Formic Acid Requirement for Savannah River Site Defense Waste Processing Facility Melter Feed Preparation (U)
The Westinghouse Savannah River Company (WSRC) will vitrify the high-level radioactive waste into a borosilicate glass wasteform using a slurry-fed, joule-heated melter. Formic acid is...
Removal of Dissolved and Suspended Radionuclides from HWVP Liquid Wastes
It was determined during Preliminary Design of the Hanford Waste Vitrification Plant that certain intermediate process liquid waste streams should be decontaminated in a way that would...
Characterization of High Radioactive Waste in a Reprocessing Plant Using Passive and Active Neutronic Methods
In the new UP3 reprocessing plant at LA HAGUE, drums containing hulls and endpieces are produced at the end of the shearing and dissolution shop. The determination of residual fuel masses...
Product Quality and Process Control in the Windscale Vitrification Plant
The Windscale Vitrification Plant (WVP) is owned and operated by British Nuclear Fuels (BNFL) at the Sellafield Site in England. The purpose of the facility is to condition the high level...
The Processing of Simulated High-Level Radioactive Waste Sludges Containing Nitrites and Mercury
The reaction of formic acid with simulated alkaline sludge containing mercury and nitrite was studied in an engineering-scale facility. Quantification of offgas production was performed,...
Mineralogic Alteration History and Paleohydrology at Yucca Mountain, Nevada
The importance of paleohydrology to the Yucca Mountain Site Characterization Project derives from the role water will play in radioactive-waste repository performance. Changes in hydrologic...
Lubrication Theory Analysis of the Permeability of Rough-Walled Fractures
Lubrication theory is used to study the permeability of rough-walled rock fractures. Two idealized models of a fracture, in which the roughness follows a sinusoidal or a sawtooth variation,...
Modelling of Hydro-Thermo-Mechanical Effects in a Fracture Intersecting a Nuclear Waste Deposition Hole
The groundwater flow in a vertical fracture intersecting a hypothetical nuclear waste deposition hole was examined. After excavation and emplacement of the nuclear waste canister, the...
Microwave Measurements of the Water Content of Bentonite
The theory of operation of microwave coaxial resonators is described. Sample preparation and the application of resonator techniques to the measurement of the permittivity (dielectric...
Early Deployment of the MRS?The Modular Vault Dry Store
The Nuclear Waste Policy Amendments Act of 1987 (NWPAA) authorized the Department of Energy to site, construct, and operate Monitored Retrievable Storage. The Modular Vault Dry Store is...
Design and Operation of a Monitored Retrievable Storage Facility Using NUHOMS? Technology
The NUHOMS dry storage system for spent fuel is now in use at two Independent Spent Fuel Storage Installations (ISFSIs) and a third is under construction. This system can be used for economical...
Disposal of Vitrified Waste in an Unsaturated Environment
An experimental program is described wherein the effect of important independent variables on glass reaction under conditions that may exist for unsaturated storage is examined. The effect...
Effect of HNO3-Cerium(IV) Decontamination on Stainless Steel Canister Materials
Stainless steel canisters will be filled with vitrified radioactive waste at the West Valley Demonstration Project (WVDP), West Valley, NY. After they are filled, the sealed canisters...
Mechanistic Interpretation of Glass Reaction: Input to Kinetic Model Development
Actinide-doped SRL 165 type glass was reacted in J-13 groundwater at 90?C for times up to 278 days. The reaction was characterized by both solution and solid analyses. The glass was seen...
Exclusion of Foreign Materials from the Savannah River Site (SRS) Canistered Waste Forms: Characterization of the Gas within the Free Volume
