Physical and chemical properties of the products of in situ vitrification engineering tests 5, 6, and 7

In situ vitrification (ISV) is an in situ thermal treatment process that is being investigated by the Idaho National Engineering Laboratory (INEL) for application to buried waste sites. ISV is a thermal treatment process that converts contaminated soil into a chemically inert and stable glass and crystalline product. The INEL is evaluating whether the treatment process is a viable one for remediating a buried mixed transuranic waste site at the INEL Subsurface Disposal Area (SDA). The SDA is a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) site. As part of the INEL investigation, a series of tests have been performed that address issues associated with vitrification of buried waste. Two pilot ISV tests and four tests at laboratory scale, formerly called engineering scale, were performed in 1990 to support the INEL investigation. The chemical composition and leaching of the produce glass is described
