Radionuclide Migration as a Function of Mineralogy
The migration of radionuclides is studied as a function of mineralogy utilizing batch sorption and column experiments. The transport behavior of alkaline, alkaline-earth, and transition...
Durability, Mechanical, and Thermal Properties of Experimental Glass-Ceramic Forms for Immobilizing ICPP High Level Waste
The high-level liquid waste generated at the Idaho Chemical Processing Plant (ICPP) is routinely solidified into granular calcined high-level waste (HLW) and stored onsite. A research...
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...
Exclusion of Foreign Materials from the Savannah River Site (SRS) Canistered Waste Forms: Characterization of the Gas within the Free Volume
Glass-filled canisters, produced at the SRS Defense Waste Processing facility, must meet the Waste Acceptance Preliminary Specifications (WAPS) developed by DOE's Office of...
Behaviour of Plutonium, Rare Earth Elements and Elements of the Platinum Group in Vitreous Phosphate Composites During Liquid HLW Vitrification
The methods of ?-spectrometry, ?-scanning, ?-radiography, optical microscopy, x-ray phase and x-ray fluorescent analyses were used to study the behaviour of Pu, La, Ce, Nd, Sm, Ru, Rh,...
Analysis of Solute Transport in an Intermediate-Scale Unsaturated Flow Experiment
A simplified stochastic model was derived and applied to two unsaturated flow experiments conducted in an intermediate-scale caisson. Parameters for the flow and transport models were...
Potential Uses of Lead in Nuclear Waste Disposal
In order for lead to be considered as a nuclear waste packaging material, it must be shown that it has adequate corrosion resistance, and that it does not degrade the properties of other...
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...
The Chemical Stockpile Intergovernmental Consultation Program: Lessons for High Level Waste Public Involvement
This paper assesses the appropriateness of the U.S. Army's Chemical Stockpile Disposal Program's (CSDP) Intergovernmental Consultation and Coordination Boards...
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....
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...
Risk Assessments for the Design of Subsurface Openings
A probabilistic approach was introduced to assess the risk of structural instability due to rock joint systems in rock mass, where subsurface openings are excavated, such openings as shafts,...
Apparent and Simple Diffusion Coefficients in Compacted Bentonite
Diffusion coefficients were experimentally determined in bentonite to evaluate the effectiveness of bentonite layers as a diffusion barrier to ionic transport away from high-level radioactive...
An Analysis of Buffering in Bentonite-Groundwater Systems
Chemical buffering by bentonite can potentially simplify assessments of the performance of engineered barriers to radionuclide migration by decoupling near-field and far-field geochemical...
Assessing Impacts on Biological Resources from Site Characterization Activities of the Yucca Mountain Project
An integrated impact assessment program was developed to monitor the possible effects of Site Characterization Activities (SCA) on the biological resources of the Yucca Mountain area....
Site-Generic Approach for Performance Assessment of HLW Disposal System in Japan
This paper presents an overview of the preliminary performance analyses and description of R&D activities designed based upon the results of the analyses, which are to be incorporated...
The Long Climb to Remediation
During World War II, the Rocky Mountain Arsenal in Colorado served as an Army manufacturing center for the production, then destruction, of mustard gas, napalm, cluster bomb mixtures,...
Long Term Durability of Geomembranes
The most frequently asked question about geosynthetic materials is how long they will last. Precise answers, especially for geomembranes, elude researchers as well as manufacturers, design...
Aquifer Restoration: Which Method?
Ground-water contamination is an increasing problem, especially in large urban areas. Toxics that seep into water supplies threaten the health of the community and it's difficult...
Effect of Camera Geometry on Thermographs for Pavement Crack Detection
The research focused on the effects of camera heights and tilt angles on the ability to detect cracks in thermographs obtained with an infrared camera. Results indicate that differences...
