Disposal of liquid radioactive wastes through wells or shafts

Description: This report describes disposal of liquids and, in some cases, suitable solids and/or entrapped gases, through: (1) well injection into deep permeable strata, bounded by impermeable layers; (2) grout injection into an impermeable host rock, forming fractures in which the waste solidifies; and (3) slurrying into excavated subsurface cavities. Radioactive materials are presently being disposed of worldwide using all three techniques. However, it would appear that if the techniques were verified as… more

Solubility of krypton in hydrofracture grout at elevated pressures

Description: The solubilities of krypton in water, simulated waste solution, and simulated grout at about 25/sup 0/C and to pressures of 150 atm have been determined. The results of these studies show that preliminary calculations of krypton solubility based on the aqueous component of the hydrofracture grout were overly pessimistic. The volume of noble gas generated annually by the reference reprocessing plant would be soluble in the annual hydrofracture grout injection at ORNL at about 10 atm. The amount … more

A microwave interferometer to measure transient properties

Description: A simple K-band microwave interferometer has been developed at the Los Alamos National Laboratory to measure various transient properties in both energetic (high explosive) and passive (grout and Teflon) materials. The interferometer measures the position as a function of time of either a dielectric discontinuity, i.e., a shock front, or the position as a function of time of a conducting surface such as the detonation wave in a high explosive. By embedding a reflector in a dielectric material, … more

Formulation and durability of tailored cementitious hosts applied to TRU waste generated at the Rocky Flats Plant

Description: This paper discusses the development of cementitious grout formulations at the Oak Ridge National Laboratory which immobilize up to 50% of Rocky Flats Building 374 startup TRU waste. Trial grout mixes were tested in order to minimize the water content and maximize the waste loading. The effects of water reducers and set regulators on these trial mixes were also examined. Durability and physical-property measurements were performed on formulations which are compatible with standard processing eq… more

Strontium leachability of hydrofracture grouts for sludge-slurries

Description: A series of experiments to determine the strontium leachability of cement-based sludge-slurry hydrofracture grouts is summarized. The hydrofracture process has been used at ORNL since 1966 for the routine disposal of intermediate-level waste (ILW) solutions. In this process, cement and other additives are mixed with a waste stream to form grout, which is then injected into a shale bed at a pressure sufficient to cause fracturing along the horizontal bedding planes. This injected grout soon hard… more
