摘要

Over the course of several years, we have examined the viability of treating low-level mixed wastes from several US Department of Energy (DOE) sites by vitrification. In particular, extensive studies have been performed on actual low-level mixed wastes from the Fernald site in Ohio. We have shown that it is possible to produce durable glasses (pass the US EPA TCLP test and perform comparably to high-level waste glasses on the PCT test) with waste loadings of 80-98%. The results of these vitrification studies have been used to up-scale from laboratory scale melters to a demonstration-scale melter operating at the Fernald site with a nominal glass production rate of 300 kg/day. This paper focuses on the difficulties that we have encountered in characterizing and working with actual waste sludges and the solutions that we have developed. [References: 5]
