Effect of a Low-Permeability Layer on Calculated Gas Flow at Yucca Mountain
Yucca Mountain is being studied to determine its suitability as a location for a high-level nuclear waste repository. The mountain is a steep-sided linear ridge which is underlain by a...

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...

The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...

Application of TQM to the Waste Management QA Regulatory Arena
Over the past several years, a number of the scientists involved with the high-level radioactive waste repository project have expressed concern regarding the application of quality assurance...

The Licensing Support System (LSS): Who Should Operate it and Will it Work?
The development of the mammoth Licensing Support System (LSS), a management information system intended to handle documentation relevant to the licensing application of the DOE for the...

The Licensing Support System: Institutional Challenges and Opportunities
The Licensing Support System (LSS) is an electronic information management system which will be used in the Nuclear Regulatory Commission's (NRC) review of the Department...

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...

An Integrated Systems Approach to Institutional/Technical Program Milestone Planning and Implementation in the Civilian Radioactive Waste Management Program
A broad spectrum of public and private sector institutions in the United States has concerns about the high-level radioactive waste management program. An integrated systems approach is...

Modelling of Excavation, Thermal Loading and Bentonite Swelling Pressure for a Waste Repository
For the performance assessment of a future nuclear waste repository, the excavation of the tunnel and deposition hole, thermal loading from waste heat release and the swelling pressure...

Scenario Evolution: Interaction Between Event Tree Construction and Numerical Analyses
Construction of well-posed scenarios for the range of conditions possible at any proposed repository site is a critical first step to assessing total system performance. Event tree construction...

A Formalism to Generate Probability Distributions for Performance-Assessment Modeling
A formalism is presented for generating probability distributions of parameters used in performance-assessment modeling. The formalism is used when data are either sparse or nonexistent....

Site and Facility Waste Transportation Services Planning Documents
The Office of Civilian Radioactive Waste Management (OCRWM) will eventually ship Purchasers' (10 CFR 961.3) spent nuclear fuel from approximately 122 commercial nuclear facilities....

A Preliminary Evaluation of the Ability of From-Reactor Casks to Geometrically Accommodate Commercial LWR Spent Nuclear Fuel
The Department of Energy has sponsored a number of cask design efforts to define several transportation casks to accommodate the various assemblies expected to be accepted by the Federal...

Three-Dimensional Thermal Analysis for Temperature Distribution in Geological Formation
A three-dimensional conduction heat transfer program has been developed for use on microcomputer for thermal analysis of a conductive medium subject to, finite length heat sources. The...

System Analysis Dual-Purpose Repository New Results of Temperature Calculations
As design concept for a high-level waste (HLW) final repository the emplacement of reprocessing wastes and spent fuel elements of different types in a common repository is being studied...

Interim Storage of Solidified High Level Wastes
Indian approach to the problem of interim storage of vitrified high level wastes, indicating design philosophy adopted for air cooled vault at Tarapur has been described. Important design...
