Structural Considerations for a Radwaste Facility
The structural engineer needs to consider several criteria when designing a radioactive-waste processing facility in order to properly balance the requirements of safety and economy. This...
Civil Engineering Challenge with Nuclear Waste
The planning, design and construction of the ground surface facilities for a nuclear waste repository involves civil engineering in many ways. The transportation of heavy, metal shielded...
Innovtive Designs for Low-Level Nuclear Waste Disposal Trenches
Shallow land burial of low-level nuclear wastes presents many problems that are within the scope of civil engineering analysis and design. This paper presents the results of a U. S. Nuclear...
A Model for Nuclear Waste Shipping and Storage
A management option for spent fuel assemblies from nuclear power plants is storage in away-from-reactor (AFR) storage facilities. The purpose of this paper is to preseent a new mathematical...
Oconee Spent Fuel Rerack
Spent fuel storage problems facing electric utilities with nuclear generation are growing more critical as existing spent fuel storage capacity is utilized. Due to the inaccessibility...
Mass. Municipal Watershed Management?Case Study
Most of the estimated 200,000 acres of municipally-owned watershed land in Massachusetts currently suffers from a lack of wise, multiple-use forest management which has resulted in lost...
An Annual Water Balance for a Surface Mining Overburden Waste Embankment
The embankment contained a volume of 257 thousand cubic yards and resulted from a phosphate surface mining operation in southeastern Idaho. The elevation of the embankment is about 7500...
Urban Hydrology for Small Watersheds (Revised 1985)
Urban Hydrology for Small Watersheds, Technical Release 55, was first issued by the Soil Conservation Service in January 1975. It is a guide for SCS field personnel for estimating hydraulic...
A Methodology of Assessing Nonpoint Source Pollution from Agricultural Watersheds
Appraisals of water quality impacts induced by applying watershed management practices are difficult due to many factors. Lack of existing research data base, the diffusive characteristics...
A Giardia Source Investigation in a National Forest Municipal Supply Watershed
For nearly 100 years, the City of Missoula, Montana, obtained most of its municipal water from a surface water supply, Rattlesnake Creek. The Rattlesnake watershed lies within the Lolo...
Cyanide Heap Leaching Problems at Elk City, Idaho
A cyanide heap leaching operation for gold recovery was started in 1983 above the water intake for the community of Elk City in north central Idaho which turned into a problem during the...
Assessing Seepage at Uncontrolled Hazardous Waste Sites
This paper presents a conceptual framework for estimating the concentration of organic contaminants in a groundwater plume over time. The basis of this framework is the application of...
Water Balance Approach to Prediction of Seepage from Mine Tailings Impoundments, Part I: General Water Balance Approach
The prediction of seepage from a tailings impoundment requires careful evaluation because the predictions can have significant economic impact upon designs, as well as permit stipulations...
Water Balance Approach to Prediction of Seepage From Mine Tailings Impoundments, Part II: Theoretical Aspects of Water Balance Approach to Seepage Modeling and Detailed Case History Results
