Facility Interface Capability Assessment (FICA) Project
The U.S. Department of Energy-Office of Civilian Radioactive Waste Management (DOE-OCRWM) is sponsoring the Facility Interface Capability Assessment Project to determine current and potential...
Modeling of Coupled Heat-Mass-Stress Effects in Geologic Media
To investigate the importance of coupled hydraulic-thermal-mechanical processes for the potential nuclear waste storage repository at the Yucca Mountain, a computer code is being developed....
Hedonic Price Theory: Concept and Applications
Direct and indirect techniques are being used to estimate economic consequences of proximity to existing or proposed public facilities. The hedonic price theory, an indirect technique,...
Case System and Ancillary Equipment Maintenance
Per-shipment activities, incidental maintenance, repair, and routine maintenance for Federal Waste Management System (FWMS) casks and ancillary equipment and responsibility for those activities...
An Astronaut Positioning System for Space Station Assembly and Maintenance Support
Large space structures require special systems to support assembly, operations, and maintenance. These systems must be designed to support many tasks throughout the life of the space facility....
Automated Manufacturing in Platform-Based Orbital Systems (APROPOS)
As an example of an orbital manufacturing scenario, an automated orbital manufacturing system is designed for the production of turbine blades for high pressure turbines. The target here...
An Introduction to Pressurized Volumes in Space
Space habitation designers come from diverse backgrounds. As it is human nature to emphasize that which is familiar, habitat design is strongly influenced by the designer's...
Commercial Launch Facility Economic factors
Launch facility construction, maintenance and modification costs remain a largely invisible part of the cost of putting mass into orbit. The government can lease launch facilities to commercial...
Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....
The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...
Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...
Partial Gravity: Human Impacts on Facility Design
Partial gravity affects the body differently than earth gravity and microgravity environments. The main difference from earth gravity is human locomotion; while the main difference from...
Evaluation Plus History Equals Sewer Renovation
Sewers built in the 1920's were overflowing in the Fort Worth Zoo after moderate rain events. Data from A Sanitary Sewer Evaluation Survey (SSES), plus the Maintenance History...
Cost-Effective Maintenance and Replacement Scheduling
The paper discusses operations research approaches to scheduling maintenance on components of water resources infrastructure. Cost and reliability objectives are explicitly considered....
Probabilistic Basis for Managing Maintenance
The paper discusses a procedure based on component failure probabilities, consequences of failure, and risk associated with loss of system. Aging effect of structures and equipment on...
Models for Optimal Maintenance of Hydraulic Structures
Corrective maintenance includes the unscheduled repairs required to return a structure from a failed state to an operating or available state. Corrective maintenance is determined by the...
Probabilistic Analysis of Maintenance Options
Maintenance usually means service disruption, repair cost and loss of production. This is especially true for structures or components which provide basic infrastructure services, such...
Remote Infrared Thermal Sensing of Sewer Voids
The question addressed by this paper is how to detect unseen problem areas in sewer systems before they give way. At present, progressive sewer administrations may use crawl crews or television...
Rehabilitation of Rapidly Urbanizing Streams
DuPage County, Illinois is implementing a stream maintenance program with the purpose of restoring and preserving the hydraulic efficiency of its streams and drainageways. The program...
Key Environmental Development Issues
Those in the business community who may be affected by environmental factors include: buyers and sellers of businesses, existing facilities, and real property; their lenders, brokers,...
