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...

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...

Transient Drainage from UMTRA Tailings

A Study of the Impact of the Dumping of Spoil on Beach Processes
The amenity value of beaches along the North East coast of England is reduced because of the continuing practice of dumping colliery spoil directly onto the beaches for dispersal by the...

Integrated Waste Management at the Weldon Spring, Missouri Site Remedial Action Project
The diversity of contaminants and contaminated media at the Weldon Spring, Missouri CERCLA site, located about 30 miles west of St. Louis, Missouri, necessitates the formulation of integrated...

Rio Moquino Stream Stability and Erosion Protection, Jackpile Uranium Mine
The uniqueness of the Jackpile Reclamation Project and the changes in reclamation technology over the past few years have prompted a reexamination of some of the design criteria specified...

The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System
Federal regulations for the surface mining of coal stress proper design and construction of stable waste rock disposal areas. A key to the long-term stability of these excess spoil fills...

Assessment of Fracture-Sampling Techniques for Laboratory Tests on Core
As part of the site characterization work to be done at Yucca Mountain in Nye County, Nevada, a candidate site for the first mined-geologic repository for high-level nuclear waste, laboratory...

Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...

Effects of Uranium Mining, Puerco River, New Mexico
Effluent from uranium-mine dewatering and acidic water released by a tailings-pond dike failure increased radionuclide activities in streamflow in the Puerco River in New Mexico and Arizona....

Preliminary Methodology for Design of Stable Drifts for the Yucca Mountain Project
The Yucca Mountain Project is investigating the feasibility of locating a high-level radioactive nuclear waste repository at Yucca Mountain, Nevada. The conceptual design of the repository...

Assessment of Natural Resources in Repository Siting
One way to discourage people from intruding into a repository for high-level radioactive waste is to locate it at a place that is not valuable for mineral resources. Thus, the Nuclear...

Role of Underground Testing to Determine Suitability of Yucca Mountain as a Potential Repository Site
A brief description of the Exploratory Shaft based site characterization testing program for the Department of Energy's (DOE) Yucca Mountain Project of the permanent disposal...

Ice Buildup in Tailing Basins

Repairs to Steel H-Piles at Mystic Pier No. 1, Charlestown, Massachusetts

Recent Progress in Coal Ash Utilization and the Effect of Environmental Issues and Regulations
This paper summarizes for civil engineers several publications that help to specify and use coal combustion by-products in construction and other applications in a technically sound, commercially...

Guidelines for Design and Construction of Pozzolanic Stabilized Base Course Mixtures
The American Coal Ash Association (ACAA) has developed a manual of recommended practice which contains guidelines for the design and construction of pozzolanic stabilized base course mixtures...

Residential Damage in an Area of Underground Coal Mining
In order to estimate the potential for future subsidence-related residential damage, a statistical analysis of past residential damage in the Boulder-Weld, Colorado, coal field was performed....

Highway Damage Due to Subsidence
In this study subsidence profiles over three longwall panels, which were mined beneath state highways in Southeastern Ohio, were obtained. Immediate and short term subsidences were recorded....
