Characterization Uncertainty and its Effects on Models and Performance
Geostatistical simulation is being used to develop multiple geologic models of rock properties at the proposed Yucca Mountain repository site. Because each replicate model contains the...

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....

Historical Overview of Domestic Spent Fuel Shipments?Update
The information in this paper summarizes historic data on spent fuel shipments in the United States. The data are updated periodically to keep abreast of changes. Information on shipments...

Transportation Capabilities of the Existing Cask Fleet
This paper describes a number of scenarios estimating the amount of spent nuclear fuel that could be transported to a Monitored Retrievable Storage (MRS) Facility by various combinations...

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...

The Radiological Capacity of Transport Casks Loaded in a 2-Region Non-Uniform Pattern
The radiological capacity of spent fuel storage and transport casks can be increased by the use of non-uniform cask loading. There are many possible combinations of spent fuel burnup and...

Toward Linking Demographic and Economic Models for Impact Assessment
One of the objectives of the Yucca Mountain Project, in Southern Nevada, is to evaluate the effects of the development of a high-level nuclear waste repository. As described in the Section...

Forecasting Behavioral Response to a Repository from Stated Intent Data
To forecast repository-induced behavior from surveys of behavioral intention, we develop a model of the relation between stated intent and actual propensity. This model relies heavily...

Circuitous Routings: Integration of Public Acceptability with Technical and Economic Feasibility
Public acceptance of agency plans for shipment of radioactive wastes to disposal facilities may be critical to efforts to site geologic repositories. Local and state participation in route...

Payments-Equal-to-Taxes (PETT): An Interpretation of Sections 116(c) (3) and 118(b) (4) of The Nuclear Waste Policy Act of 1982, as Amended
The opinions expressed in this paper are those of the authors and not necessarily those of either the U.S. Department of Energy or of Deloitte & Touche. The Payments-Equal-To-Taxes...

Some Political Logistics of Nuclear Waste
The need for a centralized, federal, interim storage facility for nuclear waste, or MRS, alledgedly has become more urgent because the date for the opening of the permanent repository...

The MD Design?A Cool Concept for Geologic Disposal of Radioactive Waste
The scheduled disposal capacity for spent nuclear fuel and other high-level radioactive wastes (HLW) is inadequate and the estimated supply of recoverable uranium for continued nuclear...

Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...

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...

The Constructive Use of Heat in an Unsaturated Tuff Repository
By designing the engineered barrier system in an unsaturated tuff repository to constructively use heat, the waste containers can be kept dry for hundreds of years. Without water, 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...

The Technical Challenge of Mechanized Excavation for Nuclear Waste Repositories
The requirements of mechanized tunnelling and shafting techniques within this newly developing field, namely the excavation of Nuclear Waste Repositories, will challenge the designers...

Recent Development in the Design of Hard Rock Tunnel Boring Machines for the Mining Industry
Underground development for nuclear waste storage will possibly require tunnels to be excavated in a variety of rock conditions and configurations. Recent innovations in Tunnel Boring...

Mechanical Tunnel Excavation in Welded Tuff
The Technical Review Board for the United States high-level radioactive waste facility at Yucca Mountain has recommended maximum use of 'the most modern mechanical excavation...

A First Look at Roadheader Construction and Estimating Techniques for Site Characterization at Yucca Mountain, Nevada
The Yucca Mountain site characterization program will be based on mechanical excavation techniques for the mined repository construction and development. Tunnel Boring Machines (TBM's),...
