Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...
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...
Spray and Ice Measurement Instrumentation for Ships
Bow slamming is the primary water delivery mechanism for ship superstructure icing. Spray flux is largely dependent upon hull dynamics, and cannot be computed numerically with current...
The USACRREL Underwater Frazil Ice Detector
A modified underwater frazil ice detector has been developed at USACRREL. This detector, which operates remotely, can automatically start deicing procedures and alert operators to the...
Condition Assessment Experience with Silos and Bunkers
This paper presents a methodology for condition assessment of coal silos and bunkers for retrofitting projects. Some typical problems such as corrosion, erosion, vibrations and buckling...
Optimization Models for Acid Rain Control
A series of related optimization formulations are presented for developing and analyzing acid rain control strategies. These models span a wide array of approaches and reflect a similarly...
Automation of Union Electric's Hydro-Power Plants
Union Electric Company is spending twelve million dollars on Electronic Control and Monitoring equipment at two of their hydro-electric plants (a total of twenty-seven generating units)...
Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...
Development of the GA-4 and GA-9 Legal Weight Truck Spent Fuel Shipping Casks
General Atomics (GA) is developing two legal-weight-truck spent-fuel shipping casks for transporting commercial reactor spent fuel. The GA-4 pressurized-water-reactor (PWR) and the GA-9...
Radiocolloid Transport in Saturated and Unsaturated Fractures
Studies have shown that radionuclides and toxic materials can attach to colloidal particles in groundwater or are themselves colloids. Since these contaminated particles can migrate several...
Design Control Process Requirements for Geologic Repository Operations Area Design
This paper outlines U.S. Nuclear Regulatory Commission's (NRC's) key regulations applicable to U.S. Department of Energy's (DOE's) design...
Design Control Overview fot the Yucca Mountain Site Characterization Project Exploratory Shaft Facility
This paper presents an overview of the design control process used for the Exploratory Shaft Facility (ESF) at Yucca Mountain. Design and design control is a complex, often iterative,...
Application of QA Grading to Yucca Mountain Site Characterization Project Items and Activities
Grading is the act of selecting the quality assurance (QA) measures necessary to develop and maintain confidence in the quality of an item or activity. The list of QA measures from which...
Controlling the Description of a High-Level Radioactive Waste Isolation System
Control of large, complex, regulation-driven programs using traditional management methods has not been wholly effective. What is needed is a rigorous yet flexible method that is amenable...
Strain Distribution in Fault Zones and Fluid Flow
Field and laboratory studies have shown that mechanical shearing in fault zones produces a repeatable fabric that changes with increasing shear strain. In the brittle field of mechanical...
Fractal Characteristics of Fracture Roughness and Aperture Data
In this study mathematical expressions are developed for the characteristics of apertures between rough surfaces. It shown that the correlation between the opposite surfaces influences...
Assessment of Fracture-Sampling Techniques for Laboratory Tests on Core
As part of the site characterization work to be done at Yucca Mountain in Nye County, Nevada, a candidate site for the first mined-geologic repository for high-level nuclear waste, laboratory...
Conceptual Design Study of Geological Disposal System of High-Level Waste
Conceptual design study of geological disposal system for HLW was carried out taking into account geological environment in Japan, in order to provide disposal concepts for integrated...
Product Quality and Process Control in the Windscale Vitrification Plant
The Windscale Vitrification Plant (WVP) is owned and operated by British Nuclear Fuels (BNFL) at the Sellafield Site in England. The purpose of the facility is to condition the high level...
Effect of Material Heterogeneities on Flow Through Porous Media
Modeling studies were conducted to determine the effects of material heterogeneities on the flow of water through rock. Multiple numerical calculations were made using random variations...
