Corbett, R A; Bickford, D F

Incineration and vitrification of radioactive waste subjects equipment to alkaline or acid fluxing, oxidation, carburization, and sulfidation. Appropriate materials of construction must be selected to avoid rapid equipment failure. High chromium alloys have been tested in the laboratory using simulated waste formulations. Laboratory screening tests indicate that alloys with greater than 40% chromium provide superior resistance to attack. Ductile chromium is viable for submerged electrodes and equipment in the vapor space, however, is subject to melt line attack at the glass/air/chromium interface of vitrification melters. 9 refs., 5 figs., 4 tabs.
