Recent hydrofracture operations at Oak Ridge National Laboratory
The hydrofracture process is currently being used at Oak Ridge National Laboratory (ORNL) for the permanent disposal of locally generated radioactive waste solutions and slurries. In this process, the waste solution or slurry is mixed with a blend of cement and other solid additives; the resulting grout is then injected into an impermeable shale formation at a depth of 200 to 300 m (700 to 1000 ft). The grout sets a few hours after completion of the injection, fixing the radioactive waste in the shale formation. A new facility was built in 1980-1982 at a site adjacent to the original facility. Between June 1982 and January 1984, more than eight million liters (2.2 million gal) of waste containing over 750,000 Ci were mixed with a blend of solids and injected. Various operating problems were experienced and solved. 6 references, 6 figures, 1 table.
