Assessments of System Impacts of Spent Fuel Thermal Characteristics and Emplacement Rates
Analyses conducted to evaluate the impacts spent fuel thermal characteristics and emplacement rates might have on the thermal conditions in a candidate geologic repository at the Yucca...
Recent Developments in Stochastic Modeling and Upscaling of Hydrologic Properties in Tuff
A set of detailed geostatistical simulations of porosity has been produced for a layered stratigraphic sequence of welded and non-welded volcanic tuffs at Yucca Mountain, Nevada. The simulations...
Dependence of Radionuclide Sorption on Sample Grinding Surface Area, and Water Composition
Experiments are described that were designed to quantify the dependence of sorption properties and surface area on the crushed-particle size of the rock samples used in batch sorption...
Fission Product Distribution in Nuclear Test Cavities/Chimneys
When a nuclear device is exploded, residual radioactive material is distributed throughout the resulting underground cavity and rubble chimney. Refractory materials are more concentrated...
A Numerical Analysis of Spent Nuclear Fuel Thermal Characteristics
A numerical analysis is presented comparing the thermal behavior of a spent boiling water reactor fuel pin and an electric heating element intended to simulate the fuel pin in an experimental...
Characterization of Porosity in Support of Mechanical Property Analysis
Previous laboratory investigations of tuff have shown that porosity has a dominant, general effect on mechanical properties. As a result, it is very important for the interpretation of...
Large-Scale in Situ Heater Tests for Hydrothermal Characterization at Yucca Mountain
To safely and permanently store high-level nuclear waste, the potential Yucca Mountain repository site must mitigate the release and transport of radionuclides for tens of thousands of...
Assessing Fault Rupture Hazard for the Proposed Repository at Yucca Mountain, Nevada: Demonstration of a Methodology Using Expert Judgments
As part of the Electric Power Research Institute's High Level Waste (EPRI HLW) performance assessment, we have developed and demonstrated a methodology to estimate the magnitude and likelihood...
Basin Scale Management of Surface and Ground Water
An important element in the economic development of many regions of the Great Plains is the availability of reliable water supply. The primary supply has tended towards developing groundwater...
Innovative Wetland Re-creation in Urban Setting
The project site is a 106 hectare, mixed-used, commercial development east of Tampa, Florida and at the westerly limit of the town of Brandon, Florida. Delaney Creek traverses the site...
Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...
Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...
Local Agency Regulation: The Policies and Process of Surface Water Protection
King County, Washington, adopted a Surface Water Design Manual in January 1990. This manual, which has served as a resource guide in developing similar manuals throughout the Pacific Northwest...
A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...
A Planning Strategy for Safe Drinking Water Act Compliance
This paper presents a simple planning strategy for drinking water utilities that will allow them to move ahead with system upgrades and specific regulatory compliance programs even though...
Water Resources Management Issues Confronting Developing Countries
Water resources planning, development and management in most of the developing and rapidly developing countries have been driven by consumer interest. The rapid urbanization, industrialization,...
Technical and Organizational Constraints on Surface and Groundwater Irrigation in Small-Holder Areas of S. Asia
Variable irrigation supply and the independent character of the S. Asian small-holder combine to present a difficult problem in irrigation management. Attempts to introduce advanced technology...
Artificial Recharge to Manage Groundwater Quality in a Connected Surface Water Groundwater System
Finite difference method is used to formulate the management problem of movement of water and solute in a connected surface water groundwater system. Pumped groundwater quality of conservative...
Storm Water Utility Experience in Bellevue, Washington
Surface water management is seen as a flood protector by most, a savior of the environment by some and a subversion of property rights by others. As recently as 20 years ago, there were...
CAD Applications for Material Handling in the Construction Environment
