Special Analysis for Disposal of High-Concentration I-129 Waste in the Low-Activity Waste Vaults at the E-Area Low-Level Waste Facility
This Special Analysis (SA) addresses disposal of wastes containing a high concentration of I-129 in the Low Activity Waste (LAW) Vaults at the Savannah River Site E-Area Low-Level Waste Facility. These wastes were analyzed by computer modeling incorporating a laboratory-measured I-129 Kd. A Kd represents partitioning of a contaminant between solid particles (i.e., the waste) and liquid that can transport the contaminant. These wastes exhibited high Kds indicating a slow release rate that typically is manifested as low aquifer concentrations and high vault-inventory limits. This SA applies to ER and ETF wastes and any type of future waste that contains a high concentration of I-129. This SA was prepared to meet the requirements of the U.S. Department of Energy Order 435.1 (DOE 1999). Because the Performance Assessment (PA, McDowell-Boyer, et al., 2000) analyzes generic wastes, this report focuses on wastes with a high I-129 concentration. Common information from the PA is not duplicate d in this report.
