High-Level Radioactive Waste Management Program at the National Reactor Testing Station

A status report is given on high-level radioactive waste management at the irradiated fuel reprocessing plant (ICPP) at the National Reactor Testing Station (Idaho National Engineering Laboratory). Interim storage of high-level liquid waste, calcination of liquid waste by fluidized bed calcination and storage of calcine in bins is summarized over the past decade. Results are given on the conversion of granular calcine to cermet, glass-ceramic, and ceramic forms for alternative long-term storage requirements. The environmental impact of effluents released in the course of waste solidification is given for the ICPP.
