Georgia Tech Final Report Demonstration In Situ Plasma Vitrification Technology for Savannah River Site Contaminated Soils (U)

Previous experience with in-situ (Joule-heated) vitrification (ISV) of Savannah River site (SRS) highly weathered soil, has shown that the SRS soil is very refractory and a poor electrical conductor. These findings bring into question the likelihood of utilizing the Joule-heat type of vitrification treatment for waste sites and basins at SRS. An alternative approach may be in-situ plasma vitrification (ISPV). The ISPV approach provides a similar vitrified product and also has a safety advantage in that the melting is initiated at the bottom of a borehole compared to top-down melting for Joule heated ISV
