow near the emplacement site of high-level nuclear waste (K. Pruess and J.S.W. Wang, 1987). Heat transfer effects...
Systems Engineering Applied to a Regulatory Program
The Nuclear Waste Policy Act directs the Nuclear Regulatory Commission to complete the licensing hearing process for the High-Level Radioactive Waste Geologic Repository within three years,...
Analysis and Evaluation of Regulatory Uncertainties in 10 CFR 60 Subparts B and E
An attribute analysis scheme is presented for for prioritizing the resolution of regulatory uncertainties. Attributes are presented which assist in identifying the importance, need for...
Preparing a Safety Analysis Report Using the Building Block Approach
The credibility of the applicant in a licensing proceeding is severely impacted by the quality of the license application, particularly the Safety Analysis Report. An incomplete, unintelligible,...
Regulatory Considerations for Designing Surface Facilities for Yucca Mountain High-Level Waste Repository
This paper outlines U.S. Nuclear Regulatory Commission's (NRC's) key regulations applicable to U.S. Department of Energy's (DOE's) design...
Implementation of NUREG 1318 Guidance Within the Yucca Mountain Project
The U. S. Department of Energy's Yucca Mountain Project is implementing a quality assurance program that fulfills the requirements of the U. S. Nuclear Regulatory Commission...
Transportation Legend, Fact and Hysteria or, How to Dismantle a Mature Industry
In the rush to 'correct' the perceived deficiencies in the regulations covering the transportation of radioactive materials, many people, from legislators to...
What Will be the Engineered Barriers for Deep Disposal of High Level Radioactive Wastes in the Future?
Two sealing approaches are currently being developed in France for deep geological disposal of high-level wastes. One is based on the use of swelling clay in order to restore the initial...
A Description and Status of the Yucca Mountain Project Repository Sealing Program
Yucca Mountain is being characterized to determine its suitability as a site for a high-level nuclear waste repository. The repository would be located in the unsaturated zone in fractured,...
Simulation Modeling of Subsurface Development
This paper discusses the use of simulation modeling in analyzing subsurface development activities and estimating associated costs at the Yucca Mountain candidate repository site. Described...
The Analysis of Horizontal Cooling Enhancement for Nuclear Waste Container Emplacement
This paper presents a novel method for distributing the heat generated by waste containers emplaced in the proposed high-level nuclear waste site at Yucca Mountain, Nevada. The method...
Development of the Engineered Barriers for the Deep Geological Disposal of High-Level Radioactive Waste
Vitrified waste, overpack and buffer material are under research and development as engineered barriers in the deep geological disposal system of high-level radioactive waste. Static leach...
Systems Models for Predicting Radioactive Waste
This paper illustrates how a model can be constructed to analyze the growth of accumulated spent Light-Water-Reactor fuel using a technique from systems theory which has proved to be capable...
Near-Field Modelling for the Safety Assessment of French High-Level Waste Repositories
In assessing the safety of a French high-level waste repository, the fluxes of radionuclides released by the near-field into the geosphere are modelled by the CONDIMENT source code. This...
