Development of a CRUD Particle Size Distribution and Its Effect on Cask Source Term and Containment Analyses
Spent pressurized-water reactor (PWR) and boiling-water reactor (BWR) fuel rods from three reactors were examined by hot cell periscope, energy dispersive x-ray analysis, and scanning...
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...
Fluid Line Deployment and Repair for Space Station
Deployment of the utility system for providing services to the NASA Space Station Freedom provides a unique challenge in design and material technology. The system must be lightweight,...
A Space Station Trash Recovery and Recycling System
The quantity of trash produced on the Space Station during its lifetime will be substantial and will include useful waste materials. Given the high cost of transportation to orbit, it...
Application of Automation and Robotics to Lunar Surface Human Exploration Operations
Major results of a study (RLSO, 89) applying automation and robotics to lunar surface base buildup and operations concepts are reported. The study developed a reference base scenario with...
A Robotics Testbed for In-Space Assembly Tasks
The operations testbed of the Center for Space Construction at the University of Colorado is described. This testbed serves as a centralized testing environment for interdisciplinary research...
Wave Propagation in Hyper-Structures
The concept of hyperelement was introduced by E. Kausel and J.M. Roesset, 1977 in connection with the derivation of the dynamic stiffness matrix for layered continuum problems involving...
Biosphere II: Closed Ecological Systems Engineering
This paper provides a general description of the Biosphere II project - a 3.15 acre materially closed ecological system containing tropical rainforest, savannah, marsh, marine, desert,...
Conceptual Design for a Lunar-Base CELSS
Future human exploration is key to the United States National Space Policy goal of maintaining a world leadership position in space. In the past, spacecraft life support systems have used...
Investigation of HVAC Systems in Low Gravity Application
This paper has been developed to identify and summarize the principal areas of investigation necessary to design and install functional HVAC systems in low gravity applications. These...
Fluid Behavior Considerations for Waste Management in Low-Gravity Environments
Design of waste recycling systems for spacecraft requires a knowledge of fluid behavior in microgravity. As gravity is reduced, phenomena usually ignored in the One-G environment of earth...
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...
Considerations for the Development of a Commercial Spaceport
Several states and countries are currently reviewing the feasibility of developing a commercial spaceport in their homeland. United Engineers & Constructors Inc. completed an extensive...
