A Look Back in Time to Verify Life Cycle Cost Analyses
The proper engineering design of any hydraulic structure requires consideration of different but interrelated fields of: 1) Planning, 2) Hydrology, 3) Hydraulics, 4) Structural, 5) Installation,...
Life Cycle Cost Analysis Discount Rates and Inflation
Life Cycle Cost Analysis techniques are useful for comparing alternatives that have differing cash flows over the expected life of a project. The selection of an appropriate discount rate...
Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
Shop Drawings: In Need of Respect
Engineer Robert L. Boehmig voices his concerns regarding the preparation of structural shop drawings. He gives his view of the shop drawing's role in construction projects,...
Managing Local Socioeconomic Impacts Through Project Management Policies Concerning Subsidized Transportation, Site Access, and On-Site Housing
The Department of Energy (DOE) has a legislative mandate to avoid, minimize and mitigate any adverse impacts to local communities resulting from activities at the Yucca Mountain Repository...
A Proposed Methodology for Validating Performance Assessment Models for the DOE Office of Civilian Radioactive Waste Management Program
The Department of Energy (DOE) has developed a draft methodology for validating performance assessment models that will be used in the licensing of high-level waste repository systems....
Status of Integrated Performance Assessment of the Waste Packages and Engineered Barrier System
Performance assessment of the engineered barrier system for a nuclear waste repository combines information from relevant disciplines and predicts the net long-term performance of the...
TN28V High Capacity Cask for the Transport and Storage of Vitrified Wastes
When the option of reprocessing has been selected, closing of the fuel cycle implies the return shipment of reprocessing wastes back to the country of origin of the spent fuel, in particular...
A Numerical Study of Some Effects of Nuclear Fuel Waste Vault Construction and Closure on Evolution of Groundwater Flow Paths in the Geosphere
We have performed a series of three dimensional finite-element simulations on the sensitivity of the groundwater flow paths and travel times in a conceptual hydrogeological model with...
A Stratified Percolation Model for Saturated and Unsaturated Flow Through Natural Fractures
The geometry of the asperities of contact between the two surfaces of a fracture and of the adjacent void spaces determines fluid flow through a fracture and the mechanical deformation...
Simulation Modeling of Subsurface Development
This paper discusses the use of simulation modeling in analyzing subsurface development activities and estimating associated costs at the Yucca Mountain candidate repository site. Described...
The Analysis of Horizontal Cooling Enhancement for Nuclear Waste Container Emplacement
This paper presents a novel method for distributing the heat generated by waste containers emplaced in the proposed high-level nuclear waste site at Yucca Mountain, Nevada. The method...
Optimization Method for Dimensioning a Geological HLW Waste Repository
This method was developed by the CEA to optimize the dimensions of a geological repository by taking account of technical and economic parameters. It involves optimizing radioactive waste...
Trends in Waste Management Program Costs: An Evolution of Estimating Methods and Results
The purpose of this paper is to present a summary of how the program cost projections contained in the five TSLCC analyses performed to-date and the estimating methods used to make these...
Materials Selection Issues for Structural Components of Transportation Casks
Sandia National Laboratories (SNL) is evaluating the use of alternate materials (i.e. other than stainless steel) as structural components in nuclear spent fuel transportation casks. This...
Programmatic Challenges and the Value of Testing on the West Valley Demonstration Project's Vitrification Facility Design
The primary objective of the West Valley Demonstration Project (WVDP) is the solidification of approximately 2.1 million liters (560 thousand gallons) of high-level waste (HLW) which resulted...
An Overview of the Vitrification of Defense High-Level Waste at the Hanford Site
Nearly 63 percent of the nation's high-level nuclear waste has accumulated at the U.S. Department of Energy's (DOE) Hanford Site in Washington State. This accumulation...
The International Stripa Project: Technology Transfer From Cooperation in Scientific and Technological Research on Nuclear Waste Disposal
The Nuclear Energy Agency of the Organization for Economic Cooperation and Development (OECD/NEA) sponsors the International Stripa Project. The Stripa Project is open to participation...
The Status of the Site Characterization and Validation Program in Phase III of the OECD/NEA Stripa Project
In 1980, the International Stripa Project was organized under the aegis of the OECD Nuclear Energy Agency for the purpose of conducting research, at the Stripa mine in Sweden, related...
Application of Geophysical Methods for Fracture Characterization
