Industrial operation of Joule heated ceramic melters Type EP-500 and Pamela for vitrification of high radiaoctive waste
- and others
During the operation of a nuclear reactor radioactive fission products are formed. In the reprocessing process most of this radioactive inventory ends up as high-level liquid waste (HLLW), steel tanks being used for interim storage. Certainty, tank storage is not a long-term solution for isolating these wastes from the biosphere. There is, therefore, a demand for producing solid waste packages for final disposal in a geological repository. As waste conditioning has to take place in hot cells, the process should be kept as simple as possible. At present vitrification of HLLW is favoured worldwide. In this process, the radioactive fission products are embedded in a glass matrix, mainly in the chemical form of oxides, with a waste loading of about 8 to 25 wt.-% depending on the individual composition of the HLLW. In the following chapters, experiences in Russia and Germany are reported, which should be concentrated in a joint vitrification project.
