Wind Power in Antarctica?Case Histories of the North Wind HR3 Wind Turbine
The combination of extreme weather conditons and remoteness of the Antarctic sites makes them even better suited for wind turbine installations since the alternative power sources are...

The Processing of Simulated High-Level Radioactive Waste Sludges Containing Nitrites and Mercury
The reaction of formic acid with simulated alkaline sludge containing mercury and nitrite was studied in an engineering-scale facility. Quantification of offgas production was performed,...

Properties of Solidified HLW and Their Changes Under Storage and Disposal Conditions
The paper gives the results of the studies of the properties of different solidified high level waste (HLW) - vitreous (phosphate and borosilicate) composites as well as glass ceramics...

Field Investigations for Seismic Effects on Mechanical and Geohydrologic Response of Underground Structures in Jointed Rock
An exploratory Seismic Rock Mechanics research program has been initiated by the U.S. Nuclear Regulatory Commission at the Center for Nuclear Waste Regulatory Analyses (CNWRA) to study...

Variation of Permeability with Temperature in Fractured Topopah Spring Tuff Samples
Fractures will play an important role in the near-field hydrology of a nuclear-waste package in a mined repository. Our previous studies showed that the water permeability of fractured...

Potential ?⁴CO₂ Releases from Spent Fuel Containers at Yucca Mountain
The potential release of gaseous ¹⁴CO₂ from small perforations in spent fuel containers has been evaluated...

Cask Systems Development Program Seal Technology
General design or test performance requirements for radioactive materials (RAM) packages are specified in Title 10 of the U.S. Code of Federal Regulations Part 71 (10 CFR 71). Seals that...

General Circulation Models: Applications for Nuclear Waste Repositories
Numerical models have long been used to relate causal and response functions in the natural environment. Some 20 years ago, one-dimensional, multi-causal models of earth temperature evolved,...

Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...

The Constructive Use of Heat in an Unsaturated Tuff Repository
By designing the engineered barrier system in an unsaturated tuff repository to constructively use heat, the waste containers can be kept dry for hundreds of years. Without water, the...

COMBAT.PC; a New Windows-Based Tool for Three-Dimensional Dynamic Analysis of Multi-storied Building Structures
By some accounts, analytical capability without the power of visualization is little productive; visualization is the tool that will turn computational power into practical results. COMBAT.PC...

Effect of Camera Geometry on Thermographs for Pavement Crack Detection
The research focused on the effects of camera heights and tilt angles on the ability to detect cracks in thermographs obtained with an infrared camera. Results indicate that differences...

Infrared Thermography Based Pipeline Leak Detection
Computerized Infrared Thermographic pipeline inspection is now a refined and reliable process having been thoroughly proven to be an accurate, cost effective, and efficient technology...

Remote Sensing for Seismic Hazard Assessment of a Proposed Nuclear Power Station, North Wales, UK
During the seismic hazard assessment for a proposed nuclear power station in North Wales, UK, a remote sensing study was carried out in conjunction with other, wide-ranging geological...

Estimating Power Plant Cooling Water Demand
The Fayette Power Project (FPP) includes three generation units, with more than 1,500 megawatts of generating capacity, supplying electricity to more than a million Central Texans. The...

p-Version Three Dimensional Solid Element for Heat Conduction
This paper presents a finite element formulation for a three dimensional twenty-seven node hierarchical solid element for heat condition where the element temperature approximation can...

Dynanmic Stability and Seismic Response of Damped Beams in the Presence of Follower Forces
The dynamic stability and the seismic response of general beams are examined, by discretizing the structure to a set of rigid bars, linked together by means of elastic constraints (Cells...

Effects on Seismic Spatial Variations to Suspension Bridge Responses
The dynamic soil-structure interaction effects and spatial variations of a seismic motion seem to have significant contributions on the response evaluation of a long span suspension bridge....

Comparative Time Domain Analysis of Some Available Analytical and Empirical Expressions for the Spatial Variability of Seismic Ground Motions
Simulations in space and time based on models for the spatial variability of seismic ground motions are generated. Displacement time histories are simulated through the spectral representation...

Thermal Effects in a Transient Study of Fracture
Studies, e.g. Zehnder and Rosakis (1989), indicate that fracture is associated with temperature rises in inelastic zones near the crack edge. To gain more insight into this phenomenon,...
