Abstract: Commercially available melter technologies were tested during
1994-95 as part of a multiphase program to test candidate technologies
for vitrification of the low-level waste (LLW) stream to be derived from
retrieval and pretreatment of Hanford Site tank wastes. Seven vendors
were selected for Phase 1 testing to demonstrate vitrification of a high
sodium content liquid LLW simulant. The tested melter technologies
included four Joule-heated melters, a carbon electrode melter, a
combustion melter, and a plasma melter. Various dry and slurry melter
feed preparation processes were also tested. Various feed material
samples, product glass samples, and process offgas streams were
characterized to provide data for evaluation of process decontamination
factors and material mass balances for each vitrification technology.
This report describes the melter mass balance evaluations and results
for six of the Phase 1 LLW melter vendor demonstration tests.
