Risk Of Radiation Exposure From The Transportation Of High-Level Nuclear Waste, Lawrence Banks

UNLV Theses, Dissertations, Professional Papers, and Capstones

Transportation of high-level nuclear waste poses a potential risk of exposure from radiation to people of Las Vegas and the surrounding environment. 77,000 metric tons of waste is scheduled to start arriving at Yucca Mountain in 2010. For 24 years legal weight trucks will transport high-level nuclear waste through 109 cities with populations over 100,000. The population of Las Vegas is over 400,000 people. In all, legal weight trucks will cross 43 states traveling millions of highway miles (see appendix B). The U. S. Department of Energy estimates expected radiological risk from accidents would be no higher than 0.003 latent …

Design And Analysis For Melt Casting Metallic Fuel Pins Incorporating Volatile Actinides, Xiaolong Wu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fundamental issues related to the selection of a metallic fuel casting furnace design are presented and discussed including heating mechanisms, casting issues, crucible design, and issues related to the mass transport of americium. The process of evaluating all of these different criteria is undertaken to select a concept that would have the greatest chance of success for casting americium in a metallic fuel rod. Based on this evaluation process, a concept for the casting of metallic fuel pins containing high vapor pressure materials is selected and discussed. The important physics of this concept include mass transport of americium from the …

A Study Of Obstacles To Use Of Methane Gas Produced In Landfills For Energy, Sharee Lynn Bowdidge

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study is to examine why landfill generated methane gas is not being treated as a resource, and used more widely as an energy source in the Southwestern United States. In this thesis, I have identified four possible barriers that may describe why this resource is not being used more often at landfill operations: 1) technological difficulties, 2) economic limitations, 3) regulatory constraints, and 4) insufficient desire to use. I have explored each of the possibilities in depth through case study interviews with individuals employed at six landfill operations, and individuals associated with landfill policy making. Although …

Rio Natural Gas, The Alternative Fuel Of The Future, Peter Garner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automobile exhaust is a major contributor of harmful air pollutants. Exhaust emissions include water (H2O), carbon dioxide (CO2), carbon monoxide (CO), nitrous oxides (NOX), sulfur oxides (SOX), hydrocarbons (HC), and particulate matter (PM), and of these the four major air pollutants are CO, HC, NOX, and PM. Particulate matter is predominantly emitted from diesel fuel burning vehicles. In order to aid in reduction of air pollution, and reduce dependence on foreign oil imports, federal legislation has been enacted. The two prominent acts are the National Energy Security Act in 1992, which mandates use of alternative fuels, and the Clean Air …

Las Vegas Flamigo Hilton/Unlv Environmental Studies Program Environmental Resource Analysis & Optimization Plan, Dennis Nowlin

UNLV Theses, Dissertations, Professional Papers, and Capstones

From 1987 through 1992 the Las Vegas Flamingo Hilton instituted resource efficiency improvements in electrical, natural gas, water and materials consumption. In 1992, the Flamingo Hilton commissioned the University of Nevada Las Vegas Environmental Studies Department to analyze and quantify the improvements made by The Flamingo Hilton and investigate the potential for further improvements.

Historical billing data from the periods 1987 - 1992 were used to analyze past and present (1992) electric, natural gas and water consumption. Materials disposal data was only available for a ten month period in 1992. Pollutant emissions data were supplied by Nevada Power Company.

A Comparative Analysis Of Viable Solar Thermal Technologies For Solar Field Development And Commercialization, Sean M. Crawford

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diminishing fossil fuels and concerns about the quality of the environment has lead the recent drive to establish a commercialized solar field in Southern Nevada. The competing solar thermal technologies for the Solar Enterprise Zone (SEZ) are Parabolic Dish-Stirling, Central Receiver Power Towers, and Parabolic Trough Systems. It is important to compare the technologies based on the guidelines set by the Corporation for Solar Technology and Renewable Resources. The variables weighted are solar conversion performances, initial capital investment, operation and maintenance costs, water and land use, and electricity production costs. All technologies have been proven to viable power sources and …

The Study Of Yucca Mountain For A Possible Nuclear Storage Facility Science Vs. Politics, Anna Leske

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to determine whether scientific or political methods were used by the of the United States Congress in the study of the nuclear waste storage facility in Yucca Mountain, Nevada. The history nuclear power and the history of the Johnston compromise that lead to the elimination of Texas and Washington States as possible sites for the repository is explained. A review of the conflicts between Nevada politicians and the U.S. Congress over the designation of Yucca Mountain as the sole study for a permanent storage site of the nation's high-level nuclear waste is addressed along …
