The Salt Waste Processing Facility (SWPF) at the Savannah River Site will become operational in late 2019, which will send high activity streams to be vitrified at the Defense Waste Processing Facility (DWPF). These high activity streams include monosodium titanate and sludge solids from the sludge solids receipt tank and Cs-containing strip effluent. Using the DWPF Product Composition Control System models, a frit was optimized to support Sludge Batch 9 coupled operation with SWPF. The frit was selected to provide operational flexibility by allowing an acceptable waste loading to be targeted while maintaining an operating window of at least +/- 4 percentage points around this target.
