Carbon-14: Some Evidence of Migration and Experiments on Immobilisation
Carbon-14 that is produced in nuclear reactors by reactions on C, N and O is one of the most biologically dangerous nuclides that are subject to global dispersion (H-3, 85-Kr, 129-I)....
Findings of the Secretary of Energy Advisory Board Task Force on Radioactive Waste Management
Secretary of Energy James D. Watkins created the Task Force on Radioactive Waste Management in April 1991. He asked the group then to recommend measures the Department might take to strengthen...
Determination of Water Content in Unsaturated Flow Experiments Using TDR and Capacitance
Electromagnetic techniques have been used for many years for the determination of moisture content in materials. We are adapting two of these techniques to the estimation of moisture in...
A Comparison of Geostatistically-Based Inverse Techniques for Use in Performance Assessment Analyses at the WIPP Site?Results from Test Case No. 1
The groundwater flow pathway in the Culebra Dolomite aquifer at the Waste Isolation Pilot Plant (WIPP) has been identified as a potentially important pathway for radionuclide migration...
Stochastic Simulation of Mass Transport in Heterogeneous Formations Using Hard and Soft Conductivity Data
The mass transport in a synthetic 2-D heterogeneous formation is simulated through the Monte-Carlo method using continuum approach. The simulated hydraulic conductivity field are generated...
Groundwater Flow Modelling for the TVO-92 Safety Analysis of Spent Fuel Disposal
The TVO-92 safety analysis of spent fuel disposal is based on preliminary site investigations carried out at five sites in Finland between 1987 and 1992. Groundwater flow analyses have...
Structure of Crater Flat and Yucca Mountain, Southeastern Nevada, as Inferred from Gravity Data
Existing gravity data in the vicinity of Yucca Mountain and Crater Flat have been examined to determine if these data support only the caldera model or if they support other geologic models...
Detachment Faults?Regulatory Implications for the Yucca Mountain Site
Site characterization investigations at the Yucca Mountain site, Nye County, Nevada consist of a combination of scientific data collection and analyses, and compliance with regulatory...
Geophycal Investigations of Buried Volcanic Centers Near Yucca Mountain, Southwest Nevada
Several aeromagnetic dipolar anomalies occur over flat, alluvial areas near Yucca Mountain that resemble anomalies typically associated with subaerial basaltic volcanic centers. Detailed...
Tourist Visitation Impacts of the Accident at Three Mile Island
This paper analyzes tourist impacts of the March 27, 1979, accident at Three Mile Island. A review of the literature, supplemented with recollections from Pennsylvanian public officials,...
Ambient Air Monitoring to Support HLW Repository Site Characterization
This paper is a description of the program that has been operating in support of the Yucca Mountain site site characterization activities since 1985.The ambient air monitoring is designed...
Functional Analysis: The Path to Effective Training
The regulatory requirements under which the Yucca Mountain Site Characterization Project (YMP) operates mandate that worker proficiency be achieved and maintained. Individuals performing...
Impact of Spatial and Temporal Data Limitations on the Modeling of Runoff Quantity and Quality
A small subbasin within an urbanized watershed (Reno, Nevada) was intensively monitored for runoff quantity and quality. The EPA Stormwater Management Model (SWMM) was applied to simulate...
Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....
Computer Application in Analyzing Change Order Work
In heavy construction, particularly on large tunnel projects, numerous tasks are often performed and inspected simultaneously. The project specifications and contract documents require...
Information Integrated Construction (IIC)
The term 'INFORMATION INTEGRATED CONSTRUCTION (IIC)' was coined to describe the integration of construction information and practice through computer technology. We define information...
Using Data Flow Diagrams to Study Communication Process Between Construction Project Participants
The Architecture-Engineering-Construction (AEC) industry is characterized as being highly fragmented. A large number of diverse organizations participate in the planning, design, and construction...
An Entity Relationship Model of Construction Project Data
The purpose of this paper is to demonstrate the results of applying techniques of information systems development to an application area that is diverse and complex but which is exploring...
Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...
The DWR Delta Graphical User Interface
Previously, most modeling development has been in the area of algorithms, with relatively little effort spent on conveying the results of models. A graphical user interface to a database...
