Immobilization of Neutralized Cladding-Removal Waste in a Cement-Based Grout

Abstract

Oak Ridge National Laboratory (ORNL) is providing technical support for the Transportable Grout Facility (TGF) currently being designed by Rockwell Hanford Operations in Richland, Washington. The grout formulas to be used in the TGF for disposal of low-level radioactive waste streams are being developed at ORNL. One such waste stream, neutralized cladding-removal waste (NCRW), has been identified for disposal, and a grout formula has subsequently been developed. The development of this formula required extensive testing to achieve adherence to several performance criteria. Both the grout formula and the results of this testing are presented.
