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...
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...
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...
Comparative Analyses of Spent Nuclear Fuel Transport Modal Options
The movement of nuclear waste can be accomplished by various transport modal options involving different types of vehicles, transport casks, transport routes, and intermediate intermodal...
Transportation Cask Life Cycle Cost Uncertainty Analysis
This paper demonstrates an uncertainty analysis methodology using random sampling. This methodology has been applied to a nuclear waste transportation code, and several transportation...
Analysis of RADTRAN Transportation Model
The RADTRAN computer model, used to estimate the risks of transporting waste to a high-level repository, is critically reviewed. Ignoring high consequence accidents, human error, sabotage,...
The Systems Integration Modeling System
The Systems Integration Modeling System (SIMS) is an analysis tool for the detailed evaluation of the structure and related performance of the Federal Waste Management System (FWMS) and...
A Systems Engineering Cost Analysis Capability for Use in Assessing Nuclear Waste Management System Cost Performance
The System Engineering Cost Analysis (SECA) capability has been developed by the System Integration Branch of the U.S. Department of Energy's Office of Civilian Radioactive...
Commercial Launch Facility Economic factors
Launch facility construction, maintenance and modification costs remain a largely invisible part of the cost of putting mass into orbit. The government can lease launch facilities to commercial...
Designed Experiments: An Interdisciplinary Approach to Space Education
The challenge of space is forcing engineering faculties to re-examine their roles in preparing college graduates to contribute to the space exploration and colonization effort. One of...
A Cost Study of Concrete Production on the Moon
In proposing and evaluating a construction system for a lunar base, the question of cost would be the most important one. Although it is not possible to conduct a detailed cost study at...
Alternatives for the U.S. Manned Space Program
There are a number of directions the U.S. space program could take. Should a space station be built? Should a lunar outpost be constructed? Should the U.S. plan a manned trip to Mars?...
Evaluation Plus History Equals Sewer Renovation
Sewers built in the 1920's were overflowing in the Fort Worth Zoo after moderate rain events. Data from A Sanitary Sewer Evaluation Survey (SSES), plus the Maintenance History...
Rehabilitation Model for Water Distribution Systems
This paper presents an optimization model for determining the minimum cost rehabilitation and replacement of pipes in water distribution systems. The advantages of the proposed model include...
Cost-Effective Maintenance and Replacement Scheduling
The paper discusses operations research approaches to scheduling maintenance on components of water resources infrastructure. Cost and reliability objectives are explicitly considered....
Models for Optimal Maintenance of Hydraulic Structures
Corrective maintenance includes the unscheduled repairs required to return a structure from a failed state to an operating or available state. Corrective maintenance is determined by the...
Economic Assessment of Infrastructural Development for the Gurara River in Nigeria
Based on the preliminary designs of the hydraulic structures for the proposed Gurara river water development project in Nigeria, an economic feasibility analysis is presented. The cost...
Financing Small Water Supply Projects in Colorado
In order to meet the water supply needs of Colorado communities and the requirements of the Safe Drinking Water Act of 1986, the Colorado Water Resources and Power Development Authority...
Appropriate Cost Factors for System Reliability
This paper examines the development of appropriate costs to be associated with various levels of failure of water distribution networks and water supply systems. A clear distinction is...
Weighting Factors for Transferable Discharge Permit Programs That Group Several Pollutants
Transferable discharge permit (TDP) programs for controlling several pollutants may manage such pollutants as several individual commodities or as a single weighted sum of the various...
