A Model to Predict the Production Rate of AMD
Results generated from a model to deterministically calculate the production rate of acid mine drainage compared to those generated by an empirical model are nearly identical. The model...

Wetlands for Acid Mine Drainage Treatment
Wetlands are being constructed on mined lands to treat acid mine drainage. Most of these wetlands remove a substantial amount of iron and sulfate from the water, but manganese removal...

Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...

Ash Disposal at Coal Creek Station
This paper outlines the effort of two utilities to minimize the impact of an 1100 megawatt lignite fired plant's waste stream on the environment. Current regulations, poor...

Beneficial Use of Coal Ash as a Structural Fill
For decades, electric utility companies have and will continue to dispose of their coal ash in various waste disposal sites. In the state of Pennsylvania, the Beneficial Use of Coal Ash...

EPA's Development of Environmental Standards for High-Level and Transuranic Wastes
EPA is in the process of developing standards for the disposal of high-level and transuranic wastes. This development process is in response to a Court order that remanded standards that...

First Update to the U.S. Nuclear Regulatory Commission's Regulatory Strategy for the High-Level Waste Repository Program
The U.S. Nuclear Regulatory Commission (NRC) staff has updated its initial regulatory strategy for the High-Level Waste Repository Licensing Program. The update describes changes to the...

Regulatory Issues Impacting the U.S. High-Level Radioactive Waste Management Program
This paper addresses current key regulatory issues impacting the U.S. high-level radioactive waste management program. The following issues pertain to the licensing of a geologic repository:...

Safety Assessment of Radioactive Waste Disposal: A Priority Area for International Co-operation Within the OECD Nuclear Energy Agency
The OECD/NEA programme in the radioactive waste management area gives a high priority to long-term safety aspects of radioactive waste disposal practices. Overall aims of this part of...

OCRWM Transportation Technical Activities for 1998
The Office of Civilian Radioactive Waste Management is preparing for the transport of spend fuel by 1998 from commercial reactors to a monitored retrievable storage facility. The preparations...

Development of the ASME/NUPACK Code
A Committee has been active for 10 years to develop Code rules for the design, construction and in-service requirements of containment systems for nuclear spent fuel and high level radioactive...

Certifying the TN-BRP and TN-REG Transportable Storage Demonstration Casks
The U.S. Department of Energy (DOE) has obtained U.S. Nuclear Regulatory Commission (NRC) certification to transport two transportable storage casks for a demonstration project. Because...

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...

High-Capacity, High-Strength Trailer Designs for the GA-4/GA-9 Casks
General Atomics (GA) is developing final designs for two dedicated legal-weight trailers to transport the GA-4 and GA-9 Spent-Fuel Casks. The basic designs for these high-capacity, high-strength...

Approach for Implementing Burnup Credit in High-Capacity Truck Casks
General Atomics (GA) will be submitting an application for certification to the U.S. Nuclear Regulatory Commission (NRC) for the GA-4 and GA-9 Casks in 1992. To maintain a capacity of...

Volcanic Episodes Near Yucca Mountain As Determined by Paleomagnetic Studies at Lathrop Wells, Crater Flat, and Sleeping Butte, Nevada
It has been suggested that mafic volcanism in the vicinity of Yucca Mountain, Nev., is both recent (20 ka) and a product of complex 'polycyclic' eruptions. This...

⁴⁰Ar/?⁹Ar Laser Fusion and K-Ar Ages From Lathrop Wells, Nevada, and Cima, California: The Age of the Latest Volcanic Activity in the Yucca Mountain Area
K-Ar and ⁴⁰Ar/³⁹Ar ages from the Lathrop Wells volcanic center, Nevada, and from the Cima volcanic field,...

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...

Weapons Test Seismic Investigations at Yucca Mountain
Yucca Mountain, located on and adjacent to the Nevada Test Site, is being characterized as part of an ongoing effort to identify a potential high-level nuclear waste repository. This site...

Tools for LWR Spent Fuel Characterization: Assembly Classes and Fuel Designs
Tools for the classification of fuel assembly types have been developed during the development of the Characteristics Data Base. The assembly class scheme is based upon the design of the...
