“…After about four injections, the bottom of the well was plugged and a new slot cut in the casing about 3 to 5 m above the old slot. The surrounding shale formation was fractured at this new depth by water-pressurizing the well until a sudden drop in pressure signals the creation of a fracture (Weeren, 1979). Approximately 567.75 m 3 (150 000 gal) of grout could be injected each time at a Fig.…”

“…A test grout injection was made, followed by a water test injection (Sun, 1980). The new facility wi M be designed to handle higher activity wastes (up to 8 Ci/f) and the sludges that have accumulated at ORNL in the waste storage tanks over the past 35 years (which will have 90 Sr as the main contaminant) (Sun, 1980;Weeren, 1979;* ERDA-1553).…”

“…Occasional operational problems have been ex¬ perienced at ORNL, and are described in Weeren, 1979. The new facility at ORNL will use thicker walls for better shielding, and the cells will have stainless steel liners. Thus, with proper construction procedures, fairly high level beta-gamma wastes can be handled.…”

“…Tests at ORNL indicate low leach rates for the grout material (Weeren, 1979;Sun, 1980) Thus, if ground water contacts the grout sheet, there should be little mobilization of the radionuclides in the grout.…”

Disposal of liquid radioactive wastes through wells or shafts

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 posing minimum hazards to the environment and suitable site-specific host rock were identified, these disposal techniques could be more widely used. • M.
