Vitrification of High-Level Radioactive Waste in a Pilot-Scale Liquid-Fed Ceramic Melter

摘要

Under the sponsorship of the Nuclear Waste Treatment Program (NWTP), a high-level radioactive waste vitrification system has been installed in a Radiochemical Engineering Facility at Hanford, Washington. The facility is designed for remote operation of equipment using master-slave manipulators and overhead cranes. The pilot-scale radioactive system consists of a melter, canister handling turntable, glass-level detection system and supporting waste preparation, offgas treatment and condensate treatment systems. The vitrification system will be operated with radioactive wastes to test remote equipment features and process performance. Destructive and nondestructive methods will be used in the characterization of the waste glass product after canisters are filled with specific waste compositions. 4 refs., 9 figs.
