Disposal of Defense Spent Fuel and HLW from the Idaho Chemical Processing Plant
Acidic high-level radioactive waste (HLW) resulting from fuel reprocessing at the Idaho Chemical Processing Plant (ICPP) for the U. S. Department of Energy (DOE) has been solidified to...

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...

Simulated Hanford Waste: A Study of Physical Properties, Gas Retention, and Gas Generation
This study helps to establish the physical and chemical processes responsible for the generation and retention of gases within high-level waste contained in Tank 101-SY on the Hanford...

Evaluation of Neutron Emission from Vitrified HLW Compositions
Neutron radiological hazards from vitrified HLW are important for handling and transportation - especially if the concept of separate storage of concentrated transuranics is adopted, as...

Treatment of Non Fuel Bearing Scrap
Problems encountered with the processing of irradiated non fuel bearing components (NFBC) during several rod consolidation demonstration programs identified the need to conduct further...

Non-Fuel Bearing Hardward Melting Technology
Battelle has developed a portable hardware melter concept that would allow spent fuel rod consolidation operations at commercial nuclear power plants to provide significantly more storage...

Recent Developments in Stochastic Modeling and Upscaling of Hydrologic Properties in Tuff
A set of detailed geostatistical simulations of porosity has been produced for a layered stratigraphic sequence of welded and non-welded volcanic tuffs at Yucca Mountain, Nevada. The simulations...

Stochastic Simulation of Mass Transport in Heterogeneous Formations Using Hard and Soft Conductivity Data
The mass transport in a synthetic 2-D heterogeneous formation is simulated through the Monte-Carlo method using continuum approach. The simulated hydraulic conductivity field are generated...

Use of Coupled Geochemical and Transport Calculations for Nuclear Waste Problems
The dissolution and migration of radionuclides from a final repository for radioactive waste is complex chemically. The dissolution and release rates depend on the chemistry and on advective...

Surface Complexation Model Prediction of Np and Pu Distribution Coefficients
Robust estimates of radionuclide sorption coefficients (K_d) are needed to estimate radionuclide retardation during ground-water transport from a...

??⁴U/??⁸U as a Ground-Water Tracer, SW Nevada-SE California
The ²³⁴U/²³⁸U ratio of uranium in oxidizing ground waters is potentially an excellent ground-water tracer...

The Independent Cost Estimating Process
The United States Department of Energy (DOE) requires that an Independent Cost Estimate (ICE) be prepared for all Major Systems Acquisitions (MSAs); that is, projects or programs expected...

Evaluation of Borosilicate Glass as a High-Level Radioactive Waste Form
The choice of a borosilicate glass as a high-level nuclear waste form is evaluated base on observations of natural and artifical glass hydration and reaction, experimental results of glass...

The Effect of Gamma Irradiation on the Volatility and Redox State of Simulated DWPF High-Level Nuclear Waste Glasses
Gamma-induced volatility of simulated DWPF high-level nuclear waste glasses is highly dependent upon the redox state of the glass. For oxidized glasses with an Fe²⁺/(Fe²⁺...

Hanford Ferrocyanide Reactivity: Effects of Other Tank Constituents
In this study simulated wastes were used to determine the effect of potential waste constituents on the reactivity and explosivity of Hanford ferrocyanide-bearing wastes. Test results...

Lead Isotopic Composition of Paleozoic and Late Proterozoic Marine Carbonate Rocks in the Vicinity of Yucca Mountain, Nevada
Paleozoic and Late Proterozoic marine carbonate rocks (limestones, dolomites, and their metamorphic equivalents) cropping out in the vicinity of Yucca Mountain contain lead with an isotopic...

Ecological Risk Assessment of Proposed Deep Geologic Disposal of High-Level Nuclear Waste in Canada
Using population dynamic models of moose and brook trout, and assuming topographic, hydrographic and other habitat features typical of the Canadian Shield in Ontario, we have estimated...

Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...

Stochastic Modelling of Groundwater Flow at the WIPP Site
A stochastic approach to modelling the groundwater flow in the vicinity of the WIPP site in New Mexico is described. A geostatistical model of the transmissivity of the Culebra dolomite...
