An innovative method for mixed waste disposal at the Savannah River Site`s high level liquid waste tank farms
The In-Tank Precipitation (ITP) facility located at the U.S. Department of Energy`s Savannah River Site (SRS) in Aiken, SC is responsible for the primary decontamination of high level radioactive liquid waste generated from reactor operations. Treatment of this waste at the ITP facility requires the use of specially designed cross flow sintered metal filters which physically separate the waste into a high activity precipitate and a decontaminated salt solution. In processing the waste the filters are expected to eventually become fouled and plugged with solids material requiring the filters` removal and replacement. Disposal of these fouled filters is complicated in that the solids material plugging the filters contains hazardous constituents as defined by the Environmental Protection Agency`s (EPA) Resource Conservation and Recovery Act (RCRA). The filters will therefore be prohibited from land disposal options unless treated to the appropriate Land Disposal Restriction (LDR) standard. Personnel at SRS have developed a unique treatment and disposal alternative which includes macro-encapsulation, off-gas treatment and the appropriate radiation shielding. SRS has obtained EPA agreement with this new process in the form of an approved ``Treatability Variance`` from the LDR regulations.
