Measured and Simulated Response of a Small Semisubmersible Moored in Deep Water
Small semisubmersible platform concepts are proposed for electronic tracking ranges, single-well petroleum production, and oceanographic data collection. This paper summarizes a major...
Current Blockage Effects on Model-Scale Offshore Platform
This paper presents analysis results of model tests on a 1:47 scale model of an offshore jacket structure under wave-plus-tow (representing wave-plus-current) conditions. The analysis...
Screening Old Offshore Platforms: Previous Approaches and Further Thoughts
Several possible levels of analysis are identified, each leading to both quantitative (economic) and subjective (human) risk evaluations. These range from ratings based only on historical...
Multiphase Flows and the Modeling of Drifting Snow
Three categories of multiphase flow theories are commonly specialized for modeling drifting snow; the 'two-fluid' model, particle tracking schemes and kinetic...
Recommended Cold Regions Meteorological Instrumentation
For nearly 30 years, CRREL has studied environmental conditions in winter weather. These efforts have concentrated on providing field-measured meteorological data and historical climatological...
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Failure Modes of Flat Bottom Vertical Storage Tanks
Flat bottom vertical storage tanks are important components in essential nuclear power plant safety systems. Data on the seismic capacity and failure modes of such tanks have been identified,...
Beyond Engineering: The Politics of Maracaibo
The Lake Maracaibo Bridge in Venezuela was built in 1959. It ranks as one of the largest and longest bridges in the world at the time it was built and contained the longest concrete cable-stayed...
Application of Discrete Feature Analysis to Repository Characterization
Rock mass heterogeneity plays an important role in the hydrologic and mechanical behavior of radioactive waste repositories. This heterogeneity is, in turn, strongly influenced by the...
Mineralogic Alteration History and Paleohydrology at Yucca Mountain, Nevada
The importance of paleohydrology to the Yucca Mountain Site Characterization Project derives from the role water will play in radioactive-waste repository performance. Changes in hydrologic...
Evaluation of Geoscientific Information Systems for Three-Dimensional Ground-Water Modeling, Yucca Mountain, Nevada
Fully three-dimensional representations of the geologic system at Yucca Mountain have been developed using a Geoscientific Information System, which is an expansion of a traditional Geographic...
Dry Drilling and Coring Development for Unsaturated Zone Studies
Two areas of major difficulty associated with characterization of any unsaturated zone are the conventional drilling and coring processes used to acquire the samples. These processes are...
Source Term Model for Radioactive Waste Repository
A radioactive waste repository source term model is developed to predict radionuclide release rates from solidified waste packages disposed of in underground repository. Leach rates, i.e.,...
The Adoption of Mechanized Excavation Techniques for the Superconducting Super Collider
The Superconducting Super Collider (SSC) is the latest and largest in a line of high-energy physics accelerator projects. The five increasingly energetic accelerators which make up the...
The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...
Comparison of Elastic and Inelastic Analysis and Test Results for the Defense High Level Waste Shipping Cask
In the early 1980's, the U.S. Department of Energy/Defense Programs (DOE/DP) initiated a project to develop a safe and efficient transportation system for defense high level...
An Empirical Data Base for the Investigation of Earthquake-Related Changes in Crustal Hydrology
Both fracture permeability and fluid flow velocity can alter as a result of sudden strain changes associated with earthquake fault rupture. Testing the hydrological signatures of numerous...
Strontium Isotopes in Carbonate Deposits at Crater Flat, Nevada
Strontium isotope studies of carbonates from soils, veins, eolian dust and Paleozoic basement sampled near Crater Flat, southwest of Yucca Mountain, provide evidence for the origins of...
A Formalism to Generate Probability Distributions for Performance-Assessment Modeling
A formalism is presented for generating probability distributions of parameters used in performance-assessment modeling. The formalism is used when data are either sparse or nonexistent....
