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...
Incorporation of Reprocessing Raffinates and High Level Solids in Cement
Reprocessing highly enriched uranium fuel from UKAEA Materials Testing Reactors produces highly active aqueous raffinate. This is currently stored. The UK strategy is for raffinate immobilisation,...
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,...
Fabrication and Closure Development of Nuclear Waste Containers for Storage at the Yucca Mountain, Nevada Repository
U.S. Congress and the President have determined that the Yucca Mountain site in Nevada is to be characterized to determine its suitability for construction of the first U.S. high-level...
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...
The Expected Condition of Spent LWR Fuel on Delivery to a Repository
The condition of spent fuel on delivery to a repository is affected by its service in the reactor and by the postirradiation activities including wet and dry storage; fuel examination,...
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...
Post-MECO Propulsion System Requirements for Placement of an STS External Tank in Low Earth Orbit
This paper discusses the findings of a series of computer simulations carried out at the National Institute of Standards and Technology to investigate the requirements for powered flight...
Lunar Base Elements Designed for Robotic Operations
Equipment concepts developed for a study of robotic lunar surface operations are presented. The concepts were evolved together with a consistent robotic buildup and operations scenario;...
Preliminary Assessment of the Power Requirements of a Manned Rover for Mars Missions
This paper presents the results of a preliminary study to determine the total mass and power requirements of a Manned Mars Rover. The primary power for the Rover is provided by a Nuclear...
Lunar Base Power Requirements, Options & Growth
A preliminary study of lunar base scenarios and associated power requirements has recently been completed. Minimum power levels of 50-100 kW are required for 'science-only'...
Designed Experiments: An Interdisciplinary Approach to Space Education
The challenge of space is forcing engineering faculties to re-examine their roles in preparing college graduates to contribute to the space exploration and colonization effort. One of...
Space Power Systems?Radiation: Energy Conversion
Pair production is a way to change a photon, a gamma particle, into matter or energy. It is found that if a photon of energy greater than 1.02 MeV strikes a foil containing a large number...
Wastewater Balance for Storage Pond at Land Treatment Site
Land application is an established method for treating municipal wastewater in the United States. Most land application operations include on-site facilities to store wastewater during...
Using Corps of Engineers' Reservoirs for Water Supply
This paper provides an historical overview of the Corps of Engineers (COE) authority in the water supply arena and discusses the methodologies and procedures used to reallocate storage...
Site Specific Hydrological Model for Permaculture Application
