【 摘 要 】

This Special Analysis (SA) addresses disposal of high-concentration I-129 wastes in the Intermediate Level (IL) Vaults at the Savannah River Site E-Area Low-Level Waste Facility. This SA addresses both the existing activated carbon vessels already placed in the IL Vault and any type of future waste that contains a high concentration of I-129. An equation is developed that relates a wasteform's vault inventory limit of I-129 to the wasteform's measured Kd. This SA was prepared to meet the requirements of the U.S. Department of Energy Order 435.1 (DOE 1999a). The order specifies that a performance assessment or SA should provide reasonable assurance that a low-level waste disposal facility will comply with the performance objectives of the Order. In addition to the performance objectives, the Order requires, for purposes of establishing limits on the concentration of radionuclides that may be disposed of near-surface, an assessment of impacts on water resources and on hypothetical persons assumed to inadvertently intrude for a temporary period into the low-level waste disposal facility.
