The Growing Meet Market
The Delaware cities of Dover and Wilmington are only 5 mi apart. Their combined populations barely exceed 100,000. Yet each city is planning to build a new convention center to corner...
The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...
Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...
Development of the GA-4 and GA-9 Legal Weight Truck Spent Fuel Shipping Casks
General Atomics (GA) is developing two legal-weight-truck spent-fuel shipping casks for transporting commercial reactor spent fuel. The GA-4 pressurized-water-reactor (PWR) and the GA-9...
Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
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...
Controlling the Description of a High-Level Radioactive Waste Isolation System
Control of large, complex, regulation-driven programs using traditional management methods has not been wholly effective. What is needed is a rigorous yet flexible method that is amenable...
Mechanical Anisotropy of the Yucca Mountain Tuffs
Three series of measurements were performed on oriented cores of several Yucca Mountain tuffs to determine the importance of mechanical anisotropy in the intact rock. Outcrop and drillhole...
Application of Discrete Feature Analysis to Repository Characterization
Rock mass heterogeneity plays an important role in the hydrologic and mechanical behavior of radioactive waste repositories. This heterogeneity is, in turn, strongly influenced by the...
Fractal Characteristics of Fracture Roughness and Aperture Data
In this study mathematical expressions are developed for the characteristics of apertures between rough surfaces. It shown that the correlation between the opposite surfaces influences...
Design and Operating Criteria of the French Deep Repository for High Level Radioactive Waste
The design and operating criteria of the French geologic repository for high level radioactive waste (HLW) were selected for their contribution to operational and long-term safety, as...
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...
A Probe Method for Measuring In Situ Rock Thermophysical Properties
The application of a thermal probe method for in situ thermophysical property measurement is analyzed. The REKA method (Rapid Evaluation of k and alpha) involves a single-borehole probe...
Correlation of Hydraulic Conductivity and Sonic Velocity in Water-Saturated Tuff
A laboratory study was conducted to investigate the correlation of hydraulic and sonic properties of water-saturated tuff. The hydraulic test used a new rock block testing machine, which...
Perspectives on Integrating the U.S. Radioactive Waste Disposal System
The waste management systems being developed and deployed by the DOE Office of Civilian Radioactive Waste Management (OCRWM) is large, complex, decentralized, and long term. As a result,...
Management Systems Improvement Strategy for the Office of Civilian Radioactive Waste Management
To achieve the goal of permanent disposal of spent nuclear fuel and high-level radioactive waste, the U. S. Department of Energy's (DOE) Office of Civilian Radioactive Waste...
Field Investigations for Seismic Effects on Mechanical and Geohydrologic Response of Underground Structures in Jointed Rock
An exploratory Seismic Rock Mechanics research program has been initiated by the U.S. Nuclear Regulatory Commission at the Center for Nuclear Waste Regulatory Analyses (CNWRA) to study...
Building Consensus in Developing Radioactive Waste Management Systems
To successfully develop radioactive waste management systems, national authorities must work to establish consensus on numerous complex issues among many affected and interested parties....
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,...
Determination of Cost Effective Waste Management System Receipt Rates
A comprehensive logistics and cost analysis has been carried out to determine if there are potential benefits to the high-level waste management system for receipt rates other than the...
