Nearly 34 million gallons of high-level waste (HLW, the radioactive waste product associated with the dissolution of spent nuclear fuel rods for the recovery of weapons grade materials) await disposition at the Savannah River Site (SRS). The current design for the Salt Waste Processing Facility at the SRS includes use of monosodium titanate (MST) to remove and concentrate the strontium (Sr) and actinides [uranium, plutonium (Pu) and neptunium (Np)] from HLW salt solutions. However, the River Protection Program (RPP) at the Hanford Site in Washington State proposes use of potassium permanganate addition for Sr and actinide removal from RPP HLW. Recent studies at the SRS indicate sodium permanganate treatment holds promise for use in the decontamination of Sr and actinides in SRS HLW.
