Estimate of the Source Term for a Repository Surface Facility From the Routine Processing of Spent Fuel
The potential for release of radioactive material from the proposed handling and processing of spent nuclear fuel in a surface facility for a geologic repository was evaluated. The potential...

Effect of Minor Actinide Removal From Fission Products Before Vitrification on the Radiological Impact of a High Level Waste Deep Repository
The topic of this work is to assess the effect of minor actinide (Cm, Am, Np) removal from fission products before vitrification on the radiological impact of a vitrified waste geological...

The Source Term for HLW Disposal in the European Communities' R&D Programme
During the last five years, the EC's research programme on radioactive waste has focused much of its investigation in the field of HLW management on the source term for geologic...

Computed Distributions of Residual Shaft Drilling and Drift Construction Water in the Exploratory Facilities at Yucca Mountain, Nevada
The Yucca Mountain Project is studying the feasibility of constructing a high-level nuclear waste repository at Yucca Mountain in southwest Nevada. One activity of site characterization...

Multi-Dimensional Modeling of Unsaturated Flow in the Vicinity of Exploratory Shafts and Fault Zones at Yucca Mountain, Nevada
Modeling studies were conducted to determine the potential effects of exploratory shafts on moisture distribution in the vicinity of an exploratory shaft facility, and the potential for...

Status of Site Investigations for Spent Fuel Repository in Finland
TVO's site programme aims at selection of a repository site for spent fuel by the end of 2000. A repository is planned to be constructed in the 2010's and commissioned...

Analysis of Requirements for Data and Information for the Management of Spent Nuclear Fuel Designated for Disposal in a Mined Geologic Repository
Official documents and relevant published papers were reviewed to determine what information on spent fuel will be needed by the Department of Energy (DOE) in order for it to meet its...

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...

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,...

High Level Waste Management at Sellafield
Reprocessing of irradiated nuclear fuel has been carried out at Sellafield since 1952, when reprocessing of fuel from the original UK air-cooled reactors began. In 1964 a second reprocessing...

Influence of High Burn Up Nuclear Fuel and MOX on the High Level Reprocessing Waste Management
This paper compares characteristics of high level waste issued from the reprocessing of high burn up fuel (HTC) and mixed oxide (U-Pu)O2 fuel (MOX)...

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...

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,...

The Role of the U.S. Nuclear Waste Technical Review Board
The Nuclear Waste Technical Review Board is a new independent governmental establishment with in the Executive Branch created in December 1987 when Congress enacted the Nuclear Waste Policy...

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...

Global Problems: Implementing Mission to Planet Earth
Serious global environmental problems are facing our generation on Earth. The decrease in ozone concentrations and the greenhouse effect have implications for all life forms on the planet....

Composting for Lunar Agriculture
Alternative technologies for the microbially mediated biological oxidative transformation (composting) of human wastes and other organic wastes are presented. Batch mode and continuous...

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...

Challenges and Opportunities in the '90s and Beyond?A U.S. Army Corps of Engineer's Perspective
In the foreseeable future, water resources expenditures will probably be dominated by environmental/water quality concerns. Strong focus is coming to bear on the state of repair, rehabilitation...
