Gombert, D.; Pong, M. Y.

A 1.5 litre joule-heated glass melter was built to test the applicability of electric melting to vitrify simulated high-level calcined defense waste. The Inconel 690 electrodes have a high but acceptable corrosion rate and showed some phase separation. The K-3 refractory showed excellent resistance to the glass. Off-gas tests indicate negligible fluoride volatility. The melter operates at 1100/sup 0/C using 1.5 KW. The melter has been dismantled for metallurgical examination and modified twice. The third version is now in operation.
