f Demonstration Of Geophysical Methods For Burial Ground Geophysical Characterization Study At The Doe Savannah River Site

Rust Geotech, operating contractor at the U.S. Department of Energy Grand Junction Projects<br>Office (DOE-GJPO), conducted a demonstration of the trench boundary and large-object<br>location capabilities of five nonintrusive geophysical methods in the Low-Level Radioactive<br>Waste Disposal Facility (LLRWDF) at the DOE Savannah River Site (SRS). The plan for<br>Resource Conservation and Recovery Act (RCRA) closure of the SRS LLRWDF specifies inplace<br>compaction of “B-25” metal boxes containing low-level radioactive wastes. The boxes<br>are buried in Engineered Low-Level Trenches (ELLTs) at the facility. To properly guide and<br>control the compaction operation, the coordinates of the trench boundaries must be<br>determined to an accuracy within 5 feet and the outer edges of the metal boxes in the<br>trenches must be determined to within 2 feet.
