This data package, milestone C95-02.02Y, provides a brief observation and operation report on available data for the Small-Scale High Temperature Melter-1 (SSHTM-1) feed preparation activities. The test was conducted in two melter feed batch segments prepared from two different feed preparation flowsheets. Testing primarily addressed feed preparation alternate flowsheet options tested in the laboratory to mitigate potential safety issues related to generation of hydrogen and ammonia, to produce acceptable melter feed rheological properties, to maximize total waste oxide loading in the glass, to simplify the vitrification flowsheet, and to increase vitrification flowsheet processing rate. The two flowsheets selected for testing were (1) no reductant addition and titration with HNO{sub 3} to provide an acceptable melter feed rheology near the target oxide loading (Alternate HTM Flowsheet 1), and (2) titration with glycolic acid, an alternate reductant to HCOOH (Alternate HTM Flowsheet 2)
