Multipoint Grout Injection System. Innovative Technology Summary Report
At the Oak Ridge Reservation (ORR), radioactive waste contained in the 16 cylindrical Gunite and Associated Tanks (GAATs) must retrieved so the tanks can be closed. In many cases, removing the small amounts of sludge that remain in the tank after the bulk of the waste is retrieved is extremely costly and provides little benefit from site health and environmental standpoints. The Tanks Focus Area is working with ORR's M and I contractor (Bechtel-Jacobs), Oak Ridge National Laboratory, and Ground Environmental Services to demonstrate the application of multi-point-injection (MPI) grout emplacement technology for horizontal cylindrical tanks during a cold demonstration in FY99. GAAT TH-4 has been identified as the tank to be used for the hot demonstration in FY00. Evaluation efforts continue on the effect of slag on strength performance of the grout to be used in TH-4 tank closure. The site must find out what level of slag can be accommodated in the grout while maintaining strength performance requirements. Other efforts in support of the utilization of MPI TM technology in large-scale waste tanks will continue. Also, ORR is collaborating with SRS to evaluate the use this technology to support grouting of the Old Burial Ground tanks at SRS.
