摘要

The radioactive tank waste treatment programs at the U. S. Department of Energy (DOE) have featured joule heated ceramic melter technology for the vitrification of high level waste (HLW) and that technology has also been selected for the Hanford Tank Waste Treatment and Immobilization Plant (WTP). The melter technology used at the West Valley Demonstration Project (WVDP) in New York and at the Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) process(ed) HLW in ceramic melters at an operating temperature of 1150DGC. Those melter designs rely on natural convection in the viscous molten glass for melt pool mixing in order to provide heat and mass transport to and from the cold cap reaction zone. In advancing the technology, EnergySolutions/VSL have demonstrated on very large scale melters (EnergySolutions M-Area facility, WTP HLW pilot melter, and the WTP LAW pilot melter) that active mixing of the glass pool using EnergySolutions's patented bubbler technology increases heat and mass transport, which leads to significantly increased melt rates and reduced temperature gradients within the glass pool. In addition, the active melt pool mixing tends to promote the suspension of crystalline phases. The present WTP HLW melter design has a nominal operating temperature of 1150(deg)C and incorporates an active glass bubbler system which provides improved glass production rate (up to 7.5 MT of glass per day for two HLW melters).
