Looking Out for the Ratepayer
The national high level nuclear waste management program has reached a crisis. The Department of Energy is ready to proceed with underground testing, but they are prevented from doing...

Yucca Mountain Near Field Environment Considerations for Engineered Barrier System Design and Performance
Waste emplacement environment will be essentially dry for at least 300 years and will likely continue to be dry for more than 1000 years, both as a result of the unsaturated ambient conditions...

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...

Effect of Ionizing Radiation on the Waste Package Environment
The radiolytic production of nitrogen oxides, nitrogen acids and ammonia are discussed in relation to the expected environment in a high-level waste repository that may be constructed...

Isotopic Discontinuities in Ground Water Beneath Yucca Mountain, Nevada
Analytical data for stable isotopes in ground water from beneath Yucca Mountain, when examined in map view, show areal patterns of heterogeneity that can be interpreted in terms of mixing...

General Circulation Models: Applications for Nuclear Waste Repositories
Numerical models have long been used to relate causal and response functions in the natural environment. Some 20 years ago, one-dimensional, multi-causal models of earth temperature evolved,...

Archaeological Program for the Yucca Mountain Site
Archaeological surveys, limited surface collections and selected test excavations in the Yucca Mountain Project Area have revealed four distinct aboriginal hunting and gathering adaptive...

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...

An Approach to Assessing the Impacts of Incident-Free Air and Highway Transportation of Radioactive Materials
Annual radiation doses and risks were calculated for shipments of radioactive materials both in passenger aircraft and on highways, under accident-free and incident-free conditions, i.e.,...

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...

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...

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...

Evaluation of Storage/Transportation Options to Support Criteria Development for the Phase I MRS
The Department of Energy's (DOE) Office of Civilian Waste Management (OCRWM) plans to develop an interim storage facility to enable acceptance of spent fuel in 1998. It is...

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...

A Decision Support System for Performance-Based Site Characterization
The complex and dynamic requirements of site characterization present a major management challenge. ParaTrac, a regulatory and technical information system, is described as a valuable...

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...

Visualizing the Performance of Structural Optimization Processes
Graphical constructions are discussed that enable the performance of iterative structural optimization processes to be evaluated visually. The first, a basins of attraction construction,...

Reservation Rebirth?
Slightly under one million American Indians live on reservations�legally sovereign nations that occupy a total land area the size of New England. Unbound by county and state environmental...
