Open Channels in Fractures Maintained by Deposition and Erosion of Colloids
Colloids initially suspended in the water in fractures can deposit onto the fracture surfaces, and will partially or fully clog the fracture. The amount of clogging will depend on whether...
Late Quaternary History and Uranium Isotopic Compositions of Ground Water Discharge Deposits, Crater Flat, Nevada
Three carbonate-rich spring deposits are present near the southern end of Crater Flat, NV, approximately 18 km southwest of the potential high-level waste repository at Yucca Mountain....
Subsurface Transport of Radioactive Material Using Adaptive Finite Elements
A finite element method which utilizes mesh adaptation is used to calculate transient groundwater flow and pollutant transport. Mass lumping and reduced integration are employed to enhance...
Yucca Mountain Site Characterization Project Performance Based Q List
In mid-1992, the Yucca Mountain Site Characterization Project (YMP) initiated a performance based 'Q' List development effort. This effort is intended to evolve a 'Q' List based upon the...
Application of Quality Assurance to Site Characterization
Siting studies for nuclear power plants are conducted for the purpose of determining the suitability of the site (a natural system) on plant systems that prevent the release of radioactive...
Safeguards Issues of Radioactive Wastes at DOE Sites
Radioactive waste management is not regarded as a safeguard-sensitive step in the nuclear fuel cycle. However, the accumulation of large amounts of fissile materials in wastes over a period...
Safety Envelope Input: Nuclear Facility Isotopic Content (NFIC) Management System
The Westinghouse Savannah River Company (WSRC) is aggressively applying environmental remediation and radioactive waste management activities at the U. S. Department of Energy's (DOE)...
Cost and Schedule Baseline Management in the OCRWM Program
The Department of Energy's Office of Civilian Radioactive Waste Management has established a baseline change control system to support their program control system. The program control...
The Independent Cost Estimating Process
The United States Department of Energy (DOE) requires that an Independent Cost Estimate (ICE) be prepared for all Major Systems Acquisitions (MSAs); that is, projects or programs expected...
Robust-Multibarrier Waste Package Thermal Evaluation
One of the key issues to be addressed in developing a successful permanent radioactive waste storage concept is the thermal effect due to the spent nuclear fuel (SNF). The thermal output...
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...
Flow Visualization and Relative Permeability Measurements in Rough-Walled Fractures
Two-phase (gas-liquid) flow experiments were done in a natural rock fracture and transparent replicas of natural fractures. Liquid was injected at constant volume flow rate, and gas was...
Yucca Mountain Site Characterization Project Exploratory Studies Facilities Construction Status
This paper discusses the progress to date on the construction planning and development of the Yucca Mountain Site Characterization Project (YMP) Exploratory Studies Facilities (ESF). The...
Project Control?The Next Generation
The Yucca Mountain Site Characterization Project (YMP) is the U.S. Department of Energy's (DOE) second largest Major System Acquisition Project. We have developed an integrated planning...
Managing Government Contracts: Tips to Keeping Your Sanity
The key to managing large government projects is to divide it into smaller manageable pieces and organize it accordingly. Government projects are unique in that they require much more...
Glen Canyon: The Economic Costs
Revenues from power produced at Glen Canyon Dam are used to support Colorado River Storage Project (CRSP) purposes, to pay O&M costs, and to repay construction costs. Generation...
Wetland Engineering, Design, and Construction: State-of-the-Science and Research Needs
Local, state, and federal agencies, special interest groups, and individual landowners are undertaking wetland construction projects at a feverish pace to mitigate past and anticipated...
Innovative Wetlands in Urban Settings Using Dredged Material
As a result of its work in the waterways of the nation, the U. S. Army Corps of Engineers (USACE) has restored or constructed wetlands using dredged material in a number of urban/suburban...
The West Point Story?Chapter 1: Overview and Planning
The West Point wastewater treatment plant is the Seattle metropolitan area's largest wastewater treatment plant, and it is being upgraded to provide secondary treatment. The planning,...
The West Point Story?Chapter 2: Project Management Approach
In 1985, serving as the program lead, Metro contracted with Lewis Zimmerman Associates to conduct a formal facility planning effort for the West Point wastewater treatment plant. It was...
