Reduction of Constraints: Phase 2 Experimental Assessment for Sludge-Only Processing
The homogeneity constraint is currently used by the Defense Waste Processing Facility (DWPF) to discriminate compositions that are likely to result in glasses containing glass-in-glass amorphous phase separation from compositions that are likely to be homogeneous. The durability of glasses containing amorphous phase separation can be unpredictable so a phase separation discriminator was developed and implemented as part of the Product Composition Control System (PCCS) to avoid processing unacceptable phase separated glasses in the DWPF. However, implementation of the homogeneity constraint (i.e., the amorphous phase separation discriminator) has resulted in an overly restrictive operating region for the DWPF (i.e., it has limited processing in regions that would have resulted in acceptable glasses being produced). Therefore, studies were initiated to determine if the homogeneity constraint could be eliminated while still allowing processing flexibility for DWPF during sludge-only processing. At the same time, the alternative constraint must not compromise product quality.
