Design Considerations for the Yucca Mountain Project Site Characterization
The Site Characterization Facilities (SCF) to be located in volcanic tuff at Yucca Mountain is a challenge to manage, design, and construct. This challenge is a result of a number of factors....
Design Reviews From a Regulatory Perspective
This paper presents views on the role of the licensing engineer in the design process with specific emphasis on design reviews and the automated information management tools that support...
Interpretation and Modelling Process of Bedrock Structures for Site Evaluation in Finland
The repository site for the final disposal of spent nuclear fuel in Finland will be selected by the end of the year 2000. Preliminary site investigations have been made in five areas since...
Characterization of High Radioactive Waste in a Reprocessing Plant Using Passive and Active Neutronic Methods
In the new UP3 reprocessing plant at LA HAGUE, drums containing hulls and endpieces are produced at the end of the shearing and dissolution shop. The determination of residual fuel masses...
Developing an Education Program for Schools on Radioactive Waste Management
United Kingdom Nirex Limited is responsible for the development of a deep disposal facility for Britain's solid low and intermediate-level radioactive wastes. In line with...
Public Education, Public Confidence, and Public Acceptance of Radioactive Waste Management Facilities
This paper critically examines the conventional assumption that public opposition is a function of public illiteracy and emotionalism by reviewing recent articles on radioactive waste...
Flow and Transport Around a Noncontinuous Horizontal Layer at Yucca Mountain
Computer simulations were used to examine the effect of a noncontinuous horizontal layer on the flow field and contaminant transport of a simplified conceptual model. The domain consisted...
Evaluation of Geoscientific Information Systems for Three-Dimensional Ground-Water Modeling, Yucca Mountain, Nevada
Fully three-dimensional representations of the geologic system at Yucca Mountain have been developed using a Geoscientific Information System, which is an expansion of a traditional Geographic...
Effect of Material Heterogeneities on Flow Through Porous Media
Modeling studies were conducted to determine the effects of material heterogeneities on the flow of water through rock. Multiple numerical calculations were made using random variations...
Unsaturated Flow Through a Variable Aperture Fracture in Topopah Spring Welded Tuff
The role of fractures in unsaturated flow through welded and nonwelded tuffaceous rocks is a fundamental question being addressed in performance assessment activities for the Yucca Mountain...
Transportation of Radioactive Materials Routing Analysis: The Nevada Experience
In 1987, the Nevada State Legislature passed a Bill requiring the Nevada Department of Transportation to develop and enforce a plan for highway routing of highway route controlled quantity...
Industry Experience and Programs that Benefit the Monitored Retrievable Storage (MRS) Facility Design
The design objectives and criteria for an MRS must be responsive to the needs and concerns of the public and the industry. It is shown here that to the maximum extent, existing industry...
Mechanistic Interpretation of Glass Reaction: Input to Kinetic Model Development
Actinide-doped SRL 165 type glass was reacted in J-13 groundwater at 90?C for times up to 278 days. The reaction was characterized by both solution and solid analyses. The glass was seen...
The Oregon Experiment: Public Information and Involvement
Oregon is neighbor to the Hanford Nuclear Site that now has the nation's largest store of radioactive waste. Oregon supports Hanford cleanup, which will require waste transport...
Development of a Structural Model to Analyze Public Opinion on a High-Level Radioactive Waste Facility
Studies show that Nevada residents and state officials oppose the proposed high-level radioactive waste repository project at Yucca Mountain. Nevada residents view the Yucca Mountain repository...
Major Results of Gravity and Magnetic Studies at Yucca Mountain, Nevada
About 4,000 gravity stations have been obtained at Yucca Mountain and vicinity since the beginning of radioactive-waste studies there in 1978. These data have been integrated with data...
Theory of Matrix and Fracture Flow Regimes in Unsaturated, Fractured Porous Media
The flow behavior of a two-dimensional, unsaturated fracture-matrix system is characterized by a critical flux qf*...
Barometric Pumping of Contaminated Gases Through Fractured Permeable Media
Contaminated gases may be transported vertically through a fractured permeable medium by the breathing process which is associated with cyclical changes in the barometric pressure. A review...
Key Scientific Issues for Near-Field Performance Assessment
This paper reviews key scientific issues related to the performance assessment of engineered barrier systems. In contrast to the inherent uncertainties associated with inhomogeneous geologic...
Some Conclusions from a Biospheric Model Validation Study (BIOMOVS)
BIOMOVS (BIOspheric MOdel Validation Study) is an international co-operative effort to test biospheric models designed to calculate the environmental transfer and bioaccumulation of radionuclides...
