Assessment of Soil Erosion Methods for Sludge Recovery, Savannah River Site

摘要

The applicability of soil erosion methods for recovery of high-level radioactivewaste (HLW) from selected storage tanks at the Savannah River Site (SRS) was assessed conceptually. Soil erosion methods are defined as the processes of soil detachment, entrainment, transport, and deposition. The assessment involved four phases: (a) data collection, (b) evaluation of potentially applicable erosion models and methods, (c) development of a numerical model of sludge erosion, and (d) documentation of methods and results. Analyses described in this report were made on existing data developed at SRS using existing analytical methods and models. Four topics are discussed: (a) erosion processes for sludge recovery, (b) application of soil erosion to sludge recovery at SRS, (c) numerical simulation of sludge erosion, and (d) summary and recommendations. Results of the investigation indicate that erosion methods can be effective in the recovery of waste sludge. The natural internal order of erosional networks provides a system that is predictable, efficient, and quickly responsive to artificial control. Numerical simulation of erosional systems indicated that an erosional system developed in SRS HLW would be an efficient way to recover HLW.
