Summary:

To assess the long-term hazard potential associated with the burial of partially decontaminated process equipment, burial emplacements of equipment from an irradiated-fuel separations building (canyon) are being exhumed and examined. One piece of equipment, a Purex feed adjustment tank that was retired in 1957 from service in a hot canyon at the Savannah River Plant, has been exhumed and studied. This paper describes sampling of neighboring soil, tank exhumation, results of assay of soil and tank, and conclusions. Assays of the tank and soil show that only 1 mCi of /sup 137/Cs and 0.4 mCi (7 mg) of /sup 239/Pu remain on the surfaces of the tank; amounts of these radionuclides in neighboring soil are substantially less. Radionuclides from the contaminated surface of the tank migrated into neighboring soil. Of the three nuclides studied, /sup 90/Sr migrated most extensively, as observed previously. /sup 239/Pu contents of the tank and neighboring soil were less than the 10-nCi/g total transuranic nuclide content allowed under ERDA standards for burial of nonretrievable waste. This paper also describes plans for future studies including (1) exhumation of other equipment and (2) in-place lysimeter and laboratory-column tests for studying radionuclidic migration in soil.
