Operation of a laboratory-scale glass melter to vitrify ICPP zirconia calcine

Creators

Description

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 11000C using 1.5 KW. The melter has been dismantled for metallurgical examination and modified twice. The third version is now in operation
