Comparison of HLW Glass Melting Rate Between Frit and Glass Forming Chemicals Using X-Ray Computed Tomography

“…As previously mentioned, the results of the MRF have been used directly or in conjunction with SMRF testing to recommend frits and sludge preparation strategies to DWPF for sludge batches 1B through 6. 6,8,[14][15][16][17][18][19][20][21][22][23][24][25] In addition, these tools have allowed WL versus melting rate curves to be generated, which have been used to demonstrate where optimal waste throughput can be achieved for a given melter feed.…”

Melt Rate Testing for Sludge Batch 6

“…6 These tests showed that higher concentrations of B 2 O 3 in the frit relative to that of Frit 418 appeared to improve melt rate. However, when a higher concentration of B 2 O 3 was coupled with a lower concentration of Na 2 O relative to Frit 418, melt rate did not appear to improve.…”
