Lot No. 2 of Frit 202 for DWPF cold runs. [Waste Processing Facility]
In the DWPF (Defense Waste Processing Facility), glass forming chemicals will be added to the waste in the form of premelted glass frit. On an oxide weight basis, DWPF glass will consist of approximately 64 wt% glass frit, 8 wt% precipitate hydrolysis aqueous product, and 28 wt% sludge. The glass frit and the precipitate hydrolysis aqueous product together make up what is called the glass-former composition. Current plants are to control the composition of the frit through the procurement specifications and chemical analyses of representative lot samples. The following report was prepared at the end of 1992 and summarizes the evaluation of the second lot sample of DWPF Frit 202 from Cataphote Inc. The frit was received and evaluated for moisture, particle size distribution, organic-inorganic carbon and chemical composition. The moisture content was within specification. The particle size determination indicates that there was a fraction of a percent more coarse frit (+80 mesh) than the specified amount. The fine end of the distribution was within specification. A representative sample was submitted to Corning Engineering Laboratory Services for chemical analyses. The sample was split and two dissolutions prepared. Each dissolution was analyzed on two separate days. The results indicate that there is a high probability (>95%) that the silica content of this frit was below the specification limit of 77.0 [plus minus] 1.0 wt%. The average of the four analyzed values was 75.3 wt% with a standard deviation of 0.21 wt%. All other oxides were within the elliptical limits established for this product. The vendor was notified that the material was not acceptable for DWPF cold runs.
