Characterization of Defense Waste Processing Facility (DWPF) Glass and Deposit Samples from Melter No.2

PDF Version Also Available for Download.

Description

The Defense Waste Processing Facility (DWPF) Engineering requested characterization of three glass samples that were taken from Melter number 2 after the waste loading had been increased, e.g. after the new quasicrystalline liquidus model had been implemented and after DWPF switched from processing with Frit 200 to Frit 320. These samples were taken after DWPF observed very rapid buildup of deposits in the upper pour spout bore and on the pour spout insert while processing the high waste loading (approximate 38 wt percent feedstock). Rapid deposition in these locations had not occurred prior to this and, in turn, stopped after ... continued below

These samples were taken after DWPF observed very rapid buildup of deposits in the upper pour spout bore and on the pour spout insert while processing the high waste loading (approximate 38 wt percent feedstock). Rapid deposition in these locations had not occurred prior to this and, in turn, stopped after waste loading decreased. These samples were evaluated at SRTC using various analytical techniques for potential impacts on pouring problems recently experienced by the DWPF.
