Predicted Thermal and Stress Environments in the Vicinity of Repository Openings
An understanding of the thermal and stress environment in the vicinity of repository openings is important for preclosure performance considerations and worker health and safety considerations...
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...
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...
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...
Boundary Integral Methods for Unsaturated Flow
A boundary integral equation method (BIEM) is described for numerical analysis of quasilinear steady unsaturated flow in homogeneous material. The applicability of the exponential model...
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...
Modelling Studies for the Assessment of the Advanced Cold Process Canister
The Advanced Cold Process Canister (ACPC) is a new concept for the encapsulation of spent nuclear fuel for geological disposal. It consists of steel canister encased in a copper overpack....
Research Program to Develop and Validate Conceptual Models for Flow and Transport Through Unsaturated, Fractured Rock
As part of the Yucca Mountain Project, our research program to develop and validate conceptual models for flow and transport through unsaturated fractured rock integrates fundamental physical...
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.,...
Validation of Source-Term Models Using Natural Analogues
A comparison is made between the predicted distribution of copper calculated by the AREST source-term code and the measured profiles for copper surrounding a bronze cannon that was emplaced...
MARNIE, a Near Field Transport Model for Radioactive Waste Repositories
The long term safety of a final repository for radioactive waste disposal has to be demonstrated. A number of scenarios can be postulated that could lead to a considerable release of radionuclides...
Conclusions from Project-90 With Regard to a Regulatory Framework
A five year performance assessment program, Project-90 [1], has been concluded by the Swedish Nuclear Power Inspectorate, SKI. The project was defined to develop independent assessment...
CALIBRE and CRYSTAL: Near-field and Geosphere Models for Project-90
A new near-field model (CALIBRE) and a fractured geosphere model (CRYSTAL) have been developed in support of the Swedish Nuclear Power Inspectorate's Project-90 safety assessment...
Testing of Materials and Scale Models for Impact Limiters
Aluminum Honeycomb and Polyurethane foam specimens were tested to obtain experimental data on the material's behavior under different loading conditions. This paper reports...
GA-4/GA-9 Honeycomb Impact Limiter Tests and Analytical Model
General Atomics (GA) has a test program underway to obtain data on the behavior of a honeycomb impact limiter. The program includes testing of small samples to obtain basic information,...
Comparison of Elastic and Inelastic Analysis and Test Results for the Defense High Level Waste Shipping Cask
In the early 1980's, the U.S. Department of Energy/Defense Programs (DOE/DP) initiated a project to develop a safe and efficient transportation system for defense high level...
