Final Report Melter Tests with AZ-101 HLW Simulant Using a DuraMelter 100 Vitrification System. VSL-01R10N0-1, Rev. 1, 2/25/02.

摘要

This report provides data, analyses, and conclusions from a series of tests that were conducted at the Vitreous State Laboratory of The Catholic of America (VSL) to determine the processing rates that are achievable with AZ-lOl HLW simulants and corresponding melter feeds on a DuraMelter 100 (DMI00) vitrification system. One of the most critical pieces of information in determining the required size of the RPP-WTP HLW melter is the specific glass production rate in terms of the mass of glass that can be produced per unit area of melt surface per unit time. The specific glass production rate together with the waste loading (essentially, the ratio of waste-in to glass-out, which is determined from glass formulation activities) determines the melt area that is needed to achieve a given waste processing rate with due allowance for system availability. Tests conducted during Part Bl (VSL-00R2590-2) on the DMI000 vitrification system installed at the Vitreous State Laboratory of The Catholic University of America showed that, without the use of bubblers, glass production rates with AZ-I0l and C-I06/AY-I02 simulants were significantly lower than the Project design basis rate of 0.4 MT/m2/d. Conversely, three-fold increases over the design basis rate were demonstrated with the use of bubblers. Furthermore, an un-bubbled control test using a replica of the melter feed used in cold commissioning tests at West Valley reproduced the rates that were observed with that feed on the WVDP production melter. More recent tests conducted on the DM1200 system, which more closely represents the present RPPWTP design, are in general agreement with these earlier results.
