Description
A vitrification facility was conceptually designed so that all Low- and Intermediate-Level Radioactive Waste (LILW) from a pressurized water reactor (PWR) could be converted into glassy/slag waste forms with the minimization of the entrainment of volatile nuclides. Generation trends, radiological characteristics and chemical composition for LILW from Korean NPPs were examined. In order to select the most promising melters suitable for the goals, several melters that were likely to be applied to LILW vitrification were compared with one another with respect to each waste stream. An off-gas treatment system and a waste feeding system are suggested to minimize the input of volatile chemicals and radionuclides into effluents, especially, considering chemicals generated when each waste is pyrolyzed in molten glass or a pyrolysis chamber
