EG G sampling program results FY 1989

Description: Thirty-three waste drums were returned to Rocky Flats in support of EG G Idaho's quality control program for the Stored Waste Examination Pilot Plant. The drums were opened and examined in the size reduction facility at the Rocky Flats Plant. Contents of each drum were consistent with the Item Description Codes; however, four sludge drums and one combustible drum contained free liquids. These five drums failed to meet the Waste Isolation Pilot Plant and the Department of Transporation criteria.… more

Icelandic basaltic geothermal field: A natural analog for nuclear waste isolation in basalt

Description: Analog studies of Icelandic geothermal fields have shown that the design of nuclear waste repositories in basalt can benefit by comparison to the data base already available from the development of these geothermal fields. A high degree of similarity exists between these two systems: their petrology, groundwater geochemistry, mineral solubilities, hydrologic parameters, temperature ranges, water-rock redox equilibria, hydrothermal pH values, and secondary mineralogies all show considerable over… more

Use of a Stochastic Model to Evaluate Uncertainty in a Performance Assessment at the Savannah River Site - 8120

Description: A significant effort has recently been initiated to address probabilistic issues within radiological Performance Assessments (PA's) conducted at the Savannah River Site (SRS). This effort is considered to be part of a continual process, as is the program of PA analysis and maintenance across the Department of Energy (DOE) complex. At SRS, findings in the initial probabilistic analysis of the Slit Trenches in the E-Area PA were built upon and improved in the later development of the probabilisti… more

Status report on the fluidized bed incineration system for U. S. Department of Energy, Defense Waste, January--June 1977

Description: A fluidized-bed incineration facility has been designed for installation at the Rocky Flats Plant to develop and demonstrate the process for the combustion of transuranic waste. The unit capacity will be about 82 kg/hr of combustible waste. The combustion process will utilize in situ neutralization of acid gases generated in the process. The equipment design is based on data generated on a pilot scale unit, and represents a scale-up factor of nine. Building modifications are complete and equipm… more

MFT homogeneity study at TNX: Final report on the low weight percent solids concentration

Description: A statistical design and analysis of both elemental analyses and weight percent solids analyses data was utilized to evaluate the MFT homogeneity at low heel levels and low agitator speed at both high and low solids feed concentrations. The homogeneity was also evaluated at both low and high agitator speed at the 6000+ gallons static level. The dynamic level portion of the test simulated feeding the Melter from the MFT to evaluate the uniformity of the solids slurry composition (Frit-PHA-Sludge… more

FRACTIONAL CRYSTALLIZATION OF HANFORD SINGLE SHELL TANK (SST) WASTES A MODELING APPROACH

Description: The Hanford site has 149 underground single-shell tanks (SST) storing mostly soluble, multi-salt, mixed wastes resulting from Cold War era weapons material production. These wastes must be retrieved and the salts immobilized before the tanks can be closed to comply with an overall site closure consent order entered into by the U.S. Department of Energy (DOE), the Environmental Protection Agency, and Washington State. Water will be used to retrieve the wastes and the resulting solution will be p… more

Concrete Support Design for Miscellaneous Esf Utilities

Description: The purpose and objective of this analysis is to design concrete supports for the miscellaneous utility equipment used at the Exploratory Studies Facility (ESF). Two utility systems are analyzed: (1) the surface collection tanks of the Waste Water System, and (2) the chemical tracer mixing and storage tanks of the Non-Potable Water System. This analysis satisfies design recommended in the Title III Evaluation Reports for the Subsurface Fire Water System and Subsurface Portion of the Non-Potable… more

WATER DIVERSION MODEL

Description: The distribution of seepage in the proposed repository will be highly variable due in part to variations in the spatial distribution of percolations. The performance of the drip shield and the backfill system may divert the water flux around the waste packages to the invert. Diversion will occur along the drift surface, within the backfill, at the drip shield, and at the Waste Package (WP) surface, even after the drip shield and WP have been breached by corrosion. The purpose and objective of t… more

Determination of performance criteria for high-level solidified nuclear waste from the commercial nuclear fuel cycle: a probabilistic safety analysis

Description: To minimize the radiological risk from the operation of a waste management system for the safe disposal of high-level waste, performance characteristics of the solidified waste form must be specified. The minimum waste form characteristics that must be specified are the radionuclide volatilization fraction, airborne particulate dispersion fraction, and the aqueous dissolution characteristics. The results indicate that the pre-emplacement environs are more limiting in establishing the waste form… more
