The Salt Waste Processing Facility (SWPF) is a proposed nuclear waste treatment facility for the United States Department of Energy's Nuclear Reservation Savannah River Site in Aiken, South Carolina. It is being designed and constructed by the Parsons Corporation for treatment of nuclear salt waste and is expected to become operational in 2012-2013. ==Background== The Savannah River Site (SRS) presently contains legacy nuclear waste from the production of nuclear materials between 1951 and 2002. The nuclear waste is stored in large (typically nominal capacity) underground double walled storage tanks located in F-Area and H-Area tank farms. Upon completion in 2016, the Salt Waste Processing Facility (SWPF) will be the cornerstone of the Savannah River Site (SRS) salt processing strategy. It is designed to be capable of processing of salt solution per year. The waste currently in storage at SRS presently includes approximately of salt solution that must be processed, of which are projected to be processed through SWPF. SWPF will use specific processes that have been developed at Oak Ridge National Laboratory and Argonne National Laboratory using annular centrifugal contactors and that will be the state-of-the-art methods to target the removal of caesium-137, strontium-90, and actinides from SRS salt wastes. SWPF will remove approximately 99.998% of the caesium-137/barium-137 (metastable) activity while also removing strontium and actinides (Ref 1).
