Preliminary Conceptual Design Description of the Proposed DOE Store-Only Monitored Retrievable Storage (MRS) Facility
The Nuclear Waste Policy Act (NWPA) of 1982 required DOE to examine the options for the provision of long term spent fuel storage in monitored retrievable storage (MRS) facilities. Specifically,...
Ventilation and Construction Considerations for a High Level Nuclear Waste Repository
The storage of high level nuclear waste in an underground repository presents engineering problems in ventilation, construction methods and plan, and in proposed retrievability. Temperatures...
Requirements and Concept for an On-Orbit Construction Facility for Phase 1 Space Station Freedom
Future NASA plans for exploring the solar system and programs such as the Large Deployable Reflector and Pathfinder require in-space construction for their success. The technologies required...
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....
Telerobotic Capabilities for Space Station Operations
Over the past decade, the M.I.T. Space Systems Laboratory has accumulated an extensive data base on space operations typical of those planned for the Space Station, based on integrated...
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,...
Space Station Freedom Attached Payloads and Commercialization
The Space Station Freedom (SSF) accommodates a class of payloads called external attached payloads. These payloads are attached to the main truss of Space Station Freedom through the use...
Incident Solar Flux at Fixed Orientations
Optimal orientations are computed to maximize or minimize the incident solar flux onto surfaces on spacecraft at fixed attitudes. This analysis was motivated by a potential need to optimize...
Space Debris?A Design Consideration
With the increased use of space by manned or unmanned missions, it has become necessary to include yet another parameter in the design of spacecraft, namely, the effect of a probable impact...
Man-Made Debris Environment Characterization for Spacecraft Vulnerability Assessment
An issue of growing importance in the study of orbital debris is the need to understand the consequence of impact on a space structure. In this paper, a technique is developed to analyze...
Clearing Space Debris Using Energetic Materials
Space debris is growing at an alarming rate. It consists not only of old, unusable payloads but also aluminum oxide combustion products of various space delivery systems and small fragments...
