Data Summary Report Small Scale Melter Testing of HLW Algorithm Glasses: Matrix 1 Tests. VSL-07S1220-1, Rev. 0, 7/25/07.

摘要

Eight tests using different HLW feeds were conducted on the DMl00-BL to determine the effect of variations in glass properties and feed composition on processing rates and melter conditions (off-gas characteristics, glass processing, foaming, cold cap, etc.) at constant bubbling rate. In over seven hundred hours of testing, the property extremes of glass viscosity, electrical conductivity, and T(sub 1)%, as well as minimum and maximum concentrations of several major and minor glass components were evaluated using glass compositions that have been tested previously at the crucible scale. Other parameters evaluated with respect to glass processing properties were +/-15% batching errors in the addition of glass forming chemicals (GFCs) to the feed, and variation in the sources of boron and sodium used in the GFCs. Tests evaluating batching errors and GFC source employed variations on the HL W98-86 formulation (a glass composition formulated for HLW C-106/ AY-102 waste and processed in several previous melter tests) in order to best isolate the effect of each test variable. These tests are outlined in a Test Plan that was prepared in response to the Test Specification for this work. The present report provides summary level data for all of the tests in the first test matrix (Matrix 1) in the Test Plan. Summary results from the remaining tests, investigating minimum and maximum concentrations of major and minor glass components employing variations on the HL W98-86 formulation and glasses generated by the HLW glass formulation algorithm, will be reported separately after those tests are completed.
