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...

Design Program for Gravity Sanitary Sewers
The Gravity Sewer Design Program Version 2.1 M (GSDP2M) performs the hydraulic design for a conventional gravity sanitary sewer network. GSDP2M is written in standard Fortran 77 for batch...

The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...

Network Modeling in a Water System with Ferrous Deposits
This paper presents the experiences and results of a network modeling study. A model for the University of Idaho water supply system was developed and verified to the extent possible with...

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,...

Atomistic Simulation and Visualization of Thermal Disorder in a Crystalline Ice
The process of thermal disorder in crystalline ice has been simulated using a molecular dynamics model. The thermal disorder is induced by raising the temperature of the system. The molecular...

Factors Affecting the Incremental Stiffness of Particle Assemblies
A simple numerical experiment was performed on an assembly of densely packed spheres in order to investigate the factors that affect an assembly's incremental stiffness. The...

Scale Effects in Cone Penetration Tests
A field testing program was undertaken to examine the existence of scale effects between a miniature 1.27 cm² and 15 cm²...

Sea Water Environmental Remote Sensing Application on Daya Bay Nuclear Power Station
Owing to its extensive and complete characterization, remote sensing investigations have a special ability to analyze seawater environments and to monitor pollution at coastal nuclear...
