A major effort of site characterization activities at Yucca Mountain, Nevada, a site being studied by the U.S. Department of Energy (DOE) as a potential repository of high-level radioactive...
Modelling Colloidal Transport of Radionuclides Through Porous Media
General acknowledgement of the potential role of colloids in enhancing radionuclide transport has prompted the preliminary development of a mechanistic colloid transport model as part...
Are Colloids Important for Transport Rate Assessment of Radionuclides? A Microscopic Modeling Approach
Understanding the transport phenomena of radionuclides migrating through weakly-permeable rocks forms an essential part of far-field safety assessment studies. Colloidal matter can be...
Experience in Modeling for Environmental Physics and Biogeochemistry
This report is a short review of the author's personal experience on phys.-math. and system-logical modeling of migration and transport processes (MTP) of radionuclides, trace-elements...
The Analysis of Repository-Heat-Driven Hydrothermal Flow at Yucca Mountain
To safely and permanently store high-level nuclear waste, the potential Yucca Mountain repository site must mitigate the release and transport of radionuclides for tens of thousands of...
Spent Fuel Assembly Source Term Sensitivity Parameters: SAND92-2113C TTC-1225
Containment of cask contents by a transport cask in a function of the cask body, one or more closure lids, and various bolting, hardware, and seals associated with the cavity closure and...
Inference of Moisture Content in Unsaturated Media Using Ultrasonics
This study focuses on the ability of commercial ulltrasonics equipment to determine the moisture content in unsaturated media. We are interested in the possible application of this technology...
Radionuclide Transport in Fractured Media
Until recently, the classical advective-dispersive transport equation was considered to be an adequate model for describing the motion of a solute (e.g. radionuclides) in porous and fractured...
An Object Oriented Relational Database for Assessing Radioactive Material Transport
EnviroView is an object oriented relational database used for inventory control and monitoring locations of radioactive and toxic materials. Visual images of local sites, building locations,...
Plutonium and Minor Actinide Transmutation by Long Irradiation in LWR
An investigation was made on the conceptual possibility of burning in a thermal reactor MOX fuel together with special pins containing plutonium, minor actinides and long-lived fission...
Remote Spent Fuel Handling in France at the La Hague Cask Unloading Facility
French policy for the back end of fuel cycle is based on spent fuel reprocessing. Irradiated spent fuels are transferred in casks from the nuclear reactors to the reprocessing plant where...
