In situ grouting for improved confinement of buried TRU (transuranic) waste at the Idaho National Engineering Laboratory

Conference ·
OSTI ID:6302486
In situ grouting was experimentally examined as an improved confinement technique for buried transuranic (TRU) waste in a simulated waste trench at the Idaho National Engineering Laboratory (INEL). Prior to 1970, the INEL Radioactive Waste Management Complex (RWMC) served as a disposal site for defense-generated TRU waste. Between 1953 and 1970, approximately 56,000 m/sup 3/ of TRU waste were buried in shallow-land-filled trenches. As part of the Department of Energy's (DOE's) charter for managing the TRU waste, improved confinement techniques are being examined as a long-term management alternative. The object of the INEL in situ grouting study was to examine the capability of the in situ grouting technique to reduce voids in the waste and to hydrologically isolate the waste. To be considered a successful candidate for long-term confinement of the TRU waste, the acceptance criterion was that the grouted trench have a hydraulic conductivity no more than 1 /times/ 10/sup /minus/8/ cm/s, which is 100 times less than the undisturbed soil of the RWMC. In addition, the injected grout must reduce accessible voids by 80%. 5 refs., 2 figs., 1 tab.
