【 摘 要 】

The objective of this AVS testing program is to use bench-scale test equipment to produce a vitrified product at maximum waste loading from the specified AZ-101 waste simulant and conduct a TTT analysis using laboratory scale melts to show compliance with the DOE Waste Acceptance Product Specifications for Vitrified High-Level Waste Forms (WAPS). The vitrified product complies with the following WAPS. A borosilicate glass with a waste loading of 60.9-wt% was produced from a slurry feed of AZ101 simulant. Glass durability testing, glass characterization testing, and testing methodology were performed in accordance with the Department of Energy approved Test Plan. The glass has two crystalline phases and good uniformity of composition. The Product Consistency Test on the 6 location-specific samples are at least 1 to 2 orders of magnitude below the mean PCT results for the EA glass. Standard deviations were less than 10% of measured values. The glass transition temperature averaged 658 {+-} 9 C. A TTT diagram was produced. There was measured cesium loss of about 2%, and compliance with the Universal Treatment Standards.
