A Literature-Based Preliminary Characterization of Risks in the Nuclear Waste Management System
The objectives of this study were to 1) review the literature containing information on risks in the nuclear waste management system and 2) use this information to develop preliminary...

The Systems Integration Modeling System
The Systems Integration Modeling System (SIMS) is an analysis tool for the detailed evaluation of the structure and related performance of the Federal Waste Management System (FWMS) and...

Evaluating and Controlling the Characteristics of the Nuclear Waste in the FWMS Using Waste Stream Analysis Model
The Waste Stream Analysis (WSA) Model is used by the Department of Energy to model the time and location dependent properties of the nuclear waste stream in the Federal Waste Managements...

Systems Integration Operations/Logistics Model (SOLMOD)
SOLMOD is a discrete event simulation model written in FORTRAN 77 and operates in a VAX or PC environment. The model emulates the movement and interaction of equipment and radioactive...

A Systems Engineering Cost Analysis Capability for Use in Assessing Nuclear Waste Management System Cost Performance
The System Engineering Cost Analysis (SECA) capability has been developed by the System Integration Branch of the U.S. Department of Energy's Office of Civilian Radioactive...

The Coordination of System Representation and Operating Assumptions for System Studies in SIMS
Two projects at the Pacific Northwest Laboratory (PNL) have been devoted to development of the capability to provide descriptive details of the Federal Waste Management System (FWMS) and...

Method for Determining the Fuel Contribution to the Source Term in Trasnport Casks
A comprehensive source term characterization methodology has been developed for the determination of the fuel contribution to the potentially releasable radioactivity in spent fuel shipping...

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,...

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...

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...

Space Transportation Node: The Atrium Facility
During the next thirty years the infrastructure of space transportation is expected to expand to a system of advanced vehicles. A transportation node is an important link, as a vehicle...

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...

MALEO: Modular Assembly in Low Earth Orbit: An Alternate Strategy for Lunar Base Deployment
Modular Assembly in Low Earth Orbit (MALEO) is a new strategy for building an initial operational capability lunar habitation base. In this strategy, the lunar base components are brought...

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...

Unusual Spacecraft Materials
For particularly innovative space exploration missions, unusual requirements are levied on the structural components of the spacecraft. In many cases, the preferred solution is the utilization...

Motion Control of Space Structures
A new area of civil engineering is emerging as we begin to establish a permanent presence in space. The new area of civil engineering is the motion control of space structures. This paper...

Effects of Initial Conditions on Large Space Structures
Effects of initial conditions of axial deformation (length) and attitude (pitch) angle have been investigated on the subsequent orbital motion, attitude (librational) motion, and axial...
