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,...
Exploratory Shaft Facility
This paper is an overview of engineering and concept development for the Exploratory Shaft Facility (ESF) of the Yucca Mountain Project. The paper presents a general description of the...
Role of Underground Testing to Determine Suitability of Yucca Mountain as a Potential Repository Site
A brief description of the Exploratory Shaft based site characterization testing program for the Department of Energy's (DOE) Yucca Mountain Project of the permanent disposal...
Smoothwall Blasting Planned for the Underground Research Facility at Yucca Mountain
At this time it is not known whether the Exploratory Shaft Facility (ESF) at Yucca Mountain, Nevada will be completely mechanically excavated, completely developed by drilling and blasting...
Rock Mechanics Aspects of the ESF Design
Selected aspects of the ESF rock mechanics design are outlined with emphasis placed on specific requirements imposed on the design process conducted within quality assurance-controlled...
Preliminary Methodology for Design of Stable Drifts for the Yucca Mountain Project
The Yucca Mountain Project is investigating the feasibility of locating a high-level radioactive nuclear waste repository at Yucca Mountain, Nevada. The conceptual design of the repository...
Basaltic Volcanic Episodes of the Yucca Mountain Region
The purpose of this paper is to summarize briefly the distribution and geologic characteristics of basaltic volcanism in the Yucca Mountain region during the last 10-12 Ma. This interval...
Volcano-Tectonic Interpretations: An Example from the Northern Basin & Range
Study of volcano-tectonic relationships in the Northern Basin and Range suggests a temporal relationship between basin propagation and the inception of volvanism. The age relationships...
The Area of Most Recent Volcanism Near Yucca Mountain, Nevada: Implications for Volcanic Risk Assessment
The proposed area of most recent volcanism (AMRV) includes all known post-6 Ma volcanic complexes in the Yucca Mountain area and encompasses the four volcanic centers in Crater Flat, the...
Incorporating Seismotectonic Data into Seismic Hazard Analyses
A wide range of seismotectonic data are now being incorporated into probabilistic seismic hazard analyses, supplementing the inadequately short historical seismicity record. This paper...
Kinematic Models of Extensional Structures: Seismic Implications
Kinematic models can relate faults of different types and different positions within a single dynamic system and thereby offer the potential to explain the disparate seismic activity characteristic...
Approach to Developing a Ground-Motion Design Basis for Facilities Important to Safety at Yucca Mountain
The DOE has proposed a methodology for developing a ground-motion design basis for prospective facilities at Yucca Mountain that are important to safety. The methdology utilizes a quasi-deterministic...
Synthesis of Studies for the Potential of Fault Rupture at the Proposed Surface Facilities, Yucca Mountain, Nevada
Published data for the Midway Valley area, the proposed site of the surface facilities of a high-level nuclear waste repository at Yucca Mountain, suggest that recognized regional faults...
Estimating Earthquake Sizes in the Basin and Range Province, Western North America: Perspectives Gained from Historical Earthquakes
Thirty eight historical earthquake from the Basin and Range province were used to examine three aspects of earthquake size and behavior: 1) the maximum background earthquake, 2) earthquake...
Iodine Transport Through the Soil-Plant-Atmosphere Continuum
The environmental assessment of the geological disposal of Canadian nuclear fuel waste involves transport modelling of radionuclides through the biosphere. Iodine-129 is a major fission...
A Preliminary Model for Carbon-14 Transport in a Clay Buffer
A model has been developed to assess the effect of calcite dissolution and precipitation reactions on the transport of 14C through a saturated, calcite-containing...
Natural Radionuclides in Groundwater From J-13 Well at the Nevada Test Site
The concentrations of U-238 and Th-232 chain members are extremely low in J-13 water, suggesting that their concentrations in groundwaters are largely governed by sorption/desorption processes....
Simulation of Reactive Chemical Transport in a Varying Thermal Field with Reaction-Flow Coupling
A computer program, THCVP, simulates coupling between advective/diffusive solute transport and chemical reactions, coupling of the reactions to heat transport, and feedback from precipitation/dissolution...
