This document concerns the shale fracturing injections at Oak Ridge National Laboratory, 1977-1979 Series. Intermediate-level waste solution generated at ORNL is periodically mixed with a cement-base blend of dry solids and injected into an impermeable shale formation at an approximate depth of 240 m (800 ft). The grout mix sets shortly after the injection, permanently fixing the radionuclides in the shale formation. A series of four injections of intermediate-level waste solution was made between 1977 and 1979. A total of 1.2 million l (314,000 gal) of waste solution containing 81,780 Ci of radionuclides was injected. This report is an account of this injection series - preparations, injections, results, and conclusions. The volumes and activities that were injected were summarized. Logs of the observation wells indicated that all grout sheets were within the disposal zone. Figures and tables are included.
